1.Dab tsi yog qhov laj thawj tseem ceeb rau "txiv kab ntxwv tev kev ntxhib los mos" ntawm qhov chaw ua ntej-coated steel coils?
Tsis txaus Coating Leveling
Cov txheej txheej viscosity ntau dhau los yog qhov tsis tsim nyog ua rau cov dej tsis zoo.
Cov resin tsis zoo- cov kuab tshuaj sib txuam hauv cov txheej txheem txheej ua rau evaporation sai heev.
Txheej txheej txheej txheem teeb meem
Cov Txheej Txheem Txheej Txheem Tsis Zoo: Kev sib tw ntawm cov menyuam tsis sib haum thiab cov kev sib tshuam - cov menyuam cov siab ua rau cov txheej txheem tsis sib xws lossis tsis txaus hloov.
Kev Tiv Thaiv Zaj Duab Tsis Txaus Ntsig: Ntau cov yeeb yaj kiab tuab lossis nyias ntub dej cuam tshuam rau qib.
Curing Temperature/Speed Mismatch: Kev kho sai heev thaum lub sij hawm ci ua rau cov kuab tshuaj evaporation los ntawm cov txheej hauv qab, ua rau tsis sib xws.
Substrate los yog primer txheej xwm txheej
Substrate kub uas siab dhau los yog qis dhau cuam tshuam rau txheej txheej ntub dej.
Loj roughness los yog me ntsis unevenness nyob rau hauv lub primer txheej amplifates defects nyob rau hauv lub topcoat.
2.Dab tsi yog kev daws teeb meem?
Kho Txheej Txheej Parameter:
Optimizing Thinner: Xaiv qhov qeeb - ziab kom qhuav kom ncua sij hawm theem.
Kho Viscosity: Tswj cov txheej txheej viscosity nyob rau hauv qhov tsim nyog raws li cov txheej txheem txheej txheem txheej txheem (feem ntau saib xyuas siv Ford khob lossis viscometer rotational).
Kev sib koom tes nrog cov neeg muab khoom siv: Txhim kho cov txheej txheem txheej txheej thiab ua kom muaj kev faib ua feem ntawm kev pab cuam theem (xws li siloxanes lossis acrylic leveling agents).
Tswj lub substrate thiab txheej txheej:
Xyuas kom lub substrate yog huv si thiab nyob rau hauv ib tug ruaj khov kub (nws yog pom zoo kom tswj lub substrate kub nrog dej txias nyob rau hauv lub caij ntuj sov).
Txheeb xyuas qhov roughness ntawm cov primer txheej (Ra tsawg dua lossis sib npaug ntawm 0.8μm yog qhov nyiam); polish los yog kho cov txheej txheem primer yog tias tsim nyog.
Environmental thiab Equipment Management
Tswj qhov kub thiab av noo ntawm chav txheej txheej (pom zoo kub 20-30 degree, av noo tsawg dua lossis sib npaug li 70%).
Tsis tu ncua tuav cov menyuam coater kom ntseeg tau tias cov menyuam nto huv si thiab tsis muaj kev puas tsuaj.
Tshawb xyuas cov cua nrawm ntawm qhov cub nozzles kom tsis txhob muaj cua ncaj qha mus rau ntawm txheej txheej.
3.Yuav ua li cas los txhim kho cov txheej txheem txheej txheem?
Roller Txheej Txheej Txheej Txheem Kho:
Txheeb xyuas qhov sib piv ceev ntawm cov txheej txheej cov menyuam thiab cov menyuam pub noj kom ntseeg tau tias cov xim hloov tsis sib xws.
Kho cov menyuam siab kom tsis txhob muaj compression ntau dhau uas tuaj yeem ua rau kev ntxhib los mos.
Curing Profile Optimization:
Tsim nyog txo qhov kub ntawm qhov cub thiab txuas ntxiv rau theem theem (flash zone) lub sijhawm.
Ua kom lub qhov cub zoo sib xws thiab tsis txhob muaj cua sov hauv cheeb tsam (qhov kub sib txawv yuav tsum tau tswj kom zoo li ± 5 degree).
4.Dab tsi yog cov kauj ruam rau kev ceev ceev ntawm - qhov chaw tshawb xyuas?
Saib xyuas qhov tsis tu ncua ntawm qhov tsis xws luag:
Yog hais tias cov txiv kab ntxwv tev kev ntxhib los mos tshwm sim, xyuas seb puas muaj kev puas tsuaj rau cov menyuam txheej los yog cov menyuam rov qab.
Yog tias qhov kev faib tawm tsis sib xws, tsom mus rau kev tshawb xyuas cov txheej txheem lossis ib puag ncig.
Me me-batch kuaj xyuas:
Kho ib qho kev sib txawv (xws li hom thinner, roller ceev piv) thiab sib piv cov teebmeem.
Siv lub rooj sib tw ntsuas qib los simulate cov xwm txheej tsim khoom.
Instrument-pab tsom xam:
Siv lub ntsuas ntsuas gloss los xyuas qhov sib xws ntawm gloss nto (txiv kab ntxwv tev kev ntxhib los mos feem ntau yog nrog los ntawm kev hloov pauv ntawm gloss tus nqi ntawm 60 degree).
Quantify nto roughness (Sa tus nqi) siv 3D profileometer.
5.Qhov kev tiv thaiv yog dab tsi?
Tsim cov txheej txheem qhov rais: Sau thiab ua kom muaj zog ntawm qhov tso cai rau cov tsis tseem ceeb (viscosity, roller ceev, kub, thiab lwm yam).
Tsis tu ncua saib cov txheej txheem kev ua tau zoo: Kev ntsuas qib thiab kho ceev rau txhua pawg txheej txheej.
Cov neeg tsav tsheb ciav hlau: Txhim kho lawv qhov kev nkag siab zoo rau cov txheej txheem txheej txheej thiab cov khoom siv tsis zoo.
