Introduction to the role of cellulose filter aid
Cellulose filter aid uses natural raw materials as raw materials and is refined through grinding technology and fractional distillation (screening, screening), and is an environmentally friendly product that can be fully degraded. Compared with traditional filter aids, it has the main advantages. 2. Low density of wet cake 3. Higher filtration flow rate and longer filtration cycle; 4. It is not easy to precipitate in the pipeline; damage.
In the filtration operation, in order to reduce the filtration resistance, increase the filtration rate or obtain a highly clarified filtrate, an auxiliary powdery substance is added, called cellulose filter aid.
Basic requirements of cellulose filter aid:
1. Rigid particles that can form a porous cake layer, so that the filter cake has good permeability and low fluid resistance.
2. Has chemical stability
3. Incompressible within the operating pressure range
Commonly used filter aids are diatomite, perlite, cellulose, asbestos, graphite powder, sawdust, magnesium oxide, gypsum, activated carbon, acid clay, etc. In the paper industry, cellulose filter aid is a chemical added to improve the drainage and dewatering speed of wet paper from the papermaking wire.
