Problems solved by technology

This granulation method needs to fix a motor position on the granulator, and the flexibility of equipment installation is poor
In the traditional process, the particles granulated by the granulator are directly fed, but at this time the particles have not been cooled and some organic waste gas is still volatilized
In addition, due to the fact t

Description

Technical field [0001] The invention relates to the field of polyamide preparation, in particular to a polyamide production system. Background technique [0002] Polyamide resin, PA for short, is a polymer with amide bonds in the main chain. It can be obtained by polycondensation of diamine and diacid, and ring-opening polymerization of lactam. Due to the different types of dibasic acid and diamine used, a variety of polyamide resins can be obtained. According to the relative molecular weight, it can be roughly divided into high molecular polyamide resin and low molecular polyamide resin. [0003] Macromolecular polyamide resin, known as nylon or polyamide, is composed of linear aliphatic diacids and diamines. It is mainly used to prepare synthetic fibers and engineering plastics. It has a relatively complete development and research process. . [0004] Low-molecular polyamide resin is obtained by polycondensation reaction of dimer acid and diamine or polyamine, also known as dim...
