A kind of granulation process of amino molding compound granules

Abstract

Prilling process of an amino molding plastic particles, comprises the following steps of a. extruding, placing amino molding plastics into the screw extruder through the feed valve to be heated, extruded into blocks, and transported into the roller machine; b. cooling, rolling blocks of amino molding plastics into sheets by the roller machine to be transported to the net belt and removed into the cooling device for cooling; c. crushing, removing the cooled amino molding plastics from the discharging valve into the crusher for crushing into particles; d. packaging, sieving the crushed particles through the screening machine for batch packaging. The amino molding plastic particles produced by the invention have stable physical properties, few chemical volatiles and stable liquidity, which are quite durable to be maintained for 12 to 24 months.

Description

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

[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 jade powder granulation urgently needs to be improved. A new electric jade powder granulation Technology, especially a new type of kneading technology urgently needs to appear
