Silicone girazi resin uye yakakwirira tembiricha inodzivirira silicone mica adhesive.
Huo Changshun naChen Rufeng vanobva kuChenguang Chemical Research Institute, Ministry of chemical industry, etc. vari kugadzira silicone glass resin uye high tembiricha mica adhesive muChina.Mukupera kwema1970, cts-103 silicone resin, inowanzozivikanwa se "silicone girazi resin", yakabudirira kugadzirwa nehydropolycondensation yemethyltriethoxysilane pamberi pe acid catalyst.Iyo resin yakashandiswa mukurapa kwebepa repamusoro, kudzivirira kwekuvhara kwesimbi pamusoro, uye kusungirirwa kwemica sheet kana mica poda padanho rekutanga.Muna 1980, Sanhua, Xue Zhiqing naLi Yansheng, vagadziri ve resin muShanghai, zvakateerana, vakashandisa yakasimba cation exchange resin senge yechinguva acid inokonzeresa.Iyo yakajeka uye inopfeka-inodzivirira silicone resins ye sar-1 uye sar-2 yakagadzirwa nekuwedzera shoma shoma ye dimethyldiethoxysilane muhombe monomethyltriethoxysilane.Iko hakuna yakasara inorganic acid muresin, saka kuchengetedza kwechigadzirwa kwakanyatso kugadzikana, uye hapana simende inowanikwa gore gare gare.Nekuda kwekuunzwa kwehushoma hwezvinhu difunctional mbishi, sar-2 zvigadzirwa zvakaoma, zvepakati uye zvakapfava, zvine huwandu hwakawanda hwekushandisa.Inogona kushandiswa zvakanyanya mugirazi, mapurasitiki, simbi uye zvimwe zvinhu, kunyanya kudzivirira mapurasitiki akajeka akadai se polycarbonate, polystyrene uye PVC, uye nekunyorova-uchapupu uye kuvhara kwekudzivirira kwekudzivirira kwezvikamu zvemagetsi, izvo zvichakurumidza kuumba hombe- kugadzirwa kwechiyero.
Kubva 1980 kusvika 1982, Qi hongqiu, Li Yan naCui Zuoming kubva kuChenguang Chemical Research Institute, uye kubva 1981 kusvika 1983, Xu Zhihong naXue Zhiqing vanobva kuShanghai resin fekitori vakashandisa methyltrichlorosilane sechinhu chikuru chekushandisa kugadzira silicone yakakwira tembiricha inodzivirira mica adhesive.Iwo chigadzirwa mamakisi ari mr-30 uye sar-8 zvakateerana.Kuwedzera kune yakanyanya kupisa tembiricha kuramba, magetsi ekudzivirira, hunyoro-uchapupu, mvura-chiratidzo uye zvimwe zvimiro zveyakajairwa organosilicon zvigadzirwa, zvigadzirwa zvakare zvine yakakwirira yekunamatira uye inodzoreredza moto.Inonyanya kushandiswa kugadzira tembiricha inodzivirira hupfu gore mama bhodhi, yemagetsi chubhu insulation, tembiricha inodzivirira hupfu gore mama bhodhi kuti itsigire, mica board yekushandura mukati insulation yemagetsi welding muchina, nezvimwe zvakasiyana-siyana zvinodzivirira kupisa pigment zvinogona kuwedzerwa. se-isina utsi uye anti-corrosion coatings, uye inogona zvakare kushandiswa seisingabatike inoumbwa inoumba composite kana ceramic molding resin inoumbwa negirazi fiber composite laminate uye silica.China yakapfuma mumica poda zviwanikwa, izvo zvinogona kuvandudzwa kuita nhevedzano yeakakwira tembiricha inodzivirira insulating mica board zvigadzirwa.
