Waikawa Silicic me tona tono
waikawa Silicic takahi ko te pūhui o silicon waikura , me te wai. Ai e taea e te ōwehenga o ona wāhanga hei tino momo. Na reira, i roto i te whānui taea te māngai tona hanganga i te tātai. I roto i tenei take waikawa silicic ki te aroaro o moni rerekē o te takawai waikura me te wai, e ko, ki uara rerekē o te tawhā n me m, e taea ngāwari neke i tetahi āhua ki tetahi. Ko te kupu, n me te m i roto i tenei take e taea te i titiro rite taurangi.
I roto i te ariā, e taea te rite waikawa silicic mā te tauhohe i te magnesium o te whakarewa alkali (hei tauira konutai) me te "kaha" waikawa (hei tauira, te waikawa pūhaumāota). I roto i tenei ara, kua taratahi i roto i te āhua free (rite), etahi o enei waikawa: metasilicic, orthosilicic me etahi atu. Hei tauira, he tauhohenga matū whakaputa waikawa metasilicic:
+ 2HCl = + 2NaCl
Heoi, ki te whiwhi i te waikawa silicic parakore he tata e taea. I roto i te wairewa waiwai (me e whiwhi ratou supersaturated) waikawa silicic i roto i te tukanga polymerization mutu pūtake hanganga o rongoā colloidal ki te wā, kaua poto o te oraraa. Atu enei rongoā o te rā i hanga e te coagulation. Reira takoto te whakamahi o te waikawa silicic, mai i te tatau nau rā ki te hoatu i te takawai pera-ka karanga, whakamahia nei te rite te desiccant me absorbent. I tua atu, mā te whakamahi i stabilizers motuhake, rite i rongoā colloidal colloids pūmau (sols ranei) e kitea ano tono i roto i te hanga.
Ko ruarua wairewa, thermally iu me te ngoikore waikawa Silicic. A, no te wera, te whāwehe o te waikawa silicic whakahuatia nei e te tauhohenga matū e whai ake nei:
=
Ko reira ano hoki te waikawa ngoikore atu te waro taua. Na roto i te viivii ore o tenei waikawa silicic i roto i wairewa waiwai ngā te waikawa carbonic i ona tai ngā. Ka rite ki te tauira, ka taea te kite i te reira i roto i te tauhohe:
= +
E huaina tai waikawa Silicic silicates. E ratou he tohatoha whānui i roto i te natura. Hei tauira, i roto i te kirinuku o te whenua te nuinga ngā o silicas me silicates. Ko ētahi o ēnei wherepāra, ngā uku, Mika, talc, me te tini ke atu. E ngā Silicates i te hanganga o te toka - ofa'i, te karā, me ētahi atu. tioata magnesium He pera kohatu pai-mohiotia, whakaaro nei, no te mea o ratou rarity me ataahua te utu nui rite emerara, he topaha, me te aquamarine.
Te nuinga o nga silicates rewa i roto i te wai. Ko te okotahi anake he silicates te konutai me te pāhare pāporo. Ka taea te whiwhi ratou i te alloying ki te waihā hāngai pākawa ranei. Hei tauira,
+ + =
E mohiotia wairewa waiwai o te tai i whiwhi i roto i tenei ara kia rite ki "waterglass". kitea e te reira i te whakamahi whānui rite i tētahi ruruku i te hanga o te raima waikawa-ātete, me i tua atu, e whakamahia ana i roto i te hanga o te putty me pepa katoa kāpia mohiotia. Ka rite ki te retardant mura me te parewai impregnating ratou hua tukatuka hoki i hanga o papanga, rakau, me te pepa.
Silicates, hei wāhanga o e reira he konumohe, riro whakaingoa aluminosilicate. ngā Mika, me te wherepāra enei, ahakoa he nui atu uaua ratou hanganga. Ko te kupu, te wherepāra, anake silicon waikura, me te konumohe ōkai hoki kei waikura o te konutai, pāhare pāporo, me te konutai. I roto i te hanganga o te Mika, i roto i te tua ki te konumohe, me te silicon, te mea he hauwai, te konutai pāhare pāporo ranei, engari kia waiho, ahakoa iti noa, ano konupūmā, konupora rino ranei.
I roto i te whānui, i te whakamahi o silicates i roto i te āhuatanga hakari he tino whanui, me te kanorau. E whakamahia toka Mountain magnesium rite rauemi hanga. Silicates whakamahia rite te rauemi raw i roto i raima ahumahi, ngā taima, okouku, karaihe, a pera atu. Mika, me te papa kiripaka e whakamahia mo te hanga o ngā rauemi tuuraa i waiariki, me te hiko.
