15% diluted nitro magnetized white water Polyester paint: it is a thick paint made of polyester resin as the main film-forming material The film of polyester paint is full and thick with hard surface Polyester paint also has a variety of varnish, called polyester varnish Polyester paint needs to be cured in the construction process, and the proportion of these curing agents accounts for one third of the total content of the paint These hardeners, also known as hardeners, are mainly TDI (toluene diisocyanate) These TDI in the free state will turn yellow, which not only makes the furniture paint surface standard, but also makes the adjacent walls turn yellow, which is a major disadvantage of polyester paint At present, yellow resistant polyester paint has appeared on the market, but only "yellow resistant" can be achieved It can't completely prevent yellowing In addition, the free TDI beyond the standard will cause harm to human body Polyurethane paint: polyurethane paint It has strong and tough paint film, full luster, strong adhesion, water resistance, wear resistance and corrosion resistance It is widely used in advanced wood furniture and metal surface The main disadvantages are foaming in case of damp, powdering of paint film, etc Like polyester paint, there is also the problem of yellowing The type of polyurethane varnish is called polyurethane varnish (2) Interior wall paint is mainly divided into water-soluble paint and emulsion paint Generally, emulsion paint is used for decoration Latex paint is a latex coating, according to the different substrates, divided into two categories: Polyester acid vinyl emulsion and acrylic emulsion Emulsion paint with water as diluent is a kind of paint with convenient construction, safety, washability and good air permeability Different colors can be prepared according to different color schemes Latex paint is mainly composed of water, pigment, emulsion, filler and various auxiliaries These raw materials are non-toxic, and the main toxic materials are glycol in film-forming agent and organic mercury in mildew inhibitor At present, the so-called "emulsion paint" which contains a lot of formaldehyde in the market is actually water-soluble paint, not emulsion paint Some illegal manufacturers use inferior water-soluble paint to fake emulsion paint Therefore, it is an effective way to prevent pollution to choose positive cargo and keep ventilation (3) The basic performance of exterior wall emulsion paint is similar to that of interior wall emulsion paint, but the paint film is hard and the water resistance is stronger Emulsion paint for exterior wall is generally used for exterior wall, and it can also be used in toilet and other places with high humidity Of course, the exterior wall latex paint can be used internally, but do not use the interior wall latex paint externally (4) Fire retardant paint is a kind of fire retardant paint which is made of film-forming agent, flame retardant, foaming agent and other materials At present, a large number of inflammable materials such as wood and cloth are used, so fire prevention is a topic worthy of mentioning Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
