Oxygen absorbents, raws li cov tshuaj siv tshuaj uas tshem tawm cov pa oxygen los ntawm qhov chaw nyob ib puag ncig, yog siv dav hauv kev khaws zaub mov, ntim tshuaj, thiab kev tiv thaiv hluav taws xob. Lawv cov txheej txheem ntau lawm suav nrog ntau theem, suav nrog kev npaj cov khoom siv raw, sib xyaw thiab cov tshuaj tiv thaiv, molding thiab ziab, thiab tshuaj xyuas zoo. Txhua kauj ruam yuav tsum tau nruj tswj xyuas kom muaj kev ruaj ntseg thiab kev ntseeg siab ntawm cov khoom ua tau zoo.
Kev npaj raw khoom
Cov khoom tseem ceeb ntawm cov pa oxygen absorbent feem ntau suav nrog txo cov hmoov hlau, cov pa roj carbon activated, sodium chloride (los yog calcium chloride), thiab cov khoom siv xws li lub ntiaj teb diatomaceous. Txo cov hmoov hlau yog cov tub ntxhais reactant, ua tiav cov pa nqus pa los ntawm cov tshuaj tiv thaiv oxidation nrog oxygen; activated carbon disperses cov hmoov hlau thiab txhawb cov roj diffusion; sodium chloride los yog calcium chloride ua raws li catalyst, ua kom cov txheej txheem oxidation ntawm hlau; thiab diatomaceous lub ntiaj teb yog siv los tswj cov tshuaj tiv thaiv tus nqi thiab txhim kho lub cev ntawm cov khoom sib tov.
Hauv kev npaj cov khoom siv raw, tag nrho cov khoom siv raw yuav tsum tau kuaj xyuas nruj thiab ua ntej. Hlau hmoov yuav tsum ua tau raws li cov qauv purity kom tsis txhob muaj impurities cuam tshuam rau kev ua haujlwm ntawm cov tshuaj tiv thaiv; activated carbon xav tau kev kho kom ua kom zoo dua adsorption; Lwm cov khoom siv pabcuam yuav tsum raug ntsuas kom raug raws li qhov sib npaug kom ntseeg tau tias cov khoom kawg lub peev xwm nqus pa oxygen raws li cov qauv.
Kev sib xyaw thiab tshuaj tiv thaiv
Raw khoom sib tov yog ib qho ntawm cov kauj ruam tseem ceeb hauv kev tsim cov pa oxygen absorbers. Weighed hlau hmoov, activated carbon, sodium chloride, thiab diatomaceous lub ntiaj teb yog ntxiv rau ib tug sib tov khoom raws li ib tug tshwj xeeb piv thiab mechanically stirred los xyuas kom meej kev faib ua feem. Thaum sib tov, qhov ceev thiab lub sij hawm yuav tsum tau tswj kom tsis txhob dhau - stirring, uas yuav ua rau particle agglomeration los yog pib ntxov ntxov.
Qee cov txheej txheem tsim khoom siv cov kauj ruam-los ntawm- cov kauj ruam sib xyaw ua ke, qhov twg cov pa roj carbon monoxide thiab sodium chloride tau sib xyaw ua ntej ua ntej ntxiv cov hmoov hlau thiab lwm yam tshuaj ntxiv los ua kom zoo dua. Cov ntaub ntawv sib xyaw ua ke feem ntau yog nyob rau hauv daim ntawv xoob xoob, muaj huab cua zoo permeability thiab thaj chaw tiv thaiv, tso lub hauv paus rau cov kev tshwm sim tom ntej.
Shaping thiab ziab
Cov khoom sib xyaw ua ke yuav tsum tau ua raws li qhov xav tau ntawm daim ntawv thov. Cov txheej txheem shaping feem ntau suav nrog cov ntsiav tshuaj, granulation, lossis ncaj qha sau rau hauv cov hnab ntim cov pa. Tableting yog tsim rau cov pa oxygen absorbers uas yuav tsum tau ib tug taag zoo, thaum granulation txhim kho flowability thiab filling uniformity. Rau me me - cov ntawv ntim ntim, ncaj qha sau cov hmoov sib xyaw rau hauv cov pa uas tsis yog- woven hnab yog ntau dua.
Yog tias cov pa oxygen absorber muaj qee qhov dej noo, nws yuav tsum tau qhuav kom ntev nws lub txee lub neej thiab ua kom cov tshuaj tiv thaiv kev ruaj ntseg. Kev ziab kub yog feem ntau tswj nyob rau hauv thaj tsam ntawm 40-60℃los tiv thaiv oxidation ntxov ntxov ntawm cov hmoov hlau vim qhov kub thiab txias. Cov khoom qhuav yuav tsum tau muab cia rau hauv lub thawv kaw kom tiv thaiv kom tsis txhob ya raws thiab ua kom pom kev ua haujlwm zoo.
Kev xeem zoo thiab ntim khoom
Ua tiav cov pa oxygen absorbers tau kuaj xyuas kom zoo, suav nrog kev ntsuas kev nqus pa oxygen, kev txiav txim siab tus nqi, thiab ntsuas cov dej noo. Oxygen absorption muaj peev xwm raug soj ntsuam los ntawm simulating oxygen noj nyob rau hauv ib qho chaw kaw kom ua raws li cov qauv kev lag luam; Cov tshuaj tiv thaiv tus nqi kuaj xyuas cov khoom ua tau zoo nyob rau hauv lub hom phiaj kub thiab av noo; thiab cov ntsiab lus noo noo yuav tsum nruj me ntsis tswj kom qis qis kom tsis txhob deterioration thaum khaws cia.
Cov khoom tsim nyog tau muab ntim rau hauv aluminium-cov hnab yas sib xyaw lossis cov khoom ntim nrog cov khoom siv oxygen los tiv thaiv kev nkag mus ntawm sab nraud thiab cov pa oxygen, uas tuaj yeem ua rau ua tsis tiav ntxov. Qee cov khoom siv siab- kawg kuj suav nrog cov av noo lossis cov pa oxygen rau cov neeg siv kom pom qhov pom ntawm qhov nqus dej.
Cov txheej txheem tsim cov pa oxygen absorbers koom nrog ntau yam kev qhuab qhia, suav nrog cov ntaub ntawv tshawb fawb, tshuaj lom neeg engineering, thiab kev tswj kom zoo. Nws lub hauv paus yog nyob rau hauv kev ua kom muaj kev ruaj ntseg thiab kev ua haujlwm ntawm cov hlau -raws li cov tshuaj tiv thaiv. Los ntawm kev xaiv cov khoom siv raw khoom nruj, kev tswj hwm kev faib ua feem, thiab kev tswj hwm kev tsim khoom, txhim khu kev qha thiab ntau yam khoom siv oxygen absorbent thaum kawg yog tsim los ua kom tau raws li kev khaws cia thiab kev tiv thaiv kev xav tau ntawm ntau yam kev lag luam. Nyob rau hauv lub neej yav tom ntej, nrog cov kev cai ib puag ncig nruj zuj zus, qis -zog- siv thiab biodegradable oxygen absorbent txheej txheem yuav dhau los ua qhov tseem ceeb ntawm kev tshawb fawb thiab kev tsim kho, ntxiv dag zog rau kev nce qib hauv daim teb no.
