FBE Txheej: Luv luv rau Fusion Bonded Epoxy, Nws yog hom thermosetting epoxy hmoov. Lub workpiece yog preheated ua ntej electrostatic txau. Cov hmoov melts thiab kho los ntawm chemical cross-txuas, tsim molecular bonding nrog cov cam khwb cia hlau substrate. Zaj duab xis thickness ntawm ib txheej yog li ntawm 300 mus rau 500 μm.
PU Txheej: luv rau polyurethane txheej. Nws yog ob-cov khoom siv ua kua polyurethane, uas tuaj yeem txau thiab kho ntawm qhov kub thiab txias. Raws li cov txheej txheem elastic heev, nws muaj qhov ua tau zoo heev nrog cov yeeb yaj kiab tuab ntawm 800 txog 1500 μm.
Kev sib piv ntawm Qhov Zoo
Qhov zoo ntawm FBE Txheej
Superior anti-corrosion barrier performanceDense thiab pinhole-dawb zaj duab xis muab kev tiv thaiv zoo rau saline-alkali av, dej phwj tuaj thiab stray tam sim no corrosion. Tau tshaj cathodic tiv thaiv kab ke, nws ua hauj lwm raws li tus qauv thawj sab nraud tiv thaiv -corrosion txheej rau ntev - kis tau tus mob pipelines. Kev nyab xeeb rau cov dej zooInternal FBE hauv ob sab phlu yog cov txheej txheem tseem ceeb hauv cov dej haus hauv nroog thiab cov kav dej tiv thaiv hluav taws. Nws lub ntsej muag du tiv thaiv limescale buildup, nrog xoom hnyav kis kab mob. Zoo heev - qhov kub thiab txias stabilityQhov kev xaiv zoo tshaj plaws rau cov kev pab cuam nrog nruab nrab kub txog 100℃. Mature mass industrial applicationWidely sawed for internal and external anti{12}}corrosion treatment of standard fittings and straight pipes, delivering a stability service life of over 50 xyoo.
Qhov zoo ntawm PU txheej
Kev tiv thaiv zoo tshaj plaws Nws tiv thaiv kev tawg thiab chipping nyob rau hauv hnyav tej yam kev mob xws li kev taw qhia drilling, yeeb nkab jacking, gravel backfilling, mine slurry pipelines thiab txoj kab nqes nqes mus rau hauv av. Haum rau qis-kub siv tsis muaj siab- qhov kub thiab txias yuav tsum tau ua ntej. Qhov zoo tshaj plaws rau kev kho ib nrab ntawm flanges, tees, tus kheej - cov pob qij txha thiab cov hlua khi. Zoo heev deformation adaptabilitySiv rau kev tiv thaiv sab nraud ntawm lub luj tshib, hloov tau yooj yim pob qij txha thiab kev sib hais haum- cov seem. Lub txheej stretches me ntsis nrog me me yeeb nkab deformation yam tsis muaj cracking. Superior waterproofing, impermeability thiab huab cua resistanceThe nyiam sab nraud anti-corrosion txheej rau overhead yeeb nkab fittings raug qhib cua.
Kev sib piv tsis zoo
Disadvantages ntawm FBE Txheej
High brittleness: Microcracks yooj yim tshwm sim nyob rau hauv sab nraud cuam tshuam los yog hauv av sib hais haum, ua rau substrate corrosion nkag mus los ntawm cov kab nrib pleb.
High -kub preheating yog yuav tsum tau thaum lub sij hawm tsim kho, ua rau nws tsis yooj yim rau me me tshwj xeeb - zoo li tus fittings thiab nyob rau hauv - kho qhov chaw.
Yooj yim rau brittle cracking nyob rau hauv qis -kub deformation; Kev pheej hmoo siab yog tias FBE siv ib leeg rau cov kav dej hla cov pob zeb.
Disadvantages ntawm PU txheej
Inferior tiv thaiv kom muaj zog corrosion thiab kub kub piv nrog FBE. Ntev -kev pabcuam ntev dua 80℃yuav ua rau cov txheej txheej laus.
Aromatic polyurethane tsis muaj feem xyuam rau cov kav dej haus; Tsuas yog aliphatic PU tuaj yeem siv rau kev siv dej.
Incompatible nrog cathodic tiv thaiv. PU ib leeg muaj lub neej ua haujlwm luv luv thaum faus ntev - lub sij hawm nyob rau hauv cov av corrosive heev.
Kev sib piv ntawm Daim Ntawv Thov Scenario
Daim ntawv thov scenarios rau FBE txheej
Sab hauv los tiv thaiv-corrosion ntawm cov kav dej (txheej txheej txheej rau cov dej kais dej, cov dej rov qab thiab cov kav hluav taws xob tseem ceeb); Sab hauv thiab sab nrauv los tiv thaiv-corrosion rau faus cov kav dej ncaj, flanged tees thiab cov qauv fittings nteg rau hauv cov av nruab nrab; Cov kav dej nqa tau siab -kub tawm thiab cov kav dej tshuaj lom neeg; Thawj tiv thaiv - txheej txheej corrosion rau ntev - cov kav xa hluav taws xob uas muaj kev tiv thaiv cathodic.
Daim ntawv thov scenarios rau PU txheej
Txhawb sab nraud los tiv thaiv-corrosion rau cov kav xa dej: kev taw qhia kev hla hla, cov yeeb nkab jacking, gravel roadbeds, ntug hiav txwv ntsev- alkali zones thiab cov seem uas muaj kev puas tsuaj loj heev;
Txheej tshwj xeeb rau flanges, tus kheej - cov pob qij txha anchors, weld seams thiab kho txheej;
Cov khoom siv hluav taws xob thiab cov kav dej uas muaj kev cuam tshuam loj heev ntawm cov twj tso kua mis;
Hnav- tiv thaiv kev tiv thaiv rau mine pipelines thiab cov kav dej phwj tuaj nqa cov khib nyiab thiab cov khoom siv; Lub luj tshib thiab tees nyob rau hauv cov cheeb tsam uas muaj kev sib haum xeeb hauv av.
Jintai Foundry, Lub Hom Phiaj Zoo Tshaj Plaws Rau Cov Yeeb Nkab Hlau, xa cov khoom zoo tshaj plaws, ua raws li cov qauv tsim nruj thiab txaus siab rau kev lag luam zoo heev. Peb muab cov khoom lag luam ntseeg siab thiab ua tiav tom qab -Kev Pabcuam Muag.
