Q1: Dab tsi yog lub hauv paus ua rau txheej txheej puas thaum lub sij hawm nias cov txheej txheem ntawm cov xim -coated steel ntawv?
Txheej kev puas tsuaj thaum lub sij hawm nias qhov tseem ceeb stems los ntawm cov neeg kho tshuab kev nyuaj siab los yog ua kev puas tsuaj tshaj lub txheej lub cev txwv. Qhov no tuaj yeem muab faib ua peb hom:
Tensile / Compression Failure: Qhov no yog qhov tshwm sim ntau tshaj plaws. Thaum daim ntawv raug khoov hnyav lossis ncab thaum nias, yog tias cov txheej txheem nws tus kheej tsis muaj qhov yooj yim txaus (feem ntau soj ntsuam hauv kev lag luam los ntawm T-khoov kuaj), tawg, tawg, lossis loj - thaj tsam tev yuav tshwm sim, nthuav tawm cov substrate.
Kev puas tsuaj los yog khawb: Yog tias cov txheej txheem nias ntawm cov cuab yeej nias tsis du, muaj cov khawb tawv los yog hnav, cov khoom txawv teb chaws nyuaj xws li chips thiab hlau hmoov los ntawm cov ntawv tuaj yeem raug nias rau hauv txheej, uas yuav ua rau khawb, qhov, thiab lwm yam kev puas tsuaj ntawm lub cev ncaj qha rau ntawm txheej txheej.
Substrate Deformation Transmission Failure: Yog hais tias lub substrate nws tus kheej muaj qhov tsis xws luag (xws li ua tsis tiav galvanization lossis pitting ntawm lub substrate), deformation thaum nias yuav ua rau cov txheej ntawm cov ntsiab lus tsis muaj zog no poob kev txhawb nqa thiab "bulge," thaum kawg ua rau tawg.
Q2: Dab tsi tshwj xeeb ua rau txheej txheej puas thaum molding?
Los ntawm qhov kev xav ntawm tag nrho cov kev tswj xyuas zoo (TQM), qhov ua rau molding puas tuaj yeem raug soj ntsuam raws li hauv qab no:
Qeb|Tshwj xeeb ua rau|Ntsiab lus
Khoom siv (Material)|Tsis txaus txheej yooj / adhesion, ntau txheej txheej thickness los yog tsis zoo curing, tsis xws luag nyob rau hauv lub substrate nws tus kheej|Kev ua haujlwm tsis zoo ntawm txheej txheej, dhau - ci, lossis qhov tsis xws luag hauv substrate nws tus kheej yog lub hauv paus ua rau
Khoom siv (tshuab)|Kev khawb tawv / hnav / xeb ntawm lub siab rollers, kev hloov tsis raug ntawm qhov sib txawv ntawm cov menyuam sab sauv thiab qis qis, cov khoom siv tsis zoo levelness|Lub siab tsis zoo rollers yog lub cev ncaj qha ua rau khawb
Txheej txheem (txoj kev)|Khoov vojvoog me me dhau lawm, sib sau nrawm nrawm, tsis tsim nyog rau cov menyuam sib txawv, tsis zoo lub rooj tsavxwm tu|Kev teeb tsa tsis zoo yog tus yuam sij rau txheej txheej tawg
Q3: Yuav ua li cas xaiv thiab teeb tsa cov txheej txheem los tiv thaiv txheej thaum molding?
Cov txheej txheem scientific tsis yog lub hauv paus ntawm kev tiv thaiv txheej. Cov parameter tseem ceeb yog raws li nram no:
Khoov vojvoog (R lub kaum sab xis): Qhov no yog qhov tseem ceeb hauv kev txiav txim siab seb lub txheej puas yuav tawg. Lub hauv paus ntsiab lus tseem ceeb hauv cov txheej txheem yog tias lub vojvoog dabtsi yog khoov yuav tsum tsis pub tsawg dua ob npaug ntawm cov ntawv tuab (piv txwv li, rau 0.5 hli xim -coated daim ntawv, qhov tsawg kawg yog dabtsi yog khoov vojvoog yuav tsum tsis pub tsawg tshaj 1 hli). Qhov me me dhau ntawm lub vojvoog dabtsi yog khoov yuav ua rau cov txheej txheej elongation mus deb tshaj nws qhov kev zam.
