Kubwezeretsa kwa Solder Dross

Makina opangira ma tin slag ndi kuchepetsaamagwiritsa ntchito njira zakuthupi kuti achepetse malata opangidwa ndi oxidized mu ng'anjo ya malata apamwamba kukhala malata omalizidwa popanda kuwonjezera zopangira mankhwala kuti zitsimikizire mtundu wa malonda ndipo zitha kugwiritsidwa ntchito mwachindunji popanga, kupulumutsa ndalama zopitilira 50% ndikuwongolera bwino zachuma;

Kampani iliyonse yomwe imagwiritsa ntchito makina opangira mafunde / osankha ili nayo, koma ndi chiyani ndipo mungachepetse bwanji kapena kutaya?
Dross ndi 85-90% solder kotero ndi yofunika kwa kampani.Pamene mafunde akuwotchera mumlengalenga, ma oxides amapanga pamwamba pa solder yosungunuka.Iwo amasamutsidwa pamwamba pa mafunde ndi matabwa akukonzedwa kukakamiza solder ndi oxides kusakaniza pa bafa pamwamba ndi pansi pa pamwamba pa static mphika.Mlingo wa kutulutsa zinyalala umadalira kutentha kwa solder, chipwirikiti, mtundu wa aloyi / kuyera ndi zina zowononga / zowonjezera.Zambiri zomwe zimawoneka ngati zinyalala, kwenikweni, ndi tinthu tating'ono ta solder tokhala ndi filimu yopyapyala ya oxide.Pokhala chipwirikiti pamwamba pa solder, m'pamenenso nyenyeswa zimachuluka.Kutengera ndi kutulutsa komwe kumagwiritsidwa ntchito popanga zinyalala zimatha kukhala ngati matope kapena zambiri ngati ufa.Kuwunika kwa zinyalala zikasiyanitsidwa ndi solder kumawonetsa zotsalira kukhala ma oxide a malata ndi lead.

Pamene kusonkhana kumadutsa pa solder, zitsulo zosiyanasiyana pa bolodi zidzasungunuka kukhala malata osungunuka.Kuchuluka kwenikweni kwazitsulo zomwe zikukhudzidwa ndizochepa kwambiri, koma kuipitsidwa kwazitsulo kakang'ono kamene kangathe kusokoneza machitidwe a solder wave, ndipo kungasonyezedwe mu maonekedwe a solder.Nthawi zambiri, monga mkuwa ndi chitsulo chodziwika bwino chomwe chimagulitsidwa chidzakhala choyipa chodziwika bwino mu solder.The solder kwenikweni mu dothi komabe adzakhala ndi aloyi wokhutira chimodzimodzi ndi milingo ya kuipitsidwa monga mu solder mphika kotero ali ndi mtengo ndipo akhoza kugulitsidwa kwa katundu.Kuchuluka kwa solder mu dothi kumakhudza mtengo wobwezeredwa pazakale komanso mtengo wachitsulo panthawiyo.

Dothi lomwe lili pamwamba pa bafa losasunthika limateteza kumakutidwe ndi okosijeni kwina.Choncho, siziyenera kuchotsedwa kawirikawiri kuposa momwe ziyenera kukhalira.Pokhapokha ngati zisokoneza machitidwe a mafunde, zimalepheretsa kulamulira kwa mlingo wa solder kapena zikhoza kuyambitsa kusefukira kwa madzi pamene mafunde akutsegulidwa.Kamodzi patsiku nthawi zambiri zokhutiritsa anapereka mlingo olondola wa solder mu mphika akhoza kuyang'aniridwa ndi saloledwa kusiya.Ngati solder mlingo akutsikira izo zimakhudza solder yoweyula kutalika mwachindunji.Pa de-drossing kuchuluka kwa solder mu phala akhoza kulamulidwa ndi woyendetsa njira kuchotsa.Chisamaliro chingachepetse kwambiri kuchuluka kwa aloyi yabwino yochotsedwa posamba.Komabe ogwira ntchito nthawi zambiri sapatsidwa nthawi yochotsa madzi osamba m'njira yochepetsera zinyalala.

Kumbukirani kuti chigoba chimayenera kugwiritsidwa ntchito nthawi zonse pochotsa zinyalala pamafunde, ndikuyika m'chidebe chotsekedwa chomwe nthawi zambiri chimaperekedwa kwaulere kwa ogulitsa.Izi zimapewa kuthekera kwa tinthu ting'onoting'ono ta fumbi lolowa mumlengalenga.Ganizirani za kugwiritsa ntchito surfactant kuti mutulutse solder muzitsulo.Dola akhoza kugulitsidwa kwa wogulitsa malonda kuti ayeretsedwe ndikugwiritsanso ntchito pazinthu zina.

Ndi solder wopanda lead milingo ya zinyalala imatha kukhala yapamwamba koma imatha kusungidwa pamilingo yovomerezeka ndi kusankha koyenera kwa aloyi yoyambirira.Pamwamba pa solder ndi zizindikiro zidzakhala zosiyana ndi solder wopanda kutsogolera, chitsanzo chimodzi cha izi ndi mkuwa.Mu bafa yopanda kutsogolera milingo yamkuwa ikhoza kukhala pakati pa 0.5-0.8% poyambira ndikuwonjezeka panthawi yopanga.Mu bafa ya malata/lead izi zitha kuganiziridwa kuti ndizapamwamba kwambiri kuposa kuipitsidwa.
