Aluminium Gqiba: Technology kunye namacebiso

aluminiyamu Ukupeyinta kunye nezinye zesinyithi nonferrous lu dityanisiwe neengxaki ezithile ezinxulumene igcwala ngokukhawuleza. Phantsi yempembelelo ioksijini, i-bhanya oxide amiliswe kwi material enciphisa adhesion nawuphi na ukutyabeka, kuquka ipeyinti kunye kwenziwa. Ngenxa yale self-imibala rhoqo mifutshane, ayikhangeleki ngendlela engcono.

anodizing

Nangona uluhlu mihla ezaqanjwa primer, bona musa ukunika yifuna, kwaye ngepeyinti uxobule umaleko kwi nempembelelo encinane.

Ukuphucula adhesion lwepeyinti aluminium iindawo inokuba esebenzisa anodizing intsimbi. Le nkqubo iqulathe kwi unyango electrochemical okanye imichiza, ngenxa apho kwanciphisa igcwala ngamandla. Phantse zonke iimveliso zesinyithi non-ayoni, umbala kwiimeko mveliso, uwele anodizing kwizixhobo ezikhethekileyo.

Izinto kunye nezixhobo

Ekhaya, unako kwakhona ukwenza le nkqubo okanye usebenzise ezizodwa primer. Powder enamathela aluminium kunye steel nehlawulelweyo kuthatha ixesha kwaye kwandisa iindleko, kodwa umphumo kuyinto efanelekileyo. Pre-imfuneko ukulungiselela izixhobo kunye nezinto, ngaphandle apho akunakwenzeka kukuzuza finishes ezingoomahambehlala ezikumgangatho ophezulu:

• amanzi, irola okanye ibrashi;
• lokukhuhla nge ubukhulu okuziinkozo entle (efunekayo xa aluminium ngesicamba ngaphezulu);
• izikhongozeli kukubekwa iinxalenye ukuphathwa;
• iviniga ukuxuba nokwakheka ipeyinti;
• aniline;
• kuthetha ukuba bamafutha;
• izithako electrolytic ukwakheka (amanzi, ityuwa, soda).

inkqubela yomsebenzi

izithako aluminium Paint luqala ezimbaxa ukubunjwa electrolytic kunye nolungiselelo isicombululo. Amaxabiso yamanzi kufuneka kwanele ukuba ngokuntywiliselwa ngokupheleleyo aluminium element. Ulwelo engumphumela agalelwa kwizikhongozeli ezibini twatse. Omnye wabo lizele soda kwi om-1 ukuya (soda namanzi, ngokulandelelana) 5, omnye ityuwa zafakwa kwi-mali efanayo. Emva koko ulwelo kwakudalwa de ukupheliswa ngokupheleleyo kudla. Inyathelo olandelayo ngococo ubume kunye ambaxa iimpahla ezimbini. Isisombululo kufuneka ime ngeli xesha kunokwenzeka ukuba khazimlisani umphezulu metal. Igrisi kunye nokungcola iyasuswa ngelaphu zifakwe acetone.

Ngaphezu koko, izinto eziliqela yoxukuxwa phantsi kwamanzi aphilileyo zifakwe kwisingxobo kunye nesisombululo. Kufuneka kuqala banxibe iiglavu zerabha yokhuseleko.

I-terminal ezigxekayo oludityaniswe emanzini amalungu umthamo, eyakhayo - ngqo izinto ngokwabo. Anodizing uqhubeka iiyure 2-3 de Tint bamantshontsho hina.

Ngapha koko, oku kungenziwa lealuminium yokudaya ekhaya. Ukwakheka Umbala ibandakanya ukusuka ilitha 1 ulwelo, 20 grams idayi aniline 2 ml iviniga. Isisombululo kufuneka lashushu degrees 80 kunye sibanga oluqhubekayo. Iimveliso bayagqobhoza, bayangena inkqubo anodizing zibekwe kwisingxobo kunye sisincoko Umbala ukuba imizuzu eli-15-20.

Aluminium Paint: Technology

Anodizing asiyo kufuneka-bona khona. Ukuba kuyimfuneko, ungenza ngaphandle kwale nkqubo, esebenzisa primer, nto leyo evumela ukunyusa umgangatho adhesion ipeyinti nentsimbi. aluminiyamu ayiqabe primer lwenziwa ngokusebenzisa ezi zibonelelo zilandelayo nezixhobo:

• separafini, acetone, kunye nayiphi na enye indlela bamafutha;
• paint olulodwa metal;
• primer on alkyd;
• lokukhuhla;
• irola okanye elibhulu.

Aluminium Paint ekhaya luqala ukuphatha phezu kunye sandpaper ukunyusa primer adhesion. Eyona ndlela ilungileyo ibiya kuba esirhabaxa ezinomyinge ngeso lenyama. Ngemva kokuba imveliso besila iphathwa nge acetone ngelaphu, ilaphu iintshengece-free. Ukukhusela ulusu kwezandla kuyimfuneko ukusebenzisa iiglavu zerabha.

