Paint common sense: discuss the construction characteristics and differences between plastic spray paint and spray paint

Core tip: spray coating (also known as spray ceramic coating, multi-layer pattern coating, relief coating, gorgeous spray brick, Bonn spray brick) is an aggregate building coating with organic polymer or organic materials and inorganic materials such as silica sol as the main film-forming materials Commonly used organic polymers include styrene acrylic emulsion, pure acrylic emulsion, epoxy acrylic emulsion, vinyl acetate ethylene copolymer emulsion, water emulsion epoxy resin and so on Rutile titanium dioxide, lithopone, zinc oxide, talcum powder, mica powder, quartz powder and fiber materials such as asbestos are commonly used in the mixed filler Varieties and dosage of additives Which is the price of Dajin diatom mud Recommended brief introduction: which is the price of Dajin diatom mud? How to buy genuine diatom mud? Guangdong diatom mud agent suggests placing a basin of cold water in the air conditioning room, so that the diatom mud wall can breathe effectively The feature of the breathing wall is obvious When the indoor air is dry, the diatom mud wall will release the absorbed water quickly Put it out to help regulate the indoor dry humidity It is suggested to place a basin of cold water in the air conditioning room, so that the wall of diatom mud can breathe effectively The feature of the wall that can breathe is obvious When the indoor air is relatively dry, the wall of diatom mud will absorb the water Paint Home News: spray paint (also known as spray porcelain paint, multi-layer pattern paint, relief paint, gorgeous spray brick, Bonn spray brick) is a kind of aggregate building paint with organic polymer or organic material and inorganic material such as silica sol as the main film-forming material Commonly used organic polymers include styrene acrylic emulsion, pure acrylic emulsion, epoxy acrylic emulsion, vinyl acetate ethylene copolymer emulsion, water emulsion epoxy resin and so on Rutile titanium dioxide, lithopone, zinc oxide, talcum powder, mica powder, quartz powder and fiber materials such as asbestos are commonly used in the mixed filler The type and amount of additives are determined by the base material According to the construction characteristics of the spray coating and the functions of different layers, the coating structure can be divided into three parts: (1) the primer (primer, primer) is the first coating applied on the base layer It penetrates the interior of the substrate, enhances the strength of the substrate, seals the surface of the substrate at the same time, eliminates the factors damaging the adhesion of the coating on the surface of the substrate, and increases the binding force between the skeleton and the substrate （2） The middle coat (middle coat, framework) is a special forming layer of spray paint, which is the main part of spray paint A special large caliber spray gun is used to spray on the base oil and then roll to form a full texture, novel and beautiful three-dimensional pattern The skeleton has enough bond strength and plays a reinforcing role in the building At the same time, the framework is the main part of the spray coating, which increases the durability, water resistance and strength of the spray coating （3） Surface oil (surface coating, finishing coat) surface oil is the surface layer of plastic spraying coating A variety of sun resistant color pigments are added to the surface oil, so that the spray coating has a soft color According to the different needs of indoor and outdoor, it can be sprayed into bright and flat coating The surface oil can beautify the surface of spray coating and improve the durability of coating Difference between spray painting and spray molding: ● spray painting is better than spray molding The molecular structure of solvents, auxiliaries and resins used for spray painting are of great help to leveling And spray molding does not, so often play orange effect ● paint can be repaired In the process of painting, the pockmarks or scratches caused by too large air film can be repaired at any time, because the paint has the function of repainting But spray molding is not good ● the flexibility (bending) of paint spraying is better than that of plastic spraying The paint can be bent 1mm or even T-bend, but the spray molding can't ● the painting is rich in decoration The appearance color of spray painting is dozens of times more than that of spray molding, and the same material can be made into different effects For example, plastic, wood, paper, cloth, leather and other non-metallic materials can be made into aluminum effect ● the hardness of paint spraying is the same as that of plastic spraying ● the pretreatment cost of spray molding is low and faster than that of spray molding ● spray molding must be baked at high temperature Plastic, wood, paper, cloth and leather cannot be baked at high temperature ● paint delivery is fast, even a small batch or special requirements can also maximize the satisfaction of customer orders ● compared with spray molding, the surface quality of spray painting is easier to overcome the defects of base material and meet the quality requirements of customers However, if the spray molding surface is not properly treated, it is easier to produce pockmarked defects (bubbles) 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,
