1.Vim li cas thiaj siv (galvanized) txias-rolled coils?
Lub zog thiab Rigidity: Daim npav qhov yuav tsum tau tiv thaiv qhov nro ntawm lub caij nplooj ntoos hlav thiab cua load. Txias-rolled coils yog nyias thiab flatter dua kub-rolled coils, thaum muaj lub zog txaus thiab nruj kom tswj tau lawv cov duab thiab tiv thaiv deformation.
Formability thiab Processability: Txias- dov coils muaj cov khoom sib xws, cov tuab tuab, thiab cov npoo du, ua rau lawv zoo tagnrho rau kev sib txuas txuas ntxiv. Cov ntoo khaub lig nyuaj- ntu cov duab ntawm daim npav qhov (xws li sab hauv- curled npoo thiab cov hlua txuas ntxiv) tuaj yeem tsim nyob rau hauv ib qho txheej txheem yob txoj kev ntawm cov kab sib dhos, uas ua rau muaj kev ua haujlwm siab heev thiab tus nqi qis.
Surface Quality thiab Corrosion Resistance: Qhov no yog qhov tseem ceeb tshaj plaws.
Bare txias-rolled steel (piv txwv li, dub hlau ntawv) yog heev yooj yim mus xeb thiab yog kiag li tsis haum rau cov av ib puag ncig ntawm tsev xog paj nrog qib siab ntawm chiv thiab tshuaj tua kab.
Zinc Plating: Ib txheej ntawm zinc yog plated rau saum npoo ntawm -rolled steel kauj. Cov txheej zinc no muab ob hom kev tiv thaiv:
Lub cev Barrier: cais cov hlau substrate los ntawm kev sib cuag nrog huab cua thiab noo noo.
Electrochemical Sacrificial Anode Protection: Txawm tias cov txheej txheej puas me ntsis, zinc (uas yog ntau reactive) yuav ua raws li cov anode, corroding ua ntej hlau, yog li tiv thaiv cov hlau hauv substrate. Qhov no ua rau nws cov kev tiv thaiv corrosion zoo dua li ntawm cov xim pleev xim.
Feem ntau siv cov txheej txheem galvanizing muaj xws li electro-galvanizing (uas ua rau lub teeb, ci, thiab nyias txheej) thiab kub-dip galvanizing (uas ua rau cov txheej tuab, muaj zog corrosion kuj, thiab lub neej ntev). Greenhouse card slots feem ntau siv kub-dip galvanized steel strips los xyuas kom meej lub neej kev pab cuam ntawm ntau tshaj 10 xyoo.
2.Dab tsi yog qee cov txheej txheem tsim khoom?
Cov khoom siv raw: Yuav kub-dip galvanized txias- dov steel coils (feem ntau ntawm 0.6mm thiab 1.2mm tuab).
Uncoiling thiab leveling: Unwind thiab leveling steel coils.
Nruam yob txoj kev: Hla lub steel sawb los ntawm ib tug series ntawm precisely tsim forming rollers, maj khoov nws mus rau hauv lub tsim qhov zoo. Qhov no yog txheej txheem tseem ceeb tshaj plaws.
Haum rau qhov ntev: Txiav cov qhov txuas txuas txuas ntxiv mus rau qhov ntev preset (xws li 4 meters, 6 meters).
Ntim thiab xa khoom: Qee qhov yuav raug qhov kawg -kev tiv thaiv xeb los yog raug ntim ncaj qha.
3.Yuav ua li cas piv rau aluminium alloys?
Tus nqi: Tus nqi ntawm galvanized txias- dov steel yog qis dua li ntawm aluminium alloy.
Lub zog thiab Elasticity: Hlau muaj ntau dua modulus ntawm elasticity, xav tau ntau zog los koom lub caij nplooj ntoos hlav tuav (feem ntau yog ua los ntawm lub caij nplooj ntoos hlav steel), ua rau muaj kev ruaj ntseg dua thiab tsis tshua muaj kev xoob. Aluminium alloy tuav lub nplhaib tuaj yeem hnov "mos."
Corrosion Resistance: Aluminium alloys kuj tuaj yeem corrode hauv alkaline xau lossis qee qhov chaw chiv. High-zoo kub-dip galvanized steel muaj lub neej ntev piv rau aluminium alloy, tab sis nrog tus nqi tseem ceeb.
4.Yuav ua li cas piv rau stainless hlau?
Stainless hlau muaj kev tiv thaiv corrosion zoo heev, tab sis nws cov nqi siab ua rau nws tsis yooj yim rau kev siv loj hauv tsev cog khoom.
5.Dab tsi yog cov ntsiab lus tseem ceeb thaum yuav khoom lossis tsim tsev cog khoom?
Substrate thickness: ncaj qha cuam tshuam rau load-cov kabmob muaj peev xwm thiab cua tsis kam.
Zinc txheej thickness/zinc cov ntsiab lus: Feem ntau hais nyob rau hauv "grams ib square meter" (xws li, Z80, qhia 80g / m² ob -sided zinc txheej) los yog "micrometers," uas ncaj qha txiav txim siab corrosion kuj lifespan. Kub-dip galvanizing yog qhov ruaj khov dua li electro-galvanizing.
Kev tsim cov txheej txheem: Cov pwm zoo tsim cov qhov nrog qhov ntev thiab cov npoo du uas yuav tsis khawb cov zaj duab xis.
