4256 results about "Disinfectant" patented technology

Disinfectants are antimicrobial agents that are applied to the surface of non-living objects to destroy microorganisms that are living on the objects. Disinfection does not necessarily kill all microorganisms, especially resistant bacterial spores; it is less effective than sterilization, which is an extreme physical and/or chemical process that kills all types of life. Disinfectants are different from other antimicrobial agents such as antibiotics, which destroy microorganisms within the body, and antiseptics, which destroy microorganisms on living tissue. Disinfectants are also different from biocides — the latter are intended to destroy all forms of life, not just microorganisms. Disinfectants work by destroying the cell wall of microbes or interfering with their metabolism.

Nanosilver-containing antibacterial and antifungal granules and methods for preparing and using the same

The present invention relates to nanosilver-containing antibacterial and antifungal granules ("NAGs"). The NAGs have longlasting inhibitory effect on a broad-spectrum of bacteria and fungi, which include, but are not limited to, Escherichia coli, Methicillin resistant Staphylococcus aureus, Chlamydia trachomatis, Providencia stuartii, Vibrio vulnificus, Pneumobacillus, Nitrate-negative bacillus, Staphylococcus aureus, Candida albicans, Bacillus cloacae, Bacillus allantoides, Morgan's bacillus (Salmonella morgani), Pseudomonas maltophila, Pseudomonas aeruginosa, Neisseria gonorrhoeae, Bacillus subtilis, Bacillus foecalis alkaligenes, Streptococcus hemolyticus B, Citrobacter, and Salmonella paratyphi C. The NAGs contain ground stalk marrow of the plant Juncus effusus L. which has been dispersed with nanosilver particles. The nanosilver particles are about 1-100 nm in diameter. Each of the nanosilver particles contain a metallic silver core which is surrounded by silver oxide. The present invention also provides a process for making the NAGs. The NAGs can be used in a variety of healthcare and industrial products. Examples of the healthcare products include, but are not limited to, ointments or lotions to treat skin trauma, soaking solutions or cleansing solutions for dental or women hygiene, medications for treating gastrointestinal bacteria infections, sexual related diseases, and eye diseases. Examples of industrial products include, but are not limited to, food preservatives, water disinfectants, paper disinfectants, construction filling materials (to prevent mold formation).

Aquosity bi-component polyurethane coloured paint and method of manufacturing the same

The invention discloses a two-component waterborne polyurethane colored paint and the preparation method. The components of the paint are 5 to 15 water, 0.2 to 0.5 dispersant, 0.1 to 0.3 antifoamer, 0.1 to 0.3 wetting agent, 3 to 25 paints, 0 to 50 fillers, 10 to 80 film forming resins, 0 to 5 film forming additives, 0.1 to 0.3 disinfectant, 0.1 to 0.3 antiflash rust agent, 0.5 to 2 thickeners, 1 to 20 hydrophilically-modified polyisocyanate. The preparation method is that water, dispersant, antifoamer, wetting agent, paints and fillers are dispersed evenly by a sand mill, a ball mill or a high-speed stirrer after stirring, and are added with film forming resins, film forming additives, disinfectant, antiflash rust agent and thickeners to gain the product-component A. The hydrophilically-modified polyisocyanate is component B. The component A and component B are mixed uniformly when using. The invention is characterized in that the invention does not adopt organic solvents, does not contain toxic paints and has no harm on the human body and environment, and the properties can reach the solvent two-component polyurethane paint, which can be produced to the primer, intermediate coat and finishing coat, and can be applied in the surface of the wooden ware, cement and metals.

Medical instrument sterilization, cleaning and drying integral equipment

The invention discloses medical instrument sterilization, cleaning and drying integral equipment which comprises a tank body, a threaded rod, a first motor, a movable block, a rotating shaft, a spring, a holding frame, a gear, a sterilization device, a cleaning device, a drying device, a collecting frame and a rack, wherein the sterilization device comprises a disinfectant tank, a first pump body,a second motor and a brush plate; the cleaning device comprises a water tank, a second pump body and a cleaning plate; the drying device comprises a drying plate, a drying lamp and an ultraviolet raysterilization lamp. Due to adoption of the sterilization device, a disinfectant can be sprayed while a medical instrument is brushed, so that the sterilization effect is improved; due to adoption ofthe cleaning device, the disinfectant is prevented from being retained on the medical instrument to do harm to skin of medical operators; due to adoption of the drying machine, two drying modes are implemented simultaneously, so that a rapid drying speed and a good drying effect are achieved; due to adoption of the gear and the rack, a medical instrument in the holding frame can automatically slide into the collecting frame conveniently and rapidly, and meanwhile the consequence that the medical instrument is contaminated again as operators contact the medical instrument is avoided.

Rice nursery sock growing seedling strengthen agent and method for using

InactiveCN101113122AWith water retentionRoot-promotingFertilizer mixturesGrowth plantDisinfectant
The rice plant cultivation and strengthening agent and using method thereof relate to plant cultivation and strengthening agent and using method thereof, which solves the problems of less nutrition content, larger dosage, high production and transport cost, high labor intensity and complexity in fertilization, labor and time consumption in prior rice plant cultivation and strengthening agent. The rice plant cultivation and strengthening agent comprises nutrition elements, flavohumic acid, acid regulating agent, sequestering agent, water conservation agent, disinfectant, plant growth regulator, phlogiston, mould inhibitor, and additive. The using method is that: 1. the rice plant cultivation and strengthening agent is added with water in a proportion of 1 to 1000 times; 2. the solution is applied in the land with a proportion of 500g of the agent to 50m2 of the land; 3. the rice is planted when the agent is fully permeated in the soil. The rice plant cultivation and strengthening agent of the invention has high content of nutrition and the dosage of 10g in 1m2 land, thereby reducing production and transport cost and labor intensity in fertilization. The using of the rice plant cultivation and strengthening agent combines the fertilization, pH regulation, disinfection and first watering together, which is of time and labor saving.

Composition for disinfection of plants, animals, humans, byproducts of plants and animals and articles infected with pathogens and method of producing and application of same

ActiveUS7163709B2Extended shelf lifeReduce pathogensBiocideFatty acid chemical modificationDiseaseIrrigated crops
The present invention discloses a composition and method of providing ionic forms or compounds of any combination of three metals to produce a product that can be used as a antimicrobial as defined by the U.S. Environmental Protection Agency (EPA) such as a hard surface disinfectant and as a foliar spray or water treatment for the control of various diseases in garden row, field and tree crops, on hard surface areas such as equipment from infected fields or in hospitals, homes, etc. as well as against a wide range of human, plant and animal diseases. Additionally, the composition of the present invention is able to be used to coat and otherwise treat and disinfect food products such as but not limited to fish and shellfish, meat, milk, poultry, eggs and irrigated crops (both food and nonfood crops) as well as non food products as defined in the EPA exemption from tolerance for copper and copper products. The composition may include inerts such as surfactants, detergents and buffers to adjust the pH. The composition remains soluble in water and is useful efficacious against the spread of bacteria, viruses and fungi and other pathogens within a source of water such as a reservoir or pool. Alternatively, the composition may be in aerosolized, misted, vaporized, fogged, humidified forms to produce micronized particles which are able to remain in suspension in the air for long periods of time in order to act on air-borne fungal spores and/or pathogens.
