- 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?
- When the glass is heated to a suitable temperature, it cools rapidly, causing a sharp contraction of the glass surface and a compressive stress, while the cooling in the middle of the glass is slower and it is too late to shrink, thus forming a tensile stress and making the glass obtain a higher strength. Generally speaking, the higher the cooling intensity, the greater the strength of the glass.
- Q:What kind of raw materials should be used in making FRP?
- Synthetic resin is a kind of synthetic molecules by a large amount of polymer, usually called polymer, also known as synthetic resin in polymer. The performance after heating is different, can be divided into thermosetting resin and thermoplastic resin two categories.Thermosetting resin refers to the heat or curing agent (including initiator) under the action of crosslinks and become insoluble and infusible solid state of a kind of resin, such as epoxy resin, phenolic resin, unsaturated polyester resin, furan resin. This resin can not soften cured after heating. High temperature decomposition and destruction.
- Q:The main chemical constituents of ordinary glass
- Glass is a silicate product that we can see every dayThe window glass is the most common glass, the glass is called ordinary glass. Manufacture of ordinary glass raw material is sodium carbonate, limestone and quartz. The production, the raw materials are crushed and mixed in proper ratio, add heat strengthened glass kiln. Raw material melting happened after the complex physical and chemical changes. Which is the main reaction:Na2CO3SiO2 Na2SiO3CO2 hav'eCaCO3SiO2 CaSiO3CO2 hav'e
- Q:What are the paper made of? What is the glass made of? What is the plastic made of?
- Plastic polymer polymer synthesis {(polymer)}, also known as polymer or giant molecule (macromolecules), is generally known as plastic resin (plastics) or (resin), free to change form style. It is a kind of material which is synthesized by condensation or condensation of monomer material. It is composed of synthetic resin and filler, plasticizer, stabilizer, lubricant, pigment and so on. Its main component is synthetic resin.
- Q:Which glass factory has good glass?
- Fireproof glass, bullet proof glass, gold mirror, Chajing, black mirror, mirror gray, blue mirror... Is the original piece of glass processing, if the original piece of glass (raw material) of the old good to see the unit of processing technology.
- Q:What kind of mineral is glass made of?
- Protective glass (in the ordinary glass manufacturing process to add appropriate auxiliary material, so that it has to prevent light, heat or radiation through the protection of personal safety function. Such as grey - dichromate, iron absorption in the ultraviolet and visible light; blue - Green nickel oxide, FeO absorb infrared and visible light; lead glass - lead absorption of X rays and R rays; dark blue - dichromate, ferrous oxide, iron oxide, UV absorption infrared and most visible light; adding cadmium oxide and boron oxide absorption neutron flux.
- Q:Which brand of thermos cup is safe, double glass is not really glass, there is no other add, affect health?
- Stainless steel material specifications, which 18/8 said that the stainless steel material composition containing 18% chromium, containing 8% nickel, reached the standard materials, in line with the national food standards is the green environmental protection product, rust and corrosion products. Ordinary stainless steel cup body color is pale and dark, if the brine into the concentration of 1% will produce rust after 24 hours, which contains some elements exceed the standard, the direct harm to human health.
- Q:Could you tell me that three yuan ethylene propylene (EPDM) rubber can resist ethylene glycol?
- Three yuan ethylene propylene rubber is ethylene, propylene and non conjugated diene three yuan copolymer, began commercial production in 1963. The consumption of the whole world is 800 thousand tons every year. The most important feature of EPDM is its superior oxidation resistance, ozone resistance and corrosion resistance. Because three yuan ethylene propylene rubber belongs to polyolefin family, it has excellent curing property. Of all rubbers, EPDM has the lowest specific gravity. It absorbs large amounts of fillers and oils and has little effect on properties. Therefore, rubber compounds with low cost can be made.
- Q:Why are most of the chemical instruments made from glass?
- The raw materials of glass equipment, especially now with the more conventional glass GG_17 and 95 of the original material, are high borosilicate glass, the internal structure of the glass with good stability, high physical and chemical properties, because the expansion coefficient is low, so it can better withstand high temperature difference, has chemical stability good performance
- Q:Long plastic soft glass is a food grade raw materials?
- The normal use of the family (including the dining table) is entirely without question
