Q:Is the price of glass raw material the biggest proportion of quartz?

The price of raw materials is the largest proportion of quartz sand.

Q:What is glass made of?

Melting, the raw materials will be prepared by high temperature heating, forming a homogeneous bubble free liquid glass. This is a complex process of physics and chemistry. The melting of glass is carried out in a furnace. There are two main types of Furnaces: one is a crucible kiln, the other is glass in the crucible, and the other is heated outside the crucible. The small crucible kiln has only one crucible, and the larger one can be more than 20 crucibles. The crucible kiln is made by gap type, and now only optical glass and color glass are produced by crucible kiln. The other is the tank furnace. The frit is molten in the bath, and the flame is heated on the upper part of the glass. The glass melting temperature mostly in the 1300~1600 C Eve joy. Most of them are heated by flame and a few are heated by electric current. They are called electric furnaces. Now, the pool kiln is continuous production, small pool kiln can be a few meters, big can be more than 400 meters

Q:Toughened glass and ordinary glass, process and raw materials what is the difference, a little more detailed, thank you

Same material. Tempered glass is ordinary flat glass or float glass in a specific process conditions, by quenching or air-cooled quenching processing processing, Baidu has "toughened glass" entry.

Q:Is acrylic organic glass?Which is more expensive, acrylic or plexiglass?

Acrylic has high transparency, light transmission rate of 92%, a "plastic crystal" reputation. And has excellent weather resistance, especially in outdoor applications, among other plastic crown, and with good surface hardness and luster, processing and plasticity, can be made into various required shapes and other types of sheet products. There are rich colors (including the translucent shade guide), the other is characterized by thick still maintain a high level of transparency.

Q:What are the raw materials for producing edible glass bottles (such as pickles bottles, fermented beancurd bottles, etc.), and glass is the kind of glass material?

In the production of glass products, raw materials are divided into general white material, high white material, super white material, and white material, the quality is getting better, he directly affects the glass transparency and crispness, better raw materials produced better quality glass products.

Q:Can ordinary white glass (Bai Jiuping) replace quartz glass?

Quartz glass has a series of excellent physical and chemical properties, such as: 1, high temperature resistance. The softening point temperature of quartz glass is about 1730 DEG C, which can be used for a long time at 1100 DEG C, and the maximum temperature can reach 1450 DEG C for a short time. 2, corrosion resistance. Except hydrofluoric acid, quartz glass and other acids almost no chemical reaction, the acid resistance is 30 times 150 times of ceramic, stainless steel, especially the chemical stability at high temperatures, any other engineering materials are incomparable. 3. Good thermal stability. The quartz glass thermal expansion coefficient is extremely small, can withstand the temperature changes, the quartz glass is heated to 1100 degrees Celsius, the water will not burst into the room. 4, good light transmission performance. The quartz glass has better transmittance in the whole spectral range from ultraviolet to infrared, and the transmittance of visible light is above 93%. Especially in the ultraviolet spectrum region, the maximum transmittance is above 80%. 5 、 good electrical insulation performance. The resistance of quartz glass is equal to ten thousand times of that of ordinary glass. It is an excellent insulating material. It has good electrical properties even at high temperature.

Q:What kinds of ingredients are the glass?

Flint glass is a high density and high refractive index glass. It can be produced by lead instead of calcium in sodium glass in molten glass. It is suitable for making optical glass and carved glass products. The coefficient of thermal expansion of hard glass is very high

Q:Long plastic soft glass is a food grade raw materials?

No, this is the PVC material processing process, there will be plasticizers, etc., although non-toxic, harmless, but the food grade standards or worse.

Q:What materials do we need to make glass septic tanks?

9., the product covers only 60 ~ 80% of the brick and concrete septic tank, which saves land and improves the flexibility of site selection.10., the comprehensive cost is low, and the overall cost is more economical compared with the brick and concrete septic tank.

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.
