Coating knowledge: coating knowledge: brief introduction of four construction methods of marine coating

Core tip: ship coating construction method: roll coating method this kind of coating construction method refers to painting after roller is covered with paint The roller shall not be stained with too much paint The principle is that the paint shall not spill over both sides of the roller When painting, the roller shall not roll too fast The roller shall roll up, down, left and right slowly Special attention shall be paid to rough surfaces and welds The corners shall be repaired with paint brush The roll coating method has high efficiency and can be used in large area painting, but the roll coating method can not be used for quick drying coating Ship coating construction method: brush painting method, as the name implies, refers to the staggered vertical and horizontal painting on the surface of components with paint brush Brush coating has strong penetration, which can make the coating penetrate into the pores and gaps 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 Coating home news: ship coating construction method: roll coating method this kind of coating construction method refers to painting after the roller is covered with paint The roller shall not be stained with too much paint The principle is that the paint shall not spill over both sides of the roller When painting, the roller shall not roll too fast The roller shall roll up, down, left and right slowly Special attention shall be paid to rough surfaces and welds The corners shall be repaired with paint brush The roll coating method has high efficiency and can be used in large area painting, but the roll coating method can not be used for quick drying coating Ship coating construction method: brush painting method, as the name implies, refers to the staggered vertical and horizontal painting on the surface of components with paint brush Brush coating has a strong penetration, which can make the coating penetrate into the pores and cracks When there is moisture on the steel plate surface, brush coating can squeeze out the moisture, so that the coating really adheres to the components In addition, brush coating also saves the coating However, the efficiency of brush coating method is low, which is only used in small area, corner and some places Construction method of marine coating: airless spraying, a high-tech coating construction method, refers to spraying the coating with high pressure, and the coating is forced to atomize at the nozzle outlet to form a paint film on the surface of the coating Compared with spray method, airless spray method is more suitable for large area construction because of its less dispersion, high efficiency and thick film However, when airless spraying is used, the technical requirements for manual work are high, and attention should also be paid to fire prevention At present, almost all shipyards use this method when painting large areas Ship coating construction method: spraying method is to use compressed air with a pressure of 3-5pa to atomize the coating and spray it on the surface of the coating to form a paint film During spraying, the nozzle shall be vertical to the surface to be coated, and shall move up and down in parallel without swinging When using spray method, pay special attention to keep the coated surface clean and dry, otherwise the adhesion of the paint will be reduced, the paint flying and solvent volatilization caused by compressed air are many, pay special attention to sparks The spraying method has high efficiency and is suitable for large-area painting, but the paint flying causes part of the paint loss No matter which coating construction method is used to construct the ship surface coating, we should pay attention to the double factors of construction quality and cost saving But at present, large shipyard will adopt airless spraying method in the surface coating construction, which not only has high working efficiency, but also is not easy to cause the loss of coating [focus on WeChat official account "paint net"; pay attention to surprises, scan code to see if your husband is selling paint..
