The safety protection of processors can be solved by liquefaction, paste and granulation of stabilizers. For the safety protection of users, the high molecular stabilizer can be quantified or reactive stabilizer can be prepared to improve its pumping resistance. However, considering that the stabilization is a molecular chemical reaction, the above method is not the most suitable, and the best method is to choose a high-safety stabilizer. When selecting stabilizers, we must also consider the safety of chemicals generated by the reaction between resin and stabilizers or stabilizers during the stabilization process.
