The authors put forward a theory of "four-stages"in mature period of preserved eggs, i.e. hydrade stage, solidifying stage, basic mature stage and afterripening stage.
Radioactive nuclides are solidified at crystal lattice as one part of crystalloid by zirconolite-rich synroc, which greatly enhances the long-term safety of radioactive waste disposing.
A foamable phenolic resin was prepared,through addition,condensation,in the presence of alkali.The resin was foamed with surfactant, foamer,solidifying agent , then the foam phenolplast was given .
The pastille system is consisted of rotoformer and cooler. The rotofomer drop the liquid on the belt evenly and the drop solidified as the belt is moving forward continuously.
In ultrasonic field, authors studied solidify of water base epoxy dope and suspend and decentralization of millicron grain in water base epoxy resin, developed a series of water base dope.
