Q:Toughened glass and ordinary glass, process and raw materials what is the difference, a little more detailed, thank you

Toughened glass is the re processed product of ordinary glass.The main components in the glass is silicon dioxide, calcium oxide and sodium oxide, so called silicate glass. There are two ways to make glass toughened. They are physical tempered (air cooled steel) and chemical steel.Tempered glass adopts a chemical tempering method. The principle is the sodium ion with the "head" the larger potassium ions replace the glass surface "head" is small, so that the glass surface is a state, which is the formation of compressive stress, so that the glass has very high impact resistance (increased by about 5 times).

Q:Are there any materials that need to be tested in curtain work?

Hidden works, batch inspection of raw materials, report, commencement report, division of engineering, engineering, testing report report is mainly hanging plate before the covert acceptance, including steel keel, anticorrosion material inspection, etc..

Q:Polypropylene short fiber and glass fiber if different

Polypropylene fiber is resistant to acid and alkali, and glass fiber has poor alkali resistance.

Q:Renovation of the house to buy bricks when how to see the quality of good or bad? What kind of good?

According to the degree of finish is divided into yaguangyoumianzhuan and light glazed tiles. At present, the ground material with more matte glazed tiles.The tiles (or tiles) is the use of earth embryo (or earth embryo to add some ore powder) after high temperature and high pressure one-time firing, using the surface and bottom of embryo material basically identical (except for the special process such as tiles, tiles in the new fill glaze series). Vitreous tile belongs to all ceramic product. Its abrasion resistance and flexural strength are very high, the water absorption rate (tile water absorption rate is less than 1 per thousand). Before the tiles mainly used for flooring, tiles, as a wall material is mainly used for high-grade Gaestgiveriet Hotel, office space, but now, with the living standard and the improvement of consumption level, the home use tiles for the kitchen wall materials are more and more family.

Q:Is acrylic organic glass?Which is more expensive, acrylic or plexiglass?

Organic glass is an important heat, a development of earlier plastic, with transparency, chemical stability and good weathering resistance, easy to dye, easy processing, beautiful appearance, is widely used in the construction industry. The plexiglass product usually can be divided into casting plate, plastic extrusion board and the mold.Acrylic is much more expensive than plexiglass

Q:Is toughened glass dish loaded with food harmful to human body?

The main chemical composition of glass products is silicon dioxide, sodium oxide, calcium oxide and other inorganic compounds, the precipitates of tableware national limit has strict rules, regular production of glass tableware, kitchenware is not harmful to humans, so consumers do not have to worry about the basic glass tableware utensils will cause harm to food safety. Daily exposure of glass tableware from the material can be divided into sodium, calcium, glass, that is, ordinary glass, borosilicate glass, lead crystal glass, glass ceramics.

Q:What are the raw materials for low dielectric glass fiber?

Glass fiber according to shape and length, can be divided into continuous fiber length, fiber and glass wool; according to the glass component, can be divided into non alkali, chemical resistance, high alkali, alkali, high strength, high elastic modulus and alkali resistant glass fiber etc..The main raw material for the production of glass fiber are: quartz sand, limestone, dolomite, alumina and pyrophyllite, boric acid, sodium carbonate, mirabilite and fluorite etc.. The production methods can be roughly divided into two categories: one is the molten glass directly into the fiber; one is the molten glass into the first 20mm diameter glass ball or rod, in a variety of ways made by heating a diameter of 3 ~ 80 m very fine fiber. An infinitely long fiber drawn from a platinum alloy plate by mechanical wire drawing is called continuous glass fiber, commonly known as long fiber. A discontinuous fiber made from a roller or air flow, called a fixed length glass fiber, commonly referred to as staple. Fine, short, flocculent fibers made from centrifugal force or high velocity air flow, called glass wool. Glass fibers are processed into various shapes, such as yarn, roving, chopped strand, cloth, band, felt, plate, tube, etc..

Q:What material is used in the protective film in the middle of glass?

At present, toughened glass membrane of glass raw materials generally have these brands. High end: Corelle & Schott. In the end: asahi. In the low-end: banxiaozi & luoyang.Just look different brands? The difference between JEANSWEST and Reaves? No, focusing on different materials.The same glass, medium and high-end glass called "aluminum silicon glass" in the low-end known as [sodium calcium glass]

Q:What is the raw material of glass made of?

Our daily contact with most of the "flat glass is" thick to thin for doors and windows, clocks and the use of medical tests, the manufacturing method is that the furnace in the glass slurry level or traction method (also called float) and vertical traction method. After the dissolution of soluble traction after furnace also has the cooling system, cooling after the completion into a "flat glass, flat glass thickness mainly depends on the speed of traction, traction faster, can be manufactured and thinner. Although the ordinary flat glass from the front appears bright transparent, but from the side near the edge is slightly blue, because the amount of glass color depends on the main raw material in the manufacture of glass - quartz sand and iron content of purity. Generally, the thin glass used in the watch industry is superior in quality but expensive in value. The main difference is that the raw material used in the quartz sand is superior and the iron content is very low (usually under 3/10000)

Q:What is the raw material of glass?

How is glass produced? Glass production process includes batching, melting, forming, annealing and other processes. The following are described below:1. ingredients, according to the design of the material sheet, weighing all kinds of raw materials, mixing in a mixing machine evenly. The main raw materials of glass are: quartz sand, limestone, feldspar, soda ash, boric acid and so on.2., melting, the raw materials will be prepared by high temperature heating, forming a homogeneous bubble free liquid glass. This is a complex process of physics and chemistry. The melting of glass is carried out in a furnace. There are two main types of Furnaces: one is a crucible kiln, the other is glass in the crucible, and the other is heated outside the crucible. The small crucible kiln has only one crucible, and the larger one can be more than 20 crucibles. The crucible kiln is made by gap type, and now only optical glass and color glass are produced by crucible kiln. The other is the tank furnace. The frit is molten in the bath, and the flame is heated on the upper part of the glass. The glass melting temperature mostly in the 1300~1600 C Eve joy. Most of them are heated by flame and a few are heated by electric current. They are called electric furnaces. Now, the pool kiln is continuous production, small pool kiln can be a few meters, big can be more than 400 meters, 2.
