Kodi Mukudziwa Makhalidwe a Mapaipi Opangidwa ndi Galvanized?

(1) Kupanga koyera kwapadera
Chitoliro chopangidwa ndi galvanized chimagwiritsa ntchito njira yopangira ma electroplating ya sulfate ya zinc-iron alloy, zomwe zikutanthauza kuti pali mabowo olunjika pakati pa migolo yopangira ndi migolo popanda kunyamula kapena kudzaza yankho. Njira iliyonse yopangira imakhala ndi njira yoyendetsera madzi. Mayankho omwe ali mu thanki iliyonse, monga yankho la asidi ndi alkali, yankho la electroplating, yankho lotulutsa kuwala ndi yankho la passivation, ndi zina zotero, amangobwezeretsedwanso ndipo satuluka kapena kutulutsidwa kunja kwa dongosolo. Mzere wopangira uli ndi matanki 5 okha oyeretsera, omwe amagwiritsa ntchito kayendedwe ka madzi. Gwiritsaninso ntchito ndikutulutsa madzi nthawi zonse, makamaka munjira zopangira zomwe sizipanga madzi otayika popanda kuyeretsa pambuyo pa passivation.
(2) Kufunika kwa zida zamagetsi
Kuyika ma electroplating a mapaipi opangidwa ndi magetsi ndi ma waya amkuwa ndi chimodzimodzi ndi kuyika ma electroplating mosalekeza, koma zida zoyika ndi zosiyana. Thanki yoyikamo yapangidwa ndi mawonekedwe owonda a waya wachitsulo. Thupi la thanki ndi lalitali, lalikulu koma losaya. Pakuyikamo ma electroplating, mawaya achitsulo amadutsa m'mabowo ndikufalikira pamwamba pamadzi molunjika, kusunga mtunda pakati pawo. Komabe, chitoliro chopangidwa ndi magetsi ndi chosiyana ndi waya wachitsulo chifukwa chili ndi mawonekedwe ake apadera ndipo zida za thanki ndi zovuta kwambiri. Thupi la thanki limapangidwa ndi zigawo zapamwamba ndi zapansi. Gawo lapamwamba ndi thanki yoyikamo ndipo gawo lapansi ndi thanki yosungiramo madzi yozungulira, ndikupanga thupi la thanki longa trapezoid lomwe ndi lopapatiza pamwamba ndi lalikulu pansi. Pali njira yogwirira ntchito ya electroplating ya mapaipi oyikamo magetsi mu thanki yoyikamo magetsi. Pali mabowo awiri pansi pa thanki omwe amalumikizana ndi thanki yosungiramo madzi yotsika, ndikupanga njira yobwezeretsanso yankho loyikamo madzi ndi pampu yonyowa. Chifukwa chake, mapaipi oyikamo magetsi ndi ofanana ndi kuyikamo magetsi kwa waya wachitsulo, ndipo magawo oyikamo ndi osinthika. Komabe, mosiyana ndi waya wophimba ndi chitsulo, njira yophimba mapaipi opangidwa ndi galvanized nayonso ndi yosinthasintha.
(3) Kukonza bwino kwa sulfate galvanizing
Ubwino wa sulfate galvanizing ndi wakuti mphamvu yamagetsi ndi yokwera kufika pa 100% ndipo kuchuluka kwa chitsulo choyikidwamo ndi kofulumira, komwe sikungafanane ndi njira zina zoyikamo chitsulo. Chifukwa chakuti crystallization ya chitsulo choikidwamo sikokwanira, mphamvu ya kufalikira ndi mphamvu yakuya yoyikamo chitsulo ndi yofooka, kotero ndi yoyenera kokha mapaipi oyikamo chitsulo ndi mawaya okhala ndi mawonekedwe osavuta a geometric. Njira ya sulfate electroplating zinc-iron alloy imakonza njira yachikhalidwe yoyikamo chitsulo choyikidwamo chitsulo. Zinc sulfate yaikulu yokha ndi yomwe imasungidwa, ndipo zigawo zotsalazo zimatayidwa. Mchere wokwanira wachitsulo umawonjezedwa ku njira yatsopano yoyikamo chitsulo choyikidwa ... Machitidwe opanga zinthu atsimikizira kuti akagwiritsidwa ntchito popangira mawaya ndi mapaipi mosalekeza, tinthu ta utoto timakhala tating'ono komanso towala kuposa tomwe tinali toyambirira, ndipo kuchuluka kwa utoto kumakhala kofulumira. Kukhuthala kwa utoto kumafika pakufunika mkati mwa mphindi ziwiri kapena zitatu.
(4) Kutembenuka kwa sulfate zinc plating
Kupaka sulfate ya sulfate ya zinc-iron alloy kumasunga zinc sulfate, mchere waukulu wa sulfate zinc plating. Zinthu zina monga aluminium sulfate, alum (potassium aluminium sulfate), ndi zina zotero zitha kuwonjezeredwa ku bafa lopaka pulasitiki panthawi ya chithandizo kuti pakhale mpweya wosasungunuka wa hydroxide. Chotsani; pa zowonjezera zachilengedwe, onjezerani ufa woyambitsa kaboni kuti muchotse mwa kusakaniza.
Mayeso a opanga mapaipi opangidwa ndi galvanized awonetsa kuti aluminium sulfate ndi potassium aluminium sulfate ndizovuta kuchotsa kwathunthu nthawi imodzi ndipo zimakhudza kuwala kwa chophimbacho, koma sichowopsa ndipo chitha kuchotsedwa kuti chigwiritsidwe ntchito. Pakadali pano, kuwala kwa chophimbacho kumatha kubwezeretsedwanso kudzera mu mankhwala ndi yankho. Onjezani zosakaniza zomwe zikufunika malinga ndi njira yatsopano kuti mumalize kusinthaku.
