Tshooj 1: "Kev Lag Luam Txoj Haujlwm" ntawm n-Butane hauv Aerosol Field
1.1 Aerosol Propellant yog dab tsi?
Koj puas tau muab tshuaj tsuag plaub hau? Koj puas tau siv tshuaj tua kab? Koj puas tau siv lub tshuab cua freshener?
Lub peev xwm ntawm cov khoom lag luam no txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau sab hauv - cov pa roj lossis cov roj liquefied uas ua rau lub siab nyob hauv lub thawv kaw thiab "them" cov khoom xyaw tawm.
n-Butane yog ib qho ntawm cov khoom siv tshaj plaws hauv daim teb no.
1.2 "National Standard" rau n-Butane Propellant
Qhov tseem ceeb ntawm n-Butane hauv thaj av aerosol tuaj yeem pom los ntawm cov kev cai tshwj xeeb ntawm lub teb chaws tus qauv.
Xyoo 2008, General Administration of Quality Supervision, Inspection and Quarantine (AQSIQ) thiab Tuam Tshoj National Standardization Administration tau sib koom ua ke muab GB/T 22024-2008 "Aerosol Qib n-Butane (A-17)". Qhov no yog lub teb chaws tus qauv tshwj xeeb rau n-butane siv nyob rau hauv aerosols, cim tias n-butane raws li ib tug propellant tau nkag mus rau hauv txoj kev loj hlob theem ntawm "standardization thiab normalization".
Tshooj 2: Plaub Qhov Zoo Tshaj Plaws ntawm n-Butane ua Aerosol Propellant
2.1 Advantage 1: Stable Vapor Pressure - Tus "Controller" ntawm cov qauv tshuaj tsuag
Cov neeg siv kev paub ntawm cov khoom siv aerosol nyob ntawm qhov loj, ntawm cov qauv tshuaj tsuag - seb nws puas yog pos huab, dej loj, lossis lub dav hlau muaj zog?
Lub ntsiab parameter uas txiav txim siab tag nrho cov no yog vapor siab.
Raws li GB/T 22024-2008 tus qauv, lub vapor siab ntawm aerosol-qib n-butane muaj cov kev xav tau meej meej, thiab cov tshuab ntsuas tshwj xeeb vapor siab yog siv los txiav txim siab thaum kuaj.
Qhov kub ntawm n-Butane yog -0.5 ° C, uas txhais tau hais tias nyob rau hauv chav tsev kub, nws yog nyob rau hauv "gas-kua sib npaug" lub xeev - muaj ob qho tib si kua n-Butane thiab gaseous n-Butane nyob rau hauv lub thawv. Qhov kev sib npaug ntawm lub xeev no muab kev ruaj khov, kev xav tau siab, kom ntseeg tau tias cov nyhuv tshuaj tsuag tseem zoo ib yam los ntawm thawj cov tshuaj tsuag mus rau qhov kawg.
2.2 Qhov Zoo 2: Siab Purity thiab Tsawg Impurities - Li qub yuav tsis clog, khoom nyab xeeb
Cov "invisible killer" ntawm cov khoom aerosol yog impurities.
Yog tias n-Butane muaj cov dej noo, tsis muaj dej txaus hydrocarbons, lossis lwm yam impurities, nws yuav ua rau:
Valve clogging:Cov impurities tso rau ntawm lub valve, ua rau cov tshuaj tsuag tsis zoo los yog ua tiav qhov thaiv.
Khoom deterioration:Cov impurities teb nrog cov khoom xyaw nquag, cuam tshuam rau cov khoom zoo.
Yuav corrosion:Qee qhov impurities corrode hlau cov kaus poom, tsim kom muaj kev pheej hmoo.
GB/T 22024-2008 tus qauv muaj cov cai nruj rau kev ua kom huv ntawm aerosol-qib n-butane, kom ntseeg tau tias cov khoom ua tau raws li cov qauv kev nyab xeeb rau kev siv. Tsis tas li ntawd, tus qauv no tseem qhia txog cov kev sim, kev soj ntsuam cov cai, nrog rau cov kev cai rau kev kos npe, ntim, thauj, khaws cia, thiab kev nyab xeeb.
