1.How los ua kom zoo rau cov txheej txheem galvanizing?
Tswj cov tuab thiab qauv ntawm cov txheej alloy
Txo qhov kub ntawm cov lis dej zinc: tsis txhob kub siab dhau ntawm cov txheej tuab tuab tuab tuab, thiab tswj lub hom phiaj kub ntawm 440-455 degree.
Shorten The Sinc Systemers: Txo lub sijhawm tiv thaiv thiab txwv txoj kev loj hlob ntawm nkig loj Δ theem.
Txhim kho qhov nqi txias
Theem Xub: Tom qab plating, ua ntej txias qeeb (250-300℃rwb thaiv tsev) thiab tom qab ntawd txias nrawm kom txo qis kev ntxhov siab. Zam kev ua kom dej quenching: Cov dej txias kom ncaj qha yog nquag ua rau muaj kev cuam tshuam nrog cua sov, yog li cua txias lossis cua txias yog pom zoo.
2.How cov ntaub ntawv thiab tsim qauv raug txhim kho?
Xaiv lub siab-duction substrate: Muab qhov tseem ceeb rau cov hlau roj carbon thiab qis cov ntsiab lus kom tsis txhob muaj kev pheej hmoo ntawm cov khaub thuas txias.
Ua kom muaj kev khoov hluav taws xob hluav taws xob: qhov tsawg kawg nkaus khoov radius (r) ntau dua los yog sib npaug rau 3 zaug ntawm phaj tuab (t). Qhov loj dua r / t piv, txo qis kev pheej hmoo ntawm zinc txheej tawg.
Zam kev tsim qauv zoo nkauj: Siv Arc kev hloov hloov lub kaum sab xis (xws li r lub kaum ntse ntse tshaj lossis sib npaug) kom tsis muaj kev cuam tshuam rau kev sib txawv.
SLOTTING / Kev Siv Ua Ntej: Pre-Cut kev nyuaj siab ntxhov siab tua cov zawj uas muag ntawm qhov khoov kom txo qis kev deformation.
3.Qhov yuav tsum yog tus txheej txheem txias txias?
Sib zog ceev thiab deformation tus nqi
Tsawg-nrawm tsim: ceev tsawg dua los yog sib npaug rau 5m / min, kom tsis txhob muaj nkig tawg los ntawm kev kub ceev.
Multi-pass txoj kev sib tw zuj zus: ua kom tiav loj-ntawm khoov hauv cov kauj ruam (xws li 90 degree), ib qho deformation tsawg dua los yog sib npaug rau 30 degree.
Pwm Admression thiab Lubrication
Pwm Gap tswj: Sab saum toj thiab qis dua pwm kev sib tw {}} (1.03-1.08) t, dhau nruj yuav nyem cov txheej zinc txheej.
Polish Cov pwm nto: RA tsawg dua lossis sib npaug rau 0.4μm, txo kev sib txhuam kev puas tsuaj.
Siv cov roj nplua nyeem tshwj xeeb: cov roj nplua nyeem siab polymer (xws li txheej txheem ptfe) kom txo cov kev txhuam cov coefficient ntawm zinc txheej thiab pwm.
Kev Tswj Kub
Lub caij ntuj no preheing: thaum lub ambient kub yog<10℃, preheat the plate to 20-40℃ (such as infrared heating) to improve the toughness of the zinc layer.
Pwm Constant Kub: Tswj cov pwm kub ntawm 30-50℃los tiv thaiv tsawg-orgillion.
4.What yog cov kev xaiv txheej lwm yam?
Zinc-aluminium txheej: Mg ntxiv ntxiv kev txhim kho kev kho tus kheej kho kom zoo thiab nws cov cauj tawm tsam yog 3-5 lub sij hawm siab tshaj li ntawm cov ntshiab zinc.
Electroplating zinc: cov ntshiab zinc txheej muaj tsis muaj nkaws theem ib theem thiab muaj kev sib tw zoo heev.
Kev kho mob tom qab passivation: chromate passivation zaj duab xis puv microcracks thiab qeeb qhov pib ntawm corrosion.
5.Txhua kho li cas?
Cov kab tawg me (tsis muaj hlau nplaum): tshuaj lom zinc-txhuas txheej (xws li Zrc txias txias) txhawm rau cov kab nrib pleb.
Raug cov hlau txuas ntxiv:
Kho cov txheej txheem: Sandblasting (sa2.5) → Kev siv cov kab mob Topcoat: Seem ncaj qha kom tsis txhob muaj kev phom sij.
