Humid test and humid test is adopted to carry out performance test comparison to above-described embodiment powdered lubricant and common lubricant powder respectively.
Humid test: the powdered lubricant of the various embodiments described above and common lubricant powder sample are laid in desiccation culture ware, in the temperature and humidity regulator being placed in temperature 50 C and relative humidity about 90% 1 week, observes the metamorphosis of sample in culture dish.
Humid test: the powdered lubricant of the various embodiments described above and common lubricant powder sample are placed in dry crucible, and the loft drier interior heating 2h being placed in temperature 200 DEG C, observe the metamorphosis of sample in crucible.
Caking rate measures: the powdered lubricant got after 10g test is placed in beaker, add boiling water to 100mL, abundant stirring, leave standstill, powdered lubricant solution is crossed micro-mesh (5 μm, aperture), screen overflow is dried, weigh, calculate the caking rate % of powdered lubricant, calculation formula is: caking rate %=m/10 × 100%, and wherein m is the quality of the upper drying object of sieve.Test-results is as shown in table 1, wherein, ▲ representing that caking is serious, △ represents a small amount of caking, zero-represent substantially without caking.
Table 1: test-results
The above results illustrates, powdered lubricant of the present invention both can prevent powdered lubricant from producing caking by the synergistic function between raw material, can improve again the lubricity of powdered lubricant simultaneously.Powdered lubricant provided by the invention is suitable for various steel wire and carries out the large rate of compression dry drawing of high speed, test proves in a particular application, mould loss is reduced to 1.2 ~ 1.8 pieces/10t from 3 ~ 3.5 pieces/10t, wire broken rate is reduced to 1 ~ 2.5 time/100t from 5 ~ 8 times/100t, and the Steel Wire Surface after drawing is without defects such as scuffings.
Agglomeration resistance mechanism of the present invention is: due under normal shelf and production plant environment, powdered lubricant can absorb moisture gradually, make powder granule surface that deliquescence occur, in basic powder, the water-retaining agent of interpolation, as layered sodium disilicate, there is the effect of mechanical isolation and absorbing particles surface-moisture, prevent the brilliant bridge of intercrystalline to be formed, and this material have laminate structure, improves lubrication; In addition, steel wire is when drawing, and steel wire produces a large amount of heats with the mutual friction of mould phase, by adding heat absorbent, as sodium bicarbonate etc., decomposes, can absorb heat during decomposition, reduce the temperature around basic powder, play from cooling effect, also reduce powdered lubricant simultaneously and burn the possibility with caking.Sodium bicarbonate decomposes generation carbonic acid gas and water vapor gas simultaneously, can destroy intercrystalline bonding, suppresses caking generation further; Further, extreme-pressure additive can form high-melting-point inorganic thin film to prevent from occurring under high loads clinkering, seizing, cut or scratch with the Steel Wire Surface reaction contacted, the particularly extreme-pressure additive of the borate family such as sodium metaborate, there is extreme pressure effective, and the advantages such as corrosion can not be caused to metal.
Below disclose the present invention with preferably embodiment, so it is not intended to limiting the invention, allly takes equivalent replacement or technical scheme that the scheme of equivalent transformation obtains, all drops in protection scope of the present invention.
