Metsi a Thehiloeng Aluminium Peista | Aluminium Pigment
Tlhaloso:
Aluminium Paste, ke pigment ea bohlokoa ea tšepe. Likarolo tsa eona tse ka sehloohong ke likaroloana tsa aluminium tsa lehloa le li-solvents tsa petroleum ka mokhoa oa peista. Ke ka mor'a theknoloji e khethehileng ea ts'ebetso le phekolo ea holim'a metsi, ho etsa hore bokaholimo ba aluminium bo boreleli le bohale bo bataletseng bo be makhethe, sebopeho se tloaelehileng, mahloriso a boholo ba likaroloana, le ho tsamaisana hantle le mokhoa oa ho roala. Aluminium peista e ka aroloa ka mekhahlelo e 'meli: leafing mofuta le bao e seng leafing. Nakong ea ts'ebetso ea ho sila, acid e 'ngoe ea mafura e nkeloa sebaka ke e' ngoe, e leng se etsang hore Aluminium Paste e be le litšobotsi tse fapaneng ka ho feletseng le ponahalo, 'me libopeho tsa li-flakes tsa aluminium ke lehloa la lehloa, tekanyo ea tlhapi le dollar ea silevera. Haholo-holo e sebelisoa ka liphahlo tsa likoloi, liphahlo tsa polasetiki tse fokolang, liphahlo tsa liindasteri tsa tšepe, liaparo tsa leoatleng, liaparo tse thibelang mocheso, liphahlo tsa marulelo joalo-joalo. E boetse e sebelisoa ka pente ea polasetiki, hardware le pente ea lisebelisoa tsa lapeng, pente ea sethuthuthu, pente ea libaesekele joalo-joalo.
Litšobotsi:
Water Based Aluminium Pigment, eo hape e tsejoang e le aqueous aluminium peste, e ntlafalitsoeng ka nts'etsopele ea liphahlo tse nang le metsi. Aluminium ke ntho e mahlahahlaha ea tšepe ea amphoteric mme e sebetsa habonolo ka metsi, asiti le alkali. E lokela ho nka phekolo e khethehileng ea holim'a metsi ha e kenngoa tsamaisong ea metsi a resin. Har'a 'maraka mekhoa ea pente ea aluminium e nang le metsi e ka aroloa ka mekhahlelo e 4:
1 Eketsa corrosion inhibitor; 2 Chromic acid kapa chromate passivation; 3 Mokhoa oa ho roala silika; 4 Mokhoa oa marang-rang oa Inorganic le oa organic o koahetsoeng habeli kapa o kenang lipakeng (IPN). Mekhoa ena e na le melemo le mathata a fapaneng. Hammoho le litlhoko tse phahameng tsa ts'ireletso ea tikoloho, mekhoa e 'meli ea ho qetela e tla sebelisoa le ho feta.
Kopo:
Sekhabiso sa aluminium se nang le metsi se sebelisoa haholo ka liphahlo tsa likoloi tse nang le metsi, thepa ea ka tlung le lipente tse ling tse khabisitsoeng, litlolo, liphutheloana tsa lijo, letlalo le masela, lipapali tsa bana, joalo-joalo.

Tataiso ea Kopo:
1.Foam slurry tse 'maloa ,inures hamorao, susumetsang maikutlo butle le eketsa aqueous coatings emulsion, ka eketsa ba bang ba dispersant ka tsela e loketseng ho qoba lesihla le phatsa pula.
2.U se ke ua e tsosoa ka lebelo le phahameng, haeba matla a phahameng a ho kuta a senya ho roala ha aluminium pigment; lebelo le potolohang le lokela ho laola ka 300-800rpm.
3.Bakeng sa liphetho tse ntle, o lokela ho sefa hantle ho roala ha metsi.
4.Ka polokelo ea nako e telele, pente ea aluminium e ka hlahisa likaroloana. U ka e kenya ka metsi a hloekileng kapa glycol ether metsotso e 'maloa, e sisinyehe hanyenyane ebe e tla hlaha.
5.Storage: Qoba letsatsi le tobileng; ka mor'a ho sebelisa pente ea aluminium, koala sekoahelo sa meropa haufinyane.
Lintlha:
1. Ka kopo etsa bonnete ba hore u netefatsa sampuli pele ho tšebeliso e 'ngoe le e' ngoe ea pente ea silevera ea aluminium.
2. Ha u qhala sekontiri sa aluminium-silevera, sebelisa mokhoa oa pre-dispersing: khetha solvent e loketseng pele, kenya motsoako ka har'a pente ea aluminium-silevera ka karo-karolelano ea aluminium-silevera pente ho solvent e le 1: 1-2, e tsose. butle-butle le ka mokhoa o ts'oanang, ebe oe tšela ka har'a thepa e lokiselitsoeng ea motheo.
3. Qoba ho sebelisa lisebelisoa tsa ho qhala ka lebelo le phahameng ka nako e telele nakong ea ho kopanya.
Litaelo tsa polokelo:
1. Sekhahla sa silevera sa aluminium se lokela ho boloka setshelo se tiisitsoe mme mocheso oa polokelo o lokela ho bolokoa ho 15 ℃ ~ 35 ℃.
2. Qoba ho pepesehela letsatsi le tobileng, pula le mocheso o feteletseng.
3. Ka mor'a ho koala, haeba ho na le pente e setseng ea silevera ea aluminium e lokela ho tiisoa hang-hang ho qoba ho fetoha mouoane oa solvent le ho hlōleha ha oxidation.
4. Ho boloka nako e telele ea pente ea silevera ea aluminium e ka 'na ea e-ba ho feto-fetoha ha solvent kapa tšilafalo e' ngoe, ka kopo hlahloba hape pele u sebelisoa ho qoba tahlehelo.
Mehato ea tšohanyetso:
1. Tabeng ea mollo, ka kopo sebelisa phofo ea lik'hemik'hale kapa lehlabathe le khethehileng le omeletseng ho tima mollo, u se ke ua sebelisa metsi ho tima mollo.
2. Haeba pente ea silevera ea aluminium e ka kena ka mahlo ka phoso, ka kopo, hlatsoa ka metsi bonyane metsotso ea 15 'me u batle keletso ea bongaka.
