1.Inguva yakareba sei inogona kuperagalvanized coilkuchengetwa mudura?Sei?
A: Inobvumirwa kuchengetwa kwemwedzi mitatu kudzivirira oxidation inokonzerwa nekuchengetedza kwenguva yakareba.
2. Chii kureba kushiviriragalvanized steel sheet?
Mhinduro: Kureba kushivirira hakubvumirwi kuva nehuwandu husina kunaka, uye huwandu hahubvumirwi kudarika +6mm.
3. Chii chinonzi Zinc Flower spangle?Chii chinonzi spangle diki?Zero spangle?
Mhinduro: Iyo spangle hombe ndiyo yakajairika spangle.Zvinoenderana neyakajairwa kugadzirwa maitiro, iyo yakakura spangle inogona kugadzirwa.Iyo dhayamita yekristaro nucleus haisi pasi pe 0.2mm;iyo dhayamita yekristaro nucleus isingasviki 0.2mm, iyo inonzi diki spangle.Zvinoonekwa zvinoonekwa.
4. Chii chinonzi kudzivirira musimbotikupisa-kunyura kwakakurudziralayer?
Mhinduro: Nokuti zinc inogona kuumba firimu ine yakanaka corrosion resistance pamusoro penzvimbo inoparadza.Inodzivirira kwete chete zinc layer pachayo, asiwo nheyo yesimbi.
5. Ndeipi musimboti wekupfuura kwekoiri inopisa-dip galvanized?
Mhinduro: Iyo chromate passivation kurapwa kwegalvanized sheetinogona kuumba firimu rekuita, uye chimiro chayo chemakemikari chinotevera: Zn+H2GrO4-ZnGrO2=H2
Iyo trivalent chromium mumhinduro passivation mhuri hainyungudika mumvura, ikemikari isingaite, uye inoita seskeleton, nepo hexavalent chromium inonyungudika mumvura uye inogona kuita basa mukudzoreredza passivation kana firimu rekufambisa rakweshwa.Iyo ine mhedzisiro yekuporesa yepassivation firimu.Naizvozvo, mukati meimwe muganho, iyo passivation firimu inogona kudzivirira kukukurwa kwakananga kwepepa rakagadzirwa nemhepo kana mhepo inonyorova, uye zinc layer inobata basa rekudzivirira.
6. Ndedzipi nzira dzekuyedza kuomarara kwekuramba kwehot-dip galvanized sheet coil?
Mhinduro: Pane nzira nhatu dzekuyedza kuonda kwekushomeka kwepepa rinopisa-dhip: bvunzo yekupfapfaidza munyu;humidity test;irosion test.
7. Sei mushonga wekurwisa ngura uchifanira kuitwa pane zvinopisa-dip galvanized zvigadzirwa?
Mhinduro: Kana iyo inopisa-dip galvanized sheet iri mumhepo ine hunyoro, kunyanya kana mhepo ine acidic zvinhu zvakaita seSiO2, CO2, NO2 uye NO, pamusoro peiyo galvanized layer ichaita yakasununguka ngura chena.Izvo zvikamu zvikuru zvewhite rust ndeyeZnO uye Zn(OH) 2. Rudzi urwu rwekuchena rutsvuku haruiti chete chitarisiko, asi rinounzawo matambudziko makuru ekushandisa mune ramangwana.
8. Ndezvipi zvinokonzera ngura chena pagalvanized coil?
Mhinduro: Zvikonzero zvevhu chena ndezvi: inopisa-dip galvanizing inoiswa pamwe chete nezvimwe zvinopisa zvinopisa zvakadai seasidhi, alkali uye munyu;iyo passivation firimu kana anti-firimu yakakuvadzwa;iyo passivation kana kuzora mhedzisiro haina kunaka;dura rekuchengetedza harina mhepo yakanaka, Munyoro;galvanized sheet inopfapfaidzwa nemvura panguva yekufambisa;kutakurwa pakushisa kwakadzika uye kuchengetwa pakupisa kwepamusoro, zvichiita condensation.
