Cleaning ib 20Liav reactoryuav tsum tau ua tib zoo xyuas kom nws tsis muaj cov kab mob thiab cov seem uas yuav cuam tshuam rau cov kev sim tom ntej. Nov yog ib txoj kev tu kom zoo:
Kev Tiv Thaiv Kev Nyab Xeeb:Ua ntej pib, xyuas kom koj hnav cov khoom tiv thaiv tus kheej tsim nyog (PPE) xws li hnab looj tes thiab tsom iav kev nyab xeeb.
Disassembly:Yog tias ua tau, disassemble lub iav reactor rau hauv nws tus kheej cov khoom. Qhov no pab txhawb kev tu kom huv dua los ntawm kev tso cai nkag mus rau txhua qhov chaw.
Ua ntej yaug:Yaug lub reactor thiab nws cov khoom nrog dej sov kom tshem tawm cov khib nyiab los yog cov seem.
Degreasing:Siv cov tshuaj degreasing uas tsim nyog los tshem tawm cov roj lossis roj seem ntawm cov iav. Siv lub degreaser raws li cov chaw tsim khoom cov lus qhia thiab cia nws so rau lub sijhawm pom zoo.
Kev ntxuav tu:Npaj cov tshuaj ntxuav uas siv cov tshuaj ntxuav me me los yog lub chaw kuaj mob tshwj xeeb iav tshuab ntxhua khaub ncaws. Dilute lub detergent raws li tus neeg tsim khoom cov lus qhia.
Ntxuav:Siv txhuam txhuam los yog daim txhuam cev, txhuam txhua qhov chaw ntawm lub iav reactor thiab nws cov khoom nrog cov tshuaj ntxuav. Ua tib zoo saib xyuas cov cheeb tsam uas muaj cov tawv nqaij tawv tawv lossis cov chaw nyuaj mus cuag.
Yaug:Ua tib zoo yaug lub reactor thiab nws cov khoom nrog ntau cov dej kom tshem tawm cov khoom siv tshuaj ntxuav tes lossis tshuaj ntxuav. Rov ua cov kauj ruam no ob peb zaug kom ua tiav kev tshem tawm.
Acid Ntxuav (yog xav tau):Yog tias muaj cov pob zeb hauv av lossis cov tawv tawv uas tseem tshuav tom qab ntxuav thawj zaug, yuav tsum tau ntxuav cov kua qaub. Siv cov kua qaub diluted xws li hydrochloric acid lossis acetic acid. Ceev faj heev thaum tuav cov kua qaub thiab ua raws li cov txheej txheem kev nyab xeeb tsim nyog.
Yaug Kawg:Yaug lub reactor thiab nws cov khoom siv dua nrog dej kom tsis txhob muaj cov kua qaub ntxiv thiab xyuas kom meej tias lawv huv huv.
Kev ziab:Cia lub iav reactor thiab nws cov khoom kom cua qhuav tag ua ntej reassembly los yog cia. Tsis tas li ntawd, siv ib daim ntaub uas tsis muaj lint los yog cov ntaub so ntswg kom qhuav lawv manually.
Kev sib dhos:Thaum qhuav, rov ua cov iav reactor, saib xyuas kom ntseeg tau tias txhua qhov kev sib txuas muaj kev ruaj ntseg.
Kev lees paub:Ua ntej siv lub iav ntxuav reactor rau kev sim, ua qhov kev tshuaj ntsuam xyuas kom ntseeg tau tias nws huv huv thiab tsis muaj kab mob.
Kev tu thiab tu tsis tu ncua yog qhov tseem ceeb los ua kom lub neej ntev ntawm lub iav reactor thiab xyuas kom meej thiab txhim khu kev qha kev sim. Nco ntsoov ua raws li cov lus qhia tshwj xeeb uas tau muab los ntawm cov chaw tsim khoom ntawm lub reactor lossis ib qho khoom siv tshwj xeeb uas siv ua ke nrog nws.
Cov txheej txheem tu niaj hnub
Kev tu ib txwm ntawm 20L iav reactor yog qhov tseem ceeb los tiv thaiv kev sib kis thiab ua kom pom kev ua haujlwm zoo. Cov txheej txheem tu niaj hnub hauv qab no yuav tsum tau ua tom qab siv txhua zaus:
Disassembly:Pib los ntawm kev ua tib zoo disassembled lub reactor Cheebtsam, nrog rau cov iav raj, stirrer, condenser, thiab lwm yam accessories.
Yaug nrog Solvent:Yaug cov iav kom huv si nrog cov kuab tshuaj uas tsim nyog, xws li acetone lossis ethanol, kom tshem tawm cov tshuaj lom lossis tshuaj lom.
Scrubbing:Maj mam txhuam rau sab hauv thiab sab nrauv ntawm lub iav raj thiab lwm yam khoom siv nrog txhuam txhuam los yog daim txhuam cev kom tshem tawm cov tawv nqaij tawv.
Yaug nrog dej deionized:Yaug tag nrho cov Cheebtsam nrog dej deionized kom tshem tawm cov kuab tshuaj ntxiv thiab xyuas kom huv huv.
Kev ziab:Cia cov khoom ua kom cua qhuav kom qhuav ua ntej rov sib dhos lub reactor rau kev cia lossis siv ntxiv.
