1.Dab tsi yog cov txheej txheem ntau lawm rau xim -coated steel coils?
Loading thiab Uncoiling: Cold-rolled coils (los yog ntau tshaj, corrosion-resistant galvanized txias-rolled coils) yog loaded rau hauv cov kab ntau lawm.
Ua ntej-kev kho mob (Tshuaj ntxuav thiab Passivation):
Degreasing: Tshem cov roj thiab plua plav tawm ntawm qhov chaw txias -rolled coils.
Ntxuav dej.
Kev kho tshuaj hloov pauv tshuaj (piv txwv li, phosphating lossis chromating): Ua kom muaj qhov ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom phosphating los yog chromating phosphating los yog chromating phosphating los yog chromating Cov yeeb yaj kiab no ua raws li "choj," zoo heev txhim kho qhov adhesion ntawm substrate thiab cov txheej tom ntej thiab txhim kho corrosion kuj. Qhov no yog thawj tus yuam sij rau kev vam meej "lamination."
Primary Txheej / Uncoating:
Tom qab ziab hauv qhov cub, lub substrate yog thawj coated nrog primer. Lub primer lub luag haujlwm tseem ceeb yog tiv thaiv xeb, tiv thaiv corrosion, thiab zoo adhesion rau substrate thiab topcoat.
Tom qab txheej txheej, lub substrate yog ci thiab kho hauv qhov cub.
Topcoat / Finish Txheej:
Lub topcoat yog siv rau ntawm kho primer. Lub topcoat txiav txim siab qhov kawg tshwm sim thiab kev ua tau zoo ntawm cov khoom, nrog rau cov xim, gloss, huab cua tsis kam, thiab tshuaj tiv thaiv.
Cov khoom yog tom qab ntawd ci rau hauv qhov cub rau kev kho ntxiv.
Tom qab-kev kho mob (yeem):
Protective Film: Tiv thaiv qhov chaw los ntawm khawb thaum thauj thiab ua.
Embossing: Textured rollers yog siv rau emboss qauv xws li ntoo grain thiab pob zeb lis ua ntej los yog tom qab txheej tau kho.
Winding thiab Ntim: Cov xim kawg -coated coil khoom yog tom qab ntawd tsim.
2.Dab tsi yog cov txheej txheem thiab cov yam ntxwv ntawm cov nplaum nplaum?
Txheej txheem: Lub siab-kev ua tau zoo ntawm cov nplaum nplaum (xws li epoxy lossis polyurethane nplaum) yog sib npaug rau sab hauv (los yog cov khoom tseem ceeb) ntawm cov xim -coated ntawv. Tom qab ntawd, nws yog laminated nrog cov ntawv txias -rolled ntawv (los yog aluminium ntawv, hluav taws kub- resistant board, thiab lwm yam.) ua tus thaub qab phaj siv lub laminator nyob rau hauv tshwj xeeb siab thiab kub.
Nta: Haum rau cov vaj huam sib luag tiaj tus lossis tsuas yog nkhaus. Qhov tseem ceeb yog kev xaiv cov nplaum, uas yuav tsum xav txog kev sib khi lub zog, durability, thiab kub tsis kam.
3.Dab tsi yog cov txheej txheem thiab cov yam ntxwv ntawm kub - nias txoj kev sib xyaw?
Txheej Txheem: Yog tias cov khoom siv tseem ceeb yog cov khoom siv thermoplastic (xws li PVC lossis PE ua npuas ncauj), cov xim -coated daim ntawv, cov khoom tseem ceeb, thiab cov ntawv thaub qab tuaj yeem muab tso rau hauv cov xovxwm kub. Cua sov melts los yog softens saum npoo ntawm cov khoom tseem ceeb, khi nws mus rau sab sauv thiab qis hlau los xij nyob rau hauv siab.
Nta: High bonding zog; Feem ntau siv hauv kev tsim cov sandwich vaj huam sib luag nrog cov hlau ntsia hlau (xws li xim -coated steel pob zeb wool panels thiab polyurethane- kaw sandwich panels).
4.Dab tsi yog cov txheej txheem thiab cov yam ntxwv ntawm cov nplaim hluav taws sib xyaw?
Nws yog tsuas yog siv rau ntawm -site foamed polyurethane (PU) sandwich panels. Cov xim -coated daim ntawv ua haujlwm raws li cov txheej txheem sab saud thiab qis, nrog cov khoom sib xyaw foamed polyurethane raw khoom txhaj rau hauv nruab nrab. Thaum lub sijhawm ua npuas dej thiab nthuav dav, nws ruaj khov rau cov ntawv hlau thiab kho.
5.Dab tsi yog cov txheej txheem thiab cov yam ntxwv ntawm kev kho tshuab tom txoj kev?
Txheej Txheem: Cov txheej txheem yob tshwj xeeb yog siv los cuam tshuam cov xim -coated daim ntawv thiab lub vaj huam sib luag rov qab ntawm cov npoo los yog qhov chaw tshwj xeeb, qee zaum ntxiv nrog cov qauv nplaum rau kev sib khi. Feem ntau siv nyob rau hauv ib co composite duct panels los yog hniav panels.
Nta: Tsis muaj kua nplaum lossis cua sov yuav tsum tau; lub zog sib txuas yog mechanical.
