Pankhani otentha choviikidwa kanasonkhezereka zitsulo chitoliro, ndondomeko yotentha-kuviika galvanizing zotsatira mu metallurgical chomangira pakati nthaka ndi zitsulo ndi mndandanda wa aloyi osiyana chitsulo-zinki. Mzere wothirira wothira moto umagwira ntchito motere:
◆Chitsulo chimatsukidwa pogwiritsa ntchito njira ya caustic. Izi zimachotsa mafuta / mafuta, dothi, ndi utoto.
◆ The caustic cleaning solution ndi kuchapidwa.
◆Chitsulocho amazifutsa mu acidic njira kuchotsa mphero sikelo.
◆Nkhani ya pickling imachapidwa.
◆A flux, nthawi zambiri zinc ammonium chloride amagwiritsidwa ntchito pazitsulo kuti aletse makutidwe ndi okosijeni pamalo oyeretsedwa akakhala pamlengalenga. The flux amaloledwa kuti ziume pa zitsulo ndi zothandizira mu ndondomeko ya madzi zinki wetting ndi kutsatira zitsulo.
◆Chitsulocho amaviika mu bafa yosungunuka ya zinki ndi kusungidwa mmenemo mpaka kutentha kwa chitsulocho kukhale kofanana ndi kwa bafa.
Mwaukadaulo, malata ndi njira yokutira chitsulo ndi chitsulo chosanjikiza cha zinki pomiza chitsulo mu bafa la zinki wosungunuka pa kutentha kozungulira 840 °F (449 °C). Zinc (Zn) ikakhala mumlengalenga, zinc (Zn) yoyera imakumana ndi okosijeni (O2) kupanga zinc oxide (ZnO), yomwe imakhudzidwanso ndi mpweya woipa (CO2) kupanga zinc carbonate (ZnCO3), imvi nthawi zambiri, yamphamvu kwambiri. zinthu zomwe zimateteza zitsulo pansi kuti zisawonongeke nthawi zambiri. Nthawi zambiri, chitoliro choviikidwa chamalata chimakhala ndi mtengo wapamwamba wachitsulo kuposa mitundu ina ya chitoliro chomwe chikugwiritsidwa ntchito chifukwa cha kukwera mtengo kwake pamsika.
Pazogwiritsa ntchito, monga njira zina zodzitetezera ku dzimbiri, malata amateteza kwambiri zinthu zachitsulo pochita ngati chotchinga pakati pa chitsulo ndi mlengalenga. Komabe, zinki ndi chitsulo chochuluka cha electronegative poyerekeza ndi chitsulo. Ichi ndi chikhalidwe chapadera cha galvanizing. Makamaka, pamene zokutira zamalata zawonongeka ndipo chitsulo chachitsulo chikuwonekera mumlengalenga, zinki zimatha kupitiriza kuteteza chitsulo kupyolera mu galvanic corrosion. Kupatula apo, chifukwa cha kulimba kwake komanso zinthu zoletsa dzimbiri, mapaipi ambiri ozizira achitsulo amatha kubwezeretsedwanso ndikugwiritsidwanso ntchito, zomwe zimapulumutsa ndalama zambiri panthawi yokonza positi.
Ndi wosanjikiza wa chitetezo, mapaipi angagwiritsidwe ntchito m'madera akunja, ndipo akhoza kupirira kuvulazidwa ndi zina mwa zotsatira zachilengedwe. Mayesero ndi kafukufuku wasonyeza kuti moyo wapakati wa zitsulo zogwiritsidwa ntchito ngati zomangira zimapitirira zaka 50 kumidzi ndi zaka 20-25 kapena kuposerapo m'matauni kapena m'mphepete mwa nyanja. Pachifukwa ichi, makontrakitala amatha kugwiritsa ntchito mankhwalawa molimba mtima pantchitoyo. Monga katswiri zitsulo chitoliro wopanga ku China, tadzipereka kupanga mitundu yosiyanasiyana ya chitoliro zitsulo ntchito zanu. Kuti mudziwe zambiri, mutha kulumikizana nafe nthawi iliyonse.
