【Abstract】 The application status of PVC resin with high apparent density and moderate oil-absorption rate in chemical building materials industry was introduced. The influential factors on high apparent density and moderate oil-absorption rate in resin production was analyzed. It was pointed that the up-to-standard products could be obtained by some improvement measures, such as choosing suitable stir speed and agitator structure, taking closed-feed and controlling pH value, etc.更多还原
