He nui nā pōmaikaʻi o Fiberglass e like me ka ikaika kiʻekiʻe a me ke kaumaha māmā, ka pale ʻana i ka corrosion, ke kūpaʻa wela kiʻekiʻe, a me ka hoʻokō ʻana i ka uila uila. ʻO ia kekahi o nā mea i hoʻohana mau ʻia. I ka manawa like, ʻo Kina ka mea hana nui loa o ka honua i ka fiberglass.
1. He aha ka fiberglass?
ʻO Fiberglass kahi mea metala ʻole me ka hana maikaʻi loa. He mineral maoli ia me ka silica ma ke ʻano he mea maka nui, e hoʻohui ana i nā mea waiwai metala oxide. Ma hope o ka hui like ʻana, hoʻoheheʻe ʻia i ka wela kiʻekiʻe, a kahe ke aniani i hoʻoheheʻe ʻia ma ka nozzle leak. , Ma lalo o ka hana a ka ikaika huki huki kiʻekiʻe, ua huki ʻia a hoʻomaʻalili wikiwiki a hoʻopaʻa ʻia i loko o nā kaula hoʻomau maikaʻi loa.
ʻO ke anawaena o ka fiberglass monofilament mai kahi liʻiliʻi a i iwakālua microns, ʻo ia ka mea like me 1/20-1/5 o ka lauoho. ʻO kēlā me kēia pūʻolo o nā kaula fiber i haku ʻia me nā haneli a i ʻole mau tausani monofilament.
Nā waiwai kumu o ka fiberglass:
ʻO ka hiʻohiʻona he ʻano cylindrical me kahi ʻili maʻemaʻe, ʻo ka ʻāpana keʻa he pōʻai piha, a ʻo ka ʻāpana keʻa pōʻai he ikaika ka lawe ʻana i ka ukana; liʻiliʻi ke kinoea a me ka wai e hele ana, akā ʻo ka ʻili maʻemaʻe e liʻiliʻi ai ka ikaika cohesion fiber, ʻaʻole kūpono i ka hui ʻana me ka resin; ʻO ka mānoanoa maʻamau i 2.50-2.70 g/cm3, pili nui i ka haku aniani; ʻoi aku ka kiʻekiʻe o ka ikaika tensile ma mua o nā fiber maoli a me nā fiber synthetic; mea palupalu, liʻiliʻi loa kona elongation ma ka haki; ʻoi aku ka maikaʻi o ka pale ʻana i ka wai a me ka ʻakika, ʻoiai ʻoi aku ka haʻahaʻa o ke kūpaʻa alkali. ʻokoʻa.
2. Hoʻokaʻawale opulupuluaniani
Mai ka hoʻokaʻawale ʻana o ka lōʻihi, hiki ke hoʻokaʻawale ʻia i ka fiber aniani mau, ka fiberglass pōkole (fixed long fiberglass) a me ka fiberglass lōʻihi (LFT).
3. Hoʻohana i ka fiberglass
Loaʻa i ka Fiberglass ka ikaika tensile kiʻekiʻe, ka modulus kiʻekiʻe o ka elasticity, non-flammability, ke kūpaʻa kemika, ka haʻahaʻa haʻahaʻa o ka wai, a me ka hana hana maikaʻi. , hoʻohana nui ʻia ma nā ʻano hana like ʻole.
Hoʻokaʻawale ʻia ka fiberglass haole i ʻehā mau ʻāpana e like me ka hoʻohana ʻana i ka huahana: hoʻoikaika i nā mea no ka hoʻoikaika ʻana i nā plastic thermosetting, fiberglass reinforcing mea no ka thermoplastics, sima gypsum reinforcing mea, fiberglass textile mea, nona ka hoʻoikaika ʻana i nā mea waiwai no 70-75%, fiberglass textile mea waiwai no 25-30%. Mai ka hiʻohiʻona o ka noi o lalo, ʻoi aku ka nui o ka waiwai ma kahi o 38% (me nā pipelines, ka desalination o ke kai, ka mahana o ka hale a me ka wai ʻole, ka mālama wai, a me nā mea ʻē aʻe), ʻo ka lawe ʻana ma kahi o 27-28% (yachts, kaʻa kaʻa, high-speed rail, etc.), a me nā mea uila ma kahi o 17%.
I ka hōʻuluʻulu ʻana, ʻo nā papa noi o fiberglass ka mea maʻamau e pili ana i ka halihali, nā mea kūkulu hale, ʻoihana uila, ʻoihana mīkini, ʻoihana petrochemical, moʻomeheu leʻaleʻa a me ka ʻenehana pale aupuni.
