FAQ

What chemicals added to the PVB resin powder can be diluted into a transparent liquid?
1) PVB resinPVB intermediate membrane is mainly made of PVB resin..PVB resin is a macromolecule compound obtained by the reaction of polyvinyl alcohol and polyvinyl alcohol under the catalysis of strong acidPVB resin is non-toxic, odorless, non corrosive, non flammable, has good light transmittance, insulation, weather resistance, abrasion resistance, water resistance, oil resistance, aging resistance, adhesive and transparent special properties of inorganic and organic glass. Sandwich materials can be used as safety glass, and can be made transparent other materials used.2) plasticizersPlasticizer 3G8 used in PVB intermediate film has good phase solubility with PVB resin, and has good cold resistance, heat resistance and so on3) additivesIn addition to the above two main raw materials, PVB intermediate membrane, in order to adjust the adhesive force, improve the weather resistance and isolate ultraviolet radiation, also added a relay regulator, antioxidant, UV absorbers and other additives
What is glass fiber reinforced nylon?
Compared with pure nylon 3., nylon reinforced mechanical strength, rigidity, heat resistance, creep resistance and fatigue strength greatly increased, elongation, shrinkage, hygroscopicity, wear resistance decreased 4. performance mainly depends on the fiber and resin adhesive strength, content, aspect ratio and orientation. Injection molding and extrusion molding is widely used in aerospace, automotive,. Mechanical, chemical and other fields of manufacturing heat stress structure of plastic parts in 5. PA with 30% glass fiber, PA, mechanical properties, dimensional stability, heat resistance, ageing resistance performance is obviously improved, the fatigue strength is 2.5 times enhancement. 6. reinforced materials used to improve nylon properties of glass fiber reinforced materials, asbestos fiber, carbon fiber, titanium metal, with glass fiber, improve the heat resistance of nylon, dimensional stability, rigidity, mechanical properties (tensile strength and The bending strength, especially mechanical) significantly improves the performance, become excellent performance engineering plastic. Glass fiber reinforced nylon has long fiber and short fiber reinforced nylon two, widely used in gear, bearing, fan blade, impeller, bicycle parts, auto parts, industrial gear and a number of precision engineering products with. Heat resistance, oil resistance, chemical resistance and good abrasion resistance, but also greatly reduce the water absorption rate of raw materials and shrinkage, has excellent dimensional stability and excellent mechanical strength.
Method for cutting thick glass
Some glass processing before processing, to the original piece of glass polishing, cutting, edge grinding, drilling, washing and drying process, such as tempered glass, laminated glass etc.; there are some glass processing technology, processing after washing and drying, and then according to the use requirements of cutting, grinding, grinding and polishing drilling and washing as final products, such as glass mirror; in addition to the art glass, such as painting, printmaking, relief, need specific processing technology, these are for cold working glass. The cold processing of glass is to process glass products into the required process by means of a series of processing methods at normal temperature.
Toughened glass and ordinary glass, process and raw materials what is the difference, a little more detailed, thank you
Toughened glass is the re processed product of ordinary glass.The main components in the glass is silicon dioxide, calcium oxide and sodium oxide, so called silicate glass. There are two ways to make glass toughened. They are physical tempered (air cooled steel) and chemical steel.Tempered glass adopts a chemical tempering method. The principle is the sodium ion with the "head" the larger potassium ions replace the glass surface "head" is small, so that the glass surface is a state, which is the formation of compressive stress, so that the glass has very high impact resistance (increased by about 5 times).
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).
Acrylic plexiglass rod can be used in what way?
Plexiglass sticks, which cheap plexiglass bonding is an important process, to enhance product quality and taste, affected by two aspects, one is adhesive; two is adhesive skills.
What are the main raw materials for making ceramics, glass and cement?
The main raw materials for glass production are quartz, feldspar (potassium feldspar, albite) and soda ash
What are the main materials for making glass?
Silica is the main raw material made of silica on the earth reserves is great. Silica is the main raw material for the main raw material is made of glass stones. The silicon content of different rocks are different. In our life of these materials is the most common.
