Cov kav dej ua haujlwm nyob rau hauv qhov chaw siab - qhov kub thiab txias, xws li thauj cov roj kub, roj, lossis chav dej, ntsib cov teeb meem tshwj xeeb. Kev sib xyaw ua ke ntawm qhov kub thiab txias thiab cov ntsiab lus corrosive tuaj yeem ua kom cov khoom siv degradation, ua rau cov txheej txheem ntxov ntxov, nce nqi kho, thiab muaj peev xwm muaj kev nyab xeeb. Txawm hais tias muaj ntau yam kev tiv thaiv- txheej txheej corrosion, Fusion Bonded Epoxy (FBE) txheej tau ua pov thawj tsis tu ncua los ua cov kev daws teeb meem rau cov kev xav tau no. Tab sis yog vim li cas FBE txheej txheej yog qhov kev daws teeb meem zoo tshaj plaws rau siab - qhov kub thiab txias ib puag ncig, thiab cov khoom dab tsi ua rau nws muaj txiaj ntsig zoo? Hebei Huayang Steel Pipe Co., Ltd., tus thawj coj ntawm kev tiv thaiv -corrosion yeeb nkab kev daws teeb meem, piav qhia txog kev zoo ntawm FBE txheej hauv siab - daim ntawv thov kub.
Qhov Kev Nyuaj Siab Dual: Kub Kub thiab Corrosion
Kub kub exacerbate corrosion nyob rau hauv ntau txoj kev:
• Cov tshuaj tiv thaiv kab mob nrawm: Cov tshuaj tiv thaiv tshuaj, suav nrog kev xeb, feem ntau ua sai dua ntawm qhov kub siab dua. Qhov no txhais tau hais tias cov tshuaj corrosive tuaj yeem tua cov yeeb nkab saum npoo ntau dua.
•Coating Degradation: Ntau cov pa coatings tuaj yeem muag, tawg, lossis tawg ntawm qhov kub siab, poob lawv cov khoom tiv thaiv.
•Cathodic Disbondment: Cov txiaj ntsig ntawm kev tiv thaiv cathodic (CP) tuaj yeem cuam tshuam rau qhov kub thiab txias, thiab cov txheej txheem nrog cov adhesion tsis zoo tuaj yeem cuam tshuam ntau dua hauv CP cov xwm txheej.
• Thermal Cycling: Cov kub hloov pauv tuaj yeem ua rau muaj kev ntxhov siab hauv cov txheej txheej, ua rau tawg lossis delamination dhau sijhawm.
Cov yam tseem ceeb no yuav tsum muaj cov txheej txheem txheej txheej uas muaj peev xwm tswj tau nws txoj kev ncaj ncees thiab kev tiv thaiv zoo txawm tias raug kub hnyiab.
Cov Khoom Tshwj Xeeb ntawm FBE Txheej
FBE yog cov thermosetting polymer txheej siv los ua cov hmoov qhuav rau cov yeeb nkab steel preheated. Thaum sib cuag nrog cov yeeb nkab kub saum npoo, cov hmoov melts, ntws, thiab kho kom tsim tau ib zaj duab xis tsis tu ncua. Nws cov qauv molecular thiab daim ntawv thov txheej txheem muab nws qhov zoo sib xws rau kev ua haujlwm siab - kub:
1. Zoo heev Adhesion ntawm siab kub
FBE tsim cov tshuaj muaj zog (covalent) daim ntawv cog lus nrog cov hlau substrate. Cov ntawv cog lus no ruaj khov heev thiab tuav nws txoj kev ncaj ncees txawm tias qhov kub siab ua haujlwm siab. Superior adhesion yog qhov tseem ceeb vim nws:
• Tiv thaiv kev tsis sib haum xeeb: Tiv thaiv qhov nyiam ntawm cov txheej txheem kom cais tawm ntawm cov yeeb nkab, uas tuaj yeem tsim txoj hauv kev rau corrosion.
