Na Andy mai ka hale hana Baiyear
Hoʻopuka ʻia ma Nowemapa 2, 2022
Eia ke kikowaena nūhou o ka ʻoihana hoʻoheheʻe injection o Baiyear.Ma hope aʻe, e puʻunaue ʻo Baiyear i ke kaʻina hana hoʻoheheʻe i loko o kekahi mau ʻatikala e hoʻolauna i ka nānā ʻana i nā mea maka o ke kaʻina hana hoʻoheheʻe ʻia, no ka mea he nui loa nā ʻike.A laila ʻo ka ʻatikala ʻeono.
(14).PPO (polyphenylene ether)
1. Hana o PPO
ʻO ka polyphenylene oxide ka poly-2,6-dimethyl-1,4-phenylene oxide, i ʻike ʻia he polyphenylene oxide, inoa Pelekane ʻo Polyphenyleneoxiole (i kapa ʻia ʻo PPO), hoʻololi ʻia ka polyphenylene ether me ka polystyrene a i ʻole nā polymers ʻē aʻe.ʻO ka polyphenylene ether, i kapa ʻia ʻo MPPO.
ʻO ka PPO (NORLY) he plastic engineering me nā waiwai piha maikaʻi loa.ʻOi aku ka paʻakikī ma mua o PA, POM a me PC, ikaika mechanical kiʻekiʻe, rigidity maikaʻi, kūpaʻa wela maikaʻi (ʻo 126 ℃ ka wela wela), a me ke kūpaʻa kiʻekiʻe (shrinkage wela).ka helu o 0.6%), haʻahaʻa wai absorption (emi ma lalo o 0.1%).ʻO ka hemahema ʻo ia ʻaʻole paʻa i nā kukui ultraviolet, kiʻekiʻe ke kumukūʻai, a liʻiliʻi ka dosage.
ʻAʻole ʻawaʻawa ʻo PPO, ʻikea, haʻahaʻa haʻahaʻa haʻahaʻa, a loaʻa iā ia ka ikaika mechanical maikaʻi loa, ke kūpaʻa hoʻomaha hoʻomaha, ke kūpaʻa ʻana, ka pale wela, ka pale wai, a me ke kū ʻana o ka mahu wai.ʻO nā waiwai uila maikaʻi ma kahi ākea o ka mahana a me ka hoʻololi pinepine ʻana, ʻaʻohe hydrolysis, liʻiliʻi liʻiliʻi liʻiliʻi, pale ahi a me ka hoʻopau ʻana iā ia iho, kūʻē maikaʻi ʻole i nā waikawa inorganic, alkalis, hydrocarbons aromatic, halogenated hydrocarbons, aila, etc., maʻalahi e pehu A i ʻole. ʻO ke kaumaha o ke kaumaha, ʻo ka hemahema nui ka wai hoʻoheheʻe maikaʻi ʻole, ka hana paʻakikī a me ka hoʻokumu ʻana, ʻo ka hapa nui o nā noi kūpono he MPPO (PPO blends a i ʻole alloys), e like me ka hoʻololi ʻana o PS o PPO, hiki ke hoʻomaikaʻi maikaʻi i ka hana hana, hoʻomaikaʻi i ke kūpaʻa ʻana i ke kaumaha a me ka hopena. kū'ē Hana, ho'ēmi kumu kūʻai, hoʻemi iki wale i ka pale wela a me ka'ōlinolino.
ʻO nā polymers i hoʻololi ʻia he PS (me HIPS), PA, PTFE, PBT, PPS a me nā elastomers like ʻole, polysiloxane, PS hoʻololi ʻia ʻo PPO paraffin, ʻo ka huahana nui loa, ʻo MPPO ka mea hoʻohana maʻamau i hoʻohana ʻia.ʻO nā ʻano MPPO nui loa he PPO/PS, PPO/PA/elastomers a me PPO/PBT elastomer alloys.
2. Kaʻina hana o PPO:
Loaʻa i ka PPO ka viscosity melt kiʻekiʻe, ka wai maikaʻi ʻole, a me nā kūlana hana kiʻekiʻe.Ma mua o ka hana ʻana, pono e hoʻomaloʻo ʻia ma kahi mahana o 100-120 ° C no 1-2 mau hola, ʻo ka mahana hoʻoheheʻe ʻia ʻo 270-320 ° C, a ʻoi aku ka maikaʻi o ka mālama ʻana i ka mahana ma 75-95 ° C.hana ʻana.Ma ke kaʻina hana o kēia plastic beer plastic, maʻalahi ka hana ʻana i ke ʻano o ka jet flow (serpentine pattern) i mua o ka nozzle, a ʻoi aku ka nui o ke kahawai kahe o ka nozzle.
