Description
цах известной конструкции. Термообработку осуществл ют прокаткой объемно-спрессованного сло через гор чие вальцы, при этом температура поверхности вальцов соответствует температуре плавлени наиболее термопластичного волокна, т. е. равна 90°С.tsakh known designs. The heat treatment is carried out by rolling the body-pressed layer through the hot rollers, while the surface temperature of the rollers corresponds to the melting point of the most thermoplastic fiber, i.e. equal to 90 ° C.
В результате термообработки при температуре оплавлени наиболее термопластичного волокна прочность материала увеличилась в 2-2,3 раза по сравнению с известными способами, усадка материала устран етс полностью. Срок эксплуатации фильтровального материала вдвое выше по сравнению с материалом из иглопробивного полиэфирного эолокна.As a result of heat treatment at the melting temperature of the most thermoplastic fiber, the strength of the material increased by 2-2.3 times as compared with the known methods, the material shrinkage is completely eliminated. The life of the filter material is twice as high as the material of needle-punched polyester eoloc.
