Qhov twg Medicinal Aluminium Foil siv
Pharmaceutical ntim yog qhov xav tau tshaj plaws rau daim ntawv nyias nyias. Cov khoom siv yog siv rau blister lidding ntawm cov ntsiav tshuaj thiab tshuaj ntsiav packs, rau strip ntim, rau sachets tuav hmoov thiab granules, thiab raws li cov txhuas txheej nyob rau hauv txias - tsim blister bases thiab laminated hlab. Vim hais tias cov ntawv ci yog nyob rau hauv kev sib cuag nrog cov tshuaj, nws cov tsos thiab kev ua tau zoo yog tswj nyob deb ntau nruj tshaj nyob rau hauv cov zaub mov ntim: ya raws barrier, lub teeb barrier, tshuaj inertness thiab huv si huv si yog cov yuav tsum tau ua hauj lwm es tsis nyiam cosmetic nyiam.
Ob lub alloys ua lag luam, 8011 thiab 8021, ob qho tib si xa hauv cov mos mos annealed O temper thiab ob qho tib si tsis muaj tooj liab thiab magnesium ntxiv kom lawv nyob twj ywm tsis muaj zog thiab lees txais luam ntawv, lacquer thiab cua sov- foob txheej tsis muaj tshuaj tiv thaiv.
8011 thiab 8021: Yam khoom twg rau pob
| Alloy | Kev tsom xam | Hom gauge ntau yam | Hom kev siv |
|---|---|---|---|
| 8011 | 0.50-0.90%, Fe 0.60-1.00%, tshuav nyiaj li cas | 0.020-0.050 hli | Blister hau ntawv ci, strip thiab sachet packing, tshav kub- foob lacquer puag |
| 8021 | Ntau cov hlau txheeb ze rau silicon, muab cov ntawv tawv tawv thiab muaj zog dua | 0.030-0.090 hli | Txias-cov ntaub ntawv hauv paus webs, sib sib zog nqus nqus blister hom, laminated qauv |
Lub tswv yim sib txawv ntawm ob yog txhua yam es tsis yog tshuaj. Cov qib hlau siab dua hauv 8021 nce lub zog thiab nruj, uas yog qhov xav tau ntawm cov ntawv ci thaum nws yuav tsum muaj sia nyob sib sib zog nqus nqus hauv qhov txias - daim ntawv laminate. Lub softer 8011 yog kev lag luam ntau dua thiab yog cov neeg ua haujlwm rau cov ntawv ci uas tau luam tawm, lacquered thiab tom qab ntawd kub kaw rau hauv lub qhov ncauj kab noj hniav.
Txoj kev tsim khoom los ntawm Blank mus rau Coil tiav
Cov txheej txheem txheej txheem ntws yog kev tshuaj xyuas dawb paug, npliag dov, sib cais dov, ua ke coil dov, dov khoom, slitting, cub annealing thiab tiav cov khoom ntim. Txhua kauj ruam nqa nws tus kheej tswj, thiab qhov kawg ntawm cov ntawv ci yog txiav txim siab ntev ua ntej qhov kawg dhau.
Kev kuaj dawb- Cov khoom cam khwb cia tuaj tau raug kuaj xyuas cov ntsiab lus suav nrog, qhov tsis xws luag, ntug zoo thiab chemistry ua ntej nws nkag mus rau hauv lub zeb.
Rolling- ntawv ci yog dov los ntawm roughing, nruab nrab thiab tiav dhau, thiab nyob rau hauv qhov kawg hla ob nplooj ntawv yog dov ua ke, uas muab ib tug kaj tiav rau ntawm lub ntsej muag thiab ib tug matte tiav nyob rau hauv lub puab lub ntsej muag.
Slitting- coils raug txiav mus rau qhov dav txiav txim siab nrog cov npoo huv thiab tswj cov kab nrib pleb, vim hais tias ib qho wrinkled lossis burred ntug hloov mus ncaj nraim mus rau hauv cov dej tsis raug.
Annealing- lub kauj yog annealed rau O temper kom tshem tawm cov roj dov thiab rov qab ductility, nrog rau qhov kub thiab txias lub sij hawm teem los ntawm kev ua tau zoo ntawm cov khoom tiav.
Surface Quality Requirements for Pharmaceutical Foil
Cov ntawv ci tshuaj yuav tsum tsis pub dawb los ntawm cov roj stains, ci siv lead ua thiab coarse grain, cov kab dub, daj me ntsis, ntug wrinkles thiab pinholes tshaj qhov txwv. Pinholes tsim nyog tau txais kev saib xyuas tshwj xeeb: ntawm 0.020 mm thickness ib zaug los ntawm pinhole muab txoj hauv kev ncaj qha rau cov dej noo thiab oxygen rau hauv lub hlwv kab noj hniav, yog li tus pinhole suav raug kho raws li cov txheej txheem tso tawm ntau dua li qhov tsis pom kev, thiab nws yog ntsuas tshaj thaj tsam ntawm lub kauj.
