Yuav ua li cas tiv thaiv cov galvanized txheej ntawm spcc - gi thaum lub sijhawm ua?
Lub galvanized txheej ntawm spcc - gi (kub}}} pa galvanized txias. Kev puas tsuaj rau txheej thaum ua (xws li khawb, tev, thiab oxidation) yuav cuam tshuam ncaj qha rau nws cov xeb tsis kam. Yog li ntawd, kev tiv thaiv kev ntsuas yuav tsum tau siv nyob rau hauv peb theem: pre -}}}} ™ optim optim - kev. Cov ntsiab lus yog raws li hauv qab no:
1. Ua ntej - kev ntsuas kev tiv thaiv kev ntsuas
Cov Khoom Siv Raw Khoom Cia Thiab Tuav
Zam kev puas tsuaj kev puas tsuaj: thaum lub sijhawm cia, cais txhua txheej ntawm cov ntoo hlau nrog cov ntoo lossis roj hmab mats kom tiv thaiv kev sib txhuam thiab khawb ntawm cov txheej los ntawm kev sib tsoo. Stacking qhov siab yuav tsum tau khaws cia rau qhov tsawg kawg nkaus (feem ntau tsawg dua lossis sib npaug nrog 1.5 meters) los tiv thaiv deformation ntawm cov nplooj hlau steel.
Kev tiv thaiv tiv thaiv ya raws thiab plua plav: txawm hais tias cov txheej txheem galvanized yog corrosion yog corrosion yog kev vaum siab yuav ua rau muaj xeb siab (zinc hydroxide). Khaws rau hauv lub tsev rau khoom qhuav thiab muaj cua rau cov tsev rau dej huv yog tias tsim nyog. Zam kev sib cuag nrog roj, av, acids, thiab cov hauv paus tiv thaiv kev xeb ntawm cov txheej. Tuav cov cuab yeej tiv thaiv: Thaum siv lub forklift lossis nqa cov khoom siv, roj hmab lossis cov ntaub qhwv nylon yuav tsum siv rau ntawm cov chaw uas tau sib cuag nrog cov hlau phaj. Tsis txhob siv hlau hooks rau ncaj qha nuv ntawm ntug ntawm cov hlau phaj kom tiv thaiv cov txheej los ntawm kev khawb los ntawm cov khoom ntse.
Pre6 -} Ua Tu
Yog tias muaj hmoov av los yog roj rau ntawm cov hlau phaj, so nws nrog cov dej huv (xws li qhuav kom tiv thaiv cov txheej txheem kom huv si los yog ua rau pwm hnav, uas tuaj yeem ua rau cov txheej ua kom ncaj.
Ii. Cov txheej txheem optimization thaum lub sijhawm ua (cov kauj ruam tseem ceeb)
Kev tiv thaiv cov txheej txheem stamping
Tuag Tsim Thiab Lubrication:
Tuag txiav cov npoo yuav tsum polished du (roughness ra tsawg dua los yog sib npaug rau 0.8μm) los tiv thaiv cov npoo ntse los ntawm kos txheej. Qhov kev tshem tawm ntawm kev tuag thiab xuas nrig yuav tsum yog me ntsis loj dua li ntawd ntawm dist distacy (feem ntau 5%{{65}} 10%) kom txo qis extrusion txhuam. Lubricants tshwj xeeb rau cov ntawv galvanized (xws li cov roj ntxhia los ntawm cov txheej txheem qhuav los ntawm kev ua kom qhuav los ntawm stamping) los ntawm kev ua rau oxidation thiab tshem tawm ntawm txheej. Cov kua roj acidic lossis alkaline acidic lossis alkaline cov roj nplua los yog txwv tsis pub tiv thaiv corrosion ntawm lub galvanized txheej.
Stamping txheej txheem tsis:
Txo cov stamping nrawm nrawm (tshwj xeeb tshaj yog rau kev sib sib zog nqus - cov duab kos nrog cov duab sib txhuam ntawm cov khoom thiab tuag. Kev tswj hwm stamping kub: yog tias cua sov yuav tsum (xws li thaum lub sij hawm kub yaj), khaws cia kom tsis txhob melting thiab poob ntawm txheej.
