Txheem: SY / t0413-2002 kev qauv rau polyethylene anticorrosive txheej ntawm faus steel pipeline
GB / t23257-2009 tus qauv txheej txheem rau polyethylene anticorrosive txheej ntawm faus steel pipeline
3. Ib leeg PE anticorrosive steel yeeb nkab
Kev sib piv ntawm ib txheej polyethylene thiab peb-txheej polyethylene
Kev sib piv ntawm ib txheej polyethylene thiab peb-txheej polyethylene
Ib txheej txheej PE anticorrosive steel yeeb nkab siv cov txheej txheem tshuaj tsuag (tseem hu ua kab hlau rhuav) kom tig cov yeeb nkab steel rhuab los ntawm nruab nrab zaus. Sab saum toj txheej ntawm cov yeeb nkab steel yog ib lub thawv uas muaj polyethylene hmoov, uas yog txau rau ntawm phab ntsa sab nrauv ntawm cov yeeb nkab steel los tsim cov txheej txheem polyethylene. Tus qauv txheem CJ / t120-2008 yas coated composite steel yeeb nkab rau dej.
1. Kev sib xyaw
Cov khoom yog npaj los ntawm epoxy resin, thee tar pitch, antirust pigment, additives thiab hloov amine. Cov khoom muaj qhov zoo ntawm kev ziab sai, zoo adhesion, zoo saj zawg zog, ob-tivthaiv ntim thiab yooj yim siv. Nws muaj cov yam ntxwv ntawm acid, alkali, ntsev, dej thiab roj kuj.
2. Cov yam ntxwv thiab kev siv
Cov xim sib xyaw ua ke cov yam ntxwv ntawm cov neeg kho tshuab siab, lub zog nplaum loj, tshuaj lom neeg nruab nrab corrosion ntawm epoxy resin thiab dej tsis kam, microbial tsis kam thiab cog hauv paus tsis kam ntawm asphalt. Nws yog kev ua haujlwm siab tiv thaiv corrosion rwb thaiv tsev txheej. Cov khoom muaj tshuaj tiv thaiv zoo thiab dej tsis kam.
Nws muaj feem xyuam rau kev tiv thaiv corrosion ntawm cov roj, roj thiab cov kav dej, kais dej, roj, kav dej, roj refineries, tshuaj nroj tsuag thiab dej phwj tuaj kho. Nws tseem tuaj yeem siv los tiv thaiv corrosion ntawm ntug dej hiav txwv roj drilling platforms thiab underwater qhov chaw ntawm nkoj, nrog rau kev tiv thaiv corrosion ntawm mines thiab cov khoom siv hauv av.
High density polyethylene tsho tiv thaiv corrosion qauv: cov yeeb nkab steel yog qhwv nrog high-density polyethylene cov ntaub ntawv, uas muaj cov neeg kho tshuab muaj zog thiab zoo heev corrosion kuj, thiab muaj peev xwm tiv thaiv cov yeeb nkab steel los ntawm kev puas tsuaj los ntawm lwm yam thaum lub sij hawm thauj, installation thiab siv. Antioxidant, ultraviolet stabilizer, carbon dub, thiab lwm yam yuav tsum tau ntxiv rau hauv kev tsim cov tsho sab nrauv. Lub tes tsho polyethylene yog yooj yim rau hnub nyoog. Yog tias nws khaws cia rau hauv qhov chaw qhib, nws yuav tsum tau them nrog tarpaulin thiab lwm yam ntaub ntawv. Qhov chaw stacking yuav tsum nyob deb ntawm qhov chaw kub kub thiab qhov hluav taws kub. Tom qab ua los tiv thaiv corrosion steel yeeb nkab, nws yog txwv tsis pub raug rau lub hnub thiab quenched, txwv tsis pub lub tes tsho polyethylene yog ib qho yooj yim rau tawg thiab cuam tshuam rau cov khoom ua tau zoo thiab kev pab cuam lub neej.
Epoxy hmoov tau coated los ntawm electrostatic txau txheej txheem. Vim qhov teeb meem adhesion ntawm epoxy hmoov impregnation txheej txheem, impregnation ntawm epoxy hmoov tsis tau nrov. Tam sim no, nrog rau kev vam meej ntawm cov tshuaj phosphating tshwj xeeb rau epoxy hmoov impregnation ntawm Sanye, qhov teeb meem adhesion ntawm epoxy hmoov impregnation txheej txheem tau kov yeej thawj zaug, thiab cov txheej txheem tawm ntawm epoxy hmoov impregnation tau pib tshwm.
Lub hauv paus cov ntaub ntawv ntawm cov kav dej los tiv thaiv corrosion muaj xws li cov kav dej kav, cov kav dej ncaj nraim, cov kav dej seamless, thiab lwm yam hauv Suav teb, lawv tau siv dav hauv cov kav dej engineering xws li kev xa dej mus ntev, roj av, tshuaj lom neeg kev lag luam, roj av, cua sov. , kev kho dej phwj tuaj, dej qhov chaw, choj, steel qauv, kev xa dej hauv hiav txwv thiab cov piling.
