Me whakamārama tātou he aha i toa ai tēnei rauemi, me ngā kōrero a te pikinga o ngā kaweake o Haina mō te tono o te ao.
Te Whakataetae Kevlar vs. UHMWPE: He aha i toa ai te mama?
Mō ngā tekau tau, i whakamahia te Kevlar hei hanga i te nuinga o te wā nā tōna kaha kume me tōna mimiti pūngao whakamiharo. Engari ko ngā kaiwhakamahi o ēnei rā—mai i ngā āpiha pirihimana ki ngā kaiwhaiwhai haumaru ā-iwi—e hiahia ana ki te nui atu i te tiakitanga anake; e hiahia ana rātou ki ngā taputapu kāore e taumaha i a rātou i ngā wā roa, i ngā wā ohorere rānei. Koinei te wāhi e tiaho ai te UHMWPE.
Painga Taumaha:He mama ake te UHMWPE i te Kevlar tae atu ki te 30% mō te taumata tiaki ōrite. Ka taea e te koti UHMWPE NIJ IIIA paerewa te taumaha ki te 1.5kg noa iho, ki te whakaritea ki te 2kg+ mō ngā Kevlar ōrite. Mō te pirihimana e tirotiro ana i ngā huringa 8-hāora, ka whakakorea e taua rerekētanga te ngenge me te whakapai ake i te nekenekehanga—he mea nui mō te urupare tere ki ngā āhuatanga ohorere.
Whakarei ake i te manawanui:E rima ngā wā e pai ake ai te ātete a te UHMWPE ki ngā hihi UV, ki ngā matū, me te pakū i te Kevlar. Kāore e pirau i muri i te pānga o te rā ki ngā tirotiro o waho i te tonga-mā-uru o Amerika) i te haumākū o te takutai moana rānei (he wero i ngā rohe Pākehā pērā i te UK me Parani), ā, ka roa ake te roa o te ora o te taputapu mā te 2–3 tau i te toharite.
Te ōritetanga o te mahi:Kaua e whakaaro he ngoikore te māmā. Tekau mā rima ngā wā o te kaha kume o te UHMWPE i te maitai, he rite, he nui atu rānei i te kaha o Kevlar ki te aukati i ngā matā 9mm me te .44 Magnum—e tutuki ana i ngā paerewa tiaki tino pakari a NIJ (US) me EN 1063 (Europe).
