Abstract

The invention relates to a method for manufacturing abrasive nylon brush filaments and its extrusion equipment. The invention solves the problem that the production equipment is easily damaged in the process of producing abrasive nylon brush filaments, and the production efficiency of the prior art is low and the time is long and low yield problems. The invention improves the extruding equipment, changing from one feeding hopper to two feeding hoppers. Its manufacturing method is to adopt the continuous production process of online shaping, use nylon 610 or nylon 1010 as the base material, choose silicon carbide or aluminum oxide with a particle size range of 100-1000 mesh as the abrasive, soak it with a silane coupling agent, and dry it. Then it is mixed with nylon according to the proportion of 20-30% of the total weight, and is fed by separate and independent feeding method, plasticized, melted, extruded, drawn, shaped, recycled and packaged as a finished product.

Description

technical field [0001] The invention relates to a method for manufacturing abrasive nylon brush filaments and extrusion equipment thereof. Background technique [0002] At present, when producing abrasive nylon brush filaments at home and abroad, the production equipment is very vulnerable to serious damage, resulting in great waste and greatly increasing the production cost. Due to the conventional blending feeding method, the abrasive powder is directly dry-frictioned with the screw barrel, and the screw barrel is extremely susceptible to wear. Generally, the screw barrel of the extruder must be replaced for the production of 1 ton of abrasive nylon brush products. set. In addition, the production efficiency is very low, the production time is long, and the output is also very low, and the conventional method can only use intermittent production, resulting in extremely low production efficiency. Generally, the production is counted at 6kg / h, and after producing about 150k...
