Cov tshuaj tiv thaiv tshuaj, uas tshwm sim vim qhov kub thiab txias siab dua li ntawm 260 ° C / 200 bars, yog cov ntawv thov uas Berghof reactors tau tsim.Qhov tshwj xeeb ntawm Berghof reactors yog lawv qhov tshwj xeeb, tuab PTFE liner.Tag nrho cov khoom, uas tuaj rau hauv kev sib cuag nrog cov kua xov xwm, yog ua los ntawm PTFE los yog lawv coated nrog ib tug fluoropolymer.
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 cov kev tiv thaiv zoo heev rau yuav luag txhua yam tshuaj, uas ua rau nws ua tau yam tsis muaj ntau yam khoom kim heev tshwj xeeb, xws li hastelloy.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 ua raws li cov hlau reactors thiab nyuaj heev 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 ib tug PTFE liner rau txhua hom catalyser.Tip: Lub PTFE liners kuj yuav siv tau raws li cov tswv yim cia nkoj rau reactive daws.
Universal siv
Berghof 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 Berghof Cheebtsam tsis ua.Cov PTFE Cheebtsam no tsis muaj cov kev taw qhia zoo dua vim tias, ua tsaug rau isostatic compression-molding txoj kev tsim los ntawm Berghof tsis muaj kev xav tau thiab paub qhov txawv ntawm lawv tus kheej los ntawm tib qho kev nthuav dav coefficients nyob rau hauv tag nrho cov lus qhia 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 mus rau cov tshuaj, txawm rau aggressive acids thiab alkali→Tsis-corrosive→Tsis muaj kab mob
Isostatic compression molding
covB Thaum cov pa, ib leeg-axis compression molding txoj kev yog siv, raws li txoj cai, cov khoom yog compressed vertically nyob rau hauv lub pwm nrog ib tug quab yuam plug.Tsis muaj kab rov tav compression crosswise mus rau compression kev taw qhia.Los ntawm qhov sib txawv, nyob rau hauv cov txheej txheem isostatic compression-molding lub zog yog siv rau cov khoom sib npaug thiab ib txhij los ntawm txhua qhov kev qhia hauv qhov chaw ntawm qhov nruab nrab hydraulic thiab compresses nws homogeneously.Yog li kev pom zoo compression tiav, ua rau muaj qhov porosity tsawg, qhov zoo ntawm cov qauv thiab qhov siab tshaj plaws tensile thiab compression zog.Tsis muaj cov lus qhia nyiam raug tsim thiab cov khoom siv isotropic khaws cia.Tshwj xeeb tshaj yog lub tensile thiab compression lub zog ntawm cov khoom yog zoo ib yam nyob rau hauv tag nrho cov lus qhia nyob rau hauv qhov chaw.
Zoo zoo ua tsaug rau isostatic compression molding
Qhov zoo ntawm isostatic compression molding tuaj yeem pom los ntawm kev nthuav dav REM cov duab tsim nyog.Thaum magnified 100 npaug ntawm cov granulate hais ntawm cov khoom qub tseem tuaj yeem txheeb xyuas hauv PTFE yog tias nws tau raug rau ib leeg-axis compression molding.Los ntawm qhov sib txawv, isostatically compression-molded PTFE qhia tau hais tias muaj qhov sib txawv ntawm cov qauv zoo sib xws.Nws yog roughly sib npaug rau ib leeg-axis compression-molded TFM ™ PTFE.Txawm li cas los xij isostati-cally compression-molded TFM™ PTFE ua tiav cov qauv zoo dua thiab du dua.Tsis tas li ntawd, thaum magnified 2,500 lub sij hawm, nyob rau hauv ib leeg-axis compression-moulded khoom flaws yuav pom, uas tsis tshwm sim nyob rau hauv isostatically compression-molded TFM™ PTFE.
