Dheecaan Aluminium ah oo ku salaysan Biyo |Aluminium Pigment
Sharaxaad:
Aluminium Paste, waa midab bir ah oo lama huraan ah.Qaybaheeda ugu muhiimsan waa walxaha aluminium ee flake barafka iyo dareerayaasha batroolka ee qaabka koollada.Waa ka dib markii technology processing gaar ah iyo daaweynta dusha, samaynta aluminium flake dusha siman oo cidhif siman hagaagsan, qaabka caadiga ah, qaybinta size qaybinta fiirsashada, oo aad u fiican oo la mid ah nidaamka daahan.Xabagta aluminiumka waxaa loo qaybin karaa laba qaybood: nooca caleenta iyo nooca aan caleenta lahayn.Inta lagu jiro habka wax lagu shiidi karo, hal asiidh dufan ah ayaa lagu beddelayaa mid kale, taas oo ka dhigaysa Aluminium Paste sifooyin iyo muuqaal gebi ahaanba kala duwan, iyo qaababka jajabyada aluminiumku waa barafka, miisaanka kalluunka iyo dollarka qalinka ah.Inta badan loo isticmaalo dahaadhida baabuurta, dahaarka caagga daciifka ah, dahaarka warshadaha biraha, dahaarka badda, dahaarka kulaylka u adkaysta, dahaarka saqafka iyo wixii la mid ah.Waxa kale oo loo isticmaalaa rinjiga caagga ah, rinjiga qalabka iyo qalabka guriga, rinjiga mootooyinka, rinjiga baaskiilka iyo wixii la mid ah.
Astaamaha:
Biyaha ku salaysan Aluminium Pigment, oo sidoo kale loo yaqaan koollada aluminium aqueous, oo lagu sameeyay horumarinta dahaadhka aqueous.Aluminiumku waa curiye bir ah oo firfircoon oo amphoteric ah waana sahlan tahay in lagaga falceliyo biyo, aashito iyo alkali.Waa inay qaadato daawaynta dusha sare ee gaarka ah marka lagu daro nidaamka resin aqueous.Suuqa waxaa ka mid ah hababka koollada aluminium aqueous waxaa loo qaybin karaa 4 qaybood:
1 Ku dar dawooyinka daxalka;2 Chromic acid ama chromate passivation;3 Habka daahan silica;4 Habka shabakadaha isku-xidhka ah ee laba-dahaarka leh ama kuwa is-dhex-galka ah (IPN).Hababkani waxay leeyihiin faa'iidooyin iyo faa'iido darrooyin kala duwan.Iyadoo ay weheliso shuruudaha sare ee ilaalinta deegaanka, labada hab ee ugu dambeeya ayaa loo isticmaali doonaa in ka badan iyo in ka badan.
Codsiga:
Qurxinta aluminium aqueous waxaa si weyn loogu isticmaalaa daahan baabuurta aqueous, alaabta guriga iyo rinjiga kale ee qurxinta, waxyaalaha la isku qurxiyo, baakadaha cuntada, maqaarka iyo marada, alaabta carruurtu ku ciyaarto, iwm.

Hagaha Codsiga:
1.Foam slurry dhowr ,inres ka dib, si tartiib ah u walaaqaya oo ku dar emulsion daahan aqueous, ku dari kartaa qaar ka mid ah kala firdhiyey si habboon si looga fogaado cluster iyo roobab qayb.
2.Ha ku kicin xawaare sare, haddii ay dhacdo in xoogga sare ee dhogorta uu burburiyo daahan ee midabka aluminium;Xawaaraha wareeggu waa inuu xakameeyaa 300-800rpm.
3.Natiijooyinka ugu fiican, waa inaad si fiican u shaandhayso daahan aqueous.
4.In kaydinta muddada dheer, koollada aluminium ayaa laga yaabaa inay abuuraan qaybo.Waxaad ku qooyn kartaa biyo saafi ah ama glycol ether dhowr daqiiqo, walaaq wax yar ka dibna soo bixi doona.
5. Kaydinta: Ka fogow iftiinka qorraxda tooska ah;Ka dib markaad isticmaasho koollada aluminiumka, xidh daboolka durbaanka dhawaan.
Xusuusin:
1. Fadlan hubi inaad xaqiijiso muunada ka hor isticmaalka kasta ee koollada qalinka ah ee aluminium.
2. Markaad kala firdhiso koollada aluminium-silver, isticmaal habka hore-u-qaybinta: dooro dareeraha ku habboon marka hore, ku dar dareeraha ku dheji koollada aluminium-silver oo leh saamiga aluminium-silver ee dareeraha sida 1: 1-2, walaaq si tartiib ah oo siman, ka dibna ku shub walxaha aasaasiga ah ee diyaarsan.
3. Iska ilaali inaad isticmaasho qalabka kala firdhinta xawaaraha sare leh muddo dheer inta lagu jiro habka isku darka.
Tilmaamaha kaydinta:
1. Xadhkaha aluminiumka qalinka ah waa inuu ilaaliyaa weelka oo daboolan iyo heerkulka kaydinta waa in lagu hayaa 15 ℃ ~ 35 ℃.
2. Ka fogow soo-gaadhista tooska ah ee iftiinka qorraxda, roobka iyo heerkulka xad-dhaafka ah.
3. Furitaanka ka dib, haddii ay jiraan wax ka haray koollada aluminiumka qalinka ah waa in isla markiiba la xidhaa si looga fogaado uumiga dareeraha ah iyo fashilka oksaydhka.
4. Kaydinta muddada-dheer ee koollada qalinka ah ee aluminiumku waxay noqon kartaa isbedbeddelka dareeraha ama wasakh kale, fadlan dib u tijaabi ka hor intaanad isticmaalin si aad uga fogaato luminta.
Tallaabooyinka degdegga ah:
1. Haddii uu dab kaco, fadlan isticmaal budada kiimikaad ama ciid gaar ah oo qallalan si aad u damiso dabka, ha isticmaalin biyo si aad u damiso dabka.
2. Haddii koollada qalinka ah ee aluminiumku ay si lama filaan ah indhaha u gasho, fadlan biyo ku nadiifi ugu yaraan 15 daqiiqo oo raadso talo caafimaad.
