Te here PTFE

Te whakamahi sima epoxy, te whakapiri ranei mo te hiri polymer ki te karaehe me te whakarewa, ki a ia ano.

Ko te parenga o te polytetrafluorethylene (PTFE) ki tetahi ahua o te piri he mea rongonui, he maha tonu te whaihua pera me tona koretake matū.Engari ko enei huanga he raru nui, ko te polymer he uaua ki te hono pono ki etahi atu rawa, ki a ia ano.He otinga mo tenei raruraru i kawea ki te kaituhi e te kamupene ko Reltek te ingoa.(He korero ano mo ratou kei raro nei).Ko te otinga o te raru ko te Sodium Naphthalide kua memeha i roto i te 2-Methoxyethyl Ether ranei i Tetrahydrofuran.Ka whakamahia tenei hei whakakoi hei whakakapi i nga ngota fluorine i runga i te mata ki tetahi momo ngota rapoi tauhohe me te here.Whai muri i te tarai i te mata polymer ka nui ake te whakaae ki nga momo sima, tae atu ki nga taapiri kapia epoxy penei i te Araldite, ko nga Reltek Epoxy Resins motuhake ake ranei.He maamaa noa te tarai me te whakauru i te mata polymer kua taratara, kua whakahekehia ki te wairewa o te Sodium Naphthalide mo te 2 meneti ka horoi i te mata kua mau ki te Isopropanol.Ko te mata taraihia he pumau me te atete miihini me te hono.Ko te uaua anake ko te hanga me te whakahaere o te Sodium Naphthalide complex.

Ko te Sodium Naphthalide he kaihoko whakaheke tino kaha, a he tere te urupare ki te Oxygen hau me te wai.Ko nga whakaaturanga nui ki te hau ka tere te whakakore.He pai rawa te hanga me te whakamahi i roto i te pouaka karapu i raro i te hauota me te whakamahi hangarau Scklenk ranei.

I roto i te whakaritenga i mahia e te kaituhi, 2.5 gm o Naphthalene (GPR Rectapur) i rewa i roto i te 25 ml o Tetrahydrofuran i roto i te ngongo Schlenk.Ki tenei ranunga 0.2 karamu o te konganuku konutai katahi ano ka tapahia.Ko te waahi-rangi i roto i te ngongo Schlenk i purea ki te Argon ka hiritia ki te aukati Subeal.I katia te pa o te taha, ka rukuhia te ngongo schlenk ki roto i te kaukau wai i te 45C mo te tekau ma rua haora.

I te wa e whakamahia ana, he pai te whakahaere i te Sodium Naphthalide i roto i te ngongo Schlenk, i roto ranei i te pouaka karapu me te tuku Nitrogen, Argon ranei he pai ki te aukati i te waiora reagent i te wa e raweke ana.He whakaritenga mo te tarai i nga ngongo polymer angiangi hei hiri ki te kowiri tira, ki te ngongo karaihe ranei.

Ka hiritia te ngongo polymer ki te wetewete ki te pito kia kore ai te wawata o te etchant, ka kuhu ki roto i te kohao o te ngira hypodermic e werohia ana te subaal.Ko te Subacial he katinga tino pai na te mea ka taea e ia te kawe i nga ngongo maha o nga diameter rereke.Ko te tikanga ko nga ngongo tino whanui (tae atu ki te 6mm od) ka taea te tarai penei.
