Cyclopentane thiab isopentane tuaj yeem sib xyaw ua ke. Sib tov ob qho tib si hauv ib qho piv txwv yog kev paub daws teeb meem hauv kev ua kom lub tub yees foaming.
Cyclopentane (C₅H₁₀, boiling point 49.3 degree) thiab isopentane (C₅H₁₂, boiling point 27.7 degree) yog sib tov kom ua tiav cov txiaj ntsig zoo thiab cov nqi optimization. Cov txheej txheem loj tshaj plaws yog cyclopentane / isopentane (70/30) sib xyaw ua ke. Piv nrog rau cov ntshiab cyclopentane, nws tuaj yeem ua tiav qhov txo qis ntawm cov nqi them ntawm kwv yees li 7% thiab txo cov npuas ntom ntom ntawm 10-12%, thaum tuav lub cev tsis hloov pauv. Mixed foaming technology tau siv rau hauv kev lag luam tub yees rau ntau tshaj nees nkaum xyoo, thiab cov tuam txhab ua lag luam xws li Haier thiab Midea tau txais kev daws teeb meem no. Txawm li cas los xij, nws yuav tsum tau muab sau tseg tias ob qho tib si cyclopentane thiab isopentane yog Class A flammable kua (flash ntsiab lus ntawm -37℃thiab -51℃feem). Kev sib xyaw thiab siv yuav tsum tau ua nyob rau hauv kev cob qhia uas tau dhau los ua pov thawj tawg thiab tiv thaiv zoo li qub retrofitting. Nanjing ZL Energy Co., Ltd. tshwj xeeb hauv kev tshawb fawb thiab kev tsim cov tshuaj hydrocarbon tshuab, muab kev pabcuam sib xyaw pentane rau ntau qhov sib piv xws li 70/30, pab cov lag luam ua tiav ob qho kev tiv thaiv ib puag ncig thiab cov txiaj ntsig zoo.
Tshooj 1: Teb ncaj nraim - Lawv tuaj yeem sib xyaw ua ke, Thiab Nws yog Kev Lag Luam Loj Loj
Cyclopentane thiab isopentane tsis tuaj yeem tsuas yog sib xyaw, tab sis sib xyaw ob hauv ib qho piv txwv tau dhau los ua kev paub daws teeb meem hauv thaj chaw ntawm polyurethane foaming rau cov tub yees thiab lub tub yees.
Raws li thaum ntxov xyoo 2002, cyclopentane / isopentane blended foaming technology tau siv rau cov kab ntau lawm ntawm cov tub yees tseem ceeb xws li Haier. Tam sim no, cov cuab yeej zoo sib cais rau cov khoom sib xyaw pentane isomers kuj tau ua lag luam, ua rau kev tsim cov khoom sib xyaw tshuab hauv ntau qhov sib piv.
Zhonglian Zog cov khoom catalog kom meej meej sau cov khoom sib xyaw isopentane/cyclopentane (30/70). Cov ntaub ntawv tseem ceeb kuj lees paub tias cov txheej txheem tsim khoom siv rau cyclopentane thiab cyclopentane / isopentane foaming systems yog qhov tseem ceeb tib yam.
Tshooj 2: Vim li cas thiaj sib xyaw lawv? - Ua kom muaj txiaj ntsig zoo, txo nqi, thiab txhim kho kev ua tau zoo
Lub logic tom qab sib xyaw lawv yog txhawm rau txhim kho cov txheej txheem foaming los ntawm kev siv qhov sib txawv ntawm cov ntsiab lus boiling - cyclopentane muaj qhov kub kub kub, muab cov pob txha txhawb nqa thiab qhov ruaj khov, thaum isopentane muaj qhov kub siab qis, lub luag haujlwm rau kev txhim kho fluidity thiab cell sab hauv siab.
2.1 30% Isopentane Ntxiv: Kev Lag Luam- Pom "Golden Ratio"
Cov ntaub ntawv kev kawm los ntawm ZL Zog qhia tau hais tias cyclopentane rau isopentane qhov hnyav piv ntawm 7: 3 (ie, 70/30) yog cov qauv siv dav tshaj plaws hauv kev lag luam.
| Sib piv Indicator | Ntshiab Cyclopentane | Cyclopentane / Isopentane (70/30) | Hloov Range |
|---|---|---|---|
| Cell sab hauv siab | 0.45bar ib | 0.55bar ib | ↑ 22% |
| Tus nqi them | Lub hauv paus | Txo los ntawm kwv yees li 7% | ↓ 7% |
| Ua Npuas Ncauj | Lub hauv paus | Txo los ntawm 10-12% | ↓ 10-12% |
| Lub cev muaj zog | Lub hauv paus | Tseem tsis hloov | Sib npaug |
Cyclopentane / isopentane blended foaming thev naus laus zis tuaj yeem txo tus nqi ntawm polyurethane raw khoom siv los ntawm kwv yees li 8% thaum tswj cov txheej txheem tib yam thiab ua npuas ncauj lub cev.
2.2 Lub hauv paus ntsiab lus ntawm Cov nyhuv: Isopentane Ntxiv Ua Li Cas Txhim Kho Ua npuas ncauj?
Ua ntej, nce cell sab hauv siab.Lub siab sab hauv ntawm cov ntshiab cyclopentane- tshuab ua npuas ncauj yog kwv yees li 0.45 bar, thaum lub cyclopentane / isopentane (70/30) sib xyaw ua ke tuaj yeem nce mus rau 0.55 bar. Qhov siab dua ntawm tes hauv siab txo cov kev cuam tshuam ntawm sab nraud quab yuam ntawm cov npuas dej, piv txwv li, txo qis qhov sib txawv ntawm sab hauv thiab sab nraud ntawm lub hlwb, yog li txhim kho qhov ruaj khov.
