ʻO ka hana ʻana i ke one he hana ia e hoʻohana ana i ka ea i hoʻopaʻa ʻia ma ke ʻano he mana e hoʻokuke i nā mea abrasives i ka ʻili o ka workpiece no ka hana ʻana. ʻO kēia ka mea i kapa ʻia ʻo sandblasting, ʻo ia ka mea a mākou e kapa pinepine ai he shot blasting. No ka mea, i nā lā mua o ka shot blasting, ʻo ke one wale nō ka abrasive i hiki ke hoʻohana ʻia, no laila ua kapa ʻia ka shot blasting he one blasting i kēlā manawa a no ka manawa lōʻihi ma hope. Hiki i ka oneblasting ke hana i ka ʻili e hoʻomaʻemaʻe ʻia e loaʻa i ka maʻemaʻe e pono ai a me kekahi ʻoʻoleʻa, a hoʻomaikaʻi i ka hoʻopili ʻana o ka uhi ma ka ʻili kumu. ʻAʻohe mea pehea ka maikaʻi o ka uhi ʻana, ʻaʻole hiki ke hoʻopili ʻia i ka ʻili o ka workpiece me ka ʻole o ka mālama ʻana i ka ʻili lōʻihi. ʻO ke kumu o ka mālama mua ʻana i ka ʻili, ʻo ia ka hoʻomaʻemaʻe ʻana i ka ʻili a hana i ka ʻoʻoleʻa e pono ai e "laka" i ka uhi ma ka ʻili. Ma hope o ka uhi ʻia ʻana o ka ʻili o ka workpiece i hoʻopaʻa ʻia me kahi uhi ʻoihana hana maikaʻi, ʻo ke ola lawelawe o ka uhi he 3.5 mau manawa ka lōʻihi ma mua o ke ola lawelawe o ka uhi like ma ka ʻili i mālama ʻia e nā ʻano hana ʻē aʻe. ʻO kekahi pono o ka oneblasting (shot blasting) ʻo ia ka hiki ke hoʻoholo mua ʻia ka ʻoʻoleʻa o ka ʻili e like me nā koi a hiki ke hoʻokō ʻia i ka wā o ke kaʻina hana hoʻomaʻemaʻe.
ʻO ka Frosting, no ka laʻana, he kaʻina hana ia eʻōmole aniani hoʻonanililo i laumania a lilo i matte. Hoʻomālamalama ka mālamalama i ka ʻili e hana i ka hoʻomālamalama diffuse. I ka frosting kemika, wili ʻia ke aniani me ka mīkini a wili lima paha me ka emery, ke one silica, ka pauka pomegranate a me nā mea abrasive ʻē aʻe e hana i kahi ʻili ʻino like, a i ʻole hiki ke mālama ʻia ke aniani a me nā mea ʻē aʻe me kahi hopena hydrofluoric acid e hana i ke aniani hau.
Hoʻohana ʻia ka frosting a me ke oneblasting e uhi i ka ʻili aniani, i mea e pālahalaha like ai ke kukui ma hope o ka hala ʻana ma o ke kukui kukui. He mea paʻakikī i nā mea hoʻohana maʻamau ke hoʻokaʻawale ma waena o kēia mau ʻenehana ʻelua. Eia ka mea e wehewehe ana i nā ʻano hana o kēia mau ʻenehana ʻelua a pehea e ʻike ai iā lākou.
1. Ke kaʻina hana hau
ʻO ka hau ʻana e pili ana i ka hoʻoluʻu ʻana i ke aniani i loko o kahi wai waikawa i hoʻomākaukau ʻia (a i ʻole ke kau ʻana i kahi kāpili waikawa), ka ʻōpala ʻana i ka ʻili aniani me ka waikawa ikaika, a ʻo ka hydrogen fluoride ammonia i loko o ka hopena waikawa ikaika e hoʻokumu i ka ʻili aniani i nā kristal. No laila, inā hana maikaʻi ʻia ke kaʻina hana hau ʻana, he laumania loa ka ʻili o ke aniani hau ʻia, a ʻo nā kristal i hoʻopuehu ʻia e hana i kahi hopena noe. Inā ʻano ʻino ka ʻili, hōʻike kēia e hōʻino nui ana ka waikawa i ke aniani, a i ʻole ʻaʻohe kristal o kekahi o lākou. ʻO ke ʻano o kēia kaʻina hana, ʻo ia ka ʻike ʻia ʻana o nā kristal ʻālohilohi ma ka ʻili aniani i hana ʻia ma lalo o nā kūlana koʻikoʻi. ʻO ke kumu nui, ua aneane pau ka hydrogen fluoride ammonia. I mea e hoʻokō ai i kēia kūlana, ua hana nā mea hana he nui i nā hoʻāʻo a me nā haʻawina he nui, akā ʻaʻole i hiki ke lanakila i kēia paʻakikī.
2ʻenehana hoʻoheheʻe one
Hoʻohana ia i nā ʻāpana one i hoʻokuʻu ʻia e ka pū pīpī me ka wikiwiki kiʻekiʻe e kuʻi i ka ʻili aniani e hana i kahi ʻili lahilahi ʻole, a laila e hoʻokō ai i ka hopena o ka hoʻopuehu ʻana i ka mālamalama, a hana i kahi manaʻo noe i ka wā e hele ai ke kukui. He ʻinoʻino ka ʻili o nā huahana aniani i hana ʻia e ke kaʻina hana one. Ma muli o ka hōʻino ʻia o ka ʻili o ke aniani, ua like ia me ke aniani keʻokeʻo ma ke ʻano o ka photosensitivity o ke aniani moakaka mua.
He ʻokoʻa loa nā kaʻina hana ʻelua. ʻOi aku ke kumukūʻai o ke aniani hau ma mua o ke aniani one-blasted, a ʻo ka hopena e pili nui ana i nā pono o ka mea hoʻohana. ʻAʻole kūpono kekahi mau aniani kūikawā no ka hau ʻana. Ma muli o ka hahai hanohano, pono e koho ʻia ka matte. Hiki ke hana ʻia ke kaʻina hana one-blasting ma nā hale hana maʻamau, akā ʻaʻole maʻalahi ka hana ʻana i ke kaʻina hana one-blasting.
