Ko te whakapiri i te mate ko te whakapiri me etahi whanonga i muri i te rongoa ki te whakamaroke ranei. Ka taea e ia te hono atu i te maha o nga taonga whanonga hei hanga i tetahi huarahi hiko i waenga i nga taonga honohono. I roto i te umanga miihini, kua whakapakeketia te ahunga whakamua.


Me pehea te hiko hiko whakapiri hiko?


Ko te hono tahi i waenga i nga matūriki whanonga he ara kondukino, na reira ano te kakano whanonga. Ko te whakapumautanga pumau i waenga i nga matūriki kei roto i te paparanga piri na te rongoa i te maroke o te taapiri whakahaere. I mua i te rongoa o te paparanga whakahaere, ka maroke ranei, ka wehea nga matūriki takahuri i roto i te whakapiri, kaore he panui haere tahi me o raatau, na reira kei roto i te tuuturu. I muri mai i te rongoa o te whakapiri ki te rongoa, ka maroke ranei, ka heke te kaha o te papatairite na te huringa o te whakarewa me te rongoa o te whakapiri, kia mau tonu nga matūriki whanonga ki te noho pumau tonu tahi i a ratau, koia te whakaatu i te whanonga.


He aha te hanganga matua o te whakapiri whakahaere?


   Kei te nuinga o te urupare uruparenga o te haehae resin, matūriki whanonga, marara taapiri, kaiwhakatuma awhina, me era atu mea. Ko te matika kei te nuinga o te epoxy resin, resin acrylate, polychloroester, me etahi atu ahakoa ko te hanganga o nga polymers tino honohono he whanonga ano, penei i nga hanganga pyridine macromolecular , ka taea e te hiko te hiko i roto i te irahiko, i te ngota ranei, ko te whanonga o tenei momo taapiri whakahaere ka tae noa atu ki nga taumata o te semiconductors, a kaore e rite ki nga konganuku. Ko te taua ātete iti e uaua ana ki te takaro i te mahi o te hononga whanonga. Ko te nuinga o nga putea taatai ​​e whakamahia ana i te maakete he momo whakakiipa.

   Ko te taarua o te urunga o te taapiri-whakahaere a te kaiwhakapiki, na te tikanga, ka taea e koe te whakamahi i nga momo momo tohu matotoru, te momo waipuna thermosetting e whakamahia ana, penei i te tarapara epoxy, he whakarewa silicone, te polyimide resin, te taraiwa tipua, nga pūnaha whakapiri pēnei i te polyurethane me te resry acrylic. Ko enei taapiri he hanga te hanganga anga hiwi o te kati taatai ​​ki te whakaora, ki te whakarato i nga waahanga miihini me te taurangi o nga mahi whakahoahoa, ka taea ai nga matū whakakapi kapi ki te hanga ngatahi. Mai i te mate epoxy ka taea te rongoa i te pāmahana rūma, i raro ranei o te 150 ° C, me te whai kiko o te hanga me nga hoahoa hoahoa, ka kaha te haangai o te haahi epoxy.

    Ko te kapi haangai e hiahia ana ko nga matūriki whanonga he pai te whanonga me te rahinga matūriki kei roto i te waahanga whaitake, ka taea te taapiri atu ki te kara kakano whanake hei hanga i tetahi ara whanonga. Ka taea e te kaihiko kapi te paura koura, hiriwa, parahi, konumohe, konutea, rino, te tueke, te whakaahua me etahi taangata whakahaere.

   Another important component in conductive adhesive is solvent. Since the amount of conductive filler added is at least 50%, the viscosity of the resin matrix of the conductive adhesive is greatly increased, which often affects the process performance of the adhesive. In order to reduce viscosity and achieve good manufacturability and rheology, in addition to selecting low-viscosity resins, it is generally necessary to add solvents or reactive diluents. The reactive diluents can be directly used as the resin matrix for reaction curing. Although the amount of solvent or reactive diluent is not large, it plays an important role in the conductive adhesive, not only affecting the conductivity, but also affecting the mechanical properties of the cured product.      Commonly used solvents (or diluents) should generally have a larger molecular weight, slower volatilization, and the molecular structure should contain polar structures such as carbon-oxygen polar segments. The amount of solvent added should be controlled within a certain range so as not to affect the overall performance of the conductive adhesive.

   I tua atu ki te koikoi resin, ki te whakakiu me nga waerere, ko etahi atu waahanga o te whakapiri conductive he rite ano ki nga koikoi, tae atu ki nga taapiri hono, nga taapiri hono, taawana, nga hoapene whakahiato me nga kaihoko thixotropic.

Kia pehea te e pā ana ki Xianglong Keypad's ngoikore?

 Ko te rapa whakahaere he mea hanga mai i te rapa rino maori, he mea mau tonu ki te whakakakahu, ki te ruuma me te koroheke, me nga mea. Ka tae atu te paato o te pihi ki te 180-200g
