Pharmaceutical Aluminium Foil thiab Dab tsi Ua rau Nws txawv
Pharmaceutical aluminium foil yog ib qho ntawm cov ntawv ci tshaj plaws hauv kev siv txhua hnub. Nws lub luag haujlwm tseem ceeb yog ntim ntim rau cov tshuaj ntsiav thiab ntsiav tshuaj thiab lub hnab ntim rau cov hmoov granules thiab kua. Vim tias cov ntawv ci tuaj rau hauv kev sib cuag ncaj qha nrog cov tshuaj uas tau noj hauv qhov ncauj, cov kev cai tswj hwm ntawm ob qho tib si tsos thiab kev ua tau zoo yog qhov nruj dua li cov ntawv ntim dav dav.
Cov kev xav tau poob rau hauv ob pawg. Cov tsos mob yuav tsum tau npog qhov pom saum npoo ntawm cov ntawv ci: tsis muaj roj stains, tsis muaj sparkles, tsis muaj kab dub, tsis muaj pinholes, tsis muaj daj me ntsis thiab tsis muaj ruffles. Kev ua tau zoo yuav tsum tau npog cov kev coj tus cwj pwm, tshuaj tiv thaiv, tshuaj lom neeg ruaj khov thiab kev tu cev, vim tias cov ntawv ci tsuas yog qhov thaiv ntawm cov khoom thiab cov cua. Zoo noo noo tsis kam thiab txhim khu kev qha thaiv tiv thaiv vapor thiab roj ua kom cov khoom muaj zog ruaj khov los ntawm lub txee lub neej.
Alloy xaiv thiab Thickness Range
| Alloy | Hom tuab | Qhov chaw nyob hauv pob |
|---|---|---|
| 8011 aluminium ntawv ci | Feem ntau hauv qab 0.05 hli | Lidding thiab blister daim ntaub ntawv qhov twg nyias, formable ntawv ci yuav tsum tau |
| 8021 aluminium ntawv ci | 0.05mm thiab siab dua | Cov ntawv thov xav tau lub ntsuas hnyav dua rau lub zog, rigidity thiab sib sau qhov tob |
Yog li ntawd, ob lub alloys npog feem ntau ntawm kev ua lag luam: qib 8011 thinner thiab hnyav 8021 qib. Kev xaiv ntawm lawv yog cov lus nug ntawm kev tsim qhov tob thiab kev siv lub zog ntawm lub pob xav tau, tsis yog kev cuam tshuam kev ua haujlwm ib leeg, vim tias ob qho tib si raug xaiv rau kev ya raws, tshuaj tiv thaiv thiab kev nyiam huv hauv kev sib cuag nrog cov khoom.
Txoj Kev Ntau Lawm Kauj Ruam
Cov txheej txheem tseem ceeb ntws tau ruaj khov thiab txhua kauj ruam muaj nws lub qhov rooj zoo:
Kev tshuaj xyuas Billet - cov khoom cam khwb cia tuaj tau raug kuaj ua ntej yuav pib dov.
Billet dov - thawj theem txo qis uas tsim kom muaj tus mob metallurgical.
Split dov - lub strip yog muab ob npaug rau thiab dov ntxiv kom txo cov thickness zoo.
Coil dov - txuas ntxiv txo mus rau qhov kawg ntsuas hauv qab tswj lubrication.
Rolled tiav cov khoom - lub kauj yog tshuaj xyuas raws li cov ntawv yob.
Slitting - lub kauj yog txiav mus rau qhov dav ntawm cov kab ntim khoom xav tau.
Rauv annealing - kev kho cua sov kom muag cov ntawv ci thiab tshem tawm cov roj nplua nyeem.
Cov khoom ntim tiav lawm - cov coil annealed yog ntim rau cov khoom xa tuaj.
Kev tswj ntawm qhov chaw thiab kev ua tau zoo yog tsom rau ntawm plaub lub ntsiab lus raws txoj hauv kev no, thiab txhua tus hais txog qhov txawv ntawm qhov tsis xws luag.
Tswj Point Ib: Billet Zoo thiab Tsis Txaus Siab
Kev ua tau zoo yuav tsum tau tswj los ntawm qhov chaw. Cov khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob Pib nrog ib daim ntawv pov thawj daim ntawv pov thawj yog qhov pheej yig tshaj plaws los tiv thaiv cov tsos ntawm cov sawb.
