Nā Koi Hygienic no ka White Corundum i nā Lako Hana Meaʻai
I ka hola ʻelima o ke kakahiaka, ua hāwanawana ʻo Luna Hoʻokele Li o ka hale hana i kona wehe ʻana i ka puka o ka hale hana, me kahi ʻala ikaika o ka mea hoʻomaʻemaʻe ozone e pā ana iā ia. E like me ka mea maʻamau, ua hele ʻo ia i ka mea hoʻoheheʻe wai wili hou i hoʻokomo ʻia, me kona mau manamana lima e palaki ana i ka loko kila kila, kahi i like me ka laumania o ke aniani. "E Old Wang, he mea maikaʻi loa kēia mea hoʻomaʻemaʻe hou! ʻOi aku ka maikaʻi ma mua o ka pūʻulu hope loa. ʻAʻohe ʻāpana burr hoʻokahi i ka pā!" Ua ʻakaʻaka ʻo Operator Old Wang. "ʻOiaʻiʻo, ʻo nā ʻauwaha i hana ʻia e kēia 'pauka sapphire keʻokeʻo' e hoʻolilo i ke koena hua i laumania e like me ka loach. He kakaikahi nā kihi haumia!" ʻO kēia "pauka sapphire keʻokeʻo" haʻahaʻa a lākou e ʻōlelo nei ʻo ia ka mea nui e mālama ai i ke ola maʻemaʻe o nā lako hana meaʻai: ka papa meaʻaicorundum keʻokeʻo.
I ke ao o ka hana ʻana i ka meaʻai, he mea nui loa ka "hoʻomaʻemaʻe". ʻOiai ka ʻōpala liʻiliʻi a i ʻole ka lua ma luna o nā lako hana hiki ke lilo i wahi hānau no ka bacteria a hiki i ka hūnā ʻana i nā ʻōpala metala, e hoʻohaumia ana i ka huahana. ʻO ka pauka corundum keʻokeʻo papa meaʻai ka "mea kaua paʻakikī" e lanakila ai i kēia pilikia. Hana ʻia ia mai ka alumina maʻemaʻe kiʻekiʻe (Al₂O₃ ≥ 99.5%), hoʻoheheʻe ʻia i loko o ka umu arc uila, hoʻomaʻalili ʻia a hoʻoheheʻe ʻia, a laila kuʻi ʻia a hoʻokaʻawale ʻia. He paʻakikī Mohs a hiki i ka 9. Eia nō naʻe, ʻoi aku ka paʻakikī o nā koi papa meaʻai ma mua o ka "paʻakikī" wale nō; hoʻoikaika pū lākou i ka "maʻemaʻe" a me ka "maʻemaʻe."
ʻO ka maʻemaʻe ke ola o ka palekana o ka meaʻai. Hiki i ka corundum keʻokeʻo ʻoihana maʻamau ke mālama i nā ʻāpana liʻiliʻi o nā haumia metala e like me ka hao a me ka chromium. I loko o ka ʻoihana hana meaʻai, ʻoiai he hapa o hoʻokahi hapa no ka miliona hiki ke lilo i mea pōʻino. Hoʻomanaʻo wau i kahi hale hana wai kūloko ʻekolu mau makahiki i hala aku nei i loaʻa i kahi hanana kahi i ʻike ʻia ai nā pae kiʻekiʻe o nā metala kaumaha i kāna mau huahana. ʻO ke kumu ka hoʻohana ʻana i nā mea abrasives i loaʻa ka hao i ka wā e hoʻopili ʻia ai. Ua komo kēia mau ʻāpana metala i loko o nā ʻūmiʻi weld a ua hoʻoheheʻe ʻia e ka wai waikawa i ka hala ʻana o ka manawa. Hoʻopau ka corundum keʻokeʻo papa meaʻai i kēia mau pilikia mai ke kumu: nā mea maka i koho pono ʻia, ʻaʻohe haumia o ke kaiapuni hoʻoheheʻe, a ua hele ka huahana i hoʻopau ʻia i ka hoʻāʻo ʻana o ICP-MS (Inductively Coupled Plasma Mass Spectrometry) e hōʻoia i ka noho ʻana o ka ʻike metala kaumaha ma lalo o nā palena paʻa i hoʻonohonoho ʻia e ke kūlana aupuni GB 4806.9-2016, "Nā Mea Metala a me nā ʻatikala i manaʻo ʻia no ka hoʻopili ʻana i ka meaʻai." Ma nā ʻōlelo a Lao Zhang mai ka ʻOihana Nānā Kūlana, "He maʻemaʻe loa kēia pauka, ua like ia me ka hoʻohana ʻana iā ia ma ke ʻano he scanner palekana no nā lako. Pono ʻoe e 'maʻemaʻe' iā ʻoe iho ma mua!"
