1. cov khoom siv feem ntau siv hauv cov txheej txheem hlau
Cold dov hlau
Cov khoom siv txias txias yog siv hauv kev tsim kho, kev lag luam teeb, khoom siv hauv tsev, electromechanical, tsheb thiab lwm yam lag luam.Cov khoom lag luam muaj cov yam ntxwv ntawm qhov raug siab ntawm cov duab thiab qhov ntev geometric, kev ua haujlwm ruaj khov ntawm tib lub yob, thiab zoo nto zoo.
SGCC
Tsis tshua muaj ntau yam khoom siv hauv tsev me me, qhov zoo li qhov zoo.Spangle cov ntsiab lus: ib txwm tsis tu ncua spangle thiab minimized spangle thiab nws muaj peev xwm paub qhov txawv ntawm nws txheej: piv txwv li, Z12 txhais tau tias tag nrho cov nyiaj ntawm ob sab txheej yog 120g / mm2.
SGCC kuj tseem muaj cov txheej txheem txo qis thaum lub sij hawm kub-dip galvanizing, thiab lub hardness yog me ntsis nyuaj, yog li cov stamping kev ua tau zoo ntawm cov ntawv hlau tsis zoo li ntawm SECC.Lub zinc txheej ntawm SGCC yog tuab dua li ntawm SGCC, tab sis nws yooj yim dua rau txheej txheem thaum zinc txheej yog tuab dua.Zinc raug tshem tawm, thiab SECC yog qhov tsim nyog rau qhov nyuaj stamping qhov chaw.
5052 Aluminium alloy
5052 aluminium alloy muaj qee qhov zoo tshaj plaws vuam cov yam ntxwv, muaj kev ua tiav zoo, muaj cov dej ntsev zoo heev, tab sis tsis yooj yim machined.Cov hlau no tseem tsis tuaj yeem kho cua sov thiab tsuas tuaj yeem ntxiv dag zog siv cov txheej txheem ua haujlwm-hardening, nrog 5052-H32 yog cov txheej txheem ntau tshaj plaws (kom paub ntau ntxiv txog kev ua haujlwm-hardening, xav tias dawb tuaj xyuas peb tsab xov xwm txog 5052 txhuas alloy. Hom 5052 txhuas kuj suav hais tias yog qhov muaj zog tshaj plaws ntawm cov hlau tsis muaj cua sov, vim li no, 5052 txhuas ua haujlwm tshwj xeeb zoo li cov ntawv thiab phaj hlau, sib txuas ua ke zoo heev thiab weldability nrog nce zog. Al. 5052 txhuas tsis muaj tooj liab, uas txhais tau hais tias nws tsis muaj kev cuam tshuam rau cov dej ntsev corrosion xws li lwm cov aluminium alloys, ua rau nws yog ib qho kev xaiv zoo tshaj plaws rau kev siv dej hiav txwv, nws kuj yog feem ntau siv hauv cov khoom siv hluav taws xob, cov khoom siv kos npe, cov hlab ntsha siab, thiab cov khoom siv kho mob.
Stainless hlau 304
SUS 304 yog lub hom phiaj dav dav hlau stainless uas tau siv dav los ua cov khoom siv thiab cov khoom siv uas yuav tsum tau muaj kev sib xyaw ua ke zoo ntawm cov khoom (corrosion resistance and formability).
Stainless hlau 316
SUS316 siv los tsim Cov Hniav, cov khoom siv kho tshuab, cov khoom siv roj av refining, bolts, txiv ntseej, twj tso kua mis, Chav Kawm 1 cov tais diav (cov tais diav thiab diav rawg)
2. Kev kho deg zoo rau cov ntawv hlau
Electroplating:
Kev siv tshuab ntawm kev tso cov hlau nplaum zoo nrog cov ntaub ntawv sib txawv matrix ntawm cov khoom siv tshuab los ntawm electrolysis.Cov txheej txheej electroplating yog ntau dua li cov txheej kub-dip, thiab feem ntau yog nyias, xws li los ntawm ob peb microns mus rau kaum ntawm microns.Los ntawm electroplating, kho kom zoo nkauj tiv thaiv thiab ntau yam kev ua haujlwm saum npoo txheej tuaj yeem tau txais ntawm cov khoom siv tshuab, thiab cov khoom ua haujlwm uas hnav thiab tshuab tsis raug kuj tuaj yeem kho.Tsis tas li ntawd, muaj cov haujlwm sib txawv raws li ntau yam kev xav tau ntawm electroplating.Ib qho piv txwv yog raws li nram no:
1. Copper plating: siv los ua primer los txhim kho qhov adhesion thiab corrosion kuj ntawm electroplating txheej.
2. Nickel plating: siv los ua primer lossis ua kom pom kev txhim kho corrosion thiab hnav tsis kam (ntawm lawv, cov tshuaj nickel yog hnav-resistant dua li chrome plating hauv cov cuab yeej niaj hnub).
