Lintho tse bonahalang tsa nylone sebelisoa haholo, li-stockings tse nyane ho isa ho tsa nylon, likarolo tse kholo tsa enjene ea koloi, joalo-joalo, li kentse likarolo tsohle tsa bophelo ba rona.Libaka tse fapaneng tsa ts'ebeliso, litlhoko tsa thepa ea thepa ea nylon le tsona li fapane, joalo ka ho hanyetsa mocheso o phahameng, ho hanyetsa ho roala le ho hanyetsa tšusumetso, khanyetso ea moemeli oa lik'hemik'hale, pepeneneng le ho tiea.
Nylon e tloaelehileng, ka kakaretso e bua ka PA6, PA66 mefuta e 'meli e tloaelehileng.Nylon e tloaelehileng e ntlafalitsoeng, e thibelang lelakabe le liphetoho tse ling e ntse e tla ba le mefokolo e kholo, joalo ka hydrophilicity e matla, ho hanyetsa mocheso o phahameng, ho se pepesehe hantle joalo-joalo, ho fokotsa lits'ebetso tse ngata.
Ka hona, molemong oa ho ntlafatsa mefokolo le ho eketsa litšoaneleho tse ncha, ka kakaretso ka ho hlahisa li-monomers tse ncha tsa maiketsetso, re ka fumana letoto la nylon e khethehileng e nang le litšobotsi tse fapaneng tse ka kopanang le linako tse fapaneng tsa ts'ebeliso, tse arotsoeng haholonylon ea mocheso o phahameng, nylon e telele ea k'habone, nylon e bonaletsang, lisebelisoa tse thehiloeng ho biolone le elastomer ea nylon joalo-joalo.
Joale, a re ke re bue ka lihlopha tsa nylon e khethehileng, litšobotsi tsa bona le lisebelisoa.
Lihlopha le mehlala ea tšebeliso eanylon e khethehileng
1. Ho hanyetsa mocheso o phahameng -- nylon ea mocheso o phahameng
Pele ho tsohle, nylon ea mocheso o phahameng e bolela lisebelisoa tsa nylon tse ka sebelisoang tikolohong e ka holimo ho 150 ° C nako e telele.
Ho hanyetsa mocheso o phahameng oa nylon ea mocheso o phahameng hangata ho fumanoa ka ho hlahisa li-monomers tse thata tse nkhang hamonate.Mohlala, nylon e nkhang hamonate, e tloaelehileng ka ho fetisisa ke Kevlar ea DuPont, e lokiselitsoeng ke karabelo ea p-benzoyl chloride e nang le p-phenylenediamine kapa p-amino-benzoic acid, e bitsoang PPTA, e ka boloka matla a matle ho 280 °. C bakeng sa 200h.
Leha ho le joalo, kaofela monko o monate holimonylon ea mochesoha e ntle ho sebetsa 'me ho thata ho finyella ho bōptjoa ha ente, kahoo nylon e monko o monate oa mocheso o phahameng o kopantsoeng le aliphatic le monko o monate o ratoa haholoanyane.Hajoale, mefuta e mengata ea nylon ea mocheso o phahameng, joalo ka PA4T, PA6T, PA9T, PA10T, joalo-joalo, ke nylon e nkhang hamonate ea mocheso o phahameng oa mocheso o entsoeng ka polymerized ho tloha ketane e otlolohileng ea aliphatic diamine le terephthalic acid.
Nylon ea mocheso o phahameng e sebelisoa haholo likarolong tsa likoloi, likarolo tsa mechine le likarolo tsa motlakase / tsa elektroniki.
2. Matla a phahameng - nylon e telele ea carbon chain
Ea bobeli ke nylon e telele ea k'habone, eo ka kakaretso e bolelang lisebelisoa tsa nylon tse nang le li-methylene tse fetang 10 ka ketane ea limolek'hule.
Ka lehlakoreng le leng, nylon e telele ea carbon nylon e na le lihlopha tse ngata tsa methylene, kahoo e na le boima bo phahameng le bonolo.Ka lehlakoreng le leng, phokotso ea bongata ba lihlopha tsa amide ka ketane ea limolek'hule e fokotsa haholo hydrophilicity mme e ntlafatsa botsitso ba eona, 'me mefuta ea eona ke PA11, PA12, PA610, PA1010, PA1212 joalo-joalo.
