Ukhuseleko lomgubo omhlophe we-corundum ekupholiseni izixhobo zonyango
Ngena nakwesiphi na isixhobo sezonyangoukupolishaKwiworkshop kwaye unokuva isandi esiphantsi somatshini. Abasebenzi abanxibe iisuti ezingangeni uthuli basebenza nzima, bephethe ii-forceps zotyando, ii-prostheses ezidibeneyo, kunye nee-drill zamazinyo ezikhazimlayo ezandleni zabo - ezi zixhobo zisindisa ubomi azinakuphepha inkqubo ephambili ngaphambi kokuba ziphume kumzi-mveliso: ukupolisha. Kwaye umgubo we-corundum omhlophe "sisandla somlingo" esibalulekileyo kule nkqubo. Nangona kunjalo, kwiminyaka yakutshanje, ngokubonakala kwamatyala aliqela e-pneumoconiosis yabasebenzi, eli shishini liqalise ukuphinda lihlolisise ukhuseleko lwalo mgubo umhlophe.
1. Kutheni kuyimfuneko ukupolisha izixhobo zonyango?
Kwiimveliso "ezibulalayo" ezinje ngeeblade zotyando kunye nee-orthopedic implants, ukugqitywa komphezulu akuyongxaki yobuhle, kodwa ngumgca wobomi nokufa. I-burr enobukhulu be-micron inokubangela umonakalo kwizicubu okanye ukukhula kwebhaktheriya.Umgubo omncinci we-corundum omhlophe(inxalenye ephambili ye-α-Al₂O₃) inamandla aqinileyo e-9.0 kwisikali sobunzima be-Mohs. Ingasika ngokufanelekileyo ii-metal burrs. Kwangaxeshanye, iimpawu zayo ezimhlophe azingcolisi umphezulu wento yokusebenza. Ifanelekile ngokukodwa kwizixhobo zonyango ezifana ne-titanium alloy kunye nentsimbi engatyiwayo.
Unjineli uLi ovela kumzi-mveliso othile wezixhobo eDongguan uthe ngokunyaniseka: “Ndikhe ndazama ezinye izinto zokurhawuzelela ngaphambili, kodwa nokuba umgubo wesinyithi oseleyo ubuyiselwe ngabathengi okanye ukusebenza kakuhle kokupholisha bekuphantsi kakhulu.I-corundum emhlophe Inqunyulwa ngokukhawuleza nangokucocekileyo, kwaye izinga lemveliso linyuke ngokuthe ngqo nge-12% - izibhedlele aziyi kwamkela ii-prostheses zamalungu ezinemikrwelo.” Okubaluleke ngakumbi, ukungangeni kwayo kwiikhemikhali akwenzeki kangako xa kusetyenziswa izixhobo. 7. Iyayiphepha ingozi yokungcoliswa ziikhemikhali eziziswa kukupolisha, nto leyo ibalulekileyo kwiimveliso ezidibana ngqo nomzimba womntu.
2. Iingxaki zokhuseleko: icala elingaphandle lomgubo omhlophe
Nangona le mpuphu emhlophe izisa iingenelo zenkqubo, ikwafihla neendawo zomngcipheko ezingenakubethwa ngoyaba.
Ukuphefumla uthuli: "umbulali ongabonakaliyo" oyintloko
Iipowder ezincinci ezinobukhulu bee-microns eziyi-0.5-20 kulula kakhulu ukuzidada. Idatha evela kwiziko lokuthintela nonyango lomsebenzi lasekuhlaleni ngo-2023 ibonise ukuba izinga lokubhaqwa kwe-pneumoconiosis phakathi kwabasebenzi ababechaphazeleka kubuninzi bothuli olumhlophe lwe-corundum ixesha elide lifikelele kwi-5.3%. 2. “Yonke imihla emva komsebenzi, kukho umaleko wothuthu olumhlophe kwimaski, kwaye isikhwehlela esikhohliwe sinobume besanti,” utshilo umpolishi ongafuni ukubizwa ngegama. Okunzima ngakumbi kukuba ixesha lokufakelwa kwe-pneumoconiosis linokuba yiminyaka elishumi. Iimpawu zokuqala zincinci kodwa zingonakalisa ngokungenakulungiseka izicubu zemiphunga.
Ulusu namehlo: ixabiso lokunxibelelana ngqo
Amasuntswana e-micropowder abukhali kwaye anokubangela ukurhawuzelela okanye ukukrwela xa efika eluswini; xa efika emehlweni, anokuyikrwela lula i-cornea. 3. Ingxelo yengozi evela kumzi-mveliso wezixhobo ze-OEM owaziwayo ngo-2024 ibonise ukuba ngenxa yokuguga kwesitywina seeglasi zokukhusela, umsebenzi wafaka uthuli emehlweni akhe xa etshintsha i-abrasive, nto leyo eyabangela ukukrweleka kwe-cornea kunye nokuvalwa kweeveki ezimbini.
