* 4: Cov ntaub ntawv saum toj no yog kuaj los ntawm peb tus kheej cov cuab yeej thiab cov cuab yeej.

Txheej txheem thov

Ceev faj Hauv Kev Thov

(1) Daim Ntawv Thov: Siv cov yeeb yaj kiab no tsuas yog tiv thaiv cov khoom siv hluav taws xob sib txuas thiab lwm cov qauv tsim.
(2) Pretreatment: Organic residues, stains vim tsis txaus dewatering thiab ziab ntawm tooj liab nto, tej zaum yuav ua rau polymerization ntawm resisting thiab nkag mus rau ntawm plating los yog etching tov.Thov qhuav kiag li tom qab dej yaug. Tshwj xeeb tshaj yog, thaum cov dej noo nyob hauv lub qhov, nws ua rau lub tsev pheeb suab tawg.
(3) Substrate preheating: Preheating ntawm qhov kub thiab txias rau lub sijhawm ntev yuav ua rau xeb.Nws yuav tsum tau ua kom tsawg dua 10 min ntawm 80 ℃ thiab tsawg dua 3 min ntawm 150 ℃. Thiab thaum lub substrate saum npoo kub ua ntej lamination tshaj 70 ℃, zaj duab xis thickness ntawm ib tug los ntawm lub qhov ntug yuav dhau los ua nyias thiab tej zaum yuav ua rau tenting breakage.
(4) Tuav tom qab lamination thiab raug: Tuav nrog lub teeb thaiv lub teeb lossis hauv qab lub teeb daj (2 meters lossis ntau dua qhov yuav tsum tau muaj). Qhov siab tshaj plaws tuav lub sij hawm nyob rau hauv rooj plaub tom kawg (hauv qab lub teeb daj) yog 4 hnub. Kev nthuav tawm yuav tsum tau ua tsis pub dhau 4 hnub tom qab lamination.Kev tsim kho yuav tsum tau ua tsis pub dhau 3 hnub tom qab raug. Ray ntawm lub teeb tsis-ultraviolet dawb muaj qee cov kab hluav taws xob ultraviolet, yog li tuav nrog lub teeb thaiv los ntawm cov ntawv dub hauv qab nws.Kub kub 23 ± 2 ℃ thiab cov av noo ntawm 60 ± 10% RH. Laminated substrates yuav tsum muab tso rau hauv ib lub khib nyiab ib los ntawm ib qho.
(5) Kev Txhim Kho: Thaum qhov kub ntawm tus tsim tawm tshaj 35 ℃, nws tuaj yeem ua rau cov profile tsis zoo.
(6) Stripping: Tshem tawm hauv ib lub lis piam tom qab lamination.
(7) Kev kho khib nyiab: Cov khoom siv zaj duab xis qhuav hauv tus tsim tawm thiab stripper tuaj yeem coagulated los ntawm neutralization. Cov coagulated Cheebtsam tuaj yeem raug cais tawm ntawm cov tshuaj aqueous los ntawm kev lim xovxwm thiab txoj kev centrifugal. Cov kua dej sib cais muaj qee qhov COD thiab BOD, yog li nws yuav tsum tau muab pov tseg pov tseg kom raug.
(8) Xim xim: Cov xim yog ntsuab / xiav. Txawm hais tias cov xim yuav maj mam discolor nrog lub sij hawm, nws yuav tsum tsis txhob cuam tshuam tus yam ntxwv.

Ceeb Toom Txog Cia

(1) Thaum khaws cia rau hauv qhov tsaus, txias, thiab qhuav qhov chaw ntawm qhov kub ntawm 5 ~ 20 ℃ thiab cov av noo ntawm 60% RH lossis qis dua, cov zaj duab xis qhuav yuav tsum siv li ntawm 50 hnub tom qab tsim khoom.
(2) Khaws zaj duab xis yob kab rov tav los ntawm kev siv cov racks lossis cov rooj txhawb nqa rau kev khaws cia. Thaum lawv muab tso rau hauv vertically, cov nplooj ntawv ntawm cov yeeb yaj kiab qhuav tuaj yeem plam ib qho los ntawm ib qho thiab yob-puab yuav zoo li xyoob sprout (cov yob tau muab tso rau hauv kab rov tav hauv ib pob).
(3) Tshem tawm cov yeeb yaj kiab los ntawm cov ntawv dub hauv qab lub teeb daj lossis tib yam teeb pom kev zoo. Tsis txhob cia lawv nyob rau hauv lub teeb daj rau lub sijhawm ntev. Npog zaj duab xis yob los ntawm daim ntawv dub thaum koj khaws lawv rau ntev.
