Malangizo apakati: Zinc alloys amagwiritsidwa ntchito kwambiri mu bafa, matumba, nsapato ndi zowonjezera, chifukwa cha zosavuta zake, pulasitiki, zotsika mtengo komanso zogwira mtima kwambiri.

Zinc alloy imagwiritsidwa ntchito kwambiri pazinthu zaukhondo, zikwama, nsapato ndi zovala zowonjezera chifukwa cha mawonekedwe ake osavuta, mapulasitiki olimba, otsika mtengo komanso okwera kwambiri.Komabe, vuto la matuza a aloyi a zinc (electroplating; kupopera) lakhala likuvutitsa abwenzi a mafakitale a hardware ndi mafakitale opanga magetsi.

Zomwe zidachitika pakupanga thovu la zinki m'mafakitole opanga ma electroplating m'mafakitale angapo a hardware ndi mwachidule motere:

1. Kumayambiriro kwa mapangidwe a zinc alloy products, tiyenera kuganizira za kukhazikitsidwa kwa doko lodyera, doko lotulutsa slag ndi doko lotulutsa nkhungu.Chifukwa otaya njira workpiece ndi kudyetsa ndi kutulutsa slag ndi yosalala, palibe mpweya entrapment, palibe madontho madzi, palibe thovu mdima, amene mwachindunji zimakhudza ngati wotsatira electroplating ndi kuwira.Chogwirira ntchito chokhala ndi chakudya chokwanira komanso chotulutsa slag chili ndi malo osalala, kuwala koyera, ndipo palibe madontho amadzi.

2. Pakukula kwa nkhungu, tiyeneranso kuganizira za tonnage ndi kupanikizika kwa makina opangira nkhungu.Tidakumana ndi 20-30% matuza pambuyo pa electroplating ya zinc alloy.A hardware fakitale Bwenzi loyamba monyoza mayeso, ndi 8 zidutswa nkhungu, ndi mmene kuthetsa vuto la 20-30% pamaso thovu, ndipo potsiriza kuletsa nkhungu 4 zidutswa, ndi kusintha 4 zidutswa nkhungu.

3. Njira yothetsera calendering, phala lopukuta ndi oxide wosanjikiza pamwamba pa pretreatment silimatsukidwa, ndipo pamwamba pa workpiece pambuyo pa calendering ndi kupukuta ndi kowala.Ogwira ntchito ambiri mu pickling ndondomeko ya electroplating chomera pickling wamba, chifukwa pamwamba Ufumuyo calendering wothandizira si kutsukidwa, ndi thovu yaitali kuonekera.Kuonjezera apo, pali mgwirizano waukulu pakati pa ma calendering agents omwe amasankhidwa ndi chomera cha calendering ndi kupukuta, ndipo opangira ma surfactants mu ma calendering agents ndi ovuta kwambiri kutsuka.

4. Mankhwalawa asanalowe mumadzi osambira amkuwa amkuwa, pamakhala filimu ya oxide (pickling filimu) pamwamba pa workpiece.Mafilimu ochotsa sera ndi mafuta samachiritsidwa kwathunthu.Choncho, ndikofunika kwambiri kuchotsa filimuyo.M'zaka zoyambirira, imatha kuchotsedwanso ndi anti staining salt.Tsopano, sikuloledwa kutaya madzi otayidwa okhala ndi anti staining salt.Ndibwino kugwiritsa ntchito ufa wochotsa filimu wa lj-d009, womwe uli ndi mphamvu yabwino kuposa mchere wothimbirira, umathanso kuchotsa nickel wosanjikiza, ndipo kutulutsa kwa COD kumakwaniritsa miyezo yapadziko lonse lapansi.

5. Pali zinthu zambiri za organic ndi zonyansa mumadzi osambira amkuwa amkuwa, ndipo cyanide yaulere sapezeka.Yesani kapangidwe ka thanki yamkuwa yamchere kuti muwone ngati sodium cyanide ndiyotsika kapena sodium hydroxide ndiyokwera!Ngati muwonjezera chowunikira mosamala, chowunikira chimakhala chapamwamba, ndipo kuyeretsa kwa thanki yamkuwa yamchere ndikofunikira kwambiri.Akuti mankhwala a carbon ayenera kuchitidwa kamodzi pa masiku 3-5

6. Mayendedwe a silinda yamkuwa ya alkali ndiyofunikanso kwambiri.Kaya anode amasungunuka bwino komanso ngati mbale yamkuwa ya anode ndiyokwanira kumayambitsa matuza.

7. Zinc aloyi mankhwala chithuza akatuluka mu uvuni;zikhoza kukhala chifukwa cha kutentha kwa uvuni kosafanana, ndiko kuti, kutentha kwambiri.Chifukwa kuponyera kufa sikolimba, ndikosavuta kuyika asidi m'madontho amadzi ndi ma trachomas a aloyi ya zinki.Ngakhale pali zokutira pamwamba, asidi ndi nthaka adzakhalabe ndi mankhwala, kupanga kuchuluka kwa haidrojeni H.Pamene kuthamanga kwa mpweya mkati ndipamwamba kuposa kuthamanga kwa mumlengalenga kumlingo wina, ndipo kutentha kwakukulu kudzatulutsa thovu
