Quartz Glass Boat

1.Temperature : softening point temperature of about 1730 degrees celsius , 1100 degrees celsius in a long time use , short-term maximum temperature up to 1450 degrees celsius ; 2.Anti-corrosion : in addition to hydrofluoric acid , is an almost non-acid and other substances a chemical reaction , especially in the high temperature chemical stability is in any other engineering materials can not be compared; 3.Thermal stability :the thermal expansion coefficient of quartz glass , is extremely small , able to withstand drastic temperature changes ; 4.Transmittance good performance :quartz glass in the entire ultraviolet to infrared spectral bands have a good light transmission properties, visible light transmittance of 93% or more , especially in the ultraviolet spectral region , the largest up to 80% or more transmittance. Standard export packing

Quartz raw materials and the oxyhydrogen flame producing quartz glass, several tens of ppm of metal-containing impurities. Absorption peak (hydroxyl content 100-200ppm) at 2730nm at streaks and particle structure. It is through the wavelength range within 220-2500m good material.

1. Transparent quartz glass tube Smooth, colorless and transparent, high purity íí(sio2í¦99.99%), corrosion-resistant (expect hydrofluoric acid), high temperature-resistant (intenerating point 1730íµ), good thermal-stability, good light-penetrability (over 93% of visible light), crystal capability(6 hour under the temperature 1400í+5íµ,crystal thickness is less than 100 micron), good insulating-ability, long-life and non-contaminative. Mainly used in protection of heaters, production of halogen tube, lamps. 2. Desoxy transparent quartz tube Nice appearance, good thermal property and mechanical strength, strict tolerance and low hydro-(í_5ppm).Used in mercury lamp, metal halite and other quartz lamps. 3. Non-ozone transparent quartz tube It can prevent high-density ultraviolet radiation by being added titanium-oxide with colorless surface and light-purple section. It can almost prevent ultraviolet radiation no more than 220nm, while penetrates over 83% of 253.7nm, which have strong bactericidal ability. So ití»s called "bactericidal" and "non-ozone" quartz. It is widely used in bactericidal lamp, treatment of water and so on. 4. Uv-filtering transparent quartz tube It has colorless or light-blue surface and light-purple section. Besides common property, it can filter ultraviolet radiation of 190-320nm to prevent harm to bodies. It can be used in most kinds of environmental lighting products.

1. The milk-white (pearl-white) quartz glass tube can be manufactured into different shape as circle, pear, u and so on. 2. Normal quartz heating tube Never be eroded, good insulating ability, safely used, fast falling of temperature, save energy. Used in sterilizing dresser, microwave oven, drinking fountain and some other home appliances. 3. Far infrared halogen lamps: Our halogen lamps are all made by ourselves including tungsten filament- twisting and shell producing. The output is up to 3000-5000pcs/month. They are mainly used in room heating and industrial baking. The using life is over 5000 hours with good appearance and high quality. They can be manufactured into different shape as straight, round, circle, u and so on. All the products are made with fine tungsten filament as heating element, different quartz glass tube (transparent, uv, colored, milk-white) as shell, and filled halogen-tungsten gas to prolong the life.

Opaque quartz glass tube With the adoption of distinctive technique, our opaque quartz glass tube has its typical characteristics of good visual aspects and stable physical &chemical properties. It serves as material of infrared heating for heaters, micro-wave oven, electrical baking oven, car paint baking, steriliztion container and other consumptive and industrial infrared application. Further processing of trim cutting, bowing, firepolishing can be done according to the demanding of the customers. Carton

Translucent quartz glass tube They are clean and smooth, high purity (si02fª99.8%), stand cautery (expect hydrofluoric acid), stand high temperatrure (intenerate point 1650), good heat stablity, good transmition (even at infrared spectrum), insulated well, long life and without pollution. Mainly used in kinds of far infrared heating and drying facilities.

Dark-red and golden quartz tube is a new kind of quartz material. Compared with common transparent quartz, it can absorb uv and most visible light and translate into infrared radiation. Compared with milk-white quartz, it can penetrate infrared radiation, which can load several times of energy per area. Compared with coated quartz, it is low-cost and high-stability. So it is an excellent material for producing infrared heater. Ití»s suitable for high-power and small-volume infrared heating products.

1.High softening point; 2.3.3 co-efficient of expansion; 3.180 thermal shock resistance; 4.Reasonable price with good quality
