Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009. This standard replaces GB/T 7779-2005 "Centrifuge Model Preparation Method". Compared with GB/T 7779-2005, except for editorial repair The main technical changes changed are as follows. --- Added "Chapter 3 Terms and Definitions" (see Chapter 3); --- Combine the "three-legged centrifuge" with the "flat-plate centrifuge" (see Table 1, Table 1 of the.2005 edition); --- Turn bag centrifuge feature code "dry type" changed to "pressurized type" (see Table 1, Table 1 of the.2005 version); --- Centrifugal discharge centrifuge to increase the characteristic code "variable spiral" (see Table 1, Table 1 of the.2005 edition); --- Separate the sedimentation type and the filter type in the screw discharge centrifuge, and separate the code numbers belonging to the two types of models in the characteristic code, and delete the double Cone, magnetic drum, press and dry type code (see Table 1, Table 1 of the.2005 edition); --- Adding Hastelloy to some materials in contact with the material (see Table 2, Table 1 of the.2005 edition). This standard was proposed by the China Machinery Industry Federation. This standard is under the jurisdiction of the National Separation Machinery Standardization Technical Committee (SAC/TC92).
