尼龙衬板性能
Properties of nylon liner
作为工程塑料的尼龙衬板分子量一般为1.5-3万尼龙具有很高的机械强度，软化点高，耐热，磨擦系数低，耐磨损，自润滑性，吸震性和消音性，耐油，耐弱酸，耐碱和一般溶剂，电绝缘性好，有自熄性，无毒，无臭，耐候性好，染色性差。尼龙衬板缺点是吸水性大，影响尺寸稳定性和电性能，纤维增强可降低树脂吸水率，使其能在高温、高湿下工作。尼龙衬板与玻璃纤维亲合性十分良好。
The molecular weight of nylon lining as engineering plastics is generally 1.5-3 000 nylon with high mechanical strength, high softening point, low heat resistance, low friction coefficient, abrasion resistance, self lubrication, shock absorption and silencer, oil resistance, weak acid resistance, alkali resistance and general solvent, good electrical insulation, self extinguishing, non-toxic, odorless, weatherability, The dyeability is poor. The disadvantage of nylon liner is large water absorption, which affects the dimensional stability and electrical properties. Fiber reinforcement can reduce the water absorption rate of the resin and enable it to work at high temperature and high humidity. Nylon liners and glass fibers have good affinity.
延长使用寿命措施
Measures for prolonging service life
(1)衬板与研磨体可选用性能优良的相同抗磨材质配副;
(1) the lining plate and the abrasive body can be selected with the same antifriction material with excellent performance.
(2)严格控制入磨物料综合水分,加强磨机通风及简体粉磨温度,也可引入助磨剂,以减轻物料对衬板的磨损;
(2) strictly control the comprehensive moisture content of the grinding materials, strengthen the ventilation and the grinding temperature of the grinding mill, and also introduce the grinding aids to reduce the wear of the materials against the lining boards.
(3)改进和优化衬板结构。
(3) improve and optimize the lining structure.
