1.What yog vim li cas yog vim li cas qhov zoo ntawm galvanized Txheej Txheej Txheem tsis tau raws cov qauv?
Tsis txaus zinc coating tuab tuab: yog tias lub neej kev tiv thaiv kev ua haujlwm tsuas yog 30}}
Tsis zoo zinc txheej adhating: cov txheej txheej zinc yuav ua rau thaum thauj mus los lossis kev lag luam (xws li kev sib tw txias thiab ua kom tawg.
2.Qhov dab tsi yog cov nquag hom kev tsis xws luag hauv cov txheej txheem zinc?
Ploj lawm plating: feem ntawm lub substrate tsis duav nrog zinc, tsim "dub me ntsis." Cov chaw no yuav xeb uas xum (xim liab yuav tshwm nyob hauv 1-3 lub hlis).
Zinc cov lus / BURRS: Cov no yog tsa zinc thiab cov txheej zinc uas tuaj yeem yooj yim vim kev sib txhuam, ua rau thaj chaw me me ntawm substrate.
Pinholes: Me me qhov nyob rau hauv lub zinc txheej cia li noo kom nkag rau hauv qab, ua rau "subcutaneous corrosion" (qhov tshwm sim "subcutaneous corrosion" (tab sis cov substrate muaj xeb).
Ua rau: tsis khov zinc da dej kub thaum sov - kub galvanizing (ua rau cov kev tsis sib haum xeeb)
3.Qhov yog cov kev rau txim yog tias siv cov xwm txheej siv ntau dua qhov kev ua siab ntev tshaj ntawm cov galvanized txheej?
Lub Zinc Txheej nrawm nrawm, thiab thaj chaw loj ntawm cov xeb liab tshwm rau saum npoo.
Cov ntsev dawb paug tawm cov ntaub ntawv ntawm zinc nto, nrog cov xeb liab xeb (cov khoom siv hauv paus).
Cov pwm dub pom ntawm cov npoo zinc, thiab cov hauv paus khoom siv corrosion ua rau reddish {{0} xim av xeb residue.
4.Qhov dab tsi yog qhov tshwm sim ntawm cov ntawv tsis raug cai - txij nkawm?
Cov khawb saum npoo tsis txhob hais kom sai
Qhov Teeb Meem: Yog tias cov txheej zinc yog khawb thaum lub sijhawm thauj lossis teeb tsa lossis kev sib txhuam nrog cov khoom siv nyuaj (thiab cov xeb yuav kis rau cov txheej zinc ib puag ncig ("xeb kis").
Kev tu kom tsim nyog: hauv 24 teev ntawm khawb, kho nrog zinc cov ntsiab lus ntawm ntau dua los yog sib npaug nrog ovi anti- corrosion txheej. "
Ntev -} lub sij hawm stacking ua rau qhov cua tsis zoo
Qhov Teeb Meem: Galvanized cov khoom yog pawg ua tiav thiab khaws cia rau lub sijhawm ntev yam tsis muaj lub hnab ntim khoom lossis cov cua khoob. Qhov no tiv thaiv ya raws los ntawm kev tshaj tawm ntawm txheej, tsim "ib puag ncig huab cua" uas ua rau muaj xeb dawb ntawm lub substrate.
Galvanic Corrosion tshwm sim los ntawm kev sib cuag nrog lwm cov hlau
Qhov Teeb Meem: Yog Q345B Galvanized Coils tuaj rau hauv kev sib cuag ncaj qha (xws li tooj liab) thiab raug rau lub peev xwm loj dua, nrog cov khoom siv zinc ntau dua li cov khoom siv thiab corroding ua ntej, nrawm tsis ua haujlwm.
5.Qhov dab tsi yog cov lus qhia rau kev txhim kho thiab kho?
Zinc Txheej Txheej Muaj Teeb Meem:
Me me tsis xws luag (xws li nyob rau hauv ib cheeb tsam plating lossis nyias zinc txheej): Kho cov chaw me me nrog zinc hmoov xim; re - gallvanize cov chaw loj (muaj feem xyuam rau cov coilrocessed);
Kev tsis pom kev loj (xws li pinholes lossis thaj chaw loj ntawm cov khoom tsim nyog thiab zam kev siv nyob rau hauv cov kabmob lossis cov qauv sab nraum zoov.
Tshaj cov qauv hauv qee qhov chaw:
Raug rau cov muaj zog acids thiab alkalis / siab ntsev tsuag pleev xim (xws li siv cov ntaub ntawv fluorocal (xws li siv 304 stainless lossis huab cua hlau);
Cov chaw pa hluav taws xob: ntxiv qhov cua (xws li txhim kho cov kiv cua hauv cov roj av hauv cov yeeb nkab) thiab kuaj xyuas thiab tshem tawm noo noo los ntawm nplaim.
Tsis raug cai:
Scratches yuav tsum tau kho kom sai nrog zinc hmoov xim;
Khw cov ntaub ntawv stacked rau tsa cov platform / ntau dua los yog sib npaug rau 10 cm saum toj no av) thiab tawm 5 feem pua ntawm cov khaubncaws sab nraud pov tseg;
Cov ntaub ntawv insulate ntawm kev sib chwv nrog lwm cov hlau siv cov tshuaj insulating (xws li roj hmab lossis yas) kom tiv thaiv galvanic corrosion.
