With the increase of the requirements for the construction environment, most of the construction sites have adopted wet spray technology, and gradually abandoned the dry spray. How to choose a wet shotcrete machine?
The dry spray process has the advantages of low cost, simple and durable, but also has many defects, such as poor spray quality, low production efficiency, high rebound rate, and easy environmental pollution. It is also harmful to the health of operators. However, there are many advantages of wet spraying, high productivity, high quality control, no dust, low rebound rate, and easy control of water-cement ratio when mixing concrete. In comparison, the wet spray process inevitably occupies the dominant position of the coagulation spray process.
At present, more large-scale wet shotcrete machine with telescopic arms are used. The equipment is simple and efficient, the spray speed is fast, the range is wide, and the movement is convenient. It can effectively improve the construction progress and cycle speed. It can not only reduce the dust concentration during construction It also protects the physical health of the workers, and the desktop wet spray coagulant is automatically and accurately added, eliminating a lot of human factors, so that the strength of the coagulant is guaranteed.