3. Kub plating: Txhim kho conductive tiv thaiv thiab txhim kho cov teeb liab kis tau tus mob.
4. Palladium-nickel plating: Txhim kho kev tiv thaiv kev sib cuag, txhim kho cov teeb liab kis tau tus mob, thiab muaj kev hnav siab dua li kub.
5. Tin thiab txhuas plating: txhim kho lub vuam muaj peev xwm, thiab yuav sai sai no yuav hloov los ntawm lwm yam kev hloov (vim feem ntau ntawm cov txhuas tam sim no plated nrog ci tin thiab matte tin).
Hmoov Txheej / Coated:
1. Ib txheej tuab tuaj yeem tau los ntawm ib txheej.Piv txwv li, txheej txheej ntawm 100-300 μm yuav tsum tau coated 4 mus rau 6 zaug nrog cov txheej txheem hnyav, thaum lub thickness no tuaj yeem ua tiav nrog cov hmoov txheej ib zaug..Kev tiv thaiv corrosion ntawm txheej yog zoo heev.(Peb pom zoo kom koj ua tib zoo saib rau "Mechanical Engineer" pej xeem account, thiab paub txog kev paub txog cov khoom qhuav thiab cov ntaub ntawv kev lag luam kom sai li sai tau)
2. Cov hmoov txheej tsis muaj kuab lom thiab tsis muaj kuab paug ntawm peb qhov pov tseg, uas txhim kho kev ua haujlwm thiab kev nyiam huv.
3. Cov thev naus laus zis tshiab xws li hmoov electrostatic txau yog siv, uas muaj kev ua haujlwm siab thiab tsim nyog rau kev sib dhos tsis siv neeg kab painting;hmoov siv tus nqi siab thiab tuaj yeem rov ua dua.
4. Ntxiv rau cov thermosetting epoxy, polyester, acrylic, muaj ntau cov thermoplastic grease-resistant tuaj yeem siv los ua hmoov txheej, xws li polyethylene, polypropylene, polystyrene, fluorinated polyether, nylon, polycarbonate thiab ntau yam fluorine resin, thiab lwm yam.
Electrophoresis
Electrophoretic xim zaj duab xis muaj qhov zoo ntawm tag nrho, niaj hnub, tiaj tus thiab du txheej.Lub hardness, adhesion, corrosion kuj, cuam tshuam kev ua tau zoo thiab kev nkag mus ntawm electrophoretic xim zaj duab xis yog pom tseeb zoo dua li lwm cov txheej txheem txheej.
(1) Kev siv cov dej-soluble xim thiab dej raws li qhov nruab nrab dissolving yuav txuag tau ntau cov organic solvents, txo cov pa phem thiab ib puag ncig muaj kev phom sij, muaj kev nyab xeeb thiab huv si, thiab zam qhov kev phom sij zais ntawm hluav taws;
(2) Cov txheej txheem txheej yog siab, cov txheej poob yog me me, thiab kev siv cov txheej txheem tuaj yeem ncav cuag 90% txog 95%;
(3) Lub thickness ntawm txheej zaj duab xis yog zoo ib yam, lub adhesion yog muaj zog, thiab txheej zoo yog zoo.Txhua qhov chaw ntawm cov khoom ua haujlwm, xws li cov txheej sab hauv, kev nyuaj siab, welds, thiab lwm yam, tuaj yeem tau txais cov xim zoo nkauj thiab du, uas daws qhov teeb meem ntawm lwm txoj kev txheej txheej rau cov duab ua haujlwm nyuaj.txheej teeb meem;
(4) Kev ua haujlwm siab ntau lawm, tsis siv neeg txuas ntxiv tuaj yeem ua tiav hauv kev tsim kho, uas txhim kho kev ua haujlwm zoo;
(5) Cov cuab yeej siv tau yooj yim, tus nqi peev yog siab, kev siv hluav taws xob loj, qhov kub thiab txias yuav tsum tau ziab thiab kho yog siab, kev tswj cov xim thiab txheej yog complex, kev tsim kho yog nruj, thiab kev kho dej khib nyiab yuav tsum tau ua. ;
(6) Tsuas yog cov xim dej-soluble tuaj yeem siv tau, thiab cov xim tsis tuaj yeem hloov pauv thaum lub sijhawm txheej txheej txheej, thiab kev ruaj ntseg ntawm cov xim tom qab khaws cia ntev yog qhov nyuaj rau kev tswj.(7) Cov khoom siv electrophoretic txheej yog qhov nyuaj thiab cov ntsiab lus thev naus laus zis siab, uas tsim nyog rau kev tsim cov xim ruaj khov.
