Peb cov neeg ua haujlwm hauv polyurethane foaming lossis refrigerant procurement yeej tau ntsib qhov xwm txheej surreal thaum tshawb nrhiav n-butane cov neeg muag khoom hauv online: ntau pua tus neeg muag khoom tshwm sim hauv cov txiaj ntsig tshawb nrhiav, txhua tus tau lees tias yog thawj qhov chaw, tab sis thaum kuaj cov qauv, noo noo tshaj cov qauv, cov ntxhiab tsw yog pungent, thiab thaum ntxiv rau polyols ua npuas ncauj, ua npuas ncauj. Dab tsi yog cov neeg muab khoom ntawm n-butane? Koj tuaj yeem yuav cov khoom siv txhim khu kev qha uas tsis xav tau kev soj ntsuam tas li ntawm cov ntaub ntawv soj ntsuam zoo? Niaj hnub no, peb yuav nthuav tawm qhov tseeb ntawm kev lag luam no thiab piav qhia qhov tseem ceeb ntawm kev yuav khoom.
n-Butane cov neeg muag khoom nyob rau hauv kev ua lag luam feem ntau muab faib ua peb pawg: refinery los ntawm - hom khoom, C4 nplua cais hom, thiab cov tub luam roj. Xaiv qhov tsis ncaj ncees lawm ncaj qha txiav txim siab batch stability ntawm koj cov ntaub ntawv raw.
Thaum nrhiav tus neeg muag khoom, ua ntej xyuas seb lawv cov khoom los ntawm qhov twg. n-Butane feem ntau yog los ntawm cov roj av refineries thiab ethylene cracking units. Cov neeg muab khoom los ntawm ntau qhov chaw muaj qhov sib txawv loj heev. Tsis txhob cia li saib tus nqi tsev dig muag.
| Yam khoom | Qhov Chaw Muab Khoom | Hom Purity Limit | Core Advantages thiab Disadvantages Analysis | Pab pawg yuav khoom tsim nyog |
|---|---|---|---|---|
| Refinery Los ntawm -Cov khoom lag luam | Lub teeb hydrocarbon los ntawm -cov khoom los ntawm catalytic cracking lossis atmospheric/vacuum distillation | Feem ntau Tsawg dua lossis sib npaug li 95% | Qhov zoo: ntim loj, tsis tshua muaj nqi. Disadvantages: Muaj ntau ntau ntawm isobutane, pentane, thiab olefins, nrog cov khoom sib txawv heev thiab tsis muaj kev tswj xyuas zoo. | Tsawg- roj kawg, combustion crude tsis muaj purity yuav tsum tau. |
| Fine Separation Type (Qhov Chaw Tsim Khoom) | Precision distillation extraction los ntawm C4 feem | Yuav ncav cuag Ntau dua lossis sib npaug li 99.5% | Qhov zoo: Tsis tshua muaj impurities, tswj tau noo noo thiab sulfur cov ntsiab lus, cov khoom ruaj khov heev. Disadvantages: Yuav tsum tau dais nqi purification, me ntsis siab dua chav tsev nqi. | Polyurethane foaming, tub yees, siab -purity standard gases. |
| Gas Traders | Kev xa khoom thiab rov ntim khoom los ntawm ntau qhov chaw cog ntoo | Mixed (90% -99%) | Qhov zoo: Cov lus teb ceev ceev, yooj yim mus yuav hauv lub tog raj kheej me me. Disadvantages: Cov khoom tsis ruaj khov, kev pheej hmoo ntawm kev kis kab mob thib ob thaum lub sij hawm txhaws, tus nqi suav nrog tus neeg nruab nrab markup. | Laboratories nrog me me ntim los yog ib ntus ntxiv. |
Yog tias koj daim ntawv thov yog tus neeg sawv cev tshuab lossis cov tub yees, yuav cov khoom siv roj av los ntawm lub tshuab ua kom zoo yog nug txog teeb meem. Kev yuav los ntawm cov tub luam txhais tau tias muaj kev pheej hmoo ntawm kev hloov pauv. Tsuas yog zoo sib cais hom qhov chaw manufacturers yog txoj kev.
Qhov kev ntseeg siab tshaj plaws rau kev yuav khoom n-Butane yog kos npe rau ib lub sijhawm ntev - daim ntawv cog lus muab khoom ncaj qha nrog lub Hoobkas uas muaj peev xwm sib cais zoo, tsis yog nrhiav cov khoom siv los ntawm ntau qhov chaw.
Tam sim no peb nkag siab txog kev faib cov khoom lag luam, cov lus nug tom ntej yog qhov twg yuav yuav. Cov tshuaj phem ntau tsis yooj yim li kev xaj ntawm Taobao. Raws li txoj cai thiab ruaj khov feem ntau koom nrog cov npe thiab sib piv los ntawm cov chaw lag luam tshuaj lom neeg xws li Dalian Cov Khoom Muag Khoom Muag, lossis kos npe ncaj qha txhua xyoo / peb lub hlis twg ntev - cov lus cog lus ncaj qha nrog cov chaw tsim khoom.
