Polyimide: Lebitso la Senyesemane Polymide (pi bakeng sa bokhutšoanyane)
Polyimide e le thepa e khethehileng ea boenjiniere, e sebelisoa haholo ka lifofane, likokoana-hloko tsa Nano, liquid khurtal, membrane le masimo a mang. Haufinyane tjena linaha li etsa lipatlisiso, li ntlafatsa le ho sebelisa polane e le e 'ngoe ea polaisi ea boenjiniere lekholong la bo21 la lilemo. Polyimide, ka lebaka la likarolo tsa eona tse ikhethang tse sebetsang le Syntmosis, ebang ke ka boitsebiso bo sebetsang, e tsejoang e le "bothata ba ho etsa bothata", le hore "ha ho na Polyimide e ke ke ea ba le mahlale a kajeno a likope tsa microlectics.
Polyimide ke sebopeho sa limolek'hule se nang le lihokelo tsa chanka tse thehiloeng ho 'nete tsa monko ) mekhahlelo e mene.
Polyimide P ha joale ke e 'ngoe ea mefuta e metle ea boenjiniere ea bongoana, mefuta e meng e ka ema mocheso o mongata oa nako ea ho teneha , malakabe a ho khutlela litekakong, ho tsitsa, ho tsitsipana ha thepa ea motlakase ho hotle, ho bopa sello se setle, oli e akaretsa, e na le lisente tse ntle, tse makatsang
Lipontšo tsa Lits'ebetso tsa elektroniki le tsa motlakase, indasteri ea elektroniki e hlahisang liboka tsa potoloho, mecha ea litlhare, matlo a futhumatsang mocheso, likhechana, likhetla le masimo a mang.
Hony Plas e Ikhethileng ea Hony Ho hlahiseng lithuso le meru ea marenene le ts'ebetsong ebe e bolila ho holisa lihlahisoa tse fapaneng tsa polyimide pi e fapaneng.
Ts'ebetso ea lihlahisoa tsa polyimide

Ka kakaretso, ha ho thata ho bona lebaka le etsang hore Polymimide e ka hlaha ho tloha bo-60 le tse 70, qetellong li-polymer tsa bohlokoa tsa thepa ea Polymer
Karolo ea likhoele tsa polyimide ka botlalo
Ka khase ea polyimide ke gakkete ea polasetiki e phahameng ea polasetiki e entsoeng ka thepa ea polyimide. Ganokete ena e phetha karolo ea bohlokoa ho hlahiseng indasteri, haholo-holo e bonts'itsoeng lintlheng tse latelang:
Taba ea pele, karolo ea ho nahana
Li-gaske tsa polyimide hangata li sebelisoa e le lisebelisoa tsa tsona tsa ho tiisa ka lebaka la ho hanyetsa e ntle le ho hanyetsa. Ka har'apa, li-comma, liplis le khokahano ea lisebelisoa tse ling, tšebeliso ea mabili a polyimide e ka thibela khase kapa ho tsoa moketeng, ho netefatsa ts'ebetso e tloaelehileng ea sistimi.
Ea bobeli, karolo ea ho tsoa
Ka lebaka la thepa e ntle ea ho hlahloba motlakase ea lisebelisoa tsa polyimide, kahoo libati tsa polyimide hangata li sebelisoa e le mabili a motlakase bakeng sa lisebelisoa tsa motlakase. E ka khetholla potoloho ena, thibela potoloho e khuts'oane, ka hona e ntlafatsa polokeho le botsitso ba lisebelisoa tsa motlakase.
Ea boraro, ea buffer
Ka lisebelisoa tsa mochini, likarolo tse ngata tse sebetsang li tla hlahisa vibration le tšusumetso. Kabelo ea Polyimide ka lebaka la ho hleka, 'me u rorise sebui lipakeng tsa likarolo tsena, fokotsa lerata, a u jella bophelo ba lisebelisoa.
Ea bone ea lik'hemik'hale ea lik'hemik'hale
Lisebelisoa tsa pondemide li na le litsie tse ntle tsa lik'hemik'hale, li ka hanela li-asiti tse ngata, alkalis, solvent ea manyolo le lintho tse ling tsa lik'hemik'hale. Ka hona, indasteri ea lik'hemik'hale le mekhabiso ea lik'hemik'hale, mabitla a polyimide e sebelisoa haholo lipeileng tse fapaneng, li-reckingls tse fapaneng le maemong a mang le ho tiisoa.
Ka kakaretso, polemimide polyimide e bapala karolo e ngata ea bohlokoa ea tlhahiso ea indasteri. Ho hanyetsa mocheso oa sona o motle oa mocheso, ho hana ho hanyetsa, ho senya mefuta le lisebelisoa tsa motlakase, le lisebelisoa tsa motlakase. Ebang ebang ke ho qoqa, insulation, ho hloka bosula kapa ho hanyetsa ho hanyetsa ho hanyetsa khang kapa lik'hemik'hale, mabili a polyimide a bontšitse ts'ebetso e ntle haholo.
