Common knowledge of coatings: what are the new developments of construction tools for architectural coatings

Core tip: the development of construction tools for architectural coatings is reflected in the following aspects (1) The rapid increase of roller types can reflect the development of construction coating tools The roller used to be used for coating construction is monotonous in variety and single in function, but now there are many kinds of roller put into application, including all kinds of pattern roughing roller, decoration machine printing roller, embossing roller, foaming roller, striped roller, plastic sheet roller with strong decorative texture and rubber roller with pulled pattern, etc., which can be used to construct different decorative effects and qualities Sensitive coating, large 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 Home of coatings: the development of construction tools of architectural coatings is reflected in the following aspects (1) The rapid increase of roller types can reflect the development of construction coating tools The roller used to be used for coating construction is monotonous in variety and single in function, but now there are many kinds of roller put into application, including all kinds of pattern roughing roller, decoration machine printing roller, embossing roller, foaming roller, striped roller, plastic sheet roller with strong decorative texture and rubber roller with pulled pattern, etc., which can be used to construct different decorative effects and qualities Sense of the coating, greatly enriching the decorative style of the paint (2) Spraying construction machinery high pressure airless spraying is a new construction method gradually applied in recent years This kind of machinery has high spraying efficiency and the quality of coating can be guaranteed The principle of high pressure airless spraying is totally different from that of traditional air spraying The traditional air spraying is to use the negative pressure generated by the high-speed air flow formed by the compressed air at the exit of the spray gun to bring out the coating, and blow the coating into particles to reach the spraying surface Due to the mixture of compressed air in the coating, the coating particles fly and diffuse to the atmosphere In addition to the volatilization of solvent, more spray coating particles are formed, which not only wastes a lot of coating, but also worsens the working environment High pressure airless spraying is to use compressed air to spray paint During spraying, the paint shall be pressurized to a pressure of 10-40mpa with a high-pressure pump, and then sprayed through the nozzle of the spray gun When the coating under high pressure leaves the nozzle and reaches the atmosphere, it expands rapidly and atomizes into fine particles due to the sudden release of pressure When spraying, only use compressed air to drive high-pressure pump to pressurize the coating The compressed air is not in direct contact with the paint Therefore, there is no compressed air in the sprayed coating stream, so there is no mixture of coating and air, and there is less foggy coating flying to the atmosphere Compared with ordinary air spraying, high-pressure airless spraying has less environmental pollution, significantly improved labor conditions, and reduced the loss of coating in spraying construction At present, airless spraying machinery is developing rapidly, and it is developing towards the direction of intelligent operation, diversified models, simplified use and reliable quality Some imported airless spraying machinery abroad often has these functions Job intelligence refers to the microprocessor installed in some spraying machines, which can track important work details and display them on the display screen of easy to distinguish LED (large electronic display) It can clearly understand the details of spraying operation, such as spraying material consumption, spraying form (High-Yield spraying or fine finishing spraying), etc., and can automatically return flow cleaning, and can remove the filter slag and automatic diagnosis and removal of faults without dismantling machinery Model diversification refers to different models of sprayers suitable for spraying the same type of coating, for different power conditions, such as hydraulic powered, gasoline powered and electric powered At the same time, there are different models for different engineering situations, such as the models applicable to super large residential buildings, super large commercial buildings and super large industrial buildings, the models applicable to large residential buildings, large commercial buildings and large industrial buildings, the models applicable to medium-sized projects, and the models applicable to small projects Simplicity of use means that the spraying machine itself has the functions of coating filtration, automatic cleaning, and the disassembly, installation and configuration of the nozzle and other parts are convenient and quick, as well as the slide rail frame, retractable handle, etc., which make the spraying operation convenient and labor-saving Quality reliability refers to uniform spraying, high quality of the obtained coating film, solvent corrosion resistance of the machine, resistance to over spraying, flushing and harsh construction environment, etc., and can ensure a long service life of the machine (3) In recent years, the application of construction auxiliary machinery -- electric hanging basket is also an important development of construction coating technology This method can solve the problem that the construction period of the new project is relatively tight and the removal speed of the external scaffold is relatively fast, but it can not meet the humidity requirements of the coating construction for the base layer, so that the external scaffold can not wait for the base layer to dry, and the time of the scaffold occupation is less splashed The use of basket construction can make better use of advanced construction machines and tools such as airless high-pressure spraying and coating methods, and can improve the construction quality, save labor and materials At the same time, some coating processes are easy to produce joint and color difference when using external scaffold construction, such as spraying multiple layer coating, real stone paint and imitation resin curtain wall effect coating, etc This is because, when spraying on the external scaffold, one is the adverse effect of the distance between the horizontal pole of the external scaffold and the wall on the spraying operation (so that the spray gun can't keep the same angle and distance with the spraying surface all the time), and it's easy to have a joint; the other is that a large surface is divided into multiple construction from top to bottom, which inevitably results in new and old color differences and joints; the third is when spraying on the external scaffold It is difficult to find the construction joint and color difference due to poor light due to the shielding of safety net Only after the spraying is completed and the scaffold is removed can the problem be found It is easy to solve these problems by using the construction of the hanging basket, because the hanging basket can be sprayed successfully in each process from top to bottom, without cross contamination, and the construction time line is sufficient, the defects are clear at a glance, easy to control, and the coating effect is uniform from top to bottom For the renovation and coating of old walls of high-rise buildings, the cost of scaffolding is high, and it affects the normal use of buildings, especially for hotels, shopping malls and other business buildings, the use of hanging basket construction reduces the renovation cost and reduces interference, without interruption of business Home of coatings is
