Q1: How to judge the quality of float glass? A1: Flatness, transparency, colorless, impurities, bubbles, etc. Q2: How to reduce the self-implosion? A2: The high quality float method is used for hot dip treatment, edge treatment and proper stress intensity. Pay attention to avoid side collision of glass during installation. Q3: Scope of use of toughened glass? A3: Safety is not involved in some parts of the building, but it is necessary to install toughened glass to improve the compressive strength and explosion-proof capacity,not to endanger the person safety Q4: When toughened glass is broken, is the grain smaller the better? A4: No, the smaller the particle, the easier it is to explode. Q5: Can toughened glass and semi-toughened glass be made into laminated glass? A5: Can't. The national standard stipulates: the glass that stresses the difference cannot make laminated glass, because in use process, the pressure that two pieces of glass bears is different. Q6: Whether the laminated glass can fire, can the sound insulation? A6: No, the smaller the particle, the easier it is to explode. Q7: How many uv low-e glass can reduce? A7: It is not fireproof glass, but has certain fireproof ability, also can soundproof, laminated glass is inside whole sound wave frequency range, in control noise is very good. Q8: Does the air in the insulating glass do not oxidize the membrane? A8: No, because there is a molecular sieve in the insulating glass, and the molecular sieve always keeps the air dry, so the membrane is not oxidized. Q9: How much ultraviolet radiation can low-e glass reduce? A9: It can reduce uv by 14% compared to heat reflecting glass. That's a 25 percent reduction in uv radiation compared to white glass.
