With the rapid growth of the soft drink market, more and more waste PET bottles have caused serious white pollution, which has aroused the attention of the community. The research objective of this project is to develop a superplastic super tough low-cost new material characterized by the strength
Read moreIn recent years, the coating of textbooks is basically using pre-coated films. As the use of time is not long, there are many problems, according to process practice shows that the quality of pre-coated film coating is mainly temperature and pressure. Three major factors of speed, so the correct h
Read moreIn our day-to-day work, we can often meet with the quality of the PS plate that has already started printing on the machine. Then we need to remove the PS plate from the printing press, reprint it, and repeat the printing process. Since the process includes the drying time of the printing plate an

The main reason is that the ink feeding system causes poor mutual solubility of wax surfactants, and the second reason is that the printing process is not reconstituted after the ink crust is transferred to the graphic. Treatment method: Aromatic hydrocarbons or ester solvents
