1.YHow Qhov chaw nyob ntawm cov txheej txheem ntawm cov txheej txheem ntawm nws tus kheej cuam tshuam rau cov xim roughness ntawm cov xim coated kauj?
Substrate hom thiab roughness
Kub-Rolled Substrate: Qhov saum npoo yog ntxhib (RA feem ntau yog 3-5μm), thiab nws yooj yim kom muaj residual oxide nplai lossis cov khoom tsis xws luag (xws li cov menyuam cim cov menyuam). Nws yuav tsum tau ua kom txias-dov lossis ua tiav, txwv tsis pub txheej txheej yog yooj yim los qhia "ntxig ntxoov ntxoo".
Cold-rolled substrate: The surface is relatively smooth (Ra 0.8-1.5μm), but if the roller wears unevenly during the rolling process, it will cause the substrate to have "striped" roughness differences (such as the Ra deviation between the edge and the middle> 0.5μm).
Galvanized substrate: qhov loj ntawm zinc paj ncaj qha cuam tshuam kev ntxhib los mos, thiab lub qab zib me me
Substrate nto tsis xws luag
Pits, protrusions, khawb lossis roj seem ntawm cov pits tsis sib xws (cov txheej txheem tuab thiab yooj yim thiab yooj yim rau cov ntsiab lus)
2.Yog cov txheej txheem tshwm sim no puas cuam tshuam rau qhov chaw ntawm cov xim coated?
Degreasing thiab xeb Tshem Tawm
Yog tias cov roj hauv zos thiab oxide nplai ntawm cov txheej txheem tsis huv
Kev sib xyaw ntawm cov tshuaj hloov pauv kev hloov pauv zaj duab xis
Tsis ncaj ntawm phosphating zaj duab xis yuav ua rau muaj kev sib txawv ntawm qhov tsis sib xws; Yog tias cov zaj duab xis txheej dhau lawm lossis ploj, lub substrate yuav yog ib feem, thiab cov txheej yuav yooj yim tsim "ntawm no, ob leeg yuav ua rau muaj kev hloov pauv.
3.Yog cov txheej txheej ua rau txheej txheem cuam tshuam rau qhov chaw ntawm cov xim coated?
Cov lus ntawm cov txheej txheej Coller system
Deg nplaim thaiv ntawm txheej cov menyuam: tus RA tus nqi ntawm cov hlau cov menyuam xav tau kom phim cov phiaj txheej. Yog tias qhov ntxhib ntawm txheej doller doller nws tus kheej yog qhov tsis ncaj, nws yuav ncaj qha theej mus rau txheej txheej txheej.
Txheej Rau Cov Menyuam Siab Thiab Partalelism:
Ntau dhau los: cov txheej txheej tshaj-txuas ntxiv, cov txheej hauv zos ua nyias, thiab cov tsawg zuj zus;
Kev sib txawv dhau los yog kev sib cav sib txawv: cov txheej hloov txheej hloov chaw yog qhov tsis xwm yeem, thiab cov hauv zos tsub zuj zus, thiab hauv zos tsub zuj zus "ua pob", thiab cov roughness nce.
Kev ceev sib piv ntawm cov hlua khi mus rau substrate: thaum cov txheej txheem nrawm deviates los ntawm lub teeb tus nqi, cov cim kev sib tw "lossis" tsim kev sib txuam ", sib sau ua ntu zus".
Txheej kev ua tau zoo
Viscosity: Cov txheej txheem viscosity muaj fluidity tsis zoo thiab yog ib qho yooj yim los khaws cov qauv ntawm cov txheej txheej ntawm cov txheej txheem txheej, ua rau muaj kev kub siab; Cov txheej txheem pleev xim qis-viscosity muaj cov leveling zoo thiab smoother cov khaub ncaws, tab sis ntau dhau kev yuav muaj qhov tsis muaj zog los npog cov kev tsis meej. Yog hais tias lub substrate muaj cov pob me me, cov xim coating yuav tseem cuam tshuam.
Pigments thiab fitters: tsis sib xws xim particle loj lossis dispersion yuav ua rau "grainy xav" ntawm txheej txheej; Kev ntxiv ntau dhau ntawm cov tub rog yuav nce cov roughness ntawm txheej.
Kev nrawm nrawm: Yog tias cov xim dries sai sai, nws yuav ua rau cov dej tsis sib thooj ntawm cov nplaim dej, sib sau "thiab nce tus nqi ra.
4.Qhov kev kho tus txheej txheem cuam tshuam rau cov npoo av ntawm cov xim coated kauj?
Qhov Cub Kub Kub
Uneven kub yuav ua rau qhov sib txawv ntawm cov qib siab: cheeb tsam kub tau nce qib, thiab cov kev tsim cov "yin thiab Yang thiab Yang thiab Yang thiab Yang thiab Yang thiab Yang thiab Yang thiab Yang thiab Yang thiab Yang.
Kev kub dhau: cov txheej kub dhau-hla, thiab "Pinholes" tau tsim yooj yim rau saum npoo; Tsawg dhau qhov kub: tsis muaj zog kho, tsis txaus txheej hardness, thiab kev ua tiav thiab kev ua tiav yog xav tau "khawb" uas tsis sib thooj.
Txuam nrog kho lub sijhawm nrog kab ceev
Kab ceev nrawm heev: cov txheej yog kho ua ntej nws yog ua tiav qib, khaws cov pob me me thaum txheej;
Txoj kab ceev dhau heev: cov txheej txheej qeeb heev, uas yuav ua rau cov txheej sib ntxiv, ua kom muaj qhov tsis xws luag, thiab nce cov roughness.
Cua txias txoj kev
Tsis xwm yeem huab cua txias yuav ua rau txawv hauv zos shrinkage tus nqi ntawm cov txheej, tsim "micrapracks" lossis "tus nqi ra yuav nce ntxiv; Yog tias cov menyuam yaus cov menyuam yaus ntawm cov cua txias yog qhov tsis ncaj, "yuav nias rau ntawm cov txheej txheej, ncaj qha hloov cov ntxhib.
5.Txhua khoom thiab ib puag ncig ib puag ncig cuam tshuam rau saum npoo av ntawm cov xim xim-txheej coils?
Cov Khoom Siv Khoom Raug Zoo
Yog tias cov lus qhia cov menyuam thiab cov menyuam lub cev nruj ntawm cov chav tsev yog sib piv, cov txheej txheem tuab ntawm ntug yuav tsis sib xws, thiab yuav txawv ntawm qhov nruab nrab.
Hnav cov txheej txheej chais yuav ua rau cov menyuam nyob saum npoo kom dhia thiab ua ntu zus "yuav tshwm sim ntawm cov txheej txheej.
Ib puag ncig huv si
Yog tias muaj plua plav ntau heev nyob rau hauv cov txheej txheej sib dhos, plua plav ntog ntawm cov plaub hau ntub dej yuav tsim "pob zeb uas tsis muaj txiaj ntsig yuav nce siab; Kev ntub dej siab dhau yuav ua rau cov dej sib dhos kom zoo rau "re-moisten", cov cuab yeej cia yuav raug txo qis, thiab kev sib txhuam yuav hloov dua.
