Q:What are the construction principles and raw materials of tempered glass?

Tempered glass, also called toughened glass, is a kind of prestressed glass. It uses physical or chemical methods to form a compressive stress layer on the surface of glass. The glass itself has a higher compressive strength and will not cause damage. When the glass is subjected to external force, the pressure layer may be part of the tensile stress offset, avoid broken glass, although tempered glass is in large internal stress state, but the glass no internal defects, without causing damage, so as to achieve the purpose of improving the strength of glass. It is well known that microcracks on the surface of materials are the main causes of material rupture. Because the microcrack will expand gradually under the action of tension, and finally crack along the crack. And because of the large compressive stress on the surface of the glass, the microcracks on the glass surface become more fine and even heal under the action of extrusion".

Q:How can the vacuum tubes of solar water heaters be chromatic aberration? Is purple good or sky blue good?

Features: three, the absorption ratio of executives increased by 12%, the emission ratio decreased by 30% - 40%, super absorption, less heat loss, warming faster. Efficient tube, super absorption, high thermal efficiency, fast heating, in the same light condition, tube can be more than ordinary high temperature hot water; cold tube, due to launch Bibi aluminum ion copper ion is 0.2 lower, so the heat loss is small, can still work normally in the alpine environment, 30 degrees as often out of hot water; high temperature tubes, stainless steel for ion film high temperature resistant, anti air drying coating under the condition of 400 DEG C, aging, decay and discoloration.

Q:Why is the process of glass toughened always broken?

This is because of containing nickel sulfide crystal glass raw material, manufacturing technology in the world is any existing can not be completely avoided, only reduce the exploding probability through control of the purity of raw materials and processing technology to a.

Q:The younger brother wants to know how the octagonal bead is produced Do you use one side of the machine to grind it? What kind of material is usually used in China? Is the price fixed according to the material used?

B grade crystal beads: flat emery discs are cut one by one, and polished by batch machines with a polishing machine!

Q:What is resin glass fiber reinforced plastic?

Raw materials: glass fiber / or its products + resin + (filler) + other additives;Process: hand / pull / winding / molding / injection molding etc..Resin is only a raw material for the production of glass fiber reinforced plastic! That's not what you call it.

Q:What's the price of 0.85mm thick plexiglass, please?

Domestic cheapest, about 400 or so, but the thickness is not enough, the material is poor

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

Reinforced plastics made from glass fiber or its products are referred to as glass fiber reinforced plastics or glass fiber reinforced plastics.

Q:What are the cutting and cutting of acrylic and aluminum-plastic plates?

The aluminum plastic composite plate is a composite material made of chemically treated coated aluminium plate as surface material, polyethylene plastic as core material, and manufactured on special aluminum plate production equipment. The unique properties of aluminum-plastic composite board itself has decided, its wide application: it can be used for building exterior wall, curtain wall, old building renovation, interior walls and ceiling decoration, advertising signs, display rack, dust purification engineering. The utility model belongs to a new type of building decoration material.

Q:The difference between crystal glass and glass

To strike lightly or with fingers. Crystal glass can produce metal crisp sound, and waves a beautiful lingering in the air. We will see at the reception banquet, high-end glasses scenes in the movie, a kind of glass between the collision sound is. And high school, low grade crystal glass sound is also different. Like some low-end crystal glass or ordinary glass voice is relatively boring.

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.
