Nylon material and application thereof

Abstract

The invention discloses a nylon material. The raw materials of the nylon material comprise the following components: 1000 parts of caprolactam, 30-40 parts of modified polyethylene micro wax powder, 1.5-2 parts of red lead, 1.5-2 parts of sodium hydroxide and 3.5-4 parts of a curing agent TDI. The invention discloses application of the nylon material in a sliding block. The invention relates to aslide block production process, which comprises: S1, placing caprolactam in a material melting furnace, performing heating to a temperature of 70-100DEG C, and starting discharging; and S2, performingweighing according to the feeding amount of a mold. Compared with a traditional MC nylon product, the product provided by the invention has the characteristics of low friction coefficient, good wearresistance and the like, the defect that the friction coefficient is high when nylon and steel rub each other for a long time is overcome, the friction system is 1 / 3 that of traditional nylon, the friction coefficient is stable, the friction temperature rise is low, the product is a good substitute for a crane jib sliding block, the friction coefficient and the friction resistance of a jib duringlow-speed sliding can be effectively reduced, the jib can stretch out and draw back more smoothly, and the creeping phenomenon is reduced or eliminated.

Description

technical field [0001] The invention relates to the technical field of sliders, in particular to a nylon material and its application. Background technique [0002] The slider is a mold component that can slide perpendicular to the mold opening and closing direction or at a certain angle to the mold opening and closing direction during the mold opening action. When the product structure makes the mold unable to demould normally without using the slider, the slider must be used. The material itself has appropriate hardness and wear resistance, which is enough to withstand the friction of movement. The hardness of the cavity part or core part on the slider should be at the same level as other parts of the cavity core. [0003] The slider is widely used in the booms of the cranes in transportation, loading and unloading, road construction and other places or temporary hoisting operations to reduce the frictional resistance when the boom stretches. It has soft material, good t...

AI Technical Summary

Problems solved by technology

[0004] The fit gap between the nylon slider and the boom is 1-2mm. If the dimensional tolerance and shape tolerance are out of tolerance during the boom manufacturing process, the gap after the boom assembly will be too large or too small

If the gap is too large, the boom will vibrate during the crane operation. If the boom is stretched out and the deflection is too large, it will cause poor stability during hoisting and pose a safety hazard.

If the assembly clearance is adjusted too small, it will not only cause the frictional resistance to increase sharply when the boom stretches to the position where the shape and position tolerance is out of tolerance, accelerate the wear of the nylon slider, shorten the service life of the nylon slider, and even cause the movement of the boom to be blocked in severe cases , and even cause the telescopic cylinder to bend and deform, what's more

[0005] cause serious safety accidents
