Many details are stated.It may be evident, however, that these embodiments can also be realized in the case where not having these details.
In other examples, for the ease of describing one or more embodiments, known structure and equipment are illustrated in block form an.
For above-mentioned resins synthesis filter pressing garbage, the present invention provides a kind of process is simple, stable, practical diatom
Native cake recycles technology.
Due to resins synthesis filter pressing garbage --- the kieselguhr content in kieselguhr cake is very high, but garbage kieselguhr cake
It is complicated paste semisolid mixture.It is unrealistic that its each component is kept completely separate, is purified, also it is not necessary that.This
It is bright by the step process such as diluted alkaline saponification, point water are carried out to synthetic resin filter pressing garbage kieselguhr cake, obtain resin soap mixing
Then this resin soap mixed liquor is applied to bitumen varinishes are made in asphaltic liquid by liquid, to reach the mesh of twice laid, potentiation of guaranteeing the quality
's.
Fig. 1 shows the recovery and treatment method flow process of resins synthesis filter pressing garbage according to embodiments of the present invention.Such as Fig. 1
It is shown, the present invention provide resins synthesis filter pressing garbage recovery and treatment method mainly including resin soap mixed liquor preparation and
Two steps of application of resin soap mixed liquor.
Specifically, during step S100 prepares resin soap mixed liquor, first by resins synthesis filter pressing garbage,
In 10%NaOH aqueous solutions input saponification pond, under 50 DEG C of stirrings, saponification process is detected without micelle to resin soap；Then in saponification pond
Middle addition 10%HCl aqueous solutions, adjust PH=8-9, stand, divide water, obtain resin soap mixed liquor.
Wherein, the percentage by weight for putting into the composition in the saponification pond is respectively：Resins synthesis filter pressing garbage：45～
55%, 10%NaOH aqueous solution：40～50%, 10%HCl aqueous solution：5～10%.
In the application process of step S200 resin soap mixed liquor, mainly use asphaltic liquid and process the resin soap for preparing
Mixed liquor.Firstly the need of preparing asphaltic liquid：Asphalt, 200# solvent naphthas are entered into kettle and is warming up to 120 ± 5 DEG C of fusings, stirring is equal
Even, cooling takes the dish out of the pot and can obtain the asphaltic liquid of needs.Then the resin soap mixed liquor for preparing is added under asphaltic liquid stirring, grind
Mill is dispersed to fineness and is not more than 60 microns, by adjusting viscosity and filtration, bitumen varinishes is obtained.
Wherein, to be 40～50%, the resin soap is mixed the percentage by weight of the asphalt, 200# solvent naphthas
The percentage by weight for closing liquid is 10～20%.
In above-mentioned recycling flow process, the NaOH that adopted, HCl, asphalt, 200# solvent naphthas belong to general industry
Product, resin soap mixed liquor belong to own product.
Garbage silicon can be seen that by the recovery and treatment method of the resins synthesis filter pressing garbage shown in above-described embodiment
Resin micelle composition Jing saponification in diatomaceous earth cake generates resin soap, and the property with obvious surfactant is not only stabilized
Originally the kieselguhr powder body being adsorbed in, and create the emulsifying activity group to raw material added by subsequent handling.And Jing processes life
Into resin soap belong to organic polymer, be applied to subsequent handling as surfactant.
During the resin soap mixed liquor prepared using asphaltic liquid process, choosing multiple dispersing apparatus, most end form
Into superfine Water-In-Oil emulsification system, there is no system breakdown of emulsion, while increased the repulsive force between microgranule, enhance non-
The thixotropy of Newton type fluid, and then improve the storage stability of system.
