Q:The main chemical constituents of ordinary glass

In the process of making glass, if you add some metal oxides, can also be made of colored glass. For example, adding Co2O3 (cobalt oxide) after the glass is blue, after joining the Cu2O glass is red. We see the ordinary glass, generally pale green, this is because the raw material is mixed with two valent iron for the sake of.There are many kinds of glass. Besides the ordinary glass introduced above, there are some other kinds of glass, such as quartz glass, optical glass, and so on

Q:What are the construction principles and raw materials of tempered glass?

Tempered glass is the two processing product of flat glass. The processing of toughened glass can be divided into physical toughening method and chemical toughening method. Physical toughened glass is also called tempered tempered glass. It is the ordinary flat glass in heating furnace heated to the softening temperature close to the glass (600 DEG C), the internal stress of the self deformation is eliminated, and then removed from the glass furnace, with long nozzle high pressure cold air blowing glass on both sides, the rapid and uniform cooling to room temperature, well tempered glass can be made. This kind of glass in the internal and external tension compression stress state, once the local damage occurs, the stress release, the glass is broken into small pieces, these small pieces no sharp edges, not easy to hurt. In the production of tempered glass, the most influential factor on the quality of the product is how to make the glass form a larger and uniform internal stress. But the greatest impact on yield is how to prevent cracking and deformation.

Q:List and characteristics of chimney glass flake cement

Glass scales prevent the erosion of base material by water vapor and chemical solvents. The degree of chemical resistance of the substrate or coating varies with the chosen glass material, and the glass scale made of C- glass has excellent chemical durability.

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

Composition of common glass chemical oxides (Na2O, CaO, 6SiO2)Glass is usually divided into oxide, glass, and non oxide glass by major components. Non oxide glass varieties and a small number, mainly sulfur glass and halide glass. Chalcogenide glass anion for sulfur, selenium and tellurium, can stop short wave light by yellow, red, and near infrared light, which has low resistance, switching and memory characteristics. Having low refractive index, low dispersion, and often used as optical glass.

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

Phenolic insulation board is based on phenolic resin and flame retardant, anti smoke agent, a variety of material, curing agent, foaming agent and other additives, closed cell rigid foam made by scientific formula. The most prominent advantage is fireproof and insulation.

Q:Which brand of thermos cup is safe, double glass is not really glass, there is no other add, affect health?

Double glass also called light industrial glass, raw materials for high boron silicon has a high heat resistance, the main production of glass teapot, coffee cup, cup, cup of hot water, there are many domestic manufacturers.

Q:What are the raw materials of glass fiber reinforced plastic?

It is a kind of composite material made of glass fiber and its products (glass cloth, band, felt, yarn, etc.) as reinforcing material and synthetic resin as base material.

Q:How do you pack something into (Qian Jin) plexiglass?

I have been in touch with gel products for a while, and I feel that if the discharge circuit is too soft, it will be easy to damage the circuit board. As far as plexiglass is concerned, I have to ask my fellow inorganic students how they did it.

Q:Does the material of sunglasses choose good glass or plastic?

Glass materials of high hardness, not prone to scratches, shock resistance is poor, after the impact of easily broken, and the weight is relatively heavy.

Q:Why is toughened glass broken?

There are a variety of predisposing factors. Tempered glass explodeFor example, A. before the installation of glass is accidentally damaged, like chipping, knocked the feet, because the glass is tempered around the weak area, its strength even weaker than the non tempered glass, but this part of the damage are not likely to cause the glass immediately burst, but changed the internal stress of glass. When the upper wall is used, the internal stress changes gradually, which breaks the glass.B. such as differences in temperature after installation. As you say, temperature, weather, and so on, will make the internal pressure of the glass partial uneven, thus causing burst.Is there a correct size for the C. installation?. If the installation is too tight, the specifications are not appropriate, it will cause stress changes inside the glass, causing a burst.D. the rest is external force, including impact, extrusion and so on. It's not just human impact, or other things, or even wind in nature. If the glass does not fall on the ground, there will be the point of impact (if it is obvious, there will be explosive, Hu Dieban) these can be invoked, but if in the proceedings can only be said to be a possibility, because you have no evidence to prove that. In the domestic situation, the glass manufacturers generally compensate for the glass trouble.
