Mapangidwe a Conductive Adhesive

Nthawi: 2020-07-23

Conductive zomatira ndi zomatira zokhala ndi madulidwe ena pambuyo pochiritsa kapena kuyanika. Ikhoza kugwirizanitsa zipangizo zosiyanasiyana zopangira pamodzi kupanga njira yamagetsi pakati pa zipangizo zogwirizanitsa. M'makampani amagetsi, zomatira zomangira zakhala chinthu chofunikira kwambiri.


Kodi zomatira zomatira zimayendetsa bwanji magetsi?


Kulumikizana pakati pa conductive particles kumapanga njira yoyendetsera, yomwe imapangitsa kuti conductive zomatira zikhale zochititsa chidwi. Kulumikizana kokhazikika pakati pa tinthu tating'onoting'ono tomatira kumayambitsidwa ndi kuchiritsa kapena kuyanika kwa zomatira za conductive. Pamaso pa zomatira conductive anachiritsidwa kapena zouma, ndi conductive particles anapatukana mu zomatira, ndipo palibe mosalekeza kukhudzana wina ndi mzake, kotero iwo ali insulating boma. Pambuyo zomatira conductive ndi kuchiritsidwa kapena zouma, buku la zomatira likucheperachepera chifukwa volatilization wa zosungunulira ndi kuchiritsa zomatira, kuti conductive particles ali khola mosalekeza boma ndi mzake, motero kusonyeza madutsidwe.


Chomatira cha conductive ndi chiyani?


   Conductive zomatira makamaka wopangidwa ndi utomoni masanjidwewo, conductive particles, dispersing zina, wothandiza wothandizira, etc. Masanjidwewo makamaka monga epoxy utomoni, acrylate utomoni, polychloroester, etc. , yomwe imatha kuyendetsa magetsi kudzera mu ma elekitironi kapena ma ion, ma conductivity a mtundu uwu wa zomatira zopangira amatha kufika pamtunda wa semiconductors, ndipo sangakhale ngati zitsulo. Kukana kotsika komweko kumapangitsa kuti zikhale zovuta kuchita nawo kugwirizana kwa conductive. Zambiri mwazomatira zomwe zimagwiritsidwa ntchito pamsika ndi mtundu wa filler.

   Matrix a utomoni wa zomatira zamtundu wa filler, kwenikweni, amatha kugwiritsa ntchito mitundu yosiyanasiyana ya zomatira za utomoni, zomatira zomwe zimagwiritsidwa ntchito nthawi zambiri monga epoxy resin, resin silicone, polyimide resin, phenolic resin, zomatira monga polyurethane ndi acrylic resin. Zomatira izi zimapanga mawonekedwe a mamolekyu a zomatira zomatira pambuyo pochiritsa, zimapereka mawonekedwe amakina ndi chitsimikizo cha magwiridwe antchito, ndikupangitsa kuti tinthu tating'onoting'ono timene tipange mayendedwe. Popeza utomoni wa epoxy ukhoza kuchiritsidwa kutentha kwa firiji kapena pansi pa 150 ° C, ndipo umakhala ndi mapangidwe olemera komanso mapangidwe ake, zomatira za epoxy-based conductive zimalamulira.

    Guluu wa conductive amafuna kuti tinthu tating'onoting'ono timene tizikhala ndi madulidwe abwino komanso kukula kwa tinthu kuyenera kukhala koyenera, ndipo chitha kuwonjezeredwa ku matrix opangira guluu kuti apange njira yoyendetsera. The conductive filler imatha kukhala ufa wa golide, siliva, mkuwa, aluminiyamu, zinki, chitsulo, faifi tambala, graphite ndi zina zopangira ma conductive.

   Chinthu china chofunika kwambiri mu zomatira conductive ndi zosungunulira. Popeza kuchuluka kwa conductive filler anawonjezera osachepera 50%, mamasukidwe akayendedwe a utomoni masanjidwewo a zomatira conductive kwambiri kuchuluka, amene nthawi zambiri zimakhudza ntchito ntchito zomatira. Pofuna kuchepetsa mamasukidwe akayendedwe ndi kukwaniritsa manufacturability wabwino ndi rheology, kuwonjezera kusankha otsika mamachulukidwe utomoni, nthawi zambiri kofunika kuwonjezera zosungunulira kapena zotakasika diluents. Ma resin diluent amatha kugwiritsidwa ntchito mwachindunji ngati matrix a resin pochiritsa machiritso. Ngakhale kuchuluka kwa zosungunulira kapena zotakasika diluent si lalikulu, ndi mbali yofunika kwambiri mu zomatira conductive, osati zimakhudza madutsidwe, komanso zimakhudza mawotchi katundu anachiritsa mankhwala. Zosungunulira zomwe zimagwiritsidwa ntchito nthawi zambiri (kapena zosungunulira) ziyenera kukhala ndi kulemera kwakukulu kwa mamolekyu, kusinthasintha pang'onopang'ono, ndipo mawonekedwe a mamolekyu azikhala ndi ma polar monga magawo a carbon-oxygen polar. Kuchuluka kwa zosungunulira zomwe zawonjezeredwa ziyenera kuyendetsedwa mkati mwamtundu wina kuti zisakhudze ntchito yonse ya zomatira za conductive.

   Kuphatikiza pa utomoni masanjidwewo, conductive fillers ndi diluents, zigawo zina za zomatira conductive ndi chimodzimodzi monga zomatira, kuphatikizapo crosslinking wothandizira, coupling wothandizira, preservatives, toughening wothandizira ndi thixotropic wothandizira.

bwanji Xianglong Keypad conductive phulusa?

 Rabara ya conductive imapangidwa ndi mphira wachilengedwe wa silicon, womwe sumva kuvala, dzimbiri komanso ukalamba, ndi zina. Kuthamanga kwa batani kumatha kufika 180-200g.