Control Point Ob: Rolling, Slitting thiab Annealing Controls
Thaum lub sij hawm dov, qhov zoo ntawm qhov chaw yog tswj hwm los ntawm ntau qhov sib txuas sib txawv: cov rolls tau huv si thiab lawv qhov kev ntxhib los mos yog tswj, xaiv cov roj rolling uas tsim nyog, cov viscosity ntawm cov roj dov yog txo qhov xav tau, thiab kev khiav hauj lwm ceev ntawm lub tshuab yog tswj. Ua ke cov kev teeb tsa no txiav txim siab seb cov ntawv ci tawm hauv lub zeb nrog ib qho sib npaug, roj -dawb nto los yog nrog cov cim, stains thiab streaks.
Thaum lub sij hawm slitting, trimmed npoo ntawm aluminium coil yuav tsum zoo huv si thiab tsis muaj teeb meem zoo xws li ruffles, vim hais tias ib tug tsis sib luag ntug propagates rau hauv lub hlwv txoj kab thiab cuam tshuam kev noj.
Thaum lub sij hawm annealing, ob qho tib si lub sij hawm annealing thiab annealing kub yog teem raws li kev ua tau zoo ntawm cov ntawv ci. Lub hom phiaj yog dual: ncav cuag qhov xav tau softness thiab temper rau txoj kev, thiab ua kom huv si degreasing ntawm sawb. Lub voj voog annealing uas luv dhau tawm cov roj nplaum seem; ib qho uas ntev dhau los yog kub dhau tuaj yeem cuam tshuam rau cov neeg kho tshuab ntawm cov ntawv ci.
Kev tshuaj xyuas tom qab cov theem no tsom mus rau cov npe zoo li - cov roj stains, sparkles, kab dub, pinholes, daj me ntsis thiab ruffles - thiab ntawm cov khoom thaiv uas ua raws li los ntawm lawv, txij li ib tus pinhole lossis roj- cim thaj chaw cuam tshuam kev tiv thaiv cov tshuaj.
Cov lus nug nquag
Q: Dab tsi yog kws tshuaj aluminium foil siv rau?
Nws lub ntsiab siv yog blister ntim rau capsules thiab ntsiav tshuaj thiab lub hnab ntim rau hmoov granules thiab kua, qhov twg cov ntawv ci tiv thaiv cov khoom nyob rau hauv kev sib cuag nrog nws.
Q: Cov alloys twg yog siv rau cov ntawv ci tshuaj?
8011 txhuas ntawv ci thiab 8021 txhuas ntawv ci yog ob qib sib xws; 8011 feem ntau yog nyias dua 0.05 hli thiab 8021 yog 0.05 hli thiab siab dua.
Q: Dab tsi yog qhov tsis xws luag yuav tsum tsis pub dawb?
Tsis muaj roj stains, tsis muaj sparkles, tsis muaj kab dub, tsis muaj pinholes, tsis muaj daj me ntsis thiab tsis muaj ruffles, vim hais tias txhua tus ntawm lawv muaj peev xwm txo tau barrier kev ua tau zoo nyob rau hauv lub tiav pob.
Q: Yuav ua li cas yog billet zoo txuas mus rau qhov kawg nto zoo?
Kev ua tau zoo yuav tsum tau tswj los ntawm qhov chaw: billet defects xws li inclusions tsis tuaj yeem raug tshem tawm tom qab dov, yog li kev soj ntsuam nruj nruj yog thawj zaug tiv thaiv kab dub thiab pinholes.
Q: Dab tsi yog tswj thaum lub sij hawm dov theem?
Yob huv si thiab roughness, xaiv cov roj dov, txo cov roj viscosity ntawm qhov xav tau, thiab kev khiav hauj lwm ceev ntawm lub tshuab.
Q: Vim li cas lub annealing theem tseem ceeb?
Annealing lub sij hawm thiab kub yog teem kom ua tau raws li qhov yuav tsum tau ua ntawm cov ntawv ci, xa ob qho tib si temper rau kev tsim thiab huv degreasing ntawm qhov chaw.
Q: Vim li cas ntug zoo tseem ceeb tom qab slitting?
Slitting yuav tsum tawm ntawm cov npoo npoo kom huv si thiab tsis pub dawb los ntawm ruffles, vim cov ntug tsis xws luag cuam tshuam nrog kev sib sau hauv qab thiab ntim cov haujlwm.
