1.What yog kev ua yeeb yam ntawm kev txiav txheej tsis sib xws thickness?
Lub zinc txheej ntawm sawb nto yog cov tuab tuab heev (piv txwv li, "zinc accompulation" ntawm cov npoo) lossis dhau nyias. Thaum ntsuas nrog cov ntsuas cua sov, cov tuab tuab sile, feem ntau, DX53D +
Cov ua rau: tsis sib xws tswj ntawm "cov cua sib txawv" kev sib txawv ntawm cov npoo thiab qhov nruab nrab ntawm cov kab txaij thaum cov cua rab phom thaum cov cua tshuab hluav taws xob zinc); kev hloov pauv kub hauv cov laujk, uas ua rau hloov pauv hauv zinc flucide; Thiab tsis ruaj khov sauv nrawm nrawm (nrawm nrawm nrawm ua rau thinner zinc coast, qeeb qeeb nrawm ua rau tuab strips).
2.Qhov dab tsi yog cov kev tshwm sim thiab ua rau plating hla thiab tsis sib xws alloy txheej?
Cov tsos mob: cov txheej tsis tau ua tiav cov khaub ncaws zoo nkauj zinc {}}}}}}}}}}}}}}}} zn alloy theem). Qee thaj chaw ntawm cov ntshiab zinc nyob (xav tias du thiab yooj yim detached). Hloov pauv, cov txheej txheej txheej tuab yog qhov tsis sib xws, nrog cov chaw ntawm "grey {} {{- alloying) tshwm.
Cov ua rau: lub tshuab ua kom sov yog tsis muaj peev xwm lossis lub sijhawm cua sov luv heev (tsis tiav); Lub strip txias dhau lawm tom qab tawm ntawm zinc lauj kaub thiab ua ntej nkag mus rau cov hluav taws xob sib dhos (cov txheej zinc tsis ncav cuag (cov zinc Residual roj lossis oxide zaj duab xis ntawm sathet nto (uas cuam tshuam rau zinc {{}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}} econing hauv qee thaj chaw thiab sib sau "uas ploj mus").
3.Qhov yog dab tsi yog cov kev ua kom pom thiab ua rau cov zinc hais, zinc nti, thiab zinc ntws tawm?
Cov tsos mob: me me, tsa "zinc cov lus" (0.5-} 2 hli hauv saum npoo ntawm txheej; lossis ib cheeb tsam, thaiv, tsa "zinc nti" tshwm sim; thiab sawb-puab "Zinc Flow Marks" (zoo ib yam li cov dej stains) tshwm rau ntawm sawb nto raws li kev khiav.
Cov laj thawj: Qinc purity nyob rau hauv zinc lauj kaub (ntau dhau impurities xws li fe thiab pb, ua zinc slag uas ua rau cov sab sawb); tsis tiav degreast / Rust tshem tawm ntawm sawb ua ntej nkag mus rau cov hmoov zinc (residual hlau hmoov thiab roj nyob rau saum npoo muaj nrog cov nplais uas impurity sau); Los yog scum ntawm zinc lauj kaub deg sab saum toj tsis ntxuav, ua rau cov sawb tau nqa mus rau hauv txheej.
4.Yog dab tsi yog cov tsos mob thiab ua rau tsis yog -} plating (sprated hlau)?
Cov tsos mob: me ntsis daim hlab ntawm "raug hlau" (lub hauv paus hlau nthuav tawm thiab pom nyiaj {} grey) tshwm rau ntawm sawb nto. Zinc tseem nyob hauv cov chaw no, ua rau lawv raug rau xeb.
Cov laj thawj: Nto Oxidation thaum lub sijhawm muaj kev sib tw socos (cov ntsiab lus tiv thaiv tsis txaus nyob rau hauv sataling rauv, ntau dhau ntawm cov duab yeeb yaj kiab uas tiv thaiv zinc los ntawm adhering); Tsa lossis oxidized welds (thaum lub sij hawm vuam hlau uncoiled) ntawm txoj hlua hle Welds, tiv thaiv cov zinc los ntawm npog lub weld; Thiab tsis tiav ua ntej -}} Kev Kho Mob (Residual Dov Roj thiab teev rau ntawm qhov chaw hinder zinc Adhesion).
5.Qhov dab tsi yog cov kev ua kom pom thiab ua rau cov roj sib tw thiab oxidation xim?
Cov tsos mob: cov tsos mob steel nto yuav hnov cov roj (tawm hauv cov cim tom qab kov) lossis tuaj yeem tsim cov xim daj lossis xiav), cuam tshuam rau txheej txheej / vuam ntxiv.
Cov teeb meem: cov roj teeb tsis huv lossis cov roj tsis muaj txiaj ntsig (cov duab tuab ntau dhau los yog cov duab roj (xws li passivation (xws li passivation thiab roj); Cov qhuav tsis tiav ntawm lub sawb ua ntej coiling (seem ya raws ua rau cov xim hauv av); Los yog kev sib khi tsis zoo thaum lub sijhawm khaws cia ntawm cov coils tiav, ua rau muaj dej noo lossis ntev ua rau huab cua.
