Amino molding plastic granulation apparatus and process based on apparatus

Abstract

The invention relates to an amino molding plastic granulation apparatus and a process based on the apparatus. The apparatus used for preparing an amino molding plastic particle comprises a screw extruder, a rolling mill, a cooling device, a crusher, a feed valve and a discharge valve, wherein the feed valve is fixedly arranged at the input port of the screw extruder in the manner of sealing connection, the output port of the screw extruder is fixedly connected with the input port of the rolling mill, the output port of the rolling mill is connected with the cooling device through a mesh belt, the discharge valve is fixedly connected with the output port of the cooling device, the crusher is arranged below the discharge valve, and the input port of the crusher corresponds to the discharge valve. The process based on the apparatus comprises the following steps: extrusion; cooling; crushing; and packaging. The amino molding plastic particle prepared by using the apparatus has stable physical properties, a few chemical volatile matters and stable fluidity, can be maintained for about 12 to 24 months and hardly breaks.

Description

technical field [0001] The invention relates to a granulation equipment for amino molding compound, which includes a screw extruder, a roller machine, a drying device, a cooling device, a feed valve and a discharge valve. [0002] The invention also relates to a granulation process of amino molding compound, which includes the steps of extruding, drying, cooling and pulverizing. Background technique [0003] 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 ...

[0003] 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 and its equipment urgently need to appear
