Silicone mafutaine zvinhu zvakawanda zvakakosha, senge yakaderera tembiricha viscosity coefficient, kuramba kune yakakwirira uye yakaderera tembiricha, oxidation kuramba, yakakwira flash point, yakaderera volatility, yakanaka insulation, kuderera kwepasi tension, hapana ngura kune simbi, isiri-chepfu, etc. Nekuda kweizvi. maitiro, mafuta esilicone ane mashandiro akanaka mune akawanda maapplication. Pakati pemafuta akasiyana-siyana esilicone, methyl silicone mafuta ndiyo inonyanya kushandiswa uye inonyanya kukosha mhando, inoteverwa nemethyl phenyl silicone mafuta. Yakasiyana-siyana inoshanda silicone oiri uye yakagadziridzwa silicone oiri inonyanya kushandiswa kune zvakakosha.
Hunhu: Husina ruvara, husina kunhuhwirira, husina chepfu, uye husina kuvhurika mvura.
Kushandiswa: Iine zvakasiyana-siyana viscosities. Iyo ine yakanyanya kupisa kupisa, kusamira kwemvura, kuvharwa kwemagetsi, uye kuderera kwepasi tension. Inowanzo shandiswa semafuta ekuzora epamusoro, mafuta ekuvhundutsa, mafuta ekudzivirira, defoamer, ajenti yekuburitsa, polishing agent, isolation agent, uye vacuum diffusion pombi mafuta; Lotion inogona kushandiswa kupukuta matayi emota, kukwenenzvera kwemidziyo, nezvimwewo Methyl silicone mafuta ndiyo inonyanya kushandiswa. Iyo yakapfava uye yakapfava tactile kupera inoshandiswa kune machira kupera mushure memulsification kana kugadziridzwa. Emulsified silicone oiri inowedzerwawo kune shampoo yemazuva ese ekuchengetedza zvigadzirwa kuvandudza mafuta ekuzora. Mukuwedzera, kune ethylsilicone mafuta, methylphenyl silicone mafuta, nitrile ine silicone oiri, polyether modified silicone mafuta (mvura-soluble silicone mafuta), nezvimwewo.
Iko kushandiswa kwemhando yesilicone oiri yakakura kwazvo. Haisi kungoshandiswa sechinhu chakakosha mundege, tekinoroji, uye madhipatimendi ehunyanzvi hwemauto, asiwo muzvikamu zvakasiyana zvehupfumi hwenyika. Chiyero chekushandisa chakawedzera kusvika ku: kuvaka, zvemagetsi nemagetsi, machira, mota, michina, matehwe nekugadzira mapepa, maindasitiri emakemikari uye akareruka, simbi nependi, mushonga uye kurapwa, zvichingodaro.
Zvikumbiro zvikuru zvesilicone mafutauye zvinobva pairi zvinobvisa firimu, mafuta ekuvhundutsa, dielectric mafuta, hydraulic mafuta, mafuta ekufambisa kupisa, diffusion pombi mafuta, defoamer, lubricant, hydrophobic agent, pendi additive, polishing agent, cosmetics uye zuva nezuva zvinhu zvemumba zvinowedzera, surfactant, particle uye fiber. mushonga wekurapa, silicone girisi, flocculant.
Zvakanakira:
(1) Iyo viscosity tembiricha kuita ndiyo yakanyanya kunaka pakati pemafuta ekuzora, ane diki viscosity shanduko pane yakakura tembiricha renji. Yayo yekuomesera poindi kazhinji isingasviki -50 ℃, uye mamwe anogona kusvika kusvika -70 ℃. Kana yakachengetwa kwenguva yakareba pakudziya kwakadzika, kutaridzika uye viscosity yemafuta zvinoramba zvisingachinji. Iwo mafuta egasi anofunga nezve yakakwirira, yakaderera, uye yakafara tembiricha mazinga.
(2) Yakanakisa thermal oxidation kugadzikana, senge thermal decomposition tembiricha>300 ℃, diki evaporation kurasikirwa (150 ℃, 30 mazuva, evaporation kurasikirwa chete 2%), oxidation bvunzo (200 ℃, 72 maawa), shanduko diki muviscosity uye acid. value.
(3) Yakanakisa kuvharwa kwemagetsi, vhoriyamu kuramba, nezvimwewo hazvishanduke mukati mechikamu chekushisa kwekamuri kusvika 130 ℃ (asi mafuta haagone kuve nemvura).
(4) Iyo isiri-chepfu, yakaderera furo, uye yakasimba anti foaming oiri inogona kushandiswa se defoamer.
(5) Yakanakisa shear kugadzikana, ine basa rekutora vibration uye kudzivirira vibration kupararira, inogona kushandiswa semvura inonyorovesa.
