With the development of the NCP epidemic and the intensification of the flow of people back to the city, the future, such as masks, a class of personal protective equipment demand will increase greatly, although many masks business to 3 times the salary of employees back to the factory to work overtime, rushed to do the masks, but it is still difficult to ensure that the supply of the market masks to contribute to the fight against the epidemic and the other day, BYD, SAIC Wuling, GAC and other tickets to the automobile manufacturers announced that they will be rapid layout to increase the masks production line.
Why can these automobile manufacturers quickly put into production to pool their wisdom, deploy resources, and quickly put into production to the design and manufacture of protective material production equipment? From the automobile production process, a bunch of full of mechanical metal and mask production eight rod can not play, but do not know, the car is a need for a strong supply chain to sustain the product, from the appearance of metal parts to the interior plastic parts, from paint to textiles are involved in sustaining this huge supply chain will need many different industries suppliers, it can be said that the car manufacturers do not produce the production, they are just parts movers, The automakers do not produce, they are just parts movers and assemblers.
Taking BYD as an example, in recent years, it is well known that BYD has made great progress in automotive NVH, in order to do a good job in the cabin acoustic performance, BYD has found a senior South Korean NVH engineers - Che Hee-beom, who are from the vehicle acoustic vibration control, noise transmission path optimization, wind noise optimization, as well as optimization of acoustic packages and so on. Multi-faceted approach to provide the vehicle's quiet effect, one of which is the use of acoustic cotton, in the use of soundproofing materials BYD is not at all stingy, the entire vehicle native sound-absorbing cotton area of 4 square meters, exceeding the average level of the same class of models by 20%.
So how does sound-absorbing cotton absorb sound on a car? Here is to rely on mainly by polypropylene and polyester fiber materials constitute sound-absorbing cotton,? Through a special blowing fusion wire technology to control the diameter of the polypropylene fiber in 2mm, and winding in the diameter of 25mm polyester fiber. When sound passes through, the extremely fine polypropylene fibers and the tiny pores formed by the vibration and viscous consumption of kinetic energy into thermal energy, absorbing sound energy, at the same time, the polyester thick fibers to ensure that the product's fluffiness and compression resilience.
The sound-absorbing cotton material here is the same material with disposable medical masks with polypropylene fiber material, polypropylene high melting finger nonwoven fibers are heated and then drawn, repeatedly stacked to form a nonwoven, and nonwoven is an important material for disposable medical masks, and BYD has a better supplier of environmentally friendly polyester sound-absorbing cotton, the use of safe and non-toxic polymer chemical materials developed. Harmless to the human body, does not produce any pollution to the environment, very easy to load directly into the production of disposable medical masks, companies only need to increase the mask production line and find skilled workers, boot production is not a difficult task.
Medical masks are generally multi-layer structure, raw materials to polypropylene-based. From the mask material, polypropylene high melt finger nonwoven special material is the best choice, can be used for disposable surgical gowns, sheets, masks, cover cloths, liquid absorbent pads and many other aspects. Data show that 1 ton of high melting finger fiber material can produce about 200,000 protective masks or 5,000 sets of protective clothing, 1 ton of polypropylene medical transparent material can produce about 80,000 conventional disposable syringes, so it seems that the automobile manufacturers quickly put into production to the mask production is a congenital advantage, on the one hand, explains the strong sense of social responsibility, on the other hand, also highlights the enterprise to adapt to the market quickly and strong ability, it is reported that the BYD masks responsible for the BYD nonwoven fabrics are the best choice. It is reportedly responsible for the BYD mask production is BYD Precision Manufacturing Co., Ltd. is located in Longgang, Shenzhen, itself has a medical equipment design and sales qualifications.
Previously, BYD donated 10 million yuan, and additional donations of more than 1 million yuan of emergency medical supplies; at this moment, the war "epidemic" does not stop, masks and disinfectant is expected to be around February 17th mass production shipments (mask production capacity by the end of the month up to 5 million / day, disinfectant production capacity of 50,000 bottles / day) until the epidemic is alleviated and eliminated. mitigation and elimination.
