Embodiment 1

[0016] This embodiment provides a method for planting sand for high wear-resistant abrasive cloth, comprising the following steps:

[0017] ⑴The base fabric is pulled through the glue tank filled with adhesive by the traction roller, and the base fabric is double-sided padded and glued. The absolute dry weight of the base fabric is less than 180g / ㎡;

[0018] (2) The glued base cloth passes through the high-voltage electrostatic field, and the speed of the base cloth passing through the high-voltage electrostatic field is V=ηE / (10d+1)H, where: η is the empirical coefficient, taking 0.75-0.83, and E is the electric field strength, taking 35000V / mA, d is the thickness of the base cloth 3mm, H is the distance between the two electrodes of the electrostatic field, take 250mm; add the abrasive into the electrostatic field from the upper and lower feeding ports in the direction of the entrance of the base cloth;

[0019] (3) Under the action of a high-voltage electrostatic field, th...

Abstract

The invention relates to a sand planting method for high wear-resistant abrasive cloth, which comprises the following steps: pulling the base cloth through a glue tank filled with adhesive through a traction roller, and performing double-sided padding and gluing on the base cloth; The glued base fabric passes through the high-voltage electrostatic field, and the abrasive is added into the electrostatic field from the upper and lower feeding ports of the base fabric's inlet direction; the abrasive in the upper and lower directions is under the action of the high-voltage electrostatic field, and the two sides are implanted with adhesive coating. The base cloth of the agent; the base cloth after sand planting is dried and cured, rolled and cut to form a finished product. Compared with ordinary abrasive cloth, the abrasive cloth made by the process of the present invention has the characteristics of good grinding performance, no embedded grinding debris, double-sided grinding, high grinding efficiency and long service life, etc., and is suitable for metal and non-metal surfaces. Grinding, derusting, grinding, polishing, etc., have a wide range of uses in many industries and fields such as construction, decoration, machinery, automobiles, and light industry.

Description

technical field [0001] The invention relates to a sand planting method, in particular to a sand planting method for high wear-resistant abrasive cloth. Background technique [0002] At present, abrasive cloth abrasives have been widely used in automobiles, machinery, aerospace, chemical industry, building materials and other industrial fields. Grinding, fine grinding, polishing. Compared with bonded abrasives, abrasive cloth abrasives can be folded, bent, wound, torn or cut into strips, blocks and other shapes, easy to use, can meet different processing requirements, suitable for large areas and complex Surface processing has characteristics that cannot be replaced by other bonded abrasives. However, abrasive cloth abrasives still have many disadvantages, such as poor flexibility, poor water resistance, and easy sand loss. Contents of the invention [0003] The technical problem to be solved by the present invention is to propose a sand planting method for high wear-res...
