The customized qt8-15 automatic brick making machine have been tested in the factory according to relevant regulations, but due to long-distance transportation and long-term storage, the following inspections should be carried out when installing the brick machine:
1. Check whether the brick machine is damaged or deformed during transportation (especially pay attention to the hydraulic pipeline).
2. Check whether the fasteners in the main parts of the brick making machine are loose.
3. Check whether the oil cylinders and lubricating points of each working part are filled with oil as required, and whether the oil quantity is appropriate.
4. In addition, the qt8-15 automatic brick making machine must be fully wiped. Before the test machine, the sliding parts of the moving parts should be lubricated according to the regulations. If the machine needs to be disassembled due to transportation, it can be divided into forming device, plate feeding device, feeding device, brick discharging device, palletizing device, phase electronic control device, etc., and it should be assembled in place according to the assembly relationship during installation.

1. Start the concrete pump and run empty. If the temperature is low, the empty operation time should be longer, because the temperature of the hydraulic oil will only be able to pump concrete if it rises above 15℃. Do not use pressure test (overflow valve high pressure overflow) to speed up the rate of heating.

2. A certain amount of clean water is added to the hopper of concrete pump to moisten the hopper, distributing valve and concrete conveying pipeline of concrete pump.

3. Add a certain amount of cement mortar into the hopper to lubricate the entire concrete conveying pipeline.

China galvanized steel coil supplier said that construction and light industry are the main markets for galvanized coils, and the demand is about 30% of the galvanized coil. According to the speed of national economic development and the previous consumption base, the total demand in the first half of the year is about 4 million tons, equivalent to 180,000 tons of refined zinc consumption.

From the demand for galvanized steel coils in the home appliance industry, air conditioners are the main products for consuming galvanized steel coils. The back panel of the air conditioner indoor unit and the cabinet, the inner part, the outer casing of the outdoor unit, and the interior are all made of the galvanized coil, and an average of one air conditioner consumes 22 kg of the galvanized coil. In addition, each washing machine consumes approximately 8 kg of galvanized rolls, and each refrigerator consumes approximately 3 kg of galvanized rolls.

The automotive industry is also a major industry for consuming galvanized coils, which is much larger than the home appliance industry. Since 2006, the output of China's automobiles has increased rapidly, especially in the sedan. According to the calculation of about 350 kg of galvanized coil per vehicle, the demand for galvanized coils in China's auto industry is at least 3.1 million tons per year.

The construction industry needs a large number of galvanized coils to manufacture ventilation ducts. For example, a medium-sized building requires more than 25,000 square meters, and each specification has a total of 200 tons. Of course, this is not a waste of processing. At present, there are many large projects under construction in the country, and the demand is also very large.

Now the rapid development of science and technology, a lot of advanced equipment has been widely used, high quality PPGI corrugated roofing sheet is also so, with excellent performance, has been recognized by the industry, the following takes you to understand in detail.

PPGI corrugated roofing sheet area calculation rules:
1. Outdoor stairs and walkways are calculated according to the sum of natural projection areas;

2. The volume area is calculated by the length and width of the outer wall and multiplied by the number of floors;

3. Total area =1+2+3;

4. The canopy is calculated by half of the horizontal projection area;

5. Unless otherwise specified, the calculation method of engineering quantity shall be settled in accordance with the above calculation formula;

6. There are two stairs in the standard house, each one of the left and right gables. Each stair is 4.5 square meters.

PPGI corrugated roofing sheet for sale, the choice of color coated plate mainly refers to the mechanical properties, substrate type and coating weight, color aluminum plate, front coating properties and reverse coating properties of the choice. Use, corrosive environment, service life, durability, processing and deformation degree are important factors to consider when choosing PPGI roofing sheet.

Factors such as service life and durability are selected. Aluminum-magnesium zinc plate price, anticorrosion is one of the main functions of a painted plate, the type of substrate and coating weight is the main factor affecting the corrosion resistance of painted plate, the construction of painted plate usually choose hot dip galvanized substrate and hot dip aluminum-zinc alloy substrate, mainly because the two kinds of substrate corrosion resistance is good.

The choice of positive coating performance mainly refers to the choice of coating type, coating thickness, coating color difference, coating luster, coating hardness, coating flexibility, adhesion, coating durability, and other properties.

