High temperature heat resistant tempered toughened 4mm glass

Advantages of Heat Resistant Glass

The main advantage of Heat Resistant glass is that it helps in insulation by reducing the heat gain and heat loss.    Adding multiple layers of glass with gas infill further protects the windows and building from heat loss.

Another advantage of Heat Resistant glass is that it increases the energy efficiency in buildings.    The reduced heat transfer lowers the electrical power consumption required for heating or cooling of the space.    This drastically cuts down the electrical bills especially in areas subjected to extreme heat or cold.    The use of low-e glass and reflective coatings can further improve the efficiency of the windows by further limiting the heat transfer.

Heat Resistant glass also helps in sound insulation and improves the acoustics of the place.      The inert gas present in between the two panes of glass does not allow noise to pass through and acts as a barrier  between the interiors of the building and the noise that is present outside the building .

*heat resistant glass can be made up of two or more sides.

* Each side can be made of different glass materials, such as laminated, tempered,coated glass.

* Each customization has different

characteristics to meet the different

needs of each customer, such as color style, strength or other performance.

Q:Plastic products in the classification of fire levels is how the standard ah?
Flammability UL94 grade is the most widely used standard for combustible properties of plastic materials. It is used to evaluate the ability of the material to be extinguished after being ignited. According to the burning speed gallbladder Ding book scratching calcium difference water to promote the alarm, burning time, anti-drop ability and drop beads can burn a variety of judging methods. Each test material can be a lot of values ??depending on color or thickness. When a material of a product is selected, its UL grade shall meet the thickness requirements of the wall part of the plastic part. UL grade should be reported along with the thickness value. It is not enough to report only UL grade without thickness. Plastic flame retardant grade by HB, V-2, V-1, to V-0 step by step increase. 1.HB: UL94 standard in the bottom of the flame retardant grade. Requires a sample with a burning rate of less than 40 mm per minute for samples of 3 to 13 mm; a sample less than 3 mm thick, a burning rate of less than 70 mm per minute; or extinguished at 100 mm mark. 2. V-2: After two 10 seconds of burning test, the flame was extinguished in 60 seconds and no burner could fall. 3.V-1: After two 10-second burn tests on the sample, the flame was extinguished in 60 seconds and no combustibles could fall. 4.V-0: After two 10-second burn tests on the sample, the flame is extinguished in 30 seconds and no combustibles can fall.
Q:What is the thickness of the thin fire retardant paint brushing each time?
Thin-type fire-resistant paint brushing or spraying the thickness of each 0.5-2mm, according to the nature of the material to determine the thickness. Thin fire retardant coating if it is the kind of wear and tear that the amount of more than the burden of consumption in Russia with the same thickness of the spray between the 1-1.5mm appropriate. Wait until the coating is dry and spray the next time, the thickness of the coating is not sag as the standard. First, the construction method 1, before the construction of steel surface to be rust treatment, and remove the surface dust, oil, spray 1 to 2 times the anti-rust paint. 2, with a bucket spray device with 0.4-0.6Mpa air pressure spray, paint to be evenly stirred. 3, pay attention to the first coating coating thickness of 1mm or so, dry and spray the second time, the coating thickness of 2mm, after drying spray the next time, and so on until the corresponding coating thickness. 4, according to the requirements of the fire limit level, spray to the appropriate coating thickness. 5, when the surface requirements of smooth and smooth, should be applied to the last side of the spray for smoothing. Third, the note 1, the coating can not be mixed with oily paint in the wet state. 2, the construction temperature should be above 0 ℃, rain or surface condensation or air humidity more than 85% when the construction should not be. 4, the paint is not combustible, not fried, non-dangerous goods, all kinds of transport can be transported.
Q:Decoration decoration materials, fire performance in line with the technical standards of fire how to apply for documents?
Supplier of the test report (a qualified inspection agency issued, preferably the National Fire Building Materials Quality Inspection and Supervision Center report), some places require on-site sampling, then, according to their flower lambs can be cut off the snow Grinding rules do it....
Q:What are the fireproof materials?
Inorganic binder: mainly water glass, gypsum, phosphate, cement, etc .; refractory mineral fillers: alumina, asbestos powder, calcium carbonate, perlite, white powder, etc .; flame retardant organic resin: Ethylene, perchlorethylene, chlorinated rubber, neoprene latex, epoxy resin, phenolic resin and the like. (Chlorinated paraffin, tributyl phosphate, decabromodiphenyl ether), and boron (boric acid, dibromide), boron, Zinc borate, aluminum borate), antimony, aluminum, zirconium and other inorganic compounds.
Q:Is the soundproof cotton a fireproof material?
There is fire, there is no fire.
Q:Is the material inside the fire door gypsum board?
Not gypsum board. General inside the material is the fire board, steel or cement board, to have a certain fire resistance, flame retardant, can be used as a fire inside the door
Q:Must be fireproof material!
Can not! That stuff is full of it! In the past, our company is the thing to engage in fire!
Q:Fire safety basic knowledge training content
What is the meaning of the signal disc valve action?
Q:Today, see the Christine plant more broken off the German vouchers fan of the CCTV news channel reported that the district energy-saving transformation, the workers are more tense, the first use is to meet the A-class thermal insulation materials, later said to be polyurethane insulation board, and then use the fire A little moment on the smoke, and quickly took the fire machine, then smoke did not burn out, repeated several times did not dare how, this insulation board really fire? More
China's national standard GB8624-97 will burn the performance of building materials are divided into the following grades A: non-flammable Building materials: almost no combustion of the material. B1 level: flame retardant building materials: flame retardant materials have a better flame retardant effect. In the air, there is no fire in the case of high temperature, it is not easy to spread quickly, and when the fire is removed, the burning stops immediately. B2 grade: flammable building materials: combustible materials have a certain role in flame retardant. In the air in case of fire or under high temperature will immediately fire burning, easy to lead to the spread of fire, such as wooden pillars, wooden truss, wooden beams, wooden stairs and so on. B3 level: flammable Building materials: no any flame retardant effect, easy to burn, fire risk is great. Polyurethane insulation board after flame retardant treatment up to B1 level.
Q:Fire-resistant coatings are generally water-based or oily
Common fire-resistant coatings on the market are also water-soluble (oily). Fire retardant coating from the dispersion medium can be divided into: water and solvent-based two. Water-based fire retardant coating: water as a dispersion medium, the emulsion for the film-forming material, in a variety of flame retardants, filler composition of water-based fire retardant coating. Solvent (oil) fire retardant coating: organic solvent for the thinner, resin for the film-forming material, in a variety of flame retardants, fill the composition of solvent-based fire retardant coating. The difference between the two: water-based fire retardant paint green, environmentally friendly fire-resistant coating, is the national and industry recommended species. Solvent-based fire retardant coating because of the organic film in the process of drying, benzene, xylene and other needs to be volatile, so people and the environment have a certain impact, but in a certain environment, solvent-based fire retardant coating fire resistance, water resistance Chemical resistance is water-based fire retardant coating can not reach. With the continuous progress of technology, the future may be completely eliminated solvent-based fire retardant coating.
