Anti-xeb xim

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

Qhov txawv ntawm Anti-xeb xim thiab xim yog dab tsi?

Antirust xim yog ib hom xim uas tuaj yeem tiv thaiv cov xim hlau los ntawm cov tshuaj lom neeg lossis electrochemical corrosion ntawm huab cua, dej hiav txwv, thiab lwm yam. Lub cev thiab tshuaj tiv thaiv xeb xim, xws li hlau liab, txhuas hmoov, graphite anti-xeb xim, liab lead, zinc daj los tiv thaiv xeb thiab lwm yam.

Cov xim pleev xim yog cov tshuaj sib xyaw ua ke uas ruaj khov rau saum npoo ntawm cov khoom, tiv thaiv, kho kom zoo nkauj, cov cim thiab lwm yam tshwj xeeb, thiab tsim cov yeeb yaj kiab uas ruaj khov rau saum npoo ntawm cov khoom thiab muaj qee lub zog thiab txuas ntxiv.

1. Cov haujlwm sib txawv:

Anti-xeb xim muaj cov yam ntxwv ntawm kev tiv thaiv corrosion thiab tiv thaiv xeb, zaj duab xis yog tawv, kev ua tau zoo heev, thiab hardness siab dua li cov xim zoo tib yam. Ordinary xim tsis muaj kev tiv thaiv xeb, vim tias cov khoom siv xim zoo tib yam yog alkyd resin, los ntawm oxidation thiab ziab, tsis zoo hardness, adhesion qib sib txawv.

2. Lub neej ua haujlwm sib txawv:

Anti-xeb xim tuaj yeem siv rau 5-8 xyoo nyob rau hauv rooj plaub ntawm kev sib txuam. Cov xim zoo nkauj feem ntau yog siv sab nraum zoov li 3 xyoos. Tom qab ob lossis peb xyoos, nws yog ib qho yooj yim kom poob tawm, ploj thiab hmoov.

3. Ntau hom:

Anti-xeb xim: phenolic anti-xeb xim, alkyd anti-xeb xim (hlau liab, grey, liab lead), chlorinated roj hmab anti-xeb xim, epoxy anti-xeb xim (zinc phosphate anti-xeb xim, liab lead anti-xeb xim, zinc nplua nuj anti-xeb xim, hlau liab anti-xeb xim), thiab lwm yam

Xim: Cov xim nplua nuj ntau yam, xim pleev xim los tiv thaiv xeb kuj yog ib hom xim xim, ntxiv rau cov xim pleev xim kuj tseem muaj cov xim ntoo, xim hauv pem teb, xim phab ntsa sab nrauv, xim pob zeb, xim xim ntau xim, xim xim txhuas alloy, xim hluav taws xob, xim pleev xim thiab lwm yam.

Yim cov lus qhia rau kev txhim kho yav tom ntej ntawm cov xim pleev xim

Ua ntej, txoj kev loj hlob ntawm cov dej-raws li anti-xeb primer thiab sab saum toj xim rau steel qauv.

Water-based anti-xeb primer yuav tsum daws qhov kev ntxhov siab ntawm substrate "flash rust" thiab cov dej tsis zoo, thiab qhov nce ntawm qee qhov tshiab emulsifier-dawb emulsions tau txhim kho nws cov dej tsis zoo lub npe, thiab yav tom ntej yuav tsum tsom mus rau kev daws teeb meem ntawm kev tsim kho thiab kev ua haujlwm. Raws li ib tug topcoat, nws yog tsuas yog los txhim kho nws cov kho kom zoo nkauj thiab durability nyob rau hauv cov xwm txheej ntawm kev ua kom muaj kev tiv thaiv muaj nuj nqi.

Qhov thib ob yog los tsim cov txheej txheem ntawm cov ntsiab lus siab thiab hnyav-dawb anti-xeb xim.

