Description
Technical field
The invention belongs to plastic-spraying processing technique fields, and in particular to a kind of high stability workmanship of spraying plastics method.
Background technology
Coating, in the entitled paint of Chinese tradition.So-called coating be coated in the body surface being protected or decorated, and
The continuous film of firm attachment can be formed with coated article, typically based on resin or oil or lotion, add or do not add face
Material, filler add corresponding additive, the thick liquid being formulated with organic solvent or asbestos.Chinese coating circle is more authoritative
《Coating process》What one book was defined as：" coating is a kind of material, and this material can be coated in different construction technologies
Object surface is formed and is adhered to securely, with some strength, continuous solid film.The film common name film formed in this way, is also known as painted
Film or coating." paint finishing can bond with basis material and be formed the material of complete and tough and tensile protective film very well in body surface,
Referred to as coating.Coating and paint are identical concepts.Paint is people's custom title used for a long time, after introducing China, just always
Using in building trade.The effect of coating may be summarized to be three aspects：Protective effect, decoration function, specific function effect.It applies
The general composition of material：Including film forming matter, color stuffing, solvent, auxiliary agent.
Coating refers to the general name that can form the material of tough and tensile protective film applied to body surface, and building coating is in coating
An important class will generally be used for building plastic-spraying in China, exterior wall, ceiling, ground, the coating of toilet is known as building
Build coating.Plastic-spraying is a kind of surface treatment method on part by plastispray.Plastic-spraying namely we often say it is quiet
Electro-powder spray-coating.
Plastic-spraying is so that plastic powders is charged using electrostatic generator, is adsorbed on the surface of iron plate or other products, then passes through
The baking for crossing 200 DEG C or so, makes powder fusing be attached on the surface of metal or other objects, and plastic-spraying product is chiefly used in indoor make
Zero diopter or matte effect is presented in babinet, paint film.Plastic-blasting coating mainly has acrylic clear powder, polyester powder etc..But it is existing
Plastic-blasting coating used in plastic-blasting method has that water resistance, scrubbing resistance wearability, weatherability etc. are bad more, and sprays
The technique for moulding processing is relatively simple, causes the workpiece quality of final process that the design and use that people are increasingly promoted are not achieved and wants
It asks, continuous improvement is needed to handle.
