FAQ

Can the toughened glass be cracked by the sun?

thermal stabilityTempered glass has good thermal stability, can withstand the temperature difference is 3 times of ordinary glass, can withstand the temperature difference of 300 degrees celsius.

What are the construction principles and raw materials of tempered glass?

Tempered glass, also called toughened glass, is a kind of prestressed glass. It uses physical or chemical methods to form a compressive stress layer on the surface of glass. The glass itself has a higher compressive strength and will not cause damage. When the glass is subjected to external force, the pressure layer may be part of the tensile stress offset, avoid broken glass, although tempered glass is in large internal stress state, but the glass no internal defects, without causing damage, so as to achieve the purpose of improving the strength of glass. It is well known that microcracks on the surface of materials are the main causes of material rupture. Because the microcrack will expand gradually under the action of tension, and finally crack along the crack. And because of the large compressive stress on the surface of the glass, the microcracks on the glass surface become more fine and even heal under the action of extrusion".

How is glass made? What is its raw material?

Glass is classified into flat glass and deep-processing glass. Flat glass is mainly divided into three kinds: that is, lead glass, two kinds of flat glass (slot / no groove), flat glass and float glass. The float glass is becoming the mainstream of glass manufacture because of its uniform thickness, flat top and bottom surface, high labor productivity and favorable management. And special glass is a large variety

What's the name of the transparent plastic board in the market?

Organic glass acrylic and special processing, organic glass products, light boxes with acrylic production has good transparence, pure color, rich colors, beautiful smooth, both day and night of two kinds of effect, long service life, does not affect the use of other features, in addition, acrylic and aluminum plate material, advanced screen printing etc. can be the perfect combination, to meet the business needs of acrylic plastic is to improve the store level business, unified enterprise image of the best form of outdoor advertising.

What chemicals added to the PVB resin powder can be diluted into a transparent liquid?

1) PVB resinPVB intermediate membrane is mainly made of PVB resin..PVB resin is a macromolecule compound obtained by the reaction of polyvinyl alcohol and polyvinyl alcohol under the catalysis of strong acidPVB resin is non-toxic, odorless, non corrosive, non flammable, has good light transmittance, insulation, weather resistance, abrasion resistance, water resistance, oil resistance, aging resistance, adhesive and transparent special properties of inorganic and organic glass. Sandwich materials can be used as safety glass, and can be made transparent other materials used.2) plasticizersPlasticizer 3G8 used in PVB intermediate film has good phase solubility with PVB resin, and has good cold resistance, heat resistance and so on3) additivesIn addition to the above two main raw materials, PVB intermediate membrane, in order to adjust the adhesive force, improve the weather resistance and isolate ultraviolet radiation, also added a relay regulator, antioxidant, UV absorbers and other additives

Aluminum alloy window material is good, how to assemble?

Sealing material: according to its different material, can be divided into structural sealant, building sealant (weather glue) and insulating glass two sealant. Structural sealant can be divided into one component and two components, two kinds. One component sealant, acid sealant and neutral sealant and so on. According to the method of fixing and fixing glass, the sealing material is divided into two kinds: dry material and wet material. When in use, the utility model can be used both inside and outside of the dry material, and can also be used for both inside and outside, and can be used in a mixed way. That is to say, when the outer side of the glass is arranged, the inner part of the glass is dry, and the outer part of the wet material or the inner side of the glass is provided with wet material for external use and dry. Dry material is finished product (market), according to its aluminum alloy notch in the form of different and divided into several kinds, soft and hard degrees are also different.

Who has information about power plants chimneys, water glass, acid resistant concrete?

The characteristics of water glass concrete acid: water glass acid resistant concrete with water glass as binder, sodium fluorosilicate as hardening agent, adding acid powder and acid aggregate or other additives according to a certain proportion. Features: the acid and good heat resistance, it can resist all kinds of strong oxidizing acid (such as sulfuric acid, hydrochloric acid, nitric acid) and most corrosive gases (oxygen, sulfur dioxide) erosion at high temperature (1000 DEG C) still has good acid resistance, mechanical strength and high. But this material is not resistant to hydrofluoric acid, more than 300 degrees of hot phosphoric acid and higher fatty acids or oleic acid erosion. Is a commonly used anti-corrosion material, it has a wide range of materials, acid resistance good, low cost advantages. Its disadvantages are no alkali resistance, poor impermeability and water resistance, complex construction, long maintenance period.

Is the production of glass materials as thin as possible? Why?

Glass production is very strict to the granularity of various raw materials, and there is a usable range. Generally, refractory materials are finer, such as sand and feldspar. Some of them are coarse, such as dolomite and limestone. However, the most taboo is "superfine powder""!
