Ha ho tluoa tabeng ea lisebelisoa tse tsoetseng pele, ha ho pelaelo hore silicone ke taba e chesang. Silicone ke mofuta oa thepa ea polymer e nang le silicon, carbon, hydrogen le oksijene. E fapane haholo le thepa ea silicon ea inorganic mme e bonts'a ts'ebetso e ntle haholo mafapheng a mangata. Ha re hlahlobeng ka botebo litšobotsi, mokhoa oa ho sibolla le tataiso ea tšebeliso ea silicone.
Phapang lipakeng tsa silicone le silicon ea inorganic:
Ntlha ea pele, ho na le phapang e totobetseng ea sebopeho sa lik'hemik'hale pakeng tsa silicone le silicon ea inorganic. Silicone ke lintho tse entsoeng ka polymer tse entsoeng ka silicon le carbon, hydrogen, oxygen le likarolo tse ling, ha silicon ea inorganic e bua haholo ka metsoako ea tlhaho e entsoeng ke silicon le oksijene, joalo ka silicon dioxide (SiO2). Sebopeho sa silicone se entsoeng ka carbon se se fa elasticity le polasetiki, e leng se etsang hore e be bonolo haholoanyane ho sebelisoa. Ka lebaka la litšobotsi tsa sebopeho sa limolek'hule tsa silicone, ke hore, matla a bond ea Si-O bond (444J / mol) a phahame ho feta a CC bond (339J / mol), thepa ea silicone e na le mocheso o phahameng ho feta metsoako e akaretsang ea polymer.
Ho fumanoa ha silicone:
Ho sibolloa ha silicone ho ka saloa morao ho tloha qalong ea lekholo la bo20 la lilemo. Mehleng ea pele, bo-rasaense ba ile ba atleha ho kopanya silicone ka ho hlahisa lihlopha tsa manyolo ka har'a metsoako ea silicon. Tšibollo ena e ile ea bula mehla e mecha ea thepa ea silicone 'me ea rala motheo oa ts'ebeliso ea eona e pharaletseng indastering le saenseng. Tšimoloho le ntlafatso ea silicone e hatetse pele haholo lilemong tse mashome a seng makae tse fetileng, e khothalletsang boqapi bo tsoelang pele le nts'etsopele ea thepa ena.
Li-silicone tse tloaelehileng:
Li-silicones ke sehlopha sa metsoako ea polymer e fumanehang haholo tlhahong le moetsong oa maiketsetso, ho kenyeletsoa mefuta le meaho e fapaneng. Mona ke mehlala e meng ea li-silicone tse tloaelehileng:
Polydimethylsiloxane (PDMS): PDMS ke silicone elastomer e tloaelehileng, e atisang ho fumanoa ka rabara ea silicone. E na le phetoho e babatsehang le botsitso ba mocheso o phahameng, 'me e sebelisoa haholo ha ho etsoa lihlahisoa tsa rabara, lisebelisoa tsa bongaka, lubricant, joalo-joalo.
Oli ea Silicone: Oli ea silicone ke motsoako oa silicone o nang le mohala o nang le tsitsipano e tlase le ho hanyetsa mocheso o phahameng. Hangata e sebelisoa ho mafura, lihlahisoa tsa tlhokomelo ea letlalo, lisebelisoa tsa bongaka le likarolo tse ling.
Resin ea Silicone: Resin ea silicone ke thepa ea polymer e entsoeng ka lihlopha tsa silicic acid tse nang le matla a ho hanyetsa mocheso le thepa ea ho kenya motlakase. E sebelisoa haholo ho lira, likhomaretsi, liphutheloana tsa elektroniki, joalo-joalo.
Rabara ea Silicone: Rabara ea silicone ke thepa ea silicone e kang rabara e hanyetsanang le mocheso o phahameng, ho hanyetsa boemo ba leholimo, ho kenya motlakase le thepa e meng. E sebelisoa haholo ka mehele ea ho tiisa, li-sleeve tsa tšireletso tsa cable le masimo a mang.
