I-PCB inki ibhekisa ebhodini lokuphrinta (ibhodi yesifunda ephrintiwe, okubizwa nge-PCB) kukayinki, izici ezibalulekile zomzimba weyinki yi-viscosity, thixotropy, kanye ne-fineness. Lezi zakhiwo zomzimba zidinga ukwaziwa ukuthuthukisa ikhono lokusebenzisa uyinki.

1. Viscosity and thixotropy

Enqubeni ephrintiwe yokukhiqiza ibhodi lesifunda, ukuphrinta kwesikrini kungenye yezinqubo ezibaluleke kakhulu. Ukuze uthole ukwethembeka kokukhiqizwa kabusha kwesithombe, uyinki kufanele abe ne-viscosity enhle ne-thixotropy efanelekile. Okubizwa ngokuthi yi-viscosity ukungqubuzana kwangaphakathi ketshezi, okusho ukuthi ngaphansi kwesenzo samandla angaphandle, ungqimba olulodwa lwamaslayidi ketshezi kolunye ungqimba lwamanzi, namandla okubanga afakwa ungqimba lwangaphakathi lwamanzi. Uketshezi oluwugqinsi lwangaphakathi olujiyile luhlangabezane nokuphikiswa okukhulu kwemishini, ukumelana ketshezi okuncane kuncane. I-viscosity ilinganiselwa emachibini. Ngokuyinhloko, kufanele kuqashelwe ukuthi izinga lokushisa linomphumela ophawulekayo ku-viscosity.

I-Thixotropy iyimpahla ebonakalayo yoketshezi, okungukuthi, i-viscosity ye-liquid iyancipha ngaphansi kokuphazamiseka, futhi maduzane ibuyisela ku-viscosity yayo yangempela ngemuva kokuma. Ngokushukumisa, isenzo se-thixotropic sihlala isikhathi eside ngokwanele ukwakha kabusha ukwakheka kwangaphakathi. Ukufeza umphumela wokuphrinta wesikrini osezingeni eliphakeme, uyinki thixotropy ubaluleke kakhulu. Ikakhulukazi kunqubo yokuphrinta, uyinki uyanyakaziswa bese wenza uketshezi lwawo. Le ndima isheshisa uyinki ngejubane le-mesh, ikhuthaza umugqa wokuqala ohlukanisiwe uyinki ngokulinganayo oxhunywe koyedwa. Lapho iscraper iyeka ukuhamba, uyinki ubuyela esimweni esimile, futhi i-viscosity yayo ibuyela ngokushesha kudatha edingekayo yasekuqaleni.

I-2. I-Fineness

Izingulube nokugcwaliswa kwamaminerali ngokuvamile kuqinile, kugaywe kahle kube usayizi wezinhlayiyana ezingekho ngaphezu kuka-4/5 micron, bese kwakha ukugeleza okufana ngendlela eqinile. Therefore, it is very important to require fine ink.

Uhlobo lwe-PCB uyinki

I-PCB inki ihlukaniswe kakhulu ngemigqa emithathu, ivimbela ukushisela, inki yomlingiswa izinhlobo ezintathu.

Uyinki wolayini usetshenziswa njengongqimba lwesithiyo ukuvimbela ukubola komugqa lapho kudwetshwa ukuvikela umugqa, uhlobo oluzwelayo luketshezi ngokuvamile. There are two kinds of acid corrosion resistance and alkaline corrosion resistance, alkali resistance is more expensive, this layer of ink in the corrosion of the line uses alkali to dissolve it.

Uyinki weSolder upendwe kulayini njengomugqa wokuvikela ngemuva komugqa. Kukhona uketshezi lokwelashwa okunamandla nokushisa, kanye nezinhlobo zokuqina ze-ultraviolet, gcina iphedi ebhodini, izinto zokushisela ezikahle, ukwahlukanisa, nokumelana ne-oxidation.

Uyinki womlingiswa usetshenziselwa ukwenza ukumaka ngaphezulu kwebhodi, njengokumaka izimpawu zezinto, imhlophe imhlophe.

Eqinisweni, kukhona amanye ama-inki, afana no-inki wokuxebuka, ukwenza i-plating yethusi noma ukwelashwa ngaphezulu akudingeki ukuthi kubhekane nengxenye yokuvikelwa, bese kungasuswa; Uyinki wesiliva njalonjalo.

Izindaba zokusebenzisa inki ze-PCB ezidinga ukunakwa

Ngokwesipiliyoni sangempela sokusetshenziswa kukayinki ngabakhiqizi abaningi, ukusetshenziswa kukayinki kufanele kwenziwe ngokuya ngemibandela elandelayo:

1. Kunoma ikuphi, izinga lokushisa kukayinki kufanele ligcinwe ngaphansi kuka-20-25 ℃, ukushintsha kokushisa akukwazi ukuba kukhulu kakhulu, ngaphandle kwalokho, kuzothinta i-viscosity yekhwalithi yekhwalithi nokuphrinta kwesikrini nomphumela.

Ikakhulukazi lapho i-inki igcinwa ngaphandle noma igcinwe emazingeni okushisa ahlukene, kufanele ibekwe endaweni okushisa kuyo ukuzivumelanisa nezinsuku ezimbalwa noma yenze umgqomo wenki ukufezekisa izinga lokushisa elifanele. Lokhu kungenxa yokuthi ukusetshenziswa kukayinki obandayo kuzodala ukwehluleka kokuphrinta kwesikrini, kudale inkinga engenasidingo. Ngakho-ke, ukugcina ikhwalithi uyinki, kungcono ukugcina noma ukugcina ezimeni zenqubo yokushisa ejwayelekile.

2. Ngaphambi kokusetshenziswa, uyinki kufanele agcwaliswe ngokugcwele nangokucophelela ngesandla noma ngomshini ngokulinganayo. Uma uyinki emoyeni, sebenzisa ukuma isikhathi esithile. Uma kudingeka ukuxubeka, hlanganisa kahle kuqala bese uhlola i-viscosity. Umgqomo uyinki kufanele uvalwe ngokushesha ngemuva kokusetshenziswa. Ngasikhathi sinye, ungalokothi ubeke uyinki wesikrini emgqonyeni wenkino kanye noyinki ongasetshenziswanga oxutshwe ndawonye.

3. I-ejenti yokuhlanza ebikusebenzise kangcono ukujwayelana yenza inetha elicacile, futhi ifuna ukuhlanzeka ngokuphelele. Lapho uhlanza futhi, kungcono ukusebenzisa i-solvent ehlanzekile.

4. Ukomisa i-inki, kufanele kube nohlelo oluhle lokukhipha kudivayisi.

5. Ukugcina izimo zokusebenza kufanele zihlangabezane nezidingo zobuchwepheshe besiza sokusebenza sokuphrinta kwesikrini.

Iyini indima ye-PCB inki enqubeni yokukhiqiza ye-PCB

Uyinki udlala indima ekukhiqizweni kokuvikelwa kwe-foil yesikhumba ukuze isikhumba sethusi singadalulwa, sizothinta inqubo elandelayo, uyinki obucayi, uwoyela wekhabhoni, uwoyela wesiliva, kanye ne-carbon oyela kanye ne-oyela lesiliva kunokuqhutshwa kwempahla okufanele kwenziwe, okuvame ukusetshenziswa kombala weyinki , uwoyela omhlophe, uwoyela oluhlaza, uwoyela omnyama, uwoyela oluhlaza okwesibhakabhaka, uwoyela obomvu, ibhotela.
