Description
Technical field
The present invention relates to building material technical field, in particular to a kind of semidry method Ardealite block and its processing technology.
Background technique
In the numerous utilization ways of ardealite, only building resource is only the best way for realizing that ardealite largely utilizes
Diameter.Ardealite building resourceization is not only big to the consumption amount of ardealite, and no new pollutant generates, and can also reach energy conservation, section
The useless purpose of soil, benefit, helps to solve ardealite pollution problem.Presently commercially available Ardealite block water absorption rate 30% or so,
And major part is only used for inner wall of building, since its big water absorption rate and application range are narrow, strongly limits Ardealite block
Using.Therefore preparation intensity is high, and low water absorption, the Ardealite block of simple production process will greatly improve the utilization of ardealite
Rate.
Summary of the invention
It is raw to solve existing Ardealite block the invention is intended to provide a kind of semidry method Ardealite block and its processing technology
Water paste ratio is very high during production, and intensity is low, the problem that arid cycle is grown.
One of this programme semidry method Ardealite block and its processing technology, including raw material and its parts by weight be：
950~1000 parts of phosphogypsum powder, 3~8 parts of hydrogen fluoride auxiliary agent, 1~5 part of water-reducing agent, 1~5 part of dispersing agent, 3~8 parts of retarder and
3~8 parts of reinforcing agent.
The beneficial effect of this programme：Water-reducing agent plays the role of enhancing mobility and lubrication；Dispersing agent can increase degranulation
Ability reduces time and energy required for completing dispersion process, after ardealite adds water mix, since ardealite granulin molecule draws
The effect of power, makes ardealite starch to form flocculent structure, is wrapped in 10%~30% mixing water among ardealite particle, no
Free-flowing and lubricating action can be participated in, to affect the mobility of concrete mix；Since diminishing agent molecule can orient
It is adsorbed in ardealite particle surface, makes ardealite particle surface with same charge (usually negative electrical charge), forms electrostatic row
Reprimand effect, promotes ardealite particle mutually to disperse, and flocculent structure is destroyed, and releases by wrapping portion water, flowing is participated in, to have
Effect ground increases the mobility of concrete mix；Retarder reduces ardealite hydration rate and aquation heat, extends setting time；
The setting rate and gain in strength rate of reinforcing agent adjustable concrete at different temperatures；Hydrogen fluoride auxiliary agent can assist above-mentioned object
Matter gives full play to effectiveness, and reduces the usage amount of mentioned component, reduces mixing time, and rosemary can reduce in air bacterium and micro-
Biology, the cilium of Caladium bicolor can adsorb the dust particle in air, effectively purification air, moreover it is possible to increase humidity, sterilizing；Rosemary
With Caladium bicolor can reduce ardealite stirring when dust fly upward and mixture in bacterial component.
Further, the raw material further includes：Rosemary and Caladium bicolor, parts by weight are：1~5 part of rosemary and floral leaf
1~5 part of taro.Rosemary can reduce bacterium and microorganism in air, and the cilium of Caladium bicolor can adsorb the dust particle in air, have
Effect purification air, moreover it is possible to increase humidity, sterilizing；Dust flying upward and mixing when rosemary and Caladium bicolor can reduce ardealite stirring
Close bacterial component in object.
Further, each raw material and its parts by weight are：960 parts of phosphogypsum powder, 4 parts of hydrogen fluoride auxiliary agent, water-reducing agent 5
Part, 1 part of dispersing agent, 3 parts of retarder, 8 parts of reinforcing agent, 2 parts of rosemary and 2 parts of Caladium bicolor.Less fluorine is added into phosphogypsum powder
Change hydrogen auxiliary agent, needs to be added more water-reducing agents and reinforcing agent increases mixture mobility, while reducing dispersing agent and slow setting
The addition of agent prevents mixture rapid condensation.
Further, each raw material and its parts by weight are：980 parts of phosphogypsum powder, 6 parts of hydrogen fluoride auxiliary agent, water-reducing agent 4
Part, 2 parts of dispersing agent, 5 parts of retarder, 7 parts of reinforcing agent, 3 parts of rosemary and 3 parts of Caladium bicolor.Appropriate fluorine is added into phosphogypsum powder
Change hydrogen auxiliary agent, the addition for reducing water-reducing agent can reduce the mobility of mixture.
Further, each raw material and its parts by weight are：1000 parts of phosphogypsum powder, 8 parts of hydrogen fluoride auxiliary agent, water-reducing agent 2
Part, 4 parts of dispersing agent, 6 parts of retarder, 3 parts of reinforcing agent, 5 parts of rosemary and 5 parts of Caladium bicolor.It is added into phosphogypsum powder compared with polyfluoro
The usage amount of other compositions can be reduced by changing hydrogen auxiliary agent, can also reduce mixing time.
Further, a kind of processing technology of semidry method Ardealite block includes the following steps：
(1) prepare raw material：Prepare raw material by above-mentioned parts by weight；
(2) Raw material processing：To be added after phosphogypsum powder and hydrogen fluoride auxiliary agent and dispersant phosphogypsum powder weight 30~
36% water is stood 5~8 minutes, sequentially adds water-reducing agent, retarder, reinforcing agent, rosemary and Caladium bicolor later, will
It is put into forced stirrer, stirs 30~60 seconds, obtains mixture；
(3) transfer formation：Said mixture is sent into molding machine, until its molding obtains semidry method Ardealite block.
First water will be added after phosphogypsum powder and hydrogen fluoride auxiliary agent and dispersant, hydrogen fluoride auxiliary agent can reduce the use of water
Amount, while dispersing agent is first added and can avoid forming flocculent structure after phosphogypsum powder is directly mixed with water, it is stood, can make to disperse
Agent gives full play to effectiveness, adds water-reducing agent, retarder and reinforcing agent later under the action of hydrogen fluoride auxiliary agent, can reduce diminishing
Agent, retarder and reinforcing agent dosage.
Further, before rosemary and Caladium bicolor being added, by rosemary and Caladium bicolor, it, which is put into salt water, impregnates 2 hours, dries in the air
It is dry, by slag it is mixed after with abrasive wheel be ground to 30~50 microns.Impregnating in salt water can sterilize, and dry and be convenient for after immersion
Blend, mixed later with slag, waste material utilization is carried out to slag, slag can increase the intensity of ardealite, with rosemary and
Caladium bicolor blends simultaneously can increase coefficient of friction, and reduction blends the time, and increase blends area.
Further, the water-reducing agent is polycarboxylate high performance water-reducing agent.Polycarboxylate high performance water-reducing agent is to cement etc.
Many powder body material peptizaitons are good, and cost performance is higher.
