Vapor Steam Cleaners
Vapor steam cleaners or steam vapor systems are cleaning appliances or devices that use steam to quickly dry, clean, and sanitize surfaces. The steam is produced in a boiler that heats tap water to high temperatures (240–310F/115–155°C) to produce low-pressure, low moisture (4% to 6% water) water vapor. Operation The steam's ability to clean is based primarily on its heat. The steam is applied to cleanable surfaces via a variety of insulated tools and accessories, releasing contaminants into water suspension, after which they can be removed by wiping or vacuuming. Advantages Vapor steam cleaners consume less water compared to carpet cleaners or other cleaning devices, which use hot water instead of steam. They can also remove excess vapor from the air. A vapor steam cleaner can help to remove scents absorbed by materials. Applications The low-moisture characteristics of vapor steam cleaners make them suitable for use inside buildings and residences. Vapor st ...

Viruses
A virus is a submicroscopic infectious agent that replicates only inside the living cells of an organism. Viruses infect all life forms, from animals and plants to microorganisms, including bacteria and archaea. Since Dmitri Ivanovsky's 1892 article describing a non-bacterial pathogen infecting tobacco plants and the discovery of the tobacco mosaic virus by Martinus Beijerinck in 1898,Dimmock p. 4 more than 9,000 virus species have been described in detail of the millions of types of viruses in the environment. Viruses are found in almost every ecosystem on Earth and are the most numerous type of biological entity. The study of viruses is known as virology, a subspeciality of microbiology. When infected, a host cell is often forced to rapidly produce thousands of copies of the original virus. When not inside an infected cell or in the process of infecting a cell, viruses exist in the form of independent particles, or ''virions'', consisting of (i) the genetic material, i.e ...

Hot Water Extraction
Hot Water Extraction (HWE) is a method of carpet cleaning. It involves a combination of hot water and cleaning agents being injected into the fibers of a carpet at high pressure and the lifted soil being removed by a powerful vacuum. Process Though commonly called "steam cleaning", no actual steam is involved in the HWE cleaning process apart from steam that may escape incidentally from hot water. When the cleaning solution comes in contact with the carpet, it is 50 to 120 degrees Celsius, depending on the heat available from the cleaning unit. In a modern truck-mounted carpet cleaning machine, water can be heated under pressure to over 150 degrees Celsius, but after passing through high-pressure steel braided hoses and several manifolds, the water loses much of its heat. HWE begins with preconditioning using a pre-spray cleaner (typically neutral or alkaline) being applied to the soiled surface, followed by light agitation with a grooming or pile brush. For heavily soiled area ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Green Cleaning
Green cleaning refers to using cleaning methods and products with environmentally friendly ingredients and procedures which are designed to preserve human health and environmental quality. Green cleaning techniques and products avoid the use of products which contain toxic chemicals, some of which emit volatile organic compounds causing respiratory, dermatological and other conditions. Green cleaning can also describe the way residential and industrial cleaning products are manufactured, packaged and distributed. If the manufacturing process is environmentally friendly and the products are biodegradable, then the term "''green''" or "''eco-friendly''" may apply. Product labeling programs Among the product-labeling programs is the United States Environmental Protection Agency's (EPA) Design for the Environment program which labels products that meet EPA's criteria for chemicals. These products are allowed to carry the Design for the Environment (DfE) label, renamed EPA Safer Choice ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Industrial Production
Industrial production is a measure of output of the industrial sector of the economy. The industrial sector includes manufacturing, mining, and utilities. Although these sectors contribute only a small portion of gross domestic product (GDP), they are highly sensitive to interest rates and consumer demand. This makes industrial production an important tool for forecasting future GDP and economic performance. Industrial production figures are also used by central banks to measure inflation, as high levels of industrial production can lead to uncontrolled levels of consumption and rapid inflation . See also *Index of industrial production The Index of Industrial Production (IIP) is an Index (economics), index for India which details out the growth of various sectors in an economy such as mineral mining, electricity and manufacturing.

