With the vigorous development of China's automobile industry, the number of car ownership has increased rapidly in recent years, and the problem of car noise has become more and more prominent and has received increasing attention. China is a country with public transportation as the mainstay. The proportion of long-distance buses, tourist buses and buses on the road is much higher than the world average. Therefore, passenger car noise pollution can not be ignored.
Domestic bus manufacturers have reached international standards in the design, safety and reliability of passenger car products, but little work has been done on passenger car noise control. The aluminum honeycomb sandwich material is a multifunctional composite material having a honeycomb structure made of aluminum foil and high-strength adhesive. Due to the porous structure of the honeycomb, this material exhibits good sound absorption, sound insulation performance and light weight, and is an ideal noise reduction material for passenger cars.
Honeycomb foil is generally 3003 aluminum plate, state H18, thickness between 0.03-0.08mm, mostly between 0.04-0.06mm, there are also a few 5052 alloy honeycomb aluminum foil, but due to high cost, very small amount, product to plate type The thickness requirements are stricter and the requirements on the board surface are relatively low.
The honeycomb aluminum foil market is currently dominated by Mintai and some small aluminum foil factories in China. The small factories also have a place in the market with low price and flexible business. Mingtai's honeycomb aluminum foil products are slightly higher than other manufacturers' products, but with high quality. For the advantage, some manufacturers of honeycomb panels with their own brands will often choose Mingtai's products. At present, the whole big economy is weak, the whole market is in transition, and all industries are shuffling. The industry is invincible and needs to be protected by high quality. Therefore, Mingtai's business philosophy is based on the long-term effectiveness of quality service customers.
