Kei te rapu tonu te umanga pepa i ngā huarahi hei whakapai ake i te kounga o te pepa me te whakaiti i ngā utu whakaputa. Kua noho te hauhāora silicon (hauhāora silicon/pango waro mā/silica) hei tāpiri nui ki te hanga pepa nā tōna hanganga ā-tinana ahurei me ōna āhuatanga matū. Ko ōna matūriki porowhita nano-tauine, me te horahanga mata motuhake e neke atu ana i te 200 m²/g, ka taunekeneke i te taumata ngota ngota me ngā muka pepa, ka taea ai te whakapai ake i ngā mahi maha. Ka taea te whakamahi hei whakakī, hei tae paninga, hei kaihoko rahi i roto i te tukanga hanga pepa, ka whakapai ake i te kaha, te maeneene, me te āheinga tā o te pepa. Ahakoa he pepa paninga kounga teitei mō te tā, he pepa kiko ngohengohe rānei mō te whakamahinga o ia rā, ka taea e te pango waro mā te whai wāhi nui ki te whakapai ake i te mahi hua.

Ka pāngia tā mātou pepa pango waro mā kua whakapūpūtia e te tukanga hanga waiariki motuhake, kia rite ai te rahi o te matūriki ki te 20-30nm. Mā tēnei hangarau tika ka whakaitihia te taratara o te mata o te paninga ki raro iho i te 0.5μm, ka rite te mata maeneene ki te whakaata o te pepa paninga. I te wā e tā ana, ka taea te mimiti ōrite i te waituhi, ka karohia ngā raruraru pēnei i te pōuri o te waituhi me te tae koretake. I whakahaerehia e tētahi kaihanga pepa tā matua i Hapani he whakamātautau e ono marama te roa, me te tāpiri i te 10% o tā mātou pepa pango waro mā ki tā rātou tauira paninga pepa paninga. He mea whakamiharo ngā hua: he pikinga 25% o te kanapa o te pepa, he whakapainga 15% o te whakamāramatanga tā, me te pikinga 20% o te tere maroke o te paninga, he pai ake te pai o te whakaputa. I tua atu, i piki ake te ātete o te pepa ki te pakū mā te 18%, ka roa ake te ora o te pepa, ā, ka whakarei ake i tōna whakataetae mākete.

Mō te pepa kiko, ko te ngawari me te kaha ngā tohu matua e rua e aro nui ana ngā kaihoko. He maha ngā wā ka raru te pepa kiko tuku iho i te ngoikore o te kaha—he ngāwari ki te pakaru ina mākū. Mā te tāpiri i te nui o te waro pango mā ki te penupenu pepa kiko ka taea te whakatau i tēnei raruraru. Nā te nui o te mata motuhake o te waro pango mā ka taea e ia te hanga hononga hauwai me ngā muka cellulose i roto i te penupenu, ka whakarei ake i te kaha here i waenga i ngā muka. Ina 1-2% te nui o te tāpiri, ka taea te whakanui ake i te kaha kume maroke o te pepa kiko mā te 10%, ā, ka taea te whakanui ake i te kaha kume maku mā te 15%, engari kāore te ngawari o te pepa kiko e pāngia. Nā te mea ka taea e ngā matūriki tino pai o te waro pango mā te whakakī i ngā āputa i waenga i ngā muka me te kore e hanga he hanganga mārō, kia mau tonu ai te ngohengohe me te whakamarie o te pepa kiko ki te whakamahi.

I whakauruhia e tētahi waitohu pepa kiko Pākehā tā mātou pepa pango waro mā ki roto i tā rātou raina whakaputa, ā, i whakahaerehia e rātou he whakamātautau matapo mō ngā kaihoko. I whakaatuhia e ngā hua e 82% o ngā kaihoko i pai ake ki te hua kua whakapaitia, me te kī he kaha ake tōna me te ngawari kāore i rerekē. Nō reira, i tino mihia ā rātou hua e ngā kaihoko, ā, i piki ake ngā hoko mā te 30% i roto i te haurua tau. I whakaatuhia e ētahi atu tātaritanga ko te tāpiri o te pepa pango waro mā i whakapai ake i te ātete o te pepa ki te kōwhai, me te pupuri i tōna mā mō te wā roa.

