NYlon6 and nylon66 Air Covered Yarn and Conventional Covered Yarn

Q: Water glass, ceramics, ordinary cement, quartz glass, what are these chemicals?: The main component of these substances, ceramics, cement, and quartz, is SiO2. In addition, SiO2 is also used to make optical fibers.Elemental silicon is used to make solar panels, chips and other materials

Q: Twilight wall hollow glass with glass Zha glue with what is best?: The raw materials of the latter two kinds of insulating glass are glass, aluminium strip, insert angle, butyl glue, double component polysulfide glue or silicone rubber, drying agent and compound sealant.

Q: What is the glass DV board made of?.: Glass is formed by melting sand with other chemicals (the main ingredients are: soda ash, limestone, quartz). A continuous network structure is formed during melting, and the silicate like non-metallic material is gradually increased and hardened in the process of cooling.

Q: Long plastic soft glass is a food grade raw materials?: The normal use of the family (including the dining table) is entirely without question

Q: Glass factory raw materials specific to do?: Glass is formed by melting sand with other chemicals (the main ingredients are: soda ash, limestone, quartz). A continuous network structure is formed during melting, and the silicate like non-metallic material is gradually increased and hardened in the process of cooling. 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. There is also colored glass mixed with certain metal oxides or salts, and toughened glass made by special methods. Sometimes some transparent plastic (such as polymethyl methacrylate) is also called organic glass.

Q: Not man-made destruction, why toughened glass suddenly broken?: There are a variety of predisposing factors 2. tempered glass explodeFor example, A. before the installation of glass is accidentally damaged, like chipping, knocked the feet, because the glass is tempered around the weak area, its strength even weaker than the non tempered glass, but this part of the damage are not likely to cause the glass immediately burst, but changed the internal stress of glass. When the upper wall is used, the internal stress changes gradually, which breaks the glass.B. such as differences in temperature after installation. As you say, temperature, weather, and so on, will make the internal pressure of the glass partial uneven, thus causing burst.Is there a correct size for the C. installation?. If the installation is too tight, the specifications are not appropriate, it will cause stress changes inside the glass, causing a burst.D. the rest is external force, including impact, extrusion and so on. It's not just human impact, or other things, or even wind in nature. If the glass does not fall on the ground, there will be the point of impact (if it is obvious, there will be explosive, Hu Dieban) these can be invoked, but if in the proceedings can only be said to be a possibility, because you have no evidence to prove that. In the domestic situation, the glass manufacturers generally compensate for the glass trouble.

Q: How can the vacuum tubes of solar water heaters be chromatic aberration? Is purple good or sky blue good?: Fundamental difference: the structure of the film is different, resulting in the principle of absorbing solar rays is not the same. As a multilayer film, the absorption layer is usually 9 layers. It absorbs the solar rays by layer by layer, and absorbs the light gradually. As a result of this gradient structure, the emission ratio increases with the increase of temperature, so that when the working temperature is 300~500 degrees centigrade, the emissivity ratio increases greatly. Moreover, the aluminum ions in the absorption layer are greatly enhanced and shifted at high temperature. In this way, the internal structure of the film is disordered, leading to the aging of the film. At this high temperature for a long time, the film will fall off, thus affecting the heat collection efficiency and life of the vacuum tube.

Q: How to identify and select high quality insulating glass?: At present, there are three kinds of insulating glass in China: (1) groove aluminum type single channel sealing; (two) groove aluminum double channel sealing; (three) compound sealant strip type insulating glass. Groove type aluminum single channel seal, because of its poor sealing, easy to enter moisture, resulting in condensation of glass, frosting, short service life, so the kind of insulating glass gradually eliminated.

Q: How do I see whether the raw material of tempered glass is made of float glass or standard glass?!: Float glass: float glass surface flat, good brightness, no bubble and tumorLattice glass: the surface of the lattice is not very smooth, and the ripples can be seen from the side. Uneven thickness

Q: Mobile phone film new flexible toughened glass membrane, really is the glass?: Tempered glass (Temperedglass/Reinforcedglass) belongs to safety glass. Glass has a fairly good abrasion resistance and is very hard, with a Vivtorinox hardness of 622 to 701.
