1.What cuam tshuam ua cov tuab tuab ntawm zinc txheej muaj rau ntawm lub hauv paus kev tiv thaiv kev tiv thaiv?
Hnav Zinc txheej: Muab cov ntsiab lus corrosion tsis kam thiab yog qhov haum rau qhuav / corrosive ib puag ncig. Nws yog tsawg {{{{1} tus nqi thiab tsawg dua qub rau tawg thaum ua rau cov tuab tuab tuab tuab.
Nruab Nrab - Qhov hnyav zinc txheej: muab cov corrosion tsis kam thiab tuaj yeem tiv taus me ntsis kev nyab xeeb thiab ib puag ncig huab cua dub / plua plav ib puag ncig. Nws cov nyiaj tshuav nqi thiab kev tiv thaiv, muab kev ua tau zoo.
Hnyav - Duty zinc txheej: {{1} {} {1} Cov ntug dej hiav txwv me me, thiab hmoov av. Nws muaj lub neej ntev ntev tab sis nyuaj me ntsis rau cov txheej txheem (tuab zinc txheej tuaj yeem tawg yooj yim thaum khoov).
Super - hnyav {{1} {{{overt {{2 {2 {2 {2 {{istor acid thiab alkali tsuag. Cov txheej txheej zinc yog tuab thiab ntom, xav tau cov txheej txheem tshwj xeeb (xws li preheating thiab dabtsi yog khoov).
2.Qhov dab tsi yog cov qauv kev teeb tsa thiab kev ua tau zoo ntawm cov ntshiab zinc txheej?
Txheej Txheem Nta: Cov Txheej Txheem Zinc yog ntshiab Zinc (ZN), lub cev txuas rau lub substrate (txias {{rolled hlau). Cov txheej zinc txheej yog cov mos mos thiab du tes, tab sis nws txoj kev sib sib zog ua nrog lub substrate yog ib nrab.
Tub Ntxhais Kev Ua Haujlwm:
Corrosion Kuj: cia siab rau "kev ua txhaum cai ntawm zinc" (zinc dorrodes lossis zinc hydrodes thiab zinc hydrodes thiab zinc hydrodes thiab zinc hydrodes thiab zinc hydrodes thiab zinc hydrodes thiab zinc hydrodes thiab zinc orrosionly
Kev ua haujlwm: zoo heev, haum rau kev sib sib zog nqus duab, ntau yam dabtsi yog khoov, thiab curling (xws li cov txheej txheem hauv tsev). Cov txheej dawb huv zinc yog mos thiab tsis muaj kev cuam tshuam kom tawg tau thaum muaj kev cuam tshuam.
DoGbacks: Yog hais tias cov txheej zinc yog puas thaum ua (xws li los ntawm cov khawb av stamping), nws yog nquag mus rau qhov chaw puas, uas xav tau kev tiv thaiv tom ntej. Qhov saum npoo kuj tseem siv rau "zinc sprangles" (crystalline qauv tsim thaum ntshiab zinc txias), xav tau kev kho mob ntxiv rau lub ntsej muag zoo nkauj.
3.Qhov yog tus yam ntxwv yog cov qauv thiab cov khoom tseem ceeb ntawm cov txheej zinc alloy?
Txheej Txheem Nta: Cov Paj Dawb Huv Zinc, raws li high - kub txheej (xws li fezn₇ txheej (Fe₂zn₁₀. Qhov no tsim cov hlau me me ntawm cov txheej zinc txheej thiab lub substrate, ua rau muaj kev sib raug zoo sib xyaw thiab tawv tawv zoo dua li ntawm zinc ntshiab.
Tub Ntxhais Kev Ua Haujlwm:
Corrosion Kuj: Lub Alloy Txheej Qhov Nruab Nrab Cov Nruab Nrab Kuj yog me ntsis
Kev ua haujlwm: Tsim nyog rau kev siv dabtsi yog yooj yim khoov thiab shearing, tab sis tsis yog rau kev sib sib zog nqus (cov txheej sib sib zog nqus yog qhov nyuaj thiab muaj zog tawg vim kev sib tsoo kom tob tob). Qhov saum npoo yog spangle - dawb, siab tiaj tus, thiab tuaj yeem raug tshuaj tsuag ncaj qha (tsis muaj ua ntej {2} Kev Kho Mob Yuav Tsum Tau).
Cov txiaj ntsig zoo: ntiv tes ua tus tiv thaiv (cov yeeb yaj kiab passivation yooj yim rau cov ntiv tes kom nruj me ntsis rau lub substrate) thiab kev txo qis tiam ntawm zinc vapor pores thaum vuam).
