Kafukufuku wamapangidwe apanyumba opanda chromium a Dacromet

Adalemba pa 2019-02-12Silicone ndi nano-ufa wothiridwa ndi nano-kubalalitsidwa amamwazikana muunyinji wa utomoni wolumikizana ndi ma polymerized resins, ndipo atasinthidwa, ufa wa zinki ndi aluminiyamu ufa ukhoza kupezeka kuti ukhale wopanda chromium, acid- kugonjetsedwa, ndi Magnesium aloyi chromium-free Dacromet yankho ndi ubwino wa mchere kutsitsi kukana, kuteteza chilengedwe, woonda ❖ kuyanika filimu, zabwino nyengo kukana ndi kukana mphamvu.Zhang Shuyong et al.anawonjezera nthaka ufa, aluminiyamu ufa, deionized madzi, dispersant (decadiol polyoxyethylene ether kapena cetyl polyoxyethylene ether), phosphate (aluminium hydroxide ndi 85% phosphoric acid mu gawo), Thickener (madzi osungunuka methyl cellulose ether kapena hydroxypropyl sodium cellulose methyl cellulose), tripolyphosphate, polymerization initiator (35% hydrogen peroxide ndi / kapena potaziyamu permanganate), pH regulator (zinc oxide, oxidation Calcium kapena calcium hydroxide) ndi chithandizo chojambulira (polyethylene glycol) zimasakanizidwa molingana ndi chiŵerengero china, kugwedezeka mofanana, ndipo pH imayikidwa. yoyendetsedwa pa 3.5 mpaka 5.5 kuti mupeze madzi opaka a Dacromet opanda chromium.Zomwe zatulukirazi sizimawononga chilengedwe komanso siziwononga chilengedwe.Kuwonongeka kwa dzimbiri ndi 7 mpaka 10 kuwirikiza kawiri kuposa electrogalvanized, komanso kuli ndi ubwino wa permeability, kuchepetsa kukangana kwakukulu, komanso kukana kwa nyengo.Zhu Chengfei et al.Zinc ufa, aluminiyamu ufa, kunyowetsa ndi dispersing agent (mowa kapena polyalcohol), passivating agent (phytic acid), corrosion inhibitor (sodium molybdate), madzi, kupanga filimu (manganese acetate, manganese nitrate kapena manganese chloride), chothandizira kujambula (silane). coupling wothandizila), kupanga thandizo (boric acid kapena succinic acid) ndi thickener (hydroxymethyl cellulose kapena hydroxyethyl mapadi) amakonzedwa molingana ndi chiŵerengero kuti palibe Poyerekeza ndi luso m'mbuyomu, chromium dacrox ❖ kuyanika madzi ali ndi ubwino palibe kuipitsa, palibe kuipitsidwa, kugwiritsa ntchito mphamvu zochepa komanso kukana kuvala bwino.
Pogwiritsa ntchito phosphoric acid monga binder ndi passivating agent, dziko losowa ndilothandizira, ufa wa aluminiyamu, ufa wa zinki, 85% phosphoric acid, aluminium hydroxide, hydrogen peroxide, calcium oxide, cetyl polyoxyethylene ether, hydroxypropyl cellulose ether, ammonium cerium nitrate ndi ammonium nitrate ndi ammonium nitrate. molingana ndi chiŵerengero china, chogwedezeka mofanana, ndipo pH imayendetsedwa mpaka 5.5, kuti mupeze madzi opaka a Dacromet opanda chromium okhala ndi kukana kwa dzimbiri.Kafukufukuyu akuwonetsa kuti kuwonjezera mchere wosowa padziko lapansi wa strontium kumachepetsa kuyanika.Kutentha kwapang'onopang'ono kwa wosanjikiza kumakhala ndi zotsatira zabwino zoletsa kutukuta pa zokutira za Dacromet.
