3LPE Txheej yog dab tsi? Phau Ntawv Qhia Kom Paub Txog Nws Peb -Txheej Txheej Txheej Txheem

Cov kav hlau hlau yog cov pob txha ntawm cov txheej txheem niaj hnub no, thauj cov peev txheej tseem ceeb xws li roj, roj, thiab dej hla ntau qhov deb. Txawm li cas los xij, cov kav dej no tau raug cuam tshuam tas li rau qhov chaw hnyav, tshwj xeeb tshaj yog nyob hauv av, qhov chaw uas lawv ntsib kev hem thawj ntawm corrosion tsis tu ncua. Corrosion tuaj yeem ua rau xau, ib puag ncig kev puas tsuaj, thiab kev puas tsuaj loj, ua rau muaj txiaj ntsig zoo tiv thaiv - tiv thaiv corrosion tseem ceeb. Ntawm cov txheej txheem txheej txheej sab nraud, 3LPE (Peb-Txheej Polyethylene) txheej yog ib qho kev daws teeb meem rau nws cov kev ua tau zoo thiab kev ua haujlwm ntev. Tab sis 3LPE txheej yog dab tsi, thiab nws li cas peb - txheej txheej muab kev tiv thaiv zoo rau cov kav hlau? Hebei Huayang Steel Yeeb Nkab Co., Ltd., tus kws tshaj lij hauv kev tiv thaiv -cov yeeb nkab kev daws teeb meem, delves rau hauv kev tshawb fawb thiab cov txiaj ntsig ntawm cov txheej txheem txheej txheem no.

Qhov Kev Nyuaj Siab Tsis Txaus Siab ntawm Corrosion rau cov kav dej

Corrosion yog cov txheej txheem electrochemical uas degrades hlau, xa rov qab rau lawv cov ntaub ntawv oxidized ruaj khov dua. Rau faus steel pipelines, thawj cov ntaub ntawv ntawm corrosion muaj xws li:

•Electrochemical Corrosion: Ua los ntawm qhov sib txawv ntawm cov hluav taws xob muaj peev xwm nyob rau hauv cov yeeb nkab saum npoo ntawm cov electrolyte (cov av noo).

•Microbial Induced Corrosion (MIC): Qee cov kab mob hauv cov av tuaj yeem ua kom corrosion.

•Stray Current Corrosion: Ua los ntawm cov hluav taws xob sab nraud cuam tshuam nrog cov kav dej.

• Mechanical Damage: Abrasion los ntawm av txav los yog kev teeb tsa tuaj yeem cuam tshuam cov txheej txheem tiv thaiv, nthuav tawm cov hlau.

Yog tias tsis muaj kev tiv thaiv txaus, cov txheej txheem no tuaj yeem cuam tshuam sai rau kev ncaj ncees ntawm lub raj xa dej, ua rau kev kho tus nqi, kev cuam tshuam kev ua haujlwm, thiab kev nyab xeeb.

Taw qhia 3LPE Txheej: Ntau yam -Txoj Kev Tiv Thaiv

3LPE txheej yog lub Hoobkas- siv, ntau- txheej tiv thaiv- xeb txheej txheem tsim los muab kev tiv thaiv ntev - cov kav dej steel ua haujlwm hauv ntau qhov chaw thiab nyuaj. Raws li nws lub npe qhia, nws muaj peb txheej sib txawv, txhua qhov ua rau muaj kev tiv thaiv tag nrho:

Txheej 1: Fusion Bonded Epoxy (FBE)

Cov txheej sab hauv tshaj plaws yog siab -Kev ua tau zoo Fusion Bonded Epoxy (FBE). Cov txheej no yog siv ncaj qha mus rau lub pre- ntxuav thiab rhuab steel yeeb nkab nto. FBE yog thermosetting hmoov txheej uas, thaum rhuab, melts thiab tsim ib tug nruam, uniform zaj duab xis. Nws cov khoom tseem ceeb muaj xws li:

•Zoo heev Adhesion: FBE tsim ib tug muaj zog tshuaj daim ntawv cog lus nrog cov hlau nto, tiv thaiv cathodic disbondment (ib qho kev tsis ua hauj lwm mechanism uas txheej txheej cais los ntawm cov yeeb nkab nyob rau hauv cathodic tiv thaiv).

•High Corrosion Resistance: Nws muab kev tiv thaiv zoo heev tiv thaiv cov kab mob corrosive thiab muaj tshuaj lom neeg zoo.