Isithunzi sentsalela yeekhemikhali?
Nangona i-corundum emhlophe ngokwayo izinzile ngokweekhemikhali, iimveliso ezikumgangatho ophantsi zinokuba nee-trace metals ezisindayo ukuba ziqulethe i-sodium ephezulu (Na₂O>0.3%) okanye azifakwanga kakuhle. 56. I-arhente yovavanyo yakha yafumanisa i-0.08% Fe₂O₃6 kwiqela le-corundum emhlophe ebhalwe "ibanga lezonyango" - ngokungathandabuzekiyo le yingozi efihlakeleyo kwi-stents zentliziyo ezifuna ukuhambelana ngokupheleleyo.
3. Ulawulo lomngcipheko: faka "umgubo oyingozi" kwikheyiji
Ekubeni ingenakutshintshwa ngokupheleleyo, ukuthintela nokulawula ngokwesayensi yeyona ndlela yokuphuma. Iinkampani eziphambili kushishino ziye zahlola "ii-safety lock" ezininzi.
Ulawulo lobunjineli: Bulala uthuli kwindawo ephuma kuyo
Itekhnoloji yokupolisha ngomanzi iyanda ngokukhawuleza – ukuxuba umgubo omncinci kunye nesisombululo samanzi kwi-grinding paste, ubungakanani bokukhupha uthuli buncipha ngaphezulu kwe-90%6. Umlawuli weworkshop yefektri edibeneyo yokufakelwa eShenzhen wenza izibalo: “Emva kokutshintshela ekugayeni ngomanzi, umjikelo wokutshintsha isihluzi sefeni yomoya omtsha wolulwe ukusuka kwiveki e-1 ukuya kwiinyanga ezi-3. Kubonakala ngathi izixhobo zibiza kakhulu ngama-300,000, kodwa imbuyekezo yezifo zomsebenzi kunye nelahleko yokumiswa kwemveliso iya kuzihlawulela kwiminyaka emibini.” Inkqubo yokukhupha umoya yasekuhlaleni kunye netafile yokusebenza yoxinzelelo olubi inokuthintela ngakumbi uthuli oluphumayo2.
Ukhuseleko lomntu: umgca wokugqibela wokuzikhusela
Iimaski zothuli ze-N95, iiglasi zokukhusela ezivalekileyo ngokupheleleyo, kunye neesuti zokujija ezingashukumiyo zizixhobo eziqhelekileyo zabasebenzi. Kodwa ubunzima bokusetyenziswa buxhomekeke ekuthobeleni imithetho - ubushushu beworkshop budlula i-35℃ ehlotyeni, kwaye abasebenzi badla ngokuzikhulula iimaski zabo ngasese. Ngenxa yesi sizathu, umzi-mveliso eSuzhou wazisa isixhobo sokuphefumla esikrelekrele esinefeni encinci, esiqwalasela ukhuseleko kunye nokuphefumla, kwaye izinga lokwaphulwa komthetho lehle kakhulu.
Ukuphuculwa kwezinto: umgubo omncinci okhuselekileyo uzalwa
Isizukulwana esitsha sezonyango ezinesodium ephantsii-corundum emhlophe(Na₂O<0.1%) inokungcola okuncinci kwaye isasazwa ngobukhulu beesuntswana ezixineneyo ngokusebenzisa ukucola okunzulu kunye nokuhlelwa komoya. 56. Umlawuli wezobugcisa wenkampani erhabaxa kwiPhondo laseHenan ubonise uvavanyo oluthelekisayo: i-2.3μg/cm² yentsalela ye-aluminiyam ifunyenwe kumphezulu wesixhobo emva kokupolisha nge-micro powder yendabuko, ngelixa imveliso ene-sodium ephantsi yayiyi-0.7μg/cm² kuphela, engaphantsi kakhulu komda oqhelekileyo we-ISO 10993.
Isikhundla sikaumgubo omncinci we-corundum emhlophekwicandelo lokupholisha izixhobo zonyango kuya kuhlala kunzima ukulishukumisa kwixesha elifutshane. Kodwa ukhuseleko lwayo aluyonto yangaphakathi, kodwa lukhuphiswano oluqhubekayo phakathi kobuchwepheshe bezinto, ulawulo lobunjineli kunye nolawulo lwabantu. Xa uthuli lokugqibela olukhululekileyo kwindawo yokusebenzela lubanjwa, xa umphezulu ogudileyo wesixhobo ngasinye sotyando ungasasebenzi kwimpilo yabasebenzi – sibambe isitshixo “sokupholisha ngokukhuselekileyo”. Kaloku, ubunyulu bonyango kufuneka buqale kwinkqubo yokuqala yokulwenza.
