Preparation method of nanometer photocatalyst film for degrading organic matter in waste water

The invention relates to a preparation method of a nanometer photocatalyst film for degrading organic matters in waste water, comprising the following steps: firstly, mixing a polymer PVDF or (VDF-HFP) and a plasticizing agent PC and DMC according to a mass ratio of 1:2-4:2-4; adding 10-20 percent of nanometer ZnO powder with a hexagonal system wurtzite structure or/and nanometer TiO2 powder witha pyramidal system anatase structure and evenly mixing; adding 2.5-5.5 times of (polymer mass, plasticizing agent mass and nanometer photocatalyst mass) acetone or acetonitrile; sufficiently mixing toobtain even and ropy suspending liquid; finally, casting the suspending liquid on slide glass to naturally flow and form; and standing, solidifying, drying, cooling anduncovering a film with thickness about 0.12-0.16mm from the slide glass. The nanometer photocatalyst film is even and consistent, has good mechanical property, can effectively degrade organic matters in the waste water and can be repeatedly ...

Process for producing Chinese medicine cell wall-broken micro powder

A cell wall breaking process for preparing superfine powder of Chinese-medicinal material is characterized by that the Chinese-medicinal material to be pulverized is put in a fully enclosed pulverizer where it is mechanically squeezed and impacted at -50-30 deg.C for solid emulsification. It can increase the biological utilization rate and cell wall breaking rate.

Substitutive treatment agent for metal surface phosphating and preparation method thereof

The invention discloses a substitutive treatment agent for metal surface phosphating and a preparation method thereof, and relates to the metal surface treatment technology. The substitutive treatment agent for phosphating consists of the following components of: gamma-APS, anhydrous alcohol, fluozirconate and de-ionized water, wherein the substitutive treatment agent for phosphating consisting of the components is a silane and nanoceramic composite film; the preparation method for the silane and nanoceramic composite film which consists of the components and is used for pre-treating the metal surface comprises the following steps of: rinsing with hot water; degreasing in advance; rinsing for the first time; rinsing for the second time; rinsing for the third time; performing phosphate-free conversion; rinsing a straight bar; rinsing for the fourth time; rinsing for the fifth time; and finishing the preparation. The substitutive treatment agent and the preparation method have the advantages ...
