Ka palekana o ka pauka corundum keʻokeʻo i ka polishing ʻana i nā mea lapaʻau
E hele i loko o kekahi mea lapaʻauhoʻowali ʻanahale hana a hiki iā ʻoe ke lohe i ke kani haʻahaʻa o ka mīkini. Ke hana ikaika nei nā limahana i nā lole pale lepo, me nā forceps ʻokiʻoki, nā prostheses hui, a me nā wili niho e ʻālohilohi anuanu ana i ko lākou mau lima - ʻaʻole hiki i kēia mau mea hoʻōla ola ke pale aku i kahi kaʻina hana koʻikoʻi ma mua o ka haʻalele ʻana i ka hale hana: ka wili ʻana. A ʻo ka pauka corundum keʻokeʻo ka "lima kilokilo" pono ʻole i kēia kaʻina hana. Eia nō naʻe, i nā makahiki i hala iho nei, me ka hōʻike ʻia ʻana o kekahi mau hihia o ka pneumoconiosis o nā limahana, ua hoʻomaka ka ʻoihana e nānā hou i ka palekana o kēia pauka keʻokeʻo.
1. No ke aha he mea pono e hoʻopili ʻia nā mea lapaʻau?
No nā huahana "make" e like me nā pahi ʻoki a me nā implants orthopedic, ʻaʻole ka hoʻopau ʻana o ka ʻili he pilikia aesthetic, akā he laina ola a make. Hiki i kahi burr micron ke hōʻino i nā ʻiʻo a i ʻole ka ulu ʻana o ka bacteria.Pauka corundum keʻokeʻo(ʻo ka ʻāpana nui α-Al₂O₃) he "mana paʻakikī" o 9.0 ma ka pae paʻakikī Mohs. Hiki iā ia ke ʻoki pono i nā ʻūpā metala. I ka manawa like, ʻaʻole hoʻohaumia kona mau ʻano keʻokeʻo maʻemaʻe i ka ʻili o ka mea hana. He kūpono loa ia no nā mea lapaʻau e like me ka titanium alloy a me ke kila kila.
Ua ʻōlelo ʻo ʻenekinia Li mai kahi hale hana lako ma Dongguan me ka ʻoiaʻiʻo: "Ua hoʻāʻo mua au i nā mea abrasive ʻē aʻe, akā ua hoʻihoʻi ʻia mai ke koena o ka pauka hao e nā mea kūʻai aku a i ʻole ua haʻahaʻa loa ka pono o ka wili ʻana.ʻO ke korundum keʻokeʻo ʻoki wikiwiki a maʻemaʻe, a ua piʻi pololei ka nui o ka hua ma 12% - ʻaʻole e ʻae nā haukapila i nā prostheses hui me nā ʻōpala." ʻOi aku ka mea nui, ʻaʻole pili iki kona inertness kemika me nā lako. 7. Hōʻalo ia i ka pilikia o ka haumia kemika i hoʻokomo ʻia e ka polishing, he mea nui ia no nā huahana e pili pono ana me ke kino kanaka.
2. Nā hopohopo palekana: ʻo kēlā ʻaoʻao o ka pauka keʻokeʻo
ʻOiai ʻo kēia pauka keʻokeʻo e lawe mai i nā pono o ke kaʻina hana, hūnā pū ia i nā wahi pilikia i hiki ʻole ke hoʻowahāwahā ʻia.
Ka hanu ʻana i ka lepo: ka helu ʻekahi "mea pepehi kanaka ʻike ʻole ʻia"
He maʻalahi loa ke lana ʻana o nā pauka liʻiliʻi me ka nui o nā ʻāpana he 0.5-20 microns. Ua hōʻike ʻia nā ʻikepili mai kahi ʻoihana pale a me ka mālama ʻana i ka hana kūloko i ka makahiki 2023 ua hiki aku ka nui o ka ʻike ʻana o ka pneumoconiosis i waena o nā limahana i hōʻike ʻia i nā nui kiʻekiʻe o ka lepo corundum keʻokeʻo no ka manawa lōʻihi i 5.3%. 2. "I kēlā me kēia lā ma hope o ka hana, aia kahi papa o ka lehu keʻokeʻo i loko o ka pale maka, a he ʻano one ka sputum i ʻū ʻia," wahi a kahi mea hoʻomaʻemaʻe i makemake ʻole e kapa ʻia. ʻO ka mea paʻakikī loa, hiki i ka manawa hoʻoulu o ka pneumoconiosis ke lōʻihi a hiki i nā makahiki he ʻumi. He akahai nā hōʻailona mua akā hiki ke hōʻino mau i ka ʻiʻo o ka māmā.
ʻIli a me nā maka: ke kumukūʻai o ka hoʻopili pololei ʻana
He ʻoi nā ʻāpana micropowder a hiki ke hoʻoulu i ka maneʻo a i ʻole nā ʻōpala ke kau lākou ma ka ʻili; ke komo lākou i loko o nā maka, hiki iā lākou ke ʻōpala maʻalahi i ka cornea. 3. Ua hōʻike ʻia kahi hōʻike ulia pōpilikia mai kahi hale hana OEM kaulana i ka makahiki 2024 ma muli o ka ʻelemakule ʻana o ke sila goggles pale, ua komo ka lepo i loko o nā maka o kahi limahana i ka wā e hoʻololi ai i ka abrasive, e hopena ana i nā ʻōpala corneal a me ka pani ʻana o ʻelua pule.
