Abstract
The invention discloses a method for preparing gypsum binder from titanium gypsum and solves the problems of land occupation, resource waste, environmental pollution and the like in the prior art. The method is characterized in that the titanium gypsum is stirred and mixed uniformly with other raw materials and auxiliary materials, and the general type (G) gypsum binder meeting requirements of the national standard JC/T 1025-2007 can be prepared. According to the method, the use way of the titanium gypsum can be broadened, and the gypsum binder prepared from the titanium gypsum can be used together with titanium gypsum blocks, so that better conditions can be provided for use of large amount of titanium gypsum.
Description
Technical field
The invention belongs to gypsum building material technical field, be specifically related to the method that one utilizes titanium gypsum production coventional type (G) bonding gypsum.
Background technology
Along with the production production capacity of China's titanium white powder enterprise constantly increases, the quantity discharged of titanium gypsum increases year by year.Current most domestic titanium white production enterprise is all direct stacking to titanium gypsum, and a large amount of stackings of titanium gypsum not only take a large amount of soil, contaminate environment, returns titanium white production enterprise and brings huge economical load.Titanium gypsum can be utilized effectively become titanium white production enterprise can the key point of sustainable and healthy development.Domestic had titanium white production enterprise to start to utilize titanium gypsum production gypsum block, thus titanium gypsum can be utilized in a large number, utilize titanium gypsum production bonding gypsum can increase the utilization ways of titanium gypsum, the bonding gypsum that titanium gypsum is produced can use together with titanium gypsum building block, thus provides better condition for a large amount of uses realizing titanium gypsum.
summary of the invention:
The object of the invention is to propose a kind of scientific formulation, simple to operate, turn waste into wealth, the method utilizing titanium gypsum production coventional type (G) bonding gypsum of energy-conserving and environment-protective.
Realizing technical solution of the present invention is: the bonding gypsum produced by stirring with the auxiliary material that titanium gypsum, desulfurated plaster and hydraulicity cement are suitable for major ingredient is equipped with, and each raw material obtains by following weight proportion:
Titanium gypsum: 35% ~ 60%
Desulfurated plaster: 30% ~ 60%
Hydraulicity cement: 0% ~ 20%;
The consumption of auxiliary material is to obtain by the part by weight accounting for major ingredient:
Retardant: 0.5 ‰ ~ 5 ‰
Thickening material: 0 ‰ ~ 4 ‰
Binding agent: 0 ‰ ~ 5 ‰
Composite high-early strength water reducer: 0 ‰ ~ 6 ‰.
Described titanium gypsum is the plaster of Paris of titanium gypsum through calcining of titanium white production enterprise by-product.
Described desulfurated plaster is the plaster of Paris of desulfurated plaster through calcining of enterprise's by-products such as coal-burning power plant.
Described hydraulicity cement is 42.5 silicate cements.
Described retardant is gypsum special retarder.
Described thickening material is thickening material Vltra tears general in prior art.
Described binding agent is water-holding agent polyvinyl alcohol 2488 general in prior art.
Described composite high-early strength water reducer is gypsum specific complex early strength water-reducing agent.
The present invention, by being uniformly mixed major ingredient (titanium gypsum, desulfurated plaster and hydraulicity cement) and auxiliary material (retardant, thickening material, binding agent and composite high-early strength water reducer), just can produce coventional type (G) bonding gypsum complied with the national standard requirements.
Beneficial effect of the present invention: utilize the titanium gypsum of titanium dioxide enterprise by-product to produce bonding gypsum, the utilization ways of titanium gypsum can not only be increased, can also use together with titanium gypsum building block, thus provide better condition for a large amount of uses realizing titanium gypsum.
