Utoto wotsutsa dzimbiri

Utoto wotsutsa dzimbiri ndi mtundu wazinthu zomwe zimagwira ntchito yodana ndi dzimbiri, zimalepheretsa dzimbiri zachitsulo ndikuwongolera chitetezo cha filimu ya utoto pazitsulo. Udindo wa utoto wotsutsa dzimbiri ukhoza kugawidwa m'magulu awiri: odana ndi dzimbiri ndi mankhwala odana ndi dzimbiri, omwe utoto wa mankhwala odana ndi dzimbiri ukhoza kugawidwa muzoletsa zowonongeka ndi electrochemical action mtundu wachiwiri. Zinthu zomwe zimagwira ntchito yoletsa dzimbiri zimaphatikizapo ufa wofiira wa pinki, ufa wofiira wachitsulo, ufa wa titaniyamu wachitsulo, aluminium tripolyphosphate zinc ufa ndi zina zotero. Pakalipano, utoto wotsutsa-dzimbiri umagwiritsidwa ntchito makamaka mu zokutira zotsutsana ndi dzimbiri, ndipo mtengo wa anti-corrosion wokutira ndi 6% -8.5%.

Kodi pali kusiyana kotani pakati pa Anti-dzimbiri penti ndi utoto?

Utoto wa antirust ndi mtundu wa utoto womwe ungatetezere zitsulo kuchokera ku mankhwala kapena electrochemical corrosion of atmosphere, madzi a m'nyanja, etc. Utoto wakuthupi ndi mankhwala odana ndi dzimbiri, monga chitsulo chofiira, aluminium ufa, graphite anti- dzimbiri utoto, kutsogolera kofiira, zinc yellow anti- dzimbiri utoto ndi zina zotero.

Utoto ndi mankhwala osakaniza ❖ kuyanika kuti mwamphamvu chimakwirira pamwamba pa zinthu, amateteza, amakongoletsa, zizindikiro ndi zolinga zina zapadera, ndi kupanga filimu olimba amene amamatira molimba pamwamba pa zinthu ndipo ali ndi mphamvu inayake ndi kupitiriza.

1. Ntchito zosiyanasiyana:

Utoto wotsutsana ndi dzimbiri uli ndi zotsutsana ndi dzimbiri komanso zotsutsana ndi dzimbiri, filimuyo ndi yolimba, yochita bwino kwambiri, ndipo kuuma kwake ndikwapamwamba kuposa utoto wamba. utoto wamba alibe ntchito odana ndi dzimbiri, chifukwa wamba utoto filimu zakuthupi ndi alkyd utomoni, kudzera makutidwe ndi okosijeni ndi kuyanika, osauka kuuma, adhesion kalasi kusiyana.

2. Moyo wautumiki wosiyanasiyana:

Utoto wotsutsana ndi dzimbiri ungagwiritsidwe ntchito kwa zaka 5-8 ngati mukufanana. Utoto wamba nthawi zambiri umagwiritsidwa ntchito panja pafupifupi zaka zitatu. Pambuyo pa zaka ziwiri kapena zitatu, zimakhala zosavuta kugwa, kuzimiririka ndi ufa.

3. Mitundu yosiyanasiyana:

Utoto woletsa dzimbiri: utoto wa phenolic anti- dzimbiri, utoto wa alkyd woletsa dzimbiri (chitsulo chofiyira, chotuwa, chofiyira), utoto wa mphira wothira dzimbiri, utoto wa epoxy anti- dzimbiri (penti ya zinc phosphate anti- dzimbiri, utoto wofiira wotsutsa dzimbiri, utoto wonyezimira wa zinki, utoto wonyezimira wa chitsulo), ndi zina zotero.

Utoto: Mitundu yochuluka ya utoto, utoto wotsutsa dzimbiri ndi mtundu wa utoto, kuwonjezera pa utotowo umaphatikizansopo utoto wamatabwa, utoto wapansi, utoto wakunja wapakhoma, utoto wamwala, utoto wamitundu yambiri, utoto wa aluminiyamu, utoto wosayaka moto, utoto wa latex ndi zina zotero.

Njira zisanu ndi zitatu za chitukuko chamtsogolo cha utoto wotsutsa dzimbiri

Choyamba, chitukuko cha madzi opangira dzimbiri choyambirira ndi utoto wapamwamba wazitsulo zazitsulo.

