evelopment and Situation of hollow glass insulating glass is made between two or more layers of glass supported by pitch has to be separated from the surrounding sealed space formed by the drying gas glass , Insulating Glass Production Machine important as a building outside the maintenance of the structure - - doors and windows of the main components of other products have unmatched features:
1.Excellent insulation properties , the thermal conductivity coefficient K value of less than 0.3 .
2.Sound insulation performance, to reduce the noise 30 ~ 50clb,
3.Since the hollow space inside the glass is dry gas or inert gas permeable its superior performance , and coupled with the inner space of decoration , the style has a variety of decorative properties ,
Large temperature difference between inside and outside in winter , the inner glass, no frost , no condensation . Since the 1980s , China has experienced a hollow glass in understanding , development and wide application of three processes , in the late 1980s, China began to introduce hollow glass , manufacturers relatively small , mostly concentrated in the production of state-owned enterprises , mainly used for refrigerator, aluminum doors and windows industry , the use of regional only in the Northeast, North and South freezer supporting materials manufacturers, the annual usage of less than 1 million m2, 90 years later, the Asian Games project driven , more important is the rapid development of the national economy , increasing demands for energy efficiency in buildings high, with aluminum curtain wall industry extraordinary development , the insulating Glass Production Machine into the development stage, but also led to the production of raw materials used in the development of hollow glass , raw materials are basically achieve localization .
Domestic production of hollow glass equipment also developed into orbit , but the main automation hollow glass equipment is still imported mainly to the mostly single-channel sealing , insulating glass annual usage 200m2 years or so, but to 1,000,000 m2 / year rate of increase ; the late 1990s along with the advantages of insulating glass has been growing awareness , acceptance , and promoting the development of plastic doors and windows , insulating glass into widespread application stage , hollow glass into the system within the building energy efficiency standards , many local governments to develop local regulations, require construction of insulating glass windows and doors must be used around the country set off a wave of investment in the production of insulating glass . According to incomplete statistics , the current production of insulating glass manufacturer is not less than 1000 , domestic and imported automatic production line of not less than 500 , the annual production capacity of not less than 10 million m2, according to statistics in 2002 IG about 25 million use m2, the great development of the hollow glass , insulating glass production process appeared diversification strip hollow glass because of its low investment , simple process, in the middle and low insulating glass market has around 20% market share .
Hollow glass production process and procedures
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 Production Machine process and use of equipment configuration: glass washing machines, plate press, butyl rubber machine, two component sealant machine , molecular sieve filling machine, the fundamental role of various processes and techniques
1.according to the user's requirements and design required 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.
2. design is mainly based , GB1194-89 " insulating glass " standards and some industry provides empirical data .
3. main contents include: glass size , specification design, aluminum spacer feet kept ,
specification design, sealing materials requirements.
4.glass cutting material is the whole piece of glass designed according to user requirements specific size cut type, in the cutting process, we should grasp the following technical requirements:
(1)1to be exact , the error in GB11944 - 89 "Insulating Glass Production Machine" within the range specified ; cutting line size to be uniform, in the process of cutting depth of the cutting line width must be consistent ;
(2)fold wave institutions are reliable , folding wave off wave mandrel axis coincides with glass cutting lines to ensure that fold waves , the glass
(3)segment perpendicular to the plane surface of the glass , and the segments appear before a giant , flatness is better to lay a good foundation for the edging .
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 : Ingredients should meet the relevant standards ; component can -7:1 ~ 14:1 between adjusting the mixing ratio ; 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. |
