Man ester abbreviate inferior two phosphoric acids as: Inferior phosphoric acid esters, code name 304 T additive, belong to phosphorus very much pigeonhole and resists and rub the pharmaceutical by department. Because this products are pressed and resist the index of wasting high very much, it is good to lubricate compatibility performance with the foundation, The activation is too low to there is not side effect, use the easy and simple to handle merit of waiting for. And performance superior to chlorine department indexes, sulphur pigeonhole and resist and rub additive very much by department, push away lubricating oil circle, It is applying extensively to each low, of, high load machinery oils compound. This most early to develop and apply to the lubricating oil by Japan heavy chemical industrieses products, The additive code name is DBP - 1. The inferior phosphoric acid ester is the colourless or yellowish transparent liquid, not inflammable, difficult to explode , Easy to dissolve it in the organic solvent, chemical nature is extremely steady; Molecular formula C8H19O3P, structural formula: (C4H9O) 2 P \'s H molecular weight : 194, density: D200. 988, refract light 1 ND. 424, 120 Hs flash points, ≥ 14 of phosphorus content. 5%, according to the specification of the lubricating oil , difference of the type, use mixed, adding amounts are different to some extent too, It is 0 to generally consult the adding amount. 3~1%.
The inferior phosphoric acid ester is the colourless or yellowish transparent liquid, not inflammable, difficult to explode , Easy to dissolve it in the organic solvent, chemical nature is extremely steady; Molecular formula C8H19O3P, structural formula: (C4H9O) It add inferior phosphoric acid by esters and compound of different types hyperbola gear wheel oils, hydraulic pressure oil, press oil for less than steam turbine very much of at other additiveses, in, low, an high load gear wheel oil, Concoct, lubricating oil that become in gear wheel clench the teeth or the machineries of relative motion combine surface surface in load run China Economy high temperature, high pressure, Having formed the phosphorus ization membrane of more than one layer of effects, the composition of the membrane forms this kind of phosphorus ization, Wear and tear for organic phosphorus salt and inorganic phosphorus salt, thus lengthenned the gear wheel or parts service life , Have improved the life cycle of lubricating oil , make lubricating oil year load run for a long time , Do not change color , does not go bad . Its practibility, social benefit, the economic benefits are very considerable.
In strong nature who absorbs surface metal inferior phosphoric acid fats, press and it resists to be fine to rub performance very much and use response among modulating oil heavy activation producer at some, It is this products that slightly show and cause acidly, propose it while adopting other lubricating oil additive mainly, Choose low alkaline additives compound and compound and use, for instance the low alkaline petroleum iodineseses of quiet dispersants, Can reach the better result of reducing the activation too, this is transfered oil engineers and technicians to grasp flexibly . It is not inflammable, difficult to explode, the nonpoisonous and tasteless more convenient luck of chemical stability is stored and use. Because the inferior phosphoric acid ester can be concocted with the basic oil under the wanton temperature condition, Calculating the adding amount in visual specifications type of the special oil that are mixed, the proportion is large and very small, It concoct extremely kind performance compatibility performance, need and finish homogenizing only. When especially suitable for, allocate the producer use of the special oil small-scaly.
The inferior phosphoric acid ester receives the favors of the lubricating oil circle expert and the masses of engineers and technicians over the years because of having the above characteristic and performance , For a long time at irreplaceable first-selected positions, more and more at expert and engineers and technicians know its function hero, Giving play to function and glamour that the inferior phosphoric acid ester has alone . |
