Multimeter before use must first check the quality of the multimeter; Adjust the dial of the multimeter to the AC voltage level "AC~" or "V~". Measure the socket in the room with the two markers respectively. If the voltage displayed is between 180 and 240V.......... Enter into detail

High purity quartz furnace products are special industrial technology glass made of high purity silica, which is a very good basic material. Quartz products have a series of excellent physical and chemical properties such as: 1. High temperature resistance. The softening point temperature of quartz glass is about 1730℃. It can be used at 1150℃ for a long time and the maximum temperature for a short time can reach 1450℃. ... Enter into detail.

In order to improve the service life of high purity corundum furnace tube and reduce the loss caused by damage caused by improper use, the following suggestions are put forward for users' reference: 1. The maximum use temperature of high purity corundum furnace tube should not exceed 1700℃, and the long-term use temperature should be below 1650℃. 2. The high temperature area of high purity corundum furnace tube should avoid mixing with impurities, especially metal debris and non-metallic mineral raw materials containing K2O, Na2O, CaO, SiO2, etc., otherwise it is easy to form low temperature eutectic and corundum tube damaged..........

Zirconia denture sintering furnace adopts silicon-molybdenum rod as the heating element. Due to the different components of zirconium block and dyeing agent added by various manufacturers, the zirconium block volatile matter in the high temperature state will cause damage to the protective film (SiO2) outside the heating element so that spalling, which causes discoloration and sintering not transparent..........

Equipment name: vacuum atmosphere box furnace, specification model: GWL-1700ZQLB500/300/300, furnace size mm (length width height) : 500×300×300, external size (mm) : 1000×850×1650, voltage AC

RTP rapid annealing furnace generally uses iodine tungsten lamp tube as heating element, heating speed is very fast, adopts S-type thermocouple temperature measurement and adopts the international ling's fuzzy PID control, has a high temperature control accuracy < ±5℃ >. Rapid annealing furnace with vacuum device, can work in a variety of atmospheres, greatly improve its range of use. Standard accessories: S type thermocouple 1, quartz inner and outer tube 1 set, vacuum flange 1 set, etc. 1. When the furnace is used again for the first time or for a long time (three months) after being stopped, it should be baked for 1 hour at about 120℃ and used for 2 hours after baking at about 300℃, so as not to cause cracking of the furnace. Furnace temperature should not exceed rated temperature, so as not to damage the heating element and furnace lining. It is forbidden to pour all kinds of liquid and dissolved metal directly into the furnace to keep the furnace clean. 2. The use of quartz tube, when the temperature is higher than 1000℃, the high temperature part of the quartz tube will appear opaque phenomenon, which is called permeability (also known as crystallization) is an inherent defect of fused quartz tube, is a normal phenomenon. 3. When cold furnace is used, because the furnace is cold, it must absorb a lot of heat, so the temperature rise rate of the low temperature section is not too fast, and the rise of each temperature section The difference in temperature rate is not easy to be too large, the physical and chemical properties of the sintered material should be fully considered when setting the temperature rate, so as to avoid the phenomenon of spraying material and pollution of the furnace tube. 4. Regularly check whether the contact of the electrical connection part of the temperature control system is good. Special attention should be paid to whether the connection of each connection point of the heating element is tight. 5. After the furnace has been used for a period of time, if the vacuum degree decreases, the temperature-resistant silicone ring between the stainless steel
