For more than a hundred years since the color cement tile entered China, the manufacturing process is gradually improved and improved. The color cement tile paint and oily cement tile paint can be constructed by means of air spraying, airless spraying, brushing and so on.
According to the development path of the painting process of cement tile manufacturers, the water-based paint requires good atomization effect of the spray gun, that is, the air pressure of the air compressor is large and the amount of paint is small. Water based color tile paint cannot be sprayed on wet tiles. Peeling and peeling are strictly prohibited in the wet environment, otherwise peeling and peeling will occur in the rainy day. In water, rain and humid environment, the coating is easier to peel off. When air spraying is adopted, the air of the air compressor shall be set within the range of 6-8kg, and the spray gun shall be cleaned with clean water to ensure that there is no oil stain and other sundries in the gun, which can be sprayed after drying. It is forbidden to clean the water-based paint spray gun with oily paint cleaner. When spraying wet coating, pay attention to control the spraying amount and nozzle angle. The water content of concrete should be adjusted as much as possible. The water on the surface of tile should be free of water stains, which can be dehumidified by blowing properly.
The sprayed tiles can be stacked after being placed in a ventilated and dry place until the surface is dry, but they need to be handled with care to prevent scratches. The tiles can be watered and cured after three to seven days (extended appropriately in winter). The oil paint can be used after opening the barrel, stirring slightly and adding diluent; The water-based paint must be stirred evenly before use, and it is strictly prohibited to add any substance. For 72 hour film stripping spraying, it shall be noted that there shall be no water stains and other dirt, the surface shall be dry, and the construction shall not be carried out in high humidity and temperature environment.
