一、管材配比试验管材配比试验的目的是:既要满足低压输水管道的防渗要求,又要尽可能降低水泥管的造价,从而找到一个管材最佳配比方案及制管工艺。整个试验中我们始终以管材的抗压强度、抗渗性能为控制管子质量的主要标准,寻找出管材的最佳配方。经过多次的反复试验,最后找出了水泥制管的最佳配方和理想的制管工艺。按照新配方新工艺生产的 First, the ratio of pipe material pipe test The purpose of the test is: it is necessary to meet the seepage requirements of low-pressure water pipelines, but also to reduce the cost of cement pipe as much as possible, so as to find the best ratio of a pipe and pipe manufacturing process. Throughout the experiment, we always take the pipe compressive strength, impermeability as the main standard to control the quality of the pipe, to find the best formula for the pipe. After repeated trial and error, finally found out the best formula of cement pipe and pipe manufacturing process. According to the new formula new technology production
