Medium temperature wax and precision casting wax water removal problem: the set temperature of the water removal bucket is 120, the actual wax temperature is about 100 degrees, the water removal time is 8 hours, if the steam water eliminator water removal effect is good, it only takes 3 hours to remove water.
A: Medium temperature wax and precision casting wax are a kind of rosin resin-based polymer compound. It is immiscible with water, that is, it does not chemically react with water, usually it is only mixed in water due to physical factors. When the wax-water mixture is heated, the water vaporizes a part, and the wax is further mixed with the water evenly. Precision casting wax medium temperature wax AT996 When the temperature drops, the wax and water will separate due to the density.
That is to say, no matter what state of water it is, 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 components, just how much.
Why is the wax water content of the wax injection machine very high, this has nothing to do with the dewaxing kettle, but has a relationship with the temperature setting of the water removal bucket, and has a relationship with the high temperature time set by the water removal bucket, and the wax has a relationship with the temperature drop and time of the water. There is also a relationship between the cleanliness of the drainage of the removal bucket. Medium temperature waxes and precision casting waxes are hydrocarbons and also amorphous substances. It is easy to separate from water in solid state and not easy to separate from water in paste.
