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?

The glass steel base material is a physical and chemical change of reinforcing material coated and firmly bonded component materials. Glass steel base material made of synthetic resin and auxiliary materials, wherein the synthetic resin is the main component. Matrix materials in FRP is the load transfer between fibers, and the load balancing. The properties of the matrix materials, such as corrosion resistance, heat resistance, directly affect the performance of FRP. Glass steel process determines the forming process of its choice.

Q:What is the raw material of glass products?

Ordinary glass is the raw material of soda (sodium carbonate), limestone (calcium carbonate) and silica by high temperature reaction, with sodium silicate, calcium silicate and silica products, according to the needs of different substances will add color.For example, adding chromium oxide (Cr2O3) glass, is green; adding manganese dioxide (MnO2), purple glass; adding cobalt oxide (Co2O3) glass, blue glass, copper, copper oxide is high if the glass appeared blue and green; in order to lower the price of cuprous oxide (Cu2O) when there is red glass.Now, people use the oxide of rare earth elements as coloring agents to make all kinds of high-grade color glass. Colored glass doped with rare earth elements has a bright, bright color and even changes colors in different light. For example, in the glass of neodymium oxide has this characteristic, it shows purple red in the sunlight, in the fluorescence of purple blue, very beautiful. There is a kind of glass that changes with the intensity of light. People use it as the lens of glasses and the window glass of the house. With this kind of glass as a window, the room can maintain a certain brightness, and no longer need to use curtains to shade, so some people call it "automatic curtain"". It can prevent the UV rays of the sun through the library and Museum Library, installed on the glass, can protect the books and cultural relics from UV damage, in addition to the rare earths, directly adding tungsten and platinum in the glass, can also be made of glass.

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

Q:As the raw material for glass wool is what

Collectively, the fibrous silicate glass wool can be split into thin and flexible fiber and available.Glass wool has been used for thousands of years of history.

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:What is the raw material of glass fiber reinforced plastics and what is the matching ratio?

Hand paste raw material: surface felt, short cut felt, square cloth.Winding: continuous fiber, surface felt, stitched felt, mesh fabricMolding, BMCRatio: surface felt: resin =1:9

Q:What is inorganic glass?Want to be a fish tank, where can I find inorganic glass?

Inorganic glass is quartz (SiO2) glass. Its toughness and strength are better than that of organic glass, but inorganic glass has good corrosion resistance and high temperature resistance. It is superior to plexiglass

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

There is almost no plastic for sun lenses, so it is better to use resin materials.Sunglasses are mainly made of two kinds of glass material and resin material.

Q:What is acrylic material?

Acrylic properties;1. excellent transparencyColorless transparent plexiglass plate, light transmittance of more than 92%2. excellent weather resistanceAdaptability to the natural environment is very strong, even for a long time in sunlight, wind and rain will not change its performance, anti-aging properties, and can also feel comfortable in the outdoor use.3. good processabilityThe utility model is suitable for mechanical processing and easy thermal forming, and the acrylic plate can be dyed, and the surface can be painted, silk screen or vacuum coating.4. excellent comprehensive performanceAcrylic plate has many varieties, rich colors and excellent comprehensive properties. It provides diversified choices for the designers. The acrylic board can be dyed, and the surface can be painted, silk screen or vacuum coating.