Madzi oyambira odana ndi dzimbiri amayenera kuthana ndi kukhumudwa kwa gawo lapansi "flash dzimbiri" komanso kusakanizidwa bwino kwa madzi, komanso kukwera kwa emulsion yaulere ya emulsifier kwasintha kwambiri mutu wake wosakanizidwa ndi madzi, ndipo tsogolo liyenera kuyang'ana kwambiri kuthetsa mavuto a ntchito yomanga ndi ntchito yogwiritsira ntchito. Monga topcoat, makamaka kukonzanso kukongoletsa kwake ndi kulimba pansi pa chikhalidwe choonetsetsa kuti chitetezo chikugwira ntchito.

Chachiwiri ndikupanga mndandanda wazinthu zolimba kwambiri komanso utoto wopanda dzimbiri wopanda zosungunulira.

Kubowola, nsanja za m'mphepete mwa nyanja ndi ntchito zazikulu zotsutsana ndi dzimbiri mu ntchito yolimbana ndi dzimbiri yokhazikika pazofunikira zopaka ndizofunikira kwambiri, msika wapano ndi mabizinesi akunja ndi zinthu zomwe zimatumizidwa kunja. mankhwala China ali makamaka mu mlingo luso, mphamvu zachuma, dongosolo chitsimikizo khalidwe ndi mbiri mankhwala ndi ena mabuku mphamvu kusiyana ndi mayiko akunja, n'zovuta kulowa msika. Kuti izi zitheke, choyamba, kuyesetsa kuyenera kupangidwa pakukula kwaukadaulo, makamaka kukulitsa koyambirira kwa pigment ya pigment yopanda kutsogolera komanso yopanda chromium, ndiye kuti, yochokera pazinc phosphate ndi aluminium tripolyphosphate anti- dzimbiri primer.

Chachitatu ndi kupanga zoyambira zam'madzi zokhala ndi zinc.

Zoyambira zokhala ndi zinc zambiri komanso zoyambira zam'madzi zokhala ndi zinc ndi imodzi mwazinthu zoyambira nthawi yayitali, koma ndi zokutira zosungunulira. Madzi opangidwa ndi zinc olemera kwambiri amadzi okhala ndi modulus potassium silicate monga maziko ake ndi anti- dzimbiri zokutira zoyesedwa ndi machitidwe ndipo zimakhala ndi chitukuko.

Chachinayi ndi chitukuko cha kutentha exchanger kuchiritsa kutentha kugonjetsedwa ndi dzimbiri zokutira.

Kutentha kwa kutentha kumafunikira zokutira zotsutsana ndi dzimbiri zokhala ndi kutentha kwakukulu komanso kutentha kwa kutentha, ndipo kupaka kwa epoxy amino komwe kumagwiritsidwa ntchito kumayenera kuchiritsidwa pa 120 ° C ndipo kumafuna zokutira zingapo, zomwe sizingagwiritsidwe ntchito pazida zazikulu.

Chachisanu ndi kupanga zokutira zomwe zingathe kuchiritsidwa kutentha kwa firiji komanso zosavuta kuziyika.

Mfundo yofunika kwambiri ndiyo kupeza bwino pakati pa ntchito yoletsa dzimbiri, ntchito yotumizira kutentha ndi ntchito yomanga ya zokutira.

Chachisanu ndi chimodzi ndikukula kwa flake anti- dzimbiri zokutira.

Mica iron oxide (MIO) ili ndi kukana kwa dielectric, kukana kukalamba kwamlengalenga ndi kutsekereza ntchito, ndipo imagwiritsidwa ntchito kwambiri ngati penti yoyambira komanso yapamwamba ku Western Europe.

Chachisanu ndi chiwiri, chitukuko cha mphira wothira m'malo odana ndi dzimbiri.

Chifukwa mphira wa chlorinated ndi gawo limodzi, kumangako ndikosavuta, kukana madzi, kukana mafuta, kukana kukalamba kwamlengalenga ndikwabwino, komwe kumagwiritsidwa ntchito popanga zombo, kupewa dzimbiri m'mafakitale ndi madera ena, pali msika wotakata ku China. Komabe, chifukwa kupanga mphira wa chlorine kumagwiritsa ntchito CC1 monga zosungunulira, ozoni wosanjikiza amawonongeka.

Chachisanu ndi chitatu ndi chitukuko cha organic kusinthidwa inorganic zipangizo kupewa dzimbiri.

M'zaka zaposachedwapa, ntchito organic emulsion kusinthidwa konkire kusintha mphamvu zake, kukana sing'anga, chimagwiritsidwa ntchito mu ❖ kuyanika mafakitale pansi. Pakati pawo, epoxy madzi emulsion (kapena zosungunulira-based epoxy) akupanga yachangu, amene amatchedwa polima simenti.