ʻO ke ʻano o nā ʻāpana e hoʻoholo ai i ke ola ʻana o nā wahi makapō maʻemaʻe. ʻAʻole pili ka hoʻopili ʻana i nā lako meaʻai i ka "ʻālohilohi" ʻoi aku ka maikaʻi; ʻo ke kī ka hana ʻana i kahi ʻili ʻaʻole i hūnā i ka lepo. E noʻonoʻo i kahi pahu hui kila kila. Hoʻopili ʻia me nā mea abrasives maʻamau me nā ʻaoʻao ʻoi, ʻike ʻia he ʻālohilohi, akā ma lalo o kahi microscope, ua piha ia me nā "grooves microscopic" - nā wahi kūlohelohe no ka bacteria a me nā koena. Hoʻohana ka micropowder corundum keʻokeʻo meaʻai i kahi kaʻina hana hoʻohālikelike kūikawā e hana i nā ʻāpana kokoke i ka poepoe. E like me ka wehewehe ʻana a Lao Wang, "Ua hoʻohana au i ka pauka brand ʻole, a ʻo nā lako ma hope o ka hoʻopili ʻana ua like ia me ke aniani hau - laumania i ka pā, akā piha i nā lua liʻiliʻi ma ka nānā pono ʻana. I kēia manawa, me kēia pauka poepoe, ua like ia me ke aniani maoli! E holoi me ka wai, a ʻaʻohe mea e pipili i ka ʻili. " Hoʻopili like ʻia nā ʻāpana poepoe i ka wā o ka hoʻopili ʻana, ma mua o ka ʻoki ʻana, e hoʻemi ana i nā microcracks a me nā lua, e hoʻolilo ana i ka ʻili o nā lako i "maʻalahi e hoʻomaʻemaʻe a ʻaʻohe koena."
Kūkulu ka mālama ʻili i kahi pale microbial. ʻO ke kiʻekiʻe o ka mahana a me ka haʻahaʻa o nā hale hana meaʻai e hana i kahi puʻuhonua no ka ulu ʻana o ka microbial. ʻOiai he paʻa maoli ka pauka corundum keʻokeʻo maʻamau, hiki iā ia ke lilo i kumu o ka haumia inā omo ia i ka makū a i ʻole nā mea haumia organik. Pono nā huahana papa meaʻai e hana i nā lāʻau passivation kūikawā a me nā pore sealing: hoʻopau ka calcination wela kiʻekiʻe i nā wahi hana o ka ʻili, a laila uhi ʻia nā ʻāpana me kahi uhi silane papa meaʻai. ʻAʻole wale kēia "uhi pale" e pale i ka abrasive mai ka omo ʻana i nā mea haumia o ke kaiapuni, akā hōʻoia pū kekahi i ka hoʻolaha like a paʻa i loko o ka slurry polishing. Ua kaʻana like kekahi ʻenekinia ma kahi hale hana waiū, "Ma hope o ka hoʻololi ʻana i ka mālama ʻiapauka corundum keʻokeʻo, ua piʻi aʻe ka helu ʻae no nā nānā ʻana i nā microbial ma hope o ka holoi ʻana i nā lako ma 30%. Ua like ia me ka hoʻopili ʻana i kahi papa o ka 'wax' i ka ʻili o nā lako, e pale ana i ka lepo mai ka noho ʻana!
