Description
Technical field
The present invention relates to building material technical fields, and in particular to a kind of wear-resistant lightweight spraying gypsum mortar and its construction
Method.
Background technique
Gypsum is a kind of time-honored gel rubber material, it and lime, cement are listed as in first machine cementitious material three big
Pillar.Early in B.C. 2000~3000 years, people began to association using gypsum and lime, as ancient egypt pyramid and
The building of other many grandnesses is all that gypsum, lime is used to build as cementitious material.Using gypsum material for saving
Building resource, raising building material technology level have great significance.It usually has the spies such as light weight, sound insulation, fire resisting, insulation
Point, and gypsum resource is abundant, therefore gypsum is widely used in the field of building materials.In recent years due to state control temperature
The reinforcement of room gas discharge, a large amount of desulfurized gypsums that Desulphurization for Coal-fired Power Plant is formed are also formed for the strong of natural gypsum resource
Supplement.
At abroad, especially European, almost all of gypsum is all used in building material industry, about its application technology
Highly developed, the problems such as the very good solution transport of gypsum, blocking, dry, calcining, the industrial equipment that gypsum utilizes has been
Through specialized, seriation.Gypsum application is earliest and most preferably Japanese in the world, followed by the European countries such as Germany, France.And
The history of China's gypsum production is very short, and comprehensive utilization is also at the early-stage, is applied to generally recognize deficiency with the market competitiveness,
As the second largest solid waste of thermal power plant, not only land occupation resource, and also it is unfavorable to environment.If cannot handle well
And utilization, a large amount of landfill soil is not only occupied, but also pollution is generated to ecological environment.
Building gypsum has many excellent performances, and the application in construction material is also very extensive.It is each in addition to being used to do
Outside kind plasterboard, cement retarder, gap filler and art of architecture accessory, it is mainly used to make to build plastering, painting stone in mortar
The dry-mixed mortars product such as cream.
The traditional construction technique of interior painting gypsum mortar is identical as cement mortar, is all made of the mode manually plastered and carries out
Construction, can be improved house quality, but it will be constructed twice, and construction process is complicated, time and effort consuming.With China's economic
Flourish, construction quickly, the ability of high quality buildings it is most important, with the development of industrial technology, traditional labour is close
The Building technology of collection type also gradate for one more industrialize form, " settling at one go " machine spray gypsum mortar also meet the tendency of and
It is raw.
Machine spray gypsum mortar is a kind of novel green structural material, is the product mix of organic material and inorganic material,
A variety of organic chemistry additives are added on original material, chemical reaction is generated when water being added to be mixed, and form a kind of gluey sand
Slurry.Since various new additive is added, cohesive force is strong, and compression strength is high, and excellent water conservation will not be caused excessively in too fast dehydration
Cracking, hardening process is not in crawling phenomenon, exempts the maintenance cost of later period valuableness.Foreign countries are universal in the seventies
It replaces artificial handwork to improve quality and efficiency using mechanized manner, reduces cost.Up to the present, brushing gypsum class
95% or more construction be all made of mechanized construction.In order to increase production efficiency in present construction, construction industry is substantially
White washed wall work will be carried out using Mortar spraying machine, the efficiency of work is more much faster than artificial, reduces many labours.
Summary of the invention
The technical problem to be solved by the present invention is to overcome current material to mechanized construction serious wear, cause machine fixed
Son is damaged with rotor, and replacement is too fast, improves the technological deficiency of construction cost, provides a kind of wear-resistant lightweight spraying gypsum mortar
And its construction method.Construction method of the present invention is a kind of simple, effective machine spray gypsum technology, for building brushing gypsum
Labor intensity is reduced in industry and improves construction efficiency.The present invention had not only reduced the abrasion of flush coater stator rotor, but also improved
Workability enhances spray efficiency, in conjunction with construction method of the invention, constructs without hollowing cracking, obscission over 1 year, greatly
Construction cost is reduced greatly, plays certain guidance and impetus for spraying gypsum building construction development from now on.
The present invention solves technological means used by above-mentioned technical problem are as follows:
