the conveying chain of reflow furnace, plate width adjusting screw rod and other parts need to work at a high temperature above 200 ℃, The temperature in a specific area of the welding furnace is 250 ℃ or higher
At present, the lubricants widely used in the industry, such as polyphenylene ether, perfluoropolyether, methyl silicone oil, methyl phenyl silicone oil, etc
, even the widely publicized products added with various high-temperature additives, have many problems in the lubrication of high-temperature parts of reflow furnace
The problems after using these greases are: L the grease is easy to dry, and the grease will form carbon at high temperature, The accumulation of carbon deposits will make abnormal noise, and it is difficult to adjust the plate width until the chain and screw rod are stuck and locked, forcing the equipment to shut down for maintenance L excessive wear caused by large amount of grease volatilization and insufficient lubrication, which forces the equipment to overhaul in advance , L the grease will drop oil at high temperature, and the oil with weak adhesion at high temperature will crawl along the chain until the circuit board is polluted, the LSMT plant is sealed, and the air flow is small
The volatile and thermally decomposable components of the oil evaporated at high temperature cannot be discharged in time through the air duct of the welding furnace
These components and various lubricating oil additives accumulate in the air over time, which will be detrimental to the health of the operators L the welding furnace adds oil / grease to the chain and screw every month, which is very troublesome
The competition in the electronics industry is very fierce, so the SMT lines of many factories operate 24 hours a day, six to six and a half days a week
In the case of tight delivery date, it is also common to drive continuously for half a month
During the lubrication and maintenance of the plate width adjusting screw rod and chain of the high-temperature parts of the reflow furnace, the welding furnace shall be opened to interrupt the production
If the manufacturer uses the extremely limited maintenance time for the weekly lubrication of the welding furnace, it is undoubtedly not worth it
However, abandoning the maintenance will reduce the service life of the equipment

  In order to ensure long-term trouble free operation of reflow furnace and reduce unnecessary maintenance workload of reflow furnace, appropriate high-temperature lubrication method must be selected WS2 solid high temperature resistant lubricating film is an American high-tech product exclusively introduced by our company
It is successfully developed to cooperate with the space program of NASA (National Aeronautics and Space Administration)
Now it has been widely used in the field of mechanical equipment
It has the following advantages: 1, Extremely high lubricating performance
  The friction coefficient of WS2 on the metal surface is very low, only 0
03, so it can increase the key Reduce the service life of parts and components, reduce maintenance downtime and maintenance costs

2、  High temperature resistance, no oil dripping and no carbon deposition
  WS2 has extremely high chemical stability
It can withstand high temperature up to 650 ℃ and does not react with oxidation
Excellent lubrication effect can be maintained at high temperature of 650 ℃ and low temperature of - 273 ℃
It can be used continuously for a long time at 288 ℃ without carbonization
The high-temperature chain does not need to be cleaned within its service life
WS2 will not drop oil at high temperature and will not affect product quality

3、  Conducive to environmental protection
WS2 is a solid substance with no flash point and no combustion hazard
This product has passed SGS certification and conforms to the most authoritative hazardous substance detection standard Huai (RoHS) in the world
Therefore, the impact on the health of operating employees and the understanding of environmental pollution are reduced

4、  No impact on product quality: WS2 film is only 0
5 μ m and will not bring any shape change to the parts

  5、  Reducing fire hazards is particularly important for welding furnaces without nitrogen protection WS2 is undoubtedly very suitable for the lubrication of high-temperature parts of reflow furnace and more suitable for the strict requirements of environmental protection and product quality in the future
With the improvement of science and technology and management level, WS2 will be more and more widely used in reflow furnace
