Ib kilogram ntawm hmoov txheej tsis muaj qhov chaw ruaj khov.Hmoov ntom ntom, kho zaj duab xis tuab thiab siv cov khoom sivtxiav txim siab npaum li cas tau txais coated nto nws xa. Xim, kev ntxhib los mos, ib feem geometry, daim ntawv thov teeb tsa thiab cov hmoov rov qab cuam tshuam rau cov khoom siv.
Rau cov neeg yuav khoom, daim duab muaj txiaj ntsig yog qhov lees txais thaj chaw tau txais los ntawm txhua kilogram hmoov tau noj. Daim duab hais txog qhov kev pab cuam yuav pab tau thaum nws cov thickness, tiav thiab ntau lawm cov xwm txheej phim txoj haujlwm.
Xav tau kev kwv yees kwv yees rau koj qhov chaw?
Xa koj cov duab kos rau peb, yuav tsum tau ua tiav thiab lub hom phiaj zaj duab xis thickness.

Ib tug qauv rau hmoov txheej txheej
Siv cov qauv no los kwv yees qhov chaw txais coated ib kilogram:
Kev pab them nqi (m²/kg)=(1,000 × η) ÷ (ρ × t)
- ρyog cov hmoov xaiv cov khoom ntom ntom hauv g / cm³. Siv qhov ceev hauv nws daim ntawv qhia kev, tsis yog xoob lossis tapped bulk ntom.
- tyog thaj tsam-hnyav txhais tau tias kho cov zaj duab xis qhuav tuab hauv μm thoob plaws qhov chaw coated.
- ηyog qhov sib koom ntawm net hmoov noj uas dhau los ua txheej ntawm qhov lees txais, nkag mus ua tus lej. Piv txwv li, 85% yog nkag li 0.85.
Teem rau1kom tau txais kev pov hwm theoretical ua ntej cov khoom poob. Rau kev kwv yees siv tau, siv daim duab siv ntsuas ntawm ib txoj haujlwm sib piv. First-pass hloov efficiency ib leeg tsis sawv cev rau qhov kawg siv zaj duab xis zoo thaum cov hmoov zoo thiab rov qab siv dua.
Piv txwv:Nrog ib tug assumed ceev ntawm1.50 g / cm³, kho zaj duab xis thickness ntawm80 μmthiab zoo-film siv ntawm85%, kev pab them nqi zoo yog kwv yees li7,08 m²/kg. Nyob rau tib qhov ceev thiab thickness, qhov theoretical txwv yog8.33 m² / kg.
Cov tswv yim no qhia txog txoj kev. Lawv tsis ntsuas specifications los yog guaranteed yields rau Chengwei khoom. Confirm the selected grade's density and approved film build, then validate consumption on representative parts. Rau cov yeeb yaj kiab textured, siv txoj kev ntsuas qhov pom zoo thiab tshawb xyuas qhov kwv yees tawm tsam kev siv cov khoom siv tiag tiag.
Dab tsi cuam tshuam rau hmoov txheej?
Kho zaj duab xis thickness
Cov txheej tuab dua siv cov khoom siv ntau dua nyob rau tib cheeb tsam. Ntawm qhov ntom ntom ntom ntom, nce zaj duab xis thickness los ntawm60m mus 80msiv txog33% ntau hmoov rau ib square meter, ua ntej cov txheej txheem poob.
Tswj thickness thoob plaws tag nrho cov tivthaiv. Kev nyeem ntawv txaus siab nyob rau hauv qhov chaw so tsis pom tias cov ntsej muag sab nrauv tuaj yeem raug overcoated. Xyuas lub ntsej muag tiaj tus, npoo, welded seem thiab cov ces kaum nyuaj tiv thaiv qhov pom zoo specification.
Txo cov yeeb yaj kiab thickness txhim kho kev tiv thaiv tsuas yog thaum nkaum, qhov tsos thiab qhov xav tau kev ua haujlwm tseem tuaj yeem siv tau. Tsim kom muaj kev pom zoo zaj duab xis-tsim ntau yam ua ntej muab cov hmoov sib piv.
Hmoov ceev, xim thiab zais
Cov hmoov uas muaj cov khoom sib txawv sib txawv muab qhov sib txawv theoretical ntawm tib lub thickness. Resin, pigments, fillers thiab cov ntaub ntawv muaj txiaj ntsig cuam tshuam qhov ntom ntom, yog li tus nqi ntawm ib qho xim yuav tsum tsis txhob siv rau lwm tus.
Xim kuj cuam tshuam rau zaj duab xis xav tau los nkaum lub substrate. Paub meej tias nkaum ntawm cov khoom siv hauv paus thiab pretreatment. Ib qho kev siv RAL qhia txog lub hom phiaj xim; nws tsis txhais cov hmoov ntom ntom, opacity lossis thaj chaw txau.
Ib feem zoo thiab khib loading
Cov vaj huam sib luag loj loj, cov khoom siv hlau thiab cov khoom siv welded nthuav tawm cov hom phiaj sib txawv rau cov huab cua. Cov kab sib sib zog nqus, folded rov qab thiab cov ces kaum sab hauv tuaj yeem nyuaj rau cov txheej txheem sib npaug. Qhov dav dav ntawm cov khoom dai tso cai rau cov hmoov ntau dhau mus yam tsis muaj kev tso nyiaj.
Ntsuas qhov saum npoo uas xav tau txheej txheej, suav nrog lub ntsej muag rov qab, cov npoo thiab rov qab. Zuag qhia tag nrho ntev thiab dav ntawm ib qho khoom sib dhos tuaj yeem understate nws coated cheeb tsam.
