I-Magic aramid fiber

I-Aramid fiber yazalwa ngasekupheleni kwawo-1960.Ekuqaleni kwakungaziwa njengento yokuthuthukiswa kwendawo yonke kanye nempahla ebalulekile yamasu.Ngemva kokuphela kweMpi Yomshoshaphansi, i-aramid fiber, njenge-high-tech fiber material, yasetshenziswa kakhulu emikhakheni yomphakathi, futhi kancane kancane yaziwa.Kunezinhlobo ezimbili zemicu ye-aramid enenani elingokoqobo kakhulu: enye i-meta-aramid fiber ene-zigzag molecular chain chain, ebizwa ngokuthi i-aramid fiber 1313 e-China;Enye ifayibha ye-para-aramid ene-linear molecular chain chain, ebizwa ngokuthi i-aramid fiber 1414 e-China.

Njengamanje, i-aramid fiber iyimpahla ebalulekile yokuvikela izwe kanye nemboni yezempi.Ukuze kuhlangatshezwane nezidingo zempi yesimanje, amavesti angangenwa izinhlamvu emazweni athuthukile njenge-United States neBrithani enziwe nge-aramid fiber.I-lightweight ye-aramid bulletproof vests nezigqoko zokuvikela ithuthukise ngempumelelo ikhono lokuphendula ngokushesha kanye nobungozi bombutho.EMpini YaseGulf, izinhlanganisela ze-aramid zazisetshenziswa kakhulu yizindiza zaseMelika nezaseFrance.Ngaphezu kwezicelo zezempi, isetshenziswe kabanzi njenge-high-tech fiber material ku-aerospace, i-electromechanical, ukwakhiwa, izimoto, izimpahla zezemidlalo nezinye izici zomnotho wezwe.Ezindizeni nasemkhathini, i-aramid fiber yonga uphethiloli wamandla amaningi ngenxa yesisindo sayo esilula namandla ayo aphezulu.Ngokusho kwedatha yangaphandle, ikhilogremu ngayinye yokunciphisa isisindo ngesikhathi sokwethulwa kwemikhumbi-mkhathi isho ukwehla kwezindleko nge-$1 million.Ngaphezu kwalokho, ukuthuthuka okusheshayo kwesayensi nobuchwepheshe kuvula indawo entsha yomphakathi ye-aramid fiber.Ngokwemibiko, imikhiqizo ye-aramid isetshenziselwa amavesti nezigqoko ezivikela izinhlamvu, ezibalelwa ku-7-8%, futhi izinto ze-aerospace nezinto zezemidlalo zibalelwa ku-40%.Izinto zokwakha zamathambo ethaya, izinto zebhande lokuthutha kanye nezinye izici zibalelwa ku-20%, kanti izintambo ezinamandla amakhulu zenza cishe u-13%.Imboni yamasondo nayo yaqala ukusebenzisa intambo ye-aramid ngobuningi ukuze kuncishiswe isisindo kanye nokumelana nokugoqa.

I-Aramid, eyaziwa ngokugcwele ngokuthi "i-polyphenylphthalamide" futhi ebizwa ngokuthi i-Aramid fiber ngesiNgisi, iwuhlobo olusha lwe-high-tech fiber synthetic fiber, enezakhiwo ezinhle kakhulu ezifana namandla aphezulu, i-modulus ephezulu, ukumelana nokushisa okuphezulu, ukumelana ne-asidi ne-alkali, isisindo esilula, ukwahlukanisa, umjikelezo wempilo ende wokumelana nokuguga, njll. Amandla ayo makhulu kuno-28g/denier, okuyizikhathi eziphindwe ka-5-6 kunezocingo lwensimbi olusezingeni eliphezulu, izikhathi ezi-2 kunocingo olunamandla kakhulu enayiloni, izikhathi ezingu-1.6 ye-graphite enamandla amakhulu futhi izikhathi ezi-3 kune-glass fiber.I-modulus iphindwe izikhathi ezingu-2-3 kuneyensimbi yensimbi noma i-fiber yengilazi, ukuqina kuphindwe izikhathi ezingu-2 kocingo lwensimbi, futhi isisindo sicishe sibe yi-1/5 kuphela yocingo lwensimbi.Ukumelana nokushisa okuphezulu okuhle kakhulu, izinga lokushisa lokusetshenziswa kwesikhathi eside lama-degree angama-300, ukumelana nokushisa okuphezulu kwesikhashana kwe-586 degrees.Ukutholakala kwe-aramid fiber kuthathwa njengenqubo ebaluleke kakhulu yomlando emkhakheni wezinto zokwakha.
