1. Why is cyclohexane oil the "C position" of emulsified oil? Cyclohexane oil is naturally equipped with a buff: High aromatic content makes it "love at first sight" with emulsifiers, and the emulsified oil prepared has good stability and strong rust resistance, which is really easy to use in metalworking fluids.
But! This does not mean that it is the "only option"!
2. No cyclohexane oil? Four alternatives are unboxed and tested!
Plan A: Paraffin-based oil + polar additives (low cost, suitable for scenes with low rust prevention requirements) Operation guide: Choose low-viscosity paraffin oil as the base, add 3-5% sulfonate emulsifier (such as T702), and add 0.5% succinic anhydride to assist in blindness. Measured data: A tool factory switched to this formula, and the emulsion was left standing for 24 hours without stratification, but the anti-rust cycle was 15% shorter than the cyclohexane oil formula, which is suitable for workpieces that are quickly cleaned after processing.
Plan B: Score synthetic ester oil (good performance, but your wallet has to bear it) Hardcore advantage: Diester/polyol ester has its own polar group, emulsification speed is 30% faster than cyclohexane oil, and it also comes with lubricity bonus! Tips to avoid pitfalls: pH value sensitive! It is recommended to use a non-ionic emulsifier (such as OP-10) to avoid saponification stratification. A bearing factory uses pentaerythritol ester to adjust the emulsion, and the speed of the production line is directly increased by 20%.
Plan C: Vegetable oil "counterattack" (environmental protection policy is tight, this wave is not a loss) Magic operation: Rapeseed oil is modified + nano-alumina particles, the emulsification stability is improved!
Plan D: Use 2300 emulsified oil compound (pure oil type, water-free formula) Usage guide: 2300 emulsified oil compound + 150SN/150N base oil = 2300 emulsified oil finished liquid is suitable for processing ferrous metal materials such as mold steel, high carbon steel, 45# steel, cast iron, stainless steel, etc. It has good rust prevention, emulsion stability, excellent cleaning performance, etc.
3. Secrets of oil blending veterans Emulsification stability self-test : Pour the prepared emulsion into a transparent bottle, freeze it in the refrigerator for 2 hours and then warm it up. It is considered passed if there is no stratification after 3 cycles. Anti-rust first aid kit : Add 0.3% benzotriazole to extend the anti-rust period immediately. Ultimate money-saving technique : Paraffin oil + synthetic ester 7:3 mix, the cost is reduced by 25%, and the performance can still be guaranteed by 80%!
