Embodiment Construction
[0016] The specific method of adopting the solidified sandpaper roll of the present invention is: put the sandpaper roll into a special circulating heating humidification curing furnace for curing, and the operation steps are as follows:
[0017] (1) The air outlet of the heating fan is adjusted down, that is, the low temperature in the early stage is 80°C-85°C, specifically 85°C, and the heating time is 18-19h, specifically 18h; The dynamic switching of the circulation direction makes the temperature of the sandpaper roll from the outside to the inside reach the temperature, and then change the temperature;
[0018] (2) Increase the air outlet of the heating fan, that is, the mid-term high temperature is 115°C-120°C, specifically 115°C, and the heating time is 21-22h, specifically 22h; this period of time is the curing time, and the time is extended;
[0019] (3) Turn down the air outlet of the heating fan, that is, the low temperature in the later stage is 80°C-85°C, specif...

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.
Description
technical field [0001] The invention relates to an improved technology for the production process of abrasive belts for industrial abrasive tools, in particular to a high-quality solidification process for sandpaper rolls. Background technique [0002] At present, the curing process of domestic sandpaper rolls is carried out by traditional direct-heating curing furnaces. The problems of this curing method are: (1) It is difficult to control the degree of curing of sandpaper rolls in direct-heating curing furnaces, and only by experience or According to the feeling; (2) The sandpaper roll cured by the direct heating curing furnace is seriously stuck to the edge, which makes the next process difficult to operate or a large number of broken edges, and the product qualification rate is low; (3) The whole process of curing in the direct heating curing furnace is The same constant temperature prolongs the curing time, which not only consumes a lot of energy, but also has a long pr...
