Kua whakarōpūtia te waro pango mā (te hauhā silica) ki roto i ngā takawai (āhua-kohu) me ngā takawai whakarewa (āhua-wai), he rerekē ngā āhuatanga me ngā whakamahinga o ia takawai.
Hiraka kua whakapūpūtia
Ko te silica kua whakapūpūtia, i hangaia mā te waikura pāmahana teitei o ngā chlorosilanes i roto i te mura hauwai-hāora, e whakamanamana ana ki te parakore ≥99.8%, ngā matūriki tuatahi nanoscale (7–40 nm), me te horahanga mata motuhake tino teitei (100–400 m²/g). Ka hangaia he whatunga thixotropic pakari, e tuku ana i te whakakaha tino pai, te pumau wera, me te whakamarumaru hiko. He pai mō ngā tono teitei, he kaihoko whakakaha nui i roto i ngā rapa silicone, he whakarerekētanga rheology i roto i ngā paninga/piripiri hei ārai i te totohu, me te tāpiri matua i roto i ngā whakapaipai, ngā encapsulants hiko, me ngā rauemi pākahiko.
Te Hiraka Whakapūngao
Ko te silica kua whakapūpūtia, i hangaia mā te whakakore i te silica konutai ki te waikawa (hei tauira, H₂SO₄) ā, muri iho ka whakapūpūtia me te whakamaroke, he āhua parakore tata ki te 93%, he nui ake ngā matūriki kua whakapūpūtia (tauine maikoroni), me te horahanga mata motuhake taurite (100–200 m²/g). He iti te utu, he ngāwari hoki te tukatuka, he tino pai i roto i ngā āhuatanga utu-iti. He whānuitia te whakamahinga hei whakakī whakakaha i roto i ngā potae (whakaiti i te ātete hurihuri) me ngā hua rapa, hei kaihoko whāriki i roto i ngā peita, hei kaihoko waku i roto i te paraihe niho, me te kaihoko kawe/ārai-pupuhi i roto i ngā tāpiringa kai me te whāngai kararehe.

Rerekētanga Matua: Mahi me te Utu
Ko te rerekētanga matua kei roto i te mahi me te utu:silica kua kohue tuku ana i te kaha me te pumau tino pai mō ngā tono mahi teitei i te utu nui ake, i te measilica kua pupū akeKa tukuna he mahi pono i te utu iti iho mō ngā hiahia whānui. Mā te whiriwhiri i te momo tika ka arotau i te mahi a ngā rauemi, ka whakataurite i ngā utu, ā, ka hāngai ki ngā whakaritenga tono motuhake.
Mā tēnei tuhinga ka whakaratohia he tirohanga whānui hei āwhina i a koe ki te whiriwhiri i te silica tino tika mō ō kaupapa.
