Utoto woletsa dzimbiri

Utoto woletsa dzimbiri ndi mtundu wa chinthu chomwe chimagwira ntchito yoletsa dzimbiri, chimaletsa dzimbiri lachitsulo komanso chimathandizira kuti filimu ya utoto itetezeke pamwamba pa chitsulo. Ntchito ya utoto woletsa dzimbiri ingagawidwe m'magulu awiri: woletsa dzimbiri lakuthupi ndi woletsa dzimbiri la mankhwala, pomwe utoto woletsa dzimbiri wa mankhwala ungagawidwe m'magulu awiri: woletsa dzimbiri lakuthupi ndi woletsa dzimbiri la mankhwala amtundu wachiwiri. Zinthu zomwe zimagwira ntchito yoletsa dzimbiri zimaphatikizapo ufa wofiira wa pinki, ufa wofiira wachitsulo, ufa wa titaniyamu wachitsulo wophatikizika, ufa wa zinki wa aluminiyamu tripolyphosphate ndi zina zotero. Pakadali pano, utoto woletsa dzimbiri umagwiritsidwa ntchito kwambiri popanga zokutira zoletsa dzimbiri, ndipo mtengo wa zokutira zoletsa dzimbiri ndi 6%-8.5%.

Kodi kusiyana pakati pa utoto woletsa dzimbiri ndi utoto ndi kotani?

Utoto woletsa dzimbiri ndi mtundu wa utoto womwe ungateteze pamwamba pa zitsulo ku dzimbiri la mankhwala kapena lamagetsi lomwe limabwera chifukwa cha mlengalenga, madzi a m'nyanja, ndi zina zotero. Utoto woletsa dzimbiri monga chitsulo chofiira, ufa wa aluminiyamu, utoto woletsa dzimbiri wa graphite, lead wofiira, utoto wachikasu wa zinc woletsa dzimbiri ndi zina zotero.

Utoto ndi utoto wosakaniza mankhwala womwe umaphimba mwamphamvu pamwamba pa zinthu, kuteteza, kukongoletsa, kulemba ndi ntchito zina zapadera, ndikupanga filimu yolimba yomwe imamatira mwamphamvu pamwamba pa zinthu ndipo imakhala ndi mphamvu inayake komanso yopitilira.

1. Ntchito zosiyanasiyana:

Utoto woletsa dzimbiri uli ndi mphamvu zoletsa dzimbiri komanso zoletsa dzimbiri, filimuyo ndi yolimba, imagwira ntchito bwino kwambiri, ndipo kuuma kwake ndi kwakukulu kuposa utoto wamba. Utoto wamba ulibe ntchito yoletsa dzimbiri, chifukwa utoto wamba ndi alkyd resin, kudzera mu okosijeni ndi kuuma, kuuma koyipa, komanso kusiyana kwa ma grade adhesion.

2. Moyo wosiyanasiyana wautumiki:

Utoto woletsa dzimbiri ungagwiritsidwe ntchito kwa zaka 5-8 ngati ukugwirizana. Utoto wamba nthawi zambiri umagwiritsidwa ntchito panja kwa zaka pafupifupi 3. Pakatha zaka ziwiri kapena zitatu, umatha kugwa, kufota ndi kupunduka.

3. Mitundu yosiyanasiyana:

Utoto woletsa dzimbiri: utoto woletsa dzimbiri wa phenolic, utoto woletsa dzimbiri wa alkyd (wofiira wachitsulo, imvi, utoto wofiira), utoto woletsa dzimbiri wa rabara wothira chlorinated, utoto wa epoxy woletsa dzimbiri (utoto woletsa dzimbiri wa zinc phosphate, utoto wofiira woletsa dzimbiri, utoto woletsa dzimbiri wa zinc wambiri, utoto wofiira wachitsulo woletsa dzimbiri), ndi zina zotero.

Utoto: Utoto wolemera, utoto wotsutsana ndi dzimbiri ndi mtundu wa utoto, kuwonjezera pa utotowo umaphatikizaponso utoto wamatabwa, utoto wapansi, utoto wakunja kwa khoma, utoto wamwala, utoto wamitundu yambiri, utoto wa aluminiyamu, utoto wosapsa ndi moto, utoto wa latex ndi zina zotero.

Malangizo asanu ndi atatu a chitukuko cha utoto wotsutsana ndi dzimbiri mtsogolo

Choyamba, kupanga pulasitala woteteza dzimbiri wopangidwa ndi madzi komanso utoto wapamwamba wa nyumba zachitsulo.

Choyambira choteteza dzimbiri chochokera m'madzi chiyenera kuthetsa kukhumudwa kwa "dzimbiri la flash" la substrate ndi kukana madzi koipa, ndipo kukwera kwa ma emulsions atsopano opanda emulsifier kwasintha kwambiri dzina lake losavomerezeka ndi madzi, ndipo tsogolo liyenera kuyang'ana kwambiri kuthetsa mavuto a ntchito yomanga ndi ntchito yogwiritsira ntchito. Monga topcoat, cholinga chake chachikulu ndi kukonza kukongoletsa kwake ndi kulimba kwake poonetsetsa kuti ntchito yoteteza ikugwira ntchito.

