Description

The proposed lubricant is intended for use in the mining enterprises of various industries. thinking to prevent frostbite from sticking to and overburden; metal work surfaces

Sticking and freezing phenomena significantly affect the degree of use of mining equipment, for example, the performance of an OTBaxibHoro excavator is reduced by overburden by 1 O-.15% and rolling stock; by G5-20%,

; Known lubricant based on a mixture of kerosene and gas oil fractions with a thickener - perezin. A: The proposed material differs in that: in a mixture of kerosene-gas oil fraction of a glue, a cracking residue with ac content of at least 18 wt.%,

I The proposed lubricant for zapsht metal surface from when spanning and storing e-rims of spring rocks (conditional name Niogrin) is a mixture of korosino-gas-oil

ZOY fraction to the cracking unit. Below the drive, the approximate content of the components of the mixture, wt. including:

Kerosene fraction with boil off limits from 18О to 35О ° С40-9О

Gas oil fraction with a boil out of 350 to 350

SOQOC40-60

Cracking residue with an asphaltene content of at least 18% by weight. 0.5-20

The presence of these properties provides a high efficacy of a prophylactic substance.

In addition, Niogrin is not scarce and provides a relatively low cost of prevention (0.10-0.155 per 1 m3 of overburden). In large volumes: the substance can be obtained in coking, catalytic cracking plants and other plants in oil refineries.

The results of laboratory experiments (c; ..,. Rd, tsve 5 thousand experiments) showed that mbmr}} in: the lx film of the substance l-fiJorpHH, applied to a metallic noeepxiiOCTb reduces 8-10 times (up to 1 , 5 2.0 kg / cm compared with 16 kg / cm without prophylaxis) the strength of freezing of clay with critical humidity at a temperature of minus 30-40 ° C and a freezing time of 4 hours. This remedy reduces by 2-2.5 times the strength of sticking of moist clays {to 30-4O g / cm2 compared to 8O g / cm without prophylaxis). Results Chytnopro-. the test showed that / 84%, the dump cars unload the full .cL..IO, keeping the surface of the bottom and the walls of the dump car clean to metal. In the remaining 16% of dumpcars, the average volume of the remaining rock did not exceed 4% of the capacity, while in non-prevented dumpcars the volume of the remaining rock was from 10 to 6% of the capacity.

 Moreover, the tests showed the possibility of using a one-time coating with the substance Niogrin twice without reducing the effect of prophylaxis.
