PCB etching los ua ke kab, zoo tshuaj reactors thiab cov dej khib nyiab kho tank xav tau cov khoom siv cua sov uas muaj peev xwm ua haujlwm ruaj khov hauv kev sib xyaw corrosive media sib xyaw nrog acids, alkalis thiab organic solvents. Cov raj cua sov ua los ntawm 316 stainless hlau thiab ntshiab titanium raug kev kub ntxhov ceev hauv kev hloov cov kua qaub thiab alkaline cuam tshuam, whereas quartz cua sov raj yog raug rau irreversible corrosion ib zaug raug rau alkaline kua. Raws li qib siab- kawg tiv thaiv- cov khoom cua kub corrosion, PFA cov cua sov tiv thaiv tau txais ib qho -daim seamless molded perfluoroalkoxy resin ua txheej thaiv txheej, cais cov cua sov sab hauv los ntawm cov kua dej corrosive. Ntau ntawm -cov neeg ua haujlwm hauv chaw haujlwm tau sib cav seb PFA cov khoom siv cua sov puas tuaj yeem hloov cov raj hlau cua sov tag nrho. Daim ntawv no piav qhia nws cov txiaj ntsig tshwj xeeb, pom tseeb qhov tsis zoo thiab cov kev txwv uas siv tau, nrog rau cov lus sib piv ntawm cov kev ua haujlwm tseem ceeb rau plaub lub ntsiab tiv thaiv - cov khoom siv cua sov.
Qhov tseem ceeb tshaj plaws ntawm cov khoom siv PFA yog nws qhov dav - ntau yam tshuaj inertness. Stable fluorocarbon molecular chains NW nyuam qhuav hnov nrog feem ntau inorganic acids, alkalis, tshuaj chloride thiab feem ntau siv industrial organic solvents. Titanium cua sov raj nyob ntawm tus kheej-regenerative oxide passivation films rau kev tiv thaiv- kev ua haujlwm corrosion, tab sis kub concentrated alkali yuav ua rau puas tsuaj xws li kev tiv thaiv kev tiv thaiv. 316 stainless hlau tsuas yog haum me ntsis corrosive ib puag ncig thiab yooj yim tsim pitting corrosion nyob rau hauv alternating acid-baseeros Sib txawv ntawm cov ntaub ntawv hlau tiv thaiv los ntawm cov yeeb yaj kiab tsis zoo, PFA paub txog kev tiv thaiv - muaj peev xwm corrosion los ntawm kev sib cais ntawm lub cev. Nws cov txheej txheej du tiv thaiv cov av thiab nplai tsub zuj zuj thiab txo qhov tshwm sim tshwm sim ntawm qhov chaw xeb. Tsis tas li ntawd, PFA boasts zoo heev insulating kev ua tau zoo, zoo txo cov hluav taws xob xau zais kev phom sij hauv kev cob qhia tshuaj lom neeg.
Cov lus hauv qab no sib piv cov ntsiab lus tseem ceeb ntawm plaub los tiv thaiv -cov khoom siv cua sov:
表格
| Cua sov ntaus ntawv hom | Acid{0}}Alkali Adaptability | Max Ntev -Lub Sijhawm Ua Haujlwm Kub | Impact & Scratch Resistance | Medium Contamination Risk | Tus nqi yuav khoom |
|---|---|---|---|---|---|
| PFA Jacketed rhaub | Zoo heev, muaj feem xyuam rau kev sib xyaw acid thiab alkali nruab nrab | 250 degree | Tsis zoo, txheej yooj yim rau khawb | Zero pollution ua ntej txheej tawg | Nruab nrab-High |
| 316 Stainless hlau rhaub | Inferior, susceptible rau pitting corrosion | 560 degree | Cov qauv tsim muaj zog heev | Taug qab hlau ion nag lossis daus | Tsawg |
| Ntshiab Titanium rhaub | Cov kua qaub zoo heev, ua haujlwm tsis zoo hauv cov kua kub alkaline | 780 degree | Muaj zog mechanical toughness | Me hlau ion nag lossis daus | Siab |
| Quartz cua sov Tube | Tsuas yog cov kua qaub- tiv taus, hnyav heev los ntawm alkali | 1180 degree | Tsis muaj zog heev | Tsis muaj kab mob kis tau | Nruab nrab |
Hauv nruab nrab -tsis kub ntau- cov khoom siv corrosive piv txwv los ntawm PCB etching tso tsheb hlau luam, PFA cov raj tiv thaiv cua sov ua kom pom qhov sib tw tsis zoo. Cov kav hlau cua sov yuav tsum tau hloov tas li thiab ua rau muaj kev cuam tshuam ntau dua. PFA cov cua sov tuaj yeem txhawb nqa kev ua haujlwm tsis tu ncua rau kwv yees li ob xyoos nrog qhov tsis ua haujlwm tsawg. Lawv yuav tsis precipitate hlau ions kom paug cov tshuaj etching, tswj cov khoom zoo ib yam thiab zoo hauv kev ua hluav taws xob. Txawm li cas los xij, qhov tsis xws luag hauv qhov tsis tuaj yeem raug saib xyuas. Qhov ntev -lub sij hawm kub txwv ntawm 250℃txiav txim tawm tag nrho cov txheej txheem kub ntau lawm -. Lub fluoroplastic txheej casing muaj kev hnav tsis zoo; ib zaug khawb los yog pierced, corrosive kua yuav ncaj qha mus cuag lub puab hlau core thiab ua rau kom ceev cov khoom burnout. Cov txheej txheem wrapping thiab molding nyuaj kuj tseem txhawb nqa tag nrho cov nqi tsim khoom.
Nyob rau hauv cov ntsiab lus, PFA tiv thaiv cua sov raj tsis tuaj yeem ua raws li kev hloov pauv thoob ntiaj teb rau tag nrho cov hlau cua sov raj. Rau siab -cov txheej txheem kub lossis qhov chaw ua haujlwm nrog kev sib txhuam thiab kev sib tsoo, cov titanium lossis stainless hlau cua sov raj tseem muaj ntau qhov kev xaiv. PFA tiv thaiv cua sov yuav tsum tau teev raws li qhov tseem ceeb tshaj plaws tsuas yog thaum ua haujlwm kub qis dua 250℃thiab qhov nruab nrab muaj cov kua qaub thiab alkali sib xyaw. Cov kws ua haujlwm cog qoob loo yuav tsum xaiv cov khoom cua sov raws li qhov nruab nrab muaj pes tsawg leeg, cov qauv ntsuas kub, ntawm -qhov chaw kho tshuab thiab kev yuav nyiaj txiag, txhawm rau ua kom tau txais txiaj ntsig zoo ntawm cov khoom siv txhim khu kev qha thiab kev ua haujlwm ntev - kev lag luam.