Cov txheej txheem ntxuav kom huv
Ntxiv nrog rau kev tu txhua hnub, kev tu txhua lub sijhawm ntawm 20L iav reactor yog tsim nyog los tshem tawm cov khoom seem uas tawv ncauj thiab tswj nws txoj kev ncaj ncees. Cov kauj ruam hauv qab no qhia txog cov txheej txheem tu kom huv huv uas pom zoo:
Soaking:Sau lub khob ntim nrog cov tshuaj ntxuav, xws li dilute acid los yog cov kua hauv paus, thiab cia nws so rau ob peb teev lossis ib hmos kom yaj cov khoom seem.
Scrubbing:Tom qab soaking, txhuam sab hauv ntawm lub iav hlab thiab lwm yam khoom siv nrog txhuam los yog daim txhuam cev kom tshem tawm cov seem seem zoo.
Yaug nrog dej deionized:Ua tib zoo yaug tag nrho cov khoom nrog dej deionized kom tshem tawm cov kab ntawm cov tshuaj ntxuav thiab ua kom huv huv.
Sterilization:Txhawm rau kom tsis muaj menyuam, autoclave lossis cua sov ua kom tsis muaj menyuam cov iav ntawm qhov tsim nyog kub thiab siab raws li cov txheej txheem kuaj cov txheej txheem.
Kev ziab:Thaum ntxuav thiab kom tsis muaj menyuam, tso cai rau cov khoom kom qhuav kom huv si ua ntej rov ua cov reactor siv hauv kev sim.
Kev xav txog kev nyab xeeb
Thaum ua cov txheej txheem ntxuav ntawm 20L iav reactor, nws yog ib qho tseem ceeb uas yuav tsum tau ua qhov tseem ceeb ntawm kev nyab xeeb kom tsis txhob muaj xwm txheej lossis raug tshuaj lom neeg. Yuav tsum hnav cov cuab yeej tiv thaiv tus kheej tsim nyog, suav nrog hnab looj tes, tsom iav kev nyab xeeb, thiab cov tsho hauv chav kuaj, thiab ua haujlwm nyob rau hauv qhov chaw uas muaj cua zoo kom txo tau cov pa taws lossis vapors.
Kev tuav ntawm Glassware:Kho iav iav nrog kev saib xyuas kom tsis txhob tawg lossis raug mob. Siv cov cuab yeej tsim nyog, xws li padded clamps lossis tuav, thaum sib dhos, tshem tawm, lossis txav cov iav.
Qhov cua:Xyuas kom muaj qhov cua txaus hauv chav kuaj kom tsis txhob muaj cov pa phem lossis cov pa phem. Siv cov fume hoods lossis lwm lub tshuab ua pa raws li qhov tsim nyog, tshwj xeeb tshaj yog thaum ua haujlwm nrog cov tshuaj tsis haum lossis tshuaj lom.
Cov txheej txheem xwm txheej kub ntxhov:Tsim thiab sib txuas lus meej cov txheej txheem xwm txheej ceev rau kev cuam tshuam nrog kev sib tsoo, nchuav, xau, lossis lwm yam xwm txheej cuam tshuam nrog lub iav reactor. Qhov no suav nrog cov kev khiav tawm, cov txheej txheem kaw thaum muaj xwm txheej ceev, thiab qhov chaw ntawm cov khoom siv kev nyab xeeb xws li cov tua hluav taws thiab cov chaw ntxuav qhov muag.
Chemical Handling thiab Cia:Khaws cov tshuaj kom zoo nyob rau hauv cov cheeb tsam uas raug xaiv, ua raws li cov txheej txheem kev nyab xeeb tsim nyog thiab cov ntawv sau npe. Tsis txhob khaws cov tshuaj tsis sib xws ua ke kom tsis txhob muaj qhov tshwm sim tshwm sim.
Tsis tu ncua:Ua haujlwm tsis tu ncua thiab tshuaj xyuas cov iav reactor thiab cov khoom siv sib txuas kom ntseeg tau tias kev ua haujlwm zoo thiab kev nyab xeeb. Qhov no suav nrog kev tu, lubricating qhov chaw txav, thiab hloov cov khoom hnav lossis puas.
Cov ntaub ntawv tiv tauj xwm ceev:Khaws ib daim ntawv teev cov ntaub ntawv tiv tauj thaum muaj xwm txheej ceev, suav nrog cov kev pabcuam xwm txheej kub ntxhov hauv zos, cov chaw tswj tshuaj lom, thiab cov chaw muaj feem cuam tshuam, muaj nyob hauv chav kuaj.
Xaus
Kev tu kom zoo ntawm 20L iav reactor yog qhov tseem ceeb rau kev tswj hwm nws txoj haujlwm thiab ua kom muaj kev ncaj ncees ntawm kev sim hauv kev sim.
Los ntawm kev ua raws li cov txheej txheem ntxuav tau pom zoo tau teev tseg hauv phau ntawv qhia no, cov neeg ua haujlwm hauv chaw soj nstuam tuaj yeem tshem tawm cov kab mob thiab cov khoom seem, yog li ua kom zoo dua qhov kev ua tau zoo thiab kev ntseeg siab ntawm lub reactor. Ua raws li cov txheej txheem kev nyab xeeb thiab kev saib xyuas tsis tu ncua yuav pab ua kom lub neej ntev ntawm cov cuab yeej siv thiab pab txhawb kev ua tiav ntawm kev tshawb fawb txog kev tshawb fawb.
