Dab tsi yog qhov txaus ntshai ntawm kev sib xyaw cov khoom siv cua sov sib txawv hauv ib lub raj xa dej?

# Dab tsi yog qhov teeb meem cuam tshuam nrog kev sib xyaw ntawm ntau yam khoom siv cua sov hauv ib lub raj xa dej? Txhawm rau txo cov nqi khoom, ntau cov nroj tsuag fermentation ua ke 316 stainless hlau, titanium, PFA-lined, thiab quartz cua sov Cheebtsam nyob rau hauv ib qho nruab nrab ncig voj voog. Txawm li cas los xij, lawv tsis lees paub tias kev sib cuag ntawm cov khoom sib txawv ntawm cov khoom siv hluav taws xob tsim cov galvanic, thiab cov ntaub ntawv tsis sib xws kuj ua rau cov tshuaj yaig thiab cov kav dej thaiv. Accelerated corrosion, nruab nrab contamination, thiab sudden cov khoom rupture yog ib tug ntau ntawm cov kev phom sij uas muab cov khoom sib xyaw ua ke. Cov lus hauv qab no qhia txog qhov kev pheej hmoo loj ntawm cov khoom siv sib xyaw ua ke sib xyaw ua ke.|Cov khoom sib xyaw ua ke|Core Hazard Mechanism|Pom Kev Ua Tsis Taus|Risk Level|Tswv yim Rectification Plan|| ----|-{{41}--|----|----|----|| 316 stainless hlau + liab qab carbon steel fittings|Galvanic corrosion, uas dissolves carbon steel anode|Loj xeb ntawm cov ntsiab lus tiv tauj, stainless hlau weld pitting|Siab heev|Hloov tag nrho cov khoom siv carbon steel nrog 316 stainless hlau|| Qib 2 titanium + 316 stainless hlau|Muaj peev xwm sib txawv galvanic cell, titanium zaj duab xis puas|Nruam poob hauv titanium nto tej zaum, milky discoloration|Siab|Nruab tag nrho PTFE lub tes tsho cais ntawm txhua qhov txuas txuas|| Quartz raj + hlau yeeb nkab tsis muaj gasket|Thermal expansion mismatch, mechanical stress cracking|Microcracks ntawm quartz threaded kev sib txuas, kua xau|Siab|Nruab PTFE elastic gaskets rau tag nrho cov pob qij txha quartz-hlau|| PFA lined rhaub + liab qab hlau kav|Txheej khawb abrasion, hlau ion kuab paug|Hauv zos txheej tev tawm, hlau ions kuaj pom hauv fermentation broth|Nruab nrab|Mount pem hauv ntej lim kom txo particle scouring|Qhov kev pheej hmoo loj tshaj plaws uas cuam tshuam nrog cov hlau sib xyaw ua ke yog galvanic corrosion. Lub peev xwm tshwj xeeb electrode muaj nyob rau hauv cov khoom siv fermentation nruab nrab thiab aqueous cleansing tov rau ntau yam hlau. Thaum ob cov khoom siv hlau txuas ncaj qha, cov hlau uas muaj peev xwm qis dua ua haujlwm rau kev txi anode thiab yaj sai sai, thaum cov khoom muaj peev xwm ntau dua tau ntsib cov ion yaig ntawm cov ntsiab lus sib cuag. Txawm hais tias tsis muaj fluoride nyob rau hauv nruab nrab, titanium's rhiab heev TiO₂ passivation zaj duab xis yog pheej tawm tsam thaum 316 stainless hlau thiab titanium sib koom ua ke. Tsis pub dhau peb lub hlis ntawm kev ua haujlwm sib xyaw, kev nyeem ntawv tsawg ntawm titanium yuav raug ntes los ntawm peb lub hlis twg muaj peev xwm scanning. Lwm qhov kev pheej hmoo tuag taus tshwm sim thaum quartz ua ke nrog cov kav hlau vim yog thermal expansion mismatch. Quartz muaj cov thermal expansion coefficient tsawg heev, thaum stainless hlau nthuav dav heev thaum lub sij hawm cua sov. Nyob rau hauv qhov tsis muaj elastic cais gaskets, qhov rov qab txias-kub alternation tshwm sim nyob rau hauv tsim ntawm invisible microcracks ntawm quartz vim muaj zog extrusion nro ntawm cov kev twb kev txuas threads. Thaum kawg, lub rupture ntawm lub raj thiab tag nrho poob ntawm lub tank kab lis kev cai nruab nrab tshwm sim los ntawm kev nthuav dav ntawm cov kab nrib pleb me me thaum lub sij hawm kub hloov pauv. Mechanical abrasion thiab chemical incompatibility kuj tau pom nyob rau hauv cov khoom sib xyaw ua ke. Cov txheej PFA mos yuav raug khawb los ntawm cov hlau tawv tawv hauv cov phab ntsa thaum lub sij hawm kev kub ceev nruab nrab, tshwj xeeb tshaj yog thaum cov khoom mycelium muaj nyob rau hauv cov kua zaub. Cov pa roj carbon steel substrate rusts thiab tso tawm cov hlau impurities thaum lub txheej yog scraped los ntawm, ua rau tsis ua hauj lwm ntawm GMP purity xeem cov qauv thiab cuam tshuam nrog strain loj hlob. Lub caij no, cov xeb uas tau los ntawm corroded hlau seem adheres rau qhov chaw ntawm quartz raj, uas ua rau tsim cov tawv nqaij biofilm nqa uas nyuaj rau tshem tawm los ntawm tsoos CIP tu. Qhov kev daws teeb meem tseem ceeb rau kev tshem tawm cov khoom sib xyaw ua ke txaus ntshai nyob rau hauv fermentation cua sov ncig tshuab yog los txais yuav ib qho kev sib koom ua ke tsim khoom. High-chloride biopharmaceutical kab siv tag nrho titanium loops, fermentation zaub mov dav siv ua tiav 316 stainless hlau pipelines, thiab cov txheej txheem muaj fluoride ntiav ywj siab quartz circuits uas tau cais tawm ntawm cov khoom siv hlau. Tag nrho PTFE cais cov khoom siv yuav tsum tau nruab nruab nrab ntawm txhua qhov sib txawv ntawm cov khoom sib koom ua ke los txiav tawm cov kab hluav taws xob galvanic cell loops yog tias cov khoom sib xyaw tsis tuaj yeem zam tau vim cov khoom siv uas twb muaj lawm. Elastic buffer gaskets yog yuav tsum tau rau kev sib txuas quartz-hlau. Cov pab pawg saib xyuas yuav tsum koom nrog cov khoom sib xyaw ua ke hauv kev soj ntsuam hauv lawv cov khoom soj ntsuam txhua hli, nrog rau qhov tseem ceeb ntawm qhov muaj peev xwm txawv txav, txheej txheej puas tsuaj, thiab quartz xov frosting. Qhov kev cia siab tshaj plaws thiab kev daws teeb meem ntev los tiv thaiv kev sib tshooj ntawm kev sib tsoo thiab kev ua haujlwm tsis zoo uas tsim los ntawm cov khoom siv hluav taws xob sib xyaw ua ke yog kev sib cais ntawm cov khoom sib txawv ntawm cov kav dej.
