Kev Tshawb Fawb Txog Cov Ntawv Thov Tshwj Xeeb ntawm Iav Fiber hauv Cov Khoom Siv Tshuaj Graphite

1. Daim Ntawv Thov ntawm Iav Fiber hauv Graphite Chemical Reactors thiab Lwm Yam Khoom Siv

Daim ntawv thov tseem ceeb ntawm cov iav fiber hauv cov khoom siv tshuaj graphite yog ua cov khoom siv txhawb nqa los txhim kho cov khoom siv kho tshuab thiab kev tiv thaiv corrosion ntawm graphite. Lub hauv paus ntsiab lus yog tias txawm hais tias graphite muaj kev tiv thaiv cua sov zoo thiab kev coj hluav taws xob, nws cov khoom siv kho tshuab thiab kev tiv thaiv corrosion tsis muaj zog. Yog li ntawd, ntxiv cov iav fiber tuaj yeem txhim kho cov "khoom siv tsis muaj zog" qub ntawm cov khoom siv tshuaj graphite. Tshwj xeeb: Graphite yog cov khoom siv reactor zoo tagnrho vim tias nws muaj kev tiv thaiv cua sov zoo thiab kev coj hluav taws xob, thiab kev ruaj khov tshuaj zoo tiv thaiv feem ntau cov tshuaj. Txawm li cas los xij, cov khoom siv kho tshuab ntawm graphite ntshiab tsis zoo tagnrho, tshwj xeeb tshaj yog thaum raug kev cuam tshuam thiab kev co. Lub zog tensile ntawm iav fiber yog 3450 ÷ 10 ~ 20 = 345 ~ 172.5 npaug ntau dua li ntawm graphite. Ntxiv cov iav fiber ua cov khoom siv txhawb nqa rau graphite tuaj yeem txhim kho cov khoom siv kho tshuab ntawm lub reactor. Ntxiv mus, iav fiber muaj kev tiv thaiv corrosion zoo rau feem ntau cov kua qaub, alkalis, thiab cov kuab tshuaj. Yog li ntawd, txawm hais tias graphite nws tus kheej muaj kev ruaj khov zoo tiv thaiv feem ntau cov tshuaj, iav fiber yuav muab kev tiv thaiv corrosion muaj zog dua hauv qee qhov kub thiab siab siab. Piv txwv li, hauv kev tsim cov kua qaub sulfuric hauv cov nroj tsuag tshuaj lom neeg, siv lub reactor nrog lub graphite lining thiab lub iav fiber composite plhaub. Vim tias cov txheej txheem tsim cov kua qaub sulfuric acid muaj qhov kub thiab txias siab, thiab yog corrosive heev rau cov khoom siv, cov khoom siv ntawm lub reactor yog qhov tseem ceeb. Cov reactors siv cov khoom sib xyaw no tsis yog tsuas yog muaj kev tiv thaiv corrosion zoo heev, tab sis kuj tseem txhim kho cov khoom siv kho tshuab vim yog kev txhawb nqa nrog iav fiber, ua rau muaj kev nyab xeeb thiab txhim khu kev qha. Raws li cov ntaub ntawv Hoobkas, lub neej ua haujlwm ntawm lub reactor no ntau dua ob npaug ntawm cov hlau reactors ib txwm muaj. Ntxiv mus, graphite reactors txhawb nqa nrog iav fiber muaj lwm yam zoo. Piv txwv li, vim yog qhov coefficient qis ntawm thermal expansion ntawm iav fiber, qhov loj me ntawm lub reactor hloov me ntsis ntawm qhov kub siab, uas pab tswj cov xwm txheej tshuaj tiv thaiv ruaj khov. Ntxiv mus, vim yog tus nqi qis ntawm iav fiber, tag nrho tus nqi ntawm cov khoom sib xyaw no qis dua ntau lwm hom reactors. Dhau li ntawm cov tshuaj reactors, lub hauv paus ntsiab lus ntawm kev ntxiv cov khoom siv iav fiber hauv kev npaj cov khoom siv yeeb nkab graphite, graphite cua sov exchangers thiab lwm yam khoom siv tshuaj lom neeg zoo sib xws, txhua lub hom phiaj ntawm kev them nyiaj rau qhov tsis muaj zog ntawm cov khoom siv graphite hauv cov nqe lus ntawm cov khoom siv kho tshuab.

2. Kev Tshawb Fawb Txog Cov Txheej TxheemDaim Ntawv Thov Iav Fiberhauv Cov Khoom Siv Tshuaj Graphite

Feem ntau muaj ob txoj hauv kev rau kev siv cov ntaub ntawv iav fiber hauv cov khoom siv tshuaj graphite.

(1) Ntsug winding. Qhov zoo ntawm cov txheej txheem no yog:Ua ntej, nws ua kom yooj yim rau cov txheej txheem tsim khoom vim tias cov khoom siv tuaj yeem raug qhwv rau hauv nws qhov chaw ua haujlwm kawg. Qhov thib ob, rau cov khoom siab, nyias, xws li cov kem lossis cov kav dej, cov xov ntsug yog qhov tsim nyog dua vim tias nws tuaj yeem muab kev sib npaug zoo dua thiab kev sib npaug. Qhov thib peb, nws tuaj yeem ua tiav cov txheej txheem tsim khoom tas mus li, yog li txhim kho kev ua haujlwm ntau lawm. Qhov tsis zoo yog: Ua ntej, rau cov khoom loj lossis hnyav, cov qauv txhawb nqa ntxiv yuav tsum tau ua kom lawv ruaj khov thaum lub sijhawm ua haujlwm winding; qhov thib ob, ntau qhov chaw hauv pem teb yuav tsum tau ua vim tias cov khoom siv yuav tsum tau qhwv rau hauv qhov chaw ntsug; qhov thib peb, rau qee qhov duab nyuaj, cov xov ntsug yuav tsis yooj ywm li cov xov kab rov tav;

(2) Kab rov tav winding. Qhov zoo ntawm cov txheej txheem no yog:Ua ntej, rau cov khoom loj lossis hnyav, cov winding kab rov tav muab kev ruaj khov zoo dua yam tsis tas yuav muaj cov qauv txhawb nqa ntxiv; qhov thib ob, cov winding kab rov tav tuaj yeem hloov kho rau cov duab ntawm cov khoom sib txawv vim nws tuaj yeem cua mus rau ntau qhov kev taw qhia; qhov thib peb, cov winding kab rov tav ua rau kev thauj khoom thiab kev teeb tsa khoom siv yooj yim dua vim tias cov khoom tuaj yeem ntim thiab thauj mus rau hauv qhov chaw kab rov tav. Qhov tsis zoo yog: Ua ntej, rau cov khoom siab, nyias, cov winding kab rov tav yuav ua rau cov winding tsis sib xws, cuam tshuam rau qhov sib npaug thiab kev sib npaug ntawm cov khoom; qhov thib ob, cov kauj ruam ua haujlwm ntawm cov winding kab rov tav yog qhov nyuaj dua, xws li hloov cov khoom los ntawm ntsug mus rau qhov chaw kab rov tav, uas yuav cuam tshuam rau kev ua haujlwm ntau lawm.

Feem ntau, thaum thovcov ntaub ntawv iav fiberHauv cov khoom siv tshuaj graphite, cov txheej txheem winding yuav tsum tau xaiv raws li qhov xwm txheej tiag tiag. Lub hom phiaj kawg yog siv tag nrho cov kev ua tau zoo ntawm cov ntaub ntawv iav fiber thiab them rau qhov tsis zoo ntawm cov ntaub ntawv graphite.
