The process and procedures in the Hollow glass production

Date：2013-10-24 Author：zhaoyang Hits：982

At present, the production of insulating glass, there are two ways: double sealed aluminum groove type and strip type (Swwiggle) where double sealed aluminum groove type accounted for 80% of the production process, tape-style production process accounted for about 20%. Aluminum groove type insulating glass production process, the use of equipment and techniques aluminum groove type insulating glass process and the use of equipment configuration: glass washing machines, plate press, butyl rubber machine, two component sealant machine, molecular sieve filling machine .

According to the user's requirements and design requested by the user according to the user's design, including size requirements, specifications, structural requirements, quality and other requirements accordingly, reasonable design. By user Designers are hollow glass production process before the procedure and the important part.

Design is mainly based, GB1194-89 "insulating glass" standards and some industry provides empirical data.
The main contents include: glass size, specification design, aluminum spacer feet kept, specification design, sealing materials requirements.

Glass cutting glass cutting cutting cutting the entire piece of glass is designed according to user requirements specific size cut type.

During the cutting process, to grasp the following technical requirements: to be accurate, error GB11944 - 89 "insulating glass" within the range specified; cutting line size to be uniform, in the process of cutting depth of the cutting line width must be consistent; fold waves institutions should reliable, folding wave off wave mandrel axis coincides with glass cutting lines to ensure that fold waves, the glass surface and the glass segment perpendicular to the plane, and the segments appear before a giant, flatness is better to lay a good foundation for the edging.

Glass, beveled glass edging role mainly two: the glass edge sharp, sharp edges down blunt; edge of the glass edge to eliminate stress. Glass edging mostly using soft grinding belt, so the grinding belt longer life, but need special attention to the ends of the middle ground by the grinding of glass, do not enter the belt at one end, so as not to cut through the belt .

Cleaning and drying of technical points:
1 according to the different regions, different water quality determines whether the rinse water to soften.
(2) cleaning water is usually recycled, so there must be a good filter.
3 air knife drying is preferably provided two, the second on the glass to dry after washing, especially in the second air knife use heat to dry air has a temperature of about 50 ℃, one purpose of improving the drying efficiency; Second easy to find the residue on the glass and crystal point.
4 Clean the drying process, the contact with the glass guide roller, roller, gutter, etc. to be resistant to aging, not fade, so as not to affect the quality of the glass.
5 aluminum spacer bar cutting aluminum spacer cutting pay attention to two aspects:
6 sizes of materials to be accurate (typically cutting device has length) 7. Spacer bar cutting section and tidy, no burr;
8 Do not damage the original cross-sectional size spacer for subsequent use.

Coated with the sealant coated insulating glass sealant is a product of the last step, the main purpose is to increase the sealing and bonding between the glass, the traditional two-component polysulfide sealant, because of environmental and cost aspects reasons, is launching a new sealant - hot melt adhesive, the combined effect is more ideal for two-component polysulfide rubber technical points: A, B component composition should meet the relevant standards; A, B component in -7:1 ~ adjusting the mixing ratio between 14:1; A, B component should be well mixed; has good curing, sealing and overall performance; gluing accuracy, no less plastic and more plastic phenomenon

For hot melt Techniques: spacer frame and the glass should be positioned accurately, and have pressed a fixed function; gluing section for demanding too much to increase the cost, too little sealing performance is not enough.
