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

Glass production process is: raw material crushing, screening, weighing, mixing, high temperature (1600 degrees) melting into glass, glass homogenization, cooling molding, cutting, annealing, cooling, inspection, packaging.The main raw materials are: quartz sand or sandstone, feldspar, soda ash, limestone, dolomite, etc., in addition to soda ash are ore raw materials, need to be broken into the appropriate size.

Q:What does GF30 represent in plastic PP GF30?

Polypropylene reinforced by glass fiber, mechanical properties, creep resistance and dimensional stability can be improved,.PP-GF30T has a good low-temperature resistance and high impact strength, PP-GF30 heat resistance

Q:Samsung LCD panel information

This screen is indeed the original Samsung screen, Samsung Electronics, Tianjin Corporation assembly production.TSEC is the sign of Tianjin's samsung. So he wrote the MADE IN CHINA (TSEC) behind him

Q:How can the vacuum tubes of solar water heaters be chromatic aberration? Is purple good or sky blue good?

Fundamental difference: the structure of the film is different, resulting in the principle of absorbing solar rays is not the same. As a multilayer film, the absorption layer is usually 9 layers. It absorbs the solar rays by layer by layer, and absorbs the light gradually. As a result of this gradient structure, the emission ratio increases with the increase of temperature, so that when the working temperature is 300~500 degrees centigrade, the emissivity ratio increases greatly. Moreover, the aluminum ions in the absorption layer are greatly enhanced and shifted at high temperature. In this way, the internal structure of the film is disordered, leading to the aging of the film. At this high temperature for a long time, the film will fall off, thus affecting the heat collection efficiency and life of the vacuum tube.

Q:What's the difference between plexiglass PS boards and toughened glass? What's the difference between them?

Suggest that you use semi tempered glass for bathroom glass, do not use non tempered, and the other two are not high prices, that is, shock resistance, heat resistance is not good, very crispThere is this, now you can choose several materials made of transparent or translucent, (the simplest is to take a rub, ha ha)

Q:What's the difference between three kinds of glass fiber board, epoxy board and FR4 board?

These three are glass fiber boards.Usually the epoxy board on the market is phenolic epoxy, yellow, which is generally not used as a hard circuit board substrate, is the use of electrical insulation.

Q:How is glass made? I heard that sand is used, but what is the concrete principle?

Technological process:1, raw materials broken: the above raw materials broken into powder;2, weighing: according to the list of ingredients, called a certain amount of powder;3, will be called: the mixed powder mixing, stirring into a batch (colored glass and colorant);4, melting: the mixture into the glass furnace, melting at 1700 degrees into glass;5, forming: the glass liquid into a tin bath (float), pull machine (lattice method), rolling machine (rolling method, adding metal wire is wire glass), forming the flat glass;6, annealing: the molding of glass products into the annealing furnace annealing, balance the stress, to prevent self cracking.

Q:Will toughened glass break naturally?

This is because of containing nickel sulfide crystal glass raw material, manufacturing technology in the world is any existing can not be completely avoided, only reduce the exploding probability through control of the purity of raw materials and processing technology to a.

Q:What are the main raw materials for making ceramics, glass and cement?

The main raw materials for producing ceramics are clay (such as Suzhou soil), quartz, feldspar (potassium feldspar and albite)

Q:What are the production processes and raw materials of float glass?

The qualified mixture is then sent to a glass furnace, and in the range of temperature, a uniform glass solution is obtained by melting, clarification, homogenizing and cooling. The glass liquid through the flow passage and launder into the tin bath filled with protective gas of nitrogen and hydrogen, floating on the surface of molten tin, complete glass liquid natural tree, thin, flat show polishing, after cooling, with glass transition roller table hold left into the annealing annealing and tin bath. The annealed glass band can be taken as a product after cutting, checking and packing.
