Example Embodiment

[0016] Referring to the accompanying drawings, a method for forming a non-planar polyurethane screen 1 includes the following steps:

[0017] a. Select high-strength polyurethane material, heat it to 140° in an oven, and perform dehumidification and dehumidification treatment. After the raw material is dried, it enters the blender, and at the same time, nanomaterials, fumed silica, and ultrafine toner are added to form a synthetic material. ;

[0018] b. Use 400-ton injection molding machine for secondary synthesis, built-in Tian-shaped frame, one-stage mold temperature is controlled at 203°, vacuum method is adopted, one stage is adjusted to control one stage, which is convenient for molding, the second-stage mold temperature is controlled at 180°, and the molding is The three-stage temperature is 100℃, 185℃ and 180℃ respectively; circulating water needs to be injected during demolding to keep the mould cavity set after the material enters.

[0019] c. After taking out the product,...

Abstract

The invention discloses a forming method of non-planar polyurethane screen meshes. The forming method of non-planar polyurethane screen meshes comprises the operation steps of a, selecting high-tenacity polyurethane material, heating the high-tenacity polyurethane material to 140 DEG C, removing humidity, drying raw material and feeding the raw material into a material fixer, adding nanometer materials, gas-phase silicon dioxide and ultrafine ink powder to commonly mix and form a synthetic material. According to the forming method of the non-planar polyurethane screen meshes, the aperture ratio is increased by 50% on the original basis; an isosceles triangle is arranged; holes are formed in two oblique sides; compared with a normal plane screen, the aperture ratio is increased by 50%; apertures are formed in two oblique sides; due to the principle that the water flows through screen holes from top to bottom, high screening efficiency is achieved; good dewatering effect is achieved, so that the holes are not blocked.

Description

technical field [0001] The invention relates to the fields of dehydration of various mine tailings and classification of artificial sand, and specifically belongs to a forming method of a non-planar polyurethane screen. Background technique [0002] The surface of the existing screen in my country is flat, the material flow speed is fast, the opening rate is low, the water content of the material is large during transportation, which affects the environment, the mineral classification does not meet the requirements, and the hole plugging phenomenon is serious. Contents of the invention [0003] The purpose of the present invention is to provide a method for forming non-planar polyurethane screens, which increases the opening rate by 50% on the original basis, sets up an isosceles triangle, and has holes on both hypotenuses, half of the openings than normal flat screens. The porosity is based on the principle that the pore diameter is produced on the two hypotenuses, an...
