Q:May I ask what specific aspects of German foam glass and foam glass made in China are?
The domestic production line (excluding the line), you can imagine the bread, a fixed container, the raw material grinding and mixing placed in the container, into the furnace after foaming, molding and demoulding, manual cutting required size (note here will produce a large number of loss; 100%) not using waste glass.
Q:What kind of film is toughened glass film?
How to identify good protective film for toughened glass:1., bad exhaust surface residual bubble phenomenon;2., toughened glass can not stick around the corner, bubble phenomenon;3., toughened glass and mobile phone adhesion, easy to fall off phenomenon;4., toughened glass is too thick, affecting transmittance, and thickening of mobile phone thickness;5., toughened glass sticking glue is too thick, affect the mobile phone display transmittance;6. toughened glass is pasted on the mobile phone, and the surface of the mobile phone has a watermark phenomenon.7., toughened glass film is also straight edge and arc edge, arc edge relative to the more rounded, not easy to hurt hand
Q:Comparison of plexiglass steel bridge and inorganic glass steel bridge
4, can release harmful gases, human health and environmental protection have a certain impact. 5, high cost, but also a larger fluctuation of raw material prices. 6, after the waste is not easy to handle. Two, inorganic glass fiber reinforced plastics (referred to as Magnesium Oxide) advantages: 1, high temperature. (under normal circumstances, Fahrenheit temperature of 400 degrees Celsius, to maintain the product is not deformed), 2, anti-aging, 20 years without deformation of the product. 3. Purify the air and absorb carbon dioxide from the air. 4, high strength. 5, waterproof performance is good. 6, light weight, only in plexiglass.
Q:Glass raw materials processing equipment, glass raw materials crushing equipment prices generally sell how much?
The above two processes generally has the following disadvantages: 1, unit 2, a large scale of investment products; metal consumption per unit of product 3, amazing; by-products (<0.1mm) high proportion; 4, wet production requires a large amount of water and cold in winter can not produce.
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:What are the Department of mobile phone lens?
Well, yes, coating is coated, but not what you said, the film, this forgot to say, but generally speaking, is this, in fact, is not very complicated process, as long as there is equipment, it is easy to handle!
Q:How is glass made, raw material proportioning?
The glass is the main component in the manufacturing process of quartz sand, quartz sand is combined with other chemical materials at high temperature (1300 degrees Celsius) crystallized after firing the cooling of the body, with a hard, abrasion resistance, corrosion resistance and high transmittance characteristics, its wide application has a long history.
Q:Aluminum alloy window glass tape, how fast loading?
The inside mounting method is opposite to the outside installation method, that is, the operator stands on the indoor floor or indoor high stool to install the glass of the aluminum alloy door and window. In the first window in the fixed slot lateral seal, safety glass, positioning, and then fixed to the inside of the notch is injected in the cavity joint sealant fixed, which is dry and wet two kinds of material mixed use practices.
Q:What are the aluminum films used in glass processing enterprises?
Production lead materials are debited to production costs, manufacturing expenses, sales expenses, and management overhead"Subjects such as "raw materials" are credited.
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.
Our company is a professional glass enterprise that supplies ultra clear glass and all kinds of tinted glass. We also supply glass deep processing. All of our products comply with international quality standards and are greatly appreciated in a variety of markets around the world. We always believe in the business idea of "Your Success, Our Glory". Our aim is to help customers realize their goals. We are making great efforts to achieve this win-win situation.
