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?

Ordinary glass float line cooling is a long process, the glass also has compressive stress, but the compressive stress is small, uneven distribution

Q:Aluminum alloy window glass tape, how fast loading?

The above two methods can only use single material, that is dry material or wet material. If the wet material is used, the first side is fixed and the other side is injected with glue and then injected onto the side. Both the inner mounting method and the outboard mounting method are best for both sides using wet material. The watertight and air tightness and the best effect of glial sickness, it is best to use silicone sealant for good. For ordinary simple aluminum alloy doors and windows, the use of single glass, fixed glass, both inside and outside the use of dry materials. For the Aluminum Alloy windows advanced commonly used sandwich or hollow glass, glass raw materials used by the heat absorbing glass processing or colored glass, glass were used for fixing the wet material or mixed material.

Q:What are the paper made of? What is the glass made of? What is the plastic made of?

The common (sodium) glass consists of a mixture of sodium silicate and calcium silicate with a small amount of silica and alumina. Usually made from a mixture of sand, sodium carbonate and calcium carbonate, and can be melted by a mixture of sodium sulphate and carbon instead of sodium carbonate.

Q:There are several ways of heating the industrial drying tunnel furnace and are different from each other?

Product features:1., small size, high power: the electric heater mainly uses the cluster type tubular heating element, the maximum power of each cluster type tubular electric heating element is 5000KW.2. thermal response fast, high temperature control accuracy, high comprehensive thermal efficiency.3., wide range of applications, adaptability: the cycle heater can be applied to explosion-proof or ordinary occasions, its explosion rating up to B and C class, its pressure up to 20Mpa. The cylinder can be installed vertically or horizontally according to user needs.4., high heating temperature: the heater design maximum operating temperature of up to 850 degrees, which is generally can not get the heat exchanger.5. fully automatic control: through the heater circuit design, it is easy to realize the export temperature, pressure, flow and other parameters automatic control, and can be networked with the computer, to achieve man-machine dialogue.

Q:What materials do you need to make glass?

The chemical composition of ordinary glass is Na2O, CaO, 6SiO2, the main component is silica, is a kind of amorphous structure with irregular structure. Widely used in buildings for wind and light transmission; of mixtures.

Q:The difference between glass wool, rock wool, mineral wool

Glass wool belongs to a kind of glass fiber, it is a kind of man-made inorganic fiber. Glass wool is the molten glass fibrosis, the formation of cotton like material, chemical composition of glass, is a kind of inorganic fibers. With good forming, small volume density, thermal conductivity, both thermal insulation, sound-absorbing performance, corrosion resistance, chemical stability.

Q:Glass raw materials, in addition to quartz sand, what else can be the main raw materials?

Glass raw materials are: soda ash, limestone, quartz, the ratio is: 1:1:6

Q:Does fiberglass contain formaldehyde? I'm a hair salon. Buy a glass fiber reinforced plastic shampoo bed, there is always a pungent smell of the body, there is no harm to it, including formaldehyde free

Because of the different kinds of resins used, they are called polyester glass fiber reinforced plastics, epoxy glass fiber reinforced plastics and phenolic resin glass fiber reinforced plastics. The main raw materials of glass fiber reinforced plastics are resin, curing agent and glass fiber. Glass fiber is not toxic, but contact the skin will be itching. And resin and curing agent have certain harm to human body, especially curing agent, if it is the curing agent of aromatic amine, that is relatively harmful to human body.

Q:Is glass steel pipe used for re examination?

The basic construction phase: reinforced approach sampling, sample (drawing on the provisions of the various specifications of reinforced earth excavation (), earthwork excavation scheme, technical tests, foundation trench inspection records, batch inspection, inspection, hidden) cushion (hidden, concrete construction inspection group, line records, line technology review), base (reinforced raw materials, test report review, reinforcement, formwork and concrete construction scheme, technical disclosure, concealment, reinforced bar, inspection lot, line records, technical review, concrete concealed, concrete construction inspection group, and with the standard curing conditions and stripping test block), basic brick (program, technical disclosure, in advance. Mix ratio of mortar, concealment, inspection batch, mortar block), the template removal (removal of specimen report report, concealment, inspection batch), backfill (scheme, technical clarification Concealment, inspection, batch, earthwork density test).

Q:The benefits of natural thin wood planks

Sheet material means a flat rectangular building material plate with a width of more than 2 times its thickness, usually made of flat rectangular building material, used as a wall, ceiling, or floor member. Also refers to the forging, rolling or casting of the metal plate, divided into thin plate, medium plate, thick plate, thick plate, usually made of standard size flat rectangular building material board.