Chachiwiri ndikupanga utoto wochuluka wolimba komanso woletsa dzimbiri wopanda zosungunulira.

Kubowola, nsanja za m'mphepete mwa nyanja ndi mapulojekiti akuluakulu oletsa dzimbiri mu ntchito yolimbana ndi dzimbiri yolimba kwambiri ya zofunikira pakuphimba ndizofunikira kwambiri, msika wamakono uli ndi makampani akunja ndi zinthu zochokera kunja zomwe zimagwidwa. Zogulitsa zaku China zili makamaka pamlingo waukadaulo, mphamvu zachuma, dongosolo lotsimikizira khalidwe ndi mbiri ya malonda ndi kusiyana kwina kwamphamvu ndi mayiko akunja, n'kovuta kulowa mumsika. Pachifukwa ichi, choyamba, kuyesetsa kuyenera kupangidwa pakukonza ukadaulo, makamaka kupanga primer yopanda lead komanso yopanda chromium yoletsa dzimbiri, ndiko kuti, yochokera ku zinc phosphate ndi aluminium tripolyphosphate yoletsa dzimbiri.

Chachitatu ndi kupanga pulasitala wokhala ndi zinc wambiri m'madzi.

Choyambira chopanda zinki ndi chopanda zinki ndi chimodzi mwa zoyambira zomwe zimagwira ntchito nthawi yayitali, koma ndi zophimba zosungunuka. Choyambira chopanda zinki ndi chopanda zinki chokhala ndi modulus potassium silicate yambiri ngati maziko ake ndi chophimba cholimba choteteza dzimbiri chomwe chimayesedwa ndi machitidwe ndipo chili ndi kuthekera kopanga.

Chachinayi ndi chitukuko cha chosinthira kutentha chomwe chimachiritsa kutentha cholimbana ndi dzimbiri.

Zosinthira kutentha zimafuna zophimba zotsutsana ndi dzimbiri zomwe zimalimbana ndi kutentha kwambiri komanso kutentha kwambiri, ndipo zophimba za epoxy amino zomwe zikugwiritsidwa ntchito pano ziyenera kutsukidwa pa 120 ° C ndipo zimafuna zophimba zingapo, zomwe sizingagwiritsidwe ntchito pazida zazikulu.

Chachisanu ndi kupanga chophimba chomwe chingachiritsidwe kutentha kwa chipinda ndipo n'chosavuta kugwiritsa ntchito.

Mfundo yofunika kwambiri ndikupeza mgwirizano wabwino pakati pa ntchito yoteteza dzimbiri, ntchito yosamutsa kutentha ndi ntchito yomanga ya chophimbacho.

Chachisanu ndi chimodzi ndi chitukuko cha utoto wotsutsana ndi dzimbiri.

Mica iron oxide (MIO) ili ndi mphamvu yabwino kwambiri yolimbana ndi dielectric, kukana kukalamba mumlengalenga komanso ntchito yoletsa, ndipo imagwiritsidwa ntchito kwambiri ngati utoto woyambira komanso wapamwamba ku Western Europe.

Chachisanu ndi chiwiri, kupanga mitundu yosiyanasiyana ya mphira wothira chlorine womwe umalowa m'malo mwa utoto wotsutsana ndi dzimbiri.

Popeza mphira wothira chlorine ndi chinthu chimodzi, kapangidwe kake ndi kosavuta, kukana madzi, kukana mafuta, kukana kukalamba mumlengalenga ndikwabwino kwambiri, kumagwiritsidwa ntchito kwambiri popanga zombo, kupewa dzimbiri m'mafakitale ndi madera ena, pali msika waukulu ku China. Komabe, chifukwa kupanga mphira wothira chlorine kumagwiritsa ntchito CC1 ngati chosungunulira, ozoni wosanjikiza umawonongeka.

Chachisanu ndi chitatu ndi chitukuko cha zipangizo zopewera dzimbiri zosagwiritsidwa ntchito m'chilengedwe.

M'zaka zaposachedwapa, kugwiritsa ntchito konkire ya organic emulsion kwasintha mphamvu yake, kukana kwapakati, komwe kumagwiritsidwa ntchito kwambiri popanga zokutira pansi zamafakitale. Pakati pawo, emulsion yamadzi ya epoxy (kapena epoxy yochokera ku solvent) ikupanga yothamanga kwambiri, yotchedwa simenti ya polymer.

Zambiri zaife

Kampani yathunthawi zonse wakhala akutsatira "sayansi ndi ukadaulo, khalidwe loyamba, kuona mtima komanso kudalirika, kukhazikitsa malamulo okhwima a ls0900l:.2000 dongosolo lapadziko lonse lapansi loyang'anira khalidwe. Kasamalidwe kathu kolimba, luso lathu lopanga zinthu zabwino, lapambana kudziwika kwa ogwiritsa ntchito ambiri.Monga katswiri fakitale yokhazikika komanso yolimba yaku China, titha kupereka zitsanzo kwa makasitomala omwe akufuna kugula, ngati mukufuna utoto woletsa dzimbiri, chonde titumizireni.
