Heerka cilmi baarista samaynta daahan Dacromet-la'aanta ah ee guriga

La dhajiyay 2019-02-12Silikoonka iyo budada nano-budada ee lagu daweeyay nano-kala-firdhinta ayaa loo kala firdhiyaa tiro badan oo ah resin-ku-xiran-xariifeedka polymerized resins-ka, ka dib marka la beddelo, budada zinc iyo budada aluminiumka ayaa la heli karaa si ay u yeeshaan chromium-free, acid- adkaysi, iyo Magnesium daawaha chromium-free Dacromet leh faa'iidooyinka iska caabin ah buufin milix, ilaalinta deegaanka, filimka daahan khafiif ah, iska caabin cimilada wanaagsan iyo iska caabin saamaynta.Zhang Shuyong iyo al.budada zinc lagu daray, budada aluminium, biyo deionized, kala firdhiyey (decadiol polyoxyethylene ether ama cetyl polyoxyethylene ether), phosphate (aluminium hydroxide iyo 85% phosphoric acid ee saamiga), Thickener (biyo-milmi methyl cellulose ether ama hydroxypropyl methyl cellulose ether sodium), Tripolyphosphate, polymerization initiator (35% hydrogen peroxide iyo / ama potassium permanganate), nidaamiyaha pH (zinc oxide, oxidation Calcium ama calcium hydroxide) iyo gargaarka filimaanta (polyetylene glycol) ayaa lagu qasi karaa si waafaqsan saamiga qaarkood, si siman loo walaaqay, pH waa lagu xakameynayo 3.5 ilaa 5.5 si loo helo dareeraha daahan ee chromium-free.Hal-abuurku waa mid deegaan ahaan u wanaagsan oo aan wasakhayn.Waxqabadka daxalka ayaa 7 ilaa 10 jeer ka sarreeya kan elektaroonigga ah, sidoo kale wuxuu leeyahay faa'iidooyinka qulqulka sarreeya, hoos u dhigista khilaafka sare, iyo iska caabinta cimilada sare.Zhu Chengfei iyo al.Budada Zinc, budada aluminium, qoynta iyo kala firdhinta (khamriga ama khamriga), wakiilka passivating (phytic acid), daxalka inhibitor (sodium molybdate), biyaha, wakiilka samaynta filim (manganese acetate, manganese nitrate ama Manganese chloride), gargaarka filim (silane). wakiilka isku xidhka), samaynta gargaarka (boric acid ama succinic acid) iyo dhumucdiisuna (hydroxymethyl cellulose ama hydroxyethyl cellulose) waxaa loo diyaariyey si waafaqsan saamiga qaar ka mid ah si ay u helaan ma marka la barbar dhigo farshaxanka hore, dareeraha daahan chromium dacrox leeyahay faa'iidooyinka wasakh lahayn, wasakh la'aan, isticmaalka tamarta yar iyo iska caabbinta xirashada wanaagsan.
Isticmaalka phosphoric acid sida binder iyo wakiilka passivating, dhul dhif ah waa caawiye, budada aluminium, budada zinc, 85% phosphoric acid, aluminium hydroxide, hydrogen peroxide, calcium oxide, cetyl polyoxyethylene ether, hydroxypropyl cellulose ether , ammonium cerium nitrate iyo ammonium nitrate waa isku dhafan. marka loo eego saami gaar ah, oo si siman loo walaaqay, pH-na waxaa lagu koontaroolaa 5.5, si loo helo dareere daahan oo aan chromium-free ah oo leh iska caabin daxaleed aad u wanaagsan.Cilmi baaristu waxay muujineysaa in ku darida milixda strontium ee naadir ah ay si wax ku ool ah u yareyso dahaarka.Xakamaynta daxalka ee lakabka ayaa leh saameyn wanaagsan oo ka hortag ah oo ku saabsan daaha Dacromet.
