What is the tempered glass? What is the difference with ordinary glass?
Tempered glass is actually a kind of prestressed glass, in order to improve the strength of the glass, usually using chemical or physical methods (physical means that the wind quenching, the current building glass are used in this method) in the glass surface to form compressive stress, glass bear external force When the first to offset the surface stress, thereby enhancing the carrying capacity, improve the glass tensile strength. The main advantages of tempered glass are two, the first is the strength of several times higher than the ordinary glass, bending strength is 3 to 5 times the ordinary glass, the impact strength is 5 to 10 times the normal glass to improve the strength at the same time also increased The security. The use of safety is the second major advantage of tempered glass, its increased carrying capacity to improve the fragile nature, even if the destruction of tempered glass was no small angle of the small pieces of damage to the human body greatly reduced. Tempered quenching and cooling properties of tempered glass than ordinary glass has 2 to 3 times the increase, generally can withstand more than 150 ℃ temperature difference, to prevent the thermal cracking has a significant effect. From the appearance of the general do not see how much different with ordinary glass, but through the polarized sunglasses can be seen on the tempered glass with rainbow plaque - some of the old micro-van front can also be seen, this is tempered glass The unique phenomenon.
I need an answer by thursday morning 7 am
Depends on the size. The glass pyramid over the Louvre cost millions. On the other hand, you could build one the size of your head for about five bucks. A glass pyramid the size of those in Egypt would cost tens of millions. What did you have in mind?
Is there a way to reduce the noise
Multi-layer composite laminated glass sound insulation effect 25 - 45 dB, the market price of about 350 --- 800 yuan / square meter Multi-layer composite laminated glass is a combination of hollow and laminated glass, this combination structure, by China's most authoritative sound insulation acoustic testing institutions - Tsinghua University Building Environmental Testing Center made a comparative test shows that multi-layer composite laminated glass is the most sound insulation performance A good combination of the structure, in the actual installation and use, such as the main road traffic, high roadside, large overpass next to the room can reach the quiet level close to the basement, this glass also has thermal insulation, energy saving Consumption, anti-theft and other functions, this is both economical and easy to expand production of noise and noise reduction glass, is vigorously for the country to promote the application of the installation of noise windows [noise glass] to become a necessary choice to ease the city noise to us The distress caused.
Would you like to make windows white glass is good or green is good? That expensive Looks upscale? Thank you!
Tempered glass Tempered glass, also known as tempered glass, is heated to a certain temperature after the rapid cooling method, or chemical methods for special treatment of glass. Tempered glass is characterized by high strength, tempered glass bending strength, impact resistance than ordinary flat glass 3 to 5 times higher. Safety performance, there is a uniform internal stress, broken network was cracked. Mainly used for doors and windows, partition walls and cabinet doors. Tempered glass is still resistant to acid and alkali. The general thickness is 2-5 mm. Its size is 400 mm x 900 mm, 500 mm x 1200 mm.
maybe 1/2 inch or 1/4 inch and 5 feet length, 2 or 2 1/2 feet height, and 2 feet width. I can't really find any pricing on websites so I came here.
Call a glass shop--in the yellow pages under "glass" and ask them. You haven't given enough detail for anyone here to be able to tell you, even if we did know what prices are in your area.
glass inside the house water flowing on top of it and more glass over it,would it stop all radiation from the sun just by using water.
Glass doesn't filter all radiation. It may filter out SOME UV, but not all of it - otherwise the plants inside wouldn't last long. If you can see through glass - it is passing the range of electromagnetic radiation that out eyes are sensitive to - ie: visible light. It will also pass most other common forms of radiation α (alpha) - penetrates only a few inches in air β (beta) - penetrates perhaps up to 10 feet in air γ (gamma) - stopped only by extremely dense matter (at least 3 inches of lead or gold) cosmic rays - nothing on this planet will stop this - they pass through everything
Is the car 's annual inspection posted directly on the glass and can affix the solar film?
First affixed to the sun film in the paste year mark
Insulation glass 3C certification to investigate what time to start
China's State Administration of Supervision, Inspection and Quarantine and the State Certification and Accreditation Administration Committee on December 3, 2001 together issued a "mandatory product certification management regulations", included in the list of 19 categories of 132 kinds of products, "unified directory, unified standards And the assessment procedures, unified signs and uniform charges "mandatory certification management. 3C "certification from May 1, 2003 (later postponed to August 1) from the full implementation. Safety glass belongs to the first batch of products