• Txhim khu kev tiv thaiv Cathodic: Ib qhov dej zoo-adhered FBE txheej ua haujlwm sib koom ua ke nrog cathodic tiv thaiv kab ke, tiv thaiv cathodic disbondment thiab ua kom ntev - lub sij hawm corrosion.
2. High iav Hloov Kub Kub (Tg)
FBE coatings yog tus cwj pwm los ntawm qhov kub hloov pauv iav (Tg). Tg yog qhov kub ntawm qhov amorphous polymer hloov los ntawm ib qho nyuaj, glassy xeev mus rau softer, rubbery xeev. Lub siab Tg txhais tau hais tias FBE tuav nws cov hardness, mechanical zog, thiab barrier zog ntawm qhov kub thiab txias qhov twg ntau lwm coatings yuav soften, deform, los yog ntws. Qhov no tso cai rau FBE tiv thaiv:
•Operating Temperature: Sustained raug rau cov dej kub yam tsis poob nws txoj kev tiv thaiv.
•Soil Stress: Resistant deformation thiab puas los ntawm av txav, txawm tias thaum kub.
3. Superior Hardness thiab Abrasion Resistance
FBE coatings yog inherently nyuaj thiab tawv, muab kev tiv thaiv zoo heev rau abrasion thiab cuam tshuam. Qhov no yog qhov tseem ceeb thaum lub sij hawm tuav cov yeeb nkab, kev thauj mus los, kev teeb tsa, thiab rov qab ua haujlwm, qhov twg cov khoom puas tuaj yeem nthuav tawm cov hlau. Qhov hardness no khaws cia txawm nyob rau ntawm qhov kub siab dua, muab kev tiv thaiv txuas ntxiv tiv thaiv sab nraud.
4. Cov tshuaj tiv thaiv zoo
FBE muab kev tiv thaiv zoo tiv thaiv ntau yam tshuaj corrosive, nrog rau cov kua qaub, alkalis, thiab ntsev feem ntau pom hauv av thiab cov kua dej thauj. Cov tshuaj inertness no yog khaws cia ntawm qhov kub thiab txias, ua kom cov txheej txheem tseem ua haujlwm zoo nyob rau hauv ib puag ncig hnyav.
5. High Dielectric zog
FBE coatings muaj lub zog dielectric siab, txhais tau tias lawv yog cov hluav taws xob zoo heev. Cov cuab yeej no yog qhov tseem ceeb rau kev tiv thaiv kev cuam tshuam tam sim no thiab ua kom muaj kev ua haujlwm zoo ntawm cathodic tiv thaiv kab ke, uas tso siab rau kev sib cais hluav taws xob ntawm cov yeeb nkab los ntawm nws ib puag ncig.
6. Ib qho - Txheej Simplicity thiab Kho
Thaum feem ntau siv los ua cov primer hauv ntau- txheej txheej txheej (xws li 3LPE), FBE kuj tuaj yeem siv ua ib leeg ib leeg- txheej txheej. Nws cov zaj duab xis nyias nyias (feem ntau yog 300-500 microns) tso cai rau kev tshuaj xyuas thiab kho tau yooj yim hauv daim teb, txo qis sijhawm thiab nqi.
Daim ntawv thov ntawm FBE Txheej nyob rau hauv siab -Tub kub ib puag ncig
FBE txheej yog dav siv nyob rau hauv ntau yam siab -kub pipeline applications, suav nrog:
• Cov Roj Kub Kub thiab Cov Hluav Taws Xob Hluav Taws Xob: thauj cov roj av, cov khoom ua kom zoo, thiab cov pa roj ntsha ntawm qhov kub siab.
•Geothermal Pipelines: Siv nyob rau hauv geothermal zog tej yaam num uas kav kav dej kub los yog chav.
•District Heating Systems: Rau cov kav dej faib dej kub lossis chav rau cua sov.
• Txheej Txheem Piping: Hauv cov nroj tsuag uas muaj cov txheej txheem cov kua dej yog khaws cia ntawm qhov kub thiab txias.