The commonly used topcoats are polyester, silicon-modified polyester, high-durability polyester, and polyvinylidene fluoride. There are certain differences in hardness, flexibility, adhesion, and durability of different topcoats. Polyester is the most widely used coating; Aluminized zinc coil, silicon-modified polyester modified by organosilicone, has high durability and luster. High durability polyester not only has the advantages of polyester but also improves the durability and has high-cost performance. Polyvinylidene fluoride has excellent durability and coating flexibility. Shanghai aluminized zinc plate, the top coating is mainly determined by the use, corrosive environment, service life, durability, processing mode and degree of deformation and other factors.

Although roll forming of high-quality GL Galvanized Steel Coil is the most commonly used colored plate forming method, for the production of roof panels and wall panels, there may be a need for blank holder or other accessories, sometimes also need to be as large as possible to improve the bending part of the bending radius. It is also important to avoid scratches on the coating surface during the blanking process, which can be avoided by applying polyurethane or hard plastic to the die.

Proper die clearance should be maintained during the pressing of GL galvanized steel coil. Embossing is also a type of color-coated plate forming, the embossing process to ensure that the coating and coating are not damaged, in order to ensure that the color painted plate durability is not affected, also need a low enough embossing sharpness and depth. Stamping, grooving, and punching are other forming methods of the painted plate.

For these molding methods, the influence of many factors discussed previously, such as mold clearance and paint flexibility, is also important. For example, stamping methods are used to produce roofing corrugated panels for use in rural areas.

The following awareness and care must be taken in the field construction of GL galvanized steel coils to ensure the good performance of the painted steel plates. Handling abrasions usually present as scratches or backside paint particles adhering to the surface of the painted steel plate. Defects arise from poor handling, inadequate paint curing, and irregular surface conditions. Degree of solidification, hardness, and lubricity of paint affect abrasion defects.

Good roller lubrication and a suitable back coat will help to reduce abrasions. Sometimes a transparent, strippable film can be applied to the surface of the steel plate to avoid handling abrasions. Scrapes may occur in the hoisting in the baling factory. In order to avoid scrapes caused by bending, the hoisting equipment of long bales should be able to support most of the length of bales. Bundles must be fixed vertically and horizontally.

Direct contact with other objects, such as structural parts, must be avoided when transporting GL galvanized steel coils in vehicles. When using forklifts to carry, care must be taken to ensure that the bales do not bend excessively or cause steel plate abrasions.

A feasible method to prevent the speed of aging of the GI steel coil in advance.

GI steel coil with spangles made in China used for a long time or not used for a long time may occur aging, why to say it, long-term construction or storage will be exposed to the sun. Aging occurs after a long time of exposure to light, which we cannot avoid. However, we can prevent and reduce the aging rate in advance in ordinary times. So what should we do?

The first necessary condition for aging or photochemical reaction of PPGI corrugated roofing sheet is that the surface composition of the GI steel coil can absorb radiation energy. Secondly, the absorption of molecular radiation energy is greater than the molecular bond energy, the color coating can occur degradation. The shorter the wavelength, the higher the energy.

According to the above theory, the aging of the high-quality PPGI corrugated roofing sheet in the atmospheric environment is that the coating molecules absorb the energy of the ultraviolet band in the sunlight which is higher than its molecular bond energy, leading to the degradation of the coating molecules. With the aging of the coating, the base material body is gradually lost, and the coating surface gradually becomes rough and lose light. This loss of base material eventually leaves relatively stable pigment particles in the form of an unbonded powder on the coated surface, a process known as pulverization.

To sum up, there is a big difference in the aging resistance of PPGI corrugated roofing sheet with different coating thickness, the aging resistance of thin coating color coating board is poor, the aging resistance of normal thickness coating is relatively good.

Therefore, it is not feasible to reduce the production cost of PPGI corrugated roofing sheet by reducing the thin coating, which will inevitably bring serious quality problems.

Precautions for the use of galvalume steel coating steel coil:

1. If water leakage occurs in the storage and loading and unloading of the wholesale galvalume steel coating steel coil, it may lead to rust. Please pay close attention to the loading and unloading, dampness and condensation in rainy days. In addition, high humidity, an acidic environment is not conducive to storage, storage in dry, clean indoor.

2, if the use of organic solvents to wipe the surface of the galvalume steel coating steel coil, the surface may cause the loss of galvanized coating or peeling, please pay full attention.

