Tāpirihia ngā kongakonga silicone kua horoia, kua horoia ki roto i tētahi taputapu tirotiro, ā, ka whakarōpūtia kia rite ki te rahi o te matūriki me ngā rerekētanga mātotoru. Mā tēnei mahi ka taea te tango i ētahi poke kāore e tutuki i ngā whakaritenga, pērā i ngā kongakonga kirihou, ngā matūriki whakarewa, me ētahi atu, ā, ka pai ake te parakore o te silicone. Ka taea te whakarōpū anō i ngā matūriki gel silica kua tirotirohia kia rite ki te rahi me te parakore mō te tukatuka anō me te whakamahi anō.

(IV) Te whakatōtō me te purenga
Ka whakanohoia ngā matūriki tiēre silica kua tirotirohia, kua whakarōpūtia ki roto i te ipu whakarewa kia rite ki tētahi ōwehenga taumaha, me te waikawa whanariki, te waikawa dodecylbenzene sulfonic me ētahi atu matū hei whakamahana me te whakarewa. Tuatahi, ka whakamahanahia te ipu whakarewa ki te pāmahana tuatahi kua whakaritea (pēnei i te 100 nekehanga) kia kore ra ano e puta te wai whakarewa; kātahi ka tangohia te wai whakarewa ka whakamahanahia ki te pāmahana tuarua kua whakaritea (pēnei i te 250 nekehanga) kia kore ra ano e puta te wai whakarewa hei whiwhi i te wai parakore tuatahi. Kātahi ka whakamataohia te wai parakore tuatahi, ka tāpirihia he whakakorikori kawakore kore-waro (pēnei i te konutai kāponāte, te konutai paikāponāte, te konutai hauwaiwai, te pāhare pākawa rānei), ā, ka whakanuia te pāmahana ki te 130 ki te 160 nekehanga mō te whakarewa tuarua kia kore ra ano e puta te wai whakarewa hei whiwhi i te wai parakore tuarua.

(V) Te mimiti me te tātari
Ka whakamataohia te wai parakore tuarua, kātahi ka tāpirihia he mea mimiti (pērā i te waro whakahohe). Kia nui te whakaoho, ka tātarihia hei tango i ngā paru me ngā matū toenga i roto kia puta ai he hua silica gel parakore. Mā tēnei mahi ka taea te whakapai ake i te parakore me te kounga o te silicone, kia tutuki ai ngā paerewa mō te tukatuka anō me te whakamahi anō.

(I) Te hiranga o te taiao
He mea nui te hangarua o ngā kākahu o roto silicone ki te taiao. Tuatahi, ka āwhina i te whakaiti i te whakaputanga o ngā para me te whakaiti i te parahanga ki te taiao. He uaua ki te pirau ngā rauemi silicone i roto i te taiao tūturu. Ki te makahia atu i te wā e hiahiatia ana, ka pāngia te oneone, ngā puna wai, me ētahi atu. Mā te hangarua, ka taea te huri i ēnei para hei rauemi whai hua, ka whakaiti i te whakamahinga me te whakamahinga o ngā rauemi tūturu. Tuarua, mā te hangarua o ngā kākahu o roto silicone ka taea te penapena pūngao me te whakaiti i ngā tukunga waro i roto i te tukanga whakaputa. I roto i te tukanga whakaputa silicone, he nui te pūngao e pau ana, ā, mā te hangarua ka taea te whakaiti i te hiahia mō te hanga silicone hou, ā, ka whakaiti i te whakamahinga pūngao me ngā tukunga hau kati kōtuhi, ā, he pānga pai ki te whakaiti i te huringa āhuarangi o te ao.