I roto i te hanga pepa motuhake pēnei i te pepa tātari me te pepa whakamahana hiko, ka whakamahia katoatia hoki ngā āhuatanga ahurei o te pango waro mā. Me pai te pūngao me te kaha mimiti o te pepa tātari mō te maimoatanga wai. Mā te tāpiri i te silica paowa me te rahi matūriki o te 5-10nm ki te penupenu pepa tātari ka taea te whakanui ake i te pūngao o te pepa mā te 20%. He kaha te kaha mimiti o ngā matūriki silica mō ngā poke pēnei i ngā katote konganuku taumaha me ngā mea rauropi i roto i te wai, ka nui ake te whai huatanga tātari o te pepa tātari, ā, ka taea e te tika tātari te eke ki te 0.1μm.

I roto i tētahi kaupapa whakamātautau me tētahi kamupene horoi wai, i whakamahia tā mātou silica kua kohuhia ki te hanga pepa tātari. I whakaatuhia e ngā hua kua piki ake te tere tango i ngā katote konganuku taumaha mai i te 75% ki te 92%, ā, kua piki ake te tere tango i ngā poke rauropi mā te 25%. I tutuki te kounga o te wai kua rongoatia ki ngā paerewa wai inu o te ao tino pakari.

Me kaha te kaha o te pepa whakamahana hiko, ā, me ātete hoki ki te wera. Mā te tāpiri i te waro pango mā kua whakapūtātia ki te parakore (he nui te SiO₂ ≥99.9%) ki te penupenu pepa whakamahana, ka taea te whakapai ake i te kaha o te kaha o te pepa mai i te 15kV/mm ki te 25kV/mm, me te whakanui ake i te taumata ātete wera mai i te Akomanga A (105°C) ki te Akomanga B (130°C), kia pai ai te whakamahi i roto i ngā taputapu hiko ngaohiko teitei.

I mahi tahi tā mātou kamupene me tētahi kaihanga whakawhiti hiko ki te whakamātautau i te mahi a te pepa whakamahana me tā mātou pango waro mā. I muri i te 1000 hāora o te mahi tonu i te 120°C, i mau tonu te mahi whakamahana hiko pai rawa atu o te pepa whakamahana, me te kore he hekenga nui o te kaha hiko. Nā tēnei putanga hou i taea ai e te kaihanga te whakawhanake i tētahi whakatupuranga hou o ngā whakawhiti hiko tino pai, me te whakaiti i ngā ngaronga pūngao mā te 12%.

He maha ngā momo hua pango waro mā e tukuna ana e tā mātou kamupene mō te umanga pepa, tae atu ki ngā taumata marara-teitei, te parakore-teitei, me ngā taumata tino-pai. Kua arotauhia ia taumata mō ngā tukanga hanga pepa—hei tauira, he iti te uara mimiti hinu o tā mātou pango waro mā kua pania (≤150ml/100g), ka taea te whakaiti i te nui o te here e whakamahia ana i roto i te paninga, ka whakaiti i ngā utu whakaputa; he pai te wairewa o tā mātou pango waro mā kua pania ki te pepa kiko, ka whakarite kia taurite te mararatanga ki roto i te penupenu. Ka tutuki i ā mātou hua katoa ngā whakaritenga tiaki taiao o te umanga pepa, kāore he konganuku taumaha, he matū kino rānei, ā, ka taea te pirau i roto i te taiao tūturu, ka whakaiti i te parahanga taiao.

Mō ngā mahi kawe taonga, ka taea e mātou te whakarato i ngā takai nui (500kg/pēke) me ngā takai iti (25kg/pēke) e ai ki ngā hiahia o te kiritaki, ā, ka mahi tahi mātou me ngā kamupene kawe taonga ngaio kia tika ai te tuku i ngā hua ki te wheketere o te kiritaki i roto i te wā tika me te haumaru. Kei te wātea tā mātou tīma ratonga muri-hoko 24/7 ki te whakatika i ngā take e pā ana ki te hua, kia kore ai e manukanuka ngā kiritaki.
