Ha ho tluoa ho rahatsa le ho hira lihlopha le likarolo tse hlabang, khetho ea lintho tse bonahalang e bohlokoa. Li-polymers tse phahameng li fana ka moelelo o matla oa thepa ea setso, e le meputso, e leng melemo le melemo ea boima le ho boloka 'mele. Sengoliloeng sena se hlahloba lefatše la lihloli tsa matla a maholo, thepa ea bona le hore na ba ka phahamisa ts'ebetso ea merero ea hao joang.
Matla a utloisisang polymers
Matla a bua ka bokhoni ba polymer ba ho hanela bo-rahistori kapa ho robeha tlas'a khatello ea maikutlo. Lintlha tse 'maloa li susumetsa matla a polymer:
- Boima ba Molecular:Li-polymer tse phahameng tsa moleng tsa lisele tsa namacular ka kakaretso li bontša matla a maholo ka lebaka la ho eketseha ha likeleli tsa ketane le litsi tse tšoanang.
- Crystallility:Tekanyo ea kristasta, kapa tokisetso ea liketane tsa polymer ka sebopeho se laetsoeng, se ka ama matla haholo. Polymer polymer o tloaetse ho ba matla.
- FlockLiking:Ho hlahisa li-crosslinki pakeng tsa li-plymer Chains li theha marang-rang a thata, a ntlafatsa matla le botsitso.
Mefuta ea Polymers e phahameng ea matla
Ho na le mefuta e mengata ea bakopitsi ba nang le matla a matla ho litlhoko tsa sephooneng. Mona ke tse ling tsa mefuta e hlophisitsoeng haholo:
- Aromatic (li-aramids, polyimides):Polymers tsena li na le likarolo tse khethehileng tsa matla le boima ba boima ba boima ba boima le ho rekoa ka lik'hemik'hale tse ntle tsa lik'hemik'hale. Ba fumana litlhophiso libakeng tse batlang joalo ka Aerospace e qapiloeng joalo ka Aerospace e qapiloeng, ts'ireletso ea bokhoba le masela a sebetsang a phahameng.
- Phahamisang-ts'ebetso Polyethylene (HPPP):E tsejoa ka tšusumetso ea eona ea tšusumetso le tšusumetso ea eona ea tšusumetso ea tšusumetso ea tšusumetso ea tšusumetso ea tšusumetso ea tšusumetso ea tšusumetso ea tšusumetso le eona hangata e sebelisoa ka liropo, likhoele bakeng sa ts'ireletso ea boloro le li-groaves.
- Polycarbonate (PC):Polymer ena e fetoha matla a leka-lekaneng, e hlakileng ebile e hanyetsana ebile e hanyetse. E sebelisoa haholo lisebelisoa tsa polokeho, lifemente tse thibelang bullet, le likarolo tsa sebopeho.
- Acrylonitrile Buydiene Styrene (ABS):Ho tsejoa ka matla a eona a matle, matla a eona le boiketlo ba ts'ebetso, ABS ke khetho e tsebahalang ea likopo tse fapaneng joalo ka likaroloana tsa likoloi.
- Ultra-High Molecular boima ba polyethylene (UHMWPE):Ho ithorisa ka mokhoa o ikhethileng o ikhethileng le likhohlano tse tlase, uhmwpe li fumana likopo tsa manonyeletso, litsing tsa maiketsetso le li-pads tsa maiketsetso.
Melemo ea ho Sebelisa Polymers e phahameng e matla
Li-polymers tse phahameng li fana ka melemo e mengata ho theosa le lisebelisoa tsa setso, li li etsa hore li lokele likopo tse fapaneng:
- Bobebe:Ha ho bapisoa le li-folls, lithothokiso tse phahameng li fana ka chelete ea bohlokoa ea boima, e leng ea bohlokoa likopo tse kang aerospace le lipalangoang.
- Ho Boloka:Li-polymers tsena li bontša khanyetso e ikhethang ho roala, ho laola lik'hemik'hale, le lik'hemik'hale, le ho netefatsa ts'ebetso ea nako e telele.
- Ho fapanyetsana:Li-polymers tse phahameng li tla ka mekhoa e fapaneng, ho kenyeletsoa likhoele, li-fibers, likhetla le li-shellek, litloa ka mefuta e mengata ea litloaelo tsa moralo.
- Khanyetso ea Corrosanion:Ho fapana le litlolo, lihloela tse matla li hanyetsanang le lihlapi, ho fokotsa litlhoko tsa tokiso.
- Rala ho feto-fetoha ha maemo:Li-polymers tse ngata tse phahameng li ka siuoa hantle, li bopehile 'me li entsoe ka letsoho, li nolofalletsa meralo e rarahaneng.
Likopo tsa Polymers tse phahameng tsa matla
Matla a ikhethang le ho se tšoanelehe ha li-polymers tsena li li etsa hore li lokele likopo tse fapaneng Indies:
- Aerospace:Li-polymers tse phahameng li sebelisoa likarolong tsa lifofane, literata tse futsang tsa fusela, le lintho tse hlophisitsoeng ka lebaka la lihlahisoa tsa bona tse bobebe.
- Likoloi:Likarolo tse kang lithupa, masala le likarolo tse kahare hangata li sebelisa lihloli tsa matla a maholo bakeng sa melemo ea bona ea boima le ho fetoha le maemo.
- Kaho:Pipipes, membrane e marulelong le matla a sebopeho, 'me sebopeho sa sebopeho se ka holisa matla le ho tšoarella ha li-polymers tse phahameng.
- Lihlahisoa tsa lipapali:Ho tsoa ka lisebelisoa tsa ho bapala tse phahameng tse kang skis le baesekele ea skis le baesekele ho e sirelletsa, polyers e ntlafatsa ts'ebetso le polokeho.
- Lisebelisoa tsa Biomedical:Manonyeletso a Maiketsetso, ho kenella, le lisebelisoa tsa bongaka li rua molemo lipelong tse sa sebetseng hantle le tse matla tse matlafatsang tsa poelsmer tse ikhethang.
Bokamoso ba Polymers e phahameng
Nts'etsopele ea li-polymers tse phahameng ke ho lelekisa ho sa feleng. Patlisiso e shebileng mabapi le ho theha li-polymistors tse nang le li-raticams tse ngata tse matlafatsang, li ile tsa ntlafala le ho hana ho hongata. Ho feta moo, ho kenyelletsa litloaelo tse tsitsitseng ho etsa hore li-poltrimers tse phahameng li be le tataiso bakeng sa tšusumetso e fokotsehileng ea tikoloho.
Sephetho
Lipotoketsi tse phahameng tsa matlapi li phetha karolo e fetolelang boenjiniere le boqapi ba kajeno. Matla a bona a ikhethang, ho feto-phello, le thepa e bobebe ea mahlo e fana ka melemo ea bohlokoa ka lisebelisoa tsa setso. E le tsoelo-pele ea theknoloji, lithobusi tse phahameng li tla tsoela pele ho fetola, tse nolofalletsang ho ba matla, tse bobebe le tse tsitsitseng bakeng sa lits'ebeliso tse fapaneng.
