ARC Speedtex Fine -Silca Carbide - ROTOS & AND SHEET

Made of laminated TNT of micrometric polyester filaments, it has high mechanical strength, waterproofness and resistance to dirt and heat. The fine roller is charged with silicon carbide and it is used to smooth the polyethylene base after dressing the ski structure with the stone grinding machine and whenever the ski base is damaged by abrasion. The filaments of the roller penetrate deeply into the ski structure and have the dual function of detaching the residual polyethylene micro-hairs and orienting the texture of the polymer in the opposite direction to the direction of gliding so that the ski structure becomes more sliding in every direction. The roller must be used before finishing the edges (alpine
discipline) and before the saturation or the protection ski base waxing. 3 working cycles from tip to tail have to be performed at a drill speed of nearly 1000 rpm without exerting pressure. After its use, the ski base must be carefully cleaned with detergent to eliminate processing residues. The grain of the silicon carbide has been carefully chosen to carry out the work detailed here. Numerous tests with the digital roughness tester have found that the use of the micro-abrasive roller does not significantly change the Ra, Rq and Rz of the ski structure on which it is used, a determining factor in order not to alter the research work on the ski structures made by companies and national teams.
