There are two main styles of hollow glass: trough aluminum insulating glass and rubber strip insulating glass. Because two kinds of insulating glass in the process of many similarities, now on their common process analysis.

1. From the aspect of raw materials, glass cutting:

Hollow original glass is generally colorless float glass or other colored glass, sunshade glass, quartz glass, tempered glass, laminated glass, the thickness is generally 3-12MM, the glass must meet the provisions of various national standards, after passing the inspection can be used. Glass cutting can be done by hand or by machine, but it should be guaranteed to meet the size requirements. This process workers in the process of operation, should always pay attention to the glass surface should not have scratches, homogeneous endoplasm, should not have bubbles, slag and other obvious defects.

2. From the glass cleaning and drying:

Hollow glass cleaning must use machine cleaning method, because manual cleaning can not ensure the quality of cleaning. It is necessary to check the glass without scratches before cleaning. In order to ensure the adhesion of sealant and glass, it is best to use deionized water. In addition, in order to ensure the recycling of water and save water resources, the water can be filtered to ensure long-term use. After cleaning, the glass should be inspected by light to check whether there are water beads, water stains and other stains on the surface of the glass. If there are water beads, water stains and other stains, it is necessary to adjust the running speed of the machine, heating temperature, air volume and brush clearance until the effect is intact. After washing the glass should be assembled into hollow glass within 1 hour, in addition to ensure that there is no friction between the glass and the glass, it is best to have semi-finished glass storage car, the glass between the pieces.
