ʻO ka Sandblasting kahi hana e hoʻohana ai i ka ea i hoʻopaʻa ʻia ma ke ʻano he mana e pana i nā abrasives i ka ʻili o ka mea hana no ka hana ʻana.ʻO kēia ka mea i kapa ʻia he sandblasting, ʻo ia ka mea a mākou e kapa pinepine ai i ka pana pana.No ka mea, i nā lā mua o ka puhi kī ʻana, ʻo ke one wale nō ka mea abrasive hiki ke hoʻohana ʻia, no laila ua kapa ʻia ʻo ka puhi ʻana i ke one i ia manawa a no ka manawa lōʻihi ma hope.Hiki i ka Sandblasting ke hoʻomaʻemaʻe i ka ʻili e loaʻa ai ka maʻemaʻe i koi ʻia a me kekahi ʻano ʻino, a hoʻomaikaʻi i ka pili ʻana o ka uhi ma ka ʻili kumu.No ka maikaʻi o ka uhi ʻana, ʻaʻole hiki ke hoʻopili ʻia i ka ʻili o ka mea hana me ka ʻole o ka mālama ʻana i ka ʻili lōʻihi.ʻO ke kumu o ka hoʻomaʻemaʻe ʻana i ka ʻili e hoʻomaʻemaʻe i ka ʻili a hana i ka ʻawaʻawa e pono ai e "laka" i ka uhi ʻana ma luna o ka ʻili.Ma hope o ka uhi ʻia ʻana o ka ʻili o ka mea hana sandblasted me kahi ʻoihana hana maikaʻi, ʻoi aku ka lōʻihi o ke ola lawelawe o ka uhi ʻana ma mua o ke ola lawelawe o ke ʻano like ʻole o ka uhi ʻana i ka ʻili i mālama ʻia e nā ʻano hana ʻē aʻe.ʻO kekahi pōmaikaʻi ʻē aʻe o ka sandblasting (shot blasting) ʻo ia ka hiki ke koho mua ʻia ka ʻili o ka ʻili e like me nā koi a hiki ke hoʻokō ʻia i ka wā hoʻomaʻemaʻe.
ʻO ka hau hau, he laʻana, he kaʻina hana aʻōmole aniani hoʻonaninanililo i pahee a lilo i matte.Hoʻomālamalama ka mālamalama i ka ʻili e hana i ka noʻonoʻo diffuse.I loko o ka hau hau, hoʻoheheʻe ʻia ke aniani me ka emery, ke one silica, ka pauka pomegerane a me nā mea abrasive ʻē aʻe e hana i ka ʻili ʻāwili, a i ʻole ke aniani a me nā mea ʻē aʻe e hiki ke mālama ʻia me kahi solution hydrofluoric acid e hana i ke aniani hau.
Hoʻohana ʻia ka hau a me ka hoʻoneʻe ʻana i ke one e uhi i ka ʻili aniani, no laila e laha like ka mālamalama ma hope o ka hele ʻana i ka pale kukui.He mea paʻakikī i nā mea hoʻohana maʻamau ke hoʻokaʻawale i waena o kēia mau ʻenehana ʻelua.ʻO ka mea ma lalo nei e wehewehe i nā ʻano hana hana o kēia mau ʻenehana ʻelua a pehea e ʻike ai iā lākou.
1. Ka hana hau
ʻO ka hau ka hoʻokomo ʻana i ke aniani i loko o ka wai ʻakika i hoʻomākaukau ʻia (a i ʻole ka hoʻopili ʻana i kahi paʻi waikawa), ka ʻino ʻana i ka ʻili aniani me ka waikawa ikaika, a me ka hydrogen fluoride ammonia i loko o ka waiʻawaʻawa ikaika e hana ai ka ʻili aniani i nā kristal.No laila, inā e hana maikaʻi ʻia ke kaʻina hana hau, ʻoluʻolu loa ka ʻili o ke aniani hau, a hoʻopuka nā kristal i hoʻopuehu ʻia i kahi hopena hazy.Inā 'o'ole'a ka ili, 'o ia ke 'ano o ka 'akika 'ana i ke aniani, a i 'ole kekahi o ia mau mea 'a'ohe kristal.ʻO ka hiʻohiʻona o kēia kaʻina hana ke ʻano 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 mokuʻāina, nui nā mea hana i hana i nā hoʻāʻo a me nā noiʻi he nui, akā ʻaʻole i hiki ke lanakila i kēia pilikia.
2.ʻenehana sandblasting
Hoʻohana ʻo ia i nā ʻāpana one i hoʻokuʻu ʻia e ka pū puhi i ka wikiwiki e paʻi i ka ʻili aniani e hana i kahi ʻili kūpono ʻole, a laila e loaʻa ai ka hopena o ka hoʻopuʻi ʻana i ka mālamalama, a hana i kahi manaʻo pōʻino ke hele ka mālamalama.ʻO ka ʻili o nā huahana aniani i hana ʻia e ke kaʻina hana sandblasting.No ka mea ua poino ka ili o ke aniani, ua like ia me ke aniani keokeo ma ke ano o ka photosensitivity o ke aniani alohilohi mua.
ʻOkoʻa loa nā kaʻina hana ʻelua.ʻOi aku ke kumukūʻai o ke aniani frosted ma mua o ke aniani sandblasted, a hilinaʻi nui ka hopena i nā pono o nā mea hoʻohana.ʻAʻole kūpono kekahi mau aniani kūikawā no ka hau.Ke hoʻoholo nei mai ka ʻimi hanohano, pono e koho ʻia ka matte.Hiki ke hana ʻia ke kaʻina hana sandblasting ma nā hale hana maʻamau, akā ʻaʻole maʻalahi ka hana ʻana i ka sandblasting.
