Jecha rinoputika muchina wekuchenesa giredhi
Kune mitemo miviri inomiririra utsanana pasi rose: imwe ndiyo "SSPC-" yakagadzwa neUnited States muna 1985; yechipiri ndiyo "Sa-" yakagadzirwa neSweden muna 76, iyo yakakamurwa kuita magiredhi mana, anoti Sa1, Sa2, Sa2.5 naSa3, uye ndiyo mitemo yepasi rose. Tsanangudzo ndeiyi:
Sa1 – yakaenzana neUS SSPC – SP7. Uchishandisa bhurashi remaoko riri nyore, nzira yekukuya jira reemery, iyi ndiyo mhando ina dzekuchena dzakaderera zvishoma, dziviriro yejira iri nani zvishoma pane workpiece isina kugadziriswa. Mwero wehunyanzvi wekurapa weSa1 level: pamusoro peworkpiece hapafanirwe kuonekwa mafuta, mafuta, residual oxide, ngura, residual pendi nedzimwe tsvina. Sa1 inonziwo Manual brush cleaning.

Mwero wehunyanzvi wekurapa Sa2: pamusoro pebasa panofanira kunge pasina mafuta, tsvina, oxide, ngura, pendi, oxide, ngura, nezvimwe zvinhu zvekunze (kunze kwezvikanganiso), asi zvikanganiso hazvifanirwe kudarika 33% yenzvimbo pa square mita, kusanganisira mimvuri midiki; Hushoma hwekusachinja ruvara kunokonzerwa nekusagadzikana kana ngura; Kusagadzikana kweganda nependi yeOxide. Kana paine kupwanyika pamusoro pebasa rekutanga, ngura nependi zvicharamba zviri pasi pegomba. Sa2 grade inonziwo commodity cleaning grade (kana industrial grade).
