Kev tiv thaiv cov kav hlau los ntawm kev xeb yog qhov tseem ceeb ntawm kev ua kom lawv lub neej ntev, kev nyab xeeb, thiab kev ua haujlwm zoo. Ntawm cov feem ntau siv thiab siv tau zoo sab nraud los tiv thaiv-corrosion txheej txheej yog 3LPE (Peb- Txheej Polyethylene) txheej thiab FBE (Fusion Bonded Epoxy) txheej. Ob leeg muaj kev tiv thaiv zoo, tab sis lawv txawv qhov sib txawv hauv lawv qhov muaj pes tsawg leeg, daim ntawv thov, thiab kev siv zoo. Kev nkag siab txog cov kev sib txawv no yog qhov tseem ceeb rau kev xaiv cov txheej txheem tsim nyog rau cov haujlwm tshwj xeeb. Yog li, dab tsi yog qhov txawv ntawm 3LPE thiab FBE txheej rau steel yeeb nkab tiv thaiv, thiab thaum twg yuav tsum tau nyiam? Hebei Huayang Steel Pipe Co., Ltd., uas yog ib qho chaw muab kev pabcuam kev tiv thaiv kev tiv thaiv corrosion, qhia meej txog qhov sib txawv tseem ceeb no.
Txheej txheem cej luam ntawm 3LPE thiab FBE Txheej
Ua ntej dhia mus rau hauv qhov sib txawv, cia peb luv luv recap txhua txheej:
•FBE (Fusion Bonded Epoxy) Txheej: Ib txheej -, thermosetting epoxy hmoov txheej siv rau cov yeeb nkab steel preheated. Nws yaj, ntws, thiab kho kom tsim tau ib zaj duab xis tas mus li uas chemically bonds rau steel nto. FBE paub txog nws txoj kev adhesion zoo, siab corrosion kuj, thiab zoo tshuaj tiv thaiv.
•3LPE (Peb-Txheej Polyethylene) Txheej: Ib txheej txheej ntau- txheej txheej muaj peb txheej sib txawv: ib txheej FBE sab hauv, txheej nruab nrab copolymer nplaum txheej, thiab txheej txheej polyethylene (PE) txheej. Cov txheej txheem no sib xyaw ua ke zoo tshaj plaws adhesion thiab tiv thaiv corrosion ntawm FBE nrog cov khoom siv tiv thaiv zoo ntawm PE.

1. Txheej Txheem thiab Txheej Txheem
•FBE: Raws li ib qho - txheej txheej, FBE tsuas yog tso siab rau ntawm epoxy zaj duab xis rau txhua txoj haujlwm tiv thaiv. Nws yog thermosetting polymer uas tsim ib qho nyuaj, inert barrier.
•3LPE: Qhov no yog qhov sib xyaw ua ke. FBE txheej muab kev tiv thaiv corrosion thiab adhesion rau cov hlau. Cov nplaum nplaum ua kom muaj kev sib raug zoo, thiab txheej txheej polyethylene muab kev tiv thaiv zoo tshaj plaws tiv thaiv kev puas tsuaj rau sab nraud.
2. Mechanical Protection
•FBE: Thaum FBE nyuaj thiab tiv taus kev puas tsuaj, nws cov xwm txheej nyias ua rau nws muaj kev cuam tshuam rau kev puas tsuaj (xws li, cuam tshuam, khawb, av nyuaj) thaum tuav, teeb tsa, thiab rov qab ua dua, tshwj xeeb tshaj yog piv rau 3LPE.
•3LPE: Cov txheej tuab txheej polyethylene ntawm 3LPE muab kev tiv thaiv zoo heev. Nws yog qhov ua tau zoo heev rau kev cuam tshuam, kev puas tsuaj, thiab av kev ntxhov siab, ua rau nws zoo tagnrho rau kev teeb tsa hnyav thiab cov av hnyav.
3. Kev khiav hauj lwm qhov kub thiab txias
•FBE: FBE txheej feem ntau ua tau zoo nyob rau hauv ntau qhov kev khiav hauj lwm kub, feem ntau mus txog 80-100℃(176-212℃F), thiab qee qhov tshwj xeeb FBE systems tuaj yeem nce siab dua. Nws qhov kub hloov pauv iav siab (Tg) tso cai rau nws tswj nws txoj kev ncaj ncees ntawm qhov kub siab.
•3LPE: Cov txheej txheem 3LPE feem ntau yog ntsuas rau kev ua haujlwm tsis tu ncua mus txog 80℃(176℃F). Thaum FBE primer tuaj yeem tswj tau qhov kub thiab txias dua, cov txheej txheej polyethylene tuaj yeem ua kom mos lossis deform yog tias raug kub hnyiab dhau qhov kev txwv no.
4. Adhesion thiab Cathodic Disbondment Resistance
Ob leeg FBE thiab 3LPE (vim nws cov FBE primer) muab cov adhesion zoo rau cov hlau substrate thiab superior tiv thaiv cathodic disbondment. Qhov no yog qhov tseem ceeb rau lub sij hawm ntev - kev ua tau zoo ntawm cathodic tiv thaiv kab ke, uas feem ntau siv ua ke nrog txheej txheej.
5. Kev nqus dej thiab permeability
•FBE: Nws muaj qhov nqus dej tsawg heev thiab permeability, muab kev tiv thaiv zoo tiv thaiv ya raws.
•3LPE: Cov txiaj ntsig los ntawm qhov nqus dej tsawg heev thiab permeability ntawm nws cov polyethylene txheej txheej, muab ib qho kev tiv thaiv zoo dua tiv thaiv dej nkag.
6. Nqi thiab Daim Ntawv Thov
•FBE: Feem ntau pheej yig dua rau ib cheeb tsam los thov vim nws ib leeg - txheej xwm thiab txheej txheem thov yooj yim dua.
•3LPE: Feem ntau kim dua vim muaj ntau- txheej txheem thov txheej txheem thiab cov nqi ntawm cov ntaub ntawv. Txawm li cas los xij, kev tiv thaiv kev siv tshuab ntxiv tuaj yeem ua rau qis dua - cov nqi tu thiab txo kev pheej hmoo ntawm kev puas tsuaj thaum lub sijhawm teeb tsa.
Thaum twg xaiv cov txheej txheem twg?
• Xaiv FBE thaum:
•Lub raj xa dej ua haujlwm ntawm qhov kub siab dua (siab dua 80 degree).
• Mechanical puas raug puas tsuaj thaum lub sij hawm installation thiab ua hauj lwm yog tsawg.
•Tus nqi-kev ua tau zoo yog qhov kev txhawj xeeb tseem ceeb, thiab ib qho kev daws teeb meem - txheej yog txaus.
• Cov tshuaj tiv thaiv zoo heev yog qhov tseem ceeb.
• Xaiv 3LPE thaum:
•Lub raj xa dej yuav raug ntsia rau hauv qhov chaw hnyav uas muaj kev pheej hmoo ntawm kev puas tsuaj (xws li, pob zeb struts, aggressive backfill).
• Ntev- tiv thaiv kev puas tsuaj, cuam tshuam, thiab kev ntxhov siab hauv av yog qhov tseem ceeb.
• Ua haujlwm kub nyob rau hauv tus qauv PE ntau (txog 80 degree).
• Kev tiv thaiv tag nrho thiab kev pab cuam ntev ntev yog qhov tseem ceeb tshaj plaws.
