Q:Can the wave heater heat the salt bag?: The light wave furnace is called the lightwave microwave oven. It is the biggest difference of the ordinary microwave oven, and lies in its heating mode. A wide range of ovens, used in brass or quartz tubes. Heating is difficult. After brass cools, it is easy to scald; and the heat efficiency of the quartz tube is not very high.

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.

Q:Why can quartz glass heating tubes be heated?: Not that it can be heated, but that it can be burned, and that the high temperature is not afraid of it

Q:The difference between quartz tube and far infrared tube in an electric oven: In the electric oven, the quartz tube is an electric heating tube made of quartz as the tube wall, and the red electric heating wire can be seen when heating.

Q:How to identify the trombone quartz stone: The process of tube for feeding, melting, forming, cooling, drawing. General quartz can slide, is the different quality requirements, if required, transparent no bubble, it should use silica of high purity, less gas-liquid inclusions of quartz stone, processed into high purity quartz sand to the trombone.

Q:The difference between infrared heating tube and quartz heating tube: Quartz heating tube is infrared heating pipe, heating pipe is not all but the infrared quartz tube, a far infrared coating metal tube tobo!

Q:What is the working principle of the electric heater of the quartz tube? Is the heating wire made of ordinary electric stove?: According to your description, it should be heated by semiconductor type electric heating film.

Q:Is the heating tube in the oven better quartz or stainless steel?: The quartz tube heating, usually by radiation heating objects, uniform heating, not in contact with the object to be heated, but it is difficult for local heating; and the stainless steel tube is through heat conduction heating, fast heating, is not easy to be uniform, but the local heating.

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:Quartz tube resistance to high temperatures, where is the difference?: Fused silica tubes are best able to withstand high temperatures and can last long below 1200 degrees Celsius, but they are soft at 1500 degrees centigrade.
