| Abstract: | A new kind of fluidized agitating ball mill named SM-10 is used as grinding machine, and composite activator is used as coupling agent and grinding aids. Calcium carbonate is activated and modified while it is being grinded into ultrofines. And then the activated calcium carbonate is filled into high molecular weight PVC. . The results show that the notch impact strength of sample is higher than 7kJ/m2 , and the tensile strength is higher than 20MPa when calcium carbonat as filler is 70 phr. The effects of the SM-10 processing and PVC plate press processing and amounts of plastisizer and composite activator and filling rate of calcuim carbonate on properties of PVC plate are discussed. |