Joalo ka mefuta e mengata ea bohlokoa ea lipolasetiki tsa boenjiniere, nylon e telele ea k'habone e na le melemo ea ho monya metsi a tlase, ho hanyetsa mocheso o tlase, boholo bo tsitsitseng, boima bo botle, ho monyeha ho hana ho ts'oenyeha, joalo-joalo, 'me e sebelisoa haholo likoloing, puisanong, mecheng. , lisebelisoa tsa elektroniki, sepakapaka, thepa ea lipapali le masimo a mang.
3. Ponaletso e phahameng - nylon e bonaletsang
Nylon e tloaelehileng hangata e na le chebahalo e phatsimang, phetiso ea leseli lipakeng tsa 50% le 80%, 'me phetiso ea khanya ea nylon e bonaletsang hangata e feta 90%.
Nylon e bonaletsang e ka fetoloa ka mekhoa ea 'mele le ea lik'hemik'hale.Mokhoa oa 'mele ke ho eketsa nucleating agent le ho fokotsa boholo ba lijo-thollo ho ea ho leqhubu la maqhubu a bonahalang ho fumana nylon e hlakileng ea microcrystalline.Mokhoa oa lik'hemik'hale ke ho hlahisa monoma e nang le sehlopha se lehlakoreng kapa sebopeho sa selikalikoe, ho senya tloaelo ea ketane ea limolek'hule, le ho fumana nylon e hlakileng ea amorphous.
Nylon e bonaletsang e ka sebelisoa bakeng sa seno le liphutheloana tsa lijo, empa hape e ka etsa lisebelisoa tsa optical le likarolo tsa komporo, tlhahiso ea indasteri ea ho lekola Windows, fensetere ea sesebelisoa sa X-ray, lisebelisoa tsa metering, polokelo ea moetso oa motlakase oa motlakase, sekoaelo sa mabone a khethehileng, lisebelisoa le lijana tsa lijo. .
4. Moshoelella - Bio-e thehiloeLisebelisoa tsa Nylon
Hajoale, boholo ba li-monomer tsa maiketsetso tsa mefuta ea nylon li tsoa tseleng ea tlhoekiso ea peterole, 'me monomer ea maiketsetso ea nylon e thehiloeng ho bio e tsoa tseleng ea ho ntša thepa e tala, joalo ka Arkema ka tsela ea ho ntša oli ea castor ho fumana amino undecanoic. asiti ebe nylon ea maiketsetso 11.
Ha ho bapisoa le nylon ea setso e entsoeng ka oli, nylon ea thepa e thehiloeng ho bio ha e na feela melemo ea bohlokoa ea khabone e tlase le tikoloho, empa hape e ka fihlela litlhoko tse fapaneng tsa ts'ebetso ea tharollo, joalo ka Shandong Kaisai bio-based PA5X series, Arkema. Letoto la Rilsan likarolong tsa likoloi, lisebelisoa tsa elektroniki le indasteri ea khatiso ea 3D le likarolo tse ling li sebelisitsoe ka katleho.
5.Elastomer e phahameng -- nylon elastomer
Nylon elastomere bua ka mefuta ea nylon e nang le botsitso bo phahameng, boima bo bobebe le litšobotsi tse ling, empa ho bohlokoa ho bolela hore sebopeho sa ketane ea nylon elastomer ha se likarolo tsohle tsa ketane ea polyamide, le likarolo tsa ketane ea polyether kapa polyester, mofuta o tsebahalang haholo oa khoebo ke polyether block amide. (PEBA).
Litšobotsi tsa ts'ebetso ea PEBA ke matla a phahameng a ho tsieleha, ho hlaphoheloa hantle ha rekere, matla a matla a mocheso o tlase, ho hanyetsa mocheso o tlase haholo, ts'ebetso e ntle ea antistatic, joalo-joalo, e sebelisoang lieta tsa ho hloa lithaba, lieta tsa ski, lisebelisoa tsa ho khutsisa le li-catheter tsa bongaka.