3, if the attachment of oil and other foreign bodies, may affect the performance of aluminum zinc steel coil, please pay full attention.

4. If the processing degree is high, the zinc layer may be damaged, please confirm before use.

5, with the passage of time, the galvalume steel coating steel coil may be reduced processing performance, tensile deformation and other conditions, in order to prevent this situation, it is recommended to use as soon as possible.

1. Mechanical property is an important index to measure the formability, is to determine and adjust the important parameters of the processing process, so high-quality PPGI corrugated roofing sheet processing should be considered first.

2. Pencil hardness, T bend, impact power, and other indicators are closely related to the processing performance, so it should be given full consideration.

3. The shape of the parts is complex, the degree of deformation is large, should use multi-pass forming. If a forming may be due to excessive deformation damage PPGI corrugated roofing sheet coating and substrate adhesion.

4. The processing should be based on the shape of the mold, deformation characteristics, process conditions and other factors to set the appropriate gap, gap setting should consider the thickness of PPGI corrugated roofing sheet coating.

5. Most of the high-quality PPGI corrugated roofing sheet coating can be used as a solid lubricant and can meet the lubrication requirements of the most forming process, some coatings can be adjusted by the formula to improve the lubricity of the coating. If the lubrication of the coating is insufficient, the lubrication can be improved by means of oil coating, wax coating, and protective film stripping. However, it should be noted that wet lubricant is easy to absorb dirt, should be removed before the installation of the painted sheet. Exfoliate protective film should be removed as soon as possible after construction.

The cold rolled steel coil factory in stock introduces that the traditional coatings can be divided into several categories. The top-grade coatings are fluorocarbon coatings, which can resist corrosion for almost 20 years. Generally from steel mills to distribute in the form of drums. We often see the color steel plate refers to the processed plate, the thickness of which is about 50 to 100 mm. It is composed of filler in the middle and color steel plate on both sides.
Among them, the thickness of the color plate is 0.4mm, 0.5mm, 0.6mm and other different thicknesses. The middle layer can be polyurethane, rock wool or foam plastics. Because of the special profiles, the construction speed of the factory building constructed with color steel sheets is very fast (such as Xiaotangshan Hospital in SARS), but the strength is low. The base plate of color coated steel sheet is cold rolled, hot galvanized and electro galvanized. The types of coatings can be divided into polyester, silicone modified polyester, polyvinylidene fluoride, and plastic sol.

China color corrugated steel sheet manufacturers fire experts pointed out that should focus on five aspects:

First, the use of rock wool with good fire performance as the core material, to prevent the use of polystyrene, polyurethane and other core materials, after the completion of the board room, the externally visible parts cannot be exposed.

Second, it is best to build a new hot sale color-coated corrugated roofing sheet to set up a number of layers should not exceed two layers, try to control one layer.

Third, in the process of use, some heat sources and fire sources must maintain a certain distance from the steel plate.

Fourth, the wires and cables should not be traversed from the core material. If it is necessary to pass through the protective casing, the socket and switch box should be made of a metal galvanized box and the surface mounting method should be adopted.

Fifth, the fire equipment should be in good condition and conditional, and a fire alarm should be installed to facilitate the rapid evacuation of personnel. Sixth, the office area, living area, and work area should be set separately, and a certain safe distance should be maintained between the color steel plate houses.

How do we choose to face a wide variety of coating types? Let the color-coated corrugated roofing sheet manufacturer introduce you to several environmental factors that affect the use of color coated sheets.
 
