METHOD FOR PREPARING FILTERING MATERIAL Russian patent published in 2006 - IPC C08G8/22 B01D39/16 B01J20/26

Abstract RU 2286354 C1

FIELD: filtering materials.

SUBSTANCE: invention relates to technology and a method for preparing filtering materials based on polymers of space-globular structure and can be used in systems for water filtration. Invention describes a method for preparing a filtering material involving polycondensation of aqueous-organic resorcinol and furfurol solutions in the presence of acid at heating up to achievement of dynamic viscosity value of solution 30-50 mP, molding the forming resin by cooling at the rate providing preparing the material with average pores diameter in the range 0.3-5 mcm, and keeping for the complete hardening the polymer. Invention provides the development of preparing safety by sanitary norms and laws of the filtering material being without additional treatment of filters and sewage from formaldehyde.

EFFECT: improved preparing method.
