Information

Cellulose filtration aid products are substances that can improve the filtration efficiency of filtrate. Therefore, this substance can not only prevent the accumulation of filter residues from being too dense and make the filtration proceed smoothly, but also have the following functions.
 Cellulose filtration aid products
1. Retaining effect
       In depth filtration, the separation process only occurs in the "inside" of the medium, and the relatively small impurity particles that partially penetrate the surface of the filter cake are trapped by the tortuous microporous channels inside the cellulose filtration aid products and the finer pores inside the filter cake. Retention, such particles are often smaller than the pores of the filter aid. When the particles hit the walls of the channel, this may break out of the flow, but whether it can achieve this depends on the inertial force and resistance to which the particles are subjected The balance of this kind of interception and sieving is similar in nature, and both belong to mechanical action. The ability to filter out solid particles is essentially only related to the relative size and shape of the solid particles and pores.
 
2. Screening function
       This is a surface filtration effect. When the fluid flows through cellulose filtration aid products, the pores of the filter aid are smaller than the particle size of the impurity particles, so that the impurity particles cannot pass through and are trapped. This effect is called sieving effect. . In fact, the surface of the filter cake can be regarded as a sieve surface with an equivalent average pore size. When the diameter of the solid particles is not less than (or slightly smaller) than the pore diameter of the filter aid, the solid particles will be "sieved" from the suspension. Divided" out, playing the role of surface filtration.
 
3. Adsorption
       Different from the above two filtration mechanisms, this effect can actually be regarded as electrokinetic attraction, which mainly depends on the surface properties of solid particles and cellulose filtration aid products themselves. When those particles with small pores inside the filter aid collide with the inner surface of the porous filter aid, they are attracted by opposite charges. Another is the mutual attraction between the particles to form chains and stick to the cellulose filtration aid products. These are all adsorptions.

The above is a brief introduction to the three main functions of cellulose filtration aid products, and I hope it will be helpful for your further understanding.
