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

Embodiment Construction

[0016] Below in conjunction with accompanying drawing, the present invention is described in further detail:

[0017] see figure 1 As shown, the following process is used to coat the surface of glass beads:

[0018] (1) Screening to remove impurities: select qualified glass beads with a sieve with a mesh number of 80, so that the particle size of the glass beads is between 0.05mm-0.25mm.

[0019] (2) Preparation of drugs: silane coupling agent uses methyl silicone oil. Put the methyl silicone oil with a viscosity of 50S and the sodium silicate with a concentration of 5% into the closed medicine tank of the coating machine equipment respectively, adjust the flow of the two liquids, the flow of the methyl silicone oil is 1 drop / 10 seconds, the silicon The flow rate of sodium nitrate is 1 drop / 20 seconds, drop into the container in the coating machine, and mix the two liquids together.

[0020] (3) Heating: heat the container, and control the temperature at about 50°C±2.

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 screen production, glass beads are implanted into the screen to increase the brightness coefficient of the screen, greatly restore the effective color, and make the screen image clear and lifelike, and the color beautiful and moving. But in the actual production operation of the glass bead screen, the following problems occur: 1. When the glass bead is processed to be no more than 80 mesh, it is very easy to absorb moisture and agglomerate. Especially in the area 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 in 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 relativ...
