Abstract
The invention relates to a long-acting wire rope hemp core grease. The long-acting wire rope hemp core grease comprises 13-17wt% of palm wax, 16-19wt% of microcrystalline wax, 15-19wt% of naphthenic high-viscosity oil, 24-28wt% of paraffinic high-viscosity oil, 1.6-4.6wt% of zinc dialkyl dithiophosphate, 1.4-4.4wt% of nonyldiphenylamine, 4.5-8.5wt% of vinylacetic acid, 8.5-12.5wt% of polyisobutylene and 0.1-1wt% of calcium sulfonate. Compared with hemp core greases in the prior art, the long-acting wire rope hemp core grease has the advantages of high dropping point, no flowing in hot weather, fast online solidification after rope immersion, no loss, energy saving, no pollution to environment, large kinematic viscosity data, good adhesiveness, and realization of good fluidity and no flowing of a grease film in the motion and compressed processes. Prominently, the property of traditional hemp core greases (including imported hemp core greases) is changed to become weakly alkaline (the free base value is not greater than 0.15, NaOH%), so oxidation is effectively inhibited, generated free acids are neutralized, SH/T0325 oxidation stability test and SH/T0331 corrosion test are extremely well passed, the safe service life of a wire rope is effectively prolonged, and use environment is purified.
Description
Technical field
The present invention relates to a kind of synchronous with wireline, anti-oxidant, rust protection, being less than 65 DEG C of scope work can provide oil film, but do not run off, landing, the lubrication protection material of adhesivity, water resisting property, good reversibility, specifically a kind of long-acting wire-rope hempwicking grease.
Background technology
There is the wireline of hemp core in the course of processing, hemp core rope must being infiltrated through heating in the barrier cream of melt and dissolved state, after the specified time all floods, just can use.Otherwise during operation, inwall metallic surface does not reach protection and the lubrication of the good oil membrane of performance to wireline, can produce corrosion, shorten the life-span, do not accomplish safety in production, accidents happened.Even if found to lack protection, be also difficult to supplement.So must ensure that wireline inwall has enough qualified lubrication protection materials.Just can accomplish long-acting, safe operation, the main performance by fiber core grease has been come with infiltration quality, to extend its work-ing life.
