Ho hanyetsa Mocheso: Lishiti tsa Silicone: Li tšoarella ka mokhoa o ikhethang. Lipampiri tsena li boloka botsitso ba nako e telele-ho tloha ho{4}}60 degrees ho isa ho +230℃, ka nako e khuts'oane-ea mamello ho fihlela ho 250 degrees kapa 300 degrees . Sena se etsa hore li tšoanelehe bakeng sa maemo a phahameng a-mocheso a kang lionto, literei tsa ho baka, lijana tse koetsoeng ka mocheso, litsiki tsa mocheso le lisebelisoa tsa elektroniki. Rubber Sheets: E lekanyelitsoe ts'ebetsong. Lithempereichara tse khethehileng li itšetlehile ka mofuta oa rabara: Rabara ea Tlhaho: -50 degrees ho isa ho +70℃(e theola mocheso o phahameng 'me e be brittle mocheso o tlase). Styrene Butadiene Rubber (SBR): -40℃ho isa ho +100℃. Nitrile Rubber (NBR): -30℃ho isa ho +120℃(e ipabola ho hanyetsa oli). Ethylene Propylene Diene Monomer (EPDM) Rubber: -50℃ho +150℃(boemo bo botle ba leholimo le ozone resistance). Fluororubber: -20℃ho +200℃kapa ho feta (mocheso o ikhethang le k'hemik'hale e hanyetsanang le lik'hemik'hale, leha e le theko e boima).
Botsitso ba Lik'hemik'hale le Ho Hanyetsa Botsofali:Silicone Sheets: E bontša khanyetso e ikhethang ho oksijene, ozone le mahlaseli a ultraviolet. Li bontša khanyetso e tsotehang ea botsofali, li boloka ho tenyetseha ntle le ho thatafala, ho phunyeha, kapa ho lahleheloa ke elasticity esita le ka mor'a ho sebelisoa nako e telele, hangata li fana ka bophelo bo bolelele ba tšebeletso. Maqephe ana a bontša mamello e ntle ho lihlapolli tsa polar (joaloka joala, li-ketone, le li-acids tse itseng), empa a bontša ho hanyetsa ha -litlhapi tse se nang polar (mohlala, li-aliphatic hydrocarbons, aromatics hydrocarbons, petroleum{{5}lioli tse thehiloeng ho oli) le li-acid tse matla/alkali, tse ka bakang ho ruruha kapa ho senyeha. Rubber Sheets: Ho hanyetsa botsofali ho fapana ho ea ka mofuta oa thepa. Rabara ea tlhaho le rabara ea styrene{8}}butadiene (SBR) e na le kutloelo-bohloko ho ozone le mahlaseli a UV, a tloaetseng ho peperana le ho tsofala. EPDM le fluororubber li bonts'a khanyetso e phahameng ea boemo ba leholimo. Liphapang Tse Hloahloa Tsa Khanyetso ea Lik'hemik'hale: Rabara ea Nitrile: Ha oli{11}}e hanana le oli ({12}lioli tse thehiloeng ho oli{12}, aliphatic hydrocarbons). Fluororubber: Ho hanyetsa lik'hemik'hale tse ikhethang (tse hanyetsanang le oli, acid, alkalis, solvents). Rubber ea Tlhaho: E hanana le li-acids tse fokolang / alkalis empa eseng oli / solvents. EPDM: E hanana le metsi, mouoane, li-acid tse fokolang/alkalis, le lihlapolli tsa polar, empa e seng oli kapa metsoako ea hydrocarbon.
Mabapi le khanyetso ea lik'hemik'hale, mefuta ka bobeli e na le tsepamiso e fapaneng 'me e lokela ho khethoa ho latela mecha ea litaba e itseng.
Lintho tsa 'mele le tsa mochini: Lipampiri tsa rabara tsa silicone: Matla a mochine (matla le matla a ho taboha) hangata a tlase ho feta liraba tse ngata. Ha li ntse li hlahisa elasticity e ntle, ts'ebetso ea tsona e sa feleng ea compression deformation e kanna ea se ts'oane le liraba tse itseng tse phahameng (haholo-holo tlas'a khatello ea nako e telele{2}}ea mocheso o phahameng). Li bonts'a botsitso bo botle ba ho hlaphoheloa 'me li boloka ho feto-fetoha ha maemo ha mocheso o tlase. Lishiti tsa rabara: Ka tloaelo li bonts'a matla a holimo a mochini (haholo-holo a tsitsitse le a tabohang). Ts'ebetso e sa feleng ea compression deformation e fapana ho ea ka mofuta le sebopeho, ka liraba tse ling (mohlala, EPDM) li sebetsa hantle. Boiketlo ba ho hlaphoheloa hangata boa khotsofatsa. Thempereichara-ho ipapisitse le mofuta oa thepa (mohlala, rabara ea tlhaho e sebetsa betere ha mocheso o le tlase ha rabara ea nitrile e thatafala maemong a batang).
