Galvanized steel yeeb nkab xeb

Galvanized steel yeeb nkab xeb yog tsuas yog rau zinc soluble nyob rau hauv acid thiab kuj yuav yaj nyob rau hauv alkali, yog li hu nws poj niam txiv neej hlau.Zinc nyob rau hauv cov huab cua qhuav yog yuav luag tsis muaj kev hloov.Nyob rau hauv huab cua ntub, zinc nto yuav tsim ib zaj duab xis ntom ntawm zinc carbonate.Muaj cov sulfur dioxide, hydrogen sulfide thiab marine cua, tsis zoo corrosion kuj ntawm zinc, tshwj xeeb tshaj yog nyob rau hauv kub thiab av noo huab cua uas muaj cov organic acids, zinc txheej yuav yooj yim corrosion.Zinc txheem electrode muaj peev xwm ntawm-0.76V, steel substrate, zinc txheej yog anodic txheej, uas yog siv los tiv thaiv corrosion ntawm hlau thiab hlau, qhov zoo thiab qhov tsis zoo ntawm nws cov khoom tiv thaiv ntawm txheej thickness kev sib raug zoo yog zoo.

Zinc txheej, passivation, staining los yog txheej tuav lub teeb tus neeg sawv cev, tuaj yeem txhim kho kev tiv thaiv thiab kho kom zoo nkauj.Zinc oxide nyob rau hauv cov huab cua, qhov chaw ntawm qhov tsim ntawm xeb dawb, qhov teeb meem no yog ib txwm.Nyob ntawm koj lub strip yog kub dip galvanized los yog electro-galvanized, kub dip galvanized, ces vim yog cov tuab tuab ntawm zinc los tsim cov xeb dawb tsis cuam tshuam rau ib txwm lav, vim tias oxidation tus nqi ntawm zinc hauv huab cua qeeb heev.Electro-galvanized tsis yooj yim hais.Tsis pom cov xeb yuav tsis cuam tshuam.Thaum koj xav kom txuag tau cov galvanized steel yuav tsum ceev faj tsis txhob muab ntub thiab kub huab cua qhov cua yog yooj yim heev rau pwm, qee lub caij ntuj no, ces ua raws li ntev dua.

Galvanized Steel Pipe kev xav tau

Rau kub dip galvanized steel yeeb nkab kev soj ntsuam zoo, qhov tseem ceeb tshaj plaws yog daim ntawv thov kev ua tau zoo ntawm galvanized steel yeeb nkab.
Lub ntsiab lus dabtsi yog khoov ntawm qhov kub dip galvanized yog hais txog qhov tshwm sim ntawm cov khoom siv hlau uas muaj cov khoom lag luam tawm los, qhov degree ntawm khoov ntawm cov qauv hauv cov hlau galvanized pib molding tseem ceeb heev, vim tias nws tuaj yeem kuaj cov yeeb nkab steel galvanized los ntawm sab nraud siab thaum cov tshuaj tiv thaiv. , yog tias qhov kev sim galvanized steel yeeb nkab siab qhov tseem ceeb, peb tuaj yeem ua kom tsim nyog qhov cuab lub zog galvanized steel yeeb nkab kom pheej yig dua raws li cov neeg siv khoom xav tau.
Yog hais tias lub hwj chim down tshwm sim, yuav tsum paub qhov txawv nruab nrab ntawm lub Upper thiab qis yield point.Lub ntsiab lus siab tshaj tawm yog cov qauv ua kom lub zog poob rau thawj zaug ua ntej qhov kev ntxhov siab tshaj plaws;qis yield point yog qhov kev ntxhov siab yam tsawg kawg nkaus thaum tsis suav nrog qhov pib hloov pauv, theem tawm los.Qhov ntsuas ntawm hardness hlau cov khoom los tiv thaiv cov khoom tawv indentation lub peev xwm ntawm qhov chaw, hu ua hardness.
Nyob ntawm cov txheej txheem kev sim thiab cov peev txheej ntawm qhov nyuaj tuaj yeem muab faib ua Brinell hardness, Rockwell hardness, Vickers hardness, Shore hardness, micro-hardness thiab high-temperature hardness.Feem ntau siv rau yeeb nkab Brinell, Rockwell, Vickers hardness.
