Flat/curved laminated glass, which is in two pieces of glass between into a layer with polyvinyl butyral as the main component of the middle PVB film. Glass even cataclastic, debris will be glued to the film, broken glass surface is still maintain clean and smooth. It is effectively prevent the debris pierced through injury and fall incident, ensure the personal safety. In Europe and the United States, most of the buildings glass is used sandwich glass, this not only to avoid harm accident, but also because the sandwich glass has excellent aseismic invasion ability. Intermediate film can resist a hammer, chopped wood knife and weapon continuous attack, still can be in a quite long time period against the bullet through, the degree of security is extremely high.

Solid potassium tertbutoxide is white or kind of white Solid powder. Density 0.929, melting point 256-258 ℃, boiling point 275 ℃, reaction with water. Tertiary butyl alcohol potassium alkaline strong and nucleophilicity relatively weak, soluble in THF, often used for halogenated hydrocarbon dehydrohalogenation reaction. This product is organic alkaline corrosion products, strong absorption of moisture, should be sealed preservation, good shipping in the note fire, sunscreen and should be stored in a cool dry place ventilation. Can squeeze dry. Solid potassium tertbutoxide easily absorb moisture. Soluble in tertiary butyl alcohol, often used for halogenated hydrocarbon dehydrohalogenation reaction, and its solution is stable. Exposure to the air decomposition. In water is decomposed into potassium hydroxide and tertiary butyl alcohol. By tertiary butyl alcohol and potassium metal reaction, decompression evaporation to tertiary butyl alcohol system. Strong alkaline condensing agent, its basic a methanol sodium, sodium ethylate strong. Widely used in organic synthesis of condensation, rearrangement and ring opening reaction, general use a tertiary butyl alcohol solution. Solid potassium tertbutoxide risk properties: 4.1 class for flammable Solid, spontaneous combustion items and meet wet flammable items. More about: Solid potassium tertbutoxide suppliers

Coating glass also known as reflective glass. Glass in the glass surface coated with one layer or multilayer of metal, alloy or metallic compound film, so as to change the optical properties of glass, to meet special requirement. Coated glass products according to the different characteristics, can be divided into the following categories: heat reflective glass, Low-E glass ( Low-E ), conductive film glass.

Caustic Calcined Magnesite Block is a chemical composition of MgCO3, crystal belongs to the three party system of carbonate minerals. Often, Youtie manganese substitute for magnesium, but natural magnesite iron is generally not high. In 1960, China found west of the stone is a kind of Ni content as high as 29.64% magnesite variants. Magnesite is usually crystalline granular or cryptocrystalline dense block, which is also known as porcelain shape magnesite. White or off-white, iron yellow to brown, shiny glass. With perfect rhombohedral cleavage, porcelain shape magnesite with conchoidal fracture. Moss hardness of 3.5 ~ 4.5, 2.9 ~ 3.1 proportion. Caustic Calcined Magnesite Block is a magnesium carbonate minerals, it is the major source of magnesium. Containing magnesium solution on calcite, will make the calcite into magnesite, therefore also belong to the calcite magnesite. Magnesium rich rock will change into magnesite. Magnesite often contains iron, the iron or manganese magnesium replaced the results. Magnesite white or grayish white, shiny glass, iron magnesite will show a yellow to brown. If the show is granular crystal, if not show crystal is block. Magnesite except for refining magnesium, also can be used as refractory material and preparation of magnesium compounds.

Sandwich laminated glass rupture, in heavy ball impact may be broken, but one glass remained, fragments and sharp and small debris still stick together with the middle membrane. This glass is broken, fragment not dispersed, used in automotive and other traffic tools. Tempered glass impact force to require larger broken, once broken, one-piece glass burst into numerous tiny particles, only some broken glass frame. Ordinary glass a bump is broken, the broken situation of typical, produce many long sharp mouth pieces. Wire broken glass, mirror tooth fragments surrounded by a hole, and in the penetrating point around have more pieces of glass, metal wire fracture length. Discussion on the safety glass safety glass what is? It is in line with national standards of laminated glass, tempered glass, and they produced by the hollow glass, especially the laminated glass and laminated glass hollow glass for the best performance of the integrated. General civil tempered glass is the glass by heat treatment process, make its strength was increased by 3 - 5 times, can withstand a certain degree of energy external impact or temperature changes and do not break, even if broken, is also the whole glass broken into small particles resembling honeycomb obtuse, without hurting people, and have a certain security. Tempered glass can not be cut, need before tempering cut size, and " explode " characteristics. According to different purposes, tempered glass can be divided into full toughened glass, half toughened glass, regional toughened glass, tempered glass, curved tempered glass and other types of. Laminated glass as a kind of safety glass under impact crusher, due to its two common glass sandwiched PVB film bonding, not like ordinary glass broken after the sharp fragments. At the same time, it 's PVB film with sound insulation, solar control properties have made with energy saving, environmental protection function of the new building materials: the use of laminated glass can not only isolated can penetrate ordinary glass 1000 Hz - 2000 Hz with noise, and it can block more than 99% ultraviolet radiation and absorption infrared spectroscopy in the heat. As with the new building materials properties of laminated glass is bound in safety glass use play a huge role in. More about: Flat/curved laminated glass price
