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:How is glass made? What are the main ingredients?

Preparation of batch. According to the product, the composition of the mixture is slightly different. For example, ordinary float glass batch (calculated in accordance with 1 weight boxes of 50 kilograms), need to consume 33.55 kg of quartz sand, limestone, dolomite, 2.96 kg 8.57 kg 11.39 kg of soda, Glauber's salt 0.55 kg, 3.45 kg, 0.03 kg of feldspar powder etc..

Q:The preparation process of glass and the basic material and the function of raw materials

Feldspar provides Al2O3 and enhances chemical stability in glass;Glauber's salt helps the high temperature glass to remove bubbles produced by carbonates in other materials

Q:How to identify and select high quality insulating glass?

At present, there are three kinds of insulating glass in China: (1) groove aluminum type single channel sealing; (two) groove aluminum double channel sealing; (three) compound sealant strip type insulating glass. Groove type aluminum single channel seal, because of its poor sealing, easy to enter moisture, resulting in condensation of glass, frosting, short service life, so the kind of insulating glass gradually eliminated.

Q:Cement / glass raw materials, equipment, principle, composition, characteristics, uses and types

A mixture of feldspar, potassium aluminum silicate (K2O, Al2O3, 6SiO2) and albite (Na2O, Al2O3, 6SiO2) used in dental ceramics. Natural feldspar is not pure, and the proportions of K2O and Na2O vary. At about 1250 to 1500 degrees C (2280~2370 degrees F), feldspar melts into glass with a free crystalline silicon phase. In the feldspar Na2O can reduce the melting temperature, and potassium can increase the glass melt viscosity, reduce the plastic flow during sintering heat (pyroplastic flow).

Q:A fireproof material is? Except glass wool, rock wool? Please tell me what is the raw material of these materials is?

Application of phenolic insulation board: the polystyrene foam and polyurethane foam are flammable, no high temperature in some industries in developed countries are restricting the use of the fire department, the fire place of strict requirements, government departments have been expressly provided only with phenolic insulation board. Therefore, phenolic foam is more suitable for high performance materials demanding conditions of use, has good prospects for development. Such as steel structure workshop, large industrial plants, activity room, cold storage, clean workshop, building storey, temporary housing, gymnasium, supermarket and other needs of fire insulation requirements of buildings.

Q:Aluminum alloy window material is good, how to assemble?

Glass: used for aluminum alloy doors and windows, ordinary flat glass, it is best to float process produced by flat glass. There are toughened glass, pointed glass, heat reflective glass, etc..Auxiliary material: filling material, glass cushion block, sealing material.Filling material: it is used as the backing material for filling seam. It belongs to R polymer foam, and its shape is generally round, semicircle, oval and triangle. Specifications are lOmm, 30mm and 50mm three kinds of polyethylene foam. The elongation is 50% and tensile strength is between 0.359 and 0.517MPa.

Q:Does fiberglass contain formaldehyde? I'm a hair salon. Buy a glass fiber reinforced plastic shampoo bed, there is always a pungent smell of the body, there is no harm to it, including formaldehyde free

Because of the different kinds of resins used, they are called polyester glass fiber reinforced plastics, epoxy glass fiber reinforced plastics and phenolic resin glass fiber reinforced plastics. The main raw materials of glass fiber reinforced plastics are resin, curing agent and glass fiber. Glass fiber is not toxic, but contact the skin will be itching. And resin and curing agent have certain harm to human body, especially curing agent, if it is the curing agent of aromatic amine, that is relatively harmful to human body.

Q:What chemicals can be made from glass, paper, detergents, etc?

Glass: quartz, sodium carbonate, calcium carbonate paper: bark is enough.. cellulose + bleaching agent, such as activated carbon and other detergents, soap bar, sodium stearate

Q:How do I see whether the raw material of tempered glass is made of float glass or standard glass?!

In the sun or under the light, look at the projection, float shadow is very weak, light transmission of good, lattice black lines, one by one
