When technique, in dusty material, gypsum powder and polymer powder are according to the proportioning of certain particle diameter, by powder
The profiled member that powder material and ink-jet glue prepare out, its 1h, 2h, 24h comprcssive strength is the most relatively
Height, it also be excellent for adding its water resistance of wetting agent in embodiment, after addition brightening agent, finished parts white
Degree improves further.And intensity is relatively low in comparative example, resistance to water is the most poor, and whiteness is bad, is unfavorable for
Later stage processes.Illustrate to use the dusty material in the embodiment of the present invention and the raw material of ink-jet glue, proportioning
And technique, dusty material and ink-jet glue are prepared profiled member, intensity can be obtained higher, resistance to
The more preferable finished product of aqueous.
In sum, the compositions of the embodiment of the present invention and compositions processing technology can obtain high intensity,
The profiled member of water-tolerant.
