Aluminium ointment tubes yog cov tsim thawj pob rau cov tshuaj pleev ib ce vim hais tias lub cev hlau muab ib qho kev cuam tshuam rau lub teeb, oxygen, dej vapor thiab micro{0}} kab mob. Kev ua tau zoo yog nyob ntawm alloy purity, phab ntsa thickness, lacquer system thiab qhov seem tswj ntawm lub nozzle thiab kaw.
Tube Kev tsim kho thiab kev xaiv Alloy
Lub raj collapsible muaj ib lub cev hlau mos, ib lub xub pwg thiab lub nozzle, lub hauv paus kaw thiab kaw. Lub cev yog rub los yog cuam tshuam extruded los ntawm qis alloy, siab purity aluminium: 1050, 1060, 1070 thiab 1235 yog tus qauv, feem ntau ntawm 99.5 feem pua purity lossis siab dua, vim hais tias cov ntsiab lus cuam tshuam rau ob qho tib si formability thiab kev cuam tshuam nrog cov formulation. Phab ntsa thickness feem ntau yog 0.09 txog 0.15 hli, nrog 0.10 mus rau 0.13 hli qhov ntau lawm ntau yam; thinner phab ntsa txo qhov hnyav tab sis ua rau lub raj muaj dents hauv kev faib khoom. Tube diameters ib txwm khiav ntawm li 11 hli mus rau 40 hli, npog ntim ntim los ntawm kwv yees li 5 g mus rau 200 g. Rau ib zaug -siv los yog cov khoom viscous lub nozzle raug kaw los ntawm ib qho membrane uas lub hau pierces ua ntej siv. Cov ntawv ci rau lub raj xa khoom raug txiav txim rau GB / T 3198 lossis EN 546 series, uas cais cov txheej txheem kev ua haujlwm, cov khoom siv kho tshuab thiab qhov ntev ntev, kom tawv thiab tuab yog kev cog lus.
Barrier Performance thiab Internal Lacquer Systems
Lub cev hlau yog ib qho kev txwv tsis pub, yog li qhov kev pheej hmoo ntawm kev sib raug zoo tsuas yog los ntawm kev sib cuag ncaj qha ntawm txhuas thiab cov qauv tsim. Cov khoom siv acidic lossis fatty, thiab cov uas muaj chloride ions lossis sulfur compounds, tuaj yeem hnov mob nrog aluminium liab qab. Cov txheej txheem kev daws teeb meem yog cov lacquer sab hauv, feem ntau yog epoxy-phenolic lossis polyester system thov ntawm 6 txog 12 micron qhuav zaj duab xis hnyav, uas tseem tiv thaiv cov hlau los ntawm kev tsim-induced corrosion. Kev xaiv lacquer yog nyob ntawm pH thiab hnyav cov ntsiab lus ntawm kev sau, thiab kev txuas ntxiv raug txheeb xyuas hluav taws xob ntawm cov kab ntau lawm. Cov ntaub ntawv txheej thiab cov khoom tiav yuav tsum ua kom tiav raws li kev cai tswjfwm: EU 1935/2004 rau cov khoom sib cuag zaub mov teeb tsa tag nrho kev tsiv teb tsaws ntawm 10 mg / dm2 lossis 60 mg / kg, 21 CFR 175.300 npog resinous thiab polymeric coatings ntawm cov hlau hauv Tebchaws Meskas, thiab cov ntaub ntawv yas yog kaw los ntawm EU los yog cov ntaub ntawv yas. 10/2011. Adhesion ntawm lacquer tom qab tsim thiab tom qab sau yog kuaj los ntawm daim kab xev xeem txoj kev xws li ASTM D3359, thiab dej vapor kis ntawm laminate los yog liner cov ntaub ntawv yog ntsuas rau ASTM E96.
