1.What yog cov kev sim ua kom puas muaj rau txhua hom xim coated coils?
Kev ntsuam xyuas tus ntoo khaub lig txiav yog txiav cov txheej rau cov txheej txheem substrate thiab soj ntsuam cov txheej txheem ntawm cov txheej txheem los txiav txim siab txog qib adhesion. Cov kauj ruam thiab ntsuas cov txheej txheem yog raws li hauv qab no:
Cov Cuab Yeej Ntsuas
Single-blade or multi-blade scribing tool (blade spacing is 1mm, 2mm, and 3mm, selected according to coating thickness: 1mm for coating thickness ≤60μm, 2mm for 60μm-120μm, and 3mm for >120μm);
Mos txhuam (kom tshem tawm cov khib nyiab txiav);
3M 600 lossis cov xev sib npaug (ruaj khov nplaum (dav 25mm).
Kuaj cov kauj ruam
Kos ib 10 hli × 10mm square daim phiaj rau saum npoo ntawm cov xim-txheej coil. Cov kab sib chaws yuav tsum yog txawm tias ntsug, thiab qhov tob yuav tsum txig cov txheej kom ncav cuag lub substrate;
Siv txhuam txhuam kom txhuam cov kab sib chaws 5 zaug kom tshem tawm cov khib nyiab;
Lo kab xev ncaj rau ntawm daim phiaj, nias nrog koj cov ntiv tes kom ntseeg tau tias tsis muaj npuas, thiab tom qab ntawd mam li muag tawm ntawm lub kaum sab xis ntawm 60℃mus rau saum npoo;
Saib xyuas cov kev tso quav ntawm cov txheej hauv kab sib chaws.
Qib ntsuas qib (0-5, qib siab dua, qhov tsis zoo ntawm adhesion)
Theem 0: Lub ntug txiav yog du tag, tsis muaj txheej txheej shedding;
Qib 1: Ib qho me me ntawm cov txheej txheem shedding tshwm sim ntawm kev sib tshuam ntawm kev sib tshuam, nrog rau thaj chaw ntawm cov chaw ntawm tsawg dua lossis sib npaug rau 5%;
Theem 2: Txheej txheej tshwm sim ntawm txoj kev txiav lossis kev sib tshuam, nrog thaj chaw ntawm 5% -15%;
Theem 3: Ib feem ntawm cov txheej txheej txheej tshwm sim ntawm ntug kev txiav, lossis coating poob hauv daim phiaj, nrog thaj chaw ntawm 15% -35%;
Theem 4: Qhov ntau ntawm cov txheej txheem ua rau muaj tshwm sim ntawm ntug kev txiav, lossis coating poob rau hauv daim phiaj, nrog thaj chaw ntawm 35% -65%;
Qeb 5: Cov Khoom Siv Ntawm Cov Khoom Siv> 65%, lossis Txheej Txheej Txheem Ua Haujlwm tshwm sim dhau thaj chaw loj.
2.Yog cov hau kev uas tsim nyog yog tsim nyog rau nyias los yog yoog raws?
Lub puab ntsuas siv rab riam ncig mus rau kos lub voj voog ntawm txheej txheej txheej thiab ntsuas cov txheej txheej ntawm sab hauv ntawm lub voj voog. Nws yog tsuas yog siv nyob rau hauv cov xwm txheej uas yuav tsum tau yooj yim dua (xws li cov xim xim-coated coils rau kev ua thiab moulding).
Cov Cuab Yeej Ntsuas
Lub voj voog adhesion tes tester;
Mag cia iav.
Kuaj cov kauj ruam
Kho cov qauv, tso cov ntaub pua chaw tso rau saum npoo av, siv lub voj voog uas tau sau tseg, thiab kos lub voj voog nrog txoj kab uas hla ntawm 7.5mm ntawm kev nrawm ntawm 20 hli / s. Lub puab yuav tsum txig cov txheej txheem rau lub substrate;
Soj ntsuam cov tev ntawm cov txheej hauv lub voj voog.
Qib ntsuas qib (1-7, qis dua qib, qhov zoo dua adhesion)
Qib 1: Tsis muaj txheej tev, cov khawb yog tus;
Theem 2: Ib qho me me ntawm tev tshwm sim ntawm ntug ntawm qhov khawb, tsis tshaj 5% ntawm thaj chaw voj voog;
Qeb 3: Thaj Chaw Thaj Av 5% -15%;
Qib 4: chaw muag khoom thaj tsam 15% -35%;
Qeb 5: chaw muag tshuaj 35% -65%;
Qeb 6: Chaw muag khoom 65% -85%;
Theem 7: chaw rau ntawm Cheeb Tsam> 85%.
