Description
Technical field
The present invention relates to a kind of additive for spray plaster mortar, especially apply in dry-mixed mortar and premixing coagulation
Additive in soil, belongs to building material technical field.
Background technology
With the continuous development of society, human cost more and more higher, the requirement for engineering construction quality and efficiency of construction
Also more and more higher, spray plaster mortar additive can become possible to machine spraying mortar, and be obviously improved spraying mortar
Quality and efficiency, the quality wiped one's face of the interior wall exterior wall sand pulp made becomes higher, more efficient, construction it is also safer.Can
To save manpower more than 80%.Possesses huge economic benefit.
Certain building site practical effect contrast：
| Project | Manually wipe one's face | Machine spraying is not added with additive | Machine spraying plus additive |
| Efficiency of construction | 8 square meters/work day | 500 square meters/machine-team | 800 square meters/machine-team |
| Construction quality | Drum easily is opened, ftractures, comes off | Quality is general, easy to fall off | Quality is preferable |
| People's number | The square meter of 1250 work days/10000 | The square meter of 160 work days/10000 | The square meter of 110 work days/10000 |
| Labor intensity | It is very high | It is relatively low | It is low |
| Environment | There is pollution | Pollution is lighter | Substantially it is pollution-free |
| Surface strength | Typically | Typically | It is high |
| Hollowing, expulsion rate | 23.50% | 12.40% | 1.50% |
| Repair rate | 25% | 18.50% | 2.50% |
| Cost accounting | 11.5 yuan/square meter | 10.3 yuan/square meter | 9.2 yuan/square meter |
Machine sprays at this stage, because the raw material and proportioning of each local mortar are not quite similar, causes actually to use machine
The performance that device spraying mortar is showed not is ideal, so, it is badly in need of a kind of mortar additive now, to improve direct use
The some shortcomings of machine spraying, the workability of mortar is improved, betterment works quality, improves operating efficiency so that use machine
The efficiency for spraying mortar is smeared apparently higher than artificial, is more easy to promote.This mortar additive volume is small, can make according to engineering is actual
It is adjusted with situation.
The content of the invention
A kind of additive for spray plaster mortar is provided the invention aims to overcome above-mentioned deficiency, can be with
Mortar is possessed sprayability, firmly can be bonded together with metope, non-stick knife non-stick knife is easy to levelling construction.
To achieve the above objectives, the present invention is achieved by the following technical solutions：
A kind of additive for spray plaster mortar, it is made up of the raw material of following weight part ratio：