4.What yog cov nyhuv tsis ncaj ntawm zinc txheej rau lwm yam khoom?
Ua Kev Ua Tau Zoo: Ib txheej zinc uas yog tuab dhau los yog tiag tiag nkig yuav txwv cov kev xaiv.
Cov txheej dawb huv zinc (nyias mus rau nruab nrab): kev ua kom zoo, haum rau kev nqus tsev (xws li cov cuab yeej siv). Yog tias cov txheej zinc txheej dhau heev (ntau dua los yog sib npaug rau 275g / ㎡), nws yog nquag rau "Zinc sib tsoo tawg" thaum nws yuav tsum tau preheating.
Alloy Zinc Txheej: siab hardness, nquag ua rau "zinc hlawv, haum rau kev sib sib zog nqus tsev, thiab cov khoom siv tsis yooj yim sua thaum lub sij hawm vuam muag, thaum lub sij hawm alloy tsis muaj teeb meem no). Cov tsos pom ntawm lub ntsej muag: Lub zinc txheej txiav txim siab qhov ua tiav.
Cov txheej dawb huv zinc (nyias mus rau nruab nrab): nquag rau kev tsim ntawm "spangle" (cov qauv crystal). Rau ib tug "txim taws - pub dawb" dawb, kev kho mob ntxiv "(piv txwv li, tswj tus nqi txias). Cov txheej no muaj cov gloss siab thiab haum rau cov ntawv thov raug (xws li, cov khoom siv hluav taws xob).
Alloy Zinc Txheej: ib qho kev tso nyiaj nruab hnub {{grey} Cov kab txaij zoo nkauj, cov khoom ua kom haum raws li cov khoom siv hluav taws xob zoo nkauj Cov Zinc Txheej muaj zog nrog cov xim thaiv cov xim tiv thaiv cov xim ntawm fading. Tus nqi: Zinc Txheej Thickness thiab cov qauv ncaj ncaj fab cuam tshuam.
Thickness nqi: rau txhua txhua 50G / ㎡ nce rau hauv zinc txheej, tus nqi ib cheeb tsam nce ntxiv los ntawm kwv yees li 10%}}}}}}}}}}}}}}}}}}}} 15% (vim tias yog hloov pauv hauv Zinc Raw Cov Nqi). Yog li ntawd, tuab tuab yuav tsum raug xaiv raws li ib puag ncig cov cai (piv txwv li, sab hauv tsev cov ntawv thov tsis tas yuav tsum tau ua haujlwm zinc txheej hnyav).
Cov qauv tsim qauv: Alloyed Zinc Txheej Txheem yog 20% -30% kim dua li cov xim ntshiab Yog li ntawd, lawv tau nyiam rau cov ntawv thov ua kom muaj zog (xws li kev ua lag luam chassis) kom tsis txhob muaj tus nqi dhau los.
5.Qhov yog tus tub ntxhais tseem ceeb ntawm zinc txheej?
Ua ntej, xav txog qhov ib puag ncig: kev siv corrosion kev txiav txim siab txiav tawm Zinc Txheej Thickness.
Lub tsev nyob hauv tsev qhuav → hluav taws xob zinc txheej (40-80g / m2);
Ntub sab hauv tsev / semi- tawm sab nraud → tawm sab nraud → Cov Nruab Nrab Nruab Nrab Zinc Txheej Zinc (100-180G / M2);
Sab nraud sab nraud / ntug dej hiav txwv → Hnyav - duty} Dutying zinc txheej (200-350g / m2);
Kev tshuaj tsuag ntsev / muaj corrosion → ultra -} teatly zinc txheej (ntau dua lossis sib npaug nrog 400g / m2).
Tom ntej no, xav txog kev ua lag luam: Txoj kev tsim qauv txiav txim siab zinc txheej qauv qauv.
Txoj kev ua (kev kos duab sib sib zog nqus, ntau yam dabtsi yog khoov) → ntshiab zinc txheej (mos thiab ducast);
Kev ua tiav yooj yim (shearing, ib qho dabtsi khoov) + lub zog ua zog muaj zog (vuam, kev co) →ing zinc txheej (nyuaj thiab nruj thiab nruj nreem). Thaum kawg, sib npaug nqi: zam "overprotection." Piv txwv, sab hauv tsev cov ntaub li cas tsis tas yuav muaj 275g / ㎡ zinc txheej (khib nyiab ntawm tus nqi); Ib 100g / ㎡ Cov Dawb Dinc Txheej yog qhov txaus. Rau ntug dej hiav txwv