Shearing thiab dabtsi yog khoov
Cov Cuab Yeej Cuab: Siv Siab - ceev steel lossis carbide txiav cov cuab yeej los tiv thaiv cov cuab yeej tsis muaj txheej txheem. Thaum lub sij hawm shearing, lub cuab yeej clearance yuav tsum phim cov ntawv tuab (feem ntau 5% -10% ntawm daim ntawv tuab) kom txo qis kev extrusion thiab tev ntawm txheej. Kev tiv thaiv kev tiv thaiv:
Kev khoov cov vojvoog yuav tsum muaj ntau dua los yog sib npaug rau 1.5 zaug ntawm cov phaj tuab (cov ntaub qhwv qis dua li cov khoom siv hluav taws xob qis dua li cov khoom khoov ntau dhau lawm).
Pre6 - roj nplua nyeem tuaj yeem siv rau cov kev sib tw, lossis cov yeeb yaj kiab polytetrafene (ptfe) zaj duab xis los txo kev sib txhuam puas.
Kev Tiv Thaiv Vuam Kev Tiv Thaiv
Vuam hom: chaw vuam (Kuj yog vuam) yog qhov nyiam kom tsis txhob muaj kev puas tsuaj zinc los ntawm kev puas tsuaj zawv zawg rau arc vuam (xws li lo arc vuam). Yog tias muaj arc vuam yog qhov yuav tsum tau, siv tshwj xeeb galvanized steel hlau (muaj deoxidizing hais tawm (qis dua li cov phiaj xwm hlau) kom txo qis zinc evaporation thiab txheej poob.
Weld chaw kho: tom qab chaw welding, zinc txheej ncig weld yuav oxidize (blacken). Siv tus hlau stainless hlau txhuam kom maj mam muab tshem cov oxidation txheej. Thov lub siab - Zinc Kho Xim (xws li cov tshuaj tsuag txias txias txias (xws li kho cov txheej ua kom puas. Tuav thiab muab tso rau
Thaum hloov pauv cov paib hlau thaum ua cov hnab looj tes ntxuav cov hnab looj tes kom tiv thaiv hws kom tsis txhob hws (muaj cov ntsev) los ntawm corroding cov txheej. Tsis txhob rub cov phiaj hlau; Tsa lawv kom tiv thaiv khawb ntawm cov pa tawm tsam cov haujlwm saum npoo.
Lub chaw tiv tauj ntawm txoj kev Toolinging yuav tsum yog ua los ntawm cov ntaub ntawv mos xws li roj hmab thiab nylon kom tiv thaiv txoj cai tuav ntawm cov hlau.
III. Post {{{}} Kev Ua Tau Kev Kho thiab Kev Tiv Thaiv
Nrhiav kev puas tsuaj thiab kho
Tom qab ua tiav, tshuaj xyuas cov txheej txheej. Yog tias pom me me tau pom (tsis muaj qhov tshwm sim hauv qab), kho lawv nrog cov kab nrib pleb lossis zinc cov ntsiab lus ntawm ntau dua lossis sib npaug rau 95%. Yog tias khawb nthuav tawm qhov chaw dub ua ntej, ntxuav cov tsho tiv no epoxy (xws li epoxy primer) thiab txias epoxy primer los tiv thaiv xeb los ntawm corrooring lub substrate.
Rau cov cheeb tsam loj ntawm cov txheej txheej poob (xws li cov cheeb tsam uas muaj stormation ntau heev), ntsuam xyuas seb qhov tsim nyog, yog tias tsim nyog, hloov cov hlau phaj los tiv thaiv kev kis tus xeb. Kev Cia thiab Kev Tiv Thaiv Tsheb Thauj
Tom qab ua, semi {{- Cov khoom tiav yuav tsum tau qhwv nrog cov ntawv sau los yog VCI daim ntawv los tiv thaiv cov txheej los ntawm kev raug khawb los ntawm kev tawm mus. Yog tias lawv xav tau muab khaws cia rau lub sijhawm ncua sijhawm, txheej txheej nyias nyias
Thaum lub sij hawm thauj mus los, cais cov khoom sib cais nrog cov partitions los tiv thaiv kev sib txhuam thiab kev sib tsoo, thiab nteg roj hmab los tiv thaiv ya raws.
Ntsiab lus ntawm cov ntsiab cai tseem ceeb
Tus yuam sij tiv thaiv cov galvanized txheej ntawm spcc - gi lus dag, zam kev ua kom sov, thiab cais cov corrosive media "**:
Tswj chaw cia khoom tso cai ua ntej ua kom tiv thaiv kev puas tsuaj ntxov rau cov txheej;
Txhim kho cov pwm, lubrication, thiab txheej txheem tsis ua haujlwm thaum ua kom tsawg dua kev puas tsuaj tshuab thiab siab {}} kub oxidation;
