I-Aluminiyam esekelwe emanzini iNcamathelo | I-Aluminiyam Pigment
Inkcazo:
I-Aluminiyam Paste, yinto eyimfuneko yepigment yentsimbi. Amacandelo ayo aphambili yi-snowflake aluminium particles kunye ne-petroleum solvents ngendlela yokunamathisela. Kungemva kwetekhnoloji yokulungiswa okukhethekileyo kunye nonyango lomphezulu, ukwenza umphezulu we-aluminium flake ugudileyo kunye nomphetho osicaba ucocekile, ukumila okuqhelekileyo, ukugxininiswa kobungakanani bamasuntswana, kunye nokuhambelana okugqwesileyo kunye nenkqubo yokwambathisa. I-Aluminiyam Paste inokohlulwa ibe ngamacandelo amabini: uhlobo lwamagqabi kunye nohlobo olungamagqabi. Ngexesha lokugaya, enye i-asidi enamafutha ithathelwa indawo yenye, eyenza i-Aluminiyam Paste ibe neempawu ezihluke ngokupheleleyo kunye nembonakalo, kwaye iimilo ze-aluminium flakes ziyi-snowflake, isikali seentlanzi kunye nedola yesilivere. Ikakhulu isetyenziswa kwiinqwelo zeemoto, iiplastiki ezibuthathaka, iingubo zentsimbi zemizi-mveliso, iingubo zaselwandle, iingubo ezichasene nobushushu, iingubo zokuphahla njalo njalo. Ikwasetyenziswa kwipeyinti yeplastiki, kwihardware nakwipeyinti yesixhobo sasekhaya, ipeyinti yesithuthuthu, ipeyinti yebhayisekile njalo njalo.
Iimpawu:
I-Water Based Aluminium Pigment, ekwabizwa ngokuba yintlama ye-aluminiyam enamanzi, iphuhliswe ngophuhliso lokwaleka kwamanzi. I-aluminiyam yinto edlamkileyo yesinyithi ye-amphoteric kwaye kulula ukusabela ngayo ngamanzi, iasidi kunye nealkali. Kufuneka kuthathe unyango olukhethekileyo lomphezulu xa ukongeza kwi-aqueous resin system. Phakathi kweemarike iindlela zokuncamathisela i-aluminiyam enamanzi zinokwahlulwa zibe ziindidi ezi-4:
1 Yongeza i-corrosion inhibitor; I-2 Chromic acid okanye i-chromate passivation; 3 indlela yokwaleka i-silica; 4 I-Inorganic kunye ne-organic coated kabini okanye i-interpenetrating networks method (IPN). Ezi ndlela zineenzuzo ezahlukeneyo kunye nokungonakali. Kanye kunye neemfuno eziphezulu zokukhuselwa kwendalo, iindlela ezimbini zokugqibela ziya kusetyenziswa ngakumbi nangaphezulu.
Isicelo:
I-aqueous aluminium paste isetyenziswa ngokubanzi kwiingubo zeemoto ezinamanzi, ifenitshala kunye nezinye iipeyinti zokuhombisa, izimonyo, ukupakishwa kokutya, ufele kunye nelaphu, amathoyizi abantwana, njl.

Isikhokelo seSicelo:
I-1.I-Foam slurry eziliqela, i-inures kamva, ivuselela ngokukhawuleza kwaye yongeze i-emulsion ye-aqueous coatings, inokongeza i-dispersant ngokufanelekileyo ukuphepha i-cluster kunye ne-particle precipitation.
2.Musa ukuyishukumisa ngesantya esiphezulu, xa kunokwenzeka ukuba i-shear force force itshabalalise i-pigment ye-aluminium; isantya esijikelezayo kufuneka silawule kwi-300-800rpm.
3.Ngeziphumo ezizezona zilungileyo, kufuneka ucoce ngcono i-aqueous coating.
4.Ngexesha elide lokugcina, i-aluminium yokunamathisela inokuvelisa amaqhekeza. Ungayithambisa ngamanzi acocekileyo okanye i-glycol ether imizuzu emininzi, uyishukumise kancinci kwaye emva koko iya kuvela.
5.Ukugcinwa: Kuphephe ukukhanya kwelanga; Emva kokusebenzisa intlama yealuminiyam, vala isigqubuthelo segubu kungekudala.
Amanqaku:
1. Nceda uqinisekise ukuba uqinisekise isampuli phambi kokusetyenziswa ngakunye kwe-aluminium yesilivere yokunamathisela.
2. Xa usasaza intlama ye-aluminium-silver, sebenzisa indlela yokusasaza kwangaphambili: khetha isinyibilikisi esifanelekileyo kuqala, yongeza isinyibilikisi kwintlama ye-aluminium-silver kunye nomlinganiselo we-aluminium-silver intlama kwi-solvent njenge-1: 1-2, yixube. kancinci kwaye ngokulinganayo, kwaye emva koko ugalele kwizinto ezisisiseko ezilungiselelwe.
3. Gwema ukusebenzisa izixhobo zokusasaza ngesantya esiphezulu ixesha elide ngexesha lokuxuba.
Imiyalelo yokugcina:
1. Intlama ye-aluminiyam yesilivere kufuneka igcine isikhongozeli sivaliwe kwaye ubushushu bokugcina kufuneka bugcinwe ku-15℃~35℃.
2. Kuphephe ukuchanabeka ngokuthe ngqo kwilanga elithe ngqo, imvula kunye nobushushu obugqithisileyo.
3. Emva kokungatywinwa, ukuba kukho nayiphi na intlama ye-aluminium yesilivere eseleyo kufuneka itywinwe ngokukhawuleza ukuphepha ukuqhuma kwe-solvent kunye nokusilela kwe-oxidation.
4. Ukugcinwa kwexesha elide le-aluminium yesilivere ye-paste ingaba yi-solvent volatility okanye enye ungcoliseko, nceda uphinde uvavanye ngaphambi kokusetyenziswa ukuze ugweme ilahleko.
Amanyathelo kaxakeka:
1. Kwimeko yomlilo, nceda usebenzise umgubo wekhemikhali okanye isanti ekhethekileyo eyomileyo ukucima umlilo, ungasebenzisi amanzi ukucima umlilo.
2. Ukuba intlama yesilivere ye-aluminium ingena ngengozi emehlweni, nceda uhlambe ngamanzi ubuncinane imizuzu eyi-15 kwaye ufune iingcebiso zonyango.
