在保证产品强度不低于技术条件规定的指标下,适当的调整单位产品水泥的用量,保持石棉纤维固有的含量,降低产品厚度,相应的提高石棉与水泥的配合比,是提高产品极限强度,减少单位产品重量,降低成本、节省钢材、木材和降低工程造价的有效方法.兹将我厂在工艺条件相同的情况下,进行的不同产品厚度和石棉配合比的系统试验介绍如下: 一、不同厚度单位产品原料定额的计算: 设:v为单位产品的体积; p为单位产品的总重量(包括石棉、水泥和水份); y为单位产品石棉与水泥的总重量; 瓦坯经过压瓦机后的含水量取24.5%.
To ensure that the product strength is not lower than the specification of the technical conditions, properly adjust the amount of cement per unit product, maintain the inherent content of asbestos fibers, reduce the thickness of the product, and accordingly increase the mix ratio of asbestos and cement, which is to increase the ultimate strength of the product. The effective method of reducing unit product weight, reducing cost, saving steel, wood and reducing project cost. The system test of different product thickness and asbestos mix ratio conducted under the same process conditions in our factory is described as follows: I. Different Thickness per unit of product raw material calculation: Let: v is the volume of the product; p is the total weight of the product (including asbestos, cement and moisture); y is the total weight of the product asbestos and cement; The moisture content after the machine takes 24.5%.
