Silicone ikirahure resin hamwe nubushyuhe bwo hejuru burwanya silicone mika yifata．
Huo Changshun na Chen Rufeng bo mu kigo cy’ubushakashatsi cy’ubushakashatsi cya Chenguang, Minisiteri y’inganda z’imiti, nibindi barimo gutunganya ibirahuri bya silicone hamwe n’ubushyuhe bwo hejuru bwa mika mu Bushinwa.Mu mpera z'imyaka ya za 70, cts-103 silicone resin, bakunze kwita "silicone ikirahure", yatunganijwe neza na hydropolycondensation ya methyltriethoxysilane imbere ya catisale.Ibisigarira byakoreshwaga mu kuvura impapuro ziteye imbere, kurinda kurinda hejuru y’icyuma, no guhuza urupapuro rwa mika cyangwa ifu ya mika mu ntangiriro.Mu 1980, Sanhua, Xue Zhiqing na Li Yansheng, abakora ibisigazwa by’ibisigazwa muri Shanghai, bakoresheje resin ikomeye yo guhanahana ibintu nka catisale ya aside.Ibisigarira bya silicone bisobanutse kandi bidashobora kwambara bya sar-1 na sar-2 byahujwe no kongeramo akantu gato ka dimethyldiethoxysilane muri monomethyltriethoxysilane.Nta aside irike isigaye muri resin, bityo imikorere yo kubika ibicuruzwa irahagaze neza, kandi nta sima iboneka nyuma yumwaka.Bitewe no kumenyekanisha umubare muto wibikoresho fatizo bidahwitse, sar-2 ibicuruzwa birakomeye, biciriritse kandi byoroshye, hamwe nurwego runini rwa porogaramu.Irashobora gukoreshwa cyane mubirahuri, plastike, ibyuma nibindi bikoresho, cyane cyane mukurinda plastike ibonerana nka polyakarubone, polystirene na PVC, hamwe no gukingira ubushuhe hamwe no gukingira izitwikiriye ibikoresho bya elegitoronike, bizahita bikora binini- umusaruro mwinshi.
Kuva mu 1980 kugeza 1982, Qi hongqiu, Li Yan na Cui Zuoming bo mu kigo cy’ubushakashatsi cy’ubushakashatsi bw’imiti cya Chenguang, naho kuva 1981 kugeza 1983, Xu Zhihong na Xue Zhiqing bo mu ruganda rw’ibiti bya Shanghai bakoresheje methyltrichlorosilane nk'ibikoresho fatizo kugira ngo bategure mikorobe yangiza ubushyuhe bwa silika.Ibiciro byibicuruzwa ni mr-30 na sar-8.Usibye kurwanya ubushyuhe bwinshi, kubika amashanyarazi, kutagira amazi, kutagira amazi nibindi bintu byibicuruzwa rusange bya organosilicon, ibicuruzwa bifite kandi ibintu byinshi bifata neza kandi bikarinda umuriro.Ikoreshwa cyane cyane mugukora ubushyuhe bwokwirinda ifu yububiko bwibibaho, ibyuma bya elegitoronike, ubushyuhe bwo hejuru bwihanganira ifu yibicu byababyeyi kubufasha, ikibaho cya mika kugirango ihindurwe imbere yimashini isudira amashanyarazi, nibindi. nk'umwotsi utarimo umwotsi kandi urwanya ruswa, kandi urashobora no gukoreshwa nk'ibikoresho bidashobora gutwikwa cyangwa ceramic molding resin igizwe n'ibirahuri bya fibre compte laminate na silika.Ubushinwa bukungahaye ku ifu yifu ya mika, ishobora gutezwa imbere mubukonje bukabije bwo kwihanganira ibicuruzwa bya mika.
Jiangxi Huahao kabuhariwe mu gukora dimethyldiethoxysilane
Sar-8 na sar-9 byo muruganda rwa resin ya Shanghai bifata inzira zabo ziranga inzira: hydrolyze na alcoolis organosilicon monomers hamwe na concentrate na polycondensate icyarimwe.Sar-8 na sar-9 byashyizwe mu bikorwa mu 1983, umusaruro ugera kuri toni igihumbi.Ibikoresho nyamukuru byibicuruzwa ni methyltrichlorosilane, bityo haba mr-30 cyangwa sar-8 cyangwa sar-9 byakozwe, agaciro ka methyltrichlorosilane gashobora kunozwa cyane.
Organosilicon ibumba plastike
Mu myaka ya za 1960, inganda z’indege z’Ubushinwa zari zikeneye byihutirwa ubwoko bwa plasitike ya silicone irwanya arc ishobora kwihanganira ingufu zikomeye n’umuvuduko mwinshi wo gukora mikoro.Ikigo cy’ubushakashatsi cy’inganda cya Beijing cyateje imbere silicone resin ikozwe neza na methyltrichlorosilane kandi ikozwe muri plastiki idashobora kwihanganira ibishishwa byuzuza asibesitosi, byakemuye byihutirwa inganda z’indege.Ibikoresho byimuriwe mu ruganda rwa resin rwa Shanghai kugirango bikorwe.Nyamara, abakoresha baracyakeneye ibintu nkibi, bityo rero bagomba gusaba ubufasha mu kigo cy’ubushakashatsi bw’ubushakashatsi bwa Chenguang, cyimukiye mu Ntara ya Sichuan.Kugirango uhuze ibyifuzo byihutirwa byabakoresha, Wu Shengquan nabandi.Mu Kigo cyakoresheje inzira ya hydrolysis iva muri methyltriethoxysilane nkibikoresho byo gutangiza gutegura silicone resin yo kubumba plastike ikora neza, kugirango ikemure byihutirwa abakoresha.
Silicone resin yo gufunga ibikoresho
Mu mpera z'imyaka ya za 1960, hamwe n’iterambere ry’inganda za elegitoroniki y’Ubushinwa, birakenewe gukoresha ibikoresho bifunga kashe ya silicone hamwe n’amashanyarazi meza cyane, birwanya ubushyuhe bwinshi, bitarinda ubushyuhe kandi ntibitwikwa kugira ngo bipakire amashanyarazi manini kandi mato, triode, résistorants, capacator, imiyoboro ihuriweho hamwe nibindi bikoresho bya elegitoroniki.Mu Bushinwa, Zhang Xinghua, we Jigang, n'abandi.Ikigo cya chimie cyubumenyi bwubushinwa bwubushinwa, na Zhang Jikai, Li Yansheng, nabandi.Uruganda rwa resin rwa Shanghai rwagize uruhare mukwiteza imbere.Bateje imbere ibicuruzwa bitandukanye kugirango buzuze icyuho cyimbere mu gihugu.
Silicone resin yahinduwe
Silicone rusange igizwe ahanini na polymethylsiloxane na polifhenylsiloxane.Ubwuzuzanye bwa silicone resin irimo fenyl na resin organic nibyiza kuruta ibya methyl silicone resin.Kurwanya ubushyuhe hamwe n’amazi arwanya imyenda rusange birashobora kunozwa mugushiramo fenyl silicone.Mu nganda zitwikiriye, siloxane ikora cyane irimo coating irashobora gutegurwa muguhuza cyangwa gukoporora fenil irimo silicone resin.Nko mu myaka ya za 1960, uruganda rukora amarangi rwa Tianjin hamwe n’uruganda rwa resin rwa Shanghai rwateje imbere neza igipfundikizo cya silicone yahinduwe.Ibintu bitandukanye byiza byatejwe imbere, nka silicone yahinduwe epoxy resin hamwe nubushyuhe bwiza hamwe no gufatira hamwe.