•High Dielectric zog: Muaj superior hluav taws xob rwb thaiv tsev, tiv thaiv stray tam sim no corrosion.

Txheej 2: Copolymer Adhesive

Siv cov txheej txheem FBE kho, txheej thib ob yog cov nplaum copolymer. Cov txheej no ua raws li tus choj tshuaj, tsim kom muaj kev sib raug zoo ntawm FBE thiab txheej txheej polyethylene. Cov nplaum feem ntau yog hloov kho polyethylene lossis polypropylene, tsim kom yaj thiab ntws, ua kom muaj kev hloov pauv seamless thiab muaj zog adhesion ntawm cov khoom sib txawv. Nws lub luag haujlwm tseem ceeb yog los xyuas kom meej lub sijhawm ntev - kev ncaj ncees ntawm ntau - txheej txheej los ntawm kev tiv thaiv delamination.

Txheej 3: Extruded Polyethylene (PE) lossis Polypropylene (PP)

Cov txheej txheej sab nraud yog txheej tuab ntawm extruded polyethylene (PE) lossis polypropylene (PP). Cov txheej no yog siv los ntawm cov nplaum, muab cov kev tiv thaiv thawj zaug rau tag nrho cov kab ke. Polyethylene yog xaiv rau nws:

•High Mechanical Strength: Ua tau zoo heev rau kev puas tsuaj, cuam tshuam, thiab kev ntxhov siab hauv av thaum tuav, teeb tsa, thiab ua haujlwm.

• Kev nqus dej tsawg: Muab cov khoom tiv thaiv impermeable tiv thaiv cov dej nkag.

•Zoo hluav taws xob rwb thaiv tsev: Ntxiv txhim khu kev tiv thaiv cathodic.

•UV Resistance: Tiv thaiv kev degradation los ntawm tshav ntuj thaum lub sij hawm cia thiab saum toj no - raug av.

Cov txiaj ntsig Synergistic ntawm Peb - Txheej Txheej Txheej

Lub zog ntawm 3LPE txheej yog nyob rau hauv kev sib koom ua ke ntawm peb txheej:

•FBE muab kev tiv thaiv corrosion zoo tshaj thiab adhesion rau hlau.

• Cov nplaum ua kom muaj zog, ruaj khov ntawm FBE thiab PE.

•PE muaj kev tiv thaiv zoo tiv thaiv sab nraud.

Cov txheej txheem ntau- txheej txheej no tsim ib qho kev tiv thaiv zoo heev thiab impermeable uas tiv thaiv cov yeeb nkab steel los ntawm cov khoom corrosive, mechanical puas tsuaj, thiab cathodic disbondment, ua kom lub sij hawm ntev - kev ncaj ncees thiab kev nyab xeeb ntawm cov kav dej.

Daim ntawv thov txheej txheem ntawm 3LPE txheej

Daim ntawv thov ntawm 3LPE txheej yog txheej txheem txheej txheem Hoobkas nrog ob peb kauj ruam tseem ceeb:

1.Pipe Ntxuav: Cov yeeb nkab steel nto yog huv si los ntawm kev txhaj tshuaj blasting kom tshem tawm cov xeb, nplai, thiab cov kab mob, ua tiav qhov ze ntawm - cov hlau dawb (Sa 2.5 lossis Sa 3.0).

2.Preheating: Cov yeeb nkab ntxuav yog preheated rau qhov kub thiab txias kom yooj yim rau FBE daim ntawv thov thiab xyuas kom zoo adhesion.

3.FBE Daim Ntawv Thov: FBE hmoov yog electrostatically txau rau ntawm cov yeeb nkab kub saum npoo, qhov chaw nws melts, ntws, thiab kho kom tsim ib txheej txheej.

4.Adhesive Application: Thaum FBE tseem kub, cov nplaum copolymer yog siv.

5.Polyethylene / Polypropylene Daim Ntawv Thov: Qhov kawg PE / PP txheej yog extruded rau hauv cov yeeb nkab, fusing nrog cov nplaum.

6.Cooling thiab Quenching: Cov yeeb nkab coated yog txias, feem ntau nrog dej, kom solidify txheej.

7.Inspection thiab Testing: Cov txheej txheej tiav dhau los soj ntsuam kev tswj xyuas kom zoo, suav nrog kev kuaj xyuas hnub so (pinhole test), kev kuaj adhesion, ntsuas thickness, thiab kev ntsuam xyuas qhov cuam tshuam.