Drilling, offshore platforms thiab loj-scale anti-xeb tej yaam num nyob rau hauv lub ultra-durable anti-xeb muaj nuj nqi ntawm cov txheej txheem yuav tsum tau ceev heev, lub lag luam tam sim no yeej ib txwm txawv teb chaws cov lag luam thiab cov khoom txawv teb chaws nyob. Tuam Tshoj cov khoom lag luam feem ntau yog nyob rau hauv cov txheej txheem kev, kev lag luam lub zog, kev ruaj ntseg zoo thiab cov khoom lag luam lub koob npe nrov thiab lwm yam kev sib txawv ntawm lub zog nrog txawv teb chaws, nws nyuaj rau nkag mus rau hauv kev ua lag luam. Txog rau qhov kawg no, ua ntej ntawm tag nrho cov, kev siv zog yuav tsum tau ua hauv kev tsim kho, tshwj xeeb tshaj yog kev txhim kho cov hlau lead-dawb thiab chromium-free anti-xeb xim primer, uas yog, raws li zinc phosphate thiab txhuas tripolyphosphate anti-xeb primer.

Qhov thib peb yog los tsim cov dej-raws li zinc-nplua nuj primer.

Inorganic zinc-nplua nuj primer thiab dej-raws li inorganic zinc-nplua nuj primer yog ib qho ntawm cov ua yeeb yam ntev, tab sis lawv yog cov txheej txheem hnyav. Cov dej-raws li inorganic zinc-nplua nuj primer nrog siab modulus poov tshuaj silicate raws li cov khoom siv hauv paus yog lub siab ua haujlwm tiv thaiv xeb txheej sim los ntawm kev xyaum thiab muaj peev xwm txhim kho.

Qhov thib plaub yog kev txhim kho ntawm cov khoom siv hluav taws xob hloov kho cov cua sov resistant anti-xeb txheej.

Thaum tshav kub kub exchangers xav tau cov txheej txheem los tiv thaiv xeb nrog kev kub siab thiab thermal conductivity, thiab tam sim no siv epoxy amino txheej yuav tsum tau kho ntawm 120 ° C thiab yuav tsum tau ntau txheej, uas tsis tuaj yeem siv rau ntawm cov khoom loj.

Qhov thib tsib yog los tsim cov txheej txheem uas tuaj yeem kho tau ntawm chav tsev kub thiab yooj yim rau kev thov.

Lub ntsiab lus tseem ceeb yog txhawm rau nrhiav qhov sib npaug zoo tshaj plaws ntawm kev tiv thaiv xeb, kev hloov hluav taws xob thiab kev tsim kho ntawm cov txheej txheem.

Qhov thib rau yog kev txhim kho ntawm flake anti-xeb txheej.

Mica hlau oxide (MIO) muaj qhov zoo tshaj plaws dielectric tsis kam, atmospheric aging kuj thiab thaiv muaj nuj nqi, thiab yog dav siv los ua primer thiab sab saum toj xim nyob rau hauv Western Europe.

Xya, txoj kev loj hlob ntawm chlorinated roj hmab series ntawm anti-xeb txheej hloov.

Vim tias cov roj hmab chlorinated yog ib feem, kev tsim kho yog ib qho yooj yim, dej tsis kam, roj kuj, atmospheric aging kuj zoo heev, dav siv nyob rau hauv shipbuilding, industrial xeb tiv thaiv thiab lwm yam teb, muaj ib tug dav kev lag luam nyob rau hauv Tuam Tshoj. Txawm li cas los xij, vim tias kev tsim cov roj hmab chlorinated siv CC1 ua cov kuab tshuaj, cov txheej txheej ozone raug rhuav tshem.

Qhov thib yim yog kev txhim kho cov organic hloov kho inorganic xeb tiv thaiv cov ntaub ntawv.

Nyob rau hauv xyoo tas los no, daim ntawv thov ntawm cov organic emulsion hloov ua vaj tse los txhim kho nws lub zog, nruab nrab kuj, dav siv nyob rau hauv industrial pem teb txheej. Ntawm lawv, epoxy dej emulsion (los yog hnyav-raws li epoxy) yog tsim kom ceev tshaj plaws, uas yog hu ua polymer cement.
