Under the epidemic situation, protective clothing has become a strategic material. The production and quality of protective clothing is more related to the life safety of countless people fighting in the front line of epidemic prevention and control. Since the outbreak of the epidemic, a local enterprise in Suzhou has been supplying more than 30 domestic and foreign enterprises with 2000 tons of basic material pur hot melt adhesive at the speed of "racing with life". If all these pur hot-melt adhesives are used to make protective clothing, 30 million sets can be produced. What is the secret of PUR hot melt adhesive in protective clothing? Why is this enterprise's pur hot melt adhesive so popular? Recently, the reporter walked into the enterprise named Suzhou golden gun New Material Co., Ltd. and revealed the secrets of this pur hot melt adhesive.
"Gunshot" sounds, fully guarantee the supply of protective clothing materials
Jingun New Material Co., Ltd. is a private enterprise mainly engaged in the production of adhesives in Suzhou. Pur hot melt adhesive is their main product. Before the Spring Festival, Cao Jianqiang, chairman of the company, gave all employees a holiday. "There is still a lot of inventory in the company to meet the needs of customers during the holidays." Cao Jianqiang said. However, the sudden novel coronavirus pneumonia situation has left the company's stock "zero" quickly.
On February 5, a letter of urgent assistance was sent to Cao Jianqiang. The other side is Henan piao'an group, a well-known enterprise specializing in the production of protective materials. In the letter of assistance, "the company urgently purchases two pur hot melt glue compounding machines for the production of protective clothing during the epidemic, in an emergency!"! Golden gun New Material Co., Ltd. is required to provide 4.5t pur hot-melt adhesive as raw material for production of protective clothing. The arrival time is before 5:00 p.m. on February 6. "
In the face of the severe situation of epidemic prevention and control, "gunshots" are orders. Cao Jianqiang immediately contacted the transportation team to overcome the road blockade and other difficulties during the epidemic, and delivered the pur hot melt adhesive to the designated place on time.
From that day on, Cao Jianqiang's phone did not stop. Letters of assistance came like snow. "The stock is insufficient, so it is urgent to return to work. If production is resumed as early as one day, the front-line prevention and control personnel will have more safety assurance. " Cao Jianqiang said. He took charge of the company's deployment of various prevention and control measures, paid close attention to the personal track of employees, and made every effort to investigate potential safety hazards. At the same time, according to the special needs of the company in the special period, the regulatory department also speeds up the handling of qualification and procedures and opens up a green channel.
On February 10, the roar of machines rang again in the workshop of golden gun new material company, which had been silent for more than half a month. A week later, the first-line workers of golden gun new material company have arrived more than 60%. "As of the end of February, we have received orders from more than 30 domestic and foreign enterprises for epidemic prevention products, with an order volume of more than 2000 tons of rubber." Cao Jianqiang said that if all these pur hot-melt adhesives are used to produce protective clothing, 30 million sets can be produced.
Pur hot melt adhesive, invisible hero in protective clothing
What is the secret of PUR hot melt adhesive in protective clothing? Why is the pur hot melt adhesive of golden gun new material company so popular? In the golden gun new material company, a protective suit was placed in front of the reporter. "From the outside, it's no different from the regular protective clothing. The secret lies between the non-woven fabric and the breathable film." Cao Jianqiang said.
Cao Jianqiang made an experiment for reporters. The protective clothing is placed on the waterproof and air permeability tester, and the air pump is pressed hard, a large number of bubbles come out, but the dripping water is not seeped. "This is a special fabric for protective clothing, which is impermeable and has good air permeability. Among them, PUR hot melt adhesive plays a crucial role. " Cao Jianqiang said.
Cao Jianqiang introduced that, generally speaking, the main fabric of protective clothing is non-woven fabric and breathable film, and pur hot-melt adhesive is an important material to closely fit the two. "Under the epidemic situation, the safety of protective clothing, especially medical protective clothing, is vital to life, and the quality of any kind of material is crucial." Cao Jianqiang said that medical personnel wear protective clothing and stay in a sealed space for a long time, which requires that the protective clothing must be able to effectively block liquids, droplets, bacteria, viruses, etc., and have good permeability and flexibility. The pur hot-melt adhesive produced by their company is a new nano technology material developed in cooperation with Suzhou Institute of nano technology, Chinese Academy of Sciences. The surface micropores formed by the composite of this material are one twentieth of the size of liquid water drops, and 700 times the size of water molecules. This "respirable material" is effectively combined with the other two materials, which can expel the gas volatilized from the wearer's body and effectively block the invasion of external substances.
In fact, in recent years, the pur hot melt adhesive of golden gun new material company has been widely welcomed, and its customers also cover many fields such as medical protection, assembly building, electronic components, automobile interior decoration, 5g communication, etc. In particular, several well-known outdoor clothing and down clothing manufacturers at home and abroad are long-term partners of golden gun new material company. "In the face of the epidemic, we have completely suspended the supply of medical protective clothing materials to cooperative manufacturers in fields other than protective materials, freeing up production capacity to fully supply raw materials for medical protective clothing." "We are confident that we will cooperate with the manufacturers of protective materials to win the battle of epidemic prevention and control," Cao said
Pay attention to product research and development, street run enterprises grow up big dream
Where does Cao Jianqiang's confidence come from? In the nano packaging materials laboratory of golden gun new materials company, reporters seem to have found the answer.
This is a research and development center with nearly one thousand square meters. Dozens of rooms are filled with various instruments. "Only high-quality R & D can produce high-quality products." Cao Jianqiang said his company has invested tens of millions of yuan in the research and development of new functional adhesives and insulating materials. As an unlisted private enterprise, these funds are squeezed out of the limited profits of the company. Cao Jianqiang introduced that the adhesive produced by them at present has the functions of flame retardant, anti-static, high temperature resistance, UV resistance, conductive and magnetic conductivity.
With excellent product quality, golden gun company has a great reputation in the adhesive industry. In fact, it has developed step by step from a small street factory.
The predecessor of golden gun new material company is Suzhou adhesive factory, which was established in 1988. The factory site is now the community office of Baibu street, Shuangta street, Gusu district. This is a welfare collective enterprise. Half of the workers are disabled. After graduating from University, Cao Jianqiang was assigned to work here. He majored in chemical engineering and engaged in what he liked. Cao Jianqiang started to do it as a career. As the head of the enterprise, relying on the spirit of research, he just developed the small factory with only 20 people to the current scale.
As novel coronavirus pneumonia is becoming more and more intense abroad, the new company is also protecting the supply of raw materials from many foreign protective materials manufacturers. "Just a few days ago, we supplied nearly 100 tons of PUR hot melt adhesive to a number of enterprises such as South Korea and Vietnam." Cao Jianqiang said.
Half a month ago, golden gun New Material Co., Ltd. was listed as a key epidemic prevention material support enterprise in Suzhou. Its product pur hot melt adhesive was rated as an innovative anti epidemic product, which made Cao Jianqiang further understand the importance of the industrial chain. "We are a private enterprise providing basic materials, but still an important part of the whole industrial chain." Cao Jianqiang said that there is no low-end industry, only low-end technology. As long as we are willing to work hard, even the humble products can make great contributions to the society at the critical moment.
