Propylene oxideFeem ntau yog siv hauv kev tsim cov polyether polyols. Polyether polyol yog muab los ntawm propylene oxide, cov khoom siv organic uas muaj ob lossis ntau pawg hydroxyl, thiab qee hom polyether muaj micron-loj ncua kev kawm ntawm cov khoom siv hluav taws xob. propylene oxide yog cov tshuaj lom, yog li cov ntsiab lus hauv qab no yuav tsum tau muab sau tseg thaum ua haujlwm.

Kev nyab xeeb ntawmPropylene oxidekev ua haujlwm
(1) Thaum qhib lub propylene oxidecontainer, xyuas kom meej tias thaj chaw ua haujlwm yog qhov cua zoo thiab tsis muaj qhov hluav taws xob lossis qhov hluav taws kub; zam kom tsis txhob cia cov vapor tso tawm hauv huab cua hauv thaj chaw ua haujlwm. Lub rooj cob qhia rau kev tsim khoom thiab khaws cia ntawm propylene oxide yuav tsum muaj kev tiv thaiv hluav taws zoo thiab tiv thaiv tawg. Thaum hluav taws kub, qhuav hmoov tua hluav taws, carbon dioxide tua hluav taws thiab xuab zeb yuav tsum tau siv los tua hluav taws.
(2) Thaum lub propylene oxide system xau, sawv ntsug ntawm qhov nkag nkag thiab hnav lub npog ntsej muag roj zoo tib lub sijhawm ua haujlwm.
(3) Ua kom cov dej siab thiab roj siab ntawm cov cuab yeej zoo li qub thiab cov kav dej sib txuas yuav tsum du. Khaws cov khoom siv thiab tshem tawm cov phenomena ntawm kev khiav, bubbling, dripping thiab to, kom cov khoom nyob rau hauv zoo.
(4) thaj chaw tsim khoom, qhib hluav taws thiab tuaj yeem tsim hluav taws qhib, kev ua haujlwm ntawm lub txim raug txwv nruj heev. Cov kev xav tau ntau lawm los yog thaum lub sij hawm tu yuav tsum tau pib qhov hluav taws kub, yuav tsum mus rau cov txheej txheem kev pom zoo hluav taws.
(5) Kev ntxuav cov dej phwj tuaj ntawm cov cuab yeej tsim khoom thiab cov dej ntxuav hauv pem teb ntawm qhov chaw tsim khoom yuav tsum tau muab tso rau hauv lub pas dej thaum muaj xwm ceev thiab tsuas yog tom qab kev kho mob tsim nyog.
Cia kev nyab xeeb ntawmPropylene oxide
Vim tias cov yam ntxwv ntawm propylene oxide thiab qhov tsis zoo ntawm cov qauv kev khaws cia, xws li kev ua pa tsis ua pa, ib puag ncig muaj kuab lom thiab hluav taws kub thiab tawg, cov txheej txheem khaws cia tau siv txoj kev kaw cia thiab cov thev naus laus zis tshiab ntawm kev kaw cia los ntawm cov khoom ntawm kev cia, kev thauj khoom thiab unloading, kub tswj, tank tsim, xaiv cov khoom siv thiab tiv thaiv hluav taws thiab tawg. Tom qab kev ua tiav ntawm kev ua haujlwm kaw, qhov poob ntawm propylene oxide hauv cov txheej txheem khaws cia thiab cov pa phem rau ib puag ncig raug txo, thiab kev ruaj ntseg cia thiab tuav tau ua kom ntseeg tau,
(1) propylene oxideis khaws cia rau hauv qhov chaw txias, zoo-ventilated warehouse tshwj xeeb los yog cia tank, kom deb ntawm qhov hluav taws kub thiab cua sov. Qhov kub ntawm chav cia khoom yuav tsum tsis txhob siab tshaj 29 ℃ thiab khaws lub thawv kaw.
(2) propylene oxide yuav tsum tau muab cais los ntawm oxidizers, acids, alkali hlau, thiab lwm yam., tsis txhob sib tov cia. Siv cov khoom tawg-pov thawj teeb pom kev zoo thiab qhov cua qhov cua. Txwv tsis pub siv cov tshuab hluav taws xob thiab cov cuab yeej siv hluav taws xob. Lub chaw cia khoom yuav tsum tau nruab nrog cov cuab yeej kho mob xwm txheej ceev rau cov dej xau thiab cov khoom siv vaj tse tsim nyog. Teem cofferdam nyob ib ncig ntawm lub propylene oxidestorage tank, qhov ntim ntawm uas yog sib npaug rau lub ntim ntawm lub tank cia.
(3) Ua tib zoo saib xyuas kev tiv thaiv xob laim thiab tiv thaiv zoo li qub. Cov tso tsheb hlau luam hauv cov nroj tsuag yuav tsum tau nruab nrog kev tiv thaiv hluav taws xob thiab cov chaw tiv thaiv zoo li qub raws li cov cai ntawm Txoj Cai rau Kev Tiv Thaiv Kev Tiv Thaiv Kev Tsim Vaj Tsev.
Shaanxi BLOOM TECH Co., Ltd tsim Propylene oxideat tus nqi pheej yig. Lub tuam txhab nrog cov cuab yeej thev naus laus zis, thawj cov khoom lag luam, cov kev pabcuam thawj zaug, thiab feem ntau ntawm cov neeg siv khoom sib koom tes. Nrog lub zog ntawm kev siv technology tshiab.
