Yuav ua li cas yog PTFE Exchangers siv nyob rau hauv zus tau tej cov High-Purity Hydrogen Peroxide?

Hydrogen peroxide yog lub zog oxidiser thiab yooj yim decomposes nyob rau hauv lub xub ntiag ntawm hlau ions, tshwj xeeb tshaj yog hlau, tooj liab thiab chromium. Kev tsim khoom thiab kev ua haujlwm ntawm high purity peroxide yuav tsum tau ua nrog nruj kev zam ntawm cov hlau tsis huv. Txhua qhov chaw ntub dej ntawm cov khoom siv hluav taws xob rau cov kev pabcuam no yuav tsum tsis txhob muaj cov hlau tsis muaj peroxide thiab ua kom cov khoom ruaj khov.

Kev npaj ntawm Hydrogen Peroxide
Hydrogen peroxide feem ntau yog ua los ntawm kev siv cov txheej txheem anthraquinone uas cuam tshuam nrog hydrogenation, oxidation thiab dej extraction. Ua ntej, anthraquinone yog hydrogenated los tsim anthrahydroquinone. Qhov no yog tom qab oxidized nrog oxygen rau hydrogen peroxide. Cov tshuaj peroxide tau muab rho tawm mus rau hauv ib theem dej, tom qab ntawd cov concentrated thiab lim kom tshem tawm cov kuab tshuaj organic thiab cov kab mob.

Hydrogen peroxide yog qhov rhiab heev rau kev sib kis ntawm cov hlau thiab kev ruaj ntseg ntawm cov tshuaj peroxide yuav tsum tau tswj xyuas thaum lub sijhawm ua haujlwm no. Cov qib me me ntawm cov hlau kuj tseem tuaj yeem ua rau kev puas tsuaj, uas cuam tshuam rau purity thiab kev ua tau zoo ntawm cov khoom. Yog li, cov khoom siv hluav taws xob ua haujlwm hauv cov txheej txheem no yuav tsum tsis txhob ntxiv cov hlau rau cov tshuaj peroxide.

Wärmetauscher nyob rau hauv der Wasserstoffperoxidherstellung
Thaum tshav kub kub exchangers yog ua hauj lwm thoob plaws hauv cov txheej txheem ntawm hydrogen peroxide tsim los tswj kub ntawm ob peb txheej txheem ntws. Cov no suav nrog kev ua kom txias ntawm cov kuab tshuaj organic, cua sov ntawm kev ua haujlwm, thiab kev tswj qhov kub thiab txias ntawm aqueous hydrogen peroxide daws. Qhov kub rhiab heev ntawm hydrogen peroxide txhais tau hais tias cov khoom siv hluav taws xob ua haujlwm nyob rau hauv cov txheej txheem no yuav tsum tsis txhob ua rau lub degradation ntawm peroxide.

Qhov zoo dua hauv daim ntawv thov no yog cov fluoropolymer heat exchangers, tshwj xeeb tshaj yog cov uas muaj PTFE (polytetrafluoroethylene) los yog PFA (perfluoroalkoxy). Lawv muab tag nrho cov hlau tsis muaj cua sov hloov chaw, tshem tawm txhua yam kev phom sij ntawm cov hlau ion paug thiab yog li tswj xyuas peroxide stability. Tsis tas li ntawd, PTFE thiab PFA yog impervious rau cov organic solvents ua hauj lwm nyob rau hauv cov txheej txheem thiab peroxide nws tus kheej, kom ntseeg tau ntev -lub sij hawm kev cia siab thiab kev ua tau zoo.

### Qhov xav tau rau PTFE cua sov exchangers hauv hydrogen peroxide ntau lawm ###
Cov hauv qab no yog cov laj thawj rau kev siv dav ntawm PTFE thiab PFA exchangers hauv kev tsim cov hydrogen peroxide:

Hlau -Dawb Nto PTFE thiab PFA tshav kub exchangers muab tag nrho cov hlau-dawb nto uas yog ib qho tseem ceeb los tiv thaiv peroxide tawg catalysed los ntawm cov kab ntawm cov hlau ions xws li hlau los yog tooj liab.

