Muaj ntau hom flange sab corrosion, thiab kev tiv thaiv corrosion yog sib txawv raws li lub ntees ntawm kev siv. Cia peb kawm nrog kuv.:
1.What yog txheej xim anti - corrosion?
Los ntawm kev txhuam hniav lossis tshuaj tsuag cov anti - corrosion txheej ntawm ntug flange, ib zaj yeeb yaj kiab tiv thaiv yog tsim rau cais cov xov xwm corrosive. Qhov no yog tus nqi -} siv tau zoo thiab yoog raws.
Hom txheej txheej coating:
Epoxy Resin txheej: Muaj kuab lom ua kua nplaum, haum rau muaj cov pa roj pipeline flanges.
Polyurethane txheej: huab cua tsis kam thiab ua kom tau zoo heev, tsim nyog rau sab nraum zoov lossis nthuav tawm cov raj hluav taws xob, xws li cov pa taws pipelines thiab cua tshuab hluav taws xob.
Fluorocarbon txheej: Muaj Kub Siab Tshaj thiab muaj zog corrosion tsis kam, haum rau ib puag ncig ib puag ncig, xws li kev kub siab thiab siab {}} kub hnyiab.
Chlorinated roj hmab txheej: dej thiab ntsev txau tiv thaiv, feem ntau yog siv rau cov nplaim taws hauv cov tub rog lossis huab ib puag ncig.
2.Qhov yog txheej txheej tiv thaiv - corrosion?
Through processes such as electroplating and hot-dip galvanizing, a layer of corrosion-resistant metal is applied to the flange surface, providing long-lasting protection but at a higher cost.
Hom txheej txheej coating:
Kub - dip galvanizing: lub flange yog impared hauv Molten Daus thiab av corrosion thiab av muaj rau cov roj carbon steel flanges.
Chromium / Nickel Electroplating: cov txheej yog nyias thiab ci, tiv taus cov xim yeeb yaj kiab, thiab yog qhov tsim nyog rau cov xim zoo nkauj thiab qhov tseeb uas yog cov khoom noj ua haus cov khoom siv.
Zinc - plating / zinc - lines}}}}} av noo lossis cov av av noo.
3.Qhov tsis yog - nws yog xim hlau?
Tsis - Cov ntaub ntawv hauv Flange yog thov rau cov Flange Sorting nto lossis sab hauv phab ntsa kom tiav ntawm kev txhim kho ib puag ncig.
Cov Khoom Siv Hauv Cov Khoom Siv:
Polytetrafluoroethylene (ptfe): resistant rau cov muaj zog acids, alkalis, thiab high kub, haum rau flange sealange surgaces hauv tshuaj thiab cov khoom lag luam.
Roj Hmab Linings (xws li Nitrile Roj Hmab thiab Fluororubber): Roj thiab Tshuaj Lom Zem, Cov Khoom Siv Hauv Flange Hauv qis- qhov siab ib puag ncig.
Ceramic Lineings: Siab {- kub thiab hnav {{1} - kub remue roj lossis hmoov txuas xov hluav taws xob
4.What yog tshuaj hloov pauv hloov hloov kho?
Tshuaj lom neeg tsim ib qho oxide lossis phosphate zaj duab xis ntawm Flange nto, feem ntau yog kev ua haujlwm rau kev tiv thaiv adhesion thiab yooj yim corrosion tiv thaiv.
Hom:
Phosphaating: tsim cov yeeb yaj kiab phosphate rau saum npoo ntawm cov roj carbon hlau flanges, ua yeeb yam raws li cov pleev xim primer los tiv thaiv cov hlua khi.
Blackening (oxidation): Tsim cov yeeb yaj kiab oxide dub rau saum npoo ntawm steel flanges. Qhov no feem ntau siv rau cov laj thawj zoo nkauj thiab lub hauv paus tiv thaiv nyob rau sab hauv tsev, qis- corrosion ib puag ncig.
