Xim tiv thaiv xeb

Xim tiv thaiv xeb yog ib hom tshuaj uas ua lub luag haujlwm tiv thaiv xeb, tiv thaiv kev xeb hlau thiab txhim kho cov nyhuv tiv thaiv ntawm cov xim pleev xim rau ntawm qhov chaw hlau. Lub luag haujlwm ntawm xim tiv thaiv xeb tuaj yeem muab faib ua ob pawg: lub cev tiv thaiv xeb thiab tshuaj tiv thaiv xeb, uas cov tshuaj tiv thaiv xeb tuaj yeem muab faib ua hom kev tiv thaiv xeb thiab hom kev ua electrochemical thib ob. Cov tshuaj uas ua lub luag haujlwm tiv thaiv xeb feem ntau suav nrog hmoov liab liab, hmoov hlau liab, hmoov hlau titanium sib xyaw, hmoov txhuas tripolyphosphate zinc thiab lwm yam. Tam sim no, xim tiv thaiv xeb feem ntau yog siv rau hauv cov txheej tiv thaiv xeb, thiab tus nqi ntawm cov txheej tiv thaiv xeb suav txog 6% -8.5%.

Qhov txawv ntawm xim Anti-rust thiab xim pleev yog dab tsi?

Xim tiv thaiv xeb yog ib hom xim uas tuaj yeem tiv thaiv cov hlau ntawm cov tshuaj lom neeg lossis hluav taws xob xeb ntawm huab cua, dej hiav txwv, thiab lwm yam. Xim tiv thaiv xeb lub cev thiab tshuaj lom neeg, xws li hlau liab, hmoov txhuas, graphite tiv thaiv xeb, txhuas liab, zinc daj tiv thaiv xeb xim thiab lwm yam.

Xim yog ib qho tshuaj sib xyaw ua ke uas npog cov khoom ntawm qhov chaw, tiv thaiv, kho kom zoo nkauj, cim thiab lwm yam tshwj xeeb, thiab tsim cov zaj duab xis khov kho uas lo rau ntawm qhov chaw ntawm cov khoom thiab muaj qee lub zog thiab kev sib txuas ntxiv mus.

1. Cov haujlwm sib txawv:

Cov xim tiv thaiv xeb muaj cov yam ntxwv ntawm kev tiv thaiv xeb thiab tiv thaiv xeb, zaj duab xis yog tawv, ua tau zoo heev, thiab qhov nyuaj yog siab dua li cov xim ib txwm muaj. Cov xim ib txwm muaj tsis muaj kev ua haujlwm tiv thaiv xeb, vim tias cov khoom siv zaj duab xis xim ib txwm muaj yog alkyd resin, los ntawm kev oxidation thiab ziab, qhov nyuaj tsis zoo, qib kev nplaum sib txawv.

2. Lub neej ua haujlwm sib txawv:

Cov xim tiv thaiv xeb siv tau 5-8 xyoo yog tias sib phim. Cov xim ib txwm siv sab nraum zoov li 3 xyoos. Tom qab ob lossis peb xyoos, nws yooj yim poob, ploj thiab ua hmoov.

3. Ntau hom sib txawv:

Xim tiv thaiv xeb: xim phenolic tiv thaiv xeb, xim alkyd tiv thaiv xeb (hlau liab, grey, liab lead), xim roj hmab chlorinated tiv thaiv xeb, xim epoxy tiv thaiv xeb (zinc phosphate tiv thaiv xeb xim, liab lead tiv thaiv xeb xim, zinc nplua nuj tiv thaiv xeb xim, hlau liab tiv thaiv xeb xim), thiab lwm yam

Xim: Muaj ntau hom xim, xim tiv thaiv xeb kuj yog ib hom xim, ntxiv rau xim kuj suav nrog xim ntoo, xim hauv pem teb, xim phab ntsa sab nraud, xim pob zeb, xim ntau xim, xim txhuas alloy, xim tiv taus hluav taws, xim latex thiab lwm yam.

Yim txoj kev qhia rau kev txhim kho yav tom ntej ntawm cov xim tiv thaiv xeb

Ua ntej, kev tsim cov xim pleev xim tiv thaiv xeb thiab xim pleev rau saum cov qauv hlau.

Cov tshuaj primer tiv thaiv xeb uas siv dej yuav tsum daws qhov teeb meem ntawm cov substrate "flash rust" thiab kev tiv thaiv dej tsis zoo, thiab qhov nce ntawm qee cov emulsifier tshiab uas tsis muaj emulsifier tau txhim kho nws lub npe tiv thaiv dej tsis zoo, thiab yav tom ntej yuav tsum tsom mus rau kev daws cov teeb meem ntawm kev tsim kho thiab kev siv. Ua ib lub topcoat, nws yog feem ntau los txhim kho nws qhov kho kom zoo nkauj thiab kev ua haujlwm ntev raws li qhov xwm txheej ntawm kev ua kom muaj kev tiv thaiv.