Insulation ea Motlakase:Li-Silicone Sheets: E na le thepa e babatsehang ea ho kenya motlakase e nang le matla a phahameng a ho hanyetsa le matla a dielectric, ho boloka botsitso ho pholletsa le mefuta e mengata ea mocheso le maqhubu. E sebelisoa haholo lits'ebetsong tsa elektroniki le tsa motlakase. Li-Sheets tsa Rubber: Ka kakaretso li bonts'a mokelikeli o motle oa motlakase (haholo-holo EPDM), leha e ka 'na ea se ke ea lumellana le bohloeki le botsitso ba silicone. Li-rubber tse ling (mohlala, li-rubber tse nang le carbon black) li ka etsoa bakeng sa conductivity kapa thepa ea antistatic. Qetello: Silicone e bonts'a melemo ea maemo a holimo-mosebetsing oa ho koala motlakase o phahameng (haholo-holo-mocheso o phahameng le{8}}tikolohong ea maqhubu a holimo). Biocompatibility le -Nature e Se nang Chefo: Lishiti tsa Silicone: E bonts'a ho se sebetse hantle ha 'mele le ho lumellana ho ikhethang ha lintho. E entsoe ha bonolo hore e be lihlahisoa tse tsamaellanang le litekanyetso tsa Food Grade (FDA, LFGB) le Medical Grade (USP Class VI). Ha e na monko ebile ha e na baktheria{13}}. Li-Sheets tsa Rubber: Li fapane haholo ka biocompatibility. Rabara ea tlhaho e ka 'na ea baka ho kula. Ho fumana setifikeiti sa Kereiti ea Lijo kapa Kereiti ea Bongaka, ho hlokahala khetho e tiileng ea lisebelisoa le li-additives (lisebelisuoa tse senyang, li-accelerator, li-anti{17}}botsofali, joalo-joalo). Li-additives tsena li na le likotsi tse phahameng tsa ho falla ha li bapisoa le silicone, tse ka ntšang monko oa rabara.
Ho kenella ha khase: Lipampiri tsa Silicone: Lisebelisoa tsena li bonts'a ho kenella ho hoholo ha likhase (mohlala, moea) le mouoane oa metsi. Leha thepa ena e le molemo bakeng sa lits'ebetso tse itseng (mohlala, liphaephe tse phefumolohang, lisebelisoa tsa membrane ea ho hema), e kanna ea ipaka e le mofoko ho ts'ebetso ea ho tiisa. Lishiti tsa rabara: Ka kakaretso li na le ho kenella ha khase e tlase, haholo rabara ea butyl, e sebetsang e le thepa e ntle e thibelang moea.
Qetello: Rabara ka kakaretso e molemo ho etsa litiiso tse sa keneleng moea le tse sa keneleng metsi. Litšobotsi tsa sefahleho: Letlapa la silicone: Bokaholimo bo na le hydrophobic (ho hloea metsi), ha bo khomarele habonolo lintho tse ngata, ho bonolo ho li hloekisa. Letlapa la rabara: Litšobotsi tsa bokaholimo li fapana ho latela mofuta le foromo, tse ling li ka khomarela.
Litšenyehelo: Letlapa la Silicone: le batla le tura. Litsenyehelo tsa lisebelisoa tse tala le litšenyehelo tsa tlhahiso hangata li phahame ho feta rabara e tloaelehileng. Rubber plate: mefuta e mengata ea litšenyehelo. Rabara ea tlhaho, SBR, NBR le litšenyehelo tse ling tse sebelisoang hangata li tlase. Litšenyehelo tsa rabara tse khethehileng (tse kang fluororubber, silicone rabara ka boeona) li phahame.
Khetho ea ho qetela e lokela ho khethoa ho latela ts'ebeliso-litlhoko tse khethehileng tse kenyeletsang sebaka sa mocheso oa ts'ebetso, ho kopana le lisebelisoa tsa lik'hemik'hale, lisebelisoa tsa motlakase, ho lumellana ha lijo-le boemo ba bongaka{2}}, litlhoko tsa ho thibela moea, le likhaello tsa tekanyetso.
