Yeeb Nkab :
Ib lub yeeb nkab yog suav tias yog liab qab yog tias nws tsis muaj txheej txheej adhered rau nws.Feem ntau, ib zaug dov ua tiav ntawm lub zeb zeb, cov khoom siv liab qab raug xa mus rau qhov chaw tsim los tiv thaiv lossis txheej txheej nrog cov khoom xav tau (uas yog txiav txim siab los ntawm cov av hauv av ntawm qhov chaw uas cov khoom siv tau siv).Bare yeeb nkab yog hom yeeb nkab uas siv ntau tshaj plaws hauv kev lag luam piling thiab nws feem ntau muab tso rau hauv av rau kev siv cov qauv.Txawm hais tias tsis muaj kev tshawb fawb los qhia tias cov yeeb nkab liab qab yog qhov ruaj khov dua li cov yeeb nkab coated rau kev siv piling, cov yeeb nkab liab qab yog cov qauv rau kev lag luam.
Galvanizing yeeb nkab :
Galvanizing los yog galvanization yog ib qho ntawm feem nrov hom steel yeeb nkab txheej.Txawm hais tias cov hlau nws tus kheej muaj ntau yam khoom zoo heev thaum nws los txog rau corrosion kuj thiab tensile lub zog, nws yuav tsum tau coated ntxiv nrog zinc kom tiav zoo dua.Galvanizing tuaj yeem ua tau ntau txoj hauv kev, nyob ntawm qhov muaj ntawm txoj kev.Cov txheej txheem nrov tshaj plaws, txawm li cas los xij, yog kub-dip lossis batch dip galvanizing uas cuam tshuam nrog lub submersion ntawm cov yeeb nkab steel rau hauv da dej ntawm zinc molten.Cov tshuaj tiv thaiv metallurgical tsim los ntawm cov yeeb nkab steel hlau thiab cov zinc ua tiav ntawm cov hlau nto uas muab cov corrosion-resistant zoo tsis muaj nyob rau hauv cov yeeb nkab ua ntej.Lwm qhov zoo ntawm galvanizing yog cov txiaj ntsig zoo.Raws li cov txheej txheem yooj yim thiab tsis tas yuav tsum muaj ntau qhov kev ua haujlwm thib ob thiab tom qab ua tiav, nws tau yog qhov kev xaiv mus rau ntau lub tuam txhab thiab kev lag luam.
FBE - Fusion Bonded Epoxy hmoov txheej yeeb nkab :
Cov yeeb nkab txheej no muab kev tiv thaiv zoo rau cov kav dej me me mus rau qhov loj nrog qhov kub thiab txias (-30C txog 100C).Nws daim ntawv thov feem ntau yog siv rau cov roj, roj, lossis cov kav dej ua haujlwm.Qhov zoo heev adhesion tso cai rau lub sij hawm ntev corrosion kuj thiab kev tiv thaiv ntawm cov kav dej.FBE tuaj yeem siv los ua ob txheej txheej uas muab lub cev muaj zog uas txo kev puas tsuaj thaum tuav, thauj, teeb tsa, thiab ua haujlwm.
Ib txheej Fusion Bonded Epoxy Anticorrosive Yeeb Nkab: Electrostatic zog txheej;
Muab ob npaug rau txheej Fusion Bonded Epoxy Anticorrosive Yeeb Nkab: Fistly hauv qab epoxy hmoov, thiab Tom qab ntawd epoxy hmoov nto.
3PE Epoxy txheej yeeb nkab :
3PE Epoxy coated steel yeeb nkab yog nrog 3 txheej txheej, thawj FBE txheej, nruab nrab yog nplaum txheej, sab nraud polyethylene txheej.3PE txheej yeeb nkab yog lwm yam khoom tshiab tsim los ntawm FBE txheej txheej txij li xyoo 1980s, uas muaj cov nplaum nplaum thiab PE (polyethylene) txheej.3PE tuaj yeem ntxiv dag zog rau cov kav dej ntawm cov khoom siv hluav taws xob, hluav taws xob siab, tsis muaj dej, hnav, tiv thaiv kev laus.
Rau thawj txheej yog fusion bonded epoxy, uas thickness yog loj dua 100μm.(FBE> 100μm)
Cov txheej thib ob yog cov nplaum, uas cov nyhuv yog khi epoxy thiab PE txheej.(AD: 170 ~ 250μm)
Cov txheej thib peb yog PE txheej uas yog polyethylene muaj qhov zoo rau kev tiv thaiv dej, hluav taws xob tiv thaiv thiab tiv thaiv kev puas tsuaj.(φ300-φ1020mm)
Yog li ntawd, 3PE txheej yeeb nkab ua ke nrog qhov zoo ntawm FBE thiab PE.Qhov twg ntau dua thiab dav siv hauv faus pipeline thauj dej, roj thiab roj.
