1. Wehe ʻeleʻele lima: Ka hoʻohana ʻana i nā mea hana lima e like me ka pepa hao, ka ʻōpala, ka spatula, a me ka pulupulu uea.ʻO kēia kaʻina hana he kiʻekiʻe o ka hana, haʻahaʻa haʻahaʻa ka hana hana, akā maʻalahi a maʻalahi hoʻi ka hana.
2. Hoʻopau ʻana i ka ʻōpala mīkini: Ke hoʻohana nei i ka hopena a me ka friction o ka mana mechanical e wehe i ka ʻōpala.ʻO nā mīkini i hoʻohana pinepine ʻia, ʻo ia ka pulupulu makani, ka pū hoʻohemo ʻōpala, ka pulupulu uila, ka huila one uila, etc. Hiki ke hoʻouka ʻia nā ʻāpana kila liʻiliʻi i loko o nā bākeke i hoʻopiha ʻia me ke one melemele a i ʻole nā ʻāpana lāʻau a neʻe i ka wikiwiki o 40-60 rpm.Ma o ka collision friction, kiʻekiʻe ka hana pono a me ka maikaʻi maikaʻi maikaʻi hoʻoneʻe rust maikaʻi, i hoʻohana nui ʻia.
3. Injection rust wehe: Powered me ka mechanical centrifugal ikaika a i compressed ea a me kiʻekiʻe puʻe wai, e pulupulu i ka abrasive (ke one a kila paha poepoe) i loko o ka workpiece ili ma ka kiʻekiʻe wikiwiki ma o kūikawā nozzle, a wehe i ka lepo (me ka poino ili pena kahiko. ) a me ka corrosion me kona hopena ikaika a me ka friction, me ka hana hana kiʻekiʻe a me ka maikaʻi o ka mālama ʻana.Hoʻopili iki ʻia ka ʻili kila sandblasted e hoʻonui i ka ikaika paʻa o ka uhi a me ka ʻili kila.Akā, ʻaʻole pono e ʻoi aku ka nui o kona ʻano ma mua o 1/3 o ka mānoanoa o ka uhi.ʻO nā ʻano hana hoʻoneʻe ʻōpala maʻamau i hoʻohana ʻia, ʻo ia ka hoʻoheheʻe ʻana i ke one maloʻo, ka puhi ʻana i ke one pulu, ka puhi ʻana i ke one lepo ʻole a me ka pahū ʻana o ke one wai kiʻekiʻe.
4. Wehe 'ele'ele kemika: Me ka ho'ohana 'ana i ka waika a me ka hao oxides, e ho'ohehe'e a ihi i ka papa lepo lepo e ho'okō ai i ke kumu o ka wehe 'ana i ka lepo.No laila ua ʻike ʻia ʻo ia ʻo "washing acid" a me ka pale ʻana i ka ʻōpala.Nui nā ʻano hana no ka wehe ʻana i ka ʻōpala kemika, ʻo ka maʻamau ka hoʻohana ʻia ʻana o ka solution sulfuric acid o 7% a 15% (a i ʻole 5% paʻakai pākaukau) ma ke ʻano he hopena hoʻohemo ʻana i ka lepo.I mea e pale aku ai i ka palaka sulfate o ke kila, hiki ke hoʻohui ʻia kahi mea liʻiliʻi o nā mea hoʻopiʻi corrosion e like me rodine a me thiourea.Eia kekahi, hiki iā ia ke hoʻohana i ka waikawa phosphate, ka waikawa nitrate, ka waika hydrochloric a pēlā aku e hana ai i ka wai holoi ʻokoʻa a me ka hoʻopau ʻana i ka wai.Nui nā ʻano o ka pickling, maʻamau ka hoʻohana ʻana i ke ʻano holoi holoi waika impregnated, ke ʻano hoʻoheheʻe pickling.Ma waho aʻe o ka ʻakika acid, e pili ana i nā kūlana kikoʻī.