Ke aka o ke koena kemika?
ʻOiai ʻo ka corundum keʻokeʻo ponoʻī he paʻa kemika, hiki i nā huahana haʻahaʻa ke loaʻa nā metala kaumaha inā loaʻa iā lākou ka sodium kiʻekiʻe (Na₂O>0.3%) a ʻaʻole i hoʻomoʻa pono ʻia. 56. Ua ʻike kekahi keʻena hoʻāʻo i ka 0.08% Fe₂O₃6 i loko o kahi pūʻulu corundum keʻokeʻo i kapa ʻia "pae lapaʻau" - he mea huna kēia no nā stent puʻuwai e pono ai ka biocompatibility piha.
3. Ka pale ʻana i ka pilikia: e kau i ka "pauda weliweli" i loko o kahi pā
ʻOiai ʻaʻole hiki ke hoʻololi piha ʻia, ʻo ke kāohi ʻepekema a me ka kaohi wale nō ke ala e puka ai. Ua ʻimi nā ʻoihana alakaʻi i ka ʻoihana i nā "laka palekana" he nui.
Ka mana ʻenekinia: Pepehi i ka lepo ma ke kumu
Ke piʻi wikiwiki nei ka kaulana o ka ʻenehana poli pulu - ke kāwili ʻana i ka pauka liʻiliʻi me ka hopena wai i loko o ka paʻi wili, ua emi ka nui o ka lepo i hoʻokuʻu ʻia ma mua o 90%. 6. Ua hana ka luna hana o kahi hale hana prosthesis hui ma Shenzhen i ka makemakika: "Ma hope o ka hoʻololi ʻana i ka wili pulu, ua hoʻolōʻihi ʻia ke kaʻina hana hoʻololi o ka kānana peʻahi ea hou mai 1 pule a i 3 mahina. Me he mea lā he 300,000 ke kumukūʻai o nā lako, akā ʻo ka uku maʻi hana i mālama ʻia a me nā pohō hoʻokuʻu hana e uku no lākou iho i loko o ʻelua mau makahiki." ʻO ka ʻōnaehana hoʻopau kūloko i hui pū ʻia me ka papa hana kaomi maikaʻi ʻole hiki ke pale hou aku i ka lepo e pakele ana2.
Ka palekana pilikino: ka laina hope loa o ka pale kaua
ʻO nā pale lepo N95, nā aniani pale i hoʻopaʻa piha ʻia, a me nā jumpsuit anti-static nā lako maʻamau no nā limahana. Akā ʻo ka paʻakikī o ka hoʻokō ʻana aia ma ka hoʻokō ʻana - ʻoi aku ka mahana o ka hale hana ma mua o 35℃ i ke kauwela, a wehe malū pinepine nā limahana i kā lākou mau pale maka. No kēia kumu, ua hoʻolauna kahi hale hana ma Suzhou i kahi mea hanu akamai me kahi peʻahi micro, kahi e noʻonoʻo ai i ka pale a me ka hanu ʻana, a ua emi nui ka nui o ka uhaki.
Hoʻonui mea: ua hānau ʻia ka pauka micro palekana
ʻO ka hanauna hou o nā lāʻau lapaʻau haʻahaʻa-sodiumcorundum keʻokeʻo(ʻO Na₂O<0.1%) he emi nā haumia a ʻoi aku ka nui o ka hoʻolaha ʻana o nā ʻāpana i hoʻopaʻa ʻia ma o ka pickling hohonu a me ka hoʻokaʻawale ʻana o ke kahe ʻana o ka ea. 56. Ua hōʻike ke alakaʻi loea o kahi hui abrasive ma ka moku ʻo Henan i kahi hoʻokolohua hoʻohālikelike: ua ʻike ʻia he 2.3μg/cm² o ke koena alumini ma luna o ka ʻili o ka mea hana ma hope o ka wili ʻana me ka pauka micro kuʻuna, ʻoiai ʻo ka huahana haʻahaʻa-sodium he 0.7μg/cm² wale nō, ma lalo loa o ka palena maʻamau ISO 10993.
Ke kūlana opauka micro corundum keʻokeʻoma ke kahua o ka hoʻopili ʻana i nā mea lapaʻau e paʻakikī ke hoʻoluliluli i ka wā pōkole. Akā, ʻaʻole ia he mea kūlohelohe kona palekana, akā, he hoʻokūkū mau ma waena o ka ʻenehana mea, ka mana ʻenekinia a me ka hoʻokele kanaka. Ke hopu ʻia ka lepo manuahi hope loa ma ka hale hana, i ka wā e pau ai ka ʻili laumania o kēlā me kēia mea hana ʻoki kino i ke olakino o nā limahana - paʻa maoli mākou i ke kī i ka "hoʻopili palekana". Ma hope o nā mea a pau, pono e hoʻomaka ka maʻemaʻe o ka mālama ʻana mai ke kaʻina hana mua o ka hana ʻana.
