ZhongBo Industry and Mining Machinery Co.,Ltd mainly engaged in the r&d, manufacture and sales. Leading products are common, heat-resistant (high temperature), acid and alkali resistant, oil resistant, cold resistant, wear resistant, flame retardant and different properties of cotton canvas (CC), nylon (NN) conveyor belt, polyester (EP) flat and large Angle gear sideband, decorative pattern, such as conveyor belt. The raised edge conveyor belt for everyone to introduce improvements with body material and specific measures.
Conveyor belt in real conditions, the available plate vulcanizing press vulcanization NN and EP fabric core conveyor belt. As long as narrow-band core, don't let mat iron edge close to the strip belt, wide space, set aside with core along the lines can be avoided. The relation between them is: > > semi-finished bandwidth, the distance between iron core width. A suitable cloth belt core narrow factors should not only consider the core layer of lateral delay quantity wide, but also to estimate the vulcanizing shrinkage in width direction, after the final guarantee the standard width of the finished product is reasonable. Specific prevention measures are as follows:
1, fabric skeleton performance is decided to take the root of performance. The belt with NN and EP fabric weft to take-up excessive elongation is the root cause of the arrange grain. Reducing weft elongation is to improve performance is also an effective way to reduce costs.
2, when the strip forming shrinkage narrow-band core can avoid generated along the grain.
3, lead to arrange grain generated related factors cannot be ignored.
4, fabric of thermal shrinkage is not the cause of appears along the grain, it's just a general properties of chemical fiber fabrics.
Guard conveyor belt in order to satisfy the large overloading, bearing and traction big work load requirement, the used material is optimized to improve.
Jingcheng rubber conveyor belt guard and specific measures for improvement are:
1, selection of baseband body skeleton material tensile strength of polyester tire cord tensile body, its tensile strength is 200 kg / 2.5 cm, is 3 times of ordinary cotton canvas;
2, in order to improve the baseband and waveform guard of the abrasion resistance and fracture resistance, in the colloid mixed right amount of polyester short fiber, according to the performance requirements of the colloidal mortar can be used in 10% ~ 20% matching. With colloid interface bonding strength in order to improve the polyester staple fiber, polyester short fiber must be used again after improve invasive pretreatment in rubber mixing. Mixed with staple for waveform guard after resistance to tear strength can reach 80 kN · m ~ ~, the tensile strength can reach 20 ~ 26 mpa, to improve the effect of colloidal properties is ideal.
