Seawater circulating heating systems for offshore equipment, electroplating pickling tanks, brackish water treatment and high -salinity chemical reaction kettles are subject to the heavy erosion from chloride ions and weak acidic substances. Ordinary 316 stainless hlau cua sov raj tau yooj yim tsim pitting corrosion thiab puas passive films nyob rau hauv ntev -lub sij hawm siab chloride concentration, ua rau nruab nrab to thiab cov khoom nres. PFA qhwv cov cua sov yog txwv los ntawm qhov kub siab tshaj plaws, thaum quartz raj tsis tuaj yeem tiv taus chloride corrosion thiab mechanical shock. Nrog rau cov tshuaj chloride corrosion zoo heev, ruaj khov siab -kub tsis kam thiab hnav zoo nkauj, ntshiab titanium cua sov tubs ua haujlwm siab - kawg tiv thaiv -corrosion cua sov consumables rau hnyav corrosive ib puag ncig. Daim ntawv no piav qhia nws cov yam ntxwv ntawm cov khoom siv tseem ceeb, txwv tsis pub siv cov kev txwv thiab cov txheej txheem xaiv engineering, suav nrog cov lus sib piv ntawm kab rov tav ntawm plaub cov khoom siv cua sov.
1. Core Performance Advantages ntawm Ntshiab Titanium
titanium tuaj yeem ua kom muaj zog thiab ruaj khov titanium oxide passive zaj duab xis nyob rau hauv ib puag ncig aqueous, uas boasts deb superior tiv thaiv chloride - ua rau pitting corrosion, crevice corrosion thiab seawater yaig piv nrog 316 stainless hlau. Txawm hais tias muaj kev khawb me me tshwm sim thaum lub sijhawm ua haujlwm, cov zaj duab xis passive tuaj yeem kho nws tus kheej sai sai hauv brine, seawater thiab electrolytic pickling daws.
Nyob rau hauv cov nqe lus ntawm lub cev thiab txhua yam khoom, ntshiab titanium nta tsim nyog tensile lub zog, zoo heev thermal qaug zog tsis kam thiab tsawg ntom. Nws tuaj yeem tiv taus cua sov thiab cua txias ntau zaus yam tsis muaj cov yeeb nkab deformation lossis foob tawg, thiab tuaj yeem khoov thiab kho rau hauv cov duab tshwj xeeb kom haum rau cov txheej txheem nyuaj. Nws qhov siab tshaj plaws kev ruaj ntseg ua hauj lwm kub nyob rau hauv qhuav ib puag ncig ncav cuag 770 degree, txaus siab rau feem ntau nruab nrab - mus rau - kub kub industrial cua sov yuav tsum. Tsis tas li ntawd, titanium tsis tshua yaj cov hlau ions mus rau hauv nruab nrab, ua kom cov kua purity tau zoo rau ib qib twg.

表格
| Cua sov Cheebtsam Hom | Chloride Corrosion Resistance | Max Nruam Ua Haujlwm Temp | Acid{0}}Alkali Adaptability | Mechanical Toughness | Tag Nrho -Tus Nqi Ua Haujlwm Lub Neej |
|---|---|---|---|---|---|
| Ntshiab Titanium Heating Tube | Zoo heev, ruaj khov nyob rau hauv siab -concentration chloride nruab nrab | 770 degree | Zoo rau qaug zog acid & nruab nrab kua, tsis nyob rau hauv kub concentrated muaj zog alkali | High toughness, tiv thaiv - vibration thiab khoov tau | Tus nqi pib siab, lub neej ua haujlwm ntev heev hauv dej hiav txwv thiab brine |
| 316 Stainless hlau | General, susceptible to pitting nyob rau hauv siab chloride theem | 550 degree | Tsuas yog haum rau me ntsis corrosive tej yam kev mob | High rigidity thiab abrasion kuj | Kev nqis peev qis dua, kev pabcuam luv luv hauv dej ntsev |
| Quartz cua sov Tube | Tsis zoo, tsis muaj peev xwm tiv taus chloride nruab nrab corrosion | 1180 degree | Tsuas yog inert rau ib qho muaj zog acid | Heev nkig, tawg yooj yim thaum sib tsoo | Cov nqi hloov pauv siab tom qab kev tawg, tsuas yog rau kev kuaj mob zoo li qub |
| PFA Encapsulated rhaub | Txaus siab rau cov tshuaj chloride- uas muaj qhov nruab nrab | 250 degree | Zoo meej rau cov kua qaub-alkali hloov pauv | Cov txheej mos mos, yooj yim rau kev tho los ntawm cov khoom tawv tawv | Tus nqi nruab nrab, nruj me ntsis qis dua 250 degree |
3. Inherent Defects thiab nruj siv txwv ntawm Titanium Tubes
Ua ntej, cov titanium ntshiab yuav raug mob hnyav heev thaum soaked nyob rau hauv kub concentrated muaj zog alkaline tov xws li siab -kub sodium hydroxide tov, li no nws yog txwv tsis pub rau kev ua hauj lwm tej yam kev mob nrog rau ntev - immersion nyob rau hauv siab - kub muaj zog alkali. Qhov thib ob, hydrofluoric acid thiab fluoride- muaj cov xov xwm yuav ncaj qha rhuav tshem nws cov yeeb yaj kiab tiv thaiv thiab ua rau muaj kev xeb sai sai.
Tsis tas li ntawd, cov khoom siv raw thiab cov nqi ua haujlwm ntawm cov titanium ntshiab yog ntau dua li cov hlau tsis muaj steel, ua rau hnyav ib qho - sij hawm peev. Xaiv cov titanium raj rau qis -chloride thiab me me-corrosion cov pa dej sib xyaw ua rau kev ua tau zoo tshaj plaws thiab kev lag luam tsis zoo. Tsis tas li ntawd, titanium nyiam oxidize, hlawv thiab lo thaum lub sij hawm siab - vuam vuam, uas xav tau cov txheej txheem vuam thiab kev tswj cov txheej txheem nruj.
4. Cov lus qhia txog kev xaiv qhov xaus thiab engineering
Ntshiab titanium cua sov raj yog qhov kev nyiam tshaj plaws los tiv thaiv - corrosion cua sov tov rau seawater ncig, siab - salinity khib nyiab, electroplating pickling kua thiab lwm yam siab -chloride hnyav ua hauj lwm scenarios. Hauv kev sib piv cov khoom siv engineering, titanium raj yuav tsum tau ua ntej rau cov khoom siv hauv hiav txwv, cua sov dej thiab ntev -lub sij hawm brine cua sov loops. Rau cov kub muaj zog alkali thiab fluorine- muaj cov xov xwm corrosive, PFA encapsulated cua sov cov ntsiab lus yuav tsum tau saws los hloov. Rau cov pa qis -corrosion circulating dej systems, 316 stainless hlau xa cov nqi zoo dua-kev ua tau zoo. Tsuas yog los ntawm kev sib piv nruab nrab muaj pes tsawg leeg, kev khiav hauj lwm kub thiab corrosion hnyav nrog cov khoom siv hauv lub cev tuaj yeem ua tiav qhov sib npaug ntawm kev ua haujlwm kub ruaj khov thiab kev siv nyiaj tag nrho.
