生产优质的石棉水泥制品,一般认为要用长纤维石棉,但实践证明,用短纤维石棉,只要采取一些相应的措施,也可以制出质量优良的产品.现将各厂在这方面所取得的一些经验简要介绍如下: 1.除去石棉中杂质.由于短纤维石棉中夹有大量粉尘、砂石等杂质,会降低产品的强度,因此用短纤维石棉生产石棉水泥制品时,要先将石棉进行精选,除去其中夹杂物.另外,短纤维石棉中含有不少石棉束,根据松江
The production of high-quality asbestos cement products generally considers the use of long-fiber asbestos, but practice has shown that with short-fiber asbestos, as long as some corresponding measures are taken, excellent quality products can also be produced. Now the plants have achieved in this area. Some experiences are briefly introduced as follows: 1. Remove impurities from asbestos. Since short fiber asbestos contains a large amount of dust, sand, and other impurities, it will reduce the strength of the product. Therefore, when asbestos cement products are produced from short fiber asbestos, the asbestos must first be processed. Selection, removal of inclusions. In addition, short fiber asbestos contains a lot of asbestos bundles, according to Songjiang
