Description
Technical field
The present invention relates to super absorbent resin powder processing technology field, particularly a kind of method of health material in air-flow crushing super absorbent resin epoxy-type concrete.
Background technology
At present, super absorbent resin (SAP) is as conserving material in concrete, both the contraction of concrete material can have been improved, later maintenance measure and the expenses such as watering, covering can be saved again, have important use value for the engineering field such as high performance concrete and mass concrete.Ultra-fine grain SAP powder (several microns to tens microns) to release completely in concrete after water the aperture in hole of boxing out be far smaller than the aperture of conventional SAP powder (100-200 μm), greatly can reduce the adverse effect that it causes early age strength of concrete loss.
Airflow pulverization method a kind ofly conventional prepares ultra-fine grain method at present, for low temperature is pulverized without medium, utilize the mutual collision between material, friction, shearing and pulverizing, material after pulverizing moves to graded region with ascending air under blower fan draft effect, grading wheel carries out classification process to the particle after pulverizing, fine powder qualified for granularity is separated from meal, enter cyclone separator and deduster collection, underproof meal drops to disintegrating area to be continued to pulverize, and by controlling clasfficiator, obtain the powder of different-grain diameter.This technique is simple, and cost of equipment maintenance is low, and noise is low, production process clean environment firendly, and the particle particle shape produced is good, narrow particle size distribution.
Mechanicalness pulverize be material many kinds of force such as repeated stock, friction, shearing between the Moving plate and price fixing of High Rotation Speed effect under pulverize, it is that a part of abrasive media (steel ball) carries out free falling campaign generation impulsive force in ball mill barrel that ball mill is pulverized, clash into the material in cylindrical shell, remainder abrasive media (steel ball) carries out rushing down motion and produces frictional force and material mixes along with the rotation of cylindrical shell is ceaselessly carried out colliding and grinding with material, cylindrical shell is in pivotal process, abrasive body also has landing phenomenon, in landing process, give material with abrasive action, super absorbent resin only can be processed into the particulate that particle diameter is hundreds of micron by above grinding mode, yield rate also only has about 60%, cause wastage of material significantly, and energy consumption is high, noise is large, equipment attrition lost efficacy fast.
Such as, Chinese invention patent ZL201210150346.0 discloses a kind of concrete inner curing agent, and the particle diameter after SAP adopts ball mill to pulverize reaches more than 600 orders; ZL201410816661.1 discloses a kind of concrete and strengthens conserving material and preparation method thereof in water conservation, and the SAP particle diameter after pulverizing with ball mill is 0.15 below ㎜; ZL201510032872.0 discloses the purposes of a kind of modified water absorbent resin as concrete antifreezing reinforcing material, and SAP is ground into the particle that particle diameter is not more than 120 μm in grinding machine.SAP size distribution disclosed in above patent is wide or particle diameter large, there will be the problem of concrete workability instability when casting concrete.
Therefore, in order to solve many deficiencies and the defect of above-mentioned prior art, be necessary the method studying health material in a kind of air-flow crushing super absorbent resin epoxy-type concrete.
