IP<sub>6</sub> metal corrosion inhibiter reachs cutting fluid

Steel of circumstance of change of surface of 1% test piece piece, cast-iron piece serious and rustily, sheet copper is spent gently become angry, aluminous piece slight pale steel piece, cast-iron piece without rust, if burnish is new; Sheet copper is slight loss of gloss, without rust; Aluminous a steel of slight loss of gloss piece, cast-iron piece, sheet copper, aluminous if a brightness is new IP6 has antirust function to part with the IP6 aqueous solution that adds certain amount macerate steel piece, cast-iron piece, sheet copper and aluminium piece, put into saturated vapor household utensils, check its antirust ability. Experiment condition and circumstance of change of test piece surface see a table inferior. Experimental structure makes clear, IP6 all has admirable antirust capacity to steel, cast-iron, copper, aluminium. PA water base cutting fluid IP6 is mixture of a kind of scarce pincers of much tine metal, with metallic complexing when, can preferential adsorption is in metallic surface, form compact hydrophoby diaphragm. Wait for activator of IP6 and mould inhibitor, lubricant, anti-foaming agent, surface according to afore-mentioned function make up PA water fund to belong to cutting fluid, have lubricate admirably. Cooling, catharsis is antirust wait for integrated function, its are basic the recipe sees a table 2. Basis GB6144-85 standard belongs to cutting fluid to undertake function assess to PA water fund, the result sees a table 3.

3xl0-4 corrodes an experiment (55+2 ℃ ) class immersion grey mouth of 45 ＃ steel is cast-iron 24h of LY12 red copper, class A 24h, class A 8h, eligible 8h, eligible 48h, class A 30h, class A 24h, eligible 24h, eligible rust-preventing characteristic experiments one class grey mouth is cast-iron (35+2 ℃ ) odd piece fold a 48h, class A 8h, eligible 48h, class A 16h, eligible IP6 is a kind of admirable water-solubility metal corrosion inhibiter, there all is good antirust performance to all sorts of metal stuff in water medium, can use extensively at metallic cutting fluid, in clear lotion, antirust. The PA that makes up with IP6 water base cutting fluid, its rust-preventing characteristic can be good, do not contain mineral oil, nitrite, the harmful material such as chromate, environmental protection free from contamination, be worth to be popularized energetically.
