3pe anticorrosive steel yeeb nkab yog cov yeeb nkab steel nrog cov khoom siv niam txiv nrog rau seamless steel yeeb nkab, kauv steel yeeb nkab thiab ncaj seam steel yeeb nkab ua tiav los ntawm txheej txheej anticorrosive. Peb txheej txheej ntawm polyethylene (3PE) anticorrosion txheej nrog nws zoo corrosion kuj, dej thiab roj permeability thiab txhua yam khoom, thiab lwm yam, nyob rau hauv cov roj pipeline kev lag luam tau dav siv.
(A) kev sib xyaw ua ke
3PE anti-corrosion feem ntau muaj 3 txheej:
The first layer of epoxy powder (FBE>100 hli)
Qhov thib ob txheej ntawm cov nplaum (AD) 170 ~ 250um
Peb txheej ntawm polyethylene (PE) 1.8 ~ 3.7mm
Hauv kev xyaum, peb cov ntaub ntawv yuav raug muab sib xyaw thiab fused rau hauv ib qho, tom qab ua kom nws ruaj khov ua ke nrog cov yeeb nkab steel los tsim cov txheej txheem zoo tiv thaiv corrosion. Txoj kev ua feem ntau muab faib ua ob hom: winding hom thiab puag ncig pwm txheej hom.
3PE anticorrosive steel yeeb nkab txheej kuj hu ua (peb-txheej polyethylene anticorrosive txheej), yog European 2PE anticorrosive txheej thiab North America cov dav siv epoxy hmoov anticorrosive steel yeeb nkab txheej (FBE) ntse ua ke ntawm ib tug tshiab anticorrosive steel yeeb nkab txheej. Nws tau raug lees paub thiab siv thoob plaws ntiaj teb rau ntau tshaj kaum xyoo.
(B) siv cov khoom siv
3PE anticorrosive steel yeeb nkab txheej yog txheej hauv qab hauv kev sib cuag nrog cov nplaim ntawm cov yeeb nkab steel yog epoxy hmoov anticorrosive txheej, cov txheej nruab nrab yog cov nplaum copolymerization nrog ib ceg qauv ntawm pawg ua haujlwm. Cov txheej txheej saum npoo yog high-density polyethylene anticorrosion txheej.
3pe anticorrosion txheej synthesizes epoxy resin thiab polyethylene cov ntaub ntawv nrog siab impermeability thiab siab mechanical zog. Txog tam sim no nws tau lees paub thoob ntiaj teb raws li cov raj xa dej los tiv thaiv cov txheej txheem nrog cov txiaj ntsig zoo tshaj plaws thiab kev ua tau zoo, thiab yog li siv rau ntau qhov haujlwm.
3PE anti-corrosion steel yeeb nkab yog tsim rau thee mine underground water supply and drainage, underground slurry spraying, positive and negative pressure ventilation, gas pumping, fire sprinkling and other pipes networks. Thermal fais fab nroj tsuag txheej txheem dej slag, backwater thauj pipeline. Nws muaj kev siv tau zoo heev rau cov kav dej xa dej ntawm cov tshuaj tiv thaiv kab mob thiab cov tshuaj txau. Cable tiv thaiv casing rau hluav taws xob, kev sib txuas lus thiab txoj kev loj. Haum rau kev siv dej hauv tsev siab, cua sov network cua sov, dej ua haujlwm, roj tsheb thauj mus los, cov kav dej faus. Petroleum tsheb thauj mus los pipeline, tshuaj thiab tshuaj kev lag luam, luam ntawv thiab dyeing thiab lwm yam lag luam los thauj corrosive media txheej txheem pipeline. Kev kho cov dej phwj tuaj tawm cov yeeb nkab, cov kav dej phwj tuaj thiab lub pas dej lom neeg tiv thaiv kev ua haujlwm. Cov kav dej ua liaj ua teb, cov kav dej sib sib zog nqus, cov kav dej thiab lwm cov tes hauj lwm thiab lwm yam.
