Vim tias cov peev txheej dej qab zib thoob ntiaj teb nyob rau hauv kev nyuaj siab zuj zus, kev lim dej hiav txwv tau tshwm sim los ua qhov kev daws teeb meem tseem ceeb rau kev ruaj ntseg cov khoom siv dej kom ruaj khov, tshwj xeeb tshaj yog nyob rau hauv cov cheeb tsam ntug dej hiav txwv thiab cov cheeb tsam qhuav. Hauv cov txheej txheem lim dej ntsev, cov hlau tsis xeb ua lub luag haujlwm tseem ceeb vim nws qhov kev tiv thaiv corrosion zoo, lub zog kho tshuab, thiab lub neej ntev.
Vim li cas cov hlau tsis xeb thiaj zoo tagnrho rau kev lim dej hiav txwv?
1. Kev Tiv Thaiv Chloride Zoo Tshaj Plaws
Dej hiav txwv muaj cov chloride ions (Cl⁻) ntau heev, uas tuaj yeem ua rau cov hlau ib txwm xeb. Cov hlau tsis xeb Austenitic xws li 316L, thiab cov qib duplex xws li S32205 thiab S32750, muaj kev tiv thaiv zoo heev rau kev xeb pitting thiab crevice hauv cov chaw saline.
2. Lub Neej Ua Haujlwm Ntev, Txo Kev Txij Nkawm
Cov khoom siv ua los ntawm cov hlau tsis xeb tuaj yeem ua haujlwm tau zoo hauv qhov chaw nyuaj, muaj ntsev ntau, thiab muaj av noo ntau. Qhov kev ruaj khov no txo qhov kev siv tsis ua haujlwm thiab cov nqi kho, ua kom muaj kev ua haujlwm zoo mus ntev.
3. Kev Ua Tau Zoo thiab Lub Zog
Cov hlau tsis xeb muaj qhov sib xyaw ua ke zoo ntawm lub zog thiab kev ywj pheej, ua rau lawv tsim nyog rau kev vuam, kev tsim, thiab kev siv tshuab. Lawv siv dav hauv cov khoom tseem ceeb ntawm kev lim dej xws li cov kav dej, cov hlab siab, cov khoom hloov pauv cua sov, thiab cov evaporators.
Cov Qib Hlau Stainless Feem Ntau Siv Hauv Kev Desalination
| Qib | Hom | Cov Nta Tseem Ceeb | Cov Ntawv Thov Ib Txwm Muaj |
| 316L | Austenitic | Kev tiv thaiv corrosion zoo, weldable | Cov kav dej, cov li qub, cov thav duab |
| S32205 | Ob chav | Muaj zog heev, tiv taus pitting zoo heev | Cov hlab ntsha siab, cov khoom hloov pauv cua sov |
| S32750 | Super Duplex | Kev tiv thaiv zoo heev rau kev tawm tsam chloride | Cov kav dej tob hauv hiav txwv, cov plhaub evaporator |
| 904L | High-Alloy Austenitic | Tiv taus cov kua qaub thiab cov dej ntsev | Cov plhaub twj tso kua mis, cov khoom sib txuas |
Cov Ntawv Thov Tseem Ceeb hauv Cov Tshuab Desalination
• Cov Chav Reverse Osmosis (RO):Cov khoom xws li cov lim dej thiab cov hlab ntsha membrane feem ntau yog ua los ntawm 316L lossis S32205 stainless hlau kom tiv taus kev kub siab thiab kev raug dej ntsev.
• Kev Siv Dej Hiav Txwv Los Ntawm Thermal (MSF/MED):Cov txheej txheem no xav tau cov ntaub ntawv uas muaj qhov kub thiab txias thiab tiv taus xeb. S32750 super duplex stainless hlau feem ntau yog siv.
• Cov Txheej Txheem Nqus Dej Thiab Cov Dej Ntshav Tawm:Cov khoom uas yooj yim xeb tshaj plaws ntawm lub kaw lus, xav tau cov khoom siv ruaj khov kom tiv thaiv kev xau thiab xyuas kom ruaj khov mus sij hawm ntev.
