Epoxy hmoov anticorrosive steel kav muaj qhov zoo tshaj plaws corrosion kuj, ua rau lawv cov ntawv thov thoob plaws ntau yam ntawm tib neeg kev tsim khoom, kev ua haujlwm, thiab lub neej txhua hnub.
Epoxy resin, ib hom tshuaj tiv thaiv, yog siv los tsim cov epoxy hmoov anticorrosive kauv steel kav. Cov kav dej no khav theeb kho ceev ceev, luv curing lub sij hawm, thiab cov txheej txheem siab, nrog rau tag nrho cov txheej txheem ntau lawm streamlined los ntawm ib tug conveyor kab. Cov txheej tuaj yeem siv rau hauv ib txheej uas siv tshuab electrostatic txau. Cov epoxy hmoov anticorrosive kauv steel kav qhia tau zoo heev acid thiab alkali tsis kam, ua rau lawv ua haujlwm ib txwm nyob rau hauv ntau qhov kub thiab txias. Tsis tas li ntawd, txheej txheej no yog ib puag ncig tus phooj ywg, cuam tshuam-resistant, kub-resistant, thiab muaj cov khoom zoo bending.
Cov kav dej no pom kev siv dav hauv cov haujlwm xws li roj, tshuaj, roj av, cua sov, dej phwj tuaj, dej haus, chaw ua dej hiav txwv, kev tsim kho, thiab kev tsuas.
Corrosion yog hais txog cov tshuaj thiab electrochemical los ntawm cov khoom siv hlau thiab ib puag ncig xov xwm ntawm cov hlau, uas ua rau cov khoom degradation thiab puas. Cov kav xa hluav taws xob feem ntau yog tshwm sim los ntawm cov khoom siv corrosive xws li yaj cov pa roj carbon dioxide, H2S, Cl-, taug qab cov pa oxygen, thiab cov kab mob, uas ncaj qha cuam tshuam nrog hlau los pib tshuaj lom neeg corrosion.
3PE anticorrosive steel yeeb nkab tsim cov txheej txheem pib nrog daim ntawv thov ntawm epoxy primer ntawm cov yeeb nkab steel nto. Tom qab ntawd, cov yeeb nkab yog pub rau hauv thaj tsam txheej ntawm ib qho kev sib hloov ceev, qhov twg ib txheej ntawm cov nplaum zaj duab xis nrog qee qhov tuab thiab ntom yog extruded thiab qhwv ib ncig ntawm cov yeeb nkab nto. Thaum cov nplaum tseem molten, lub extruder thib ob extrudes ib zaj duab xis polyethylene, uas yog qhwv ib ncig ntawm cov nplaum los tsim cov txheej.
Cov txheej peb-txheej polyethylene anticorrosive txheej muaj xws li FBE (Fusion Bonded Epoxy) hauv qab txheej nrog lub thickness ntawm kwv yees li 50 mus rau 128 microns, copolymer nplaum txheej nruab nrab ntawm ib ncig ntawm 200 microns, thiab txheej txheej polyethylene ntawm kwv yees li 3 millimeters. Cov qauv no ua ke nrog kev ua haujlwm siab, oxygen tsis kam, tshuaj tiv thaiv corrosion, thiab cathodic disbondment tsis kam ntawm FBE nrog rau cov dej tsis kam, hluav taws xob rwb thaiv tsev, thiab kev puas tsuaj rau cov khoom siv high-density polyethylene rau hauv cov organic tag nrho. Nws nta muaj zog adhesion rau cov yeeb nkab nto, zoo hluav taws xob rwb thaiv tsev, cuam tshuam tsis kam, kev pab lub neej ntev, thiab qis cathodic tiv thaiv tam sim no ntom, uas tsuas yog 1 txog 38A / m2.
Los ntawm qhov kev xav mus sij hawm ntev, nws qhov zoo tshaj tus nqi-kev ua tau zoo yog pom tseeb. 3PE anticorrosive steel yeeb nkab qauv suav nrog epoxy hmoov txheej (FBE> 100um) raws li thawj txheej, txheej nplaum (copolymer nplaum) ntawm 170 txog 250um raws li txheej thib ob, thiab polyethylene (PE) txheej ntawm 2.5 txog 3.7mm raws li peb txheej. Peb cov ntaub ntawv no yog nruj nreem fused ua ke thiab sib koom ua ke rau cov yeeb nkab steel, tsim cov yeeb nkab nyias phab ntsa. Preheating yog ua raws li cov txheej txheem epoxy hmoov. Thaum cov hmoov los rau hauv kev sib cuag nrog cov yeeb nkab phab ntsa, nws melts thiab adheres rau nws. Tom qab ntawd, kev nqus dej yog siv los txo qhov kub hauv cov yeeb nkab, txo cov hmoov av adhering rau cov yeeb nkab phab ntsa.
