Jecha blasting machine yekuchenesa giredhi
Kune miviri miviri inomiririra mitemo yepasi rose yehutsanana: imwe ndiyo "SSPC-" yakatangwa neUnited States muna 1985; Yechipiri ndiyo "Sa-" yakagadzirwa neSweden muna 76, iyo yakakamurwa kuva magiredhi mana, anoti Sa1, Sa2, Sa2.5 uye Sa3, uye ndiyo chiyero chepasi rose. Details ndeiyi:
Sa1 - yakaenzana neUS SSPC - SP7. Uchishandisa yakajairwa yakapusa bhuku bhurashi, emery jira rekukuya nzira, aya marudzi mana ehutsanana ane mwero akadzikira, kuchengetedzwa kwekupotera kuri nani zvishoma pane workpiece pasina kugadzirisa. Technical standard yeSa1 level kurapwa: pamusoro peiyo workpiece haifanirwe kunge inoonekwa mafuta, girizi, yakasara oxide, ngura, pendi yakasara uye imwe tsvina. Sa1 inonziwo Manual brush cleaning. (kana kirasi yekuchenesa)
Sa2 level - yakaenzana NEUS SSPC - SP6 level. Kushandiswa kwejecha rekuchenesa nzira, iyo yakaderera mukurapa kwejecha, kureva, izvo zvinodiwa, asi kuchengetedzwa kwekuputira pane bhuku rekuchenesa bhurashi kuvandudza akawanda. Iyo tekinoroji chiyero cheSa2 kurapwa: iyo workpiece pamusoro haizove isina girizi, tsvina, oxide, ngura, pendi, oxide, ngura, uye zvimwe zvinhu zvekune dzimwe nyika (kunze kwekuremara), asi kuremara hakuzopfuure 33% yepasi paskweya. mita, kusanganisira mimvuri mishoma; Kuderera kuduku kwemavara kunokonzerwa nekuremara kana ngura; Oxide ganda uye pendi kukanganisa. Kana pane dent munzvimbo yepakutanga ye workpiece, zvishoma ngura uye pendi zvicharamba zviri pasi pe dent. Sa2 giredhi inonziwo commodity cleaning giredhi (kana maindasitiri giredhi).
Sa2.5 - iyi ndiyo nhanho inowanzoshandiswa muindasitiri uye inogona kugamuchirwa sezvinodiwa zvehunyanzvi uye chiyero. Sa2.5 inonziwo pedyo neWhite cleanup (pedyo nechena kana kunze kwechena). Sa2.5 technical standard: yakafanana neyokutanga chikamu cheSa2, asi kuremara kunogumira kwete kupfuura 5% yepasi pemamita mita, kusanganisira mumvuri mudiki; Kuderera kuduku kwemavara kunokonzerwa nekuremara kana ngura; Oxide ganda uye pendi kukanganisa.
Kirasi Sa3 - Yakaenzana neUS SSPC - SP5, ndiyo yepamusoro kirasi yekurapa muindasitiri, inozivikanwawo seyechena Yekuchenesa Kirasi (kana chena kirasi). Sa3 level processing technical standard: yakafanana neSa2.5 level, asi 5% mumvuri, kuremara, ngura uye zvichingodaro zvinofanira kuvapo.
