Plaster line is a decorative moulding of a building made of plaster. It has fireproof, moisture-proof, heat preservation, sound insulation, heat preservation, and has a good decorative effect. However, when painting gypsum slurry, due to the raw material itself and improper operation, mottled potholes or small pores appear on the surface of the dried gypsum line, which are caused by the gas in the gypsum slurry not being discharged in time. Therefore, it is recommended that gypsum line defoamers can be used to solve such problems!Let's find out!
The hardness and whiteness of gypsum powder produced by different manufacturers will vary, so the probability of causing air bubbles will also vary. And these things are determined by the raw materials used by the manufacturer, and we have no way to control it as a purchaser. The gypsum line defoamer can be used before and after the slurry foams, and the addition before foaming can play a long-term role in foaming, and the foam can be quickly eliminated for the slurry that has been foamed. Therefore, a gypsum line defoamer can be used to avoid the occurrence of bubbles.
In the process of mixing gypsum powder, if the temperature of the water is too high, or the speed of stirring is too fast, it will cause bubbles. The surface tension of the defoamer for gypsum line is small, the surface activity is high, the defoaming effect is good, and the stability is good. It can effectively suppress the formation of foam and improve the flow and stability of fluids. The defoamer for gypsum line has little effect on the stability of cement, and has no adverse effect on the properties of cement substrate. The amount of defoamer used in the gypsum line should be adjusted appropriately according to the specific situation during use. The usual dose added is 01-0.3%。A special defoamer is added to the gypsum and stirred thoroughly using a stirring device, etc.
The main component of the defoamer for gypsum line developed by the defoamer manufacturer is silicone. It has a significant defoaming and antifoaming effect on gypsum foam, strong alkali resistance, high temperature resistance, and can remain stable in the face of complex construction environment, and is not easy to foam twice. With the help of gypsum line defoamer, your gypsum slurry will glow with a new brilliance, better meet the needs of stucco leveling and gypsum line production in indoor walls and other places, and say goodbye to hollow cracks and mottled holes
