Cement pipe manufacturers explain the problems that can not be ignored in the production of cement drainage pipes
生产过程中不行忽视的一些问题 Some issues that cannot be ignored in the production of cement drainage pipes
The cement drainage pipe has the effect of adhering to soil and water in the development slope of the hillside. In the daily production of the cement drainage pipe, a seemingly very small problem often results in the poor quality and unqualified appearance of the produced drainage pipe And become a failed product. In actual production, seemingly small problems are often ignored by us, which leads to the emergence of the problem, so now I will introduce some small problems about cement drainage pipes that cannot be ignored in production as follows.
First, the problems of cement drainage pipes can not be ignored in the production process
1. The equipment technology for the production of cement drainage pipes and the selection and use of original materials are the key to the quality of cement drainage pipes. Therefore, in the process of producing cement drainage pipes, we should choose qualified cements that are relatively close to the ex-factory period because new The cement powder in the field is boring, the powder particles are soft and there is no contact with any moisture, and the cement with a long time easily absorbs the moisture in the air, which results in the phenomenon of agglomeration and agglomeration. The cement agglomerates that can be composed with one touch or one pinch can be used with an appropriate reduction in strength level.
2. Regarding the cement drain pipe produced, we must pay attention to adhere to the moisture of the cement to prevent the concrete from being exposed to sunlight after operation. The rapid evaporation of moisture will reduce the strength of the cement, and even the moisture on the surface of the cement drain pipe will evaporate. Quick and fissures appear, burying hidden dangers of engineering safety.
3. Regarding the produced cement drainage pipe, we must pay strict attention to the thermal insulation environment. After the concrete or mortar is stirred, if it is frozen, the cement cannot be hydrated, and because the water will swell after freezing, the concrete and mortar will suffer. When the surface and the inside of the cement drain pipe are gradually deepened and damaged, and the external temperature and internal temperature of the cement drain pipe show a large temperature difference, unqualified cracks often occur in the cement drain pipe. Therefore, it is necessary to be strict in the production operation of the cement drain pipe. Control the thermal environment temperature.
4. When making cement drainage pipes, the quality of the materials used must be good. When selecting cement, choose a cement type with excellent durability. Under special circumstances, you need to choose a special cement type, so that the quality of the cement drainage pipe can be guaranteed. Durability, other ingredients cannot be ignored in terms of quality
