Viskoziteni olishning ikkita asosiy usuli mavjudcho'zilgan plyonka:
1. Add PIB to the polymer
2. VIDPE bilan aralashtirilgan, yopishqoqlik biroz yomonroq
Why is the stickiness of the stretch film not so great when it is cold in winter? This is because it generally takes three days for PIB to move out, and it is also affected by temperature. When the temperature is high, the viscosity is strong; when the temperature is low, it is not too sticky, and the viscosity is greatly reduced after stretching. Therefore, the finished film is best stored within a certain temperature range (recommended storage temperature is 15 ℃ ~ 25 ℃).
Agar harorat biroz yuqoriroq bo'lsa, yopishqoqlik kuchliroq bo'ladi, shuning uchun biz uni saqlaganimizda haroratga e'tibor berishimiz kerak.
