Production technology for bakelite powder and pre-thermoplastic machine thereof

Abstract

The invention discloses production technology for bakelite powder and a pre-thermoplastic machine thereof. The production technology comprises the steps of: mixing component raw materials, crushing the mixture into powder, stirring the powder uniformly, and adding the powder into an open type plastic purificating set for rubber mixing. The production technology is characterized by adding the powder which is stirred uniformly into a sealed pre-thermoplastic machine for preheating first to make the powder change into slightly fused particles and blocks, and then conveying the particles and blocks to the open type plastic purificating set for rubber mixing. The production technology and the pre-thermoplastic machine thereof effectively solve the problem that a conventional process has flying dust during the rubber mixing of the open type plastic purificating set further to seriously pollute the environment for a long time; and at the same time, the production technology makes a pre-thermoplastic working procedure of a powder raw material which is originally performed in a high-power open type plastic purificating set separated and performed in the pre-thermoplastic machine with a low-power sealing state in advance, which not only greatly reduces the production load of the high-power open type plastic purificating set, but also improves heat utilization rate and thermal efficiency, reduces production energy consumption, and improves production efficiency.

Description

technical field [0001] The invention relates to a bakelite powder production process and its preheating equipment. Background technique [0002] Bakelite powder, also known as bakelite powder, is a raw material for pressing or injection molding to produce insulation and heat insulation equipment. Its main components are wood powder, phenolic resin, calcium carbonate, mica powder, slaked lime, curing agent and pigment. At present, the production process of bakelite powder is generally as follows: first mix and crush the component raw materials into powder with a fineness of 120 mesh → mix evenly → add rubber to an open plastic refiner → cool and slice the colloid → further cool and then crush → Measuring, packaging. The biggest disadvantage of the above-mentioned traditional process is that when the powder with a fineness of about 120 mesh is directly added to the open plastic refining machine for rubber mixing, not only the dust will fly in the production workshop, the envi...
