To produce medical PVC hard film, firstly, the main agent, curing agent and solution should be mixed and stored in a stainless steel barrel according to a certain proportion, and then fully stirred, then added to the coating head glue tank, and then use the corona treatment machine to change The liquid surface tension of the PVC hard film is applied to the coating head and the adhesive is applied, and then the adhesive is baked in a warm air drying tunnel; then the PE film is treated in the same way, and then the two are combined cooling and winding. Then the material rolls are stored at a temperature of 50-60℃ for 3-4 days, and then cut into various products with different specifications with a block machine.
The production of PVC/PVDC composite sheets usually chooses the reverse gravure coating process. Each step is basically the same as the first step above. It is also that the main agent, curing agent and solution are mixed according to the ratio and then added to the coating head glue tank. When making PVC emulsion, first add lubricant additives to PVDC emulsion, add PVDC center tank after stirring, and then use pump to drive into its coating head. Use a corona processor to change the liquid surface tension of the PVC hard film, then apply adhesive, use warm air to bake, roll coated PVDC, and then use warm air to remove moisture, bake, cool, and rewind. After applying several times until it exceeds the standard coating amount, the coated roll is cured at 50-60℃ for 3-4 days, and then cut into various products with different specifications.
In fact, in general, no matter what kind of process, we should pay more attention to it in production and use. Not all products have the same method in production and use. The production and packaging requirements of PVC sheets for medicine are required. It will be even higher. Clean and clean materials are a must. Do you need to order sheet products such as APET sheet, PVC sheet, GAG sheet, and ABS sheet? If you need it, call it!
