不少人认为,油毡表面撒布料的作用,只是为了防止油毡在运输、贮存、堆放期间表面粘结。基于这一认识,我国绝大部分油毡厂采用滑石粉作撒布料。因为滑石粉不亲油,摩擦系数小,符合防粘要求。同时这种撒布料已经标准化,这就更加同化了人们对油毡撒布料作用的观点。我们通过实践认为,油毡撒布料的作用,除防止油毡表面粘结外,更重要的是,它还可改善油毡的质量。选择时,还要考虑到油毡的使用性能和撒布料本身的来源和经济性。采用滑石粉作撒布料,造价高,不经济。油毡表面有一层滑石粉,不但没有改善油毡的
Many people believe that the effect of spreading fabrics on the surface of linoleum is only to prevent the linoleum surface from sticking during transportation, storage and stacking. Based on this understanding, most of the linoleum plants in China use talcum powder for spreading fabrics. Because talcum powder is not lipophilic, the friction coefficient is small and it meets the requirements of anti-sticking. At the same time, this kind of spreading cloth has been standardized, which has even more assimilated people’s views on the effect of spreading felt on fabrics. Through practice, we believe that the role of linoleum spreading fabrics, in addition to preventing the linoleum surface adhesion, more importantly, it can also improve the quality of linoleum. When choosing, also consider the performance of the linoleum and the source and economics of spreading the fabric itself. The use of talcum powder for spreading fabrics is costly and uneconomical. A layer of talcum powder on the surface of the linoleum not only did not improve the felt
