② dry mixed: the PVC heat stabilizer for window synthetic resin powder in plasticizer, at a temperature under stirring conditions, to obtain the appearance of a synthetic resin with no significant difference between the original dry blend powder.
③ Glue: the fine-particle synthetic resin of adequate shear blender mixed plasticizer, the formation of stable and pouring the paste or slurry (see plastisol processing).
④ as a solution: the Glycerol monostearate synthetic resin is dissolved in a suitable solvent (or solvent mixture), and then mixed with a plasticizer to adjust solubility, i.e. a solution of synthetic resin plasticizer. Top 3 Ways need to be heated and stirred, the first four methods without heating.
Since a large amount of plasticizer, variety, plasticizer production technology tends to two aspects of development. On the one hand is the primary plasticizer continuous large-scale production; hand is a special plasticizers many varieties, small batch batch production.
With the increase of PVC production and petrochemical industry, has developed into a plasticizer to petrochemical-based, phthalate-based products, large-scale production chemical industry. Phthalate plasticizer production accounted for more than 80% for large-scale continuous production provided the conditions. Because many varieties, small batch plasticizer existence of the "universal" batch production plant that Acrylic processing aid is necessary for the survival of its development still.
To reduce the product color, thermal stability and improve the product further simplify processes, non-acidic catalysts have been industrialized. Use of non-acidic catalysts are less side reaction, the product color light, simple and refined products, produce less waste water quality is good, good thermal stability, product yield advantages.
