纳凯夫纤维(NACF/NKAF)
纳凯夫(NACK/NKAF)纤维是一种非石棉复合纤维,为我公司首创。它具有作为摩擦密封材料增强纤维最为重要的特性:
1.纤维比表面积大,吸附性能好;
2.纤维束间附着阻尼剂,纤维的内聚力小,分散性能好;
3.纤维表面经过化学处理,与配方中的其他组分连接性能优良;
4.具有生物降解性,对人和环境安全。
The asbestos free compound fibre(NACF/NKAF)
The NACF/NKAF fibre is asbestos free compound fibre. It was developed first by our experts. It has these main properties of used for friction and sealing materials. The fibre's ratio surface area is big, so its absorptive capacity is very good. The fibre cling to damping agent, fibre's cohesion is small, so its scattering property is excellent. The fibre's surface goes through chemical treatment, so its binding capacity with other elements is good. It can be biodegradable, so it is safe and harmless to environment.
