Large-diameter quartz tube is a kind of special industrial production technology laminated glass made of silica, with high-quality physical and organic chemical properties, and is widely used in energy-saving lamps, semiconductor materials, optical fiber communication, military, metallurgical industry, decorative building materials, organic chemistry, machinery and equipment, power engineering, environmental protection and other fields.

Due to its valuable and fragile material, it is necessary to pay special attention to the following points when using it to ensure its optimum performance and extended service life.

1. Precautions during handling and installation

Large-diameter quartz pipes are valuable materials and fragile, so they must be handled with care during handling and installation to prevent cracking. When moving and storing quartz pipes, large vibrations and squeezes should be avoided to prevent damage caused by external forces. In addition, pinching one end of the quartz pipe with one hand can easily cause it to bend and break, so you should hold it with both hands to ensure the safety of the quartz pipe.

2. Cleaning and pretreatment

For large-diameter quartz tubes that need to be used at high temperatures, they must be wiped clean before use. It can be soaked in 10% hydrofluoric acid or lotion, and then washed with high-purity water or treated with alcohol. During operation, thin-line gloves should be worn to avoid direct contact with the quartz tube by hand to prevent oil and sweat from contaminating the quartz tube from affecting the use effect.

3. Avoid contact with alkaline substances

Large-diameter quartz tubes are acidic materials, and they should be used at high temperatures to avoid contact with alkaline substances (such as water glass, asbestos, potassium and sodium compounds, etc.), otherwise their anti-crystallization properties will be greatly reduced.

4. Precautions when using at high temperatures

Large-diameter quartz tubes have high thermal stability and can withstand severe temperature changes. However, due to differences in residual strain and product shape, the thermal stability during actual use may vary, and attention should be paid when using them. Continuous use of quartz tubes is allowed at high temperatures, which is beneficial for prolonging the life of large-diameter quartz tubes and improving temperature resistance. On the contrary, intermittent use of large-diameter quartz tube products at high temperatures has a limited number of uses.

5. Temperature control

All kinds of large-diameter quartz tubes have a high operating temperature, which should not be exceeded when used, otherwise it will crystallize or soften and deform. The softening point temperature of quartz glass is about 1730 ° C, which can be used for a long time at 1100 ° C, and the temperature can reach 1450 ° C in the short term. Therefore, during use, the temperature must be strictly controlled to avoid exceeding the maximum operating temperature of quartz tubes.

6. Other considerations during installation and use

Avoid rigid force fixation: Quartz pipes should be avoided during installation and sufficient clearance should be left to allow for thermal expansion during heating.

Maintain proper inclination: The inclination of the heating tube when installed horizontally should be controlled within 30 degrees to ensure safety during the heating process.

Lead installation requires caution: When installing the heating tube power supply lead, a high-temperature insulating ceramic sleeve or glass fiber tube should be fitted as much as possible to avoid the risk of leakage.

Regular cleaning: After the electric heating pipe has been in use for a period of time, if thick pipe scale and grease accumulate on the surface, it should be removed regularly to ensure its heat transfer performance.

7. Storage and maintenance

Large-diameter quartz tubes should be stored in a dry warehouse to prevent moisture. If the surface is damp due to long-term placement, the insulation resistance should be measured with a megohmmeter before use. If it is less than 1 trillion ohms/500 volts, the quartz tube should be placed in a 200-degree drying oven for drying or reducing the voltage and heating until the insulation resistance is restored.

As a high-quality basic raw material, large-diameter quartz tube has high-quality characteristics such as heat resistance, corrosion resistance, good light transmission performance, and good insulation performance. However, due to its valuable and fragile material, special attention needs to be paid to handling, installation, cleaning, temperature control and other aspects when using it. By following the above recommendations, the best performance and extended service life of large-diameter quartz tube can be ensured, providing reliable protection for various industrial applications.
