Polybutylene terephthalate(PBT) he semi-crystalline, thermoplastic saturated polyester, maʻamau ka waiu keʻokeʻo, granular solid i ka lumi wela, hoʻohana mau ʻia i ka hana ʻana i nā mea uhi lua thermoplastic cable optical.
He mea koʻikoʻi ka hana ʻana o ka fiber optical second i ka hana ʻana i ka fiber optical. ʻO ka ʻōlelo maʻalahi, hiki ke hoʻonui i ka hiki o ka fiber optical ke pale aku i ke koʻikoʻi longitudinal a me ka radial a hoʻomaʻamaʻa i ka fiber optical post-processing. Ma muli o ka pili kokoke i ka fiber optical, ʻoi aku ka nui o ka hopena i ka hana o ka fiber optical, no laila e koi ʻia ka mea uhi i kahi liʻiliʻi liʻiliʻi liʻiliʻi liʻiliʻi liʻiliʻi, crystallinity kiʻekiʻe ma hope o ka extrusion, kemika maikaʻi a me ke kūpaʻa wela, ʻoluʻolu nā paia o loko a me waho o ka papa uhi, kahi ikaika tensile a me ka modulus Young, a maikaʻi ke kaʻina hana. Hoʻokaʻawale ʻia ka uhi fiber i ʻelua mau ʻāpana: uhi wehe a me ka uhi paʻa. Ma waena o lākou, ʻo ka mea i hoʻohana ʻia i ka uhi ʻana i ka uhi ʻana ʻo ia ka papa pani lua i hoʻokuʻu ʻia i loko o ke kūlana lima lima ma waho o ka fiber uhi mua.
ʻO ka PBT kahi mea lima lima maʻamau me ka hana maikaʻi a me ka hoʻoponopono ʻana i nā waiwai, haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa a me ka hana kiʻekiʻe. Hoʻohana nui ʻia maPBThoʻololi, kiʻi uea PBT, pahu pahu, kiʻi kiʻiʻoniʻoni a me nā kahua ʻē aʻe. Loaʻa i ka PBT nā waiwai mechanical maikaʻi (e like me ke kūpaʻa tensile, ke kūlou ʻana, ka pale ʻana i ka ʻaoʻao), ka pale ʻana i ka solvent maikaʻi, ka pale ʻana i ka aila, ka pale ʻana i ke kino, a me ka fiber paste, ka hoʻopili ʻana i ke kaula a me nā mea ʻē aʻe o ke kaula i kūpono maikaʻi, a he maikaʻi loa ka hana hoʻoheheʻe ʻana, haʻahaʻa haʻahaʻa haʻahaʻa, kumu kūʻai. ʻO kāna mau kūlana hana ʻenehana nui: intrinsic viscosity, yield strength, tensile and bending elastic modulus, impact strength (notch), linear expansion coefficient, wai absorption, hydrolysis resistance a pēlā aku.
Eia nō naʻe, me ka hoʻololi ʻana o ke ʻano o ka fiber cable a me ke kaiapuni hana, ʻoi aku ka nui o nā koi no ka fiber buffer bushing. ʻO ka crystallization kiʻekiʻe, haʻahaʻa haʻahaʻa, haʻahaʻa linear expansion coefficient, kiʻekiʻe paʻakikī, kiʻekiʻe compressive ikaika, ʻoi aku ka maikaʻi o ka kemika kūʻē, ka hana hoʻoponopono maikaʻi, a me nā mea haʻahaʻa haʻahaʻa nā pahuhopu i hahai ʻia e nā mea hana kelepona optical. I kēia manawa, aia nā hemahema i ka noi a me ke kumukūʻai o ka pahu beam i hana ʻia i nā mea PBT, a ua hoʻomaka nā ʻāina ʻē e hoʻohana i nā mea hoʻohui PBT e hoʻololi i nā mea PBT maʻemaʻe, kahi i hoʻokani maikaʻi a me ke kuleana. I kēia manawa, ke hoʻomākaukau ikaika nei kekahi mau ʻoihana kelepona nui, pono nā ʻoihana kelepona i ka ʻenehana hoʻomau, ka noiʻi a me ka hoʻomohala ʻana i nā mea hou.
ʻOiaʻiʻo, ma ka ʻoihana PBT holoʻokoʻa, ʻo nā noi kelepona fiber optic e noho wale i kahi wahi liʻiliʻi o ka mākeke PBT. Wahi a nā kumu ʻoihana, ma ka ʻoihana PBT holoʻokoʻa, ʻo ka hapa nui o ka mākeke e noho nui ʻia e nā ʻāpana ʻelua o ka automotive a me ka mana. Hoʻohana nui ʻia nā mea hoʻohui, nā relays a me nā huahana ʻē aʻe i hana ʻia i nā mea PBT i hoʻololi ʻia i nā mea kaʻa, uila a me nā mea uila, nā lako mīkini a me nā ʻano ʻē aʻe, a hiki i ka PBT ke hoʻohana ʻia ma ke kahua textile, e like me nā bristles o nā pulupulu niho i hana ʻia me PBT. Eia nā hoʻohana maʻamau o PBT ma nā ʻano ʻano like ʻole:
1. ʻO nā māla uila a me nā uila
Hoʻohana nui ʻia nā mea PBT i ka uila a me ka uila, e like me nā kumu mana, nā plugs, nā kumu uila a me nā ʻāpana uila ʻē aʻe. Ma muli o ka maikaʻi o ka hana insulation a me ka pale wela kiʻekiʻe, kūpono loa ia no ka pūpū, bracket, insulation sheet a me nā ʻāpana ʻē aʻe o ka uila a me ka uila. Eia kekahi, hiki ke hoʻohana ʻia nā mea PBT no ka hana ʻana i ka pale LCD pale hope, ka pā TV a pēlā aku.
2.The automotive kahua
Hoʻohana nui ʻia nā mea PBT ma ke kahua kaʻa. Ma muli o kona mau mea maikaʻi o ke kiʻekiʻe wela, corrosion a me ka ʻaʻahu ʻana, hoʻohana nui ʻia nā mea PBT i ka hana ʻana i nā ʻāpana kaʻa, e like me ka intake manifold, ka hale ʻaila ʻaila, ka hale sensor, nā ʻōnaehana brake, etc.
3. ʻO kaʻoihana mīkini
I ka ʻoihana mīkini, hoʻohana pinepine ʻia nā mea PBT no ka hana ʻana i nā mea paahana, nā hoʻololi, nā pihi, a me nā mea ʻē aʻe.
4.ʻO kaʻoihana lāʻau lapaʻau
ʻO nā mea PBT maikaʻi ke kūpaʻa wela kiʻekiʻe a me ke kūpaʻa kemika kiʻekiʻe, kūpono loa ia no ka hana ʻana i nā mea lapaʻau. Eia kekahi laʻana, hiki ke hoʻohanaʻia nā mea PBT no ka hanaʻana i nā hale lāʻau lapaʻau, nā paipu, nā mea hoʻohui, a me nā mea'ē aʻe.
5. ʻO ke kamaʻilio optical
Ma ke kahua o ka kamaʻilio optical, hoʻohana nui ʻia ʻo PBT i ka hana ʻana i nā kaula uila ma ke ʻano he mea lima lima maʻamau. Eia kekahi, hoʻohana nui ʻia nā mea PBT i nā mea optical. Ma muli o kāna mau hiʻohiʻona maikaʻi a me ke kūpaʻa wela kiʻekiʻe, hoʻohana ʻia nā mea PBT no ka hana ʻana i nā mea hoʻohui fiber optical, nā papa hoʻohele optical fiber, a me nā mea ʻē aʻe.
Mai ka hiʻohiʻona o ka ʻoihana holoʻokoʻa, i nā makahiki i hala iho nei, ua kūpaʻa nā ʻoihana pili i ka hoʻomohala ʻana i nā ʻano noiʻi o nā ʻenehana hou a me nā huahana hou, a ua hoʻomohala ʻo PBT i ke ʻano o ka hana kiʻekiʻe, functionalization a me diversification. ʻO ka ikaika tensile resin PBT maʻemaʻe, ka ikaika kulou a me ka modulus bending he haʻahaʻa, ʻaʻole hiki ke hoʻohana nui ʻia i ka ʻoihana ʻoihana, no laila no nā pono o ka ʻoihana ʻoihana, ka ʻoihana ma o ka hoʻololi ʻana e hoʻomaikaʻi i ka hana o PBT. No ka laʻana, hoʻohui ʻia ke aniani aniani i ka PBT - ʻo ka fiber aniani ka maikaʻi o ka hoʻohana ikaika ʻana, ke kaʻina hana hoʻopiha maʻalahi a me ke kumu kūʻai haʻahaʻa. Ma ka hoʻohui ʻana i ka fiber aniani i ka PBT, ua hoʻokō ʻia nā pono kumu o ka resin PBT, a ua hoʻomaikaʻi maikaʻi ʻia ka ikaika tensile, ka ikaika kulou a me ka ikaika notch hopena o nā huahana PBT.
I kēia manawa, ʻo nā ala nui ma ka home a me nā ʻāina ʻē he hoʻololi copolymerization, hoʻololi hoʻopihapiha hoʻopihapiha hoʻopihapiha, ʻenehana nanocomposite, hoʻohuihui hoʻololi, etc., e hoʻomaikaʻi i ka hana piha o PBT. ʻO ka hoʻololi ʻana i nā mea PBT e kālele nui ana i nā ʻano o ka ikaika kiʻekiʻe, ka pale ahi kiʻekiʻe, warpage haʻahaʻa, haʻahaʻa haʻahaʻa a me ka dielectric haʻahaʻa.
Ma keʻano laulā, e pili ana i ka ʻoihana PBT holoʻokoʻa, ʻoi aku ka nui o ka noi noi ma nā ʻano like ʻole, a ʻo nā hoʻololi like ʻole e like me ka makemake o ka mākeke ʻo ia nā pahuhopu noiʻi maʻamau a me ka hoʻomohala ʻana o nā ʻoihana ʻoihana PBT.