Lub khw muag khoom tob heev. Ntau tus tub luam coj cov khoom los ntawm ib lub Hoobkas hnub no thiab lwm tag kis, thiab sib tw ntawm tus nqi, lawv txawm sib tov hauv siab -olefin crude butane. Yog tias koj yog tus neeg siv sijhawm ntev - daim ntawv cog lus, nws raug pom zoo kom hla cov neeg nruab nrab thiab txuas ncaj qha nrog cov kab ntau lawm. Thaum yuav khoom, tsis txhob nug "ntau npaum li cas ib tuj ntawm n-butane"; koj yuav tsum hais koj daim ntawv thov:
Foaming Qib n-Butane:Yuav tsum tau purity Ntau dua los yog sib npaug rau 99%, nrog rau cov tseem ceeb tswj ntawm noo noo (tsawg dua los yog sib npaug rau 30 ppm) thiab olefin cov ntsiab lus. Txwv tsis pub, polyurethane blends tuaj yeem ua tsis tau yooj yim.
Refrigerant Qib n-Butane:Yuav tsum tau purity Ntau dua los yog sib npaug li 99.5%, xa mus rau "Txoj Kev Cai Sau Cov Tub Txias thiab Kev Nyab Xeeb Kev Nyab Xeeb" (GB / T 7778), nrog rau cov ntsiab lus nruj heev ntawm sulfur los tiv thaiv compressor tooj liab plating.
Qhov kev pheej hmoo loj tshaj plaws hauv kev yuav khoom n-Butane tsis yog tus nqi hloov pauv, tab sis catalyst lom thiab cov khoom siv corrosion tshwm sim los ntawm cov kab tsis zoo (dej, sulfur, olefins).
Ntau tus kws tshaj lij kev muag khoom, thaum sib piv cov nqi, tsuas yog saib ntawm 99% tus lej purity thaum tsis quav ntsej "cov khoom tsis huv" tom qab nws. Qhov no yog qhov tob tshaj plaws hauv kev lag luam. Raws li cov qauv xws li "Industrial n-Butane" (SH/T 0553), noo noo thiab sulfur cov ntsiab lus yog qhov taw qhia nyuaj.
Crude n-butane feem ntau muaj cov lej ntawm 1{{5}butene lossis isobutylene. Nyob rau hauv polyurethane foaming, cov olefins nrog ob daim ntawv cog lus yog heev reactive thiab yuav sai sai noj cov amine catalysts nyob rau hauv lub system, ua rau cov foaming cov ntaub ntawv lub sij hawm mus rau lengthen, nws thiaj li ua rau npuas tawg. Raws li rau sulfides, txawm 2-3 ppm ntawm hydrogen sulfide los yog mercaptans nyob rau hauv n-butane yuav hnov mob nrog tooj liab hlab nyob rau hauv lub tub yees system los ua cuprous sulfide, uas deposits nyob rau hauv lub valve daim hlau, ua rau lub compressor poob nws lub foob thiab tag nrho scrapped. Yog li ntawd, thaum muas n-butane, koj tab tom yuav "tswj tshaj impurities," tsis yog tus lej purity xwb.
Ntawm ntau cov n-butane manufacturers, ZL Zog, los ntawm kev tsim txiaj ntawm nws txoj kev sib sib zog nqus distillation teeb meem, tau ua tiav qhov kev txo qis qhov kev tawm tsam ntawm kev tswj kom zoo tshaj qhov ntsuas impurity.
Muaj ntau lub khw muag khoom hauv khw uas tuaj yeem ua kom huv n-butane mus rau 99%, tab sis ob peb tus tuaj yeem tshem tawm cov dej noo thiab mercaptans. Qhov no coj peb mus rau ZL Energy qhov tseem ceeb barrier.
Raws li tus kws tshaj lij cov chaw tsim khoom ntawm n-butane, ZL Zog nkag siab tob txog qhov mob ntawm cov neeg siv khoom siab- kawg. Kev sib cais ntawm C4 Cheebtsam, tshwj xeeb tshaj yog kev tshem tawm tag nrho ntawm n-butane los ntawm isobutane thiab tshem tawm cov kab sulfides, yuav tsum muaj cov kab sib cais siab heev. ZL Zog, vam khom rau nws cov qib siab siab -kev ua tau zoo distillation units nrog ntau pua lub tais thiab cov khoom muaj ntau-theem desulfurization thiab lub cev qhuav dej, tuaj yeem "rub tawm los ntawm cov hauv paus hniav" isobutane, olefins, thiab cov dej thiab sulfur impurities los ntawm n-butane.
Los ntawm ZL Energy lub precision purification, purity ntawmn-ButaneTsis tsuas yog tsis tu ncua ntau tshaj 99.5%, tab sis tseem ceeb tshaj, tag nrho cov ntsiab lus sulfur yog suppressed hauv qab no 1 ppm, thiab cov ntsuas dej noo nyob deb ntawm lub teb chaws tus qauv, kom tshem tawm tag nrho cov impurities xws li olefins. Xaiv ZL Zog rau cov khoom siv ncaj qha txhais tau tias koj tsis yog yuav n-butane xwb, tab sis kuj tseem muaj kev tswj hwm nruj ntawm cov chaw tsim khoom. Qhov no ua rau koj cov txheej txheem foaming ruaj khov dua, koj lub tub yees muaj kev nyab xeeb dua, thiab txuag tsis yog tus neeg nruab nrab markup, tab sis kuj muaj kev sim siab siab -thiab- cov nqi yuam kev.
