Dry mortar production line of raw materials control management are what aspects

Dry mortar production line is a modern dry mortar production equipment, through the cement, sand and gravel, powder and additives according to the appropriate ratio of automatic ingredients, mixed into the pouring material. The production of dry mortar equipment makes the quality of dry mortar more stable, and has high production efficiency, reducing dust, noise and other environmental pollution is more conducive to civilized construction and improve the quality of the project, thus triggering the climax of the development of dry mortar in China. Improve the construction quality of the traditional dry lake mortar problems. So what are the aspects of control management of the original materials used in the production of dry mortar equipment.

The raw materials used in the production of dry mortar equipment will not cause harmful effects on human beings, organisms and the environment, and should be in line with the provisions of China and environmental protection and other relevant standards, the quality of raw materials should meet the requirements of the production technology of dry mortar equipment, materials into the plant should be stored according to species classification, and clear identification, and should adhere to the "first test, then use The principle of "test first, use later" should be adhered to. Enterprises should select qualified suppliers according to quality control requirements, establish and maintain files of qualified suppliers and regularly review qualified suppliers; purchasing contracts should be reviewed by purchasing, production and technical parties to ensure that the raw materials purchased meet the requirements for use; purchasing departments should strictly follow the raw material quality standards to organise balanced purchasing.

The cement used in dry mortar equipment is the main cementitious material in the mortar and plays a decisive role in the quality of the mortar. The focus of cement quality control is stability control. Specifically, the following aspects should be controlled: the cement used in dry-mix mortar is silicate cement and should conform to the current Chinese standard GB175 "General Silicate Cement". When other cements are used, they shall comply with the provisions of the corresponding standards. The strength grade of cement should be selected according to the requirements of the mortar type and strength grade; P.C32.5 cement should be used for mortars of strength grade M13 and below; P.O42.5 cement should be used for mortars of strength grade M15 and above. It is advisable to use bulk cement, as far as possible, the same manufacturer, the same brand of cement, often changing cement varieties and grades, is not conducive to technical personnel to master and use, is not conducive to the quality of dry mortar stability. When the cement is put into the storage bin, the bin number should be checked carefully to ensure that the bin position is accurate. The incoming cement should be retested according to the provisions of our current standards, and only after passing the retest can it be used, including strength, stability and other necessary performance indicators.