(II) Ngā Wero
Ahakoa he maha ngā painga taiao o te hangarua o ngā kākahu o roto silicone, he maha ngā wero kei roto i te tukanga whakahaere. Tuatahi, he uaua te kohikohi me te whakarōpū i ngā kākahu o roto silicone. Nā te whānuitanga o te whakamahinga me te tohatoha marara o ngā kākahu o roto silicone, he nui te tangata, ngā rauemi rauemi me te wā e hiahiatia ana hei kohikohi. I taua wā anō, he rerekē te hanganga me te hanganga o ngā momo kākahu silicone, ā, me whakarōpū tika, ka nui ake te uaua me te utu o te hangarua. Tuarua, kāore anō kia pakari te hangarau hangarua o ngā kākahu o roto silicone. I tēnei wā, kāore anō kia tino tika ngā tikanga hangarua me te maimoatanga o ngā kākahu o roto silicone, ā, he maha ngā arai hangarau, pērā i te nui o te kaha e pau ana i roto i te tukanga hangarua me te kounga kore pumau o ngā hua hangarua, e aukati ana i te whanaketanga o te umanga hangarua kākahu o roto silicone. Hei tāpiri, he iti te mōhiotanga me te whai wāhi a te marea ki te hangarua o ngā kākahu o roto silicone, he mea nui anō hoki tēnei e pā ana ki te pānga hangarua. He maha ngā tāngata kāore i te mārama ki te hangarua o ngā kākahu o roto silicone, ā, kāore e mōhio me pēhea te maka tika i ngā kākahu o roto silicone kua makahia, ka hua ake he nui ngā rauemi hangarua e maumauria ana.

V. Te Tirohanga ā-Mārama
I te haere tonu o te whanaketanga o te pūtaiao me te hangarau, me te whakapai ake i te mōhiotanga taiao pāpori, ka whānui ake te tirohanga whanaketanga mā te hangarua o ngā kākahu o roto silicone. I tētahi taha, ka haere tonu ngā kairangahau ki te whakawhanake i te hangarau hangarua o ngā kākahu o roto silicone he pai ake, he pai ake hoki mō te taiao, me te whakaiti i ngā utu hangarua me te whakapai ake i te kounga me te mahi a ngā hua hangarua. Hei tauira, tūhuratia ngā tikanga hangarua ā-tinana hou, pērā i te kuru pāmahana iti me te tango wai supercritical, hei whakaiti i te whakapaunga pūngao me te whakamahinga o ngā matū matū i roto i te tukanga hangarua; whakawhanake i ngā hangarau hangarua matū matatau, pērā i te pakaru catalytic me te polymerization aronga, hei whakatutuki i te huringa me te whakamahi anō i ngā rauemi silicone. I tētahi atu taha, ka whakanui ake te kāwanatanga me ngā rāngai katoa o te hapori i tā rātou tautoko mō te hangarua o ngā kākahu o roto silicone, ka whakatakoto kaupapa here me ngā ture e tika ana, ka whakataurite i te tikanga mākete hangarua, me te whakapai ake i te mōhiotanga me te whai wāhi a te marea ki te taiao. Hei tauira, whakauru i ngā kaupapa here tautoko hei whakatenatena i te hangarua o ngā kākahu o roto silicone, te ārahi i ngā umanga ki te whai wāhi kaha ki te hangarua; te whakapakari i te pānuitanga me te mātauranga tiaki taiao, te whakapai ake i te mōhiotanga o te marea ki te hiranga o te hangarua o ngā kākahu o roto silicone, te tautoko i ngā ariā kai matomato, me te whakatairanga i te whanaketanga pumau o te umanga hangarua o ngā kākahu o roto silicone.

I roto i te poto, he mea nui te hangarua o ngā kākahu o roto silicone hei tiaki i te taiao, e kore e āwhina noa ki te whakaiti i te whakaputanga o ngā para me te parahanga taiao, engari ka penapena rauemi me te pūngao, ā, ka tutuki ai te whanaketanga ōrite o te ōhanga me te taiao. Ahakoa kei te mau tonu ētahi wero i roto i te tukanga hangarua, ka āta whakatauhia ēnei raruraru me te whanaketanga o te hangarau me te hapori. He take tā tātou ki te whakapono ā tōna wā, ka nui ake te rongonui me te tino pai o te hangarua o ngā kākahu o roto silicone, ā, ka nui ake te takoha ki te tiaki i te taiao o te ao me te hanga i tētahi kāinga ataahua.
