Selection of antirust oil for steel wire
January 05, 2023
There are many kinds of antirust oil for steel wire, which one is more suitable for the use of products? What should be considered when selecting steel wire antirust oil?
(1) Need to know the material and surface state of rust proof products; Different antirust oils have different antirust effects on different metal materials. Some of them have good antirust effects on ferrous metals, but the effect on copper is average. These are often described in the product description of antirust oils, which should be selected carefully. (2) Need to know the size and shape of anti rust products; According to the structure and size of the product, solvent dilution type or grease type can be selected for simple structure and large surface area, while oil type with complex structure and holes or cavities is better, because the removal of antirust film during unsealing should also be considered. (3) Oiling method The oiling method shall be hot or cold according to immersion, spraying or spraying. (4) Type of oil film The oil film is a dry film, oily film, soft film or semi dry film. Any requirements on film thickness, whether it is a film or a lipid film, need to be understood in advance. (5) Is the surface clean and dry before applying antirust oil? Before applying antirust oil, confirm whether the cleaning condition of the product surface meets the requirements of the selected antirust oil. (6) Packaging, storage and transportation conditions after applying antirust oil; According to the packaging, environment and purpose of the steel wire, we can distinguish whether it is short-term process rust prevention or long-term rust prevention with short-term lubrication, long-term storage rust prevention for humid environment, or it may be stored in coastal warehouses or even for a certain period of marine transportation, so it has good salt spray resistance. The selection should be targeted in this regard. (7) Source and price of rust preventive oil.
Comprehensively consider the above aspects The steel wire should preferably be coated with soft film or oily film antirust oil soft film at normal temperature (10~35 ℃) or medium temperature (no more than 70 ℃): the commercial steel wire can be cold coated with L-RE (film thickness ≤ 50um) and L-REE-1 (film thickness ≤ 25pum) in solvent diluted antirust oil, which are generally not affected by the environmental temperature and can be selected as required. If the film thickness is less than 12.5 pm, it is an ultrathin film. The membrane is too thin and requires a large amount of gasoline, kerosene and other solvents, which is not conducive to safety and environmental protection due to large volatilization. When it is open to use, the oil will be continuously concentrated, which will change the film thickness. Oily film: Select the lubricating antirust oil with viscosity L-RD-1, low viscosity L-RD-2 and L-RD-3, or select the solvent diluted antirust oil with viscosity L-REE-2. As the viscosity of oily film Base Oil increases with the decrease of ambient temperature, the oil film thickens, and the excess oil will be lost and pollute the environment due to the increase of ambient temperature, so the oil temperature should be better controlled at 35~65 ℃. The steel wire rope shall be coated with L-RK grease antirust oil. The antirust period of sealed antirust oil is generally 0.5 to 3 years for metal with clean surface, which can be selected according to product requirements. Valuable, fine, rusty steel wire with poor storage and transportation environment should be sealed with rust preventative oil with high content of rust inhibitor and excellent performance. The steel wire with low requirements for annealing, phosphating or plating treatment can be sealed with general antirust oil.
