A plastic coating provides resistance from corrosion and impact to metals, glasses and other materials. A product that is coating with plastic will waterproof as well as durable. Coating can be used as a decorative finish for products.
In industries where durability matters like automotive, medical and construction industries, coating is very essential. Some of the tools used for plastic coating are discussed here.
Plastisol is a liquid compound at room temperature and it is making of vinyl. It can last for years and it becomes solid vinyl when heated. Is important to note that when plastisol turns into solid. Can not return to its liquid state.
It has the capacity to be formulat to specifications in line with FDA. Standards for contact with food and chemical as well as electrical requirements. Plastisol that is process can produce to a shiny matte finish. It is very good for dampening sound and electrical or thermal insulation. It can also be us to eliminate sharp ges on metals in order to get a perfect finish.
Powder Coating Plastic
Plastic powder coating involves the consistency of fine seaside sand prior to being process. It is convert into fluid by reactor that is referr to as fluidiz b. It gives a resulting coat that is glossy, tough and weather resistant. Vinyl powder coating is typically found on dishwater racks. Mical devices, outdoor furniture and cable TV wiring.
A fluidized bed is use for processing plastic powder that will use for coating. The bed of the reactor holds particles that are fluidized by a gas that passes through the vessel from the base of the tank. Subsequent to the rising of the bed to about 30%, the particles will start to resemble boiling water. This will lead to the preheating of the material and its dipping into the vessel. The powder then melts onto the material in order to form a coating.
Electric infra r ovens are usually us for curing parts that have been coat with plastic. The flexibility of the infra r emitters makes them preferable. Infra r ovens provide the best wavelength so that deeper penetration of the plastic and high radiant applications requir for majority of applications could be achiev.
It is important to wash all the items that are coat in advance of the process and the ovens are us to dry them.
