Intermittent batch synthesis reactors rau cov tshuaj tshwj xeeb zoo, txuas ntxiv PCB cov txheej txheem ntub dej etching thiab cov dej khib nyiab pH txias cov dej khib nyiab tau ntsib nrog cyclic corrosion nres los ntawm acidic thiab alkaline dosing media, nrog rau cov khoom siv o thiab kev laus puas tsuaj los ntawm ntev -lub sij hawm soaking hauv ketones, organic solvent thiab esters. Cov khoom siv hluav taws xob ua cua sov ua los ntawm 316 stainless hlau thiab cov khoom lag luam ntshiab titanium cia siab rau hauv -situ tsim oxide passive films los tiv thaiv - tiv thaiv corrosion. Cov kev hloov pauv pH tsis tu ncua yuav ua rau tsis tu ncua ua rau cov txheej txheem tiv thaiv tsis tu ncua, uas ua rau muaj qhov cuam tshuam pitting corrosion, dhau los ntawm - phab ntsa nkag mus thiab so ntxov ntxov ntawm cov cua sov sib dhos. Thaum fused quartz cua sov raj khav theeb tshwj xeeb acid tsis kam, lawv yuav dhau los ua cov tshuaj lom neeg tsis zoo thiab tawg tawg ib zaug raug rau alkaline aqueous daws. Ua raws li lub cev thaiv kev sib cais tsim lub tswv yim, seamless integral PFA kub-melt lined immersion cua sov cov ntsiab lus cais tawm hauv cov hlau cua sov cov tub ntxhais los ntawm tag nrho cov kua dej corrosive, qhia tau hais tias muaj zog adaptability rau complex multi-factor corrosive industrial production environment. Daim ntawv no piav qhia txog nws qhov txawv ntawm cov khoom siv zog, lub hom phiaj kev txwv kev txwv thiab cov qauv kev xaiv engineering, nrog rau cov lus qhia tshiab uas tau npaj ntau qhov sib piv cov lus uas npog plaub cov khoom siv hluav taws xob loj.
1. Cov txiaj ntsig tseem ceeb thiab Kev Tiv Thaiv -Corrosion Mechanism of Integrated Hot- Melt PFA Lining
Qhov tseem ceeb ntawm kev sib tw ntawm PFA fluoropolymer nyob rau hauv nws ze li ntawm cov tshuaj tsis muaj zog, uas qhov tseem ceeb sib txawv ntawm cov hlau cua sov cov raj uas nws cov corrosion kuj yog txwv los ntawm nruab nrab pH nqi thiab redox peev xwm. Qhov ntom ntom, tsis yog- ntxeem tau ib qho- daim fluoroplastic hauv ob sab phlu yuav tsis yaj, o los yog pib cov tshuaj tiv thaiv thaum raug rau feem ntau inorganic muaj zog acids, muaj zog alkalis, halide brines thiab feem ntau siv industrial organic solvents. Qhov tseem ceeb kub-melt seamless molding thev naus laus zis ua kom nruj cov kab permeation ntawm micro corrosive molecules, zoo kawg nkaus haum rau cov khoom siv tsis tu ncua uas yuav tsum tau noj ntau zaus, hloov khoom siv thiab reactor sab hauv tu.
Sib nrug los ntawm kev ruaj khov los tiv thaiv- kev ua haujlwm corrosion, ultra- du tsis yog - lo rau sab hauv thiab sab nrauv sab hauv kom txo tau qhov adhesion ntawm limescale, polymer flocculent precipitates thiab nplaum nplaum residues, ua tau zoo kom tsis txhob maj mam poob ntawm kev sib pauv cua sov ua kom muaj zog 3}} lub sij hawm ntev. Lub caij no, cov khoom siv PFA muaj cov khoom siv hluav taws xob zoo tshaj plaws, tshem tawm cov hluav taws xob hluav taws xob uas muaj peev xwm ua rau muaj kev phom sij hauv siab -cov av noo corrosive chemical workshops thiab nqa tag nrho cov kev nyab xeeb ntawm cov hluav taws xob ua kom sov.