Kev tiv thaiv rau Organic Solvents thiab Peroxide: Ob leeg PTFE thiab PFA yog resistant rau qhov loj spectrum ntawm organic solvents siv nyob rau hauv cov txheej txheem anthraquinone thiab rau hydrogen peroxide. Qhov no ua rau cov ntaub ntawv zoo tshaj plaws los tswj kev ruaj ntseg ntawm cov khoom thoob plaws hauv lub voj voog ntau lawm.

High Purity: PTFE thiab PFA yog cov kev pabcuam peroxide tau lees paub, yog li cov neeg sib pauv ua tiav cov txheej txheem purity nruj. Lawv tau tsim los tswj cov qib siab tshaj plaws ntawm cov tshuaj lom neeg thiab kom tsis txhob muaj kev sib kis.

Temperature Stability: PTFE heat exchangers rau peroxide lub luag hauj lwm feem ntau muaj qhov kub siab tshaj plaws hauv qab 100 degree, txawm li cas los xij PFA cov khoom siv hluav taws xob tuaj yeem ua haujlwm ntawm qhov kub ntau dua thiab siv rau hauv daim ntawv thov hnyav dua.

Fluoropolymer exchangers yog tus qauv ntawm kev lag luam rau cov hlau txhim khu kev qha -dawb tshav kub hloov hauv hydrogen peroxide ntau lawm.

Kev txiav txim siab
Decomposition Sensitivity: Hloov cov hlau catalyze decomposition ntawm hydrogen peroxide ntawm qhov ntau ntawm qhov chaw ib billion (ppb). Cov khoom siv purity yog qhov tseem ceeb vim tias txawm tias me ntsis paug nrog cov hlau ions tuaj yeem ua rau poob qis ntawm peroxide stability.

Kev txwv kub: PTFE muaj peev xwm tiv taus qhov kub txog li 110℃uas yog qhov siv tau rau feem ntau cov ntawv thov hydrogen peroxide. Txawm li cas los xij PFA exchangers raug xaiv rau qhov yuav tsum tau kub siab dua vim nws muaj qhov kub thiab txias dua.

Cov txheej txheem purity: PTFE thiab PFA ua raws li cov txheej txheem purity nruj tsim nyog rau kev tsim cov purity siab hydrogen peroxide. Lawv tiv taus hydrogen peroxide thiab yuav tsis ntxiv cov pa phem uas yuav cuam tshuam rau qhov zoo ntawm cov khoom.

Purity Note
Ua ntej tshiab fluoropolymer exchangers raug muab tso rau hauv kev pab cuam rau hydrogen peroxide ntau lawm lawv yuav tsum tau passivated kom zoo thiab ntxuav kom tshem tawm cov residues thiab impurities uas yuav cuam tshuam purity. Cov txheej txheem no tseem ceeb heev rau cov neeg sib pauv kom muaj peev xwm ua tau raws li cov qauv tsim nyog rau cov hlau - kev pabcuam dawb nrog rau kev ruaj ntseg ntawm peroxide.

Cov lus xaus
Hlau -dawb tshav kub hloov chaw muab los ntawm PTFE cov khoom siv hluav taws xob yuav tsum tau txo qis qhov muaj peev xwm ntawm cov hlau ion paug nyob rau hauv lub cim ruaj khov, siab - purity hydrogen peroxide. Cov khoom sib pauv no tseem ceeb rau kev khaws cov tshuaj peroxide kom ruaj khov thiab tswj xyuas cov khoom zoo.

Fluoropolymer exchangers yog qhov tseem ceeb rau kev sib txuas ntawm hydrogen peroxide, vim tias cov khoom siv purity yog qhov tseem ceeb heev rau kev ruaj ntseg ntawm cov khoom sib txuas. Cov tshuaj tiv thaiv thiab purity ntawm cov ntaub ntawv siv yuav tsum yog thawj qhov tseem ceeb kom tau txais cov txiaj ntsig zoo thiab cov khoom zoo tshaj plaws.
