ʻO nā plastik ʻenekinia PBT, (polybutylene terephthalate), maikaʻi loa ka hana piha, haʻahaʻa ke kumu kūʻai, a maikaʻi hoʻi ka hoʻoheheʻe ʻana.I nā mea uila, nā mea uila, nā mea mīkini, nā kaʻa a me nā mea hana pololei a me nā māla ʻē aʻe, ua hoʻohana nui ʻia.
Nā hiʻohiʻona o ka PBT i hoʻololi ʻia
(1) ʻO nā waiwai mechanical maikaʻi loa, ka ikaika kiʻekiʻe a me ke kūpaʻa luhi, ke kūpaʻa maikaʻi a me ke kolo liʻiliʻi.Ma lalo o nā kūlana wela kiʻekiʻe, hoʻololi iki ka hana.
(2) Hiki ke hoʻokō i nā koi o ka papa UL94 V-0 i hoʻohui ʻia a me ke ʻano o ka hoʻopaʻa ʻana i ka lapalapa ahi.Ua hoʻohana nui ʻia i ka uila a me ka ʻoihana uila.
(3) Heat resistance, aging resistance, organic solvent resistance.Hoʻonui ʻia ka helu ʻana o ka mahana o ka UL ma waena o 120 ° C a 140 ° C, a loaʻa iā lākou a pau ka ʻelemakule maikaʻi o waho.
(4) Hana hana maikaʻi.ʻO ka maʻalahi i ka hana lua a me ka hoʻoheheʻe ʻana, me ke kōkua o nā mea hana maʻamau hiki ke hoʻoheheʻe extrusion a i ʻole ka hoʻoheheʻe injection;Loaʻa iā ia ka wikiwiki crystallization a me ka fluidity maikaʻi, a ʻoi aku ka haʻahaʻa o ka mahana o ka mold
Kuhikuhi hoʻololi o PBT
1. Hoʻololi hoʻonui
I ka PBT hoʻohui aniani puluniu, aniani puluniu a me ka PBT resin hoʻopaʻa ikaika mea maikaʻi, i loko o ka PBT resin hoʻohui i kekahi nui o ke aniani puluniu,ʻaʻole wale hiki ke malama i ka PBT resin kemika kū'ē, ka hana a me nā mea mua pono, akā, hiki ke loaʻa i kahi. ʻoi aku ka nui o ka hoʻonui ʻana i kāna mau waiwai mechanical, a lanakila i ka naʻau notch resin PBT.
2. Hoʻololi i ka lapalapa ahi
ʻO ka PBT kahi polyester aromatic crystalline, me ka ʻole o ka lapalapa ahi, ʻo UL94HB kona pale ahi, aia wale nō ma hope o ka hoʻohui ʻana o ka lapalapa ahi, hiki ke hiki i UL94V0.
Hoʻohana mau ʻia nā mea pale ahi i ka bromide, Sb2O3, phosphide a me ka chloride halogen flame retardants, e like me ka hapa nui he ʻumi bromine biphenyl ether, ʻo ia ka PBT nui, ka lapalapa ahi, akā ma muli o ka mālama ʻana i ke kaiapuni, ua pāpā lōʻihi nā ʻāina ʻEulopa i ka hoʻohana. Ke ʻimi nei nā ʻaoʻao i ka mea pani, akā ʻaʻohe pono hana i ʻoi aku ma mua o ka ʻumi bromine biphenyl ether pani.
3. Hoʻololi i ka hui ʻana i nā mea hao
ʻO ke kumu nui o ka hui ʻana o PBT me nā polymers ʻē aʻe e hoʻomaikaʻi i ka ikaika o ka hopena notched, hoʻomaikaʻi i ka deformation warping i hoʻokumu ʻia e ka hoʻoheheʻe ʻana, a hoʻomaikaʻi i ka pale wela.
Hoʻohana nui ʻia ka hui ʻana e hoʻololi iā ia ma ka home a ma waho.ʻO nā polymers i hoʻololi ʻia i hoʻohana ʻia no ka hui ʻana o PBT ʻo PC, PET, etc.ʻOkoʻa ka māhele o ka fiber aniani, a ʻokoʻa hoʻi kāna kahua noi.
Nā noi nui o nā mea PBT
1. Nā lako uila
ʻAʻohe fuse breaker, electromagnetic switch, drive back transformer, home appliance handle, connector, etc. PBT is usually added 30% glass fiber mixing as connector, PBT is much used because of mechanical properties, solvent resistance, forming processing and low price.
2. Heat dissipation fan
Hoʻohana nui ʻia ke aniani fiber i hoʻoikaika ʻia i ka peʻa hoʻoheheʻe wela, ua hoʻokomo ʻia ka mea hoʻoheheʻe wela i ka mīkini no ka manawa lōʻihi e kōkua i ka hoʻoheheʻe ʻana i ka wela, ʻo nā ʻano kino o nā koi plastic he pale wela, flammability, insulation a me ka ikaika mechanical. ʻO ka mea maʻamau i ke ʻano o 30% fiber i hoʻohana ʻia e like me ka peʻahi hoʻoheheʻe wela ma waho o ke kiʻi a me ke kumu wili puʻupuʻu fan.
3. Nā mea uila
Hoʻohana pū ʻia ʻo PBT i hoʻoikaika ʻia i ke aniani fiber ma ke ʻano he transformer, relay i loko o ka coil shaft, maʻamau PBT me ka fiber 30% injection forming.ʻO nā waiwai kino i makemakeʻia o ka'āpana coil e komo pū me ka insulation, ka wela wela, ka pale kuʻi, ka wai a me ka ikaika, a me nā mea'ē aʻe.
4. Automotiveʻāpana
A. Ma waho o waho: ka nui o ke kaʻa kaʻa (PC/PBT), ka lima o ka puka, ka lattice kihi, ka uhi ʻana o ka puka wela engine, ka pahu puka makani kaʻa, fender, uhi uwea, uhi huila kaʻa hoʻoili pahu pahu, etc.
B. Nā ʻāpana o loko: ʻo ka nui o ka endoscope brace, wiper bracket a me ka ʻōnaehana ʻōnaehana hoʻokele;
C, ʻāpana uila kaʻa kaʻa: kaʻa kaʻa ignition coil twist tube a me nā mea hoʻohui uila, etc.
I ka manawa like, hiki ke hoʻopili ʻia i ka pū kī o nā kaʻa ikaika hou.
5. Mea hana mīkini
Hoʻohana nui ʻia nā mea PBT i ka pahu wikiō leo leo kāʻei kāʻei, uhi kamepiula, mercury ipukukui, uhi hao, ʻāpana mīkini paʻi a me ka nui o nā mea hana, CAM, pihi, hale kiaʻi uila, nā ʻāpana kamera (me ka wela, nā koi retardant ahi. )
Nā māka nui o SIKOPOLYMERS o PBT a me kā lākou wehewehe ʻana, penei:
