ʻO ka Polybutylene terephthalate(PBT)) he polyester saturated thermoplastic semi-crystalline, ma ke ʻano he keʻokeʻo waiū, he paʻa granular ma ka mahana o ka lumi, hoʻohana pinepine ʻia i ka hana ʻana o nā mea uhi lua thermoplastic uwea optical.
ʻO ka uhi lua o ka fiber optical kahi hana koʻikoʻi loa i ka hana ʻana o ka fiber optical. I ka ʻōlelo maʻalahi, ʻo ka hoʻohui ʻana i kahi papa pale i ka uhi mua o ka fiber optical a i ʻole ka papa buffer hiki ke hoʻomaikaʻi i ka hiki o ka fiber optical ke kūʻē i ke kaumaha longitudinal a me ka radial a hoʻomaʻamaʻa i ka hana hope o ka fiber optical. Ma muli o ka kokoke o ka mea uhi i ka fiber optical, ʻoi aku ka hopena o ka hana o ka fiber optical, no laila pono ka mea uhi e loaʻa kahi coefficient hoʻonui linear liʻiliʻi, crystallinity kiʻekiʻe ma hope o ka extrusion, kemika maikaʻi a me ke kūpaʻa thermal, nā paia o loko a me waho o ka papa uhi, kahi ikaika tensile a me ka modulus Young, a he hana maikaʻi ke kaʻina hana. Ma ke ʻano laulā, ua māhele ʻia ka uhi fiber i ʻelua mau māhele: uhi wehe a me ka uhi paʻa. I waena o lākou, ʻo ka mea uhi wehe i hoʻohana ʻia i loko o ka uhi uhi wehe ʻo ia ka papa uhi lua i extruded i ke kūlana lima wehe ma waho o ka fiber uhi mua.
He mea maʻamau ka PBT me nā waiwai hoʻokumu a me ka hana ʻana maikaʻi loa, ka omo wai haʻahaʻa a me ka hana kumukūʻai kiʻekiʻe. Hoʻohana nui ʻia i lokoPBThoʻololi, kaha kiʻi uea PBT, casing, kaha kiʻiʻoniʻoni a me nā kahua ʻē aʻe. Loaʻa iā PBT nā waiwai mechanical maikaʻi (e like me ke kū'ē ʻana i ka tensile, ke kū'ē kūlou, ke kū'ē ʻaoʻao), ke kū'ē maikaʻi i ka solvent, ke kū'ē ʻaila, ke kū'ē ʻana i ka corrosion kemika, a me ka hoʻopili fiber, ka hoʻopili uwea a me nā ʻāpana ʻē aʻe o ke kaula he kūpono maikaʻi, a he hana hoʻoponopono hoʻoheheʻe maikaʻi loa, haʻahaʻa ka omo wai, kūpono ke kumukūʻai. ʻO kāna mau kūlana hana loea nui e pili ana i: ka viscosity intrinsic, ka ikaika hua, ka modulus elastic tensile a me ke kūlou, ka ikaika hopena (notch), ka coefficient hoʻonui linear, ka omo wai, ke kū'ē hydrolysis a pēlā aku.
Eia nō naʻe, me ka hoʻololi ʻana o ke ʻano o ke kaula fiber a me ke kaiapuni hana, ua kau ʻia nā koi hou aʻe no ka bushing buffer fiber. ʻO ke kiʻekiʻe o ka crystallization, ka haʻahaʻa haʻahaʻa, ka coefficient hoʻonui linear haʻahaʻa, ka paʻakikī kiʻekiʻe, ka ikaika compressive kiʻekiʻe, ke kūpaʻa kemika maikaʻi loa, ka hana hana maikaʻi, a me nā mea haʻahaʻa ke kumu kūʻai nā pahuhopu i alualu ʻia e nā mea hana kaula optical. I kēia manawa, aia nā hemahema i ka noi a me ke kumukūʻai o ka paipu beam i hana ʻia me ka mea PBT, a ua hoʻomaka nā ʻāina ʻē e hoʻohana i nā mea alloy PBT e pani i nā mea PBT maʻemaʻe, kahi i pāʻani i kahi hopena maikaʻi a me ke kuleana. I kēia manawa, ke hoʻomākaukau ikaika nei kekahi mau ʻoihana kaula kūloko nui, pono nā ʻoihana mea kaula i ka hoʻomau ʻana o ka ʻenehana, ka noiʻi a me ka hoʻomohala ʻana i nā mea hou.
ʻOiaʻiʻo, ma ka ʻoihana PBT holoʻokoʻa, ʻo nā noi kaula fiber optic e noho wale ana i kahi hapa liʻiliʻi o ka mākeke PBT. Wahi a nā kumu ʻoihana, ma ka ʻoihana PBT holoʻokoʻa, ʻo ka hapa nui o ka māhele mākeke e noho nui ʻia e nā kahua ʻelua o ke kaʻa a me ka mana. Hoʻohana nui ʻia nā mea hoʻohui, nā relays a me nā huahana ʻē aʻe i hana ʻia me nā mea PBT i hoʻololi ʻia i nā kaʻa, nā mea uila a me nā mea uila, nā lako mīkini a me nā kahua ʻē aʻe, a he mau noi ʻo PBT ma ke kahua lole, e like me ka hana ʻia ʻana o nā huluhulu o nā pulupulu niho me PBT. Eia nā noi laulā o PBT ma nā kahua like ʻole:
1. Nā kahua uila a me nā kahua uila
Hoʻohana nui ʻia nā mea PBT i nā kahua uila a me nā uila, e like me nā kumu mana, nā plug, nā kumu uila a me nā ʻāpana uila ʻē aʻe o ka hale. Ma muli o ka hana insulation maikaʻi o ka mea PBT a me ke kūpaʻa wela kiʻekiʻe, kūpono loa ia no ka pūpū, ka bracket, ka pepa insulation a me nā ʻāpana ʻē aʻe o nā lako uila a me nā lako uila. Eia kekahi, hiki ke hoʻohana ʻia nā mea PBT e hana i ka uhi hope o ka pale LCD, ka pūpū TV a pēlā aku.
