Water removal of medium temperature wax and precision wax casting: if the steam water remover has good water removal effect, it only takes 3 hours to remove water. The set temperature of the water removal bucket is 120 ℃, the actual wax material temperature is about 100 ℃, and the water removal time is 8 hours.




Answer: Medium temperature wax and precision casting wax are polymer compounds based on rosin resin. It is insoluble with water, that is to say, it will not react with water chemically, and it is usually formed by mixing physical factors in water. When the wax water is heated by the mixed liquid, the water will be partially gasified, and the wax and water will be mixed more evenly. When the temperature drops, the wax and water will separate due to the density.




In other words, as long as there is wax in the water, when the temperature drops, the wax will drop from the water, and the wax will be separated from the water. As long as there is wax in water, there is much.




The reason why the wax water content in the wax ejector is very high has nothing to do with the dewaxing kettle, but is related to the temperature setting of the bucket, the high temperature time set by the bucket, the temperature drop of wax and water, and the time. In addition to the cleanliness of the bucket drain. Medium temperature wax and precision casting wax are hydrocarbons and amorphous substances. Solid is easy to separate from water, while paste is not easy to separate from water.
