Abstract
The invention relates to an improved technique of a manufacturing technique method of an industrial abrasive tool, namely an abrasive belt, in particular to a high-quality curing process method for an abrasive paper volume. The high-quality curing process method for the abrasive paper volume is characterized in that the abrasive volume is put in a specially-made circulation heating humidifying curing oven to be cured. The high-quality curing process method for the abrasive paper includes the following steps: (1) turning down an air port of a heating drought fan, namely low temperature is ranged from 80 DEG C to 85 DEG C in early period, and heating time is 18-19h, (2) turning up the air port of the heating draught fan, namely high temperature is ranged from 115 DEG C to 120 DEG C in middle period, and heating time is 21-22h, and (3) turning down the air port of the heating drought fan, namely low temperature is ranged from 80 DEG C to 85 DGE C in later period, heating time is 6-7h, and humidifying the abrasive paper volume at the same time to ensure that a paper substrate is not damaged, this period of time is time of anti-edge sticking, anti-edge damage and anti-carbonization, and humidifying time is a later low temperature primary stage and is 4-5h, humidification amount is controlled in 3-6 kg/m<3>. By means of the high-quality curing process method for the abrasive paper volume, such problems as being difficult in control, instable in quality, low in product percentage of pass, large in energy consumption and the like in a traditional abrasive paper curing method through a directly-heated type curing oven are solved. The high-quality curing process method for the abrasive paper volume is especially suitable for curing of bulky abrasive paper volume.
