Pvcpedie

PVC comes in two basic forms: rigid (sometimes abbreviated as RPVC) and flexible. The rigid form of PVC is used in construction for pipe and in profile applications such as doors and windows. It is also used in making bottles, non-food packaging, food-covering sheets, and cards (such as bank or membership cards). A premature ventricular contraction ( PVC ) is a relatively common event where the heartbeat is initiated by Purkinje fibers in the ventricles rather than by the sinoatrial node. PVCs may cause no symptoms or may be perceived as a skipped beat or felt as palpitations in the chest.

Single beat PVCs do not usually pose a danger. PVC plastic is often called vinyl and this type of clothing is commonly known as vinyl clothing. PVC is sometimes confused with the similarly shiny patent leather. The terms PVC , vinyl and PU tend to be used interchangeably by retailers for clothing made from shiny plastic-coated fabrics.

Chlorinated polyvinyl chloride (CPVC) is a thermoplastic produced by chlorination of polyvinyl chloride ( PVC ) resin, which is significantly more flexible and can withstand higher temperatures than standard PVC. Uses include hot and cold water delivery pipes and industrial liquid handling. Polyvinyl chloride, also called Polychloroethene or PVC , is a thermoplastic. It turns soft when heated and hard when cooled. PVC can be made softer and more flexible by adding plasticizers.

Plastic pipe is a tubular section, or hollow cylinder, made of plastic. It is usually, but not necessarily, of circular cross-section, used mainly to convey substances which can flow—liquids and gases (fluids), slurries, powders and masses of small solids. What are the dangers of PVC?

How is polyvinyl chloride made? The C-Cl bonds in the backbone are hydrophobic and resist oxidation (and burning). PVC is stiff, strong, heat and weather resistant, properties that recommend its use in devices for plumbing, gutters, house siding, enclosures for computers and other electronics gear.

Polyvinylchlorid ( PVC ) je třetím nejpoužívanějším plastem na Zemi, hned po polyethylenu a polypropylenu. Není rozpustný ve vodě, v olejích ani v koncentrovaných anorganických kyselinách a zásadách. Nominal Pipe Size (NPS) is a North American set of standard sizes for pipes used for high or low pressures and temperatures.

Nominal refers to pipe in non-specific terms and identifies the diameter of the hole with a non-dimensional number (for example – 2-inch nominal steel pipe consists of many varieties of steel pipe with the only criterion being a 75-inch (6 mm) outside diameter). The Free Encyclopedia. Omdat pvc goedkoop en eenvoudig te bewerken is, wordt het veel toegepast in allerlei takken van de industrie ter vervanging van onder andere hout en beton.

Initialism of premature ventricular contraction. A plastic is a material that can change its shape. Many things are made of plastics, usually because making them to the right shape is easy. There are many types of plastic.

Polivinilklorid (okrajšano PVC ), sistematično poli(1-kloroeten), je sintetičen plastični polimer vinil klorida, za polietilenom in polipropilenom tretji najbolj množično proizvajan tip plastike in široko uporabljan v sodobnem svetu kot material za izdelavo številnih uporabnih predmetov. Polyvinyl Chloride ( PVC ) is one of the most widely used polymers in the world. Hård PVC og blød PVC.

Eksempler på hårde PVC -produkter er rør, vinduer, kabelbakker og profiler. Det, der adskiller de bløde fra de hårde PVC -produkter, er, at kun de bløde. BO- PVC Leg warmers. GL- Kinky Vinyl Gloves.
