Kumvetsetsa ndondomeko ya mchenga kuphulika makina nzeru wamba ntchito yabwino (Ⅲ)

Kuchepetsa kupsinjika ndi kulimbikitsa pamwamba

Mwa kugunda pamwamba pa workpiece ndi kuwombera mchenga, kupanikizika kumachotsedwa ndipo mphamvu ya pamwamba ya workpiece ikuwonjezeka, monga chithandizo chapamwamba cha workpiece monga akasupe, makina opangira makina ndi masamba a ndege.

Mchenga kuphulika makina kuyeretsa kalasi

Pali miyeso iwiri yoyimira padziko lonse lapansi yaukhondo: imodzi ndi "SSPC-" yokhazikitsidwa ndi United States mu 1985; Yachiwiri ndi "Sa-" yopangidwa ndi Sweden mu 76, yomwe imagawidwa m'magulu anayi, omwe ndi Sa1, Sa2, Sa2.5 ndi Sa3, ndipo ndi muyezo wapadziko lonse lapansi. Tsatanetsatane ndi motere:

Sa1 - yofanana ndi THE US SSPC - SP7. Pogwiritsa ntchito burashi yosavuta Buku, emery nsalu akupera njira, iyi ndi mitundu inayi ya ukhondo ndi amtengo otsika, chitetezo ❖ kuyanika ndi bwino pang'ono kuposa workpiece popanda processing. Muyezo waukadaulo wamankhwala amtundu wa Sa1: pamwamba pa chogwiriracho sayenera kukhala mafuta, mafuta, otsalira otsalira, dzimbiri, utoto wotsalira ndi zinyalala zina. Sa1 imatchedwanso Manual burashi kuyeretsa. (kapena kalasi yoyeretsa)

Sa2 mlingo - wofanana ndi THE US SSPC - SP6 mlingo. Kugwiritsa ntchito sandblasting kuyeretsa njira, amene ndi m'munsi mu sandblasting mankhwala, ndiye, zofunika ambiri, koma chitetezo ❖ kuyanika kuposa burashi burashi kuyeretsa kusintha ambiri. The luso muyezo wa mankhwala Sa2: workpiece pamwamba adzakhala wopanda mafuta, dothi, okusayidi, dzimbiri, utoto, okusayidi, dzimbiri, ndi zinthu zina zachilendo (kupatula zolakwika), koma zolakwika sadzapitirira 33% padziko lalikulu mita, kuphatikizapo mithunzi yaing'ono; Kuwonongeka pang'ono pang'ono chifukwa cha zolakwika kapena dzimbiri; Kuwonongeka kwa khungu ndi utoto wa okosijeni. Ngati pali chobowoka pamalo oyamba a chogwiriracho, dzimbiri pang'ono ndi utoto zimatsalira pansi pabowo. Gulu la Sa2 limatchedwanso kalasi yoyeretsa zinthu (kapena kalasi ya mafakitale).

Sa2.5 - uwu ndi mlingo womwe umagwiritsidwa ntchito nthawi zambiri m'makampani ndipo ukhoza kuvomerezedwa ngati zofunikira zamakono ndi zoyenera. Sa2.5 imatchedwanso pafupi ndi White cleanup (pafupi ndi zoyera kapena zoyera). Sa2.5 luso muyezo: chimodzimodzi monga gawo loyamba la Sa2, koma chilema ndi malire osapitirira 5% padziko pa lalikulu mita, kuphatikizapo mthunzi pang'ono; Kuwonongeka pang'ono pang'ono chifukwa cha zolakwika kapena dzimbiri; Khungu la okosijeni ndi zolakwika za utoto.

Kalasi Sa3 - Yofanana ndi US SSPC - SP5, ndi gulu lachipatala lapamwamba kwambiri pamakampani, omwe amadziwikanso kuti White Cleaning Class (kapena gulu loyera). Sa3 mlingo processing luso muyezo: chimodzimodzi monga Sa2.5 mlingo, koma 5% mthunzi, zolakwika, dzimbiri ndi zina zotero.
