Ngā Kai:

Ka taea te wehewehe i te pango waro mā ki te pango waro mā kua whakapūpūtia, me te pango waro mā āhua-hau, e ai ki ngā tikanga whakaputa. I raro i ngā āhuatanga noa, ko te pango waro mā āhua-hau he matūriki totoka āhua-kore, he mā, he āhua mārama (te rahi o te matūriki he iti iho i te 100nm), kāore he paitini, ā, he nui te horahanga mata motuhake. Ko te pango waro mā āhua-hau he mea hanga katoa ki te nano silica, me te parakore o te hua tae atu ki te 99% me te rahi o te matūriki he 10-20nm. Heoi, he uaua, he utu nui hoki te tukanga whakarite; ka taea te wehewehe i te pango waro mā kua whakapūpūtia ki te pango waro mā kua whakapūpūtia tuku iho me te pango waro mā kua whakapūpūtia motuhake. Ko te tuatahi e pā ana ki te hauhā silicon i hangaia me te waikawa whanariki, te waikawa hauwai, te CO2 me te karāhe wai hei rauemi mata taketake, ā, ko te tuarua e pā ana ki te hauhā silicon i hangaia me ngā tikanga motuhake pēnei i te hangarau taumaha teitei, te tikanga sol gel, te tikanga tioata matū, te tikanga tioata tuarua, te tikanga micellar micro lotion whakamuri rānei. Ko te silica kua whakapūpūtia te nuinga o te wā hei kaihoko whakapakari mō te rapa taiao me te rapa hangai, me te kaihoko waku mō te paraihe niho. Ko te silica wāhanga kohu te nuinga e whakamahia ana hei kaihoko whakapakari, hei paninga me te whakamātotoru kapia kore-māku o te rapa silicone, ā, ko te silica gel tino pai me te aerogel te nuinga e whakamahia ana hei kaihoko paninga, hei whakamātotoru, hei kaihoko whakatuwhera kiriata kirihou, me ētahi atu. Hei tāpiringa taiao me te mahi teitei, ko te pango waro ma te nuinga e whakamahia ana i roto i ngā mara o ngā hua rapa (tae atu ki te rapa silicone whakamomona pāmahana-tiketike), ngā kakahu, te hanga pepa, ngā patu pepeke, me ngā tāpiringa kai.

Whakamahinga:

Ngā hua rapa

Ka whakamahia te waro pango mā i roto i ngā hua rapa tae hei whakakapi i te waro pango mō te whakakaha, hei whakatutuki i ngā hiahia o ngā hua mā, āhua mārama rānei. He tino piripono hoki te hiraka, he ātete ki te haehae, he ātete ki te wera me te ātete ki te koroheketanga, nō reira ka taea hoki e ia te whakakapi i tētahi wāhanga o te waro pango i roto i ngā hua rapa pango hei whiwhi i ngā hua rapa kounga teitei, pērā i ngā potae o waho o te rori, ngā potae hangarau, ngā potae radial, me ētahi atu.

Ngā hua matū o ia rā

He paraihe niho mārama, he mātotoru hoki, he pango waro mā hei whakakī me te whakakoi, he pai te ngāwari me te marara, he maeneene, he ngawari te whakapiri, he pai te ātete ki te pakū, ā, kāore e waikura te tinana o te ngongo paraihe; Ka taea e ia te pupuri i te pumau o te paraihe niho rongoā. Ina koa he pai te hototahi ki te fluoride, ka taea te karo i te ngoikoretanga o ngā tote kore e rewa i hangaia e ngā tote konupūmā hei whakakoi.

Kaiwhakakī raima

Ka whakamahia i roto i ngā piripiri i hangaia ki te rapa maori, ki te rapa hangai rānei, ka whakarato i te thixotropy me te whakakaha, me te whakapai ake i te piri nā tōna ngāwari ki te totoro, kia kounga teitei ai, kia iti ai hoki te utu.

Ārai i te whakapiripiri

Ka taea te whakamahi i te waro pango mā i roto i ētahi hua hei whakapai ake i te rere o te wai, pērā i ngā tongi tarutaru, ngā patu harore, ngā mea whakakoi wira huri, ngā mea whakama horoi kakahu, te werohanga phenolic o te urotropine, ngā hua kirihou o ngā phenols me te urea, te hanga rapa whanariki me ngā ranunga ārai-whakakoi.

Whakakī pepa

Mā te whakamahi i te waro pango mā hei whakakī pepa ka taea te whakapai ake i te ātete waituhi me te kaha ā-pūkaha o te pepa, te whakanui ake i te mā, me te whakaiti i te taumaha o te pepa. Ka taea e ia te whakaiti i te mama o te pepa, te whakaiti i ngā utu whakaputa, me te whakapai ake i te mahi a te pepa.

Hei tāpiritanga, ka taea hoki te whakamahi i roto i ngā ahumahi maha pēnei i ngā kai ahi, ngā kai whāngai kararehe, ngā mea whakapaipai, ngā kai whakangaro kararehe, ngā tae, ngā peita, me ētahi atu.
