1.Thepa ea fiber ea Aramid

Lebitso le felletseng la fiber ea aramid ke faeba e nkhang hamonate ea polyamide.Ke polymer e nang le mela e entsoeng ka lihlopha tse nkhang hamonate le lihlopha tsa amide.E na le thepa e ntle ea mochini, sebopeho sa lik'hemik'hale se tsitsitseng, thepa e ntle ea mochini, matla a holimo-limo le modulus e phahameng., ho hanyetsa mocheso o phahameng, ho hanyetsa acid le alkali, boima bo bobebe, ho hanyetsa ho apara le lintho tse ling tse babatsehang.E 'nile ea sebelisoa haholo masimong a kang lisebelisoa tse sireletsang likulo, sefofane, kaho le lisebelisoa tsa elektronike.

Leha ho le joalo, fiber ea aramid e boetse e na le mefokolo e 'meli e meholo

(1) Fiber ea Aramid e na le khanyetso e fokolang ea UV.Mahlaseli a ultraviolet (khanya ea letsatsi) a baka ho senyeha ha likhoele tsa aramid.Ka hona, ho hlokahala lesela le sireletsang, le ka bang topcoat kapa lesela la lintho tse bonahalang, mohlala, likhoele tsa aramid li atisa ho kenngoa ka lera le sireletsang.

(2) Fiber ea Aramid e na le hygroscopicity e batlang e le holimo (ho fihlela ho 6% ea boima ba eona), kahoo lisebelisoa tse nang le fiber ea aramid li hloka ho sireletsoa hantle, joalo ka li-topcoats hangata li sebelisoa ho fokotsa hygroscopicity.Ho phaella moo, tšebeliso ea mefuta e itseng ea aramid e fokotsa ho monyela ha metsi ha motsoako ha o le tlas'a metsi, joalo ka Kevlar 149 kapa Armos.

2.PE lisebelisoa tsa fiber

PE ha e le hantle e bua ka UHMW-PE, e leng polyethylene e boima ba molek'hule e phahameng haholo.Ke fiber ea tlhaho e sebetsang hantle haholo e ntlafalitsoeng mathoasong a lilemo tsa bo-1980.Hammoho le fiber ea carbon le aramid, e tsejoa e le likhoele tse tharo tse kholo tsa theknoloji e phahameng lefatšeng kajeno.E na le botsitso bo phahameng haholo 'me e thata haholo ho e theola, e bakang tšilafalo e tebileng ea tikoloho.Empa ke hantle ka lebaka la tšobotsi ena e fetohang thepa e loketseng ho etsa lihlomo tsa 'mele.Ho feta moo, e hanela mocheso o tlase, leseli la UV le metsi.

Mabapi le ho thibela likulo tsa lebelo le tlaase, ts'ebetso ea bulletproof ea PE fiber e ka ba 30% e phahameng ho feta ea aramid;mabapi le ho thibela likulo tsa lebelo le phahameng, ts'ebetso ea fiber ea PE ke 1.5 ho makhetlo a 2 a aramid.Ho ka boleloa hore mefokolo ea fiber ea aramid e fetohile melemo ea fiber ea PE, 'me melemo ea fiber ea aramid e se e le betere ho fiber ea PE.Ka hona, ke mokhoa o ke keng oa qojoa oa hore PE fiber e nke sebaka sa aramid tšimong ea tšireletso.

Ehlile, fiber ea PE le eona e na le mefokolo.Boemo ba eona ba ho hanyetsa mocheso bo tlase haholo ho feta fiber ea aramid.Mocheso oa tšebeliso ea lihlahisoa tsa tšireletso ea fiber PE o ka hare ho 70 ° C (e ka finyellang litlhoko tsa 'mele oa motho le lisebelisoa, ke hore, tlhokahalo ea ho hanyetsa mocheso oa 55 ° C).Ka ntle ho mocheso ona, ts'ebetso e fokotseha ka potlako.Ha mocheso o feta 150 ° C, fiber ea PE e tla qhibiliha, 'me fiber ea aramid Fiber e ntse e ka boloka thepa e ntle ea tšireletso sebakeng sa 200 ° C, 'me ha e qhibilihe kapa e senyehile ho 500 ° C;ha e kopana le mocheso o phahameng ka holimo ho 900 ° C, e tla etsoa ka carbonized ka ho toba ho etsa lera la ho thibela mocheso.Tsena ha li fumanehe lihlahisoa tse sireletsang fiber tsa PE mme li fetohile melemo e ikhethang ea lihlahisoa tsa aramid.
