Description

1284510 IX. Description of the Invention: [Technical Field] The present invention relates to a composite material for inhibiting the growth of algae, and also provides a method for using the composite material of the present invention for inhibiting the growth of algae. [Prior Art] In industrial, fishery, and general household applications, it is highly dependent on the supply of water, so controlling the quality of water is very important under ideal expectations. • Water containers for transporting and storing drinking water for humans and animals, household water and agricultural chemicals, such as these applications, require relatively pure and non-polluting water. An important consideration is that the time it takes for algae to grow in a small amount of water remaining in a water storage container far exceeds the imaginable time period, so growing algae in a water storage container is a very difficult problem. Algae growth can cause many problems, such as blocking the filter of the water filtration device, or consuming the dissolved oxygen in the water, causing fish and shellfish to suffocate and die. Algae come in many forms, including microalgae, unicellular algae, filamentous algae like hair, algae that grow into flaky, large algae that look like plants; even some algae can survive in outer coverings like #皮Internal, or some coral, anemones and other calcified shells of sessile invertebrates called zooxanthellae. Some algae that look muddy are usually not algae, but rather a community of primitive photosynthesis organisms, such as blue-green algae. There are also some small green dots that are difficult to remove. These green dots sometimes grow on the aquarium's panels. These green dots are not algae, but are diatoms or radialarians. The various animal groups (microscopic, monocytic and hard-shelled animals) are formed by combining algae. It is inevitable that algae grow in the aquarium, and the algae will consume the nutrients accumulated in the water', so it is harmful to fish. 6 1284510 ^Algae growth can be made into three or more, most categories are based on the lowest based priming considerations - that is, according to long-term cost, safety, and easy to use all sides considerations _ _ financial difficulties There is little practical need in all methods of controlling brain growth, including sex, sex, and sex.

Turbo, Astreasnails, some blemishes and some tangs are good herbivores (algae), and snails are the most widely used scavengers, ^ And usually the best choice; some countries seem to expect __ and dwarf angelfish (adding angels) to clear the vines. The former is easy to die and will move the decorations in the aquarium. The latter problem is that it needs to be expensive to feed. Invertebrates. Current more advanced methods include functional protein removal equipment (hungry equipment, protein applicators), some with ozone and UV sterilization; these physical filters remove and destroy vines exposed to water, and help spread Water (4) nutrient oxidation and circulation. For the effect of long-term and long-term effects, the use of any compound to control algae growth is the least desirable. There are several brands of antibiotics on the city φ (erythromycin, or equivalent common name ^ All opinions or statements (4) are intended to avoid antibiotics. Antibiotics only target symptoms, but do not eradicate algae. The cause of algae may be derived from system=unbalance, so the obvious side effect of using antibiotics is to change the water. Systematize the European/Suihua, don't forget that antibiotics (anti-bi〇tic) means "confrontation-life." Copper products sold in commercial and public aquariums are usually in the form of copper sulphate solution. Killing _ is also a parasitic preventive for animal-like epidemics. If there are plans, stay, vertebrate, giant _, live rock in the secret, do not make the product in the mouth. _ metal is an excellent therapeutic agent, and It can be used to prevent sinks, water hangings, fish-only rainbow towels (four) face-to-face; widely used in the market to make bribes an algicide, but for all life is _ sexually poisonous (four), especially non-fish _ If you use a chemical algicide, you need to pay special attention to the dosage, which should be lower than the dose that will cause acute and toxic side effects. There are several products marked in the "poor situation", the agent can double or triple Gamma, which leads to the implementation of _ control and subsequent inconvenience. 1284510 The part of the abaticide that is broken is in the form of an aqueous solution. In the form of an aqueous solution = two = not the efficiency of eradicating algae; for example, a liquid killer Injury, I include sodium hypochlorite, which limits the shelf life of the algicide. The general term is that if a large amount of algicide component is required, it is unfavorable to transport it in the form of an aqueous solution. The aqueous solution contains about ten percent of the sodium lactate. If it is in the form of a concentrated solid algicide, it may be transported more easily. SUMMARY OF THE INVENTION The present invention is used to inhibit growth. The composite material comprises: a mixture of a porous metal matrix and a silk metal mixture covering the surface; wherein the mixture comprises nano metal particles and a substance which fixes the nano metal particles (4). In the present invention, the composition may be any nano metal suitable for carrying the present invention. The following examples, m, shout, oxidized metal, plastic and polymer, may be applied to the present invention. The embodiment is a porous base rhyme; a better embodiment is a fine shout; the best solid is that the carrier is a ceramic stone type water filter. Nano silver has long known that silver It can inhibit the oxygen exchange of bacteria and kill the bacteria. The silver can be directly combined with the oxygen metabolism enzyme (-SH), so that the bacteria can not breathe, resulting in the majority of microbes that are fine with nano silver, including Bacteria, epiphytes, molds and spores. Nanosilver has complete antibiotic activity against pathogenic bacteria that are resistant to resistance 'eg, colibacillus, resistant Staphylococcus aureus Cstaphyl (xx) CCUS Aureus), drug-resistant Pseudomonas aeruginosa (10) _ ae aeruginosa, py〇c〇ccus, drug-resistant enterobacteria ((5) bacilli) and anaerobic bacteria (anaer〇bes). Nano silver can kill bacteria attached to burns or wounds, such as: Staphylococcus aureus, Enterobacter, Pseudomonas aeruginosa, white rosary, killing his Granny & Pathogenic bacteria, can also substantially kill pathogenic bacteria that multiply in the reproductive tract, such as gonorrhea.
