Material: 100% cotton
Its thickness, hardness, length and width can be customized according to customer requirements.
Cotton canvas cleaning block: It is an ideal product in the high-screen cleaning process of large-scale flour manufacturing. The cleaning block and push block produced by our company are made of pure natural high quality cotton yarn and made of heavy looms. The product has high density and high hardness, is non-toxic and tasteless, and is environmentally friendly. In the past few years, it has been favored by many domestic flour enterprises and exported to Italy, the United States and other countries.
The product has the characteristics of wear resistance, heat resistance, no peeling and no damage to the screen. It has exceeded the same products at home and abroad in terms of thickness, hardness and service life. Now it has been used in the high square screen of many domestic flour enterprises. in.
Screen cleaning accessories:
The cleaning block and the push block are required to have good toughness and wear resistance due to working conditions, so they are produced from polyurethane raw materials. Polyurethane can be divided into polyester type and polyether type according to its molecular structure. Polyether type has good hydrolytic stability, high resilience and low temperature flexibility, and high strength. It is suitable for high humidity and continuous high strength and high resilience. The high-grade sieve is used; the polyester type has good tensile properties, flexural properties and wear resistance, but its fatal weakness is easily broken by water molecules. Polyester polyurethane products should not be used because of the high ambient humidity in the high-level flat screen under the powder between the two skin mills. Because the price difference between the two is large, most of the manufacturers in the industry consider the price. Therefore, the polyester polyurethane is used to produce the cleaning block and the pushing block. Therefore, the polyester polyurethane product must exist under the condition of high humidity. The aging fracture problem occurs repeatedly after use. Our company has recommended to recommend the use of FDA-compliant polyether polyurethane cleaning blocks and push blocks.
Pure cotton grade This product is developed by our company according to the advantages of the Swiss Buhler and Italian company's products. The product has the advantages of heat resistance, wear resistance, no opening, no damage to the sieve screen, good elasticity, etc. Its thickness, width, length, hardness and service life have surpassed similar foreign products. Our company is the main production base of domestic canvas cleaning blocks, and is now widely used in many well-known grain machine factories and large flour manufacturers. Square sieve
1) Cross-shaped push block: optimized shape, soft structure, suitable for spacer sifters.
2) Diamond-shaped pusher block can maintain shape and elasticity after continuous use for a long time. This specification is suitable for small-interval sifters. This pusher block is used in standard size sifters to minimize frame wear. Because this is a large diamond shape (compared to the three-dimensional diamond shape), the center volume is reduced and the weight is reduced, which is the highest cleaning effect of the product throughout the surface movement.
3) Square push block for standard size sifters to minimize frame wear.
4) Plum-shaped push block, increase the shape of the push block, more suitable for increasing the use of the sieve.
5) The triangular pushing block, the pushing block increases the thickness, and the middle hole can reduce the material pressure, increase the production efficiency and prolong the service life.
