Ndi mitundu ingati ya mapepala omatira omwe angagawidwe m'magulu malinga ndi njira zopangira ndi kukonza?

Mapepala opangidwa ndi galvanizedZingagawidwe m'magulu otsatirawa malinga ndi njira zopangira ndi kukonza:

(1)Chitsulo choviikidwa ndi galvanized chotenthaChitsulo chopyapyala chimamizidwa mu bafa yosungunuka ya zinc kuti chipange pepala lopyapyala lachitsulo lokhala ndi zinc yomatira pamwamba pake. Pakadali pano, ntchito yayikulu yopangira njira yopitilira yopangira ma galvanizing, ndiko kuti, mipukutu yachitsulo imamizidwa mosalekeza mu bafa yosungunuka ya zinc yopangidwa ndi chitsulo chosungunuka;

(2) chitsulo chopangidwa ndi galvanized. Mbale iyi yachitsulo imapangidwanso ndi kuviika kotentha, koma nthawi yomweyo ikatuluka mu thanki, imatenthedwa kufika pa 500 ℃, kotero kuti imapanga filimu yopyapyala ya zinc ndi alloy yachitsulo. Mtundu uwu wa pepala lachitsulo lopangidwa ndi galvanized uli ndi utoto wabwino komanso wosavuta kuwotcherera;

(3) Chitsulo chopangidwa ndi magetsi. Kupanga chitsulo chopangidwa ndi magetsi pogwiritsa ntchito njira yamagetsi kumakhala kosavuta kugwira ntchito. Komabe, chophimbacho ndi chopyapyala ndipo kukana dzimbiri sikwabwino ngati chitsulo chopangidwa ndi magetsi choviikidwa m'madzi otentha;

(4) Chitsulo cholimba cha mbali imodzi ndi mbali ziwiri chopanda chitsulo. Chitsulo cholimba cha mbali imodzi, ndiko kuti, cholimba mbali imodzi yokha ya chinthucho. Chimakhala chosinthika bwino kuposa chitsulo cholimba cha mbali ziwiri pankhani yolumikiza, kujambula, kuchiza ndi kukonza dzimbiri. Pofuna kuthana ndi zofooka za zinc yosaphimbidwa mbali imodzi, pali mtundu wina wa chitsulo cholimba chomwe chimakutidwa ndi zinc woonda mbali inayo, ndiko kuti, chitsulo cholimba cha mbali ziwiri chosiyana;

(5) Aloyi ndi pepala lachitsulo lopangidwa ndi galvanized. Limapangidwa ndi zinc ndi zitsulo zina monga aluminiyamu, lead, zinc ndi zitsulo zina zopangidwa ndi galvanized komanso chitsulo chopangidwa ndi galvanized. Mtundu uwu wa mbale yachitsulo uli ndi magwiridwe antchito abwino kwambiri oteteza dzimbiri komanso mawonekedwe abwino opaka utoto;

Kuwonjezera pa zisanu zomwe zili pamwambapa, palinso zitsulo zokongoletsedwa ndi utoto, zitsulo zosindikizidwa ndi zopakidwa utoto, zitsulo zokongoletsedwa ndi PVC, ndi zina zotero. Komabe, zomwe zimagwiritsidwa ntchito kwambiri pakadali pano zikadaliHot kuviika kanasonkhezereka mbale.

Maonekedwe a chitsulo cholimba
[1] Mkhalidwe wa pamwamba:Mbale Yopangidwa ndi KanasonkhezerekaChifukwa cha njira yophikira yomwe imagwiritsidwa ntchito m'njira zosiyanasiyana, mawonekedwe a pamwamba ndi osiyana, monga duwa la zinc wamba, duwa laling'ono la zinc, duwa la zinc losalala, duwa lopanda zinc, ndi chithandizo cha phosphate pamwamba ndi zina zotero. Muyezo wa ku Germany umatchulanso mulingo wa pamwamba.
[2] Pepala lopaka chitsulo liyenera kukhala ndi mawonekedwe abwino, sipadzakhala zolakwika zilizonse zomwe zingawononge kugwiritsa ntchito chinthucho, monga kusakhala ndi ma plating, mabowo, kuphulika, komanso slag, kuposa makulidwe a plating, kukwawa, madontho a chromic acid, dzimbiri loyera, ndi zina zotero.

① Kawirikawiri, mapepala okhawo opangidwa ndi galvanized, omangika komanso okoka mozama ndi omwe amafunika kuti akhale ndi mphamvu yokoka. Mapepala omangika ndi galvanized ndi omwe amafunika kuti akhale ndi mfundo yoti agwire ntchito, mphamvu yokoka ndi kutalika, ndi zina zotero; kukoka kumafuna kutalika kokha. Makhalidwe enieni onani "8" mu gawo ili la miyezo yoyenera ya malonda;
② njira yoyesera: mofanana ndi njira yoyesera yachitsulo choonda, onani "8" yoperekedwa ndi miyezo yoyenera ndi "pepala lachitsulo la kaboni wamba" lomwe lalembedwa mu muyezo wa njira yoyesera.

[2] Mayeso opindika:
Kuyesa kupindika ndiye pulojekiti yayikulu yoyesera momwe chitsulo cha pepala chimagwirira ntchito, koma miyezo yadziko lonse ya zofunikira zosiyanasiyana za chitsulo cha pepala cha galvanized si yofanana, muyezo wa US, kuwonjezera pa kalasi ya kapangidwe kake, zina zonse sizifuna mayeso opindika ndi omangika. Japan, kuwonjezera pa kalasi ya kapangidwe kake, kumanga chitsulo cha corrugated ndi pulasitiki wamba wa corrugated kupatula zina zonse zimafunika kuti apange mayeso opindika.

Kukana dzimbiri kwa pepala lopangidwa ndi galvanized kuli ndi zinthu ziwiri zazikulu:

1, ntchito ya chophimba choteteza
Pamwamba pa galvanized kuti apange filimu yokhuthala ya oxide

2, pamene pazifukwa zina zinki ikakanda, zinki yozungulira imagwiritsidwa ntchito ngati cation yoletsa dzimbiri la chitsulo.
