目前用可塑法制浇注砖的技术操作不能保证制成高质量的制品,同时,由于必须经过乾燥,在生产中造成了很高的废品率。经验证明,如用半乾成型法代替可塑法,特别是用多熟料的压制方法代替可塑成型法时,生产中废品率显著下降,而质量确提高了。舍尔宾工厂掌握了用熟料含量80％、水份10—12％的多熟料以可塑性成型法生产制品的方法。 At present, the technical operation of plastic molding pouring brick can not guarantee the manufacture of high-quality products, and at the same time, it has a high rejection rate in production due to the necessity of drying. Experience has shown that if the semi-dry molding method instead of plastic molding method, in particular, the use of multi-clinker pressing method instead of plastic molding method, the production of significantly reduced the rejection rate, and the quality is indeed improved. Sherbin factory has mastered the method of producing products by plastic molding with multiple clinker with clinker content of 80% and water content of 10-12%.