3.Qhov twg yog lwm cov kev ntsuas ib pab pawg?
Adhesion tom qab kev ua: rau cov coils coil uas yuav tsum tau khoov lossis ntaus cim hla (xws li 180℃khoov). Cov txheej yuav tsum tsis txhob poob rau ntawm kev txhais tau, txwv tsis pub nws suav hais tias qhov nplaum tom qab kev ua haujlwm tsis tsim nyog; Cov khoom nplaum tom qab ntub dej kub / cov ntsev ua haujlwm: qee qhov kev coj ua uas ntub dej los ntsuas qhov kev sib tw ntawm cov txheej txheem hluav taws xob, thiab tom qab ntawd cov tshuaj ntsuam Feem ntau, cov qib yuav tsum tau hloov pauv.
4.How qhov zoo ntawm cov kev kho mob ntawm thaj chaw seem cuam tshuam rau cov nplaum ntawm cov xim coated coils?
Nto huv: Yog tias muaj roj, xeb lossis hmoov av nyob rau ntawm lub substrate, uas yuav cuam tshuam rau kev sib cais ntawm cov tshuaj ntawm txheej thiab lub substrate.
Cov roughness saum npoo: tsim nyog roughness tuaj yeem nce thaj tsam ntawm nruab nrab ntawm cov txheej txheem thiab cov nyhuv (" Hloov siab, ntau dhau ntawm cov khawb av thiab pitting) yuav ua rau tsis sib xws ntawm txheej ntawm txheej, thiab txawm tias pinholes yuav cuam tshuam, uas yuav cuam tshuam cov adhesion.
Kev hloov kho kev hloov pauv hloov pauv: Pretreatment ntawm substrate nto (xws li phosphating, passivation kev kho mob los txhim kho kev sib txuas lus ntawm txheej ntawm txheej thiab substrate. Piv txwv li, tom qab chromate passivation, cov nplaum ntawm cov primer tuaj yeem txhim kho kom zoo dua ntawm cov ntawv galvanized; Yog tias cov yeeb yaj kiab hloov dua siab dhau los yog tu, nws yuav ua rau muaj kev txo qis hauv cov nplaum hauv zos.
5.Yog ua cov txheej txheem txheej txheem tsis cuam tshuam cov txheej nplaum?
Cov tuab tuab: Thaum txheej txheej yog qhov nyuaj heev, nws yog qhov nyuaj rau tsim cov duab ua ntej thiab tsis zoo rau hauv zos yuav ua rau tsis txaus; Thaum nws tuab heev, kev ntxhov siab sab hauv thaum lub sij hawm kho yuav loj heev (resin shrinkage), ua rau tev thiab lub substrate, tshwj xeeb yog thaum tab tom ua. Piv txwv li, qhov tuab ntawm tus thawj primer yog tswj tau ntawm 5-10μm, thiab lub topcoat yog 15-25μm. Yog tias tag nrho cov tuab tuab heev heev (xws li ntau tshaj 60μm), ib qho kev ua haujlwm zoo dua yuav tsum sib phim.
Kev kho qhov kub thiab sijhawm thiab sijhawm: cov txheej yuav tsum tau mus txog qhov ntsuas kub (xws li kev kho tus kab ke ntawm polyester) thiab sijhawm los ua kom muaj kev sib txuas yog los ua ib zaj duab xis. Yog tias kev kho tus kheej tsis txaus (qhov ntsuas kub tsawg dhau los yog luv heev), lub resin yuav tsis ua kom tiav, cov cuab yeej siv cov khoom siv tsis zoo, thiab cov nplaum yuav txo qis; Yog tias nws yog overcured (qhov ntsuas kub dhau lawm), lub resin yuav ua rau, ua rau cov txheej sib tsoo, uas tseem cuam tshuam rau cov nplaum.
Cov khoom siv txheej txheej kom raug: Uneven cov menyuam sab saum toj siab thiab mismatch ntawm txheej tshuab thickness lossis cov txheej hauv zos rolissions; Tsis zoo Atomization ntawm cov phom txau yuav ua rau cov khoom faib tsis sib xws ntawm cov hmoov txheej txheem (xws li cov hmoov xim xim (tsim "txiv kab ntxwv tev" lossis pinholes, thiab txo cov nplaum kom ruaj khov.