Okulandelayo, phezu lulungele. Kulo mzekelo, kufuneka ayisasaze ngokukhawuleza kwangoko emva kokuba unyango, kuba ichaphazela iyahlala nokuthembeka ukutyabeka. Kucetyiswa ukuba kulungiselelwe primer phambi kokuba uqale sanding komhlaba. Wachuba iindawo kunye izitenxo eziye kwaphakama, emva kokufaka primer, asuswe ngokusebenzisa sanding iphepha.

Aluminium Paint senziwe maleko ubuncinane ezimbini, apho phambi kokuba isicelo maleko ngasinye ongaphambili kufuneka womile.

Ipeyinti powder

Kuba imibala aluminium umgubo yokuqamba nayo kusetyenziswa. Inika ukutyabeka eyomeleleyo ethembekileyo ngohlobo umaleko monolithic, Uyabahombisa umbandela nje kuphela, kodwa kunciphisa amathuba okuba nokumelana.

Inyathelo lokuqala ukulungiselela kumphezulu. Xa iimeko zoshishino kunye iindawo isuswe neetyuwa kunye ukungcola, uze yoxukuxwa ngamanzi. Ngaphandle bamafutha aluminiyam umgubo ipeyinti ukutyabeka eqhelekileyo iquka phosphate, nto leyo eyandisa umgangatho intsimbi kunye nepeyinti adhesion.

Ke izinto phantsi yaphuse phantsi kwempembelelo amaqondo obushushu aphezulu kunye nokupholisa. Okubaluleke kakhulu yinkqubo polymerization, nezibabandakanya ekusebenziseni i nentlaka umaleko ekhethekileyo phantsi koxinzelelo lomoya. Lo msebenzi wenziwe ngoncedo le atomizer electrostatic uyila umaleko obhityileyo phezu komhlaba.

Emva yokuphawulwa ngeinki iimveliso aluminiyam zibekwe eziko ekhethekileyo yaye lashushu degrees 200 imizuzu 10-15. Ayengawokuphilisa umaleko kwenzeka ebudeni Ukupholisa intsimbi.

Ukusetyenziswa izixhobo ezikhethekileyo kunye yamaziko nzima inkqubo ukupeyinta imixube powder kwelo khaya, yiyo ke le nto idla indawo anodizing.

Powder enamathela kunokwenzeka naluphi na amacandelo aluminium. Eyona ngokubanzi fumene ubuchule iinxalenye daka ezo zenzelwe ukusetyenziswa kwiqondo lobushushu ukuya degrees 220.

Umbala spray

Phambi isicelo obu bugcisa isebenzisa ukulungiselela impahla eqhelekileyo, umzekelo hilaha ku anodizing. iimpawu ezongezelelweyo nokuphawula imfuneko yokugcina umgama olwaneleyo phakathi komhlaba kunye ibhaluni, nokusebenzisa ezininzi kuThixo lamanqanaba. Ekubeni umaleko nokufumba yangaphambili kufuneka imizuzu engama-20 ubuncinane, kodwa emva koko ukuze isale umaleko ngepeyinti elandelayo. Inani lamanqanaba aguquguquka ukusuka iinkcukacha umgangatho izinto ukupeyinta, kunye nokusebenza. Kwi-avareji, oko ziyahluka kuluhlu 3-15 depositions.

iimpawu

Kubalulekile ukuba ukulibala malunga athile ishukumisa lombhobho, oko kuya kukunceda ukuba uphephe drip kunye amabala. Kwezinye iimeko kusenokubakho ukuvaleka umlomo. Kuba zokucoca kuyimfuneko ukujika ibhotile leyo ze sokutshiza nokwakheka ukuya kwindawo, de kuya kuvela sisincoko ngaphaya.

Emva kokugqitywa umbala phambi iintsalela kufuneka zisuswe kwindawo ekhuselweyo elangeni. Izixhobo ezisetyenziswa zicocwa kunye kuphela. Painting lealuminium eveliswa ngendlela efanayo, kungakhathaliseki ukuba izinto ezisetyenziselwa umsebenzi.

iintlobo yepeyinti

Isiphumo sokugqibela iphenjelelwa aliwenzi kuphela bonke ubuqili umsebenzi, kodwa umgangatho kunye iimpawu imibala ekhethiweyo. Ithi kunayo yonke ineenketho ezininzi:

• An kuqamba acrylic kwahlukile ukumelana umonakalo evela ukufuma kunye namaqondo kakhulu. Ipeyinti sifakwa phezu umaleko primer.
• Epoxy eyenziweyo ukusebenzisa nentlaka ezizodwa, ngenxa apho uneempawu ezifana iyahlala namandla.
• Aniline wayeyalelwe wadalwa ukuze noshishino lwempahla eyolukiweyo le. Le ayinikezi ezilungele iimveliso aluminium zigqithile inkqubo anodization. Kodwa ayikho ngaphandle ethile, ingakumbi, ukwakhiwa enokumelana ephantsi ukufuma kunye nokukhanya kwelanga.