Daim ntawv thov kev teeb tsa thiab hmoov txheej
Phom txoj hauj lwm, tshuaj tsuag qauv, cov zis hmoov, airflow thiab electrostatic chaw cuam tshuam rau deposition. Kev ntseeg tau hluav taws xob tiv tauj los ntawm cov hangers kuj tseem ceeb. Kho cov txheej txheem rau cov khoom siv tiag tiag uas siv cov khoom siv khoom siv cov lus qhia ua haujlwm.
Moisture, contamination, tsis ruaj tsis khov fluidization thiab ib qho tsis sib xws ntawm cov nkauj xwb / cov khoom siv rov qab tuaj yeem cuam tshuam cov hmoov xa tuaj thiab ua tiav zoo. Kev tsim cov hmoov nplej ntau ntxiv tuaj yeem tsim cov tshuaj ntau dhau yam tsis muaj kev daws teeb meem tsis sib xws. Sau cov kev sim teeb tsa kom muaj kev sib piv siv tau rov ua dua.
Deg kev ntxhib los mos thiab txheej txheej
Smooth, satin thiab txiv kab ntxwv-kev ntxhib los mos finishes xav tau lawv tus kheej pom zoo tsos thiab zaj duab xis-tsim checks. Ib tug textured hmoov yuav tsum tsis tau txais kev pab them nqi los ntawm ib tug du-panel mus sib hais.
Substrate roughness thiab tus naj npawb ntawm cov khaubncaws sab nraud povtseg kuj cuam tshuam rau kev noj. Yog tias txoj haujlwm xav tau primer thiab topcoat, ntsuas ob txheej. Daim duab npog rau topcoat ib leeg tsis tuaj yeem piav qhia tag nrho.
Hmoov rov qab thiab pov tseg tus nqi
Overspray tsis tuaj yeem pov tseg.Hmoov sau nyob rau hauv ib qho kev rov qab system yuav nyob twj ywm haum rau lwm qhov kev ua tau zoo tshaj plaws. Nws dhau los ua cov khoom ploj mus tas li thaum nws muab pov tseg, kis kab mob los yog siv tsis tau.
Khaws cov kev ntsuas no sib txawv:
| Ntsuas | Qhov nws piav | Yuav ua li cas kom tsis txhob xav tias |
|---|---|---|
| First-pass hloov efficiency | Qhov sib faib ntawm cov hmoov tawm hauv rab phom uas tso rau ntawm lub hom phiaj thaum lub sijhawm dhau mus | Nws tsis yog qhov kawg tau txais txiaj ntsig tom qab rov qab thiab rov siv dua. |
| Rov qab efficiency | Qhov sib faib ntawm overspray sau los ntawm cov khoom siv rov qab los | Kev sau tsis ua pov thawj tias cov hmoov tau dhau los ua cov txheej txheem. |
| Kev siv zaj duab xis zoo | Qhov sib faib ntawm cov hmoov net noj uas dhau los ua txheej ntawm qhov lees txais | Nws yog tshwj xeeb rau cov khoom, kev ua haujlwm thiab kev tshaj tawm ciam teb. |
| Muab pov tseg-hmoov tus nqi | Qhov sib faib ntawm net noj muab pov tseg raws li siv tsis tau xoob hmoov | Nws tsis suav nrog txhua lwm hom kev noj tsis zoo. |
Piv txwv li, ib tug reconciled batch noj100 kgtej zaum qhov chaw88 kgntawm qhov lees txais thiab4 kgntawm qhov tsis lees paub lossis cov khoom siv kho mob, thaum muab pov tseg8 kgntawm cov hmoov qhuav. Kev siv yeeb yaj kiab zoo yog thaum ntawd88%, pov tseg-hmoov tus nqi yog8%, thiab tag nrho cov tsis zoo noj yog12%. Qhov no yog ib qho piv txwv ntawm qhov sib npaug loj.
Siv net hmoov noj ua tus denominator thoob plaws qhov piv txwv ntawd. Cov hmoov rov qab uas tseem tshuav hauv cov khoom siv tau thaum kawg ntawm lub sijhawm tsis suav nrog kev noj.
Qhov twg cov hmoov poob mus tas li tshwm sim
Kev hloov xim tu, hose purging, lim residues, tshuaj ntsuam xyuas, paug thiab hmoov uas tsis tuaj yeem rov qab siv tau tag nrho tuaj yeem ua rau pov tseg. Kev khiav luv luv tuaj yeem nqa kev tu ntau dua rau ib square meter txais vim tias txhua qhov kev ntxuav tu ua haujlwm tsawg dua.
Reclaimed hmoov yuav tsum nyob twj ywm haum rau cov xaiv tiav. Paub meej txog cov kev tso cai rov qab rau cov qib pes tsawg, tshwj xeeb tshaj yog thaum cov tsos mob rhiab heev rau kev hloov pauv hauv cov khoom sib xyaw. Tsis txhob muaj qhov feem pua rov qab thoob ntiaj teb thoob plaws cov khoom sib txawv.
Yuav txo cov pov tseg yam tsis muaj kev txi zoo
Pab pawg ua haujlwm tau zoo nyob qhov twg ua tau zoo, ruaj khov rack loading, tswj cov khoom xa tuaj thiab khaws cov hmoov rov siv tau cais tawm ntawm cov khoom tsis huv. Kos kho-zaj duab xis thickness kom paub tias tsis tsim nyog overbuild.
Cov ntaub ntawv tsis lees paub ua haujlwm cais los ntawm cov hmoov xoob pov tseg. Pretreatment tsis zoo, kho tsis tiav lossis zoo li qhov tsis xws luag yuav tsum muaj kev kho sib txawv los ntawm kev sau cov tshuaj overspray los yog tu kom poob.
