Chitsulo chachitsulo chagalasi

Pepala lopangidwa ndi galvanized ndi chitsulo chomwe pamwamba pake chimakutidwa ndi zinc.Galvanizing ndi njira yotsika mtengo komanso yothandiza yopewera dzimbiri yomwe imagwiritsidwa ntchito padziko lonse lapansi pafupifupi theka la zinki padziko lonse lapansi.
Ntchito:
Ngalava zitsulo mbale ndi kuteteza pamwamba pa mbale zitsulo ku dzimbiri kutalikitsa moyo utumiki wake, wokutidwa ndi wosanjikiza zitsulo nthaka pamwamba pa mbale zitsulo, nthaka TACHIMATA zitsulo mbale wotchedwa kanasonkhezereka mbale.
Gulu

Malinga ndi kupanga ndi processing njira akhoza kugawidwa m'magulu awa:
otentha kuviika kanasonkhezereka zitsulo pepala.Chitsulo chachitsulo chimamizidwa mumadzi osungunuka a zinki kuti amamatire chitsulo chopangidwa ndi zinc pamwamba.Pakalipano, amapangidwa makamaka ndi njira yopitilira galvanizing, ndiko kuti, mbale yophimbidwa yachitsulo imamizidwa mosalekeza mu thanki yopukutira momwe zinc imasungunuka kuti ipange chitsulo chosungunuka;
alloyed kanasonkhezereka zitsulo pepala.Chitsulo ichi chimapangidwanso ndi kuviika kotentha, koma ikangotulutsidwa, imatenthedwa mpaka pafupifupi 500 ° C kuti ipange filimu ya aloyi ya zinki ndi chitsulo.Izi kanasonkhezereka pepala ali adhesion wabwino ndi weldability wa ❖ kuyanika;
electro-galvanized steel plate.Kupanga pepala ngati kanasonkhezereka zitsulo ndi electroplating ali processability wabwino.Komabe, ❖ kuyanika ndi woonda ndi kukana dzimbiri si bwino monga kutentha kuviika kanasonkhezereka pepala;
plating yokhala ndi mbali ziwiri komanso zitsulo zosiyanitsa ziwiri.Single-mbali kanasonkhezereka zitsulo, ndiko kuti, mankhwala okha kanasonkhezereka mbali imodzi.Ili ndi kusinthika kwabwinoko kuposa pepala lokhala ndi mbali ziwiri pazowotcherera, kupenta, mankhwala odana ndi dzimbiri komanso kukonza.
Pofuna kuthana ndi zofooka za zinki zosatsekedwa kumbali imodzi, pali pepala lopangidwa ndi malata lomwe limakutidwa ndi nthaka yopyapyala ya zinki kumbali inayo, ndiko kuti, pepala losiyana lamitundu iwiri;
aloyi, gulu galvanized pepala.Amapangidwa ndi zinki ndi zitsulo zina monga aluminiyamu, lead, zinki, etc., kapena zitsulo zophatikizika.Chitsulo ichi chimakhala ndi kukana kwa dzimbiri komanso zinthu zabwino zokutira;
Kuwonjezera pa mitundu isanu yomwe ili pamwambayi, palinso zitsulo zamitundumitundu, malata osindikizidwa, ndi zitsulo za polyvinyl chloride laminated malata.Komabe, omwe amagwiritsidwa ntchito kwambiri akadali mapepala otentha a dip.
Miyezo yokhudzana ndi mankhwala imatchula makulidwe okhazikika, kutalika ndi m'lifupi zomwe zimalimbikitsidwa pamapepala opangidwa ndi malata ndi kulolerana kwawo.Nthawi zambiri, wandiweyani pepala kanasonkhezereka ndi, lalikulu kulolerana ndi, m'malo okhazikika 0.02-0.04 mm, kupatuka makulidwe alinso zofunika zosiyanasiyana malinga ndi zokolola, kumakoka koyeneka, etc. kutalika ndi kupatuka m'lifupi ndi zambiri. 5 mm, makulidwe a pepala.Nthawi zambiri pakati pa 0.4-3.2.
Pamwamba
(1) Pamwamba: Pepala lokhala ndi malata lili ndi njira zosiyanasiyana zochizira chifukwa cha njira zosiyanasiyana zochizira, monga duwa wamba la zinki, duwa labwino la zinki, duwa lathyathyathya la zinki, duwa lopanda zinki ndi phosphating.Miyezo yaku Germany imatchulanso milingo yapamtunda.
(2) Pepala lokhala ndi malata liyenera kukhala lowoneka bwino ndipo lisakhale ndi zolakwika zilizonse zovulaza monga kuyika, mabowo, ming'alu ndi zipsera, makulidwe ochulukirapo, zokopa, madontho a chromic acid, dzimbiri loyera, ndi zina. Miyezo yakunja siyimveka bwino. za zolakwika zomwe zimawonekera.Zolakwika zina zenizeni ziyenera kulembedwa pa mgwirizano poyitanitsa.
