Paint knowledge what is the construction technology of crack paint

Core tip: the development of science and technology has led to the renovation of various equipment and materials, the improvement of people's living standards, the continuous improvement of people's requirements for building and decoration, and more and more materials are used in decoration Crack paint is also quietly rising in the decoration industry Because it can form good-looking cracks, it can protect and decorate the surface of objects, and improve the added value of products, so it is widely welcomed by people The following small series will introduce what is crack paint and the construction technology of crack paint What is crack paint: the crack paint process is to spray the crack finish paint which is obviously different from the primer color on the surface of the coated object, when the crack Shenyang steel structure fireproof coating construction expert punde Building Fire Engineering Co., Ltd Recommended introduction: since its establishment, Shenyang punde Construction Fire Engineering Co., Ltd has cultivated a group of professional construction teams with excellent equipment, rich experience and serious responsibility with advanced and scientific management methods and strict engineering quality assurance and after-sales service system It has undertaken a number of fire system installation projects, which has been praised by customers Every idea and special requirement of you will be fully considered by us and fully realized in the construction technology, which will become the cornerstone of our successful long-term development We are looking forward to your invitation, to provide you with quality services and high-quality technical support! All construction coatings have passed ISO9001 Paint Home News: the development of science and technology has led to the renovation of various equipment and materials, the improvement of people's living standards, people's requirements for building and decoration are also constantly improving, more and more materials are used in decoration Crack paint is also quietly rising in the decoration industry Because it can form good-looking cracks, it can protect and decorate the surface of objects, and improve the added value of products, so it is widely welcomed by people The following small series will introduce what is crack paint and the construction technology of crack paint What is crack paint: the crack paint process is to spray the crack finish paint which is obviously different from the primer color on the surface of the object to be coated When the crack finish paint film is formed, due to the rapid volatilization of the solvent, the inside of the paint film will produce wide cracks due to volume shrinkage At this time, the crack finish paint is in the film There are irregular crack gaps on the surface, so that the underlying color different from the crack finish color is exposed in the crack gap, thus forming the beautiful crazing pattern we need Characteristics of crackle paint: crackle paint is a kind of nitrocellulose crackle paint which can be made of nitrocellulose, pigment, physical pigment, organic solvent, auxiliary agent and other abrasives It also has some basic characteristics of nitrocellulose paint, belonging to volatile self drying paint, without adding curing agent and fast drying speed Therefore, the crack paint must be in the same characteristics of one or more layers of nitrolacquer surface to fully integrate and show another crack characteristics of crack paint Due to the high content of crack paint powder and volatile solvent, it has large shrinkage and small flexibility After spraying, the internal stress produces high pulling strength, forming a good and uniform crack pattern, enhancing the beauty of the coating surface and improving the decoration Construction process of crack paint: 1 Take crack paint as single component paint, no other curing agent is required when paint is prepared, and the construction viscosity can be adjusted by appropriate amount of special crack water produced by the same factory, so as to facilitate construction After fully mixing the adjusted crack paint, use 100-200 mesh filter screen to filter, and then construction can be carried out The paint liquid is now prepared and used Once it is prepared, try to use it up to 4 hours within 2 hours After the paint is opened, it must be sealed immediately to avoid volatilization, moisture absorption deterioration and affecting the use effect 2 In general, the spraying construction effect is the best, the crack texture is round and natural, uniform and three-dimensional; if the hand brush construction is used, the crack will be affected by the uneven change of gesture and direction when painting, resulting in the feeling of uneven crack texture, dry and rigid 3 Generally, the primer shall be applied before the preparation of the construction crack paint The primer can be matched with the crack primer produced by the same factory or colored with aluminum powder, pearlescent powder, gold powder, etc Generally speaking, the greater the color contrast between the primer and the top coat, the stronger the stereoscopic sense and the better the effect But if it is applied on polystyrene plastic (PS), it can be directly sprayed with crack paint without priming The above is the introduction of crack paint I hope that through the introduction of the above content, it will be helpful for you to understand and understand crack paint 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,