2.3 Qhov Zoo Tshaj Plaws 3: Kev Tiv Thaiv Ib puag ncig tus yam ntxwv - ODP=0, Tsis tshua muaj GWP
Tawm tsam keeb kwm yav dhau los ntawm kev nruj zuj zus thoob ntiaj teb kev tswj hwm ib puag ncig, qhov txiaj ntsig ib puag ncig ntawm n-Butane ua tus kiv cua yog qhov tshwj xeeb. ODP (Ozone Depletion Potential) ntawm n-Butane yog 0, txhais tau tias nws tsis ua rau cov txheej txheem ozone puas. Nws GWP (Lub Ntiaj Teb Warming Potential) kuj tseem qis dua li ntawm Freon ib txwm siv - hom propellants.
Lub ntsiab lus no tseem ceeb tshaj plaws niaj hnub no vim tias kev tswj hwm ib puag ncig tau nruj dua. Nrog rau kev nce qib ntawm Kigali Kev Hloov Kho rau Montreal raws tu qauv, lub ntiaj teb tau maj mam nce qib siab -GWP HFCs, thiab kev lag luam sib koom ntawm hydrocarbon propellants xws li n-Butane txuas ntxiv.
2.4 Qhov Zoo Tshaj Plaws 4: Tus Nqi -Kev Ua Tau Zoo - Pheej Yig, Yooj Yim Siv, Yooj Yim Kom Tau Txais
Piv nrog rau lwm cov tshuaj tiv thaiv xws li Freon thiab dimethyl ether (DME), n-Butane muaj cov txiaj ntsig zoo:
Ntau yam raw khoom:n-Butane yog los ntawm- cov khoom lag luam ntawm cov roj av tawg thiab kev ua cov pa roj, nrog cov khoom ruaj khov.
Tus nqi tsim khoom qis:Cov txheej txheem purification yog cov paub tab, nrog kev lag luam loj ntawm cov nplai.
Yooj yim ntim thiab thauj:Lub ntim me me thaum liquefied, yooj yim rau khaws thiab thauj.
Rau cov lag luam aerosol ntau lawm, xaiv n-Butane ua ib lub tshuab hluav taws xob txhais tau tias cov khoom siv qis dua thiab cov saw hlau ruaj khov dua.
Tshooj 3: Daim Ntawv Thov Kev Sib Tham ntawm Aerosol-Qib n-Butane
3.1 Cov Khoom Siv Kho Tus Kheej - Cov Tshuaj Txhuam Hniav, Mousses, Tshuaj Txhuam Hniav
Nov yog daim ntawv thov ntau tshaj plaws rau n-Butane propellant.
Cov khoom xws li tshuaj tsuag plaub hau, mousses, thiab tshuaj pleev thaiv hnub yuav tsum tau muab cov khoom xyaw sib npaug rau ntawm daim tawv nqaij lossis plaub hau. Lub siab ruaj khov muab los ntawm n-Butane ua kom qhov zoo thiab qhov sib xws ntawm cov tshuaj tsuag, muab kev paub zoo rau cov neeg siv.
3.2 Cov Khoom Siv Hauv Tsev - Cov tshuaj tua kab, Cov Cua Txias Txias, Cov tshuaj ntxuav
Cov tshuaj tua kab yuav tsum tau txau cov tshuaj ua kua rau hauv txhua lub ces kaum ntawm chav tsev, huab cua fresheners yuav tsum tau sib npaug ntawm cov tshuaj tsw qab, thiab cov tshuaj ntxuav tes yuav tsum tau npog cov stains nrog npuas - tag nrho cov xwm txheej no xav kom tus kiv cua los muab cov tshuaj tsuag txaus thiab cov qauv tshuaj tsuag ruaj khov.
3.3 Cov khoom lag luam - Cov tshuaj tiv thaiv xeb, Lubricants, Pwm tso tus neeg sawv cev
Hauv kev lag luam, n-Butane propellant kuj tau siv dav:
Cov tshuaj tiv thaiv kab mob xeb:Tiv thaiv hlau nto.
Lubricant sprays:Lubricate mechanical qhov chaw.
Pwm tso tus neeg sawv cev txau:Tso cov pwm hauv pwm tsim.
3.4 Automotive Care Products - Cov tshuaj ntxuav tu, Tus neeg saib xyuas tu
Hauv thaj chaw saib xyuas tsheb, n-Butane propellant yog siv rau hauv cov tshuaj ntxuav thiab tu cov neeg ua haujlwm, xav tau kev ruaj ntseg ntawm qhov kub thiab txias.