1. Temperature. The high-temperature coating is easy to soften, and the corrosive medium is easy to adhere. It is easy to penetrate into the substrate, and the oxygen content in the water will increase under high temperature, and the corrosion speed will increase at a certain temperature.
2. Humidity. The corrosion of the substrate in the incision of the color-coated plate and the damage at the processing is electrochemical corrosion, and the low humidity does not easily form an etching battery (ie, an electrochemical circuit).
3. Day and night temperature difference. The temperature difference is large and it is easy to condense, forming a condition of galvanic corrosion on the bare metal. In addition, the large temperature difference also leads to frequent cold and hot deformation of the coating, which accelerates the aging of the coating and the external corrosive medium easily penetrates into the substrate of the PPGI corrugated roofing sheet for sale.
4. The acidity of rainfall and rainfall. The large acidity of the rain is undoubtedly unfavorable for corrosion resistance. However, rainfall has a dual effect. For wall panels and roofs with large slopes, rainfall has the effect of cleaning the surface of the steel plate and washing away surface corrosion products. However, for low-slope roof slabs and poorly drained areas, rainfall is large. It is easy to cause corrosion to increase.
5. Wind direction and wind speed. The effect of wind direction and wind speed is similar to that of water, and it is often accompanied by it. It is a test for the joint of materials because the wind will cause the joint to loosen and the rain will penetrate into the interior of the building.
6. Corrosive sediments. For example, chloride ions, sulfur dioxide, etc. have accelerated the corrosion of PPGI corrugated roofing sheets. These deposits occur mostly in areas with serious coastal pollution and industrial pollution (such as power plants, smelters, etc.).

Composition of Color Steel Sheets

1. The substrate of the high quality color corrugated steel sheet can be divided into a cold rolled substrate, a hot-dip galvanized substrate and an electrogalvanized substrate.

2. The coating type of color steel plate can be divided into polyester, silicon modified polyester, polyvinylidene fluoride, plastisol.

3. The surface state of the color steel sheet can be divided into a coated sheet, an embossed sheet, and a printed plate.

4. The color of the color steel plate can be divided into many types such as orange, milk yellow, deep sky blue, sea blue, blush, brick red, ivory, porcelain blue, etc. according to the user's requirements.


Application of Color Steel Sheets

The market for color coated steel sheets is mainly divided into three parts: construction, home appliances, and transportation. The construction sector accounts for the largest proportion, followed by the home appliance industry, and the transportation industry only accounts for a small portion.

The color steel sheets for construction are generally made of hot-dip galvanized steel sheets and hot-dip aluminum-zinc steel sheets. They are mainly processed into high quality PPGI corrugated roofing sheet or composite sheets with polyurethane and are used for the construction of industrial buildings and airports, airports, warehouses, freezers, etc. The roof, walls, and doors of the building.

Home appliance color sheets are generally based on electro-galvanized and cold plates for the production of refrigerators and large air-conditioning systems, freezers, bread machines, and furniture.

The transportation industry generally uses electro-galvanized and cold sheets as substrates and is mainly used for oil sump and automotive interior parts.

1. After the installation of the aluminum-zinc-coated coil retaining structure is completed, it is an important part to ensure that the surface of the galvanized coil is not damaged during the whole installation process. Therefore, it should be noted that the on-site handling of aluminum zinc steel coil in stock should be lightly handled. Do not drag and pull, do not walk freely on the above; during the on-site cutting process, the bottom surface of the cutting machine should not be in direct contact with the galvanized coil surface. It is best to use a thin triple-rolled coil; do not use aluminum-zinc-rolled rolls and scaffolding during lifting. Collisions and frictions on pillars, brick walls, etc.; workers on the roof should wear shoes with no nails at the bottom; tools carried by operators should be placed in the tool bag, such as on a special cloth or on a roof. On other sheets; do not scatter other materials on the roof or contaminate the coil.

2. The encased structure of high quality galvalume steel coating steel coil is made of steel coil of less than 1mm. The construction load of the roofing should not be too large. Therefore, it is very important to ensure structural safety and construction safety: workers in construction cannot be piled up to avoid concentrated load. If it is too large, the wound surface will be damaged; the construction workers shall not run, fight, smoke or litter on the roof; the coils that are hoisted to the roof on the same day should be installed. If there are unmounted coils, they should be temporarily fixed. In order to avoid being blown off by the wind, causing accidents; in the morning, the roof is prone to dew, and the aluminum-zinc-coated surface of the sloped roof is slippery, and special protective measures should be taken.

3. Other problems that should be paid attention to during the construction of the aluminum-zinc-rolled enveloping structure: the surface iron filings are cleaned, the other removed aluminum-zinc-rolled heads, the aluminum alloy rivets are pulled off the irons; the sealant is sealed with sealant When the surface is cleaned, the sealant should be cleaned so that the sealant has a good bonding surface on the galvanized coil; the used sealant and other debris should be present in the respective carry-on garbage bags; The connection socket should be protected from rain to avoid accidents; the plastic protective film on the surface of the galvanized coil should be completely removed after completion.
