Kapia karaehe Silicone me te piriona mica silicone atete teitei.
Ko Huo Changshun me Chen Rufeng mai i Chenguang Chemical Research Institute, Manatū o te ahumahi matū, me etahi atu kei te whakawhanake i te kapia karaihe silicone me te whakapiri mica teitei i Haina.I te mutunga o nga tau 1970, cts-103 silicone resin, e mohiotia ana ko "silicone glass resin", i pai te whakawhanakehia e te hydropolycondensation o te methyltriethoxysilane i te aroaro o te waikawa waikawa.I whakamahia te kapia ki te maimoatanga o te pepa matatau, te whakamarumaru o te mata whakarewa, me te honohono o te pepa mica, paura mica ranei i te timatanga.I te tau 1980, i whakamahia e Sanhua, Xue Zhiqing me Li Yansheng, nga kaihanga kapia i Shanghai, te kapia whakawhiti katote totoka hei whakakorikori waikawa rangitahi.Ko nga kapia silicone maramara me te kakahu-atete o sar-1 me sar-2 i whakahiatohia ma te taapiri i te iti o te dimethyldiethoxysilane ki roto i te monomethyltriethoxysilane matua.Kaore he waikawa pararopi e toe ana i roto i te kapia, na reira ka tino pumau te mahi rokiroki o te hua, a, karekau he sima i kitea i te tau i muri mai.Na te whakaurunga o te iti o nga rauemi mata ngoikore, he uaua, he reo, he ngawari nga hua sar-2, me te whānuitanga o nga tono.Ka taea te whakamahi whanui i roto i te karaihe, te kirihou, te whakarewa me etahi atu mea, ina koa mo te whakamarumaru o nga kirihou maamaa penei i te polycarbonate, polystyrene me te PVC, me te whakamarumaru-makuku me te whakamarumaru whakamarumaru o nga waahanga hiko, ka roa ka hangaia he nui- hanga tauine.
Mai i 1980 ki 1982, Qi hongqiu, Li Yan me Cui Zuoming i Chenguang Chemical Research Institute, a i 1981 ki 1983, Xu Zhihong me Xue Zhiqing i Shanghai wheketere kapia whakamahia methyltrichlorosilane rite te rauemi mata matua ki te whakarite silicone teitei pāmahana ātete mica whakapiringa.Ko nga tohu hua ko te mr-30 me te sar-8.I tua atu i te parenga teitei o te pāmahana, te whakamaarama hiko, te makuku-tohu, te wai-tohu me etahi atu taonga o nga hua organosilicon whanui, ko nga hua he nui te piri me nga waahi mura.Kei te nuinga whakamahia te reira mo te hanga teitei pāmahana ātete paura kapua papa whaea, hiko ngongo marara, teitei pāmahana ātete paura kapua poari whaea mo te tautoko, papa mica mo tahuri marara roto o te mīhini fehokotaki'anga hiko, me ētahi atu. hei paninga auahi-kore me te waikura, a ka taea hoki te whakamahi hei whakahiato whakahiato mokowhiti, he kapia whakahiao uku ranei i tito mai i te muka karaihe hiato laminate me te silica.He taonga nui a Haina i nga rawa paura mica, ka taea te whakawhanake ki te raupapa o nga hua o te papa mica mo te pāmahana teitei.
He tohungatanga a Jiangxi Huahao ki te hanga dimethyldiethoxysilane
Ko te Sar-8 me te sar-9 o te wheketere kapia o Shanghai e tango ana i a raatau ake tikanga tikanga: te hydrolyze me te waipiro organosilicon monomers me te aro me te polycondensate i te wa ano.Ko te Sar-8 me te sar-9 i mahia i te tau 1983, a kua tata ki te kotahi mano taranata te hua.Ko te rauemi mata matua o te hua ko te methyltrichlorosilane, na ahakoa ko te mr-30, sar-8, sar-9 ranei ka puta, ka taea te whakapai ake i te uara whakamahi o te methyltrichlorosilane.
Organosilicon hanga kirihou
I te tekau tau atu i 1960, i tino hiahia te ahumahi rererangi o Haina ki te ahua o te pewa kirihou moroiti moroiti ka taea te tu atu i te ngaohiko o naianei me te ngaohiko teitei mo te hanga huringa moroiti.Ko te Beijing Research Institute o te ahumahi matū kua pai te whakawhanake i te kapia silicone he mea whakamaarama tika mai i te methyltrichlorosilane ka hangaia ki te pewa pewa moko kirihou ki te whakakii asbestos, kua whakatauhia te hiahia ohorere o te umanga rererangi.I whakawhitia te rauemi ki te wheketere kapia Shanghai mo te hanga.Heoi, kei te hiahia tonu nga kaiwhakamahi ki tenei momo rauemi, no reira me tono awhina mai i te Chenguang Chemical Research Institute, i neke ki te Porowini o Sichuan.Hei whakatutuki i nga hiahia ohorere o nga kaiwhakamahi, Wu Shengquan et al.I whakamahia e te Institute te huarahi whakamaarama wai mai i te methyltriethoxysilane hei rauemi tiimata ki te whakarite i te kapia silicone mo te hanga kirihou me te pai o te mahi, kia pai ai te whakatutuki i nga hiahia ohorere o nga kaiwhakamahi.
Rauemi hiri kapia Silicone
I te mutunga o nga tau 1960, me te whanaketanga o te ahumahi hiko o Haina, he mea tika ki te whakamahi i nga rauemi hiri silicone me te pai o te whakamaarama hiko, te aukati teitei o te pāmahana, te makuku-tohu me te kore ngiha ki te kikii i nga diodes hiko nui me te iti, triodes, parenga, capacitors, iahiko whakauru me etahi atu taputapu hiko.I Haina, Zhang Xinghua, he Jigang, et al.O te Institute o te matū o te Hainamana Academy o Pūtaiao, me Zhang Jikai, Li Yansheng, et al.O Shanghai wheketere kapia i mahi wawe i roto i te whanaketanga o taua kapia.I whakawhanakehia e ratou nga momo momo hua hei whakakii i nga waahi o te kainga.
Ko te kapia Silicone kua whakarereketia te paninga
Ko te silicone whanui te nuinga o te polymethylsiloxane me te polyphenylsiloxane.Ko te hototahi o te kapia silicone kei roto te phenyl me te kapia waro he pai ake i tera o te kapia methyl silicone.Ka taea te whakapai ake i te parenga pāmahana me te aukati wai o nga paninga whanui ma te whakauru phenyl silicone ki roto.I roto i te ahumahi whakakikorua, ka taea te whakarite i te siloxane teitei kei roto te paninga ma te whakakotahi me te copolymerization o te phenyl kei roto te kapia silicone.I te timatanga o te 1960s, Tianjin peita wheketere me Shanghai wheketere kapia whakawhanakehia pai te paninga o silicone kapia waihanga whakarerekētia.He momo momo taonga pai kua whakawhanakehia, penei i te kapia epoxy kua whakarerekehia e te silicone me te pai o te wera me te piri.
