Urinal Cakes
Urinal deodorizer blocks (commonly known as urinal cakes, urinal cookies, urinal biscuits (or jocularly piscuits), urinal donuts, toilet lollies, trough lollies, urinal pucks, toilet pucks, or urinal peons (alternately urinal pee-ons)) are small disinfectant blocks or tablets that are added to urinals. As these products originally contained para-dichlorobenzene (pDCB) they may also be called para blocks. Besides disinfecting, the purpose of these materials is to deodorize restroom urinals. They are placed above the urinal drain, often in the confines of a small plastic device called a ''urinal screen'' that prevents loss down the drain when they dissolve down to a small size. Chemistry The chemicals composing the block vary. The original formulations were based upon naphthalene and then later para-dichlorobenzene, both now known to be hazardous to health by inhalation. In some areas, the use of para-dichlorobenzene-based blocks has been banned; in other areas para-dichlorobenze ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Urinal With Urinal Cake Gsu Cit 2004
A urinal (, ) is a sanitary plumbing fixture similar to a toilet, but for urination only. Urinals are often provided in men's public toilet, public restrooms in Western world, Western countries (less so in Muslim world, Muslim countries). They are usually used in a standing position. Urinals can be equipped with manual flushing, automatic flushing, or without flushing, as is the case for waterless urinals. They can be arranged as single sanitary fixtures (with or without privacy walls), or in a trough design without privacy walls. Urinals designed for females ("female urinals") also exist but are rare. It is possible for females to use stand-up urinals using a female urination device. The term "urinal" may also apply to a small building or other structure containing such fixtures. It can also refer to a small container in which urine can be collected for urinalysis, medical analysis, or for use where access to toilet facilities is not possible, such as in small aircraft, during ...

Trap (plumbing)
In plumbing, a trap is a U-shaped portion of pipe designed to trap liquid or gas to prevent unwanted flow; most notably sewer gases from entering buildings while allowing waste materials to pass through. In oil refineries, traps are used to prevent hydrocarbons and other dangerous gases and chemical fumes from escaping through drains. In heating systems, the same feature is used to prevent thermo-siphoning which would allow heat to escape to locations where it is not wanted. Similarly, some pressure gauges are connected to systems using U bends to maintain a local gas while the system uses liquid. For decorative effect, they can be disguised as complete loops of pipe, creating more than one U for added efficacy. General description In domestic applications, traps are typically U, S, Q, or J-shaped pipe located below or within a plumbing fixture. An S-shaped trap is also known as an S-bend. It was invented by Alexander Cumming in 1775 but became known as the U-bend followi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Toilets
A toilet is a piece of sanitary hardware that collects human waste (urine and Human feces, feces) and sometimes toilet paper, usually for disposal. Flush toilets use water, while dry toilet, dry or non-flush toilets do not. They can be designed for a sitting position popular in Europe and North America with a toilet seat, with Accessible toilet, additional considerations for those with disabilities, or for a squatting posture more popular in Asia, known as a squat toilet. In urban areas, flush toilets are usually connected to a sewer system; in isolated areas, to a septic tank. The waste is known as ''Blackwater (waste), blackwater'' and the combined effluent, including other sources, is sewage. Dry toilets are Pit latrine, connected to a pit, Container-based sanitation, removable container, Composting toilet, composting chamber, or other storage and treatment device, including urine diversion with a Urine-diverting dry toilet, urine-diverting toilet.

Hygiene
Hygiene is a set of practices performed to preserve health. According to the World Health Organization (WHO), "Hygiene refers to conditions and practices that help to maintain health and prevent the spread of diseases." Personal hygiene refers to maintaining the body's cleanliness. Hygiene activities can be grouped into the following: home and everyday hygiene, personal hygiene, medical hygiene, sleep hygiene, and Food safety, food hygiene. Home and every day hygiene includes hand washing, respiratory hygiene, food hygiene at home, hygiene in the kitchen, hygiene in the bathroom, laundry hygiene, and medical hygiene at home. And also environmental hygiene in the society to prevent all kinds of bacterias from penetrating into our homes. Many people equate hygiene with "cleanliness", but hygiene is a broad term. It includes such personal habit choices as how frequently to take a shower or bath, wash hands, trim Nail (anatomy), fingernails, and wash clothes. It also includes atte ...

Toilet Rim Block
A toilet rim block is a substance in the shape of a block that is used in flush toilets, which slowly dissolves in water. The blocks usually come in a small holder that is attached over the rim of a toilet and hangs down into the bowl, so as the toilet gets flushed, the water passes through the holder coming into contact with the block. With "liquid rims", however, liquid is held in a small bottle above—and connected to—the holder that slowly releases into the bottom of the holder (which is beneath the toilet rim), and so coming into contact with the water when the toilet is flushed. However, the blocks also come ''loose'', for placement directly ''in-cistern'' (and therefore usable with squat toilets that lack the same sort of rim), although these tend to be slightly different in composition, so as to dissolve slower, due to the constant contact with water. These may also contain a colorant (typically blue or green) which shows up in the pan or bowl water. Composition and a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Air Freshener
Air fresheners are products designed to reduce unwanted odors in indoor spaces, to introduce pleasant fragrances, or both. They typically emit fragrance to mask odors but may use other methods of action such as absorbing, bonding to, or chemically altering compounds in the air that produce smells, killing organisms that produce smells, or disrupting the sense of smell to reduce perception of unpleasant smells. There are many different types of air fresheners that deliver their active ingredients in different ways, including sprays, candles, reed diffusers, scented beads, gels, passive and active evaporating diffusers, atomizers, automatically timed metered aerosol dispensers, electric fan air fresheners, and plug-ins. Air fresheners are used in domestic and commercial settings and in both small and large spaces. Some air fresheners are produced for specific spaces and odors, such as Car Freshner, car fresheners and urinal deodorizer blocks. Some air fresheners contain ingredients t ...

Quaternary Ammonium Compound
In organic chemistry, quaternary ammonium cations, also known as quats, are positively-charged polyatomic ions of the structure , where R is an alkyl group, an aryl group or organyl group. Unlike the ammonium, ammonium ion () and the primary, secondary, or tertiary ammonium cations, the Quaternary compound, quaternary ammonium cations are permanently charged, independent of the pH of their solution. Quaternary ammonium salts or quaternary ammonium compounds (called quaternary amines in oilfield parlance) are salt (chemistry), salts of quaternary ammonium cations. Polyquaternium, Polyquats are a variety of engineered polymer forms which provide multiple quat molecules within a larger molecule. Quats are used in consumer applications including as antimicrobials (such as detergents and disinfectants), fabric softeners, and hair conditioners. As an antimicrobial, they are able to inactivate viral envelope, enveloped viruses (such as SARS-CoV-2). Quats tend to be gentler on surfaces th ...

Waterless Urinal In City University Of Hong Kong
A substance is anhydrous if it contains no water. Many processes in chemistry can be impeded by the presence of water; therefore, it is important that water-free reagents and techniques are used. In practice, however, it is very difficult to achieve perfect dryness; anhydrous compounds gradually absorb water from the atmosphere so they must be stored carefully. Solids Many salts and solids can be dried using heat, or under vacuum. Desiccators can also be used to store reagents in dry conditions. Common desiccants include phosphorus pentoxide and silica gel. Chemists may also require dry glassware for sensitive reactions. This can be achieved by drying glassware in an oven, by flame, or under vacuum. Dry solids can be produced by freeze-drying, which is also known as lyophilization. Liquids or solvents In many cases, the presence of water can prevent a reaction from happening, or cause undesirable products to form. To prevent this, anhydrous solvents must be used when performing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
