conventional packing
1.It offers the advantages of high mass transfer efficiency,low pressure drop,low foaming for the liquid phase,good corrosion resistance,and low cost. This packing has been passed the appraisal by the Chemical Industry Ministry. It appears to be a satisfactory substitute to conventional reinforced PP packing and stainless steel packing.
2.The packing gland for the conventional high-pressure grouting is modified to be adaptable to the low-pressure curtain grouting; by which the application area of the grouting method is enlarged along with improved grouting quality and shortened construction period.
