A Sudden Fire Broke Out During Film Printing!
Tongda Printing – Xiao Xu: While printing NY, a fire suddenly broke out. We later measured the coefficient of friction of the NY and it was over 0.9. Could that be the cause?
Yuncheng Plastics BOPA Xiao Yan: It was caused by high static electricity.
Hebei Taida CPP: Caused by static build-up from high friction.
Fulishi Solvent-free Adhesive: Was it during the lamination process that the fire broke out?
Tongda Printing – Xiao Xu: The fire broke out during printing, and also during lamination. Do you think it is related to the material?
Fulishi Solvent-free Adhesive: Do not laminate nylon on the Longhui machine; laminating on the Shanzhang machine can reduce this problem.
Zhejiang Printing: The static electricity is too strong.
Tongda Printing – Xiao Xu: Why?
Chunqiu: What color were you printing?
Tongda Printing – Xiao Xu: A white background, plus blue and gold.
New Oriental Yu Yongyue: This is a fire triggered by static electricity generated by the gold ink. You can change the ink or add an antistatic agent.
Tongda Printing – Xiao Xu: What is strange is that when we switched to another batch of nylon film, it did not happen. What I would like to ask is whether this batch of nylon film has a problem, because we have been using nylon film all along and have never had this situation before.
New Oriental Yu Yongyue: I have encountered a fire before, not when printing NY, but when printing large-area gold and silver color blocks on PET. I estimate it was caused by a large accumulation of static electricity on the NY and PET films.
Zhou Quan: Generally, dry weather in the north easily generates static electricity. Static electricity in the material also exists, but it can usually be dealt with.
Shangpin Color Printing Alan: Try installing a static bar to deal with it; it should be caused by static electricity.
