Chii chinonzi Methyl Silicone Oiri?
Kazhinji, methylsilicone mafutahaina ruvara, haina kunaka, haina muchetura uye isina kuvhurika mvura.Haina kunyungudika mumvura, methanol kana ethylene glycol.Inogona kusanganiswa nebenzene, dimethyl ether, carbon tetrachloride kana parafini.Inonyungudika zvishoma muacetone, dioxan, ethanol uye butanol.Kana iri methyl silicone oiri, nekuti iyo intermolecular simba idiki, iyo molecular chain is spiral, uye organic mapoka anogona kutenderedzwa zvakasununguka, ine yakanakisa hunhu hwekuparadzira kuita, lubricity, yakakwirira uye yakaderera tembiricha kuramba, mamiriro ekunze, kuramba kwemwaranzi, high flash point, low surface tension uye physiological inertia, etc. Inoshandiswa zvakanyanya mumaindasitiri ezuva nezuva.makemikari, michina, magetsi,textile, kupfekedza, mushonga uye chikafu, nezvimwe.
Tiye Hunhu hweMethyl Silicone Mafuta
Methyl silicone oiri ine yakawanda yakakosha kuita.
■ Kupisa kwakanaka kwekudzivirira
Mune silicone oiri molecular, iyo huru cheni inoumbwa ne -Si-O-Si-, iyo ine yakafanana chimiro ine inorganic polymer uye ine yakakwirira bond simba.Saka ine kuita kwakanakisa kwekudzivirira kupisa.
∎ Kuramba kwakanaka kweoxidation uye kusagadzikana kwemamiriro ekunze
■ Kushanda zvakanaka kwemagetsi ekudzivirira
Silicone oiri ine yakanakisa dielectric zvivakwa.Nekuchinja kwekushisa uye nhamba yekutenderera, maitiro ayo emagetsi anochinja zvishoma.Dielectric nguva dzose inoderera sezvo tembiricha inowedzera, asi shanduko idiki kwazvo.Simba remafuta esilicone rakaderera uye rinowedzera nekukwira kwekushisa, asi hapana mitemo yekuwanda.Vhoriyamu resistivity inoderera nekuwedzera tembiricha.
■ Yakanakisa hydrophobicity
Kunyangwe iyo cheni huru yesilicone oiri inoumbwa ne polar bond, Si-O, iyo isiri-polar alkyl mapoka ari padivi cheni anotariswa kunze kudzivirira mamorekuru emvura kupinda mukati uye kutamba hydrophobic basa.The interfacial tension pakati pesilicone mafuta nemvura inenge 42 dynes/cm.Kana ichipararira pamusoro pegirazi, nekuda kwekudzoreredza kwayo mvura, mafuta esilicone anogona kugadzira kona yekubata inosvika 103 °, inofananidzwa neparafini wax.
■ Diki viscosity-tembiricha coefficient
Iyo viscosity yesilicone oiri yakaderera uye inochinja zvishoma nekupisa.Iyo ine hukama neyekutenderera chimiro chesilicone oiri mamorekuru.Silicone mafuta ndiyo ine yakanakisa viscosity-tembiricha hunhu pakati pemarudzi ese emafuta ekuzora.Hunhu uhu hunoita hunzwisisiro kumudziyo wekunyorovesa.
■ Kunyanya kupikisa kudzvinyirira
Nekuda kweiyo spiral chimiro uye yakakura intermolecular chinhambwe, silicone oiri ine yakakwira compressibility kuramba.Uchishandisa iyi hunhu hwesilicone mafuta, inogona kushandiswa sechitubu chemvura.Kuenzaniswa ne mechanical spring, vhoriyamu inogona kuderedzwa zvikuru.
■ Kudzikama kwepasi
Kudzika kwepasi tension ndiyo hunhu hwesilicone oiri.Kuderera kwepasi kunoratidza kushanda kwepamusoro.Nekudaro, oiri yesilicone ine yakanakisa defoaming uye antifoaming kuita, yekuzviparadzanisa nevamwe nezvimwe zvinhu uye kuita kwekuzora.
∎ Isiri-chepfu, isina-kushanduka uye inertia yemuviri
Kubva pamaonero ehupenyu, siloxane polymer ndeimwe yemakomisheni mashoma anoshanda anozivikanwa.Dimethyl silicone oiri inert kune zvipenyu uye haina kurambwa kuita nemhuka.Saka yakashandiswa zvakanyanya mudhipatimendi rekuvhiya uye dhipatimendi remishonga yemukati, mushonga, chikafu uye zvizorwa, nezvimwe.
■ Mafuta akanaka
Mafuta eSilicone ane akawanda emhando yepamusoro semafuta ekuzora, senge yakakwira flash point, yakaderera kutonhora, kugadzikana kwekupisa, kudiki kudiki kushanduka nekupisa, kusaora kwesimbi uye kusakanganisa kwakaipa parabha, purasitiki, pendi uye organic pendi firimu, pasi pasi. kukakavara, nyore kupararira pamusoro pesimbi uye zvichingodaro.Kuti uvandudze simbi kune simbi lubricity yesilicone oiri, lubricating additives inogona kusanganiswa nesilicone oiri inogona kuwedzerwa.Iyo yekuzora zvimiro zvesilicone oiri inogona kuvandudzwa zvakanyanya nekuunza chlorophenyl boka mune siloxan cheni kana kutsiva dimethyl boka ne trifluoropropyl methyl boka.
