PCB horumarinta khad alxanka

Si loo wanaajiyo waxtarka alxanka loogana fogaado waxyeelo soo gaarta qaybaha aan u baahnayn alxanka inta lagu jiro wax soo saarka PCB, qaybahan waxay u baahan yihiin in lagu ilaaliyo khad xannibaya. Horumarinta khad PCB waxay si dhow ula xiriirtaa tignoolajiyada qalabka, xaaladaha alxanka iyo shuruudaha khadka. PCB-ga cufnaanta sare ee dheeraadka ah iyo muuqaalka tignoolajiyada alxanka ee bilaa rasaasta ah, shuruudo cusub ayaa loo soo bandhigay si loo hagaajiyo viscosity khadka oo looga dhigo mid buuxiya shuruudaha khad khad jet ah oo daabacaadda Khadka PCB waxa uu leeyahay afar marxaladood oo horumar ah, laga bilaabo nooca filimka hore ee engegan iyo nooca kulaylka si tartiib tartiib ah u horumaray ilaa ULTRAVIOLET (UV) nooca hagaajinta iftiinka, ka dibna u muuqday sawir sawir leh oo soo saaraya khad alxanka.

1. Viscosity hoose wuxuu noqon karaa khad alxanka-jet ah

Horumarinta warshadaha elektiroonigga ah, farsamo elektiroonig ah oo daabacan oo dhammaystiran oo leh hab dheeri ah ayaa soo ifbaxaya waqtiga saxda ah. Habka isku darka wuxuu leeyahay faa’iidooyinka badbaadinta alaabta, ilaalinta deegaanka, habka la fududeeyay, iwm. Iyadoo ay ugu wacan tahay isticmaalka daabacaadda inkjet-ka ee farsamada ugu weyn, waxaa jira shuruudo cusub oo loogu talagalay sifooyinka khad iyo qalabka jirka, oo inta badan lagu muujiyay sida:

(1) xakamee viscosity khad, si loo hubiyo in si joogto ah loogu buufin karo sanka, si looga hortago in furku la kulmo

(2) xakamee xawaaraha falcelinta bogsashada, gaadho adkaynta bilowga ah ee degdegga ah, ka hortagga khad ku jira mareegaha sababta oo ah soo -gelinta iyo faafinta;

(3) Hagaaji thixotropy khad si aad u hubiso tayada iyo soo celinta khadka daabacaadda. Horumarinta khad alxanka viscosity hooseeya, isticmaalka ugu weyn ee wax ka beddelka alaabta alxanka, oo lagu kabo shuruudaha shahaadada firfircoon ama firfircoon.

2. FPC khad alxanka

Iyadoo horumarinta warshadaha PCB, baahida FPC si degdeg ah u koraan, iyo shuruudo cusub ayaa la soo bandhigay qalab u dhigma. Sababtoo ah siliga naxaasta ah ee saxan flexo waa ay fududahay in la oxidize, walxaha iska caabbinta alxanka ee siliga flexo waxay noqdeen goob cilmi baaris ah. Filimka caabbinta epoxy-ga ee dhaqameed wuxuu muujinayaa jalaqsi sare ka dib daawaynta oo kuma habboona flexography. Sidaa darteed, furaha lagu xallinayo dhibaatada waa in la soo bandhigo qaybta silsiladda dabacsan qaab dhismeedka resin-dhaqameedka iyo in la ilaaliyo waxqabadka alxanka caabbinta asalka ah. Khadku wuxuu leeyahay xasillooni kaydineed oo wanaagsan, wuxuu si fiican u milmi karaa xalka sodium carbonate, xal ammonia, daaweynta makaanikada filimka, kulaylka, aashitada iyo guryaha alkali waxay buuxiyaan shuruudaha ku habboon.

3. Khad alxanka sawireed oo biyo-milmi kara

Si loo yareeyo qiiqa dareerayaasha organic ee habka wax soo saarka PCB iyo in la yareeyo saamaynta dareere on deegaanka, alxan xannibaya khad ayaa si tartiib tartiib ah u horumaray ka habka horumarinta dareere organic si milo horumarinta biyaha alkaline, iyo sannadihii la soo dhaafay, waxa uu horumariyo si ay biyaha. farsamada horumarinta. Isla mar ahaantaana, si loo buuxiyo shuruudaha tignoolajiyada alxanka-free-lead ee filimka iska caabinta, hagaajinta caabbinta waxqabadka heerkulka sare.

4. LED leh khad cad oo milicsi sare leh

TaiyoInk waxay markii ugu horreysay soo bandhigtay khad xannibaado cad oo loogu talagalay baakadaha LED 2007. Marka la barbar dhigo khad dhaqameedka, khad alxanka cad wuxuu u baahan yahay inuu xalliyo dhibaatooyinka midab-la’aanta iyo da’da dedejinta ee ay keento soo-gaadhista muddada-dheer ee isha iftiinka. Khad alxanka epoxy-dhaqameedka sababtoo ah qaab-dhismeedka molecular ka kooban yahay giraanta benzene, iftiinka muddada-dheer waa sahlan tahay inuu keeno midab. Ilaha iftiinka LED-ka, dahaarka caabbinta alxanka ayaa ku dahaaran ka hooseeya walxaha luminescent, sidaas darteed waxaa lagama maarmaan ah in la hagaajiyo waxtarka milicsiga ee daahan caabbinta alxanka iftiinka, ka dibna kor loo qaado iftiinka isha iftiinka. Tani waxay soo bandhigaysaa caqabad cusub cilmi baarista walxaha alxanka iska caabinta.

Gunaanad

Cilmi-baarista khad alxanka had iyo jeer waa meel adag warshadaha PCB. Iyada oo wareegga daabacaadda ka habka kala-goynta si tartiib tartiib ah in habka dheeraadka ah, daabacaadda inkjet sida habka ugu weyn ee farsamada ee habka dheeraadka ah, viscosity ee khad alxanka, thixotropy iyo falcelinta soo bandhigay shuruudaha sare; Caannimada tignoolajiyada alxanka ee bilaa rasaasta ah ayaa soo bandhigtay shuruudo cusub oo loogu talagalay iska caabbinta heerkulka sare ee filimka alxanka, horumarinta qulqulka alxanka cusub wuxuu si degdeg ah ugu baahan yahay tiro badan oo cilmi-baarayaal ah, iyo cilmi baarista khad alxanka ayaa kor u kacaya, kaas oo leh weyn kartida.
