| 配制方法： |
The Water is heated to 70C, and held there with agitation. the white olein, ammonia, isopropanol and "Acrawax" C powdered are now added in that order as rapidly as possible, agitating enough to get efficient dispersion without forming excessive foam. As soon as all the ingredients have been added, the kettle cover is put on to prevent loss of volatiles and the batch is cooled to 50C with continued agitation to give a smooth consistency. A paddle is used to mix in any powder clinging to the sides of the kettle.
The material is unloaded carefully, so as to minimize foam, into open head unlined steel drums through several layers of cheesecloth and allowed to stand for at least one day.
Any crust or foam which remains on the surface is subsequently skimmed off.** *Dispersion may be made with "Acrawax" C Atomized by first wetting down the wax with some of the isopropanol.
**If the dispersion is insufficiently stable, it can usually be improved by the addition of more ammonia. |
