Hoʻomaha i ke kaumaha a me ka hoʻoikaika ʻana i ka ʻili
Ma ke kuʻi ʻana i ka ʻili o ka workpiece me ke kī ʻana i ke one, ua hoʻopau ʻia ke kaumaha a ua hoʻonui ʻia ka ikaika o ka ʻili o ka workpiece, e like me ka mālama ʻana i ka ʻili o ka workpiece e like me nā pūnāwai, nā mea hana mīkini a me nā pahi mokulele.
Papa hoʻomaʻemaʻe mīkini hoʻoheheʻe one
ʻElua mau kūlana honua no ka maʻemaʻe: ʻo kekahi ka "SSPC-" i hoʻokumu ʻia e ʻAmelika Hui Pū ʻIa i ka makahiki 1985; ʻO ka lua ka "Sa-" i hoʻokumu ʻia e Suedena i ka makahiki 76, i māhele ʻia i ʻehā mau papa, ʻo ia hoʻi ʻo Sa1, Sa2, Sa2.5 a me Sa3, a ʻo ia ke kūlana maʻamau o ka honua. Eia nā kikoʻī:
ʻO Sa1 - like me THE US SSPC - SP7. Ma ka hoʻohana ʻana i ka palaki lima maʻalahi maʻamau, ke ʻano wili lole emery, ʻo kēia nā ʻano maʻemaʻe ʻehā he haʻahaʻa haʻahaʻa, ʻoi aku ka maikaʻi o ka pale ʻana o ka uhi ma mua o ka workpiece me ka ʻole o ka hana ʻana. ʻO ke kūlana loea o ka mālama ʻana i ka pae Sa1: ʻaʻole pono e ʻike ʻia ka ʻili o ka workpiece i ka ʻaila, ka momona, ke koena oxide, ka ʻōpala, ke koena pena a me nā lepo ʻē aʻe. Ua kapa ʻia ʻo Sa1 ʻo ka hoʻomaʻemaʻe palaki lima. (a i ʻole ka papa hoʻomaʻemaʻe)
Pae Sa2 — like me ka pae US SSPC — pae SP6. ʻO ka hoʻohana ʻana i ke ʻano hoʻomaʻemaʻe oneblasting, ʻo ia ka mea haʻahaʻa i ka mālama ʻana i ka oneblasting, ʻo ia hoʻi, nā koi maʻamau, akā ʻo ka pale ʻana o ka uhi ʻana ma mua o ka hoʻomaʻemaʻe pulumu lima e hoʻomaikaʻi i nā mea he nui. ʻO ke kūlana loea o ka mālama ʻana iā Sa2: ʻaʻohe momona, lepo, oxide, popo, pena, oxide, corrosion, a me nā mea ʻē aʻe (koe wale nō nā hemahema), akā ʻaʻole e ʻoi aku nā hemahema ma mua o 33% o ka ʻili no ka mika kuea, me nā aka iki; He liʻiliʻi o ka discoloration iki i hoʻokumu ʻia e nā hemahema a i ʻole ka popo; ʻO ka ʻili oxide a me nā hemahema pena. Inā he dent ma ka ʻili mua o ka workpiece, e waiho iki ka popo a me ka pena ma lalo o ka dent. Ua kapa ʻia hoʻi ʻo Sa2 grade he commodity cleaning grade (a i ʻole ka papa ʻoihana).
Sa2.5 – ʻo kēia ka pae i hoʻohana pinepine ʻia i ka ʻoihana a hiki ke ʻae ʻia ma ke ʻano he koi loea a me ke kūlana. Ua kapa ʻia ʻo Sa2.5 ʻo ka hoʻomaʻemaʻe kokoke i ke keʻokeʻo (kokoke i ke keʻokeʻo a i ʻole ke keʻokeʻo ʻole). Kūlana loea Sa2.5: like ia me ka ʻāpana mua o Sa2, akā ua kaupalena ʻia ka hemahema ʻaʻole i ʻoi aku ma mua o 5% o ka ʻili no kēlā me kēia mika kuea, me ke aka iki; He wahi liʻiliʻi o ka hoʻololi ʻana i ke kala i hoʻokumu ʻia e nā hemahema a i ʻole ka popo; Nā hemahema o ka ʻili oxide a me ka pena.
Papa Sa3 — Like me ka US SSPC — SP5, ʻo ia ka papa lapaʻau kiʻekiʻe loa ma ka ʻoihana, i ʻike ʻia hoʻi ʻo ka Papa Hoʻomaʻemaʻe keʻokeʻo (a i ʻole ka papa keʻokeʻo). ʻO ke kūlana loea hana pae Sa3: like me ka pae Sa2.5, akā pono e loaʻa ka aka 5%, nā kīnā, ka ʻōpala a pēlā aku.
