Description
Technical field
The invention belongs to building material field is and in particular to a kind of mechanical injection wet-mixing motar and preparation method thereof.
Background technology
Ecological Civilization Construction is one of important content that " 13 " plan, economizes on resources and environmental protection is Chinese base
This state basic policy.Develop a circular economy, preserve the ecological environment, the theory built a resource-conserving and environment-friendly society has become society
Can extensively know together.With the lifting of construction level of modernization, China starts to carry out green building, and puts into effect " green building
Evaluation criterion ", be related specifically to energy-saving and emission-reduction.And wet mixing mortar, as novel green construction material, has wide city
Field prospect, then by mechanically spraying it is contemplated that the application of injection wet-mixing motar will bring the significant innovation of field of mortar.
Wet-mixing motar is sprayed using flush coater, replaces the full manual work of traditional mortar, realize commercialization and the construction of mortar
Mechanization, is conducive to improving civilized construction, reduces dust airborne dust, improve construction quality, accelerate speed of application, thus for promoting to send out
Exhibition recycling economy and realize energy-saving and emission-reduction and provide safeguard.
Mechanical injection wet-mixing motar, is the synthesises of wet mixing mortar and mechanized operation.At present, wet mixing mortar is most
Produced in the mixing plant producing concrete, only simply need to be transformed in original mixing plant equipment Foundations, raw material need not
Dry, proportioning is accurate, steady quality, centralized production will not produce secondary pollution.Adopted flush coater to spray, replaced traditional
Manual work and make up the disappearance of the workman that plasters, it is ensured that construction quality on the premise of lifting construction speed.For presently, there are
Scene starch from sand cutting, the easy bleeding of mortar, performance-sensitive, lead to construction quality to be more difficult to get guarantee, additionally, in production process
In can cause a large amount of airborne dusts and sound pollution.Therefore, mechanical injection wet-mixing motar has economic benefit and environmental benefit concurrently, is
The green construction material of novel practical.
The associated documents forbidding Site mortar were assigned, in 2007, by China, and " prohibiting existing " is progressively carried out in each department, to sand
The research in slurry field is more and more deep, and some economically well-developed provinces are more ripe in the application of field of mortar.But, end mesh
Before, the key technology of mechanical injection wet-mixing motar and applied research also do not draw attention in China, are not yet formed so far and produce
Industry.Once mechanical injection wet-mixing motar obtains practical application, it not only can drive the development of related Manufacturing, and expands according to this
Extension stretch formation one complete industrial chain so that China's mortar industry development integrates with advanced international standard, constantly reduce with
The gap of developed country, and the recruitment famine problem that current building trade exists can also be alleviated it is ensured that the sustainable development of building industry
Exhibition.This not only conforms with national green construction material and the development trend of product mechanized operation, also complies with China in " 13 "
The requirement of Ecological Civilization Construction in planning.Therefore, there is civilized construction low degree, long construction period for current industry and plaster
The present situations such as workman's deficiency, design and develop out a kind of mechanical injection wet-mixing motar.
Content of the invention
The present invention be directed to the deficiencies in the prior art it is therefore intended that provide a kind of mechanical injection wet-mixing motar and
