Dab tsi txhais cov khoom siv lub raj mis
Lub raj mis cap yog nyias, tsim kaw. Nws txoj haujlwm yog kaw lub thawv, tuav lub siab sab hauv lossis lub tshuab nqus tsev, thiab muaj sia nyob puv, pasteurisation, thauj thiab khaws cia ntev yam tsis muaj dej. Vim hais tias ib feem yog tsim los ntawm blanking, sib sib zog nqus nqus thiab curling es tsis yog los ntawm machining, cov tswv yim yuav luag ib txwm wrought txhuas ntawv, coil los yog ntawv ci es tsis yog cam khwb cia khoom. Nyob rau hauv kev xyaum, kaw kev lag luam ua hauj lwm nyob rau hauv lub 0.14 hli mus rau 0.30 hli gauge band nyob ntawm seb hom cap.
Plaub tsev neeg hlau muab cov qhab nia: 1xxx (kev lag luam ntshiab), 3xxx (aluminium-}manganese), 5xxx (aluminium-}magnesium) thiab 8xxx (aluminium- hlau-silicon) series. Txhua tus yog xa mus rau hauv lub siab txhais raws li EN 515 / ANSI H35.1 temper system, feem ntau H14 (quarter nyuaj), H16 (ib nrab nyuaj) lossis H18 (tag nrho nyuaj). Qhov kev xaiv yog tsav los ntawm plaub lub zog: formability nyob rau hauv qhov sib sib zog nqus- kos duab kev taw qhia, lub zog tom qab ua hauj lwm hardening, corrosion kuj tiv thaiv cov khoom, thiab nto zoo rau lacquering los yog luam ntawv.
Kev sib xyaw ntawm Main Kaw Alloys
Cov lus hauv qab no teev cov kev txwv tsis pub tshaj tawm hauv GB / T 3190 thiab EN 573-3. Tsuas yog ntau yam uas tau tswj hwm los ntawm tus qauv yog qhia; cov ntsiab lus uas tsis tau teev npe muaj nyob hauv cov qib residual.

Yuav ua li cas Txhua Series coj tus cwj pwm hauv kev tsim khoom
1xxx series
Kev lag luam ntshiab aluminium yog qhov kev xaiv softest. Nws muaj qhov siab tshaj plaws elongation thiab lub zog qis tshaj ntawm plaub tsev neeg, yog li nws blanks thiab kos tau yooj yim thiab siv daim iav polish los yog ci anodised tiav. Nws qhov kev txwv yog txhua yam: lub hau tsim los ntawm 1050 lossis 1060 nyob rau hauv cov mob annealed deforms nyob rau hauv lub teeb ntiv tes siab, yog li cov alloys siv qhov chaw kaw yog cov hniav zoo nkauj, los yog qhov twg ib tug nyias tamper band nqa lub load.
3xxx series
Manganese nce lub zog yam tsis muaj kev rhuav tshem cov ductility thiab muab cov hlau ua kom muaj txiaj ntsig zoo rau atmospheric corrosion, uas yog vim li cas 3003 tau los ua cov khoom siv hauv cov dej haus classic. 3104 ntxiv magnesium rau ntxiv dag zog thiab siv qhov chaw kaw yuav tsum tiv taus siab dua sab hauv. Sib sib zog nqus kev ua tau zoo tseem zoo vim tias manganese khaws cov txheej txheem recrystallised zoo.
5xxx series
Magnesium yog qhov tseem ceeb ntxiv hauv 5052 thiab lwm yam alloys. Cov ntaub ntawv no ua ke nrog lub zog nruab nrab nrog kev elongation zoo thiab ua haujlwm zoo rau cov dej ntsev thiab ntau cov zaub mov acids. Hauv kev kaw lawv feem ntau tshwm sim hauv tamper- cov nplhaib thiab cov hlua ruaj ntseg, qhov chaw yuav tsum nyob nrog thaum raug khoov los ntawm lub kaum sab xis loj thaum qhib.
8xxx series
8011 yog ib qho txhuas- hlau- silicon alloy tsim rau ntawv ci thiab lub teeb - ntsuas ntawv. Nws qhov sib xyaw ua ke ntawm cov pob ntseg qis thiab cov cim nce hauv lub zog tom qab txo qhov txias ua rau nws xaiv tus qauv rau pilfer- pov thawj lub kaus mom thiab yob- ntawm pilfer- pov thawj (ROPP) cawv kaw. Nws yog ib txwm muab rau hauv H14, H16 lossis H18 nyob ntawm seb qhov yuav tsum tau ua kom nruj.
Daim ntawv thov Scenario
Npias thiab carbonated dej qab zib:yas kaus mom tsim los ntawm 3003 lossis 3104 daim ntawv, lacquered sab hauv los tiv thaiv kev cuam tshuam nrog dej haus.
