This document replaces GB/T 28627-2012 "Plastering Gypsum": Compared with GB/T 28627-2012, except for structural adjustments and editorial changes
In addition to the dynamics, the main technical changes are as follows:
a) Changed the definition of the term "plastering gypsum" (see 3:1, 3:1 of the:2012 edition);
b) Deleted the term "surface plaster plaster" (see 3:2 of the:2012 edition);
c) "Lightweight plastering gypsum" is changed to "lightweight plastering gypsum" (see 3:2, 3:4 of the:2012 edition);
d) "Bottom plastering gypsum" is changed to "heavy plastering gypsum" (see 3:3, 3:3 of the:2012 edition);
e) Delete the term "insulation layer plastering gypsum" (see 3:5 of the:2012 edition);
f) Changed the classification and marking (see Chapter 4, Chapter 4 of the:2012 edition);
g) Changed the general requirements (see Chapter 5 of the 5:2012 edition);
h) Delete the technical requirements for fineness (see 6:1 of the:2012 edition);
i) Changed the technical requirements for water retention (see Chapter 6, 6:3 of the:2012 edition);
j) Increased calcium sulfate content, pH, radionuclide limit indicators (see Chapter 6);
k) The technical requirements for the strength of plastering gypsum on the surface layer and plastering plaster on the insulation layer are deleted (see 6:4 of the:2012 edition);
l) The technical requirements for the bulk density of the plastering gypsum for the insulation layer have been deleted (see 6:5 of the:2012 edition);
m) Delete the technical requirements for thermal conductivity (see 6:6 of the:2012 edition);
n) The water retention rate measuring device is changed to a water retention rate tester (see 7:1:9, 7:1:10 of the:2012 edition);
o) Delete the fineness test method (see 7:4:1 of the:2012 edition);
p) The water retention test method has been changed (see 7:5, 7:4:3 of the:2012 edition);
q) The test method for tensile bond strength has been changed (see 7:7:3, 7:4:4:3 of the:2012 edition);
r) Delete the thermal conductivity test method (see 7:4:6 of the:2012 edition);
s) Added calcium sulfate content, pH, radionuclide limit test methods (see 7:8, 7:9, 7:10);
t) Determination of calcium sulfate content --- drying difference method has been added (see Appendix A):
