Kuyanika dzenje
Mafotokozedwe Akatundu
Pambuyo kutsukidwa kwathunthu, zokutidwa ndi zigawozo ziyenera kuyikidwa kwathunthu mu njira yothandizira yosungunulira. Pambuyo kuziyika kwa mphindi 1-2, ziume.
Pepala lotenthetsera lotenthetsera limawumitsidwa ndi mpweya wotentha musanamizidwe, ndipo mpweya wotentha umayenda mosalekeza kunja kudzera muchipinda chowumitsa kuti ukhetse madzi a plating aid pamwamba pa plating.
Mpweya wotentha womwe ukuyenda mu dzenje lowumitsa uyenera kuyendetsedwa pa 100 ℃ - 150 ℃.
Nthawi yophika ya workpiece mu dzenje lowumitsa nthawi zambiri ndi mphindi 2 - 5. Pazigawo zokhala ndi zovuta, nthawi yophika imatsimikiziridwa molingana ndi kuchuluka kwa kuyanika kwa gawo I.
Chophimba chosunthika cha dzenje lowumitsira chiyenera kuyambika popanda zopinga. Pepala lamalati wotentha liyenera kuumitsidwa. Pambuyo potulutsidwa mu dzenje lowumitsira, liyenera kuviikidwa nthawi yomweyo kuti chogwiritsira ntchito chisanyowe pambuyo poyikidwa mumlengalenga kwa nthawi yaitali ndi chithandizo cha plating.
1. Malo okwanira adzasungidwa pamalo osungiramo zida zonyamulira.
2. Malo osungiramo mbale zachitsulo ndi zophimba zidzakonzedwa momveka bwino kuti zithandize kupeza ndi kuchepetsa kuyenda kosafunikira.
3. Chophimba chachitsulo chopingasa chidzayikidwa pa rabara pad, skid, bracket ndi zipangizo zina, ndipo chomangira chomangira chikhale chokwera.
4. Zogulitsazo ziyenera kusungidwa pamalo aukhondo komanso mwaudongo kuti zisawonongeke zamitundu yosiyanasiyana zowononga.
5. Pofuna kupewa kuphwanyidwa, mapepala opangidwa ndi malata nthawi zambiri amasungidwa kuti asungidwe, ndipo chiwerengero cha zigawo za stacking chiyenera kukhala chochepa.
Ntchito kutentha kwa galvanizing njira
- kutentha kwa Q235 yokutidwa workpiece udzalamuliridwa mkati 455 ℃ - 465 ℃
Mkati. Kutentha kwa Q345 yokutidwa workpiece adzakhala lizilamuliridwa mu osiyanasiyana 440 ℃ - 455 ℃. Pamene kutentha kwa zinki madzi kufika
Galvanizing sichidzayamba mpaka kutentha kwa ntchito kufikire. Kuteteza kutentha kudzachitika panthawi yotseka, kutentha kuyambira 425 ℃ mpaka 435 ℃.
