Classification knowledge of Low price Metal coating manufacturers
Low price Metal coating manufacturers are coatings with metallic texture, most of which require some form of pretreatment on the metal surface to improve the surface condition, in order to improve the adhesion of the coating and enhance the anti-corrosion protection of the metal substrate. So how much do you know about the classification knowledge of Low price Metal coating manufacturers? Let’s take a look at it briefly below!
Metals mainly include ferrous metals and non-ferrous metals; ferrous metals generally refer to steel (such as cast iron, wrought iron, carbon steel, mild steel, etc.); non-ferrous metals generally refer to non-ferrous metals that often have certain colors, such as Aluminum, copper, lead, zinc, chromium, gold, silver and their coatings, etc.
Non-ferrous metals generally do not need to be painted with paint protective coatings. This is because some non-ferrous metals are chemically inert and inert, and are not prone to corrosion; other non-ferrous metals are as susceptible to corrosion by active substances in the environment as ferrous metals. , but the deposits generated after they are corroded will firmly adhere to the metal surface to form a dense protective film, so that the metal body will no longer be corroded, or the corrosion rate will be quite slow, which objectively causes the metal body to be subjected to a certain degree of corrosion. degree of protection.
There are countless types of metal products, and therefore a wide variety of coatings used. Academically, there are many opinions on the classification of paint varieties: some advocate classification according to chemical structure; some advocate classification according to construction method; some advocate classification according to industry and liver use. As far as Low price Metal coating manufacturers are concerned, it has been determined that the coating object is the category of metal, so it is better to use the industry-specific classification method.