ʻO nā mānoanoa liʻiliʻi mai ka 0.060 a i ka 0.125 iniha no nā hoʻoheheʻe maʻamau a me 0.125 a i ka 0.250 iniha no nā huʻa hana, a me nā pae flammability mai UL94 HB a VO.
3.Typical noi laha:
Hiki ke hana ʻia ʻo PPO a me MPPO e nā ʻano hana like ʻole e like me ka injection molding, extrusion, blow molding, molding, foaming and electroplating, vacuum coating, mīkini paʻi mīkini, etc., ma muli o ke kiʻekiʻe melt viscosity a me ke kiʻekiʻe o ka mahana wela.
Hoʻohana nui ʻia ʻo PPO a me MPPO i nā lako uila, nā kaʻa, nā lako hale, nā lako keʻena a me nā mīkini ʻenehana, a me nā mea ʻē aʻe, me ka hoʻohana ʻana i ka MPPO no ka pale ʻana i ka wela, ka hopena hopena, ke kūpaʻa dimensional, ka pale ʻana, a me ka pale ʻana i ka peeling;
Hiki ke pena a me nā waiwai uila: hoʻohana ʻia no ka hana ʻana i nā dashboards kaʻa, nā pahu radiator, nā grilles leo, nā consoles, nā pahu fuse, nā pahu relay, nā mea hoʻohui, nā uhi huila;hoʻohana nui ʻia i ka ʻoihana uila a me ka uila e hana i nā mea hoʻohui, nā wili wili ʻana i nā Spools, nā relays hoʻololi, nā mea hoʻokani pila, nā hōʻike uila nui, nā capacitors hoʻololi, nā lako pākaukau, nā microphones a me nā mea ʻē aʻe.
Hoʻohana ʻia nā mea hana hale no nā kīwī, nā pahu kiʻiʻoniʻoni, nā lipine wikiō, nā mea hoʻopaʻa leo, nā ea ea, nā mea wela, nā kuke laiki a me nā ʻāpana ʻē aʻe.Hiki ke hoʻohana ʻia e like me nā ʻāpana o waho a me nā ʻāpana no nā kope kope, nā ʻōnaehana kamepiula, nā mea paʻi, nā mīkini fax, etc. mea ʻokiʻoki, sterilizer a me nā ʻāpana lāʻau lapaʻau ʻē aʻe.
Hiki ke hoʻohana ʻia ka hoʻoheheʻe nui ʻana no nā ʻāpana kaʻa nui e like me nā mea hao, bumpers, a me ka hoʻoheheʻe haʻahaʻa.He kūpono ia no ka hana ʻana i nā huahana nui me ka rigidity kiʻekiʻe, ke kūpaʻa dimensional, ka hoʻoheheʻe ʻana i ke kani maikaʻi loa, a me nā hale paʻakikī o loko, e like me nā ʻano ʻē aʻe o ka mīkini, nā kumu, nā loko ʻO ka bracket a me ka hoʻolālā he kūʻokoʻa nui, a māmā ka huahana.
(15).PBT polybutylene terephthalate
1. Hana o PBT:
ʻO PBT kekahi o nā thermoplastics ʻenehana ikaika loa.He mea semi-crystalline me ke kūpaʻa kemika maikaʻi loa, ka ikaika mechanical, nā waiwai insulating uila a me ke kūpaʻa wela.He kūpaʻa maikaʻi kēia mau mea i kahi ākea o nā kūlana kaiapuni, a he nāwaliwali loa ka PBT i nā waiwai hygroscopic.ʻO ka ikaika tensile o PBT unreinforced ʻo 50MPa, a ʻo ka ikaika tensile o ke aniani additive type PBT he 170MPa.ʻO ka nui o ka mea hoʻohui aniani e lilo i mea palupalu.
PBT;He wikiwiki loa ka crystallization, kahi e hoʻohuli ai i ka deformation ma muli o ke anuanu ʻole.No nā mea me nā mea hoʻohui aniani, hiki ke hoʻemi ʻia ka hoʻohaʻahaʻa ʻana i ke kaʻina hana, akā ʻo ka hoʻohaʻahaʻa ʻana i ke kuhikuhi perpendicular i ke kaʻina hana e like me nā mea maʻamau.
