铝碳质滑板以热处理过的树脂如酚油中分离出的碳为结合剂 ,所以提高碳的抗氧化性对提高滑板的性能至关重要。在选择抗氧化剂时 ,那些在反应时产生体积膨胀并能填充耐火材料气孔的添加剂被优先选用。试样的基本组成为烧结氧化铝、沥青粉末、碳化硅、二氧化硅粉末和结合剂 ,然后? Aluminum carbon skateboards are made from heat-treated resins such as carbon separated from phenolic oils, so improving the oxidation resistance of carbon is crucial to improving the performance of skateboards. In the selection of antioxidants, those that generate volume expansion during the reaction and can fill the pores of the refractory are preferred. The basic composition of the sample is sintered alumina, pitch powder, silicon carbide, silica powder and binder, then?
