Problems solved by technology

[0002] High-mesh precision screens are currently only developed by companies in a few developed countries such as Switzerland. Due to the high manufacturing precision, high technical difficulty, and the wire diameter of the raw materials used is one-third of that of a hair, it often occurs during the trial production of the screen. Technical problems such as thin wire and easy breakage

Embodiment Construction

[0011] The present invention will be further described below in conjunction with embodiment.

[0012] A post-treatment process for a precision high-mesh screen with more than 300 meshes, the material is 100% nylon or 100% polyester, and the process steps are as follows:

[0013] (1) Cleaning treatment: Cleaning treatment is used to remove the grease and attachments of the product.

[0014] The specific steps are as follows: ① Warm water immersion screen: enter warm water into the tank, the water temperature is 60 ℃, the weight is 250 kg, and wash the screen twice with warm water; ② Out of water; ③ Hot water immersion screen: use hot water immersion screen , the water temperature is 95-100°C, the weight is 250 kg, and 3 kg of detergent and 0.3 kg of penetrant are added to the hot water, wherein the detergent is N-N-oleoylmethyl taurate sodium colloidal liquid, and the penetrant is The condensate of 35% ethylene oxide and 65% high-carbon fatty alcohol, the high-carbon fatty alc...

Abstract

The invention relates to a post-treatment process of a screen, in particular to a post-treatment process of a precise multi-mesh screen with more than 300 meshes, which comprises the following steps: cleaning treatment, water-proof treatment and forming and tentering treatment. Compared with the prior art, the invention solves the problems of degreasing, impurity removing and the like in the processes of trial-manufacture and use of the screen, and the screen after post-treatment has consistent tension in longitudinal and latitudinal directions, ensures the excellent dimensional stability of products and improves the bonding force of the products and the penetrability of ink.

Description

[technical field] [0001] The invention relates to a screen post-treatment process, in particular to a post-treatment process for a precision high-mesh screen with more than 300 meshes. [Background technique] [0002] High-mesh precision screens are currently only developed by companies in a few developed countries such as Switzerland. Due to the high manufacturing precision, high technical difficulty, and the wire diameter of the raw materials used is one-third of that of a hair, it often occurs during the trial production of the screen. Technical problems such as thin wire and easy breakage. There are not many domestic companies involved in this field, but with the electronic communication, medical and health, chemical and environmental protection industries, the demand for this product is increasing. As the leading company in the domestic screen industry, it should be the first to develop this type of screen Products, to fill the domestic gap, and enter the international ...
