Aluminiyamu kufa kuponyera mankhwala pamwamba mankhwala

Aluminiyamu kufa kuponyera mankhwalamankhwala pamwamba

Aluminium alloy die casting products, mankhwala pamwamba zambiri: kupopera ufa (ufa kupopera mbewu mankhwalawa), utoto, kupopera mafuta, makutidwe ndi okosijeni, sandblasting, electroplating ndi zina zotero. Malinga makulidwe ndi mapeto a padziko mankhwala azitsulo zotayidwa za aluminiyamumankhwala.

1, kupopera mbewu mankhwalawa ndi kupopera mbewu mankhwalawa pamwamba pa workpiece ndi zida zokuzira ufa. Pansi pa zochita za electrostatic, ufa adzakhala wogawana adsorbed pamwamba pa workpiece kupanga ❖ kuyanika powdery. Kupaka ufa pambuyo pophika kutentha kwakukulu, kusanja ndi kuchiritsa, kukhala ndi zotsatira zosiyana (mitundu yosiyanasiyana ya zotsatira zopaka ufa) zomaliza; Kupopera ufa ndikwapamwamba kuposa kupopera utoto mu mphamvu zamakina, kumamatira, kukana dzimbiri, kukana kukalamba ndi zina, ndipo mtengo wake ndi wotsika kuposa wa utoto wopopera ndi zotsatira zomwezo.

Ufa kupopera mbewu mankhwalawa, kawirikawiri amagawidwa mu ufa panja ndi m'nyumba ufa. Zitsanzo zimatha kusinthidwa kuzinthu zosiyanasiyana, monga zosalala, mchenga, thovu, etc.

2, njira yeniyeni yophika utoto ndikugwiritsa ntchito aluminium alloy phosphating pambuyo kupopera mbewu mankhwalawa, kupopera mbewu mankhwalawa mukaphika, kupaka koteroko sikungoletsa kuwononga komanso kuvala kowala, kosavuta kugwa.

Aluminium die casting products Surface pretreatment

(1) 1 kuchotsa mafuta; 2 madzi; 3 kukhumudwa; 4 osambitsidwa; 5 ulonda; 6 otsuka; 7 phosphating; 8 osambitsidwa; 9 osambitsidwa; 10 kuyanika;

Katatu, kupopera mbewu mankhwalawa ndi dzina la pamwamba ❖ kuyanika processing wa mankhwala mafakitale, kupopera mafuta processing zambiri okhazikika mu pulasitiki kupopera mafuta, chophimba kusindikiza, PAD yosindikiza processing; EVA, mphira ndi mtundu wina wa nsapato, kusindikiza pazenera. Ndi mzere kupopera mbewu mankhwalawa, zenera kusindikiza mzere, pad makina osindikizira ndi zipangizo zina, ndipo malinga ndi zofuna za makasitomala, kupanga kukana kutentha, kukana kukangana, UV kukana, mowa kukana, kukana mafuta ndi zinthu zina. Kukonzekera: zinthu zamagetsi: utoto wamba wopopera, utoto wa PU, utoto wa mphira (mtundu wa utoto), (monga: disk U, MP3, kamera, zotumphukira zapaintaneti ndi zinthu zina zamagetsi. Atha kupopera mavuto omwe amakumana nawo pakuumba jekeseni, monga mizere ya gasi, zolumikizirana, ndi zina zambiri, amakhala ndi chidziwitso pakupopera utoto wa rabara (penti yamanja), kukhala ndi ukadaulo wokonzanso utoto.

4, okosijeniAluminiyamu aloyi pamwamba makutidwe ndi okosijeni, oyenera makutidwe ndi okosijeni conductive, aluminiyamu kapena mbiri zotayidwa, oyenera anodic makutidwe ndi okosijeni.

Mtundu wa Aluminium alloy oxidation nthawi zambiri umakhala wachilengedwe, wabuluu wakumwamba

1. Anodic makutidwe ndi okosijeni ikuchitika pansi pa chikhalidwe cha voteji mkulu, amene ndi electrochemical anachita ndondomeko; Conductive oxidation ndi njira yodziwikiratu yomwe imasowa magetsi koma kumizidwa mu njira yamadzimadzi. 2. Anodic oxidation imatenga nthawi yayitali, nthawi zambiri mphindi zingapo, pomwe conductive oxidation imangotenga masekondi angapo. 3. Kanema wa Anodic oxidation ali ndi ma microns angapo mpaka ma microns ambiri, komanso filimu yolimba komanso yosamva, komanso filimu yotulutsa makutidwe ndi okosijeni yopangidwa ndi ma microns 0.01-0.15 okha. Simavala bwino, koma imayendetsa magetsi ndikukana dzimbiri mumlengalenga, womwe ndi mwayi wake.

5, kuphulika kwa mchenga

Kupopera mbewu mankhwalawa wosanjikiza mchenga padzikozitsulo zotayidwa pzaluso zimatha kukulitsa kugundana kwa malo olumikizana ndikuwonjezera kudalirika kwa kulumikizana. Mchenga makulidwe, tirigu ndi osiyana kwambiri.

6, electroplating

Electroplating ndi njira yomwe zitsulo kapena aloyi zimayikidwa pamwamba pa workpiece ndi electrolysis kupanga yunifolomu, wandiweyani ndi cohesive zitsulo wosanjikiza, amene amatchedwa electroplating. Mwachidule, ndi kusintha kwa thupi ndi mankhwala kapena kuphatikiza. Kugwiritsa ntchito njira ya electroplating yomwe timagwiritsa ntchito nthawi zambiri pazifukwa izi: A. Anti-corrosion B. Kukongoletsa kodzitetezera C. Kupewa kung'ambika!
