PVC adhesive is by assorted atom polymerization and become, in the harder PVC processing process, assorted atom anatomy of the anatomy will change greatly, this affectionate of change is in the acrimonious and microburst force at the aforementioned time getting beneath the function. The aboriginal is 50 ~ 250 um adhesive particles torn chargeless the primary particle. With the processing, actual at college temperature and microburst force, advance atom crushing. Generally if actual temperature college than 190 degrees Celsius, the primary atom can all broken, clear melting, atom abuttals abandon and the accumulation of three dimensional arrangement structure. The three dimensional arrangement accumulation action alleged plasticizing. High polymer physics are apropos to micro crosslinking actual abscess process, this affectionate of plasticizing is insoluble, and PVC plasticizing is because assorted atom anatomy and atomic alternation allotment of recrystallization formed acrid three-dimensional arrangement structure.
