Kev kub siab reactors Cim PTFE liner rau reactors

Kev kub siab reactors Reactor liners ua los ntawm PTFE lav kev pom zoo rau cov tshuaj.

cov

Corrosion tiv thaiv suav nrog

PTFE liner, uas yog ob peb millimeters tuab, tiv thaiv stainless hlau reactor zoo tiv thaiv corrosion, txawm tawm tsam xws li corrosive media li acids thiab alkali.PTFE yog qhov txawv los ntawm nws zoo heev tiv thaiv yuav luag tag nrho cov tshuaj, uas ua rau nws ua tau tsis muaj ntau kim tshwj xeeb alloys.Qhov no ua rau txo cov nqi yuav khoom.

Qhov kev pheej hmoo ntawm cov kab mob sib kis tau yooj yim dua los tswj nrog PTFE liners.Hlau catalysers, xws li Pt, Rh, Raney Nickel thiab lwm yam adheres rau steel reactors thiab yog heev nyuaj rau tshem tawm.Hauv cov kev sim hauv qab no cov lus nug yuav ua rau qoob loo yog tias cov txiaj ntsig tau pom tiag tiag tshwm sim los ntawm kev hloov pauv ntawm catalyser, cuam tshuam los yog catalyst lom.Qhov teeb meem no yog elegantly evaded los ntawm reserving PTFE liner rau txhua hom catalyser.

Tswv yim: Cov PTFE liners kuj tseem siv tau los ua cov khoom siv cia rau cov kev daws teeb meem.

Universal siv

Kev kub siab reactors tuaj yeem siv rau txhua lub hom phiaj;tag nrho cov khoom uas tuaj rau hauv kev sib cuag nrog cov kua theem yog tiv thaiv tshuaj tua kab mob los ntawm fluoropolymer.Lub liner yog hermetically kaw thiab clings rau sab hauv ntawm lub reactor phab ntsa zoo li daim tawv nqaij.Li no nws txawv heev ntawm PTFE liners, uas tau muab tso rau hauv lub reactor.Tag nrho cov liner muaj xws li tshem tau PTFE ntxig, lub hau hauv ob sab phlu, lub dip yeeb nkab thiab agitator sheaths thiab PTFE sealing rings.Tag nrho cov khoom no tuaj yeem raug tshem tawm thiab rov txuas tau yooj yim rau kev ntxuav.Lub thickness ntawm phab ntsa ntawm lub liner nyob ntawm lub reactor ntim thiab thaj tsam ntawm 1.6 thiab 7.4 hli.Lub hauv ob sab phlu yog tsawg kawg yog 3.7 hli tuab.Qhov siab tshaj plaws kev khiav hauj lwm siab ntawm lub reactors yog 200 bars thiab qhov siab tshaj plaws kub rau kev khiav hauj lwm tas mus li yog 230 ° C.Rau ib lub sij hawm luv luv (xws li max. 60 min) lub reactor kuj tuaj yeem ua kom sov txog 260 ° C.Siab dua tempera-tures thiab ntev cua sov theem siab tshaj 260 ° C puas PTFE liner.

Raws li cov kev khiav hauj lwm kub kub, cov pa PTFE cov khoom ua "distorted";tab sis qhov kub siab reactors Cheebtsam tsis.Cov PTFE Cheebtsam no tsis muaj cov kev taw qhia nyiam vim hais tias, ua tsaug rau isostatic compression-molding txoj kev tsim los ntawm kev kub siab reactors tsis nyiam cov kev taw qhia thiab txawv lawv tus kheej los ntawm tib expansion coefficients nyob rau hauv tag nrho cov lus qhia nyob rau hauv qhov chaw.Ib qho "distortion" ntawm qhov chaw, txawm tias nyob rau ntawm qhov kub thiab txias siab yog li tsis suav nrog.

Qhov zoo ntawm PTFE-hauv ob sab phlu:

* Siab tempering lub zog, luv luv mus txog +260 ° C * Siab-nruj mus txog 200 bars * Universal tsis kam rau tshuaj, txawm mus rau aggressive acids thiab alkali * Tsis-corrosive * Tsis muaj paug
