PVC Pipe Manufacturing: The Making Of PVC Pipes In The Country
You may be familiar with the term PVC, especially in relation to things like construction, the most common form being PVC pipes. But, do you know anything else about the material, or how much is made and how much we've come to rely on it? Well, naples extrusion services is a practice that has been continually improving for decades, as well as the entire PVC industry. First of all, PVC is an acronym for polyvinyl chloride, and in raw form can be morphed into many products with long shelf lives and reasonable prices. You can find the material PVC in things that you wouldn't even think would hold it, like ceiling tiles, portable electronics, and signs that you see on the street. Over time, PVC has taken a huge lead in plastics manufacturing, and with its easy flexibility and manufacturing process, there's really no surprise why. It is even approximated that by 2016, production of PVC will exceed at least 40 million tons, looking at our current output.
As can be expected by the name, polyvinyl chloride is actually a vinyl polymer, made up of several vinyl groups (ethenyls). These vinyl groups have one of their hydrogens replaced with a chloride group, thus making PVC plastic. This plastic is so popular in the industry, that it is actually the third most widely used, with polyethylene and polypropylene coming in first and second. Not only is it such a breeze to make, but for specific products, in can be made to be more flexible and much softer with the use of plasticizers.
These plasticizers made it possible for companies to manufacture things such as flexible hoses, electrical cable insulation, and fabrics, which was favorable for a number of obvious reasons. The most commonly used plasticizer is called phthalates, and due to its low prices, it has been used widely in the production process ever since its introduction in the 1920's. So many more things can be made with this plasticized PVC, especially since it isn't ruined by water. This allows things like inflatable pool toys and waterbeds to be made durable and in huge quantities.
PVC has to go through a process to become what it is, often referred to as polymerization, and specifically the polymerization of VCM, or vinyl chloride monomer. Most manufacturers of the PVC material put it through a type of polymerization called suspension polymerization. In order to go about this, they must place raw VCM in a machine which takes it through a series of steps including intense pressure, heating, and shaping of the raw material. It is then taken out of the machine and put into a cooling container in order to retain its shape.
PVC was discovered by accident at least two different times during the 19th century; once in 1835 by Henry victor Regnault, and again in 1872 by Eugen Baumann. They found that when they left raw vinyl chloride monomer out in the sun, white chunks began to form along the inside of it. Neither men did anything with what they found however, and the process was not able to expand until the 20th century. Ivan Omstromislensky and Klatte attempted to manipulate the plastic but found it too impossible to work with.
Waldo Semon and the B.F. Goodrich Company came up with the idea of plasticizing the material with the use of different additives. They thought that this would dilute the material and make it more flexible and much easier to work with, and they were right. With the introduction of this plasticizing process in 1926, PVC was allowed to flourish at a completely new level. All of the different applications that were now made possible thanks to plasticization grew in huge demand, and companies had to step it up.
Half of all polyvinyl chloride material produced goes to the making of PVC pipes. These pipes have completely taken over industries such as the water distribution market and the sanitary sewer construction. The durability of these pipes allows them to be put through harsh conditions without cracking or breaking for long periods of time. Also, with a simple heating or concrete process, companies can connect several lengths of pipes together, cutting back on prices, saving time, and allowing PVC piping to run for miles underground.
As well as the wide use of hurricane panels, polyvinyl chloride shows up in so many other products that we have become extremely familiar with. For example, many advertising signs, and things on vehicles (such as stripes) employ the use of PVC. During the manufacturing process, it can be flattened, expanded, and dyed for almost no additional cost. Then this form of PVC is cut by a computer-controlled machine and sold in mass quantity.
It's simply unreasonable to suggest that we would not notice if gainesville polymer extrusion just stopped production tomorrow. Trusted injection molded parts have become essential to our way of life. Too often we take for granted what industries such as plastic product manufacturers provide for our ever-increasing demands.
