Whakamahinga
He wai kore tae te Ethyl silicate (TEOS), e whakamahia ana hei paninga ātete-wera, hei paninga ātete-matū, hei hononga silane, hei takawaenga hanga rauropi, hei matū mua hoki mō ngā kiriata whakatakotoranga kohu matū (CVD) SiO2 i roto i te mara haurua-ira, me ētahi atu. Ko te ira rewa o te ethyl silicate he -77℃, ā, ko tōna ira kohua he 165.5℃. He paku wairewa ki te wai, ā, he wairewa ki te etanoru me te etera.
E whakamahia ana hei rauemi ārai i roto i te umanga hikohiko, hei kaihoko tukatuka hoki mō te karāhe whatu me te matū whakakōkī.
Whakamahia mō te whakarewanga tika hei here mō ngā pokepoke onepu; Ka taea e te mata whakarewa kua rongoatia ki te kohu ethyl silicate te ārai i te waikura me te wai. Ka taea te whakamahi i te ethyl silicate hei whakakī i te mata o ngā whakarewa ki te silicon, ā, mā te rongoā i te karāhe whatu ka taea te whakanui ake i tōna whakawhiti mārama. Ka taea te whakamahi i te paura silica tino pai i puta i muri i te waikura katoa hei hanga phosphors. Ko te ethyl silicate te rauemi mata o te hinu silicone. Ka taea hoki te whakamahi i te ethyl silicate hei hanga paninga ātete wera me te ātete matū. I Hapani, 90% o te ethyl silicate e whakamahia ana hei rauemi turanga mō ngā paninga ātete-waikura (peita whai konutea).
Ko te nuinga o te wā ka whakamahia i roto i ngā paninga ātete-matū me ngā paninga ātete-wera, ngā whakarewa silicone me ngā piripiri tino tika. I muri i te waikura katoa, ka puta he paura silicon dioxide tino pai, ka whakamahia hei hanga phosphorus, ā, ka taea hoki te whakamahi hei matū matū.
Ko te Tetraethoxysilane te mea e whakamahia nuitia ana i roto i te karāhe whatu, i ngā paninga ātete matū, i ngā paninga ātete wera me ngā piripiri. Te whakarerekētanga o ngā paninga ātete-waikura Kaihoko hononga whakawhiti, kaihopu, kaihoko whakamaroke; Te hanga angaanga whakakorikori me te silica tino pai te parakore.
Ko te ethyl orthosilicate te mea e whakamahia nuitia ana i roto i te karāhe whatu, i ngā paninga ātete matū, i ngā paninga ātete wera me ngā piripiri. Te whakarerekētanga o ngā paninga ātete-waikura Kaihoko hononga whakawhiti, kaihopu, kaihoko whakamaroke; Te hanga angaanga whakakorikori me te silica tino pai rawa atu.
Ngā rauemi ārai mō te umanga hikohiko, ngā paninga, ngā kaihoko maimoatanga karāhe whatu, ngā kaiwhakapūmau, te hanga rauropi, ngā whakarewa mō te whakarite i te organosilicon
I roto i te matū kua whakauruhia e hanga ana i te H+-magadiite, ka tauhohe ki te dodecylamine hei rangahau i te karāhe koiora whakarewa whakauru. He mea whakamahi noa hei matū mua i roto i te whakarite i ngā kirikiri maroke.
Te Tākai me te Tukunga
Te tākai: 200kg e ai ki ngā whakaritenga a te kiritaki.
Tukunga: nō ngā matū noa, ā, ka taea te tuku mā te tereina, te moana me te rangi.
Taonga: he 500MTs te taonga haumaru
Te pupuri me te rokiroki
Te roa o te oranga: 24 marama mai i te rā i hangaia ai, i roto i te takai taketake kāore anō kia whakatuwheratia, rongoatia ki te wāhi matao, maroke, ā, kāore e taea te ārai i te rā tika, i te wai rānei.
Whare putunga hauhautanga, Whakamaroke pāmahana iti, Wehea mai i ngā waikura me ngā waikawa.