Dimensional Tolerances thiab Kaw Systems
Dimensional tswj txiav txim seb lub raj puas khiav ntawm ib txoj kab tsis siv neeg puv. Qhov ntev tseem ceeb yog lub taub hau thiab xov daim ntawv, lub xub pwg txoj kab uas hla, lub cev txoj kab uas hla thiab tag nrho ntev. Phab ntsa thickness variation, roundness thiab camber yog hais rau cov chav kawm kam rau ua los ntawm EN 546-3 los yog tus qauv sib npaug. Kaw yog feem ntau polypropylene los yog siab ceev polyethylene lub kaus mom, nrog ib tug liner los yog ib tug plug seal xaiv rau cov formulation; tamper pov thawj yog muab los ntawm ib tug nco nplhaib los yog ib tug kaw band. Nozzle membrane thickness thiab puncture quab yuam yuav tsum tau teev ua ke, vim hais tias ib daim nyias nyias uas tuab heev yog nyuaj rau tus neeg mob mus tho thiab ib tug nyias nyias yuav tsis ua hauj lwm. Tube-rau-cap torque, kev sim poob thiab kev ntsuas siab sab hauv yog qhov kev tso tawm niaj hnub.
Kev tswj hwm thiab kev huv huv
Cov khoom ntim tseem ceeb rau cov khoom siv tshuaj yog tsim nyob rau hauv kev tswj hwm zoo rau cov khoom ntim, thiab cov kev taw qhia siv tau yog ISO 15378, uas siv cov qauv kev tsim khoom zoo rau luam tawm thiab tsis luam tawm thawj lub ntim. Kev ntsuas kev ua tau zoo ntawm cov thawv ntim tshuaj ua raws li cov txheej txheem tshuaj xws li USP 671, thiab hauv Suav teb cov ntaub ntawv ntim tshuaj tau tswj hwm los ntawm YBB series ntawm lub teb chaws ntim khoom cov qauv. Cov tswv yim ntxuav chav tswj npog npog cov huab cua hauv cov khoom suav, cov roj nplaum seem thiab kos cov xab npum rau ntawm qhov chaw sab hauv, thiab cov ntawv ci khib nyiab. Cov chaw tsim khoom rau lub cev raj thiab lacquering feem ntau ua haujlwm ntawm ISO 8 chav huv huv, nrog kev tswj nruj dua ntawm lub nozzle thiab sab hauv lub hau. Batch ntaub ntawv ib txwm muaj xws li daim ntawv pov thawj alloy, lacquer batch, migration test data thiab dimensional records.
Cov lus nug nquag
Q:Dab tsi purity puas aluminium ointment tube Tshuag xav tau?
A: Alloys xws li 1050, 1060, 1070 thiab 1235 yog siv ntawm 99.5 feem pua purity los yog siab dua, yog li cov kab lus tsis cuam tshuam rau formability lossis formulation compatibility.
Q:Vim li cas txhuas raj xav tau ib lub lacquer sab hauv?
A: Acidic, fatty los yog chloride-muaj cov formulations tuaj yeem hnov qab nrog aluminium liab qab. A 6 txog 12 micron epoxy-phenolic lossis polyester lacquer cais cov hlau thiab tiv thaiv cov khoom thiab cov raj.
Q:Dab tsi ntawm phab ntsa thickness yog raug rau cov tshuaj pleev xim raj?
A: Ntawm 0.09 txog 0.15 hli, feem ntau 0.10 txog 0.13 hli. Cov phab ntsa thinner txo qhov hnyav tab sis ua rau muaj kev pheej hmoo ntawm denting thaum muab faib.
Q:Cov kev cai twg siv rau lub raj lacquer thiab kaw?
A: EU 1935/2004 nrog rau tag nrho kev tsiv teb tsaws txwv ntawm 10 mg / dm2 lossis 60 mg / kg, 21 CFR 175.300 rau cov txheej txheem ntawm cov hlau hauv Tebchaws Meskas, thiab EU 10/2011 rau cov kaus mom yas thiab cov hnab yas.
Q:Yuav ua li cas lacquer continuity soj ntsuam nyob rau hauv ntau lawm?
A: Hluav taws xob, siv cov khoom siv hluav taws xob raws li enamel- ntsuas ntsuas ntawm lub raj tiav, txhawb nqa los ntawm kev kuaj adhesion rau ASTM D3359 tom qab tsim.
Q:Puas yog aluminium raj xav tau kom tsis muaj menyuam?
A: Cov khoom siv tshuaj pleev ib ce feem ntau tsis yog -sterile, yog li kev txwv microbial ntau dua li siv tsis tau. Qhov twg yuav tsum tau ua kom tsis muaj menyuam, lub raj thiab lub kaw lus kaw yuav tsum raug lees paub rau txoj kev xaiv kom tsis muaj menyuam thiab cov lacquer re- tsim nyog tom qab ntawd.