Qhov thib ob yog tsim cov xim pleev xim uas muaj cov khoom khov kho thiab cov tshuaj tsis muaj kuab lom.

Kev khawb av, cov platforms offshore thiab cov haujlwm loj loj tiv thaiv xeb hauv cov haujlwm tiv thaiv xeb ultra-ruaj khov ntawm cov txheej txheem yog qhov ceev heev, kev ua lag luam tam sim no yog cov tuam txhab txawv teb chaws thiab cov khoom xa tuaj. Cov khoom lag luam hauv Suav teb feem ntau yog nyob rau hauv theem kev txawj ntse, lub zog kev lag luam, kev ruaj ntseg zoo thiab lub koob npe nrov ntawm cov khoom thiab lwm yam kev sib txawv ntawm lub zog nrog cov teb chaws txawv teb chaws, nws nyuaj rau nkag mus rau hauv kev ua lag luam. Txhawm rau ua tiav qhov no, ua ntej tshaj plaws, yuav tsum tau ua rau kev siv zog hauv kev txhim kho kev txawj ntse, tshwj xeeb tshaj yog kev tsim cov xim tiv thaiv xeb tsis muaj lead thiab chromium, uas yog, raws li zinc phosphate thiab txhuas tripolyphosphate tiv thaiv xeb primer.

Qhov thib peb yog tsim cov tshuaj pleev xim nplua nuj zinc uas muaj dej.

Cov tshuaj pleev xim nplua nuj inorganic zinc thiab cov tshuaj pleev xim nplua nuj inorganic zinc uas muaj dej yog ib qho ntawm cov tshuaj pleev xim uas ua haujlwm ntev, tab sis lawv yog cov tshuaj pleev xim uas muaj cov kuab tshuaj. Cov tshuaj pleev xim nplua nuj inorganic zinc uas muaj dej nrog cov potassium silicate ntau modulus ua cov khoom siv hauv paus yog cov tshuaj pleev xim tiv thaiv xeb ua haujlwm tau sim los ntawm kev xyaum thiab muaj peev xwm tsim kho.

Qhov thib plaub yog kev tsim cov khoom siv hloov pauv cua sov uas kho tau cov txheej txheem tiv thaiv xeb uas tiv taus kub.

Cov khoom siv hloov pauv cua sov xav tau cov txheej tiv thaiv xeb uas muaj kev tiv thaiv cua sov siab thiab kev ua haujlwm thermal, thiab cov txheej epoxy amino uas siv tam sim no yuav tsum tau kho ntawm 120 ° C thiab xav tau ntau txheej, uas tsis tuaj yeem siv rau ntawm cov khoom siv loj.

Qhov thib tsib yog tsim kom muaj ib txheej uas tuaj yeem kho tau ntawm chav tsev kub thiab yooj yim rau kev siv.

Lub ntsiab lus tseem ceeb yog nrhiav qhov sib npaug zoo tshaj plaws ntawm kev tiv thaiv xeb, kev hloov pauv cua sov thiab kev tsim kho ntawm cov txheej.

Qhov thib rau yog kev tsim cov txheej txheem tiv thaiv xeb flake.

Mica hlau oxide (MIO) muaj kev tiv thaiv dielectric zoo heev, kev tiv thaiv kev laus hauv huab cua thiab kev thaiv kev ua haujlwm, thiab yog siv dav ua primer thiab xim pleev xim sab saum toj hauv Western Europe.

Xya, kev tsim cov roj hmab chlorinated series ntawm cov tshuaj tiv thaiv xeb hloov pauv.

Vim tias cov roj hmab chlorinated yog ib qho khoom siv, kev tsim kho yooj yim, tiv taus dej, tiv taus roj, tiv taus huab cua laus zoo heev, siv dav hauv kev tsim nkoj, kev tiv thaiv xeb hauv kev lag luam thiab lwm yam teb, muaj kev lag luam dav hauv Suav teb. Txawm li cas los xij, vim tias kev tsim cov roj hmab chlorinated siv CC1 ua cov kuab tshuaj, cov txheej ozone raug rhuav tshem.

Qhov thib yim yog kev tsim cov khoom siv tiv thaiv xeb uas tsis muaj organic hloov kho.

Nyob rau xyoo tas los no, kev siv cov organic emulsion hloov kho pob zeb los txhim kho nws lub zog thiab qhov nruab nrab tsis kam, dav siv rau hauv kev lag luam hauv pem teb. Ntawm lawv, epoxy dej emulsion (lossis epoxy raws li cov kuab tshuaj) tau tsim sai tshaj plaws, uas hu ua polymer cement.
