Hauv tsab xov xwm no, peb yuav tshawb txog kev nyab xeeb ntawm cov hnab ntawv aluminium, cov kev pheej hmoo uas cuam tshuam nrog lawv cov kev siv, thiab cov kev ntsuas uas tuaj yeem siv los txo cov kev pheej hmoo no.
Dab tsi yog aluminium foil hnab?
Aluminium foil hnab yog lub hnab ua los ntawm txhuas ntawv ci, uas yog ib daim ntawv nyias ntawm cov hlau uas tsis tshua muaj siab thiab tuaj yeem ua tau yooj yim khoov, folded lossis zoo li hauv ntau hom. Aluminium ntawv ci hnab tuaj yeem ua ib txheej lossis ntau txheej, nrog rau tom kawg suav nrog cov txheej txheem ntxiv xws li ntawv, yas lossis lwm yam ntaub ntawv. Cov hnab ntim khoom siv feem ntau yog siv rau ntim cov khoom puas tsuaj xws li khoom noj thiab tshuaj, los tiv thaiv lawv ntawm ya raws, roj thiab lub teeb.
Yuav ua li cas yog aluminium foil hnab?
Aluminium foil hnab feem ntau yog ua los ntawm kev sib xyaw ua ke ntawm dov, annealing thiab laminating cov txheej txheem. Cov txheej txheem pib nrog txhuas ingots los yog nplooj ntawv, uas yog dov mus rau hauv nyias cov ntawv ci nrog ib tug xav tau thickness. Lub resulting ntawv ci yog ces annealed, uas yuav tsum tau cua sov cov ntawv ci mus rau ib tug tshwj xeeb kub thiab ces txias nws sai, los txhim kho nws lub zog thiab yooj. Cov ntawv ci yog tom qab ntawd laminated nrog lwm cov ntaub ntawv, xws li yas lossis ntawv, los tsim cov txheej txheem txheej uas muab kev tiv thaiv ntxiv rau cov dej noo, roj thiab lub teeb.
Muaj peev xwm txaus ntshai cuam tshuam nrog txhuas ntawv ci hnab
Muaj ntau qhov kev pheej hmoo uas cuam tshuam nrog kev siv cov hnab ntawv aluminium, tshwj xeeb tshaj yog thaum siv rau ntim khoom noj. Ib qho ntawm cov kev txhawj xeeb tseem ceeb yog lub peev xwm rau txhuas kom nkag mus rau hauv cov zaub mov lossis lwm yam khoom ntawm lub hnab. Aluminium yog cov hlau reactive uas tuaj yeem cuam tshuam nrog cov kua qaub thiab cov ntsev uas muaj nyob hauv cov zaub mov, ua rau muaj cov ntsev txhuas uas tuaj yeem ua rau muaj kev phom sij rau kev noj qab haus huv.
Lwm qhov kev pheej hmoo yog qhov muaj peev xwm kis tau ntawm lub hnab nrog lwm yam tshuaj, xws li cov tshuaj siv hauv kev tsim khoom lossis cov kab mob uas tuaj yeem loj hlob ntawm lub hnab. Qhov no tuaj yeem tshwm sim yog tias lub hnab tsis ua kom tsis muaj menyuam zoo lossis yog tias nws nkag mus rau hauv cov chaw tsis huv thaum lub sijhawm ntim khoom.
Kev ntsuas kom txo qis kev pheej hmoo cuam tshuam nrog aluminium foil hnab
Txawm hais tias muaj peev xwm txaus ntshai cuam tshuam nrog cov hnab ntawv aluminium, muaj ntau yam kev ntsuas uas tuaj yeem coj los txo cov kev pheej hmoo no. Ib qho kev ntsuas tseem ceeb tshaj plaws yog los xyuas kom meej tias cov hnab ntim khoom yog tsim los ntawm cov ntaub ntawv zoo thiab ua kom tsis muaj menyuam ua ntej siv. Qhov no tuaj yeem pab txo qis kev pheej hmoo ntawm kev sib kis nrog lwm yam tshuaj, nrog rau txo qis kev pheej hmoo ntawm txhuas leaching rau hauv cov zaub mov.
Lwm qhov kev ntsuas yog kom tsis txhob siv cov hnab ntawv aluminium rau cov khoom noj acidic lossis qab ntsev, vim tias cov no feem ntau yuav ua rau cov txhuas thiab ua rau leaching. Hloov chaw, nws raug nquahu kom siv lwm cov khoom ntim, xws li iav, ceramic lossis stainless hlau.
Thaum kawg, nws yog ib qho tseem ceeb uas yuav tsum khaws cov hnab ntawv aluminium rau hauv qhov chaw txias, qhuav, deb ntawm tshav ntuj ncaj qha lossis lwm qhov chaw ntawm tshav kub. Qhov no tuaj yeem pab txo qis kev pheej hmoo ntawm oxidation, uas tuaj yeem ua rau cov ntawv ci tawg thiab tso cov txhuas rau hauv cov khoom ntawm lub hnab.
Xaus
Hauv kev xaus, aluminium foil hnab tuaj yeem yog cov khoom ntim khoom siv tau zoo thiab siv tau rau ntau lub hom phiaj. Txawm li cas los xij, muaj peev xwm cuam tshuam nrog lawv cov kev siv, tshwj xeeb tshaj yog thaum siv rau ntim khoom noj. Los ntawm kev siv cov kev ntsuas tsim nyog, xws li siv cov khoom zoo, ua kom tsis muaj menyuam hauv lub hnab kom zoo, tsis txhob noj cov zaub mov acidic lossis qab ntsev thiab khaws cia kom tsim nyog, cov kev pheej hmoo no tuaj yeem txo qis. Raws li nrog rau txhua yam khoom ntim, nws yog ib qho tseem ceeb uas yuav tsum ua tib zoo xav txog cov kev pheej hmoo thiab kev ntsuas tsim nyog los xyuas kom meej qhov kev nyab xeeb ntawm ob qho tib si ntim thiab cov khoom.
