Alum\u012bnija oks\u012bds un sil\u012bcija karb\u012bds ir divi popul\u0101ri abraz\u012bvie materi\u0101li, ko izmanto met\u0101la un koka izstr\u0101d\u0101jumiem. Ide\u0101l\u0101 materi\u0101la izv\u0113le ir atkar\u012bga no lietojuma vajadz\u012bb\u0101m un v\u0113lam\u0101 apdares veida.<\/p>\n
Sil\u012bcija karb\u012bds lepojas ar asiem k\u0101 dzirnakmens graudiem, kas ar minim\u0101lu sp\u0113ku bez piep\u016bles sagrie\u017e cietus met\u0101lus, koka un stikla virsmas, k\u0101 ar\u012b ir piem\u0113rots nemet\u0101liskiem vai zemas stiepes iztur\u012bbas materi\u0101liem.<\/p>\n
Alum\u012bnija oks\u012bds ir viens no vispiepras\u012bt\u0101kajiem abraz\u012bviem materi\u0101liem, kas ir paz\u012bstams ar savu ilgo kalpo\u0161anas laiku un daudzpus\u012bgo pielietojumu da\u017e\u0101dos materi\u0101los. Tas izce\u013cas ar \u0101tru no\u0146em\u0161anu, neboj\u0101jot virsmas - ide\u0101ls risin\u0101jums, kad laiks ir \u013coti svar\u012bgs.<\/p>\n
