Inki ya PCB imatanthawuza bolodi yosindikiza (bolodi losindikizidwa, wotchedwa PCB) wa inki, mawonekedwe ofunikira a inki ndi mamasukidwe akayendedwe, thixotropy, ndi fineness. Zinthu zakuthupi izi zimayenera kudziwika kuti zithetse kugwiritsa ntchito inki.

Makhalidwe a inki ya PCB

1. Kukhuthala ndi thixotropy

Mu makina osindikizira oyang’anira dera, kusindikiza pazenera ndi imodzi mwanjira zofunika kwambiri. Kuti tipeze kukhulupirika kwa kubereka kwazithunzi, inki iyenera kukhala ndi mamasukidwe akayendedwe abwino komanso thixotropy yoyenera. Zomwe zimatchedwa kukhuthala ndi mkangano wamkati wamadzi, zomwe zikutanthauza kuti mothandizidwa ndi mphamvu yakunja, gawo limodzi lamadzimadzi limatsetsereka pamadzi ena, komanso mphamvu yotsutsana yomwe imakhala ndi mkatikati mwa madzi. Wosanjikiza wamkati wosanjikiza wotsekemera amakumana ndi kukana kwamakina kwambiri, kuwonda kwamadzi kochepa. Kukhuthala kumayesedwa m’madziwe. Makamaka, tiyenera kukumbukira kuti kutentha kumakhudza kwambiri kukhuthala.

Thixotropy ndi katundu wamadzi, ndiye kuti mamasukidwe akayendedwe amadzimadzi amachepa, ndipo posachedwa abwezeretsa kukhuthala koyambirira atayimirira. Pogwedeza, zochita za thixotropic zimatha nthawi yayitali kuti zikhazikitsenso kapangidwe kake kamkati. Kuti tikwaniritse mawonekedwe abwino kwambiri, inki thixotropy ndiyofunika kwambiri. Makamaka popukutira, inki imagwedezeka ndikupanga madzi ake. Udindo uwu umathamangitsa inki kudzera pa liwiro la mauna, umalimbikitsa mzere wapachiyambi inki yosakanikirana yolumikizana. Chodulira chikangosuntha, inkiyo imabwerera kumalo osasunthika, ndipo kukhuthala kwake kumabwereranso kuzidziwitso zoyambirira.

2. Fineness

Zikopa ndi ma filler amadzaza nthawi zambiri amakhala olimba, osalala bwino kuti akhale tinthu zosaposa 4/5 micron, ndipo amapanga mawonekedwe ofanana mokhazikika. Chifukwa chake, ndikofunikira kwambiri kufuna inki yabwino.

Mtundu wa PCB inki

Inki ya PCB imagawika mizere itatu, kutsekereza, mtundu wa inki mitundu itatu.

Inki ya mzere imagwiritsidwa ntchito ngati chotchinga kuti muchepetse kutentha kwa mzere mukamakhazikika kuti muteteze mzerewo, mtundu wovuta wamadzi. Pali mitundu iwiri ya kukana dzimbiri asidi ndi kukana zamchere dzimbiri, kukana soda ndi okwera mtengo, izi wosanjikiza inki mu dzimbiri la mzere ntchito soda kupasuka.

Inki ya Solder yajambulidwa pamzere ngati chingwe chodzitchinjiriza pambuyo pa mzere. Pali madzi ozizira komanso otenthetsera, komanso mitundu yolimba ya ma ultraviolet, sungani padi pa bolodi, zida zowotcherera, zotsekemera, komanso kukana makutidwe ndi okosijeni.

Inki yamakalata imagwiritsidwa ntchito kupangira chikhomo, monga kuyika chizindikiro cha zigawo zikuluzikulu, makamaka zoyera.

M’malo mwake, pali inki zina, monga inki yosenda, ndikuchita zokutira zamkuwa kapena chithandizo cham’mwamba sichiyenera kuthana ndi gawo lina lachitetezo, kenako nkuchotsedwa; Inki ya siliva ndi zina zotero.

PCB inki ntchito zinthu zofuna chidwi

Malinga ndi momwe inki imagwiritsidwira ntchito ndi opanga ambiri, kugwiritsa ntchito inki kuyenera kuchitidwa molingana ndi izi:

1. Mulimonsemo, kutentha kwa inki kuyenera kusungidwa pansipa 20-25 ℃, kusintha kwa kutentha sikungakhale kokulirapo, apo ayi, kudzakhudza kukhuthala kwa inki ndi mawonekedwe osindikiza pazenera.

Makamaka inki ikasungidwa panja kapena kusungidwa kutentha kosiyanasiyana, imayenera kuikidwa kutentha kozungulira kuti izolowere masiku ochepa kapena kupanga inki mbiya kuti ikwaniritse kutentha koyenera. Izi ndichifukwa choti kugwiritsa ntchito inki yozizira kuyambitsa kusindikiza pazenera, ndikupangitsa mavuto osafunikira. Chifukwa chake, kuti inki ikhale yabwino, ndibwino kuti musunge kapena kusunga munthawi yazinthu zotentha.

2. Musanagwiritse ntchito, inkiyo imayenera kusunthidwa mokwanira kapena mosamala moyenera. Ngati inki mumlengalenga, gwiritsani ntchito kuyimirira kwakanthawi. Ngati pakufunika kusungunula, sakanizani bwino poyamba ndikuyesa mamasukidwe akayendedwe. Mbiya ya inki iyenera kusindikizidwa nthawi yomweyo ikatha. Nthawi yomweyo, osayikanso inki pazenera ndi inki yosagwiritsidwa ntchito yosakanikirana.

3. Wotsuka yemwe angagwiritse ntchito bwino momwe angagwiritsire ntchito ntchito amakhala ndi ukonde wowoneka bwino, ndipo amafuna kuyeretsa kwathunthu. Mukamakonzanso, ndibwino kugwiritsa ntchito zosungunulira zoyera.

4. Kuyanika kwa inki, kuyenera kukhala ndi pulogalamu yabwino yotulutsa utsi.

5. Kuti zinthu ziziyenda bwino ziyenera kukwaniritsa zofunikira za malo ogwirira ntchito pazosindikiza.

Kodi udindo wa PCB inki mu ndondomeko kupanga PCB

Inki imagwira ntchito yopanga zojambulazo zamkuwa kuti khungu lamkuwa lisaululidwe, lidzakhudza njira zotsatirazi, inki yovuta, mafuta a kaboni, mafuta a siliva, mafuta a kaboni ndi mafuta a siliva zimakhala ndi zochita, zomwe zimagwiritsidwa ntchito ngati inki , mafuta oyera, mafuta obiriwira, mafuta akuda, mafuta amtambo, mafuta ofiira, batala.
