Abstract

The invention relates to a material for filter pressing of superfine slurry and a manufacturing method of the material. The material is composed of a basic material layer with a pore diameter and a superfine pore filtering layer arranged at the upper part of the basic material layer, and the material is characterized in that an adhesive cement curing layer is used as the superfine pore filtering layer; superfine pore diameters are distributed on the adhesive cement curing layer; and the adhesive cement curing layer is formed by mixing a resin material, an inert grain, a volatilizable solvent and a curing agent, and drying and curing. The manufacturing method disclosed by the invention is simple in process and low in cost; and the material for the filter pressing of the superfine slurry has the advantages of guaranteeing the superfine pore diameters and reducing filter pressing resistance.

Description

technical field [0001] The invention relates to the technical field of filter press materials, in particular to a material for ultrafine slurry filter press and a manufacturing method thereof. Background technique [0002] In the production of fine ceramics, it is often necessary to wash the powder or carry out press-filter forming, and ultra-fine pore-diameter filter-press materials are used at this time. The pore size of the ultra-fine pore filter press material must not only allow liquid to flow through, but also ensure that the slurry particles cannot pass through. In addition to ensuring the pore size of the ultra-fine pore filter press material, the filter press speed also seriously affects the production efficiency. In the prior art, in order to increase the filtration speed and reduce the filtration resistance, the commonly adopted method is to make the filter membrane or filter plate thinner. [0003] The prior art has the following problems in the production of ul...