Txheej txheem tswj cov ntsiab lus uas txiav txim siab foil zoo
Qhov chaw tswj- metallurgical huv huv ntawm cov cam khwb cia Tshuag yog qhov loj tshaj plaws ib qho kev txiav txim ntawm pinhole zaus, vim dov - hauv oxides thiab inclusions tsis tuaj yeem raug tshem tawm los ntawm kev ua haujlwm tom qab.
Roll condition- roughness, yas thiab huv si ntawm kev ua hauj lwm yob tswj cov tsos thiab cov uniformity ntawm thickness thoob plaws qhov dav.
Rolling roj- viscosity, additive pob thiab filtration txiav txim siab roj phaj- tawm; qis dua -cov roj viscosity ua ke nrog lub tshuab tswj ceev kom txo cov roj nqa- dhau thiab txwv qhov kub thiab txias tsim- nce.
Ceev thiab nro- ruaj khov nro tiv thaiv chatter marks, thickness excursions thiab slack npoo.
Slitting zoo- rab riam ntse teem rau qhov tseeb sib tshooj muab cov npoo ncaj tsis muaj folds lossis burrs.
Annealing- soak kub thiab lub sij hawm yuav tsum tau ua kom haum rau cov tshuaj thiab txhua yam yuav tsum tau ntawm cov ntawv ci, ua kom tiav cov roj tshem tawm yam tsis muaj tshaj - softening los yog grain coarsening.
Cov qauv, Kev huv huv thiab kev taug qab
Pharmaceutical foil raug tso tawm tawm tsam cov txheej txheem ntim tshuaj siv ua ke nrog cov ntawv qhia dav dav txhuas, piv txwv li GB / T 3198 series rau wrought aluminium foil thiab YBB series ntawm cov qauv rau cov khoom ntim tshuaj. Nws yog tus qauv, tsis yog qhov pom kev pom ntawm lub kauj, uas txhais cov thickness kam rau ua, suav pinhole, qhov chaw txwv, tsim tus cwj pwm thiab lacquer adhesion. Kev tsim khoom yog ib txwm ua raws li cov ntaub ntawv pov thawj zoo hauv kev tswj hwm -ib puag ncig kev cob qhia, nrog rau kev taug qab los ntawm tus lej cam khwb cia kom tiav pallet kom txhua qhov sib txawv tuaj yeem raug cais tawm sai.
Kev loj hlob ntawm cov kws kho mob txuas ntxiv thawb cov neeg tsim khoom ntawm cov ntawv ci rau cov khoom siv thinner, nruj dua thickness tolerances thiab qis pinhole suav, vim hais tias txhua qhov txo cov ntawv ci thickness txhim kho cov khoom yield rau lub packer thaum xav tau zoo melting, casting thiab dov tswj los ntawm lub zeb.
Cov lus nug nquag
Q: Dab tsi yog tshuaj kho mob aluminium foil siv rau?
Nws yog siv rau blister lidding ntawm ntsiav tshuaj thiab tsiav tshuaj, rau strip packs thiab sachets uas muaj hmoov los yog granules, thiab raws li cov txhuas txheej nyob rau hauv txias - tsim blister bases thiab laminated hlab.
Q: Qhov txawv ntawm 8011 thiab 8021 ntawv ci yog dab tsi?
Ob leeg yog Al-Fe-Si alloys tsis muaj tooj liab lossis magnesium. 8011 yog softer thiab feem ntau yog siv los luam thiab lacquered lidding ntawv ci, thaum 8021 muaj ntau hlau, muab ntau zog thiab nruj rau sib sib zog nqus nqus txias- daim ntawv thov.
Q: Dab tsi thickness yog siv rau tshuaj blister foil?
Lidding ntawv ci feem ntau yog 0.020-0.030 hli, thaum lub caij txias-daim ntawv lub hauv paus webs thiab cov ntawv ntim hnyav dua siv cov ntsuas ntawm li 0.030 hli mus txog 0.090 hli, nrog rau qhov ntsuas qhov tseeb los ntawm tus qauv ntim thiab lub tshuab filling.
Q: Vim li cas pinholes thiaj li tseem ceeb hauv cov ntawv ci tshuaj?
Ib tug pinhole tsim ib qho ncaj qha ya raws thiab oxygen txoj hauv kev los ntawm txheej txheej barrier. Txij li cov ntawv ci feem ntau tsuas yog 0.020 hli tuab, pinhole suav yog qhov ua haujlwm tso tawm thiab tswj los ntawm kev ua kom huv si, yob nto zoo thiab ruaj khov nro.
Q: Yuav ua li cas dov roj tshem tawm ntawm cov ntawv ci?
Los ntawm qhov cub annealing. Kub thiab ntub lub sij hawm yog teem kom cov roj residual yog tag nrho evaporated thiab decomposed yam tsis softening cov ntawv ci ntau dhau los yog coarsening nws grain qauv.
Q: Qhov twg tempers tau muab?
Pharmaceutical foil yuav luag ib txwm muab nkag rau hauv cov mos mos annealed O temper, vim lacquering, luam ntawv thiab kub sealing tag nrho yuav tsum tau ib tug ductile, dimensionally ruaj khov substrate.
