1. The low temperature will cause freezing and thawing of stone

The phenomenon of freezing and bridge cutting machine granite thawing is that when the stone is cold in winter, the inside or the periphery of the stone cracks is frozen, resulting in expansion. The stress caused by the freezing of water in multi blade cutting machine the pores of the stone is one of the reasons for the cracks of the stone. Those who understand the principles of physics and chemistry know that the smaller the pore diameter of the stone, the lower the vapor pressure of the water in the pore and the lower the freezing point. In some extremely fine pores, the freezing point of water can drop by tens of degrees Celsius. Therefore, the stone with smaller pores is not easy to be damaged quarry stone block cutting machine by freezing, while the stone with larger pores, such as magnificent and golden beige, is easy to be damaged by freezing in the treatment of granite block cutter cracks.

In order to avoid and reduce the damage to the surface of the stone by freezing and thawing, we must take precautions in advance for the stone that often encounters water indoors and outdoors to prevent the stone from inhaling a large amount of water and causing the granite block cutting machine price stone to freezing.

2. It is necessary to prevent the influence of snow melting agent on a stone on snowy days

After the snow, in order to prevent slippery roads or to remove snow quickly, industrial snow melting agents are often sprayed on the road. A snow melting agent is a chemical agent that can lower the melting temperature of snow and ice. Its main ingredients are potassium acetate and chloride. Commonly used snow melting agents are generally low-priced chlorine salts, which are corrosive to asphalt roads to a hydraulic block cutter certain extent.

The snow-melting agent thrown multi blade granite cutting machine on the road is brought to the stone floor of the building hall by pedestrian shoes, which will corrode the stone floor and cause the ground to lose its light. In view of this situation, we need to lay the outdoor wiper mat in advance, and the indoor stone floor should also be laid with absorbent stone block cutter mats to make a defense system. After the ice and snowmelt, clean the floor of the hall in time, remove the residual snow melting agent, and do a good job of crystallizing and polishing the stone surface.
