Product Description:

Quartz Crucible


1. using high purity quartz sand(SIO2≥99.99%)

2. coated inner layer with strict defect control(foreign inclusions, bubbles, bubble clusters, scratches/scuffs, structure faults, spikes, vapor clouds…)

3. high thermal performance(strong heat resistance, high transmission)

4. customization available(custom design according to drawings)

We are manufacturer capable of producing quartz crucibles of varied sizes ranging from 6 to 24 inches.

Q:Can the quartz tube of the sterilizing cabinet be used on the heater?
The quartz tube electric heater is also called a halogen tube electric heater, and its heating body is an electric heating wire, which is worn in the quartz tube, and the quartz tube is supported, protected and exothermic. It uses far infrared quartz tube heating, and the heat transfer mode is radiation line. It has strong penetrating power.
Q:Why can quartz glass heating tubes be heated?
Heating or electric heating, just inside the quartz tube.
Q:Quartz heating tube and carbon fiber, which saves electricity?
Service life comparison: ordinary quartz heating tube has an operating life of less than an hour. The service life of carbon fiber heating tube is: hour.
Q:Which is more efficient, electromagnetic high frequency cooker and light wave oven?
In essence: light wave is the auxiliary function of microwave oven, only for barbecue. Without microwaves, the light wave oven is only equivalent to the ordinary oven. The light wave furnace in the market is a combination of light wave and microwave. In use, it can be operated by microwave, and can be operated by light wave alone. It can also be combined with light wave and microwave. That is to say, the light wave oven is compatible with the function of the microwave oven.
Q:What is the working principle of the electric heater of the quartz tube? Is the heating wire made of ordinary electric stove?
It is formed on the surface of insulator by thermal decomposition or magnetron sputtering or evaporation by special electronic paste at high temperature
Q:Can the electric heating wire in the quartz tube be replaced by an electric tungsten wire?
Divided into civilian and industrial use.For civilian use, mainly for heaters and light wave furnaces.For those who need almost industrial heating industry: printing and dyeing, footwear, coating, food, electronics, medicine, textile, wood, paper, plastics, automotive, furniture, metal, heat treatment, packaging machinery and so on.The far infrared heating tube has the characteristics of high density, high heat efficiency and low energy consumption. Using this tube as a heater, heating element oven etc heating equipment than ordinary infrared heating can greatly improve work efficiency, shorten the heating cycle, saving equipment space, save energy, reduce the production cost.
Q:Vacuum sealing problem of quartz tube
The above method is expensive, in fact if you want cheaper just to find a point of the quartz tube can be, the top of epithelial tube can vacuum. Quartz insulation is still relatively good, your working temperature was 500 degrees, then the head end of the temperature can only 40-50 degrees, with no consideration this is cool. Hundreds of pieces of fix.
Q:What is the difference between the performance of the quartz ozone tube and the ceramic ozone tube?
Quartz discharge tubes are usedThe quartz discharge tube is open type, the ozone equipment is equipped with a large air volume blower, and the ozone diffusion is fast, and the quick sterilization effect is achieved. The quartz discharge tube is more suitable for large space use, and the ozone generator has large gas consumption and relatively good bactericidal effect
Q:Which is better, quartz glass heating tube and PTC heating tube?
Of course, the PTC ceramic heater is better. Leak easily burst quartz tube, now basically eliminated, PTC is not comparable to other heater heater, PTC heater insulation and high safety, high heat energy conversion efficiency, but also comes with constant temperature function, not because of overheating protector failure under the condition of burning, this is no other heater, the most unsafe is the quartz tube and the heating wire heater
Q:What are the defects of the ceramic heater and quartz tube heating?
The ceramic PTC has high heating efficiency and no open flame, and the hot air circulation flows out heat energy to the space.
