Semi-synthetic cutting fluid rust resistance problem, it is estimated that many manufacturers are more difficult problem, because the semi-synthetic cutting fluid is water-soluble cutting fluid belonging to the category of so-rust performance compared to cutting oil, the difference is still very large. General anti-rust performance to more than half of the semi-synthetic cutting fluid is rare, Henan lubricants Which is good, but cutting oil is normal. However, due to the cost of the above reasons, Henan lubricating oil investment, even if the anti-rust performance semi-synthetic cutting fluid has been lacking, most metalworking manufacturers also prefer semi-synthetic cutting fluid for cutting metal. And we need to introduce today is about if you provide semi-synthetic cutting fluid rust resistance, the choice of what kind of a rust inhibitor is more appropriate? Below we explain how we improve antirust performance semi-synthetic cutting fluid. Rust semi-synthetic cutting fluid, in order to reach more than six months, then we recommend the use of sodium nitrite and base as rust inhibitors, heated to 70-80 degrees, usually more than six months to achieve the anti-rust effect is no problem Henan motor oil, if the conditions allow it, add a little triethanolamine oleate soap, so rust-proof effect is even more perfect. For more on the semi-synthetic cutting fluid rust-proof performance improvement methods, only for rust on some of the high performance requirements of metalworking cutting factory, usually semi-synthetic cutting fluid, rust can reach three months, has been good. Lubricating oil viscosity for the normal operation of the engine is undoubtedly essential. In order to prevent contact surface wear between moving parts of the engine, the oil must have sufficient viscosity so that the film can be formed between the moving parts in a variety of operating temperature, Henan lubricating oil, so that the car engine running smoothly. However, the use of lubricating oil viscosity is too large then there will be at least two levels of the state. First, when the viscosity is too large degree higher than the impact of the time the engine is started, it is likely to cause severe engine wear at start-up. Since the lubricating oil viscosity is too large, slow-moving, hydraulic high, but by the amount of lubricating oil is not much, it can not replenish the friction surface. Oil circulation rate also slowed down its cooling and heat dissipation becomes poor, causing the engine to overheat. Since the lubricating oil circulation is slow, by the number of oil filters will become less, it is difficult to wear down in time to the late metal shavings, soot, dust cleaned out from the friction surface.
