Aramid fiberis high-performance synthetic fiber, ine ultra-high simba, high modulus, high-temperature resistance, acid uye alkali resistance, lightweight, uye humwe unhu hwakanaka. Simba rayo rinogona kusvika 5-6 nguva yewaya yesimbi, modulus inokwana 2-3 yewaya yesimbi kana girazi faibha, kusimba kunosvika kaviri kune waya yesimbi, uye uremu hunosvika 1/5 chete hwewaya yesimbi. Pakupisa kwakanyanya kwe560 ℃, aramid fibers inogona kuramba yakatsiga, isingaore, uye hainyungudika. Mukuwedzera, ine yakanaka yekuvharisa uye inorwisa-kuchembera zvinhu, uye hupenyu hurefu hwebasa. Parizvino, midziyo isingapindi bara (yakadai semabhati asingapindi bara, uye ngowani dzemabara) inowanzo shandisa.aramid fiber machira. Pakati pavo, low-gravity aramid fiber plain fabric ndeimwe yezvinhu zvakakosha mumunda webulletproofing. Zvichienzaniswa nehembe dzemukati dzenaironi dzechinyakare uye ngowani dzesimbi, hembe dzemukati dzisingapindi bara uye ngowani dzine aramid fiber dzakawedzerwa hadzisi diki uye dzakareruka chete asiwo 40% inoshanda zvakanyanya pakurwisa mabara.
Nheyo yekushanda yemabhuruku evhavha inogona kunzwisiswa neiyi nzira: kana bara rarova jira rejira revheti, kuvhunduka uye masaisai ekumanikidza anogadzirwa padanho rekukanganisa. Aya masaisai kuburikidza nekukurumidza kupararira uye kupararira kwefiber, anogona kuvhara muhuwandu hwefibers, uye ipapo munzvimbo yakakura kuti atore simba rekuvhunduka. Uku kunyudzwa kwesimba kwakawedzera kunonyatso kudzikamisa kukanganiswa kwemabara pamuviri wemunhu, nekudaro kuona kudzivirira kwevhavha.
Bulletproof zvinhu uye kuita kwayo kwakanakisa
Mwongo wemabhururu evhavha uri mune yakakwira-simba fiber zvinhu zvavanoshandisa, iyo para-aramid fibers, inozivikanwawo separa-aromatic polyamide fibers, chinhu chinoremekedzwa zvakanyanya. Yayo yakanyanya symmetrical kemikari chimiro inopa iyo molecular cheni kusimba kwakanyanya, ichiita kuti ive yakasiyana zvakanyanya kubva kune yakajairwa inoshanduka ketani mapolymers maererano nekunyungudika, rheological zvimiro, uye kugadzirisa.
Para-aramid fibers inozivikanwa nekunaka kwayo kwemuviri uye mekiniki zvivakwa, zvinosanganisira yekupedzisira-yepamusoro simba, yakakwira modulus, uye isina huremu. Simba ravo chairo rakareba zvakapetwa kashanu kana katanhatu pane rewaya yesimbi yakajairwa, uye modulus yavo chaiyo inodarika waya yesimbi nechikamu cheviri kana matatu. Mukuwedzera, mafiber anoratidza zvakanakisa kupisa zvivakwa, nekukwirira-kupisa kupikisa, kuwedzera kwakaderera, uye kuderera kwekushisa conductivity, uye kusapisa kana kunyungudika. Para-aramid fibers inozivikanwawo se "bulletproof fibers" nekuda kwekudzivirira kwayo kwakanaka, kusaita ngura, uye kuramba kuchembera.
Zvikumbiro uye Zvinotarisirwa zvePara-Aramid Fiber
Para-aramid fiber, chinhu chakakosha muindasitiri yekudzivirira uye yemauto, inoshandiswa zvakanyanya pasi rese. Zvinoenderana nenhamba, chikamu chearamid mune inodzivirira fiber muUS inopfuura 50% uye 10% muJapan. Hunhu hwayo husina huremu hunogadzira maaramid bulletproof vests nengowani, izvo zvinogona kuvandudza zvakanyanya kugona kweuto kupindura. Pamusoro pezvo, para-aramid inoshandiswa zvakanyanya mumotokari, nharembozha, aerospace, uye mitambo yekunze nekuda kwekuita kwayo kwakanaka.
