Product Features of Clear Quartz Tubes

These tubes advantages are high purity, good spectral transmission, well controlled dimension and low OH, etc.
They're the best heat resisting material for lamps like: halogen lamps, mercury lamps, metal halide lamps, etc.
We can produce the tubes within a very large diameter rang: OD 3-400mm, thickness wall 0.7 – 10.0mm , length maximum 3000mm.
We also can apply some further processing like trim cutting, fire polishing, bending, pinching, grinding and others according to customers’ requirements.
We also can control our tubes OH content within 20ppm\ 15ppm\10ppm\5ppm\2ppm as your special needs.

Clear Quartz Tubes

Q:Excuse me, what is the raw material of quartz tube drawing, can say the best raw materials in quartz tube: Quartz tube is divided into many varieties, but the raw material is mainly natural quartz ore, which is divided into crystal and silica according to the ore morphology.

Q:Is the heater good for quartz tube or electric heating wire?: The quartz tube is not Quan heat, which is electrothermal radiation, Lei through the quartz tube, the heat radiation than the set of quartz tube heat. Direct heating wire is now selling up Lei, such as coated with far infrared coating, Quan heat is not bad. The best heating element, PTC ceramic, according to my conditions and preferences in the three choice.

Q:Disinfection cabinet light wave or quartz tube good?: Personally feel that the quartz tube is good, high temperature, but brightness is not very large, will not be very dazzling said!

Q:What is the role of quartz glass tube?: The biggest difference between the quartz glass and ordinary glass is heat level, quartz glass can resist to your unexpected temperature, such as burning in the fire immediately after not burst into the water!

Q:How can the quartz glass tube be butted with stainless steel?: The temperature is not high, the use of epoxy resin or silicone rubber adhesion, high temperature should use inorganic high temperature glue (copper oxide + phosphoric acid), the requirements are not high, you can directly cooperate with.

Q:Does the quartz tube have no open flame?: The ceramic PTC has high heating efficiency and no open flame, and the hot air circulation flows out heat energy to the space.

Q:Which is better, quartz glass heating tube and PTC heating tube?: PTC is a relatively new heating material with no thermal expansion coefficient and fast heating, but the heat transfer is slower than the quartz tube under the influence of efficiency.

Q:Quartz tube heater principle: Far infrared heating tube is used by the opal quartz glass tube, with special processing of resistance alloy material as a heating element, the opal quartz glass can be absorbed into the electric wire from radiation almost all of the visible light and near infrared light, and can make the far infrared radiation. But the current industrial infrared heating tube basically eliminates the milky white quartz tube, because of its relatively brittle material, it can not form a very long white heating tube. The milky white has an anti - light effect that stops its heat. Because of its high wall temperature, it is only suitable for near infrared heating.

Q:Can quartz tubes be used in a vacuum tube furnace of 1300 degrees?: LTKC-5-12 vacuum tube furnace, quartz tube standard temperature resistance is 1200 degrees, programmable energy-saving tube furnace, LTKC-4-13 quartz furnace tube, temperature resistance can reach 1300 degrees

Q:Is the light wave harmful to the body?: Light wave furnace is also called light wave microwave oven. The biggest difference between it and ordinary microwave oven lies in its heating mode. The ordinary microwave oven, the inner barbecue pipe, generally uses the copper tube or the quartz tube. It is difficult to cool the copper tube after heating, which leads to scalding. The heat effect of the quartz tube is not very high.

Our company has advanced production lines, strong technical force, and USES the unique production technology, production of various specifications of the transparent quartz glass products. Company main products are high purity, low hydroxyl quartz tube, quartz glass tube (rod), filter uv quartz tube, etc. Products are mainly used in the production of automotive bladder hernia headlight, metal halide lamp bladder, uhp lighting. Our company production of quartz glass by vacuum removing hydroxyl hydroxyl furnace processing, hydroxyl content can be up to 2 parts per million
