Auxiliary agent adding device and auxiliary agent adding process for polycarbonate

Abstract

The invention discloses an auxiliary agent adding device and an auxiliary agent adding process for polycarbonate, and can solve the technical problem of accelerating the melting of an additive while ensuring the quality of a polycarbonate product. The auxiliary agent adding device for the polycarbonate comprises a mixing and preparing tank, a liquid storage tank, a material pumping pump and a conveying pipe, the mixing and preparing tank, the liquid storage tank and the material pumping pump are sequentially connected through the conveying pipe, a feeding hopper is arranged at the top of the mixing and preparing tank, the material pumping pump is connected to a discharging opening of the mixing and preparing tank, a circulating pipe is connected between the mixing and preparing tank and the material pumping pump, a circulating pipe upper ball valve is installed on the circulating pipe, and a conveying pipe upper ball valve is installed on the conveying pipe between the material pumpingpump and the liquid storage tank. The auxiliary agent adding device is simple in structure, convenient to operate, low in production cost and capable of effectively improving the auxiliary agent mixing efficiency by being combined with ESO; and meanwhile, the temperature maintaining of the ESO and time are limited in the using method of the device, and the dissolving speed of the auxiliary agentis effectively increased, so that the quality and performance of polycarbonate product are well improved through the auxiliary agent.

Description

technical field [0001] The invention relates to the technical field of polycarbonate processing, in particular to a polycarbonate additive adding device and an adding process. Background technique [0002] The information disclosed in this background section is only intended to increase the understanding of the general background of the present invention, and is not necessarily taken as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to those skilled in the art. [0003] Polycarbonate is a high molecular polymer containing carbonate groups in the molecular chain. According to the structure of the ester group, it can be divided into aliphatic, aromatic, aliphatic-aromatic and other types. Polycarbonate plastic is a plastic with polycarbonate as the main component. Polycarbonate is an amorphous polymer that turns into a transparent glass after melting and cooling, with excellent optical and mechanical properties. It ha...

Problems solved by technology

[0004] During the processing of polycarbonate, some additives such as antioxidants, mold release agents, and toners are usually added during the melt extrusion process. These additives are directly added to the polycarbonate melt, which is difficult to disperse evenly and is easy to Caking, affecting product quality
