Titanic oxide nano pipe/high-efficiency glass fiber filter in situ synthesis supporting method

Abstract

The invention discloses a support method of the in situ synthesis of titanic oxide nanotube / highly efficient glass fiber filter paper, which is characterized in that the method comprises the following steps that: (1) TiO2 powder is added into an NaOH solution and the mixed solution is transferred to a reaction kettle; (2) precipitate is obtained after hydrothermal reaction at a constant temperature of 110DEG C- 160DEG C for 6h-72h; (3) the precipitate obtained in step (2) is mixed with ethanol to form stable suspension after ultrasonic dispersion treatment for 15min, repeatedly filtered and washed by HEPA filter paper and deionized water until filter liquor is neutral; (4) the HEPA filter paper obtained from the step (3) is dried at 60DEG C. The method realizes the automatic cleaning andbactericidal function of the glass fiber filter paper, prolongs the service life of the filter paper, has simple technique and low requirements for materials and is suitable for industrial production.

Description

technical field The invention relates to a method for preparing filter paper for air filtration and purification, in particular to an in-situ synthesis and immobilization method of a one-dimensional nanotube structure photocatalytic material on a high-efficiency air filtration substrate. Background technique With the continuous development of social industrial production, the current environmental quality is deteriorating, and air pollution is becoming more and more serious. Due to the continuous increase of airborne pollutants such as harmful dust, smoke and other pollutants, it is very easy to cause people to suffer from respiratory tract infections, allergies, and asthma. Outbreaks and other diseases with symptoms directly related to air pollution, so people pay more attention to improving ambient air conditions. HEPA—glass fiber air filter paper is a high-efficiency filter material, mainly used as air and liquid purification filter paper. For example, it can remove har...
