Film coated glass bead for screen and its processing technology

Abstract

A coated glass bead for the screen features that its particle diameter is 0.05-0.25 mm and its external surface is coated by a methyl silica oil film. Its advantages are high hydrophobicity, high adhesion to screen, high uniformity of arranging on screen surface, and low adsorption to dust.

Description

technical field [0001] The invention relates to a screen product, in particular to a glass bead screen product. Background technique [0002] In the production of the screen, the glass beads are implanted into the screen to increase the brightness coefficient of the screen, which greatly restores the effective color, making the screen image clear and vivid, and the color is beautiful and moving. However, in the actual production operation of the glass bead screen, the following problems occur: 1. When the glass beads are processed to no more than 80 mesh, it is very easy to absorb moisture and agglomerate. Especially in the area south of the Yangtze River, it is difficult to implant glass beads into the screen due to the frequent rain and fog days and the absorption of moisture by glass beads, which causes great difficulties in screen production. 2. The glass beads of the screen are uneven in particle size. In the production operation, the glass beads with a large weight en...

AI Technical Summary

Problems solved by technology

But in the actual production operation of the glass bead screen, the following problems occur: 1. When the glass beads are processed to no more than 80 mesh, it is very easy to absorb moisture and agglomerate

Especially in the south of the Yangtze River, due to rainy and foggy days, glass beads absorb moisture and other reasons, it is difficult to implant glass beads into the screen, which causes great difficulties for screen production

2. The particle size of screen glass beads is uneven. In the production operation, the heavy glass beads enter the cloth surface resin first, and the relatively light glass beads enter the cloth later, which often causes overlapping phenomenon of the cloth, which affects the mutual refraction of the glass beads and reduces the screen brightness factor

3. Because the screen made of glass beads is a strong polar base, it is very easy to absorb dust in the air, which is not easy to maintain and store

4. The bonding force between glass beads and screen resin is poor, and it is easy to fall off, which reduces the service life of the screen