Moulding ceev: Ntau moulding ceev, tshwj xeeb tshaj yog rau cov duab nyuaj, yuav ua rau kom muaj kev ntxhov siab ntawm cov txheej thiab kev pheej hmoo ntawm tev. Qhov tsim nyog thiab ruaj khov molding ceev yuav tsum tau teem raws li cov khoom siv thiab cov yam ntxwv ntawm daim ntawv.
Cov cuab yeej tshem tawm thiab kev huv: Nws yog ib qho tsim nyog los xyuas kom meej tias qhov sib txawv ntawm lub siab chais yog precisely matched rau daim ntawv thickness. Nyob rau tib lub sijhawm, txhua qhov chaw nyob rau hauv kev sib cuag nrog cov txheej txheem (xws li lub siab rollers thiab pwm) yuav tsum huv si, tsis muaj xeb thiab cov khoom tawv kom tsis txhob khawb cov txheej.
Q4: Yuav ua li cas los txiav txim seb qhov kev ua tau zoo ntawm cov xim -coated steel ntawv yog raws li tus qauv ua ntej molding?
Ua ntej loj molding, cov hauv qab no yuav siv tau los xyuas kom meej cov khoom zoo:
Thov thiab txheeb xyuas "Quality Certificate": Tau txais daim ntawv pov thawj khoom zoo los ntawm cov xim -coated steel sheet tsum. Ua kom pom tseeb ntawm ob lub ntsiab lus tseem ceeb: "T- khoov kev ua tau zoo" (kev ntsuam xyuas txheej yooj yim) thiab "txheej txheej adhesion" (xws li kev sib txuas ntawm lub zog ntawm cov txheej thiab substrate). Qhov qis dua T- khoov ntsuas, qhov yooj yim dua.
Ua ib qho "cov qauv molding": Rau cov haujlwm tseem ceeb lossis kev ua batch, txoj kev nyab xeeb tshaj plaws yog txiav cov qauv me me thiab sim-nias rau ntawm cov khoom siv ntau lawm siv cov txheej txheem txheej txheem. Ncaj nraim saib cov txheej txheem tom qab molding; qhov no yog txoj kev paub tseeb tshaj plaws thiab siv tau zoo.
Ua tib zoo saib xyuas cov txheej txheem tshwj xeeb: yuav tsum tau saib xyuas tshwj xeeb thaum siv siab - huab cua - tiv taus PVDF fluorocarbon txheej. PVDF txheej zaj duab xis yog mos; los tiv thaiv lawv thaum lub sij hawm thauj mus los thiab ua, nws yog feem ntau pom zoo los yog yuav tsum tau npog lawv nrog ib tug peelable pob tshab tiv thaiv zaj duab xis.
Q5: Kuv yuav kho cov txheej txheem puas tom qab molding?
Yog tias pom kev puas tsuaj hauv cheeb tsam tom qab molding, nws yuav tsum tau kho tam sim ntawd kom tsis txhob xeb ntxiv. Cov kauj ruam kho yog raws li nram no:
Ntxuav qhov chaw puas ntsoog: Siv daim ntaub huv kom tshem cov plua plav, roj, thiab cov xim xoob los ntawm qhov chaw puas.
Sanding (yeem): Rau thaj chaw uas muaj cov xim pleev xim, maj mam txhuam cov npoo kom zoo nrog cov ntawv xuab zeb zoo (xws li, 400 grit lossis siab dua) txhawm rau txhawm rau ua kom cov xim tshiab.
Siv cov tshuaj primer: Siv ib qho nruab nrab- kho zinc- nplua nuj primer los yog ceev- ziab xeb- cov xim tiv thaiv, ua tib zoo siv nws rau cov hlau nplaum uas muaj cov txhuam hniav zoo. Daim ntawv thov yuav tsum npog thaj tsam puas thiab nthuav tawm sab nraud los ntawm 5-10 mm.
Siv cov tshuaj pleev ib ce (yeem): Tom qab cov primer qhuav tag, yog tias cov xim sib xws, yuav tsum muaj xim kho tshwj xeeb (aerosol tuaj yeem lossis lub raj mis me) ntawm cov xim tib yam li pre-coated yob tuaj yeem siv rau kev pab them nqi.
