According to the investigation and analysis, 95% of the reasons for the removal of blankets are that the pores are blocked by dirt, and only 5% are due to wear and other reasons The purpose of washing is to wash away the dirt adhered to the surface of the blanket and accumulated inside the blanket, restore the elasticity and loose thickness of the blanket, so as to maintain the good water filtration, moisture content and air permeability of the blanket
For the organizational structure of the bottom net layer (base net) of BOM paper-making felt, the warp (MD direction) uses ply or twisted monofilament, while the weft (CD direction) is mostly monofilament. Because the bottom net woven by it has smooth surface and large porosity, fine fibers and dirt are not easy to adhere to the bottom net layer. Dirt is mainly deposited in the surface fiber tissue in contact with the paper sheet, especially when more fine and short fibers are used on the surface Therefore, the flocking ratio (the ratio of fiber content to base fabric content) is an important parameter to determine whether the blanket is easy to jam. The smaller the ratio, the less likely it is to jam
The washing of blankets is inseparable from water. In order to achieve the ideal washing effect, there are certain requirements for water quality Whether surface water or groundwater is used, it can only be used after purification and filtration of water supply engineering The water purified by the water supply project can basically meet the water quality requirements for blanket washing only after it is filtered through a 100 mesh sieve
Hot water is beneficial to the washing of paper-making blankets.
The water temperature increases from 10 ℃ to 30 ℃, and its viscosity decreases by 64% Therefore, it is suggested that the temperature of high-pressure water should be higher than 40 ℃.
