S320GD hlau
S320GD steel chemical muaj pes tsawg leeg yog tailor- ua rau siab durability thiab corrosion kuj, thiab yog li zoo rau cov qauv siv. Nws feem ntau muaj cov pa roj carbon tsawg, manganese, phosphorus, thiab sulfur qib kom sib npaug ntawm lub zog thiab kev ua haujlwm. S320GD tau txhim kho cov khoom siv galvanization los ntawm zinc txheej, muab kev tiv thaiv ntau dua tiv thaiv ib puag ncig hnav thiab corrosion thaum piv nrog rau lwm qib steel xws li S235 lossis S355. Qhov tshwj xeeb thaj ntawm qhov zoo no muab nws ib txheej ntawm cov yam ntxwv uas ua rau nws muaj kev xaiv zoo hauv kev tsim kho thiab hauv kev tsim khoom.

- Cov ntsiab lus tseem ceeb:
Cov txheej tuab zoo txhim kho kev tiv thaiv corrosion, ua rau nws zoo meej rau kev xav tau sab nraum zoov.
Cov txheej txheem qis dua feem ntau yog xaiv rau kev siv sab hauv tsev lossis pleev xim rau qhov chaw, qhov kev tiv thaiv ntxiv tsis tsim nyog.
Cov txheej yog siv uniformly thaum lub sij hawm kub dip galvanization, kom ntseeg tau tias muaj kev tiv thaiv zoo ib yam nyob rau hauv cov hlau nto.
GNEE STEEL muajcustomized txheej xaivntsibkev xav tau kev lag luam tshwj xeeb, xyuas kom pom kev ua tau zoo hauvkev tsim kho, tsheb, thiab kev tsim khoom siv.
Kev kho saum npoo
Txhawm rau tiv thaiv kev tsim cov xeb dawb thaum thauj lossis khaws cia, cov kev kho mob hauv qab no muaj:
Tshuaj lom neeg (C)
Tshwj tsis yog tias pom zoo, zinc thiab Galfan coated coils thiab nplooj ntawv raug xa tawm raws li kev siv tshuaj lom neeg. Ib txheej nyias nyias tseem nyob ntawm qhov chaw ntawm cov khoom. Lub hom phiaj ntawm qhov no yog los tiv thaiv cov txheej txheem tiv thaiv kev tsim cov xeb dawb thaum lub sij hawm thauj mus los thiab khaws cia. Txoj kev kho no tsis txaus, txawm li cas los xij, rau kev tiv thaiv nyob rau hauv txhua yam mob.
Cov roj (O)
Yog tias xav tau, oiling tuaj yeem siv tsis siv tshuaj lom neeg passivation. Cov khoom siv hlau coated yuav tsum tau pleev xim rau yog pom zoo kom xa nyob rau hauv oiled mob thiab yog li ntawd Galvannealed coated coils raug xa raws li oiled, tshwj tsis yog tias pom zoo. Kev tiv thaiv corrosion ib ntus muab los ntawm cov roj tshwj xeeb yog nyob ntawm lub sijhawm khaws cia, thiab yog li lub sijhawm khaws cia ntev yuav tsum zam nrog cov khoom siv roj.
Chemical passivation thiab oiling (CO)
Passivation nrog oiling kuj muaj rau kev tiv thaiv ntau tshaj plaws.
Tsis muaj kev tiv thaiv (U)
Hauv cov xwm txheej tsis muaj kev tiv thaiv, piv txwv li yam tsis muaj kev kho saum npoo, muaj kev pheej hmoo rau kev tsim cov khoom siv corrosion thiab khawb thaum thauj, khaws cia lossis tuav. Cov khoom yog muab los ntawm qhov tsis muaj kev kho mob tsuas yog hais meej meej los ntawm cov neeg siv khoom ntawm nws tus kheej lub luag haujlwm.
