Classification of Siluoer texture preparation coating
Texture preparation coating has a long history of application and has a wide range of applications, with nearly a thousand species. According to the habit of long-term composition, there are the following classification methods.
According to the shape of the paint, it is divided into solvent-based soil, high-solids coating, water-based coating, non-aqueous dispersion coating and powder coating. Among them, the non-water-dispersive paint is similar to the latex paint. The difference is that the latex paint is water-dispersed medium, the resin relies on the effect of the emulsifier to disperse in the water to form an oil/water layout emulsion, and the non-water-dispersive paint is an aliphatic hydrocarbon as a dispersion medium. , constitutes an oil/oil emulsion. High solids coatings are generally coatings with a solids content of more than 70%.
According to the classification of paints, it is divided into construction coatings, industrial coatings and maintenance coatings. Industrial coatings include automotive coatings, marine coatings, texture preparation, aircraft coatings, wood coatings, leather coatings, paper coatings, coil coatings, plastic coatings and other industrial coatings. Coil coatings are used to produce pre-coated coils. The pre-coated coils are organic materials/metal sheets that are sold in rolls or sheets after the rolled metal sheets are coated or laminated with a plastic film. It is also known as an organic coated steel plate, a colored steel plate, a plastic composite steel plate, etc., and can be directly processed and formed without further painting. Pre-coated coils are primarily used for roofing or walling of buildings.
According to the film coating function, there are anti-rust paint, anti-corrosive paint, insulating paint, anti-fouling paint, high temperature resistant paint, conductive paint and so on. Paints in the coatings industry are primarily of two broad categories: primers and topcoats. The primer pays attention to the adhesion and anti-corrosion maintenance effect: the topcoat pays attention to the embellishment and the field maintenance effect. The two are used together to form a consolidated coating, but the composition is very different. Topcoats should have outstanding embellishment and maintenance functions. The topcoats are often made into enamels (also known as enamels). The lacquers are made of light-resistant and highly pigmented paints. The paint film is generally flat and lubricious, and is as strong as porcelain. .
According to the construction method, there are spray paint, dip paint, electrophoretic paint, baking paint and so on. Sand spray coating sprayed on the spray booth with a spray gun. The impregnating varnish is to put the workpiece into the container of the paint to coat the paint. The water-soluble paint applied by electrophoresis is called electrophoretic paint. Baking paint refers to the type of coating that needs to be baked at a certain temperature to dry and form a film. In particular, it is a type composed of two or more kinds of film-forming substances. It does not resonate at room temperature, as long as it is baked to make the intermolecular The functional group attacks the cross-linking reaction to form a film.
According to the film formation mechanism, there are conversion coatings and non-converted soils. Non-converting coatings are thermoplastic coatings, including volatile coatings, thermoplastic powder coatings, texture preparation, latex paints, and the like. Conversion coatings include air drying coatings, curing agent curing dry coatings, baking cured coatings and radiation curing coatings. Air drying is self-drying of the coating and the oxygen or moisture in the air at room temperature after painting.
