Intermittent tshuaj tiv thaiv kettles rau cov tshuaj zoo tsim, nruam PCB etching ntau lawm kab thiab muaj dej khib nyiab pH neutralization pas dej ua ke yog raug mus rau ntev -lub sij hawm alternating corrosion los ntawm acidic thiab alkaline txheej txheem kua, raws li zoo raws li immersion corrosion los ntawm ketones, esters thiab lwm yam organic solvents. Cov khoom siv hluav taws xob cua sov cov raj uas sawv cev los ntawm 316 stainless hlau thiab ntshiab titanium tso siab rau cov yeeb yaj kiab uas tau tsim los rau kev tiv thaiv - tiv thaiv corrosion. Kev hloov pauv pH ntau zaus yuav ua rau cov yeeb yaj kiab tiv thaiv tsis tu ncua tsis tu ncua ntawm tus kheej - kho, thaum kawg ua rau pitting corrosion, los ntawm - phab ntsa perforation thiab ntxov ntxov ntawm cov kav dej cua sov. Quartz cua sov raj muaj cov kua qaub zoo heev tab sis yuav raug kev txom nyem irreversible chemical corrosion thiab nkig tawg ib zaug raug rau alkaline daws. Raws li lub hauv paus ntsiab lus ntawm kev sib cais ntawm lub cev, ib qho -daim seamless PFA coated cua sov tubes cais cov hlau hauv cov cua kub ntawm tag nrho cov corrosive media, uas qhia tau hais tias muaj zog adaptability rau complex thiab sib txawv corrosive kev lag luam ib puag ncig. Daim ntawv no piav qhia nws cov txiaj ntsig zoo ntawm cov khoom siv tseem ceeb, kev txwv tsis pub siv thiab cov qauv kev xaiv engineering, nrog rau ntau ntau- Performance index piv cov lus sib piv ntawm plaub cov khoom siv cua sov uas txuas nrog.
1. Cov txiaj ntsig tseem ceeb thiab Kev Tiv Thaiv -Corrosion Principple of Integrated PFA Txheej
Qhov tseem ceeb ntawm kev sib tw zoo ntawm PFA cov khoom nyob rau hauv nws tag nrho - ntau yam tshuaj inertness, uas yog qhov tseem ceeb sib txawv ntawm cov hlau cua sov raj uas nws corrosion kuj yog txwv los ntawm nruab nrab pH nqi thiab redox ib puag ncig. The dense and pore-free integrated fluoroplastic outer coating will not dissolve, swell or participate in chemical reactions when contacting most inorganic strong acids, strong alkalis, halide solutions and commonly used industrial organic solvents. Cov qauv tsim seamless sib xyaw ua kom zoo thaiv cov kev nkag mus ntawm cov me me corrosive molecules, zoo kawg nkaus yoog mus rau qhov sib txawv batch ntau lawm hom ntawm nquag pub noj thiab hloov ua kua.
Ntxiv rau qhov ruaj khov los tiv thaiv-kev ua haujlwm corrosion, ultra- du tsis yog- nplaum sab nrauv zoo heev txo cov adhesion ntawm nplai, polymer precipitates thiab viscous residues, zoo zam qhov maj mam poob ntawm tshav kub hloov efficiency tshwm sim los ntawm ntev - lub sij hawm av txuam. Nyob rau tib lub sijhawm, PFA muaj kev ua haujlwm zoo ntawm rwb thaiv tsev, tshem tawm qhov kev pheej hmoo ntawm hluav taws xob to hauv cov chaw ua haujlwm chemical thiab corrosive thiab txhim kho tag nrho cov kev nyab xeeb ntawm cov khoom siv hluav taws xob ua tiav.

3. Qhov tsis xws luag thiab qhov yuav tsum tau ua daim ntawv thov txwv ntawm PFA cua sov Tubes
Ob qhov kev tsis txaus ntseeg tau txwv qhov loj - nplai nce qib ntawm ib qho -daim seamless PFA coated cua sov raj. Ua ntej, qhov kev txwv sab saud ntawm qhov ntev - lub sij hawm tsis tu ncua kev nyab xeeb kev khiav hauj lwm kub yog tsau ntawm 250℃, uas tsis tuaj yeem ua tau raws li cov txheej txheem ntawm high -kub acid hydrolysis, thermal reflux decomposition thiab siab -kub polymerization synthesis. Qhov thib ob, fluoroplastic txheej txheej yog tsawg- cov khoom siv polymer hardness; ib zaug khawb los yog pierced los ntawm nplawm paddles, khoom impurities thiab ntse txawv teb chaws cov khoom, lub puab hlau puag yeeb nkab yuav ncaj qha corroded thiab ua rau cia li kaw cov khoom tsis ua hauj lwm. Tsis tas li ntawd, qhov ua tau zoo ntawm ib qho - cov txheej txheem seamless txheej molding ua rau tus nqi siab dua li cov kav hlau tsis zoo li qub.
Cov lus ceeb toom tseem ceeb: PFA txheej tsis tuaj yeem tiv taus siab -kub molten alkali hlau thiab siab -concentration fluorine- muaj cov xov xwm, uas yuav tsum tsis suav nrog hauv kev ntsuas kev ua haujlwm thaum ntxov thiab cov txheej txheem tsim theem.
4. Xaus thiab Ntawm -Tsev Kawm Ntawv Kev Xaiv Cov Kev Qhia
Ib qho -daim seamless PFA coated cua sov raj yog lub hom phiaj tshaj plaws thiab txhim khu kev qha cov khoom siv cua sov rau nruab nrab- qhov kub thiab txias ua haujlwm nrog cov kua qaub sib xyaw ua ke - puag alternating corrosion thiab organic hnyav cuam tshuam. Hauv kev muab khoom siv tiag tiag thiab kev sib koom ua haujlwm engineering, cov txheej txheem engineers yuav tsum ua qhov tseem ceeb ntawm cov khoom no rau pH- hloov pauv batch reactors, PCB etching tanks thiab cov dej khib nyiab neutralization tanks. Rau siab -cov txheej txheem kub, feem ntau mechanically hnyav ua hauj lwm tej yam kev mob thiab ntev -lub sij hawm ib alkaline immersion ib puag ncig, titanium cua sov raj los yog enamel cua sov ntsiab yuav siv tau raws li lwm txoj kev. Tsuas yog los ntawm kev sib piv cov ntaub ntawv kev ua tau zoo nrog rau qhov tseeb ntawm - qhov chaw ua haujlwm tuaj yeem ua kom pom qhov sib npaug ntawm qhov ntev - lub sijhawm ua haujlwm ruaj khov ntawm cov cuab yeej siv thiab tag nrho cov phiaj xwm peev yuav raug lees paub.