Bio-contamination
A biological hazard, or biohazard, is a biological substance that poses a threat to the health of living organisms, primarily humans. This could include a sample of a microorganism, virus or toxin that can adversely affect human health. A biohazard could also be a substance harmful to other animals. The term and its associated symbol are generally used as a warning, so that those potentially exposed to the substances will know to take precautions. The biohazard symbol was developed in 1966 by Charles Baldwin, an environmental-health engineer working for the Dow Chemical Company on the containment products. It is used in the labeling of biological materials that carry a significant health risk, including viral samples and used hypodermic needles. In Unicode, the biohazard symbol is U+2623 (). ANSI Z535/OSHA/ISO regulation Biohazardous safety issues are identified with specified labels, signs and paragraphs established by the American National Standards Institute (ANSI). ...

Bacteria
Bacteria (; singular: bacterium) are ubiquitous, mostly free-living organisms often consisting of one biological cell. They constitute a large domain of prokaryotic microorganisms. Typically a few micrometres in length, bacteria were among the first life forms to appear on Earth, and are present in most of its habitats. Bacteria inhabit soil, water, acidic hot springs, radioactive waste, and the deep biosphere of Earth's crust. Bacteria are vital in many stages of the nutrient cycle by recycling nutrients such as the fixation of nitrogen from the atmosphere. The nutrient cycle includes the decomposition of dead bodies; bacteria are responsible for the putrefaction stage in this process. In the biological communities surrounding hydrothermal vents and cold seeps, extremophile bacteria provide the nutrients needed to sustain life by converting dissolved compounds, such as hydrogen sulphide and methane, to energy. Bacteria also live in symbiotic and parasitic relationsh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Steam
Steam is a substance containing water in the gas phase, and sometimes also an aerosol of liquid water droplets, or air. This may occur due to evaporation or due to boiling, where heat is applied until water reaches the enthalpy of vaporization. Steam that is saturated or superheated is invisible; however, "steam" often refers to wet steam, the visible mist or aerosol of water droplets formed as water vapor condenses. Water increases in volume by 1,700 times at standard temperature and pressure; this change in volume can be converted into mechanical work by steam engines such as reciprocating piston type engines and steam turbines, which are a sub-group of steam engines. Piston type steam engines played a central role in the Industrial Revolution and modern steam turbines are used to generate more than 80% of the world's electricity. If liquid water comes in contact with a very hot surface or depressurizes quickly below its vapor pressure, it can create a steam explosion. ...

Mold (fungus)
A mold () or mould () is one of the structures certain fungi can form. The dust-like, colored appearance of molds is due to the formation of spores containing fungal secondary metabolites. The spores are the dispersal units of the fungi. Not all fungi form molds. Some fungi form mushrooms; others grow as single cells and are called microfungi (for example yeasts). A large and taxonomically diverse number of fungal species form molds. The growth of hyphae results in discoloration and a fuzzy appearance, especially on food. The network of these tubular branching hyphae, called a mycelium, is considered a single organism. The hyphae are generally transparent, so the mycelium appears like very fine, fluffy white threads over the surface. Cross-walls (septa) may delimit connected compartments along the hyphae, each containing one or multiple, genetically identical nuclei. The dusty texture of many molds is caused by profuse production of asexual spores ( conidia) formed by di ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hypoallergenic
Hypoallergenic, meaning "below average" or "slightly" allergenic, is a term meaning that something (usually cosmetics, pets, textiles, food, etc.) causes fewer allergic reactions. The term was first used in 1953 in an advertising campaign for cosmetics or perhaps as early as 1940. The term is also commonly applied to pet breeds which are claimed to produce fewer allergens than other breeds of the same species, due to some combination of their coat type, absence of fur, or absence of a gene that produces a certain protein. All breeds still produce allergens and a 2011 study failed to find a difference in allergen concentrations in homes with dogs of "hypoallergenic breeds" and other breeds. Certifications and definitions In some countries, there are allergy interest groups that provide manufacturers with a certification procedure including tests that ensure a product is unlikely to cause an allergic reaction, but such products are usually described and labeled using other but sim ...