Thib ob, txhim kho fluidity thiab filling peev.Isopentane muaj qhov kub ntawm tsuas yog 28℃thiab tuaj yeem vaporize nyob rau theem pib ntawm cov tshuaj tiv thaiv polyurethane, thaum sib xyaw ntawm polyol thiab isocyanate tseem yog cov kua viscosity tsawg. Tus neeg sawv cev tshuab ua haujlwm ua ntej thiab ntau yam sib xws, txhim kho qhov muaj peev xwm txaus (sau muaj peev xwm) ntawm polyurethane system.
Thib peb, txo cov nqi tsim khoom.Thaum siv cyclopentane / isopentane foaming tshuab thiab ua kom lub zog compressive siab tshaj tus nqi teev, lub txee nqi (lossis qhov ceev) raug txo los ntawm kwv yees li 10% piv rau cyclopentane foaming system. Qhov no txhais tau tias cov khoom siv tsawg dua tuaj yeem siv rau tib yam khoom.
Tshooj 3: Qhov txawv ntawm Cov nyhuv - Cyclopentane/Isopentane vs. n-Pentane/Isopentane
Muaj qhov sib txawv tseem ceeb ntawm cov txiaj ntsig ntawm cyclopentane / isopentane mix system thiab n-pentane / isopentane mix system - yav dhau los muaj kev ua haujlwm zoo thermal rwb thaiv tsev, thaum tom kawg muaj tus nqi qis dua tab sis siv zog dua.
Raws li cov ntaub ntawv sib piv los ntawm kev lag luam technical data:
| Mixed System | Qhov zoo | Qhov tsis zoo |
|---|---|---|
| Cyclopentane / Isopentane | Kev ua haujlwm zoo thermal rwb thaiv tsev, txee lub zog ua tau raws li cov qauv | Tus nqi siab dua |
| n-Pentane/Isopentane | Advantage nyob rau hauv qhov ceev (sau tus nqi) txo | Txee lub zog noj yog siab dua qhov siv tshuab cyclopentane |
Lub n-pentane/isopentane tov foaming tshuab tau sim los ntawm qee lub tuam txhab kwv yees li rau lub hlis tom qab kev qhia txog cyclopentane. Txawm li cas los xij, cov thev naus laus zis no tau ua rau lub zog siv hluav taws xob ntau dua li cov tshuab cyclopentane. Yog li ntawd, hauv cov khoom siv hauv tsev uas qhov kev ntsuas kev siv hluav taws xob tau ua raws, cyclopentane / isopentane mix system tseem yog qhov kev xaiv tseem ceeb.
Tshooj 4: Cov teeb meem kev nyab xeeb uas yuav tsum tau soj ntsuam thaum sib tov
Ob qho tib si cyclopentane thiab isopentane yog Class A flammable kua. Kev sib xyaw thiab kev siv yuav tsum tau ua nyob rau hauv kev cob qhia uas tau tawg lawm - pov thawj thiab tiv thaiv - zoo li qub retrofitting.
4.1 Hazard Classification of Pentanes
Raws li tsab ntawv ceeb toom kev pheej hmoo tshaj tawm los ntawm Guizhou Provincial Department of Ecology thiab Ib puag ncig xyoo 2020:
| Khoom npe | Flash Point | Hluav Taws Kub Hazard Class |
|---|---|---|
| Cyclopentane | -37 degree | A |
| Isopentane | -51 degree | A |
| n-Pentane | -48 degree | A |
| Cyclopentane Polyol Blend | Kaw khob flash point<28°C | A |
Pure pentane-raws li cov khoom lag luam yog tag nrho cov khoom phom sij hauv Class A. Pentane muaj kev sib raug zoo nrog polyether tsis zoo thiab nws yooj yim rau kev khiav tawm, yog li ua ntej - sib xyaw pentane polyol blends tseem muaj qhov txaus ntshai heev.
4.2 Kev tawg-Cov ntaub ntawv pov thawj uas yuav tsum tau ntsib thaum siv
Cov tuam txhab lag luam uas tsis tau tawg lawm- pov thawj thiab tiv thaiv - zoo li qub retrofitting thiab koom nrog kev tsim khoom thiab kev siv ua ntej - cov khoom sib xyaw pentane polyol yog ua txhaum lub teb chaws txoj cai ntawm kev siv cov khoom phom sij, ua rau muaj kev phom sij loj heev.
Cov xwm txheej tsim nyog suav nrog:
| Qeb | Kev xav tau |
|---|---|
| Cov khoom siv hluav taws xob | Tag nrho cov teeb pom kev zoo, qhov cua, thiab lub cev muaj zog yuav tsum tawg - pov thawj |
| Kev tiv thaiv zoo li qub | Cov thawv ntim khoom thiab cov khoom tau txais yuav tsum yog hauv av thiab sib koom ua ke |
| Cov txheej txheem ua haujlwm | Yuav tsum tsis txhob hnav khau nrog cov ntsia hlau hlau lossis cov khaub ncaws ua haujlwm hluavtaws; yuav tsum tso tawm hluav taws xob zoo li qub los ntawm kev tuav lub hauv paus railing ua ntej ua haujlwm |
| Cia ib puag ncig | Warehouse kub yuav tsum tsis txhob siab tshaj 29 degree; khaws cia cais los ntawm oxidizers |
| Qhov yuav tsum tau muaj cua tshuab | Mechanical qhov cua yuav tsum tau ntsia kom tiv thaiv vapor tsub zuj zuj |
