    Core tip: with the coating, there must be a coating process With a coating process, there must be a second or third coating process For water-based wood paint, the seven painting methods we know are introduced to you, hoping to help you: First, brush Originated from the ancient construction method, wool brush is generally used This method is widely used in interior decoration The utility model can save paint, and the construction is simple, the tool is simple, the utility model is easy to master, the flexibility is strong, and the application range is wide Second, roll coating It is a rolling coating on the surface of the workpiece by using the coating dipped in the roller 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: with paint, there must be painting process With a painting process, there must be a second or third painting process For water-based wood paint, at present, we will introduce the seven major painting methods to you, hoping to help you: first, brush Originated from the ancient construction method, wool brush is generally used This method is widely used in interior decoration The utility model can save paint, and has the advantages of simple construction, simple tools, easy to master, strong flexibility and wide application range Second, roll coating It is a coating method of rolling on the surface of the workpiece by using the coating dipped in the roller Generally, it can be divided into manual roller coating and machine roller coating, which is suitable for the coating of plane workpiece It has the advantages of less paint waste, not easy to form paint dust, good environmental protection and high work efficiency Third, air spraying Spraying is a kind of coating method which uses compressed air or other means as power to spray the coating from the spray nozzle of the spray gun and form a uniform coating film in the form of fog like dispersion deposition It has the advantages of simple and cheap construction equipment, high construction efficiency, high film quality, and can be applied to complex shape objects Fourth, airless spraying Airless spraying is also called high-pressure airless spraying It is also a kind of painting method that uses compressed air or electric power as the power to drive the hydraulic pump to directly pressurize the paint Through the high-pressure hose, spray gun and nozzle, the paint will be sprayed out in an instant, forming a very fine fan-shaped mist like paint liquid, and quickly spraying to the surface of the painted object to form a paint film The main advantages are: high paint utilization rate, high work efficiency, direct spraying of high solid content, high viscosity paint, good film quality (only slightly worse than air spraying), no need to add additional diluent, cost saving, conducive to environmental protection Fifth, scraping (batch coating) Scraping is a commonly used construction method in the construction of high viscosity coatings It is a way of thick film coating of viscous coatings by using metal or non-metal scraper The advantages are simple construction method and thick one-time coating Sixth, dip coating (the sealing primer is common) for a certain period of time, so that the coating can directly penetrate into the coated object to achieve the purpose of coating The advantages are strong permeability and simple construction method Seventh, mixed air spraying Mixed air spraying, also known as medium pressure mixed air spraying, is a kind of coating method that uses compressed air or electric power as power to drive plunger pump to directly pressurize the paint, and then spray it out through the feeding hose, spray gun and nozzle in an instant to form a very fine mist like paint liquid and quickly spray it to the surface of the coated object to form a paint film The advantages are basically the same as high-pressure airless spraying The only difference is that this coating method mixes certain air into the coating, optimizes the atomization effect, and the spraying paint mist will be more uniform The above seven painting methods can be selected and judged according to the actual situation Of course, there must be some small shortcomings 1 Disadvantages of brush coating: high labor intensity, low production efficiency, not suitable for fast drying and poor leveling coating, and easy to leave brush marks, sagging and uneven film thickness, affecting the smoothness and beauty of the coating 2 Disadvantages of roller coating: the surface effect of the paint film is slightly poor, the coating equipment is expensive, the scope of application is small, and it is only suitable for the workpiece of the coating plane 3 Disadvantages of air spraying: low paint utilization, high consumption, easy to form paint dust pollution, poor environmental protection performance, etc 4 Disadvantages of airless spraying: the spraying equipment is a little expensive, the performance requirements of the coating are high, thick coating is easy to bubble, etc 5 The disadvantages of scraping are: low working efficiency, single applicable coating system, only suitable for high consistency coating, simple shape of coated objects, etc 6 The disadvantages of dip coating are: it is unable to achieve a relatively thick film, easy to produce sagging phenomenon, etc 7 The disadvantages of mixed air spraying are the same as airless spraying, the spraying equipment is slightly expensive, the coating performance requirements are high, thick coating is easy to bubble, etc 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,