2. Ke kahua kaʻa
Hoʻohana nui ʻia nā mea PBT ma ke kahua kaʻa. Ma muli o kona mau pono o ke kiʻekiʻe o ka mahana, ka pala a me ke kūpaʻa ʻana i ka ʻaʻahu, hoʻohana nui ʻia nā mea PBT i ka hana ʻana i nā ʻāpana kaʻa, e like me ka manifold intake, ka hale pamu aila, ka hale sensor, nā ʻāpana ʻōnaehana brake, a pēlā aku. Eia kekahi, hiki ke hoʻohana ʻia nā mea PBT no nā headrests noho kaʻa, nā mīkini hoʻoponopono noho, a pēlā aku.
3. ʻO ka ʻoihana mīkini
I ka ʻoihana mīkini, hoʻohana pinepine ʻia nā mea PBT e hana i nā lima hana, nā kuapo, nā pihi, a me nā mea ʻē aʻe. He ikaika mechanical maikaʻi loa ka mea PBT a me ke kūpaʻa ʻana i ka ʻaʻahu, hiki ke kū i nā ʻano ikaika mechanical like ʻole, a he kūpaʻa maikaʻi i ka pala kemika, kūpono no nā ʻāpana like ʻole i ke kahua o ka ʻoihana mīkini.
4. ʻO ka ʻoihana lako lapaʻau
He kūpaʻa maikaʻi ko ka mea PBT i ke ana wela kiʻekiʻe a me ke kūpaʻa kemika kiʻekiʻe, kahi mea kūpono loa no ka hana ʻana i nā mea lapaʻau. No ka laʻana, hiki ke hoʻohana ʻia nā mea PBT e hana i nā hale mea lapaʻau, nā paipu, nā mea hoʻohui, a me nā mea ʻē aʻe. Eia kekahi, hiki ke hoʻohana ʻia nā mea PBT e hana i nā syringe lapaʻau, nā set infusion a me nā mea hana lapaʻau like ʻole.
5. Ke kamaʻilio ʻana o ka ʻike maka
Ma ke kahua o ke kamaʻilio optical, hoʻohana nui ʻia ʻo PBT i ka hana ʻana i nā kaula optical ma ke ʻano he mea lima wehe maʻamau. Eia kekahi, hoʻohana nui ʻia nā mea PBT i nā mea optical. Ma muli o kona mau waiwai optical maikaʻi a me ke kūpaʻa wela kiʻekiʻe, hoʻohana ʻia nā mea PBT e hana i nā mea hoʻohui fiber optical, nā mōlina hoʻolaha fiber optical, a pēlā aku. Eia kekahi, hiki ke hoʻohana ʻia nā mea PBT e hana i nā aniani, nā aniani, nā puka makani a me nā ʻāpana optical ʻē aʻe.
Mai ka manaʻo o ka ʻoihana holoʻokoʻa, i nā makahiki i hala iho nei, ua kūpaʻa nā ʻoihana pili i ka hoʻomohala ʻana i nā ʻano noi like ʻole o nā ʻenehana hou a me nā huahana hou, a ua hoʻomohala ʻo PBT i ke ala o ka hana kiʻekiʻe, ka hana a me ka diversification. ʻO ka ikaika tensile resin PBT maʻemaʻe, ka ikaika kūlou a me ka modulus kūlou he haʻahaʻa, ʻaʻole hiki ke hoʻohana nui ʻia i ke kahua ʻoihana, no laila no nā pono o ke kahua ʻoihana, ʻo ka ʻoihana ma o ka hoʻololi ʻana e hoʻomaikaʻi i ka hana o PBT. No ka laʻana, ua hoʻohui ʻia ke aniani fiber i ka PBT - loaʻa i ke aniani fiber nā pono o ka hoʻohana ikaika, ke kaʻina hana hoʻopiha maʻalahi a me ke kumukūʻai haʻahaʻa. Ma ka hoʻohui ʻana i ke aniani fiber i ka PBT, ua lawe ʻia nā pono mua o ka resin PBT i ka pāʻani, a ua hoʻomaikaʻi nui ʻia ka ikaika tensile, ka ikaika kūlou a me ka ikaika hopena notch o nā huahana PBT.
I kēia manawa, ʻo nā ʻano hana nui ma ka home a me waho, ʻo ia ka hoʻololi ʻana o ka copolymerization, ka hoʻololi ʻana i ka hoʻopiha ʻana i nā mea inorganic, ka ʻenehana nanocomposite, ka hoʻololi ʻana i ka hui ʻana, a me nā mea ʻē aʻe, e hoʻomaikaʻi i ka hana piha o PBT. ʻO ka hoʻololi ʻana o nā mea PBT e kālele nui ana i nā ʻano o ka ikaika kiʻekiʻe, ka pale ahi kiʻekiʻe, ka warpage haʻahaʻa, ka ua haʻahaʻa a me ka dielectric haʻahaʻa.
Ma keʻano laulā, no ka ʻoihana PBT holoʻokoʻa, nui loa ke koi noi ma nā ʻano like ʻole, a ʻo nā hoʻololi like ʻole e like me ke koi o ka mākeke nā pahuhopu noiʻi a me ka hoʻomohala maʻamau o nā ʻoihana ʻoihana PBT.
