Peb -Tier Core Structural Composition ntawm 3LPE Sab Nraud Txheej Txheej Txheej Txheej
Tag nrho cov txheej txheem tiv thaiv-corrosion txheej yog nruj me ntsis muab faib ua peb txheej txheej txheem los ntawm cov hlau substrate sab nraud, txhua txheej dais ib qho kev ua haujlwm ywj siab thiab koom tes ua ke los tsim cov txheej txheem tiv thaiv kev sib koom ua ke, thiab txhua txheej muaj cov tuab tuab thiab cov qauv tsim los ntawm thoob ntiaj teb cov raj xa dej tshwj xeeb xws li ISO 21809, DIN 2309, DIN 3. Z245.21:
Thawj Txheej: Fusion Bonded Epoxy Primer (FBE Primer Layer)
Cov txheej txheej nyias no ncaj qha hu rau polished steel yeeb nkab sab nrauv, nrog cov qauv tuab xws li 60μm txog 120μm. Ua ntej txau cov epoxy primer no, tag nrho cov kav hlau steel yuav tsum tau dhau los ua ntej{3}} cov txheej txheem kev kho mob: tua blasting lossis xuab zeb blasting kom tshem tawm cov nplai zeb, xeb, roj thiab hmoov av, mus txog qib kev huv huv ntawm Sa 2.5 thiab cov qauv ntxhib ntawm 50μm-}100μm ntev ntawm cov hlau, uas yog - ntev ntawm cov hlau. matrix. Lub fusion bonded epoxy hmoov muaj ultra{10}} muaj zog chemical bonding force nrog hlau; nws tuaj yeem thaiv qhov kev ua ntawm corrosive ions hauv av, cais cov electrolyte kev sib cuag ntawm cov hlau thiab ib puag ncig sab nraud, thiab tiv thaiv cathodic disbondment defects uas yooj yim tshwm sim hauv qis{12}}cov txheej txheem yas zoo. Txawm hais tias cov txheej txheej polyethylene sab nrauv yog khawb los ntawm kev cuam tshuam sab nraud, epoxy primer tseem tuaj yeem tsim ib qho chaw tiv thaiv corrosion los tiv thaiv xeb;
Ob Txheej: Hloov Polyethylene Adhesive Copolymer Nruab Nrab Txheej
Qhov nruab nrab cov nplaum txheej yog qhov kev hloov pauv kev sib txuas ntawm tus choj epoxy primer thiab hloov tau yooj yim txheej txheej polyethylene, nrog tswj thickness ntawm 170μm thiab 250μm. Cov txheej no yog ua los ntawm cov txiv neej anhydride grafted polyethylene copolymer khoom, nrog dual tshuaj affinity: ib sab tsim ib tug ruaj khov tshuaj daim ntawv cog lus nrog epoxy primer, thiab lwm sab melts thiab fuses nrog txheej PE txheej thaum lub sij hawm hauv internet extrusion wrapping txheej txheem. Yog tias tsis muaj cov txheej txheem hloov pauv no, cov epoxy nruj thiab hloov pauv polyethylene yuav sib cais nyob rau hauv qhov kub hloov pauv, av extrusion thiab hauv av kev sib haum xeeb, ua rau txheej txheej txheej thiab ua tiav tsis ua haujlwm ntawm kev tiv thaiv kev ua haujlwm corrosion. Qhov nruab nrab txheej no kuj ntxiv tsis muaj elasticity kom nqus me ntsis sab nraud extrusion siab los ntawm cov av rov qab;
Txheej Thib Peb: High-Density Polyethylene (HDPE) Cov Txheej Txheem Txheej Txheem
Cov txheej txheej HDPE sab nraud yog cov txheej txheem tseem ceeb thiab cov txheej txheem dej tsis sib haum, pom cov xim dub ribbed yas txheej ntawm cov yeeb nkab steel hauv cov duab txuas, nrog cov tuab ntawm 1.8mm txog 3.7mm raws li cov yeeb nkab sib txawv thiab qhov project load yuav tsum. Siab molecular hnyav HDPE resin xaiv rau ntau lawm nta ultra- tsis tshua muaj dej nqus, zoo heev acid, alkali thiab ntsev tshuaj tiv thaiv, muaj zog tiv thaiv rau hauv av anaerobic microbial yaig, thiab zoo heev cuam tshuam thiab puas kuj. Lub kauv winding extrusion txoj kev tsim cov txheej txheem tau txais los ntawm kev tsim khoom tsim ua ntu zus, seamless txheej cladding yam tsis muaj lub puab tsaig, tshem tawm cov kev pheej hmoo ntawm corrosion los ntawm overlapping seams ntawm winding daim kab xev tiv thaiv -corrosion kav. Cov kev ntxhib los mos zoo nkauj ntawm cov yeeb nkab saum npoo yog tsim los ntawm kev ruaj khov extrusion molding, uas kuj ua rau me ntsis nce kev sib txhuam ntawm lub raj xa dej rov qab siv dua kom tsis txhob muaj cov yeeb nkab zawv zawg txav.
Core Technical Advantages of 3LPE Txheej System Piv nrog rau Lwm Cov Kev Tiv Thaiv -Cov Kev Tiv Thaiv Corrosion
1,ultra-ntev kev pab cuam lub neej nyob rau hauv faus tej yam kev mob: integrated peb - txheej txheem txheej txheem zoo thaiv dej, oxygen, chloride thiab sulfate corrosive media nyob rau hauv av, tsis muaj kev laus tsis ua hauj lwm nyob rau hauv 50 xyoo nyob rau hauv ib txwm kub faus ib puag ncig, deb tshaj 8 -15 xyoo kev pab cuam corrosive voj voog ntawm ib leeg {{6} corrosive;
2, kev ua tau zoo ntawm txhua yam kev ua haujlwm zoo: txheej HDPE txheej tuaj yeem tiv thaiv kev puas tsuaj thaum lub sijhawm thauj mus los, trenching backfilling thiab pob zeb extrusion, txo qis heev ntawm - qhov chaw kho qhov chaw ua haujlwm;
3, kev hloov kho qhov kub thiab txias: qhov ua tiav 3LPE coated steel yeeb nkab tuaj yeem ua haujlwm nyob rau hauv qhov kub thiab txias ntawm - 40℃txog 80 degree, haum rau cov cheeb tsam txias sab qaum teb thiab chaw kub kub hauv av, thiab yuav tsis tawg nyob rau hauv qhov kub thiab txias los yog soften thiab ntws nyob rau hauv kub kub;
4, sib xws nrog cathodic tiv thaiv engineering txuam: FBE primer txheej muaj kev tiv thaiv zoo heev rau cathodic disbondment, thiab tuaj yeem koom tes nrog kev txaus siab tam sim no lossis kev txi anode cathodic tiv thaiv kab ke uas feem ntau siv nyob rau hauv ntev -cov roj thiab cov kav xa hluav taws xob, tsis muaj txheej txheej sib cais los ntawm kev tiv thaiv hluav taws xob ntau dhau;
5, tsis tshua muaj nqi tag nrho lub neej voj voog: txawm hais tias ib qho - sij hawm yuav khoom tus nqi ntawm 3LPE coated steel yeeb nkab yog siab dua me ntsis los tiv thaiv -corrosion steel kav, kev txij nkawm- lub voj voog dawb ntawm ntau tshaj 50 xyoo txiav tawm loj tom qab cov kav dej excavation, kho thiab hloov cov nqi, qhia pom tseeb kev lag luam zoo rau qhov ntev -
