Ubume bophando lwe-chromium-free Dacromet yokwenziwa kokwambathisa

Iposwe kwi 2019-02-12I-silicone kunye ne-nano-powder ephathwa nge-nano-dispersion iyahlakazeka ibe yininzi ye-resin cross-linked polymerized composite resins, kwaye emva kokuguqulwa, i-zinc powder kunye ne-aluminium powder inokufumaneka ukuba ibe ne-chromium-free, i-asidi- ukumelana, kunye ne-Magnesium alloy chromium-free Dacromet solution kunye nezibonelelo zokuxhathisa ityuwa yokutshiza, ukukhuselwa kwendalo, ifilimu enqabileyo yokugquma, ukumelana nemozulu elungileyo kunye nokuchasana kwempembelelo.UZhang Shuyong et al.i-zinc powder, i-aluminium powder, amanzi adibeneyo, i-disperant (i-decadiol polyoxyethylene ether okanye i-cetyl polyoxyethylene ether), i-phosphate (i-aluminium hydroxide kunye ne-85% ye-phosphoric acid ngokomlinganiselo), i-Thickener (i-soluble methyl cellulose ether okanye i-hydroxypropyl cellulose sodium) i-tripolyphosphate, i-polymerization initiator (i-35% ye-hydrogen peroxide kunye / okanye i-potassium permanganate), isilawuli se-pH (i-zinc oxide, i-oxidation I-Calcium okanye i-calcium hydroxide) kunye noncedo lokufowuna (i-polyethylene glycol) zixutywe ngokomlinganiselo othile, zixutywe ngokulinganayo, kunye ne-pH. kulawulwa kwi-3.5 ukuya ku-5.5 ukufumana i-chromium-free Dacromet yokwambathisa ulwelo.Ukwenziwa kwayo kuhambelana nokusingqongileyo kwaye akungcoliseki.Ukusebenza kwe-corrosion ku-7 ukuya kwi-10 ngaphezulu kwamaxesha e-electrogalvanized, kwaye ikwanenzuzo yokungena okuphezulu, ukucutha i-friction ephezulu, kunye nokumelana nemozulu ephezulu.UZhu Chengfei et al.I-zinc powder, umgubo we-aluminium, i-agent yokumanzisa kunye ne-dispersing agent (utywala okanye i-polyalcohol), i-agent edlulayo (i-phytic acid), i-corrosion inhibitor (i-sodium molybdate), amanzi, i-agent eyenza ifilimu (i-manganese acetate, i-manganese nitrate okanye i-Manganese chloride), uncedo lokufota (i-silane). i-arhente yokudibanisa), i-aid yokwenza (i-boric acid okanye i-succinic acid) kunye ne-thickener (i-hydroxymethyl cellulose okanye i-hydroxyethyl cellulose) zilungiswa ngokomlinganiselo othile wokufumana akukho Xa kuthelekiswa nobugcisa bangaphambili, ulwelo lokugquma i-chromium dacrox lunoncedo lokungangcoliseki, akukho ngcoliseko, ukusetyenziswa kwamandla aphantsi kunye nokumelana nokunxiba kakuhle.
Ukusebenzisa i-asidi ye-phosphoric njenge-binder kunye ne-passivating agent, umhlaba onqabileyo uncedisayo, i-aluminium powder, i-zinc powder, i-85% ye-phosphoric acid, i-aluminium hydroxide, i-hydrogen peroxide, i-calcium oxide, i-cetyl polyoxyethylene ether, i-hydroxypropyl cellulose ether, i-ammonium cerium nitrate kunye ne-ammonium nitrate exutyiweyo. ngokomlinganiselo othile, ivuselelwe ngokulinganayo, kwaye pH ilawulwa ukuya ku-5.5, ukufumana i-chromium-free Dacromet yokugquma ulwelo kunye nokumelana nokugqwesa okugqwesileyo.Uphando lubonisa ukuba ukongezwa kwetyuwa yomhlaba enqabileyo ye-strontium kunciphisa ngokufanelekileyo ukugquma.I-corrosion current of the layer ine-corrosion inhibition effect kwi-coating ye-Dacromet.