ʻO ka nui o ka emi ʻana o nā mea ma waena o 1.5% a me 2.8%.ʻO nā mea i loaʻa he 30% nā mea hoʻohui aniani e emi iho ma waena o 0.3% a me 1.6%.He haʻahaʻa ka helu heheʻe (225% ℃) a me ka mahana wela deformation kiʻekiʻe ma mua o ka mea PET.ʻO ka mahana hoʻonāwaliwali o Vicat ma kahi o 170°C.Aia ka mahana hoʻololi aniani (glass trasitiotemperature) ma waena o 22°C a me 43°C.
Ma muli o ke kiʻekiʻe o ka crystallization rate o PBT, haʻahaʻa loa kona viscosity, a haʻahaʻa haʻahaʻa ka manawa pōʻai o nā ʻāpana plastic.
2. Kaʻina hana o PBT:
Hoʻomaloʻo: He mea nui ka hoʻomaloʻo ʻana ma mua o ka hana ʻana.ʻO nā kūlana maloʻo i manaʻo ʻia he 120C no 6 ~ 8 hola, a i ʻole 150C no 2 ~ 4 mau hola.
Pono ka haʻahaʻa haʻahaʻa ma lalo o 0.03%.Inā hoʻomaloʻo me kahi desiccator hygroscopic, ʻo nā kūlana i ʻōlelo ʻia he 150 ° C no 2.5 mau hola.ʻO ka mahana hana he 225 ~ 275 ℃, a ʻo ka mahana i manaʻo ʻia he 250 ℃.No nā mea i hoʻopaʻa ʻole ʻia, ʻo ka mahana o ka mold he 40 ~ 60 ℃.Pono e hoʻolālā maikaʻi ʻia ke kahawai hoʻoluʻu o ka ʻōpala e hōʻemi i ka piko o ka ʻāpana plastik.Pono e wikiwiki ka hoʻopau ʻana i ka wela.
ʻO ke anawaena i manaʻo ʻia o ke kahawai hoʻoheheʻe ʻia he 12mm.He haʻahaʻa ka paʻi ʻana (a hiki i 1500bar), a ʻo ka wikiwiki o ka injection e like me ka wikiwiki (no ka mea, paʻa koke ka PBT).Holo a me ka puka: Manaʻo ʻia e hoʻohana i ka mea holo pōʻai e hoʻonui i ka hoʻoili ʻana o ke kaomi (ʻike ʻike: ke anawaena o ka runner = mānoanoa ʻāpana plastik + 1.5mm).
Hiki ke hoʻohana ʻia nā ʻano puka like ʻole.Hiki ke hoʻohana ʻia nā mea holo wela, akā pono e mālama ʻia e pale i ka leakage a me ka hōʻino ʻana o ka mea.Pono ke anawaena o ka puka ma waena o 0.8~1.0*t, kahi t ka mānoanoa o ka ʻāpana plastik.Inā he puka i loko o ka wai, ua ʻōlelo ʻia ke anawaena haʻahaʻa o 0.75mm.
3.Typical noi laha:
nā mea hana hale (nā lau hoʻoponopono meaʻai, nā mea hoʻomaʻemaʻe hoʻomaʻemaʻe, nā pā uila, nā hale hoʻomaloʻo lauoho, nā ipu kofe, a me nā mea ʻē aʻe), nā mea uila (nā kī, nā hale kaʻa, nā pahu fuse, nā kī kī kamepiula, a me nā mea ʻē aʻe). nā panela kino, nā uhi huila, nā ʻāpana puka a me nā puka makani, etc.
Nui ka ʻike i hoʻokomo ʻia ma kēia wahi.No ka ʻike hou aʻe, e hōʻano hou ʻo Baiyear iā ia i ka hiki.E hoʻomaikaʻi mau mākou i nā mea plastik, ka hoʻoheheʻe ʻia ʻana, ka hoʻokomo ʻana i nā mea hana hoʻoheheʻe, ka hoʻolālā ʻana, ke kālai ʻia ʻana, ka hoʻokomo ʻana i nā lako hana, ka hoʻoili ʻana i ka pepa, ka nūhou ʻike e pili ana i ka hana pahu hāʻawi, ka hana pahu metala, ka hoʻokomo ʻana i nā lako hana metala, wai wai. ʻO ka pahu hui, ka uhi puka makani wai, a me nā mea'ē aʻe. Inā makemakeʻoe i kaʻike i luna nei, hiki iāʻoe ke hoʻokaʻaʻike mai iaʻu i kēlā me kēia manawa, e hauʻoli wau e lawelawe iāʻoe a e kali i kou hikiʻana mai.
