Qonda inqubo yokuqhuma kwesihlabathi umshini ojwayelekile wokusebenza okulula (ⅲ)

Ukukhululeka kwengcindezi kanye nokuqiniswa komhlaba

Ngokushaya indawo yomsebenzi wesihlabathi ngokudutshulwa, ukucindezelwa kuqediwe futhi amandla angaphezulu okusebenza akhuphukile, njengokuphathwa komhlaba kwendawo yokusebenza njengeziphethu, amathuluzi wemishini kanye nama-blade endiza.

Ibanga Lokuhlanza Umshini Wokuhlanza Umshini

Kunamazinga amabili amele amele enhlanzeko: Yinye "i-SSPC-" esungulwe yi-United States ngo-1985; Okwesibili yi- "SA-" enziwe yiSweden ngo-76, ehlukaniswe amamaki amane, okungukuthi i-SA1, SA2, SA2.5 ne-SA3, futhi iyindinganiso yamazwe omhlaba. Imininingwane imi ngalendlela elandelayo:

I-SA1 - okulingana ne-US SSPC - SP7. Usebenzisa i-General Simple Blue Manual Brashing, indlela ye-Emery Chadoring, lena yilezi zinhlobo ezine zokuhlanzeka okuphansi ngokulingana, ukuvikelwa kwe-coating kungcono kakhulu kunokwenza umsebenzi wokusebenza ngaphandle kokulungiswa. Izinga lobuchwepheshe ukwelashwa kwe-SA1 level of SA1, ingaphezulu kwe-workpiece akufanele kube ngamafutha abonakalayo, amafutha, ama-oxide asalayo, ukugqwala, upende osele kanye nokungcola okusele. I-SA1 ibizwa nangebhulashi yokuhlanza ibhulashi. (noma ikilasi lokuhlanza)

Ileveli ye-SA2 - okulingana ne-US SSPC - Izinga le-SP6. Ukusetshenziswa kwendlela yokuhlanza ye-sandblasthing, okuyinto ephansi ekwelashweni kwe-sandblasting, okungukuthi, izidingo ezijwayelekile, kepha ukuvikelwa kokuhlanganiswa kwe-coation kunamabhulukwe okuhlanza ukuthuthukisa abaningi. I-Technical Livest of SA Hartshont: I-WorkPere Surface izokhululeka kumafutha, ukungcola, i-oxide, ukupenda, iziphikiso), kepha amaphutha ngeke angeqi ama-33% wemitha ngalinye, kufaka phakathi izithunzi ezincane; Inani elincane lokudilizwa okuncane okubangelwa iziphambeko noma ukugqwala; Isikhumba se-oxide kanye nezinkinga zokupenda. Uma kukhona i-dent ebusweni bokuqala bokusebenza, ukugqwala okuncane nopende kuzohlala phansi kwe-dent. I-SA2 Ibanga libizwa nangokuthi ibanga lokuhlanza impahla (noma ibanga lezimboni).

I-SA2.5 - Leli lizinga elisetshenziswa kakhulu embonini futhi lingamukelwa njengemfuneko yezobuchwepheshe kanye ne-standard. I-SA2.5 ibizwa nangokuhlanza okumhlophe (eduze kokumhlophe noma okumhlophe). I-SA2.5 ENGCELWENI YOKUQALA: Ngokufana nengxenye yokuqala ye-SA2, kepha lesi sici sinqunyelwe ngaphezu kwama-5% omphezulu ngemitha ngayinye, kufaka phakathi isithunzi esincane; Inani elincane lokudilizwa okuncane okubangelwa iziphambeko noma ukugqwala; Isikhumba se-oxide kanye nezinkinga zokupenda.

I-Class SA3 - okulingana ne-US SSPC - i-SP5, ikilasi lokwelashwa eliphakeme embonini, elaziwa nangokuthi isigaba sokuhlanza esimhlophe (noma isigaba esimhlophe). Izinga le-SA3 licubungula izinga lobuchwepheshe: okufanayo ne-SA2.5 level, kepha isithunzi esingu-5%, amaphutha, ukugqwala nokunye okunjalo kufanele kube khona.
