He nui nā pono o ka Fiberglass e like me ka ikaika kiʻekiʻe a me ke kaumaha māmā, ke kūpaʻa i ka pala, ke kūpaʻa wela kiʻekiʻe, a me ka hana insulation uila maikaʻi. ʻO ia kekahi o nā mea i hoʻohui ʻia i hoʻohana pinepine ʻia. I ka manawa like, ʻo Kina nō hoʻi ka mea hana fiberglass nui loa o ka honua.
1. He aha ka fiberglass?
He mea metala ʻole ka Fiberglass me ka hana maikaʻi loa. He mineral kūlohelohe ia me ka silica ma ke ʻano he mea maka nui, e hoʻohui ana i nā mea maka mineral oxide metala kikoʻī. Ma hope o ke kāwili like ʻana, hoʻoheheʻe ʻia i ka mahana kiʻekiʻe, a kahe ke aniani hoʻoheheʻe ʻia ma o ka nozzle leak. , ma lalo o ka hana o ka ikaika huki wikiwiki, huki ʻia a hoʻomaʻalili koke ʻia a hoʻopaʻa ʻia i loko o nā olonā hoʻomau maikaʻi loa.
ʻO ke anawaena o ka monofilament fiberglass mai kekahi mau microns a i iwakālua microns, ʻo ia hoʻi he 1/20-1/5 o ka lauoho. Ua hana ʻia kēlā me kēia pūʻolo o nā kaula fiber me nā haneli a i ʻole nā tausani o nā monofilaments.
Nā waiwai kumu o ka fiberglass:
He ʻano cylindrical ke ʻano me kahi ʻili laumania, he pōʻai piha ka ʻāpana kea, a he ikaika ka hiki ke hāpai i ka ʻāpana kea pōʻai; he liʻiliʻi ke kūpaʻa o ke kinoea a me ka wai, akā ʻo ka ʻili laumania e hoʻolilo i ka ikaika cohesion fiber i mea liʻiliʻi, ʻaʻole kūpono i ka hui pū ʻana me ka resin; ʻo ka nui o ka density ma 2.50-2.70 g/cm3, hilinaʻi nui ia i ka haku mele aniani; ʻoi aku ka ikaika o ka tensile ma mua o nā olonā kūlohelohe ʻē aʻe a me nā olonā synthetic; mea palupalu, ʻuʻuku loa kona elongation i ka haki; ʻoi aku ka maikaʻi o ke kūpaʻa wai a me ka waikawa, ʻoiai he haʻahaʻa ke kūpaʻa alkali. ʻOkoʻa.
2. Ka Hoʻokaʻawale ʻana oolonāaniani
Mai ka hoʻokaʻawale ʻana o ka lōʻihi, hiki ke hoʻokaʻawale ʻia i ka fiberglass aniani hoʻomau, ka fiberglass pōkole (fiberglass lōʻihi paʻa) a me ka fiberglass lōʻihi (LFT).
3. Ka hoʻohana ʻana o ka fiberglass
He ikaika kiʻekiʻe ka Fiberglass, modulus elasticity kiʻekiʻe, non-flammability, pale kemika, hoʻemi wai haʻahaʻa, a me ka hana hana maikaʻi. , hoʻohana nui ʻia ma nā ʻano like ʻole.
Ua māhele ʻia ka fiberglass haole i ʻehā mau māhele e like me ka hoʻohana ʻana i ka huahana: nā mea hoʻoikaika no nā plastics thermosetting i hoʻoikaika ʻia, nā mea hoʻoikaika fiberglass no nā thermoplastics, nā mea hoʻoikaika gypsum sima, nā mea lole fiberglass, nona nā mea hoʻoikaika he 70-75%, nā mea lole fiberglass he 25-30%. Mai ka manaʻo o ke koi ma lalo, ʻo ke kahua hana he 38% (me nā pipelines, ka desalination wai kai, ka mehana hale a me ka pale wai, ka mālama wai, a pēlā aku), nā moʻolelo halihali he 27-28% (nā waʻa, nā kaʻa, ke kaʻaahi wikiwiki, a pēlā aku), a ʻo ka helu uila he 17%.
I ka hōʻuluʻulu ʻana, ʻo nā kahua noi o ka fiberglass e pili ana i ka halihali, nā mea kūkulu hale, ka ʻoihana uila, ka ʻoihana mīkini, ka ʻoihana petrochemical, ka moʻomeheu leʻaleʻa a me ka ʻenehana pale aupuni.
