Generally, the price of refined acid pickling and passivation textured sand is required. The bottom edge is a small foundation cushion, and the bottom is higher from bottom to large to small. Do not jump, or the softener is easy to infiltrate and endanger the outflow water body. Therefore, improving the filtration rate and the water production rate of the total area of the enterprise is an important way to improve the wastewater interception capacity, reduce the project cost and reduce the use space. The refining process of textured sand is close to perfection at this stage, and textured sand is used to solve high energy consuming chemicals. Its basic working principle is to filter waste out of stone. The carcinogens and pollutants in the water are filtered out, and refined quartz sand is mainly used in suspended solids.

If the test material is not sintered, it shall be replaced with a new test material, and 50 degrees shall be raised one by one according to the sintering condition until the test material is sintered. Test materials with sintering point higher than 1350 ℃ shall be tested in high temperature electric furnace with temperature higher than 1350 ℃. During the test, put the test material on the heat-resistant porcelain boat or tablet computer, and carry out the test according to the above requirements. The actual screening effect of white quartz sand filter varies with the actual filtering effect. Quartz sand filter material is now the filter material for economic development. Most sewage treatment stations are inseparable from quartz sand filtration materials and quartz sand filtration devices. At present, there are three kinds of quartz sand filtering devices, single filter, double filter and multi-media filter.

The scratch hardness of quartz sand filter material is also called Mohs hardness tester. Mainly used for hardness and softness of different minerals. The method is to first select a component with one hard end and one soft end, then cross the tested material along the component, and determine the hardness and flexibility of the tested material according to the length of the scratch. In terms of quality, hard objects have long scratches and soft objects have short scratches. Hardness of quartz sand filter material. Mainly used in metal materials and quartz sand materials. The method is to put the tension of the specification into the tested material at the load effect, and compare the hardness and softness of the tested material with the partial plastic deformation of the material surface.

Activity of surface treated heavy calcium: surface treated heavy calcium is also called active heavy calcium. In order to better improve its fusion with the raw materials of the base material and enhance its dispersivity, it is necessary to solve its activity. For heavy calcium manufacturing enterprises, surface treatment of calcium carbonate is the main way of commodity production and processing, which can enhance the added value and obtain faster economic benefits. However, for the active calcium carbonate and the following customers, the active calcium carbonate should be used, followed by heavy calcium, which is usually solved by physical covering or organic chemical mechanical equipment to modify materials. Its working principle and the whole process are different from the anti condensation solution of carbonization in the production process of light calcium.
