Method for preparing molecular crystal cell material for sterilizing and killing algae


Inventor(s):     XIAOMIN JING, ET AL.

The invention discloses a method for preparing a molecular crystal cell material for sterilizing and killing algae, which comprises the following preparation processes: adding tetrasilver tetraoxide into ammonia hydroxide solution to form ammonia hydroxide solution of the tetrasilver tetraoxide; dissolving acrylic resin, epoxy resin, polyvinyl alcohol or polyurethane in water by heating to form gel; mixing the ammonia hydroxide solution of the tetrasilver tetraoxide and the gel to form tetrasilver tetraoxide gel solution; and spraying the tetrasilver tetraoxide gel solution on the surface of a silver-carried material, and drying the silver-carried material to form the molecular crystal cell material. The process is simple; because the tetrasilver tetraoxide in a sol-gel form is combined with the silver-carried material, the anti-bacterial capability of the prepared tetrasilver tetraoxide molecular crystal cell material is not influenced by environment; and the molecular crystal cell material can be used for sterilizing and algae killing of landscape pools and household view fish jars, also can be used for sterilizing and algae killing of underground water source and industrial circulating pool, and realizes the conversion from sterilizing and algae killing of a fluid bed to sterilizing and algae killing of a fixed bed in the application of a tetrasilver tetraoxide molecular crystal cell.

DESCRIPTION
[0001]

TECHNICAL FIELD
[0002]

The present invention relates to a method for preparing algae sterilization materials, particularly relates to a method for preparing biocide molecular crystal of battery materials.
[0003]

Background technique
[0004]

Silver and its compounds have antibacterial properties have been used in a variety of areas, such as fungicides, antimicrobial dressings, water purification equipment, ceramics, pharmaceuticals, etc.
[0005]

Currently, people bactericidal mechanism of silver and its compounds have been studied multi-faceted.
Its bactericidal properties and its valence and structure closely related to its antibacterial properties are as follows:
[0006]

Ag4O4> Ag3 +> Ag2 +> Ag +> Ag.
[0007]

Tetroxide four silver (Ag4O4) is composed of two trivalent silver, with silver valence polyvalent compound having two monovalent silver atoms and four oxygen atoms formed by dsp2 electrons.

It is a semiconductor, diamagnetic crystal active electronic, active electrons from single and triple bond between two electrons exchange were to form a battery can discharge kill bacteria.
[0008]

Tetroxide four silver is stable under normal circumstances, when faced with something like -NHx, -SH, -SS group, it will inspire Ag4O4 internal Ag3 + / Ag + electronic exchange transfer, a series of redox reactions and electron transition, the formation of chelates, complexes, a voltage of about 1.48 ~ 3V.

Killing effect to generate electricity so that bacteria, viruses -NHx, -SH, -SS group protein conformational change, loss of activity, no more copy, play sterilization, algae effect.
[0009]

Many studies show that research institutions: Ag4O4 to have selectively kill pathogens, but for normal human cells and the exterior environment showed no toxicity.
[0010]

U.S. Patent US6436420B disclose the contents Ag4O4 applied antimicrobial fabric.

[0017]

(4) The step (3) obtained in tetroxide four silver gelatin silver was sprayed on the surface of the material, drying 30-300 minutes at a temperature of 45-70 ? condition, which obtained with molecular sterilization crystal cell materials.
[0018]

The above step (4) in the silver material is pebbles, plastic, gravel, stone, slag or other water insoluble solids.
[0019]

The present invention is on the surface of the material will tetroxide four silver in the form of sol-gel intended for fixed landscape water sterilization, when the pool is in contact with the spores of algae tetroxide four silver, which produce electricity to kill, inhibit or kill the growth and reproduction of algae.
[0020]

The present invention over the prior art has the following advantages: simple process of the present invention, since tetroxide four silver in the form of sol-gel materials combined with silver, antibacterial prepared tetroxide molecular crystals of four silver battery materials from the environment influence, can be used for landscape pond and the family fish tank biocide, can also be used underground water sources and industrial recycling pool of sterilization, achieved by a fluid bed sterilization converted on a four-four silver oxide battery application for the fixed bed molecular crystals sterilization.
