PVC full form pipe

PVC full form pipe: Polyvinyl Chloride.


Polyvinyl chloride also known as PVC is a kind of synthesised plastic polymer. That is used in a lot of tools, mostly used in constructions. Moreover, PVC acquires the third position in terms of its uasability metrics. Being the third most popular polymer in the world. The industries linked with it, are making tremendous profits. Industries that are involved in plumbing, fitting, pipes and tool making. Are its main utilizers and modifiers. It has many reasons of its popularity, but its strength and flexibility are the main among all. Coming to its manufacturing amount, about 44 million tons of it, are produced every single year.


According to Wikipedia, PVC had an accidental discovery. Eugen Baumann, a chemist from Germany is known to do that. The accident was simply a chemical reaction. Moreover, the very first polymer of this kind appeared as a white colored solid. That took its form under the presence of sunlight. So, the very first PVC appeared to be a white colored substance, inside a container. Containing vinyl chloride and was exposed to sunlight for a long time. It was sometime in the year of 1926, Goodrich company along with Semon's efforts. Modified the old styled PVC, giving it rigidity, strength and flexibilty. With the release of this modified form, it have boomed the manufacturing industry related with it. However, knowing PVC full form pipe is worth it.



PRODUCTION OF THE PVC:


Coming to the production process involved. PVC is produced through a step by step process in the concerned industries.


1. Above all, the basic raw materials used in its production are extracted from salt and oil. Chlorine, the most important one is derived from the electrolysis of sodium chloride (NaCl). Having a primary requirement of salt everytime in its production process. Most of PVC producing industries are generally made. Near to places, with high salt concentration.

2. Coming to the step by step process. At the very initial times, the electrolysis of salt water or NaCl solution is done. This process gives out the chlorine for further processes. This chlorine is then added with ethylene, to make a new mixture. Moreover, this ethylene was earlier extracted from the oil. Consequently, the mixture gives out the compound, named as ethylene dichloride.

3. Going to the next series of steps. Once, the ethylene dichloride is derived by the mentioned processes. It is then thrown into extremely high temperature. And that results its conversion, to the vinyl chloride monomer. Ultimately, when the monomer gets formed. It is then polymerized to obtain the polyvinyl chloride resins. That is again refined to obtain the usable polyvinyl chloride from it. However, knowing PVC full form pipe is worth it.



ADDITIVES USED IN THE FINAL PVC:


Sometimes, PVCs are found to react against sunlight and its ultraviolet radiations. This makes them unstable and they couldn't exist any long. In order to add stability and usability to such products. A variety of additives are present in manufactured products. This helps them remain stable and remain in the solid state.


Some of the most used additivies are as follows:


1. Anti-oxidants and stabilizers: These are chemicals cum compounds. Used to either prevent oxidation or to stabilize the products. The main function of these additives is to delay the rate of degradation of the polymer. All by heat, light, oxygen in air or by the sun's ultraviolet radiations.

2. Compatibilizers: These are the industrial additives, that makes good quality mixtures. These additives mixes the hard poly vinyl chlorides with the plastics. Moreover, they also assists the processes involvd in the recycling of plastics.

3. Flame retardants: As the name suggests, these additives works to retard processes. Most importantly, flame retardants decreases the flammability of plastics and polymers.




THE OTHER FOUR MEMEBERS OF THE LIST:


4. Pigments: Pigments are neutral additives. That is, they never cause any changes to the products physically. These additives dyes products, mainly plastics. Apart from imparting visible colors, these additives doesn't cause any reactions.

5. Plasticisers: These are worthful additives. In order, to produce useful plastics out of something. Plasticisers is the best option. Moreover, they do make flexible, useful and manageable palstics.

6. Impact modifiers: They produce strong and sound final products. These actually helps the product to absorb shock and vibrations. Without any kind of serious damage.

7. Filters: These things adds weight to the products. Filters are simply inert substances. And adds bulk/weight to the plastics. Plastics, are generally light weight. So, adding some weight to them is fruitful and gentle.



APPLICATIONS OF THE PVC:


1. Pipes: World's fifty percent of PVC is to make pipes out of it. These pipes are extremely rigid and strong. The only reason, being its usage in underground and underwater pipelines. Since, PVC supports easy cutting and joining. PVC pipes are the most convenient to build networks of underground and underwater pipe networks.

2. Cables: Another important use of it, is in making cables. Most importantly, the PVC acts as an isulation coating on them. And for this plasticised PVC cables are a must. With the use of PVC on the open conducing wires, electricians are able to use them without receiving any electric shock.

3. Construction: PVC plays a major role in making good homes. Particularly in building the pipelines in them. PVCs are light in weight but are strong. Moreover, plasticizing them makes them flexible. So, a large number of U.S, Ireland and Canada households uses them as a major component.

4. Clothing: PVC is a major part of certain cloth types. However, most of them are water proof materials. Used in making raincoats, umbrellas, gumboots, raincoats and aprons. PVC is light weight and have a specific role in such type of clothes. Moreover, its low price, availability and smothness makes them highly preferable. However, experts believes it to be the best among its rivalry polymers.



PROS OF THE PVC PIPE:

  • Manufactured by several thermoplastic and plastisol methods.
  • PVC pipes could be ultra-flexible. Simply by varying the levels of plasticizers.
  • Most of the PVC pipes are non flammable in nature.
  • All of the maufactured PVC products are dimensionally stable. If not, adding certain additives will stabilize them.
  • The final products costs comparatively low than other rivalries. Moreover, they are highly resisitive to water and bad climate (mostly rainy season).






CONS OF THE PVC PIPE:

  • Different industrial solvents can damage them. This may cause serious decaying and utimately huge losses.
  • They can resist heat upto a certain limit only. Once, exposed to high temperature, can cause leakage or damage.
  • Moreover, the decomposition of such materials could emitt toxic gases like HCl and others. That is very bad for the air to breathe.
  • Their high density takes long time for degradation. However, the industry linked with its manufacturing emitts toxic wastes. That simply pollutes the soil, water and air collectively.
