Shield construction is an important link in modern urban construction, and shield mud is a key factor in this process. However, the generation of foam in the shield mud often becomes a construction problem. For this reason, we can choose to add an appropriate amount of shield mud defoamer to avoid foam accumulation and overflow. So,Defoamer for shield slurryWhat are the functions and storage methods? Today, I will explain the relevant knowledge in detail for you, I hope it will be helpful to you.
First, the role of shield mud defoaming
1.Defoaming:The primary function of shield mud defoamer is to quickly eliminate the foam in the mud. The formation of these foams can be due to a variety of reasons such as gas release in the mud, chemical reactions, etc. The shield slurry defoamer can quickly penetrate into the foam, reduce the surface tension, and make the foam burst quickly, so as to achieve the purpose of defoaming.
2.Foam inhibition:Shield mud defoamer has strong antifoam performance. In the process of mud circulation, the shield mud defoamer can inhibit the generation of foam, thus avoiding problems caused by excessive foam, such as increased mud volume, pumping difficulties, etc.
3.Improved Performance:The shield mud defoamer can improve the fluidity of the shield mud, improve the shear stability of the mud, and reduce the water content of the mud, so as to improve the use effect and engineering quality of the mud.
4.Protecting the environment:The addition of shield mud defoamer is low, and the appropriate amount of foam overflow can be avoided when used, which is environmentally friendly and meets the environmental protection requirements of modern engineering. Through the use of shield mud defoamer, the discharge of harmful substances in the mud can be reduced, and the construction site and the surrounding environment can be protected.
Second, the storage method of shield mud defoamer
1.Store it properly:Avoid direct sunlight and high temperature environment to maintain the stability of shield mud defoamer; Keep the storage environment dry to prevent the shield mud defoamer from getting wet, so as not to affect the use effect of the shield mud defoamer.
2.Keep away from fire:Shield mud defoamer is a flammable substance, which should be kept away from fire sources and flammable materials to ensure safe storage. In the process of use, we should also regularly check the storage of shield mud defoamer to ensure that no abnormal phenomena occur.
