What are the material requirements of the outer frame of Shanghai high temperature filter manufacturer?
Dust-free oven high temperature filter outer frame material requirements below 250℃ Optional aluminum profile frame, aluminum plate frame, galvanized frame, stainless steel frame; Galvanized frame or stainless steel frame must be used above 250℃. Sealant: red silicone (250~280℃).
Dust free ovenhigh temperature filtercan be selected with partition high temperature high efficiency filter, glass fiber bag high temperature filter F8, glass fiber high temperature filter.
Dust-free oven series is used in semiconductor manufacturing for silicon wafers, gallium arsenide, lithium niobate, glass and other materials before coating, coating film baking and high temperature baking after development; Also suitable for electronic liquid crystal display, LCD, CMOS, IS, medicine, laboratory and other production and scientific research departments; It can also be used for drying, heat treatment, aging and other high temperature tests of non-volatile and non-flammable and explosive goods.
Dust-free oven or oven to high efficiency air filter requirements are relatively high, the main reason is that the internal use of the environment is more sensitive to temperature, required to be used at a higher temperature, so we must choose this type of high efficiency filter.

The dust-free oven can be selected with partition high temperature resistant high efficiency filter, glass fiber bag high temperature resistant filter F8, glass fiber high temperature resistant shell is generally made of thin steel plate, the surface is painted, and the studio is made of high-quality structural steel plate. Aluminum silicate fibers are filled between the shell and the studio. The heater is installed on the bottom, but also on the top or sides.
Temperature control instrument adopts digital display intelligent table, PID adjustment: equipped with 999.99 hours time controller and connected with alarm device. Make oven operation more simple, quick and effective.
Dust-free oven high temperature filter is widely used in optoelectronics, electronics, electrical, communication, electroplating, plastics, machinery, pharmaceutical, food equipment and other precision baking, drying and shaping production lines.
The air temperature of the high temperature filter into the dust-free oven production line varies with the curing temperature, some as high as 200-400 ℃, because the heating device may produce dust and missing dust in the pipeline, the air filter is placed on the hot air end, which requires the temperature resistance of the filter itself to reach 200 ~ 400 ℃. So we should choose the requirements of high temperature resistance of the filter material is generally glass fiber, usually resin treatment products above 200 ℃, the temperature resistance of pure glass fiber can reach about 450 ℃.
High temperature resistant high efficiency filter using a partition design, corrugated partition can accurately maintain pleated layer spacing, under the minimum resistance, maximize the use of filter material, filter material on both sides of 180 fold fold fold layer, filter material bending when two indentation, so that the end of the partition open a wedge box fold layer, wedge box fold layer can prevent filter material damage.

Dust-free oven specialhigh temperature resistant high efficiency filterhas the following characteristics:
A, with partition high temperature resistant high efficiency filter frame optional: below 250℃ optional aluminum profile frame, aluminum plate frame, galvanized frame, stainless steel frame; Galvanized frame or stainless steel frame must be used above 250℃. Different frame material high efficiency filter price cost is also different.
B, optional thickness of aluminum profile: 120mm, 150mm, 220mm.
C. The filter material of high temperature resistant high efficiency filter with partition board is H13-H14 glass fiber filter paper.
D, sealant: red silicone (250-280℃) and ceramic glue (350-400℃).
E. The divider is 0.03mm thick aluminum foil.
Dust-free oven high temperature filter features:
1. Used in ordinary environment, it can ensure that the internal grade of oven reaches Class 100.
2, the whole week argon welding, high temperature resistant silica gel breaking, SUS304# stainless steel electric heater, prevent the machine itself produced dust;
3, the mining plane level from back to forward after the air supply through the United States imported H.E.P.A Filter 20″×20″ device front door (special air duct design) direction of air supply, filtration efficiency of 99.99%, Class 100, exhaust port: 3″φ(with automatic opening and closing air valve).
4, forced air circulation mode. Double duct circulation structure, uniform distribution of temperature field, intelligent P.I.D temperature control system, get the best temperature control precision.
Dustless oven high temperature filter maintenance requirements:
1, high temperature resistance high efficiency air filter surface black, accommodate more dust, resistance increases, that is, remove the non-woven fabric in the high efficiency air filter for cleaning, or replace.
2. Check the nozzle wind speed regularly (usually 1-2 times a year). If it does not meet the requirements of technical parameters, the high efficiency air filter should be replaced.
3, replacement, should pay attention to the new high efficiency air filter model specifications consistent with the original high efficiency air filter, high efficiency air filter for paper and wood structure, installation should be careful, do not fall frame, damage
4, replace the high efficiency air filter, must remove the nozzle flexible plate, take out the high efficiency air filter, replace the new high efficiency air filter, should pay attention to the high efficiency filter on the arrow sign, arrow
Pointing is the direction of the air flow.
5. After the replacement of the new high efficiency air filter, it must be confirmed that there is no leakage between the filter and the sealing material as well as the framework supporting the filter.
6. Check the electrical circuit regularly.
