Quartz glass is a single-component amorphous material of silica. Its microstructure is a simple network composed of silica tetrahedral structural units. Due to the large chemical bond energy of Si-O, the structure is very tight, so quartz glass It has unique properties, especially transparent quartz glass, which has excellent optical properties and excellent transmittance in the continuous wavelength range from ultraviolet to infrared radiation.
Quartz glass uses high-purity silica sand as a raw material. The traditional method of fabrication is the melt-quench method (heating the material to the melting temperature and then rapidly cooling to the solid phase of the glass); making transparent glass with ultra-high purity and UV transmittance requires silicon. The process of vaporization, oxidation into silica and heating and dissolution. [2]
Form use
The formation of quartz glass is a result of the high viscosity of the melt. Used in the manufacture of semiconductors, electric light sources, semi-conductive communication devices, lasers, optical instruments, laboratory instruments, electrical equipment, medical equipment and chemical instruments resistant to high temperature and corrosion, chemical, electronics, metallurgy, building materials and national defense industries, applications Very extensive.
High-purity quartz glass can be used to make optical fibers.
With the development of semiconductor technology, quartz glass is widely used in various processes of semiconductor production. For example, the Czochralski method converts polycrystals into single crystal silicon; the cleaning bath used for cleaning; the diffusion tube used for diffusion, the grooved boat; the bell jar used for ion implantation, and the like.
Wall spikes are just one of a number of types of anti climb security spike and whilst the name Wall Spike indicates that they are designed to be mounted on a wall (typically along the top edge), they can often also be found welded or otherwise fixed along the top of steel gates and robust fences.
Popular types of wall spikes include big type wall spikes and medium type wall spikes and small type wall spikes, with the spikes being manufactured from a range of materials including weather resistant plastics, steel and aluminum, among others.
Features:
materials: hot dipped galvanized, stainless steel, PVC coated plates.
Plate thickness: small type spikes with 1mm, and other wall spikes with 2.0mm.
