According to the understanding of relevant personnel, the new type of shotcrete machine is developing rapidly in today's society. The new type of shotcrete machine has huge advantages, such as high-tech technology, high quality, and these are indicators that people trust, and The new shotcrete machine set off a storm when it appeared, making people crazy. During the operation of the shotcrete machine, we must pay attention to a lot of things, the purpose is to avoid causing safety problems in life. Today we want to explain to you Yes, the dust and rebound control methods of shotcrete machine during operation:
① Control the thickness of one spray layer to avoid falling when the spray layer is too thick.
② Strictly control the working wind pressure of the jet to avoid a large amount of dust at the nozzle.
③ Control the aggregate particle size and sand ratio so that it meets the requirements.
④ The use of composite high-efficiency water-reducing quick-setting agent to increase the viscosity of sprayed concrete can greatly reduce dust and rebound.
⑤ Control the optimal distance between the nozzle and the sprayed surface in the range of 0.6 ~ 1.2m, and the spray angle is preferably vertical rock surface. It must not be greater than 45 °.
