Dewatering of medium temperature wax and fine casting wax: the setting temperature of the dewatering bucket is 120 ° C, the practical wax material temperature is about 100 ° C, and the dewatering time is 8 hours. Assuming that the steam water remover has good dewatering effect, it only takes 3 hours to dewater.




Answer: Medium temperature wax and fine casting wax are polymer compounds based on rosin resin. It is not miscible with water, which means that it does not react with water chemically. Generally, it is mixed in water only because of physical elements. When the wax water mixture is heated, part of the water vaporizes, and the wax and water are further mixed evenly. When the temperature of fine casting wax and medium temperature wax decreases, the wax and water will be separated due to the density.




It can also be said that no matter the water in that state, as long as there is wax in the water, when the temperature drops, the wax will be separated from the water. As long as the water dewaxed from the steam kettle contains wax, it just counts.




The reason why the wax water content of the wax ejector is high is that it has no connection with the dewaxing kettle, but with the temperature setting of the dewatering bucket, the high temperature setting of the dewatering bucket, and the drop in the temperature of wax and water. There is also a connection between the cleanliness of the drainage of the dewatering bucket. Medium temperature wax and fine casting wax are hydrocarbons and non crystalline substances. It is easy to separate from water in solid state, but not easy to separate from water in paste