Mehlala ena e bontša mefuta-futa ea li-silicone. Ba bapala karolo ea bohlokoa mafapheng a fapaneng 'me ba na le mefuta e mengata ea likopo ho tloha indastering ho ea bophelong ba letsatsi le letsatsi. Sena se boetse se bonahatsa litšobotsi tse fapa-fapaneng tsa li-silicone e le lisebelisoa tse phahameng tsa ts'ebetso.
Melemo ea Ts'ebetso
Ha ho bapisoa le metsoako e tloaelehileng ea carbon chain, organosiloxane (Polydimethylsiloxane, PDMS) e na le melemo e ikhethang ea ts'ebetso, e leng se etsang hore e bontše ts'ebetso e babatsehang lits'ebetsong tse ngata. Tse latelang ke melemo e meng ea ts'ebetso ea organosiloxane holim'a metsoako e tloaelehileng ea ketane ea carbon:
Ho hanyetsa mocheso o phahameng: Organosiloxane e na le khanyetso e ntle ea mocheso o phahameng. Sebopeho sa li-silicon-oxygen bonds se etsa hore li-organosiloxanes li tsitsitse mocheso o phahameng 'me li se ke tsa senyeha habonolo, e leng se fanang ka melemo bakeng sa ts'ebeliso ea eona libakeng tse phahameng tsa mocheso. Ka lehlakoreng le leng, metsoako e mengata e tloaelehileng ea ketane ea carbon e ka 'na ea bola kapa ea lahleheloa ke ts'ebetso ka mocheso o phahameng.
Khatello e tlase ea holim'a metsi: Organosiloxane e bonts'a tsitsipano e tlase, e etsang hore e be le mongobo o motle le lubricity. Thepa ena e etsa oli ea silicone (mofuta oa organosiloxane) e sebelisoang haholo ho litlolo, lihlahisoa tsa tlhokomelo ea letlalo le lisebelisoa tsa bongaka.
Ho feto-fetoha ha maemo le elasticity: Sebopeho sa limolek'hule tsa organosiloxane se e fa maemo a matle le elasticity, e etsa hore e be khetho e nepahetseng bakeng sa ho lokisa lisebelisoa tsa rabara le rekere. Sena se etsa hore rabara ea silicone e sebetse hantle ha ho lokisoa mehele ea ho tiisa, likarolo tsa elastic, joalo-joalo.
Ho kenya motlakase: Organosiloxane e bonts'a thepa e ntle ea ho kenya motlakase, e etsang hore e sebelisoe haholo lefapheng la elektroniki. Silicone resin (mofuta oa siloxane) hangata e sebelisoa linthong tsa ho paka tsa elektroniki ho fana ka mokelikeli oa motlakase le ho sireletsa likarolo tsa elektroniki.
Biocompatibility: Organosiloxane e na le tumellano e phahameng le lisele tsa likokoana-hloko 'me ka hona e sebelisoa haholo lisebelisoa tsa bongaka le masimo a biomedical. Ka mohlala, rabara ea silicone e atisa ho sebelisoa ho lokisetsa silicone ea bongaka bakeng sa litho tsa maiketsetso, li-catheters tsa bongaka, joalo-joalo.
Botsitso ba lik'hemik'hale: Li-Organosiloxanes li bonts'a botsitso ba lik'hemik'hale tse phahameng le khanyetso e ntle ea kutu ho lik'hemik'hale tse ngata. Sena se lumella ts'ebeliso ea eona indastering ea lik'hemik'hale hore e atolosoe, joalo ka ho lokisa litanka tsa lik'hemik'hale, liphaephe le lisebelisoa tsa ho tiisa.
Ka kakaretso, li-organosiloxanes li na le thepa e fapaneng ho feta metsoako e tloaelehileng ea ketane ea carbon, e ba nolofalletsang ho phetha karolo ea bohlokoa likarolong tse ngata tse kang ho tlotsa, ho tiisa, bongaka le lisebelisoa tsa elektronike.
