Lubricating oil defoamer - easy to deal with the foam problem when metal processing
Lubricants are made from a combination of base oils and additives, and require straightening of the base oil, such as normal reduced pressure distillation, solvent refinement and dewaxing, propane de-asphalting, white clay refinement and hydrogenation refinement, before selecting the right additives for blending. Lube oil defoamer is a part of these additives, which can play an important role in the performance of lubricants.
What additives are added to the lubricant?
According to different process requirements, additives commonly used in the preparation of lubricants can be classified as lubricant defoamers, cleaning agents, dispersants, oily agents, antioxidants, rust inhibitors, anti-gumming agents, corrosion inhibitors, viscosity index improvers, etc. Here is a brief example of the purpose of adding these additives.
1. Defoamer: The compound is modified polyether, fluorine containing raw material, which can reduce or avoid the formation of foam of lubricant system.
2. Cleaning agent: The compound is sodium, calcium, magnesium and sulfonated material, which can avoid the surface deposition of lubricant after application.
3. Anti-wear agent: The compound is phosphorus, sulfur, CI compound, ZDDP, which can help to weaken the degree of mechanical friction and wear.
4. Antioxidant: Compounds are ZDDP, aromatic hydrocarbons, which can meet the needs of suppressing the oxidative decomposition of lubricants.
Lubricant defoamer properties and applications
Lubricating oil defoamer is a kind of appearance showing light yellow liquid, with excellent diffusivity and permeability, and all kinds of oil can be well soluble chemical additives. It can resist high temperature and pressure and high shear force, and can adapt to acid, alkali, salt, electrolyte and hard water, without affecting the basic nature of the foaming system.
Reasonable addition and use of lubricating oil defoamer can help to quickly eliminate the existing foam, and permanently stop the foam from rebounding, avoid environmental pollution and waste of resources caused by foam accumulation and overflow, improve the viscosity of lubricating oil, and make it maintain the proper anti-oxidation ability and low-temperature fluidity, etc.
