Kau ʻia ma 2019-02-12ʻO ka silicone a me ka nano-powder i mālama ʻia me ka nano-dispersion ua hoʻopuehu ʻia i loko o kahi plurality o resin cross-linked polymerized composite resins, a ma hope o ka hoʻololi ʻia, hiki ke loaʻa ka pauka zinc a me ka pauka alumini i loaʻa ka chromium-free, acid- kū'ē, a me Magnesium alloy chromium-free Dacromet solution me nā mea maikaʻi o ka pale ʻana i ka paʻakai, ka mālama ʻana i ke kaiapuni, ke kiʻi ʻoniʻoni ʻoniʻoni, ke kūpaʻa maikaʻi o ka wā a me ke kūpaʻa hopena.ʻO Zhang Shuyong et al.ua hoʻohui ʻia ka pauka zinc, ka pauka alumini, ka wai deionized, ka dispersant (decadiol polyoxyethylene ether a i ʻole cetyl polyoxyethylene ether), phosphate (aluminum hydroxide a me 85% phosphoric acid i ka like), Thickener (wai-soluble methyl cellulose ether a i ʻole hydroxypropyl methyl cellulose ether), sodium tripolyphosphate, polymerization initiator (35% hydrogen peroxide a me / a i ʻole potassium permanganate), pH regulator (zinc oxide, oxidation Calcium a calcium hydroxide) a me ke kōkua kiʻiʻoniʻoni (polyethylene glycol) ua hui pū ʻia e like me kahi ratio, hoʻoulu like ʻia, a ʻo ka pH hoʻomalu ʻia ma 3.5 a 5.5 no ka loaʻa ʻana o kahi wai uhi Dacromet chromium-free.He pili kaiapuni ka mea i hanaia a me ka pollution-free.ʻO ka hana corrosion ʻo 7 a 10 mau manawa kiʻekiʻe ma mua o ka electrogalvanized, a loaʻa iā ia nā pono o ka permeability kiʻekiʻe, ka hoʻohaʻahaʻa haʻahaʻa kiʻekiʻe, a me ke kūpaʻa kiʻekiʻe.ʻO Zhu Chengfei et al.ʻO ka pauka Zinc, ka pauka alumini, ka mea hoʻoheheʻe a me ka dispersing agent (ka waiʻona a i ʻole polyalcohol), ka mea passivating (phytic acid), ka corrosion inhibitor (sodium molybdate), ka wai, ka mea hana kiʻiʻoniʻoni (manganese acetate, manganese nitrate a i ʻole Manganese chloride), kōkua kiʻi (silane). Hoʻopili ʻia ka mea hoʻohui), hoʻokumu i ke kōkua (boric acid a succinic acid) a me ka mānoanoa (hydroxymethyl cellulose a i ʻole hydroxyethyl cellulose) i hoʻomākaukau ʻia e like me kahi lakene e loaʻa ʻole ai Ke hoʻohālikelike ʻia me ka hana mua, ʻo ka chromium dacrox coating wai ka maikaʻi o ka pollution. ʻaʻohe haumia, hoʻohana haʻahaʻa haʻahaʻa a me ke kūpaʻa ʻaʻahu maikaʻi.
Ke hoʻohana nei i ka waikawa phosphoric e like me ka mea hoʻopaʻa a me ka passivating agent, he mea kōkua ka honua laʻa, ka pauka alumini, ka pauka zinc, 85% phosphoric acid, alumini hydroxide, hydrogen peroxide, calcium oxide, cetyl polyoxyethylene ether, hydroxypropyl cellulose ether, ammonium cerium nitrate a me ammonium nitrate. e like me kekahi lākiō, hoʻoulu ʻia, a mālama ʻia ka pH i ka 5.5, e loaʻa ai kahi chromium-free Dacromet coating wai me ke kūpaʻa maikaʻi loa.Hōʻike ka noiʻi ʻana i ka hoʻohui ʻana o ka paʻakai strontium honua hikiʻole ke hōʻemi i ka uhi.Loaʻa ka hopena corrosion inhibition maikaʻi ma ka uhi ʻana o Dacromet.
