Me pēhea te hanga i te silica gel?

He momo rauemi mimiti kaha te silica gel.
He matū kore-āhua tēnei, ā, ko tōna tauira matū ko mSiO2.nH2O. E tutuki ana i te paerewa matū Hainamana HG/T2765-2005. He rauemi mata whakamaroke kua whakaaetia e te FDA ka taea te whakapā tika ki te kai me ngā rongoā. He kaha te kaha o te hiraka silica ki te wai, he kaha te mahi mimiti, ahakoa ka rumakina katoatia te hiraka silica ki roto i te wai, e kore e ngawari, e wai rānei. He āhuatanga kāore i te paitini, kāore he reka, kāore e waikura, kāore hoki e poke, nō reira ka taea te whakapā tika ki tētahi taonga. Ko ngā rauemi mata e tika ana kia whakaritea mō te hanga i te hiraka silica ko: te konutai silicate (paucine, karāhe wai), te waikawa whanariki.

Tuatahi, ka whakaritea te kawakore me te waikawa i mua, kātahi ka rewa te silicate konutai totoka i te pāmahana teitei, ka tātarihia hei whakarite i tētahi kukū wai, kātahi ka whakaritea te waikawa whanariki ki tētahi kukū wai, ko te kukū o te waikawa whanariki he 20%.

Tuarua, ko te taahiraa tuarua ko te hanga kāpia (whakapūhui ira), ko tēnei te taahiraa tino nui, ko te wairewa mirumiru me te waikawa whanariki kua whakatikatikahia i raro i ngā tikanga motuhake, kia puta ai he wairewa ira wairewa, ā, i muri i te taenga ki te kukū tika ka huri hei matūriki ira. Ka taea te whakatau katoa i te āhua me te rahi o ngā matūriki kia rite ki ngā hiahia me te kaha whakaputa a te kaiwhakamahi. Ko te tikanga noa o te whakapūhui ira ko te whakapūhui hau, ā, ko te ōwehenga waikawa-pūtake, te kukū, te pāmahana me te wā whakapūhui ira e whakamahia ana i roto i te tukanga whakapūhui ira ko ngā tawhā hangarau motuhake.

Tuatoru, me haere te kirikiri pakeke i roto i tētahi wā me te pāmahana, me te uara PH hoki kia pakeke ai, kia kaha ai te angaanga kirikiri, kia piri ai te kāpia i waenga i ngā matūriki i te wā o te koroheketanga hei hanga hononga Si-O-Si, kia kaha ake ai te kaha o te angaanga, kia tata ai ngā matūriki tetahi ki tetahi, kia whakaitihia te wāhi i roto i te hanganga whatunga, ā, kia pēhia ai te wai kei roto.

Te pīkara, te horoi, te horoi kāpia He taahiraa tino nui anō hoki te pīkara, te horoi, te horoi kāpia i roto i te tukanga, nā te mea ka horoia atu te Na2SO4 i hangaia e te kirikiri kirikiri. Whakahaerehia ia anion i roto i te awhe e hiahiatia ana e te tukanga. Ka taea te kī ko te nuinga o ngā āhuatanga o te kōhao o te kirikiri silica kua oti te hanga ka whakatauhia e te koroheketanga o te tukanga horoi rapa, ā, ko te nui o te koroheketanga o tēnei tukanga e whakawhirinaki ana ki te mahi i roto i te tukanga pīkara, horoi, me te horoi rapa.

Tuarima, whakamaroke, ka tukuna te hydrogel kua oti te whakarite (whai muri i te horoinga) ki roto i te rūma whakamaroke, i raro i ngā tikanga motuhake hei whakaiti i te nui o te wai o te gel kia maroke ki te awhe e hiahiatia ana. Ka teitei ake te pāmahana whakamaroke, ka teitei ake te tere o te kohikohinga matūriki tuatahi, ā, ka nui ake te āputa.

Ono, te tirotiro, ka whakamarokehia te mīhini whiriwhiri pōro i muri i te whakamaroke i te silicone mā roto i te mata o ngā kōhao rerekē kia rite ki te rahi matūriki motuhake, ā, i te wa ano ka pakaru te tirotiro i te silica gel.

Whitu, te whiriwhiri i te kāpia: te tango i te kiripaka i roto i te pōro heterochromatic, te tango i ngā poke, kātahi ka whakamahi i te pepa hiato kia rite ki ngā whakaritenga o te takai, ā, i muri i te hiri. Whai muri i ngā mahi o runga ake nei, ka hangaia he hua silicone.
