5 factors that influence quality insulating glass

  Insulating glass is formed by the combination of two or three pieces of glass, between the glass and the glass desiccant, compared with single sheets of glass for insulating glass, has a higher level of security, but a single piece of glass replaced should damage the entire product.
  Since its used for insulating glass, its production has experienced double glass, a simple double-glass, hand-single channel seal, double seals and newly developed composite rubber Strip type insulating glass. After nearly 40 years of development, insulating glass market is maturing. Along with the emphasis on building energy efficiency, quality of the insulating glass has been receiving increasing attention. What are the factors affecting quality of insulating glass?
  insulating glass
  The current domesticInsulating glassThere are three main types: 1. channel aluminum type sealant 2. channel aluminum type double seal, 3. composite sealing strip type insulating glass.
  -Slot aluminum sealant, because of its poorly sealed, moisture, condensation lead glass, frosted, short life, so the kinds of insulating glass is gradually phased out. Two kinds of raw materials for insulating glass are: glass, aluminum, gusseted, butyl rubber, two-part polysulfide rubber or silicone Tong gel, desiccant, seal Strip.
  Following a small addendum to share with you a simple 5 elements affecting quality of insulating glass!
  , Selection of raw glass
  1. manufacture of raw glass insulating glass can be colourless float glass, coated glass, tempered glass, laminated glass, and so on. You should avoid using ordinary flat glass, ordinary flat glass are not up to the requirements of transparency and strength. Above the original glass plate must comply with the appropriate standard, qualified to use.
  2. different various batches of glass before cutting the first check there is no color.
  3. glass cutting dimensions, should be implemented strictly according to the drawings, and operations personnel should pay attention to the glass surface may not have obvious defects such as scratch, bubbles.
  Second, aluminum, gusseted selection
  1. aluminum thickness should be between 0.3-0.35mm, thickness should be uniform, vent holes evenly distributed. Aluminum Anodic oxidation treatment or decontamination must be bent, be sure to use good quality and high grade products. Raising the utilization ratio of aluminium.
  2. insert dimensions to choose the right surface to clean.
  Third, the use of desiccants
  Current use of insulating glass desiccant, there are three main types:
  1. volatiles absorption better;
  2. on the adsorption quantity of inert gases lowest;
  3. General molecular sieve.
  Users should select the appropriate molecular sieves to suit your needs, as well as molecular sieves should have suitable granularity (1-1.5mm) and hardness. In addition, using molecular sieve of the environment must be dry, fill the molecule should be used within 1.5 hours in order to ensure the quality of insulating glass.
  Selection of four, sealants
  1. butyl rubber
  Butyl rubber is Al-Insulating glassThe first seal, it is a hot-melt Adhesive, with low water vapor transmission rate (lowest in the insulating glass sealant) high viscosity, is aluminum sides and glass between the most effective barrier to water vapor, but it required a dedicated machine heating, pressing, extrusion coating on aluminum bars on both sides.
  More domestic rubber manufacturers, but the production of rubber, the heating temperature and pressure are not the same, some manufacturers of butyl rubber or even with a machine, often interrupted due to impurities. This requires the user to select good quality products, and clear understanding of the requirements.
  2. the polysulfide rubber
  Polysulfide rubber insulating glass sealant used is the largest one of polysulfide rubber has good oil resistance, refractoriness and tightness. Polysulfide rubber to metal oxide as a curing agent using aggregate, two-component ratio of approximately 1:10, proportion and the degree of influence on the effect of not too big, therefore glue machine can also hand painted.
  Polysulfide rubber selection requirements: two-component difference of pattern; maturity of more than six months; strong UV resistance, good liquidity and curing elastic.
  3. SI Tong plastic
  Chamber of Silicon sealant has a structural resistance, aging resistance and UV resistance, but its weakness is water vapor transmission rate high. Tong glue suitable for thus Silicon in strong light, bad places, such as glass curtain walls, must be sealed with butyl rubber the first road. Tong rubber silicon, in the past, my country's long dependence on imports is now leading group for State economic and Trade Commission has set up a Chamber of silicon glue, secure certification of structural adhesive. At present, there are many enterprises through the certification.
  Five, the use of composite sealing stripes
  Composite sealing tape is in the 1980 of the 20th century by the United States chemist who developed a sealing material. It is a supporting skeleton (wave-shaped aluminum Strip), seal (butyl rubber), dry (drying agent) in one of the raw materials for insulating glass, the biggest advantage is that the process is simple, less waste of raw materials, staff shortage, low management costs, operating environments well; shortcoming is the glue absorb moisture slowly, must have special equipment. Strip currently under production prices are higher, and selection of composite sealing stripes for, taking into account the smooth surface, strip quality, rubber content, viscosity, etc.
