Q:Is it a vacuum cup with fluorine coating that affects the health?

Does not affect the health, only in the temperature of more than 200 degrees will be long life of harmful substances.

Q:What are the chemicals in glass?

Common raw materials are quartz sand, feldspar, calcite, calcium carbonate, three, two aluminum oxide, sodium carbonate, borax and so on.

Q:Tempered and reinforced glass

National construction technical specification for application of glass JGJ113-2003 provisions of the landing door glass must use safe glass, is from the protection of person to consider.

Q:What are the anticorrosive materials for glass fiber reinforced plastic?

FRP is made of glass fiber and epoxy resin, is the best anti-corrosion material, regardless of category, can be anti-corrosion.FRP corrosion protection is generally stipulated in the GB50212-2002 building corrosion control project construction and acceptance specifications and CD130A19-85 hand paste FRP design technical specifications.

Q:What kind of mineral is glass made of?

Colored glass is made by adding some metal oxides in the manufacture of ordinary glass. Cu2O - red; CuO - blue-green; CdO - pale yellow; CO2O3 - blue; Ni2O3 - dark green; MnO2 - purple; colloidal Au - red; colloidal Ag - yellow)

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

Appearance: A, nozzle, where the film is more than 800 degrees Celsius, sealing at high temperatures, part of the fall is inevitable. High temperature tube because of high temperature resistance, only about 1 cm long without film, while other tubes because of high temperature resistance, film shedding, length of about 2.5 cm. B, inner tube color: with naked eye observation, high temperature and high temperature pipe inner tube color is dark red (because the film bottom is copper), and the high efficiency tube and ordinary pipe is white (because the film bottom is aluminum). The third kind: Zijin tube, which is plated with copper, absorbs heat and is better than three executives. The color is purple, so it is called purple tube

Q:Why is the process of glass toughened always broken?

It blew the concept of rate, the national standard of our country only glass project on the wall, I do not know whether the other foreign industry to use the toughened glass also has detailed provisions.

Q:What is the glass DV board made of?.

Glass is formed by melting sand with other chemicals (the main ingredients are: soda ash, limestone, quartz). A continuous network structure is formed during melting, and the silicate like non-metallic material is gradually increased and hardened in the process of cooling.

Q:What are the main materials for making glass?

The melting point of silicon dioxide is very high, in order to achieve this Rongdian is very limited. The ancients had to add some other substances when it becomes low melting temperature. When silica melts down also very obtrusive in the process of heating without gradually filtering transition soft, into some other the material of the glass can be in different temperature range all the splendor, powerful shaping operation and effective setting. This substance is a flux.The flux is generally containing sodium oxide, potassium oxide, lead oxide, calcium oxide, barium oxide and other materials, such as limestone, feldspar, sodium carbonate, boric acid, lead compounds, barium compounds. (sodium oxide can reduce the viscosity of glass forming, the glass is easy to melt, plays a good role in flux; barium oxide in glass the formation plays a basic role with sodium oxide; tin oxide can increase the glass chemical stability and mechanical strength; lead oxide can increase density, improve hunting, with special luster; lead can make a glass of light refraction and scattering rate of small glass makes more lustrous and stable.

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

Float glass surface flat, good brightness, no tumor and bubble (less).The surface of the lattice is not very smooth, and the ripples can be seen from the side. Uneven thickness
