Problems solved by technology

Aqueous solutions do have some disadvantages, however not in terms of algae eradication efficiency; for example, liquid algicide ingredients, including sodium hypochlorite, limit the shelf life of the algicide, which is typically six to eight months ; but if large quantities of the algicide ingredient are required, it is more expensive and less favorable to ship as an aqueous solution (generally, a gallon of aqueous solution contains about ten percent sodium hypochlorite)

Embodiment 1

[0049] Example 1: Preparation of ceramic meteorite-zinc oxide whisker-pink tourmaline mixture covered with nano-silver

[0050] step one:

[0051] Preparation of basic carrier-porous ceramic meteorite

[0052] 1. Material

[0053] Material: clay; nano alumina nano-Al2O3; nano zirconia nano-ZrO2; nano silicon oxide nano-SiO2 and nano silicon carbide nano-SiC

[0054] Control factors: purity, density, chemical composition, powder particle size, perforation, abrasion, absorbency, shape and quantity.

[0055] 2. Casting model

[0056] Pour in thick liquid to shape: sliding casting, pressing out, scraping edge cutting, scraper forming, injection forming.

[0057] Control factors: removal of organic substances (such as adhesives)

[0058] 3. Sintering

[0059] Fast firing, rapid reaction sintering, hot equalizing sintering.

[0060] Control factors: sintered capacitor, curve control and shrinkage rate.

[0061] 4. Processing

[0062] Nano silver coating and separation control.

[0063] ...

Embodiment 2

[0078] Example 2: Performance analysis of ceramic meteorite

[0079] The characteristics of ceramic meteorite samples are listed in Table 1 and Table 2 below.

[0081] Ceramic meteorite physical analysis results

Embodiment 3

[0082] Example 3: Sterilization effect of ceramic meteorite water filter

[0083] The ability of ceramic meteorites to inhibit microorganisms was demonstrated.

[0084] The antibacterial properties of ceramic meteorites are evaluated by ASTM E2149-011 (American Society for Testing and Materials, 2001), which is a quantitative antibacterial test method that is performed under dynamic contact conditions. Escherichia coli (ATCC 11229) is used as the test organism. The culture test experiment is to dilute with 0.3mM phosphate buffer (pH 7.2) to 105~106 colony forming units (CFU / ml) under nutrient culture medium. Used as a bacterial dilution solution when performing culture test experiments.

[0085] Each ceramic meteorite (1.08 g, nano-silver treatment and no nano-silver treatment, that is, the control group) is first sterilized with ultraviolet rays, and then put into a 10 ml test tube that has been filled with 3 ml of a bacterial dilution solution to make the substance to be tested ...

Abstract

This invention relates to a compound material for suppressing growing of alga including a carrier with porous basic substance and a nm metal mixture covering the carrier, in which, said mixture includes nm metal particles and a substance fixing the particles on the carrier. This invention further provides a method for suppressing the growing of alga.

Description

Technical field [0001] The present invention relates to a composite material for inhibiting the growth of algae, and also provides a method of using the composite material mentioned in the present invention for inhibiting the growth of algae. Background technique [0002] In industrial, fishery and general household applications, it is very dependent on the supply of water, so it is very important to control the quality of water under ideal expectations. [0003] Water containers used for transportation and preservation of drinking water for humans and animals, household water and agricultural chemical spraying water, and similar applications in these areas require fairly pure and pollution-free water. An important consideration is that the time for algae to grow in the small amount of water remaining in the water storage container far exceeds the imaginable time period, so the growth of algae in the water storage container is an extremely difficult problem. [0004] The growth o...
