Opens at high temperature impact bearing rust do, teach you a few high temperature bearing antirust processing method 1)
Looks like cleaning: cleaning work is required in accordance with the rust appearance and condition at that time, the properties of the selected an appropriate way.
Ordinary enterprises commonly used solvent cleaning, chemical cleaning and mechanical cleaning equipment disposal development.
2)
Appearance after dry cleaning clean available filtering squeeze air blow dry, boring or use 120 ~ 170 ℃ boring machine stop boring, also can use clean dry gauze.
Coating anticorrosive oil way: impregnation method: some small items in antirust oil, on its surface coated with a layer of anti-rust oil.
By controlling the anti-rust oil temperature or viscosity can reach the thickness of oil film.
2)
Use brush method is not applicable to soaking or spraying outdoor engineering construction technology and equipment or special structure shape of the products, when the brush should not only pay attention to do not produce a large number of accumulation, also want to pay attention to enterprise to avoid leakage.
3)
Spray some countries heavy rust cannot oil by means of different immersion method, ordinary about 0.
7 mpa pressure filtration squeeze air clean development the central government to stop spraying in air environment.
Spray method used solvent XiShiXing rust-proof oil or thin layer of anti-rust oil, but must study used a perfect fire protection and labor relationship maintenance and management measures.
What is the main factors influencing the bearing what high temperature corrosion?
High temperature corrosion influence bearing is composed of enterprise internal and external factors, provoked by the research, in the aggregate, mainly include: the chemical composition and structure of high temperature bearing data;
High temperature bearing surface brightness (
The oxygen concentration cell corrosion)
;
(3) combination, as well as described in the bearing temperature outside contact with the pH of the solution;
(4) environmental temperature and humidity;
5. Contact with high temperature bearing in appearance of various environmental medium.
Why would hand sweat provoked high temperature influence bearing rust?
Human body sweat is salty colorless or light yellow liquid weak acid, its pH 5?
6 besides containing sodium, potassium, calcium, magnesium salt, urea, but also contains a small amount of lactic acid and citric acid.
When contact with sweat high temperature bearing, will constitute a thin film layer of sweat, sweat bearing membrane can lead to electrochemical reaction temperature, bearing temperature corrosion under high temperature bearing.
People sweat is inevitable, in order to prevent from hand sweat corrosion, consumers should have the gloves, the fingers or pick up the part with special tools, shall not touch the product.
High temperature bearing rust what method?
Commonly used methods of rust, it is a 'clothes' - iron and wear
By external iron plating or other high temperature bearing picture is not easy to rust, for example, cars dressed in luster paint;
Heating tube.
Coated aluminum paint;
Tin tin tin layer;
Zinc town of tin on the roof of the outer layer;
。
A more thorough way you pen, with chrome or nickel plating layer, alloy for other high temperature bearing, made of stainless steel alloy, famous for nickel and aluminum and steel -
Used for injecting iron 'booster.
'Rust should be aimed at our country the cause of the high temperature bearing corrosion can take some appropriate measures.
Commonly used way to have:
Bearing temperature changes within the organizational structure]
, for example, all kinds of corrosion resistant alloys, such as participate in chromium, nickel in stainless steel in ordinary steel.
