1.How ua ntej kho ua ntej ua ntej zinc ntxiv?
Xeb tshem tawm
Rau xeb thiab teev rau ntawm qhov chaw puas, siv cov xuab zeb lossis xaim txhuam txhuam txhuam rau polish kom txog thaum lub hauv paus huv si.
Yog hais tias tus xeb yog tob, siv 10% dilute hydrochloric acid mus etch maj mam rau 3-5 vib nas this, tom qab ntawd yaug nrog dej huv thiab so kom qhuav los tiv thaiv cov kua qaub.
Degreasing thiab tu
So thaj tsam uas muaj cawv, acetone lossis cov ntiv tes tshwj xeeb (roj yuav ua rau cov kab zinc stains los poob tawm) thiab xyuas kom meej tias qhov chaw tsis muaj nplaum.
Kom qhuav: Siv cov cua compressed kom qhuav lossis qhuav lawm kom ntseeg tau tias qhov chaw qhuav tag nrho (noo noo yuav cuam tshuam rau kev kho kom huv lossis nplaum ntawm cov khoom siv zinc ntxiv).
2.What yog cov kev pab ntoo zoo tshaj plaws rau kev puas tsuaj rau me me, sab nraum zoov / sab hauv?
Cov tshuaj tsuag txias no: ib txheej zinc yog tsim los ntawm cov tshuaj tsuag txias
Cov txheej txheem kev ua haujlwm
Tom qab pretreaticment, siv rab phom tsuag lossis txau phom rau tusyees siv cov tshuaj tsuag txias kom huv si
Kho nyob rau hauv chav tsev kub rau 24 teev los ua ib qho zinc txheej nrog qhov sib xyaw zoo nrog thawj txheej galvanized txheej.
Cov txiaj ntsig zoo: yooj yim kev ua haujlwm, corrosion tiv thaiv ze rau kub-dip galvanizing, haum rau kev kho me me.
3.Qhov yog zinc ntxiv cov txheej txheem haum rau kev lag luam qib kev lag luam ntawm nruab nrab rau cov kev puas tsuaj loj-thaj chaw?
Lub hauv paus ntsiab lus: Zinc Hlau / zinc xinc / zinc hlau / zinc uas muaj hluav taws xob yog melted los ntawm hluav taws xob arc lossis nplaim taws thiab txau mus rau cov khoom siv ceev kom tsim lub zinc tuab.
Cov txheej txheem kev ua haujlwm
Sandblast thaj chaw puas (ncav cuag SA2.5 qib, Roughness nto 50-80μm) los txhim kho cov nplaum ntawm cov txheej zinc.
Siv Arc Zinc Zinc Txau Siv Lub Tshuab (High Efficiency) lossis nplaim taws zinc Txau rab phom (yoog raws lub molten zinc arely. Qhov deb (150-200mm) thiab nrawm ntawm rab phom txau yuav tsum tau tswj kom tsis txhob zinc txheej txuam lossis xiam kev txau.
Tom qab txau zinc, maj mam cheb cov nplaim nrog lub log xaim kom tshem zuaj zinc, thiab tshuaj tsuag ib zaug yog tias tsim nyog.
Cov txiaj ntsig zoo: Lub zinc txheej thickness yog tswj tau thiab muaj kev tiv thaiv zoo heev corrosion. Nws haum rau zinc ntxiv tom qab tiv thaiv vuam thiab thaj chaw loj-xeb kho (xws li Choj Cheebtsam).
4.Which zinc ntxiv txoj kev tsim nyog rau cov kev kho me me ntawm cov khoom siv precision?
Lub hauv paus ntsiab lus: electrolysis yog siv los tso zinc txheej ntawm thaj chaw puas, thiab cov tuab yuav tuaj yeem tswj tau meej
Cov txheej txheem kev ua haujlwm
Finely Nruaj thiab Degele qhov chaw puas, thiab siv insulating cov ntaub ntawv los npog thaj chaw uas tsis yog kho.
Siv cov kua qaub zinc plating electrolyte, siv zinc phaj raws li anode, tswj lub ntom ntom nti thiab lub sijhawm ua kom tiav cov txheej zinc.
Tom qab Electropating, yaug nrog dej huv kom tshem tawm cov khoom seem electrolyte, thiab ua kev kho passivation yog tias tsim nyog.
Cov txiaj ntsig zoo: Cov txheej zinc txheej thiab cov nplaim uas yog du, uas yog qhov tsim nyog rau kev kho cov tsev ua haujlwm (xws li cov vaj tse thiab cov sib txuas me).
5.Txhua kev khomob ib ntus thiab kev khomob xwmtxheej ceev, yuav ua li cas peb thiaj li yuav xaiv zincterement txoj kev ntxiv?
Zinc Thaiv / zinc Daim Riveting: Siv kev ua txhaum cai ntawm lub hauv paus ntsiab lus, zinc thaiv yog tsau ze ntawm thaj chaw uas puas nrog rivets. Cov zinc thaiv nyiam corrodes thiab tiv thaiv cov hlau.
Cov txheej txheem kev ua haujlwm: laum qhov nyob ib ncig ntawm thaj chaw puas thiab kho zinc thaiv (feem ntau yog 50 × 5 xyoos nrog zinc thaiv yog ze rau ntawm cov hlau.
Haum rau scenes qhov twg yuav tsis tau ua tam sim ntawd (xws li sab nraum zoov pipelines thiab cov qauv hlau loj) raws li kev ntsuas ib ntus.
Cov txiaj ntsig: Kev ua haujlwm nrawm, tsis tas yuav muaj cov cuab yeej nyuaj, haum rau kev kho mob xwm txheej ceev.