Jiangxi Huahao anoshanda mukugadzira dimethyldiethoxysilane
Sar-8 uye sar-9 yeShanghai resin fekitori vanotora yavo yega maitiro maitiro: hydrolyze uye alcoholysis organosilicon monomers uye concentrate uye polycondensate panguva imwe chete.Sar-8 uye sar-9 zvakaiswa mukugadzirwa muna 1983, uye zvakabuda zvasvika angangoita chiuru matani.Iyo huru yezvigadzirwa zvechigadzirwa ndeye methyltrichlorosilane, saka kunyangwe mr-30 kana sar-8 kana sar-9 inogadzirwa, kukosha kwekushandisa kwemethyltrichlorosilane kunogona kuvandudzwa zvakanyanya.
Organosilicon kuumba mapurasitiki
Mumakore ekuma1960, indasitiri yezvendege yeChina yaida nekuchimbidza rudzi rwearc inodzivirira silicone mold plastiki iyo inogona kumira yakasimba ikozvino uye yakakwirira voltage yekugadzira diki switch.Beijing Research Institute yeindasitiri yemakemikari yakabudirira kugadzira silicone resin iyo yakanyatso hydrolyzed kubva kumethyltrichlorosilane uye yakagadzirwa kuita arc inodzivirira mold plastiki ine asbestos filler, iyo yakagadzirisa kudiwa kwekukurumidzira kweindasitiri yendege.Izvo zvinhu zvakaendeswa kuShanghai resin fekitori yekugadzirwa.Nekudaro, vashandisi vachiri kuda rudzi urwu rwezvinhu, saka vanofanirwa kukumbira rubatsiro kubva kuChenguang Chemical Research Institute, iyo yakatamira kuSichuan Province.Kuti usangane nezvido zvekukurumidzira zvevashandisi, Wu Shengquan et al.YeInstitute yakashandisa iyo hydrolysis condensation nzira kubva kumethyltriethoxysilane sechinhu chekutanga kugadzirira silicone resin yekuumba mapurasitiki nekuita kunogutsa, kuitira kugadzirisa nekukurumidza zvinodiwa nevashandisi.
Silicone resin sealing material
Mukupera kwema1960s, nekuvandudzwa kweindasitiri yemagetsi yeChina, zvakakosha kushandisa silicone yekuisa chisimbiso zvinhu zvine simba rekudzivirira magetsi, kupisa kwakanyanya, kunyorova uye kusapisa kurongedza madhiodhi makuru uye madiki emagetsi, matatu, resistors, capacitors, masekete akabatanidzwa uye zvimwe zvigadzirwa zvemagetsi.MuChina, Zhang Xinghua, iye Jigang, et al.YeInstitute of chemistry yeChinese Academy yeSainzi, uye Zhang Jikai, Li Yansheng, et al.YeShanghai resin fekitori yakatanga kuita mukugadzirwa kwemarezeni akadaro.Vakagadzira zvigadzirwa zvakasiyana-siyana kuti zvizadze mukaha wepamba.
Silicone resin yakagadziridzwa coating
Iyo general silicone inonyanya kuumbwa ne polymethylsiloxane uye polyphenylsiloxane.Iko kuwirirana kwesilicone resin ine phenyl uye organic resin iri nani pane iyo yemethyl silicone resin.Kuramba tembiricha uye kushorwa kwemvura kwejasi rejasi kunogona kuvandudzwa nekuunza phenyl silicone mavari.Muindasitiri yekuputira, yakakwirira-inoshanda siloxane ine coating inogona kugadzirwa nekusanganisa kana copolymerization yephenyl ine silicone resin.Kare kuma1960s, fekitori yependi yeTianjin uye fekitori yeShanghai resin yakabudirira kugadzira kuvharwa kwesilicone yakagadziridzwa synthetic resin.Zvinhu zvakasiyana-siyana zvakanaka zvakagadzirwa, zvakadai sesilicone yakagadziridzwa epoxy resin ine yakanaka yekudzivirira kupisa uye kunamatira.
