[0037] 1.1 Process route
[0038] 1.2.1 Gluing of hemp rope: roll a circle of glue on the processed sisal fiber rope (: modified liquid phenolic resin 65%, filler: 35%, glue solid content: 75-77% , The amount of glue is: 0.7-0.8g per gram of sisal fiber rope), and then bake at 70±2℃ for 30min.
[0039] 1.2.2 Wrap the glued fiber rope on the mold according to the established route, and then put it into the mold cavity, press the shape, and bake at 120℃ for 4-6h (the flat polishing wheel is cured for 4h, the circumferential polishing wheel is cured 6h), slowly cool down to room temperature, and then release the mold.
[0040] 1.3 The test production style is: flat polishing wheel: outer diameter is 4 inches (101.6-103mm), inner diameter is 55mm, hole diameter is 16mm, thickness 6-8mm); circular polishing wheel: outer diameter is 10.6 inches (270mm) hole diameter is 32mm, thickness 30mm).