ʻO ka ʻenehana hana a me ke kaʻina hana hoʻomaʻemaʻe paʻa. ʻOi aku ka hoʻohana ʻana i ka corundum keʻokeʻo i nā lako meaʻai ma mua o kahi hana maʻalahi o ka lepo a me ka polishing. Mai ka polishing welds i loko o nā pahu hui a hiki i nā ʻōmole kokoleka hoʻopau aniani, pono e mālama ʻia nā kūlana hoʻomaʻemaʻe "ʻaʻohe lepo, ʻaʻohe ʻaila, a hiki ke hahai ʻia". Pono e hana ʻia ka polishing ma kahi maʻemaʻe a kaʻawale me ka hoʻohana ʻana i kahi lubricant hoʻoluʻu papa meaʻai (ʻo ka wai deionized maʻamau a i ʻole ka ʻaila mea kanu i hoʻomaʻemaʻe ʻia) e pale aku i ka haumia o ka ʻaila mineral. Ma hope o ka polishing, hele nā lako i kahi kaʻina hana hoʻomaʻemaʻe multi-stage: alkaline degreasing, acid passivation, a ʻo ka hope loa ka holoi ʻana i ka wai maʻemaʻe a hiki i ka conductivity i ka pae i kuhikuhi ʻia. Ua like ke kaʻina hana holoʻokoʻa me ke kaʻina hana ʻoki kino, me kēlā me kēia ʻanuʻu i hoʻopaʻa ʻia. Hoʻokahi mea hana meaʻai hau e hoʻokuʻu aku ana i ka EU e kauoha ana i kahi pae hoʻomaʻemaʻe ea Class 100,000 ma ka hale hana polishing - ʻo kēia pauka corundum keʻokeʻo e "hula maoli ana i loko o kahi lumi sterile."
I ka nānā ʻana i mua, e lilo ana nā koi hoʻomaʻemaʻe a me ka palekana o ka ʻoihana meaʻai i mea paʻakikī loa. E lilo ka nānā akamai ʻana ma ka pūnaewele i mea maʻamau. No ka laʻana, hiki i nā slurries polishing corundum keʻokeʻo me nā sensor i hoʻohui ʻia ke nānā i ka pH, ka nui o nā ʻāpana, a me ka nui o ka haumia i ka manawa maoli; a hiki ke hoʻomohala ʻia ka corundum keʻokeʻo i hoʻololi ʻia me nā uhi antimicrobial e hāʻawi i nā waiwai antibacterial i nā ʻili o nā lako i ka wā e polishing ai. Ua ʻōlelo mua ʻo Kauka Wu, he loea meaʻai, "ʻO ka ulu ʻana o ka corundum keʻokeʻo papa meaʻai he kaua microscopic e kūʻē i ka haumia microbial a me ka neʻe ʻana o nā kemika. ʻOi aku ia ma mua o ka abrasive wale nō; ʻo ia ka pale kino mua i ka palekana o ka meaʻai."
Ke ʻālohilohi like kahi ʻauwai kila kila ma lalo o ke kukui, ke puka mai ka kokoleka mai kona ʻōmole me kahi ʻano aniani kūpono, ke holoi ʻia kahi laina hoʻopiha wai huaʻai me ke kaomi kiʻekiʻe a ʻaʻole ʻike i kahi koena microbial—ma hope o ia mea āpau e waiho ana ka micropowder corundum keʻokeʻo papa meaʻai, e hoʻopaʻa mālie ana i kāna ʻōlelo hoʻohiki o ka "paʻakikī, maʻemaʻe, a me ka maʻemaʻe." ʻAʻohe ona ʻālohilohi kupaianaha, akā me kona ikaika paʻa ʻole a me kona ʻano maʻemaʻe, kūkulu ia i kahi pā pale ʻike ʻole ʻia ma kahi koʻikoʻi kahi e hui ai nā mīkini me ka meaʻai, e mālama ana i ka palekana o ko kākou mau alelo.
I ke ao o ka hana ʻana i ka meaʻai, hoʻomaka pinepine nā kūlana hoʻomaʻemaʻe koʻikoʻi loa me ka pae ʻike ʻole ʻia o ka laumania.
