Q: How do you make the glass, please? What is the raw material?: When you look for information, the proportion of raw materials is very important.

Q: What kind of glass is alkali free high borosilicate?: With low density, high chemical durability, and excellent thermal stability, it also has the surface clean, widely used in TFT-LCD LCD glass substrate, excellent flatness characteristics of up to 92% of the visible light transmittance, and excellent alkali precipitation, widely used in optical coating industry, semiconductor industry.

Q: Do solar panels use toughened glass, or are some high light transmitting materials good?: Ultra white glass raw materials imported or made of iron high transmittance (transmission rate of up to 92%), through tempering (heating quenching), so that the strength of the glass increased 3--5 times, broken glass debris particle degree of safety, no harm to human body. The thickness of 2MM, 3MM, 3.2MM 4MM, etc..

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: Is the balance pad the raw material in the motor?: An electric machine is an electromagnetic device that converts or transfers electrical energy according to the law of electromagnetic induction. In a circuit, use the letter M (the old standard uses D). Its main function is to generate driving torque, as a power source for electrical appliances or various machines. The generator is represented by the letter G in the circuit.

Q: A fireproof material is? Except glass wool, rock wool? Please tell me what is the raw material of these materials is?: The performance of phenolic insulation board: 1, excellent fireproof performance: polyurethane and polystyrene and other organic materials, after combustion, will produce smoke and poisonous, easy to cause the deaths, but also increase the difficulty of fire suppression. The phenolic insulation board fire burning, combustion performance up to grade A, the high temperature of 180 DEG C (instantaneous 250 C), 100 mm thick phenolic foam flame resistant capacity of up to 1 hours without penetration. With carbon, no dripping, no curling, no melting phenomenon in the direct effect of flame, the flame surface to form a layer of graphite foam layer, the foam structure effective protection layer in 2, the excellent; insulation properties: low thermal conductivity (

Q: Is the raw material of organic glass harmful to human body?: Organic glass is a popular name. From this name you may not know what kind of material it is, nor can you tell what element it is made of.

Q: Does the material of sunglasses choose good glass or plastic?: Now, the most common use of sunglasses is resin lenses. The resin is a phenolic structure of chemicals, characterized by its light, high temperature resistance, impact resistance, and the ability to effectively block ultraviolet light. It should be said that this is a more excellent sunglasses, lens materials, polarized lenses made of this material will see more clearly.

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: What's the connection between tempered glass and float glass?: Tempered glass will float glass cutting, grinding, drilling, backward tempering furnace heating to glass softening point, rapid and uniform cooling, change the compressive stress of glass, a mechanical properties of good glass products
