Problems easy to appear in winter construction of real stone paint sprayer
In the winter construction, the temperature difference between morning and evening is large at this time, and sometimes the temperature during the day matches the construction temperature, but it will drop below zero at night, and there will be cold and humid weather conditions. In this climatic condition, spraying with a real stone paint sprayer may affect the quality of the application. The following editors will introduce the prone problems in the construction of real stone paint spraying machines in winter.
1. The real stone paint spraying machine is constructed by air pump, and the air jet is sprayed. Due to the cold weather, the air flow will be blocked, the nozzle will be blocked, the spray will not come out and the nozzle discharge will not be smooth, and the phenomenon of uneven spray paint surface will be formed.
2. The thickness of real stone paint sprayed by real stone paint spraying machine is 3-5mm. The drying cycle is long. At 25C and humidity is less than 85%, it takes more than 24 hours to dry completely. In winter, the night temperature is low, although antifreeze Agent, freezing will still occur, and the drying time will be longer.
3. After the construction of the real stone paint sprayer, in the cold weather of winter, the real stone paint will freeze in a low temperature environment, and the temperature will rise and melt. The emulsion in the real stone paint will be difficult to form a film, and even the emulsion will lose its effectiveness, causing the paint Membrane coating returns to alkali, flakes or even falls off, and the construction quality cannot be guaranteed.
The above are some questions about the easy construction of real stone paint sprayer in winter. In addition, we should pay attention to the weather and temperature conditions of coating products, especially thick products such as real stone paint. Although some manufacturers have adopted measures such as adding antifreeze and increasing the amount of film-forming aids from the product formula, due to the true stone paint products Features, there are still some unavoidable problems, which will bring many disadvantages and hidden dangers to the construction and quality of real stone paint under low temperature conditions, and may cause quality problems.
