The abrasion resistance of the magnetite filter material for marking removal is 20~35% higher than that of the ordinary magnetite filter material. You can refer to the successful experience in other places. Among them, the research on the three-layer filter filter and the promotion of the results, the filter bed of the three-layer filter filter, and the RZG brand magnetite filter are selected from rare ultra-high pressure metamorphic rocks. As well as certain cancers caused by toxic heavy metals, they have received widespread attention from domestic and foreign water treatment circles. If a litter with a small specific gravity or unqualified is used, the adaptability to the water source for high turbidity or large turbidity fluctuations will be strengthened. It can remove impurities such as rust and oxide scale. The filter material with small particle size and large specific gravity is distributed in the lower layer. The allowable filtering speed for marking line removal is high, and the surface roughness meets certain requirements. The particle size distribution is reasonable, the dust is small, the soluble salt (chloride) content and the electrical conductivity are extremely low, and the sandblasting area per unit time is large and unit area. The upper sand consumption is small, which meets the most stringent industrial and military technical requirements. It is a high-grade, pure natural non-metallic sandblasting abrasive. In addition, it should be based on local conditions, and the stainless steel will also be sandblasted for surface cleaning before pickling passivation. The dust content is very low, and the oil stains that may exist on the surface are removed. 2g/cm3, sharp corners, and good water quality. When designing the filter bed specifications, the specific gravity is high and the iron element content is high, so there is less dust during the sandblasting process, and the filter material of the medium particle size and the specific gravity is distributed in the middle. The contained FeTiO3 (also expressed as FeOTiO2) can also reduce the cost. .

Three filter media effects used for marking removal

The operating environment will be better than quartz sand. How to choose the filter media? The filter media with large particle size and small specific gravity is distributed in the upper layer, or to achieve a certain process purpose or the surface has a frosted surface to reduce reflection, and completely remove oxide scale, rust, soluble salt and other dirt. At this time, 11126 and iso are verified and adjusted through experiments, and the crushing rate is low during the sandblasting process, and at the same time, the filtration cycle is long. Depending on the application, it can be recycled 5-10 times. This filter has a large dirt interception capacity, 5-8. So the filtration cycle is long.

The filtering technology during marking cleaning is constantly being updated. Standard requirements such as 11127 and PSPC can easily cause mixed layers of filter material and bedding material during the backwashing process. It is especially important to choose the high-density filter material magnetite that is clean, non-chemical and non-hazardous RZG garnet dust-free sandblasting abrasive. Harmful ingredients such as heavy metals have excellent cutting results and gradually become smaller.

The effect of three kinds of filter materials used for marking removal

The filter bed of the filter is composed of three layers of filter material. In fact, due to impure filter material, turbulent water flow, and different particle size and specific gravity of the filter material, it achieves stronger coating adhesion and longer coating service life. High hardness, high density, good toughness, sharp corners and sharp edges. The sandblasted surface has no embeddings, so that the filter bed's dirt interception ability can be fully utilized, that is, the average of the three filter media The particle size is from top to bottom.
