Cov kav hlau steel yog ib qho tseem ceeb hauv ntau qhov kev lag luam, nrog rau kev tsim kho, kev thauj mus los, thiab kev tsim khoom. Txhawm rau kom ntseeg tau tias cov kav dej steel yog cov kav ntev thiab tiv taus corrosion, lawv tau txais ntau yam kev kho saum npoo. Nov yog qee qhov feem ntau
KEV KHO SIAB:
1. Galvanizing: Cov txheej txheem no yog siv cov txheej txheem zinc rau saum npoo ntawm cov yeeb nkab steel. Galvanizing muab kev tiv thaiv zoo tiv thaiv corrosion, thiab nws yog feem ntau siv nyob rau hauv ib puag ncig hnyav.
2. Xim Txheej: Kev pleev xim yog lwm qhov kev kho mob nto moo rau cov kav hlau. Ntau hom xim tuaj yeem siv los tiv thaiv cov hlau los ntawm corrosion, xws li epoxy, polyurethane, thiab enamel. Txoj kev no muab cov txheej txheem tiv thaiv uas txhim kho kev zoo nkauj ntawm cov yeeb nkab.
3. Powder Coating: Hmoov txheej yog txheej txheem uas siv cov hmoov qhuav rau cov yeeb nkab steel nto. Cov hmoov yog ces rhuab, ua rau nws yaj thiab tsim ib tug tiv thaiv txheej. Cov txheej txheem no muab cov txheej txheem ruaj khov thiab ua kom ntev ntev uas tiv taus chipping thiab fading.
4. Phosphating: Cov txheej txheem no yog siv cov phosphate txheej rau cov yeeb nkab steel. Phosphating txhim kho cov hlau tsis kam tiv thaiv corrosion thiab txhim kho nws cov khoom adhesion, ua kom yooj yim rau cov xim los yog lwm yam ntaub ntawv.
5. Kev Txhaj Tshuaj Txhaum: Kev txhaj tshuaj blasting yog ib qho kev kho mob saum npoo uas siv cov cua kub siab los tawg cov khoom abrasive tawm tsam cov yeeb nkab steel. Txoj kev no tshem tawm cov kab mob ntawm qhov chaw thiab npaj qhov chaw rau txheej.
Los ntawm ntau yam kev kho mob saum npoo av muaj, cov kav hlau steel tuaj yeem tiv thaiv ntxiv los ntawm kev xeb thiab muab kev daws teeb meem ntev rau ntau yam kev siv.
KEV UA HAUJ LWM:
1. Txiav thiab Sizing: Cov kav hlau hlau tuaj txawv qhov ntau thiab tsawg, tuab, thiab qhov ntev, yog li lawv yuav tsum tau txiav thiab ua raws li qhov xav tau. Txoj haujlwm no yog ua los ntawm kev siv cov saws, plasma cutters, lossis cov nplaim taws, nyob ntawm qhov loj thiab tuab ntawm cov kav dej.
2. Vuam: Vuam yog qhov tseem ceeb hauv kev koom nrog ob lossis ntau dua cov kav hlau los tsim cov kav dej ntev dua lossis ib qho tshwj xeeb. Cov txheej txheem vuam sib txawv, xws li TIG, MIG, lossis welding, yog siv nyob ntawm qhov tuab ntawm cov kav dej thiab daim ntawv thov tshwj xeeb.
3. Polishing: Cov kav hlau feem ntau yuav tsum tau ua kom du thiab polished nto rau kev zoo nkauj lossis tiv thaiv corrosion. Polishing yog ua los ntawm cov ntaub ntawv abrasive, xws li cov ntawv xuab zeb lossis polishing pads, kom tshem tawm cov burrs lossis cov pob zeb ntxhib ntawm qhov chaw.
4. Txheej: Txheej yog tsim nyog los tiv thaiv cov kav hlau los ntawm corrosion, tshwj xeeb tshaj yog thaum lawv siv nyob rau hauv ib puag ncig hnyav. Ntau hom txheej txheej, xws li galvanizing, hmoov txheej, lossis epoxy txheej, tuaj yeem siv rau saum npoo ntawm cov kav dej kom muaj kev tiv thaiv zoo dua thiab ua haujlwm ntev.
5. Khoov: Qee daim ntawv thov yuav tsum tau cov kav dej steel yuav tsum tau khoov rau hauv cov duab tshwj xeeb lossis cov ces kaum. Txoj haujlwm no yog ua tiav los ntawm kev siv tshuab dabtsi yog khoov lossis mandrels kom ua tiav cov duab uas xav tau yam tsis muaj kev puas tsuaj rau kev ncaj ncees ntawm cov yeeb nkab.
6. Threading: Threaded steel kav yog siv rau hauv cov kav dej thiab cov pa roj ua kom cov kev sib txuas yooj yim dua. Threading yog ua tiav siv cov tshuab threading uas tsim cov xov ntawm qhov kawg ntawm cov yeeb nkab kom tso cai rau kev sib txuas yooj yim.
PACKING txoj kev ntawm cov yeeb nkab steel
1. Cov pob khoom:
Ib txoj hauv kev zoo tshaj plaws ntawm kev ntim cov yeeb nkab steel yog bundling lawv ua ke. Nyob rau hauv txoj kev no, ib pawg ntawm cov yeeb nkab steel yog khi ua ke siv cov hlua los yog hlau. Qhov no ua kom yooj yim tuav thiab khaws cov kav dej. Cov pob khoom yog muab qhwv nrog yas lossis lwm yam khoom siv tiv thaiv kom tsis txhob muaj kev puas tsuaj thaum thauj.
2. Ntoo Crates:
Ntoo crates kuj yog feem ntau siv rau steel yeeb nkab ntim. Cov kav dej tau muab tso rau hauv lub crates, thiab lub crate yog tom qab ntawd nrog bolts los yog screws kom ntseeg tau tias cov kav dej tsis txav thaum lub sijhawm thauj mus los. Cov crates feem ntau yog kab nrog cov khoom siv tiv thaiv kom tsis txhob muaj kev puas tsuaj rau cov kav dej.
3. Hlau Pallets:
Steel pallets yog lwm txoj kev nrov ntawm kev ntim cov kav hlau. Cov kav dej tau muab tso rau ntawm lub pallet steel thiab tom qab ntawd siv cov hlua khi lossis lwm yam khoom siv. Cov pallets tau muab tso rau sab saum toj ntawm ib leeg kom yooj yim thauj thiab khaws cia. Kev siv steel pallets xyuas kom meej tias cov kav dej tiv thaiv kev puas tsuaj los ntawm kev ya raws, xeb, thiab lwm yam sab nraud.
4. Cov ntaub qhwv yas:
Cov ntaub qhwv yas kuj tseem siv los ntim cov kav hlau. Nyob rau hauv txoj kev no, cov kav dej yog qhwv nrog yas los tiv thaiv lawv ntawm khawb, dents, thiab lwm yam kev puas tsuaj. Cov ntaub qhwv yas kuj tiv thaiv cov kav dej los ntawm kev qias neeg, uas yog qhov tseem ceeb, tshwj xeeb tshaj yog rau cov kav dej uas yuav siv rau hauv qhov chaw huv si.
