ʻO ka Glass Mat Reinforced Thermorplastic (GMT) e pili ana i kahi mea hui hou, mālama ikehu a māmā hoʻi e hoʻohana ana i ka resin thermoplastic ma ke ʻano he matrix a me ka moena fiber aniani ma ke ʻano he iwi i hoʻoikaika ʻia. He mea hui ikaika loa ia i kēia manawa ma ka honua. Ua manaʻo ʻia ka hoʻomohala ʻana o nā mea ʻo ia kekahi o nā mea hou o ke kenekulia. Hiki i ka GMT ke hana i nā huahana pepa semi-finished, a laila hana pololei iā lākou i nā huahana o ke ʻano i makemake ʻia. Loaʻa iā GMT nā hiʻohiʻona hoʻolālā paʻakikī, kūpaʻa hopena maikaʻi loa, a maʻalahi ke hōʻuluʻulu a hana hou. Hoʻomaikaʻi ʻia no kona ikaika a me ka māmā, e lilo ia i mea hoʻonohonoho kūpono e pani i ke kila a hōʻemi i ka nuipa.
1. Nā pono o nā mea GMT
1. Ikaika kikoʻī kiʻekiʻe: Ua like ka ikaika o GMT me ko nā huahana FRP polyester i kau lima ʻia. ʻO kona nui he 1.01-1.19g/cm, ʻoi aku ka liʻiliʻi ma mua o ka FRP thermosetting (1.8-2.0g/cm), no laila he ikaika kikoʻī kiʻekiʻe aʻe.
2. Māmā a mālama i ka ikehu: Hiki ke hoʻemi ʻia ke kaumaha ponoʻī o ka puka kaʻa i hana ʻia me ka mea GMT mai 26Kg a i 15Kg, a hiki ke hoʻemi ʻia ka mānoanoa o ke kua, i hoʻonui ʻia ai ka hakahaka o ke kaʻa. ʻO ka hoʻohana ʻana i ka ikehu he 60-80% wale nō o nā huahana kila a me 35 o nā huahana alumini. -50%.
3. Ke hoʻohālikelike ʻia me ka thermosetting SMC (sheet molding compound), loaʻa i ka mea GMT nā pono o ke kaʻina hana molding pōkole, ka hana hopena maikaʻi, ka hana hou ʻana a me ka wā mālama lōʻihi.
4. Hana hopena: ʻO ka hiki o GMT ke omo i ka hopena he 2.5-3 mau manawa kiʻekiʻe ma mua o SMC. Ma lalo o ka hana o ka hopena, ʻike ʻia nā dents a i ʻole nā māwae i loko o SMC, kila a me ka alumini, akā palekana ʻo GMT.
5. ʻOʻoleʻa kiʻekiʻe: Loaʻa i ka GMT ka lole GF, hiki ke mālama i kona ʻano ʻoiai inā he hopena o 10mph.
2. Ka hoʻohana ʻana i nā mea GMT ma ke kahua kaʻa
Loaʻa i ka pepa GMT ka ikaika kikoʻī kiʻekiʻe, hiki ke hana i nā ʻāpana māmā, a he kūʻokoʻa hoʻolālā kiʻekiʻe, hoʻopili ikaika i ka ikehu kuʻi, a me ka hana hana maikaʻi. Ua hoʻohana nui ʻia ia ma ka ʻoihana kaʻa ma waho mai ka makahiki 1990. I ka hoʻomau ʻana o nā koi no ka hoʻokele wahie, ka hana hou ʻana a me ka maʻalahi o ka hana ʻana, e hoʻomau ka ulu ʻana o ka mākeke no nā mea GMT i hoʻohana ʻia ma ka ʻoihana kaʻa. I kēia manawa, hoʻohana nui ʻia nā mea GMT ma ka ʻoihana kaʻa, ʻo ia hoʻi nā mōlina noho, nā bumpers, nā dashboards, nā uhi mīkini, nā pale pākahiko, nā pedals, nā wēlau mua, nā papahele, nā kiaʻi, nā puka hope, nā kaupaku kaʻa, nā pale ukana, nā pale lā, nā ʻūlū huila a me nā ʻāpana ʻē aʻe.
