Mvura Yakavakirwa Aluminium Paste | Aluminium Pigment
Tsanangudzo:
Aluminium Paste, chinhu chakakosha chesimbi pigment. Zvikamu zvaro zvikuru ichando chealuminium particles uye petroleum solvents muchimiro chenamira. Iri mushure mehunyanzvi hwekugadziridza tekinoroji uye kurapwa kwepamusoro, ichiita iyo aluminium flake pamusoro yakatsetseka uye yakatsetseka mupendero yakashambidzika, yakajairwa chimiro, particle size yekugovera kusungirirwa, uye yakanakisa inoenderana neiyo coating system. Aluminium Paste inogona kukamurwa kuita mapoka maviri: Leafing type uye non-leafing type. Munguva yekukuya, imwe mafuta asidhi inotsiviwa neimwe, izvo zvinoita kuti Aluminium Paste ive nehunhu hwakasiyana uye chitarisiko, uye maumbirwo ealuminium flakes ichando chechando, chiyero chehove uye dhora resirivha. Inonyanya kushandiswa mumagetsi emotokari, mapurasitiki asina simba, masimbi ekugadzirwa kwesimbi, marine coatings, kupisa-kupisa, kuvhara kwedenga uye zvichingodaro. Inoshandiswawo mupende yepurasitiki, hardware uye pendi yemidziyo yemumba, pendi yemudhudhudhu, pendi yebhasikoro zvichingodaro.
Hunhu:
Mvura Yakavakirwa Aluminium Pigment, inozivikanwawo seaqueous aluminium paste, yakagadziridzwa nekuvandudzwa kweaqueous coatings. Aluminium chinhu chine hupenyu amphoteric simbi uye chiri nyore kuita nemvura, asidhi uye alkali. Inofanirwa kutora yakakosha kurapwa kwepamusoro kana ichiwedzera mune aqueous resin system. Pakati pemusika nzira dzeaqueous aluminium paste dzinogona kukamurwa kuita 4 zvikamu:
1 Wedzera corrosion inhibitor; 2 Chromic acid kana chromate passivation; 3 Sirika yekupfekedza nzira; 4 Inorganic uye organic yakapetwa kaviri-yakavharwa kana interpenetrating network nzira (IPN). Nzira idzi dzine zvakanakira nekuipira zvakasiyana. Pamwe chete nezvinodiwa zvepamusoro zvekuchengetedzwa kwezvakatipoteredza, nzira mbiri dzekupedzisira dzichashandiswa zvakanyanya uye zvakanyanya.
Application:
Iyo aqueous aluminium paste inoshandiswa zvakanyanya muaqueous mota machira, fenicha uye imwe yekushongedza pendi, zvizorwa, kurongedza chikafu, matehwe nemachira, matoyi evana, nezvimwe.

Application Guide:
1.Foam slurry yakawanda,inures gare gare, ichikurudzira zvishoma nezvishoma uye kuwedzera aqueous coatings emulsion, inogona kuwedzera imwe dispersant zvakakodzera kudzivirira cluster uye particle precipitation.
2.Usaikuchidzira mukukurumidza, kana simba guru rekuveura richiparadza kupfekedza kwealuminium pigment; kumhanya kunotenderera kunofanirwa kudzora mu300-800rpm.
3.Kune mhedzisiro yakakwana, iwe unofanirwa kusefa zviri nani iyo aqueous coating.
4.Mukuchengetwa kwenguva refu, aluminium paste inogona kuburitsa zvidimbu. Unogona kuinyudza nemvura yakachena kana glycol ether maminetsi akati wandei, kurunga zvishoma uye wozobuda kunze.
5.Kuchengetedza: Dzivisa zuva rakananga; mushure mekushandisa aluminium paste, sunga madhiramu anovhara nekukurumidza.
Notes:
1. Ndapota iva nechokwadi chekusimbisa sampuli isati yashandiswa imwe neimwe yealuminium sirivheri paste.
2. Paunenge uchiparadzira aluminium-silver paste, shandisa pre-dispersing method: sarudza mushonga wakakodzera kutanga, wedzera mushonga mualuminium-silver paste ine reshiyo yealuminium-silver paste kune solvent se1: 1-2, kurunga. zvishoma nezvishoma uye zvakaenzana, uye wozoidururira muzvinyorwa zvakagadzirirwa.
3. Dzivisa kushandisa michina yekuparadzira yakakurumidza kwenguva yakareba panguva yekusanganiswa.
Mirayiridzo yekuchengetedza:
1. Sirivha yealuminium paste inofanira kuchengeta mudziyo wakavharwa uye tembiricha yekuchengetera inofanira kuchengetwa pa15℃~35℃.
2. Dzivisa kutarisana nechiedza chezuva chakananga, mvura uye tembiricha yakanyanyisa.
3. Mushure mekusunungura, kana paine yasara sirivheri aruminiyamu paste inofanira kuiswa chisimbiso pakarepo kudzivirira solvent evaporation uye oxidation kukundikana.
4. Kuchengetedzwa kwenguva refu kwealuminium sirivheri paste inogona kunge yakanyungudutsa kusagadzikana kana kumwe kusvibiswa, ndapota edza zvakare usati washandisa kuti urege kurasikirwa.
Matanho ekukurumidzira:
1. Kana moto, ndapota shandisa kemikari yehupfu kana jecha rinokosha rakaoma kuti udzime moto, usashandise mvura kudzima moto.
2. Kana aruminiyamu sirivheri paste inopinda netsaona mumaziso, ndapota geza nemvura kwemaminetsi gumi nemashanu uye tsvaga zano rekurapa.
