Adalemba pa 2018-09-17Njira yokutira ya Dacromet: zopangirazo zimapangidwira kuti zisungunuke m'madzi, kenako zimakutidwa pamwamba pa chogwirira ntchito chomwe chimakonzedweratu, chophikidwa kale ndikuwotchedwa kuti chipanga filimu yosasinthika.Njira yofunika kwambiri ndi iyi: kupukuta kwa workpiece → kuchotsa (kuphulika) → kuviika ❖ kuyanika (kapena kupopera) → kuyanika → kuphika kale → sintering → kuzizira → kuyang'ana → kuyika.
1. Kuwotcha: Kuchotsa mafuta osungunulira organic kapena alkaline solution.Kuchokera pamalingaliro achitetezo cha chilengedwe, degreasing ya alkaline iyenera kugwiritsidwa ntchito.Pambuyo pa degreased workpiece, pamwamba amafunika kuthiridwa ndi madzi.
The workpiece imayikidwa mu chidebe chotsekedwa, ndipo chotsukiracho chimayambitsidwa ndi kuthamanga kwakukulu ndikupopera kuti ayeretsedwe.Popeza pamwamba pa workpiece ndi mchere odana ndi dzimbiri mafuta, pawiri surfactant ndi emulsified kubalalitsidwa ndi wabwino Kutha mphamvu amasankhidwa.
2. Kuphulika kwa mfuti: Pofuna kupewa kuwonongeka kwa haidrojeni komanso kuipitsa chilengedwe, dzimbiri sigwiritsidwa ntchito potola, koma kuphulika kumagwiritsidwa ntchito.Makina owombera zitsulo omwe amagwiritsidwa ntchito pamakina owombera ali ndi mainchesi kuyambira 0.1 mpaka 0.6 mm, ndipo amapukutidwa ndi mpweya woponderezedwa.Fumbi lochotsedwa limasonkhanitsidwa ndi wosonkhanitsa fumbi lapadera ndikukhazikika.Kutsitsa ndi kutsika kuyenera kukhala kokwanira, apo ayi kukana kumamatira ndi kutukuta kwa zokutira kudzachepetsedwa.
3. Dip ❖ kuyanika: Chogwiritsira ntchito chogwiritsidwa ntchito chimamizidwa mu yankho lokonzekera la Dacromet.Chogwirira ntchitocho chimakhala choviikidwa kwa mphindi 2 mpaka 3 ndikugwedezeka pang'ono kenako ndikuwumitsa.Ngati workpiece ndi yayikulu, ipopeni.Pambuyo kuviika ❖ kuyanika kapena kupopera mbewu mankhwalawa, ngati pali kusagwirizana kapena kutayikira ❖ kuyanika pambuyo kuyendera, angagwiritsidwe ntchito ndi ❖ kuyanika burashi.
4. Kuphika kale, kuchiritsa: Chovala chophimbidwa chimayikidwa pa lamba wazitsulo zosapanga dzimbiri, ndipo zogwirira ntchito siziloledwa kumamatira wina ndi mzake, lowetsani ng'anjo ya sintering kwa mphindi 10-30, ndikuchiza kwa mphindi 15 mpaka 30.Kuphika kusanachitike, kuchiritsa kutentha ndi nthawi kumatsimikiziridwa makamaka ndi makulidwe a zokutira ndi kukula kwa workpiece ndi madzi opaka osiyanasiyana.Liwiro lotumizira lamba lamba wachitsulo chosapanga dzimbiri limayendetsedwa.
5. Pambuyo pa chithandizo: Ngati pamwamba pa chomangira ndi chovuta pambuyo pochiritsa, pamwamba pa chomangiracho chikhoza kutsukidwa ndi burashi yolimba.
