Q:Tempered glass and ordinary glass raw materials the same, but the manufacturing method is different, why first heating in rapid cooling, the difference is so great?

Ordinary glass float line cooling is a long process, the glass also has compressive stress, but the compressive stress is small, uneven distribution

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 kind of material is the glass made of? Is the price relative to the quality?

The main raw material of silicon dioxide, the price is related to the quality

Q:Tile selection, paving process

Q:What's the price of 0.85mm thick plexiglass, please?

Domestic cheapest, about 400 or so, but the thickness is not enough, the material is poor

Q:Is glass fiber reinforced plastic board fireproof partition board?

A type of fireproof partition board. Glass fiber reinforced plastic sheet is flame retardant and does not support combustion performance. It can be classified into grade a fireproof board in fire prevention and fire fighting.

Q:What is the difference between acrylic board, lotus board, organic board and PVC board?

PVC board is a kind of vacuum plastic film. It is used in the surface packing of various panels, so it is also called decorative film and adhesive film. It is applied to many fields such as building materials, packaging, medicine and so on. Among them, the building materials industry accounted for the largest proportion, 60%, followed by the packaging industry, as well as other small range of applications. According to the degree of soft and hard can be divided into soft PVC and hard PVC. According to the production process can be divided into PVC crust foam board and PVC free foaming board.

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:Is glass steel pipe used for re examination?
