Vacuum system used in UV glue bubbles and syneresis _

UV glue bubbles and dehydration shrinkage often affect product performance. In actual production and use of the UV glue, and some of the more thick the UV glue ( Viscosity is more than more than 20000 cp) Sometimes the syneresis. After syneresis macromolecular solution or sol gel, the structure of the gel formation and development continues. With a continuation of the time, the colloidal particles or molecules will further close to and directed more completely, so that the gel skeleton contraction, part of the liquid separated from the gel, called syneresis or from pulp. Use of air bubbles in the vacuum system to solve the UV glue deaeration and dehydration shrinkage.

deaeration is a process of solution spinning production, the purpose is to remove before spinning dope containing bubbles and can be carried out as normal and to ensure that subsequent spinning process. Vacuum systems has the following advantages:

1. Reduce the noise in the factory

2. Avoid wasting power

3. Portable system, flexible installation, take up less space

4. Full automatic control, add a certain amount of surplus, reduce downtime due to equipment's influence on the production

5. Convenient operation, high stability and reliability.

because it has so many advantages, so each is widely used in fields, such as electronic industry, glass processing, CNC engraving, mechanical manufacturing, the CD industry, semiconductor industry, vacuum deaeration, vacuum, vacuum fixed clamp, vacuum adsorption, etc.

deaeration three main factors, time, temperature and pressure.

temperature heating: 1. Increase the viscosity of glue, 2. Accelerate the glue liquid, 3. Increase the moist degree

pressure pressure: 1. Accelerate the flow of glue, 2. Increase the moist degree, 3. Pressure to remove air bubbles

time: 1. The glue continue flow, 2. Catalytic into phenomenon to remove air bubbles

use the pressure decreases, the volume of air bubbles, floating to the surface broken.

vacuum system in the application of UV glue deaeration can solve the problems of the traditional mixing equipment cannot solve, make of different components of the slurry, powder mixing fully, no separation, no bubble, high efficiency, the processing time is 3 minutes at a time. To meet the requirements of the mixing process and the high quality.
