Amino moulding plastic granulating process

Abstract

The invention belongs to the field of plastic manufacturing and provides an amino moulding plastic granulating process. The process comprises the following steps: 1, squeezing, wherein amino moulding plastic is conveyed into a screw extruder through a feeding valve, and the amino moulding plastic is heated and squeezed into blocks through the screw extruder and conveyed into a rolling machine; 2, cooling, wherein the block amino moulding plastic is rolled into flakes through the rolling machine and then conveyed to a net belt, and then the flake amino moulding plastic enters into cooling equipment for being cooled; 3, grinding and prilling, wherein the cooled amino moulding plastic is output through a discharging valve and enters to a crushing machine for being prilled; 4, packaging, wherein the crushed and prilled particles are packaged after being screened through a screening machine. The amino moulding plastic particles manufactured through the method is stable in physical properties, the chemical volatiles are little, the fluidity is stable, and the amino moulding plastic can be maintain from 12 to 24 months and are not prone to being crushed.

Description

technical field [0001] The invention relates to a granulation process of amino molding compound. Background technique [0002] Amino molding compound (commonly known as electric jade powder) plays a very important role in the field of chemical materials, especially the production process of forming electric jade powder into granules is very important. The process of electric jade powder granulation mainly includes kneading, drying, cooling , crushing and packaging. At present, the kneading process of domestic electric jade powder granulation is mainly made of urea, formaldehyde, wood pulp, titanium dioxide and other raw materials through the kneading reaction of the reaction pot. The process of this kind of product is complicated and requires steam and reaction pot. The physical properties are unstable, there are many chemical volatiles, the fluidity is variable, and the shelf life is about 3-6 months; therefore, the lack of easy flow performance and strength of electric j...