Caw thiab ntsuj plig:ROPP aluminium plhaub nyob rau hauv 8011, feem ntau yog dai kom zoo nkauj thiab lined nrog barrier wad.
Pharmaceutical vials:pilfer- pov thawj txhuas lub kaus mom thiab cov ntsaws ruaj ruaj los ntawm 8011 H18, feem ntau ua ke nrog cov roj hmab septum.
Tshuaj pleev ib ce thiab saib xyuas tus kheej:anodised los yog luam tawm plhaub los ntawm 1050 thiab 1060 qhov twg zoo li dominates.
Khoom noj jars:twist -tawm qhov kaw xav tau lub lacquer ruaj khov thiab tswj tau qhib lub zog.
Xaiv thiab sau ntawv
Ua kom npau taws los kos qhov tob. Lub plhaub sib sib zog nqus hauv lub siab tawv yuav tsim kua muag ntawm lub khob phab ntsa; mus rau ib tug temper softer es tsis ntxiv lubricant.
Tswj pob ntseg. Planished, qis-earing 8011 khaws cov trimmed cap rim theem thiab txo cov seem.
Teem cov cuab yeej tshem tawm rau qhov ntsuas tau xa tawm tiag tiag, tsis yog lub ntsuas ntsuas nominal, thiab txheeb xyuas qhov tuab tuab ntawm cov npoo npoo.
Npaj lub nto rau lacquer: degrease thiab, qhov twg yuav tsum tau, siv ib tug conversion txheej. Txheej adhesion, tsis yog txheej tuab ib leeg, txiav txim siab seb lub hau puas muaj sia nyob pasteurisation.
Xyuas cov wad los yog liner cov ntaub ntawv tiv thaiv cov khoom ntim. Lub alloy tsis tshua muaj ua ntej lub hauv ob sab phlu.
Common Misconceptions
softer ib txwm txhais tau tias zoo dua.Softness pab kev kos duab tab sis txo qis qhov ntsuas siab ntawm lub hau tiav.
Tag nrho 8011 ntawv ci yog sib hloov.Kev sib xyaw ua ke yog tus qauv, tab sis kev npau taws, ntsuas qhov siab ntev thiab kev coj cwj pwm tsis zoo, thiab lawv txiav txim siab ua haujlwm.
Lub thicker cap seals zoo dua.Sealing yog ib txoj haujlwm ntawm liner compression thiab cap geometry; ntxiv gauge mas nce nqi thiab tooling load.
Siab purity guarantees corrosion kuj.Kev ua haujlwm yog nyob ntawm cov khoom ntim khoom thiab ntawm lacquer zoo npaum li ntawm txhuas purity.
FAQ
Q: Qhov twg aluminium alloy feem ntau yog rau pilfer-cov ntaub ntawv pov thawj?
8011, feem ntau nyob rau hauv H14 lossis H18 temper, vim hais tias nws sib txuas cov pob ntseg qis nrog lub zog zoo tom qab ua haujlwm txias.
Q: 1050 puas tuaj yeem siv rau carbonated dej haus yas?
Nws tsim tau yooj yim tab sis nws lub zog qis ua rau nws xaiv tsis zoo rau kev tuav cia; 3003 lossis 3104 yog nyiam.
Q: Dab tsi gauge siv rau lub raj mis daim ntawv thiab ntawv ci?
Kev kaw feem ntau yog tsim los ntawm 0.14 hli mus rau 0.30 hli cov khoom siv, nrog rau qhov ntsuas qhov tseeb ntawm lub taub hau, kos qhov tob thiab qhov xav tau qhib lub zog.
Q: Vim li cas 5052 tshwm sim hauv kev kaw?
Nws cov ntsiab lus magnesium muab lub zog ntau dua thiab ua haujlwm zoo dua rau cov khoom siv ntsev thiab kua qaub, uas haum rau tamper - cov nplhaib uas yuav tsum khoov yam tsis muaj qhov tawg.
Q: Puas yog temper cuam tshuam rau lacquer adhesion?
Nws cuam tshuam qhov kev ntxhib los mos ntawm qhov chaw tsim los ntawm dov. Nyuaj tempers feem ntau nthuav tawm qhov smoother nto, tab sis adhesion tseem nyob ntawm degreasing thiab hloov dua siab tshiab txheej ua ntej lacquering.
Q: Puas yog txhuas ntawv ci rau lub hau npog los ntawm EN 541?
EN 541 npog aluminium ntawv ci rau ntim, uas suav nrog cov ntsuas txog li 0.20 hli; Cov khoom hnyav kaw feem ntau yog txiav txim siab rau daim ntawv thiab strip specifications xws li EN 485-2 lossis ASTM B209.
