High-viscosity liquid is the viscosity is much greater than the flow state of water, their viscosity is very high, the viscosity of the polymer solution of synthetic fibers can reach tens of Poe to hundreds of Poe. Molecular weight is the main factor affecting the viscosity of the substance, with the increase in molecular weight and the greater the viscosity, while the temperature increases, viscosity is usually reduced, high viscosity liquids usually present a turbid plastisol characteristics. In the process of filtration without stopping or interrupting the polymer high viscosity liquid filtration, its main purpose is to remove the granular impurities, these particles are a variety of forms of gum particles and semi-gum particles, non-uniform impurities, solid particles from raw materials, the particle size of 0.1µm ~ 100µm, particles in the media first form a filter cake, through the filter hole or deposited in the pore channel, very easy to block the filter media pores.

Viscous liquid filter bag features.

The material of the filter bag determines the flow rate and the ability to retain impurities in the polymer, commonly used filter bag materials are: stainless steel filter bag can be very high differential pressure to intercept deformable particles, colloids, PP, PE, NMO deep filtration, porosity up to 90%, remove the polymer gel, added coagulants and catalysts, impurities contained in the polymer.

Notes on viscous liquid filter bags.

1, viscous liquid filter bag flow: If it is resin can add an extra layer of hot oil pipeline, increase the temperature to increase the flow rate evacuation, keep a constant temperature is not affected by weather changes in the pipeline temperature changes, so as to achieve high flow production.

2, viscous liquid filter bag viscosity: in the process of filtration, we usually ask to try to speed up the production speed, improve filtration efficiency, when the viscosity in too high, the pressure, filtration area remains unchanged, the speed will become the original slower, so in the case of high viscosity add diversion float, increase the filtration area, improve the fluid pressure, so as to improve the filtration speed.

3, viscous liquid filter bag PH value: first of all, according to the PH value of the ink to select the corresponding ink filter bag, if the PH presents strong acid or strong alkali, filter bag selection is not appropriate, will corrode the filter bag, thus forming a burst bag, affecting the filtration effect, or even scrap a batch of materials.

4, viscous liquid filter bag impurity content: If the ink in the filtration of impurities is very high, then the ordinary single ink filter bag filtration efficiency will be reduced, the filter bag will be frequently replaced, for labor costs will increase, at this time, you need to match the multi-bag filter to increase the filtration area.

5, viscous liquid filter bag filtration, due to high viscosity, the chances of bag breakage will increase, at this time, you need to pay more attention to the pressure gauge display parameters, it is recommended that customers reach a kilogram of differential pressure when the replacement of filter bags.

Shanghai Jiuching tells you that viscous liquid filter bags can be used in: automobile manufacturing, chemicals, food and beverage, petroleum products and ink, etc. For details, please pay attention to the official website.
