ʻO nā plastik ʻenekinia hana kiʻekiʻe–PPO polyphenylene ether material. ʻO ke kūpaʻa wela maikaʻi loa, nā waiwai uila, ka ikaika kiʻekiʻe a me ke kūpaʻa creep a pēlā aku, hāʻawi i nā mea PPO me nā pono noi i ka automotive., nā lako uila, 5G a me nā kahua ʻē aʻe.
Ma muli o ke kiʻekiʻe melt viscosity a me ka maikaʻi ʻole o ka wai o nā mea PPO, ʻo nā mea PPO i hoʻololi ʻia (MPPO) i kēia manawa ma ka mākeke, a ʻo nā mea i hoʻololi ʻia ʻo PPO nā ʻano hoʻololi koʻikoʻi.
ʻO kēia nā mea maʻamau i hoʻololi ʻia i ka PPO alloy ma ka mākeke, e nānā kākou:
01.PPO/PA mea hao
ʻO ka mea PA (nylon) he mau mea mechanical maikaʻi loa, pale i ka pale, lubrication ponoʻī, hana maʻalahi a me nā ʻano ʻē aʻe, akā ʻoi aku ka nui o ka polar wai kiʻekiʻe, a hoʻololi nui ka nui o ka huahana ma hope o ka lawe ʻana i ka wai.
ʻO ka mea PPO he haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa o ka wai, ke kūpaʻa maikaʻi ʻana, a me ke kūpaʻa creep maikaʻi loa, akā maikaʻi ʻole ka hana. Hiki ke ʻōlelo ʻia ʻo PPO/PA alloy material e hui pū i nā waiwai maikaʻi o nā mea ʻelua. ʻO kēia ʻano mea hoʻoheheʻe ʻia kekahi ʻano o ka alloy me ka hoʻomohala wikiwiki a me nā ʻano ʻē aʻe ma waena o nā alloys PPO. Hoʻohana nui ia no nā ʻāpana kaʻa, e like me nā uhi huila, nā ʻāpana peripheral engine, etc.
Pono e hoʻomaopopo ʻia ʻo ka amorphous PPO a me ka crystalline PA he thermodynamically incompatible, a ʻo kā lākou mea hoʻohui maʻalahi he maʻalahi ke delaminate, loaʻa nā waiwai mechanical maikaʻi ʻole, a he haʻahaʻa ka waiwai kūpono; pono e hana ʻia nā hana kūpono e hoʻomaikaʻi ai i ka hana o nā mea ʻelua. kūpono e hoʻomaikaʻi i kāna hana. ʻO ka hoʻohui ʻana i kahi mea hoʻohālikelike kūpono a me ka hoʻohana ʻana i kahi kaʻina hana kūpono hiki ke hoʻomaikaʻi maikaʻi i ka hoʻohālikelike ʻana o PPO a me PA.
02.PPO/HIPS mea hao
He kūpono maikaʻi nā mea PPO me nā mea polystyrene, a hiki ke hoʻohui ʻia i kēlā me kēia ʻāpana me ka ʻole o ka hōʻemi ʻana i nā waiwai mechanical.
ʻO ka hoʻohui ʻana o HIPS i ka mea PPO e hoʻonui i ka ikaika hopena notched. ʻO ka maʻamau, i mea e hoʻomaikaʻi hou ai i ka ikaika o ka hopena o ka ʻōnaehana a hoʻomaikaʻi i ka hana holoʻokoʻa, hoʻohui pinepine ʻia nā elastomers e like me nā mea hoʻololi paʻakikī, e like me SBS, SEBS, etc.
Eia kekahi, ʻo ka PPO ponoʻī he ʻano polymer e pale i ka lapalapa, maʻalahi e hana i ke kalapona, a loaʻa iā ia nā mea hoʻopau ponoʻī. Ke hoʻohālikelike ʻia me ka HIPS maʻemaʻe, hiki ke hoʻomaikaʻi maikaʻi ʻia nā waiwai pale ahi o PPO/HIPS alloys. Me ka hoʻonui ʻana i ka nui o ka PPO, ua emi iki ka hoʻoheheʻe ʻana a me ka puhipuhi ʻana o ka polymer alloy i ka wā o ka hoʻopau ʻana, a ua piʻi mālie ke kiʻekiʻe o ka puhi ahi.
Nā kahua noi nui: nā ʻāpana pale wela o nā kaʻa, nā mea uila a me nā mīkini uila, nā ʻāpana o nā lako sterilization mahu, etc.
03.PPO/PP mea hao
ʻO ke kumukūʻai a me ka hana ʻana o ka PPO / PP alloys ma waena o nā mea ʻenehana ʻenehana, e like me PA, ABS, lōʻihi aniani fiber PP, hoʻololi ʻia ʻo PET a me PBT, a me nā mea ʻē aʻe, a ua loaʻa iā lākou kahi kiʻekiʻe kiʻekiʻe o ka rigidity, ka paʻakikī, ka pale wela a kumukūʻai. kaulike maikaʻi. Aia nā noi i loko o ka ʻoihana kaʻa, ka mana, nā pahu mea hana, nā pā mālama meaʻai, nā ʻāpana lawe wai (pump houses), etc.
Ua makemake ʻia nā ʻaila e nā mea hana kaʻa ma muli o ko lākou kūlike me nā plastics ʻē aʻe i ka manawa o ka hana hou ʻana, ʻo ia hoʻi, hiki ke hoʻohui ʻia a hana hou ʻia me nā plastics-based PP ʻē aʻe a i ʻole ke ʻano o nā plastics-based polystyrene.
04.PPO/PBT mea huila
ʻOiai he mau waiwai piha ka PBT, aia nō nā pilikia e like me ka hydrolysis maʻalahi, hiki ʻole ke kū i ka wai wela no ka manawa lōʻihi, nā huahana prone i anisotropy, hoʻoheheʻe ʻia a me ka warpage, etc. nā hemahema hana.
Wahi a ka noiʻi ʻana i nā mea hoʻopili pili, ʻoi aku ka maikaʻi o ka haʻahaʻa haʻahaʻa haʻahaʻa PPO mea no ka hui ʻana me ka PBT material alloy, akā pono ia i ka compatibilizer no ka hoʻohui.
Hoʻohana maʻamau e hana i nā mea uila, nā ʻāpana uila a pēlā aku.
05. ʻO nā mea hoʻohui PPO/ABS
Aia nā mea ABS i ka hoʻolālā PS, kahi kūpono kūpono me PPO a hiki ke hoʻopili pololei ʻia. Hiki i nā mea ABS ke hoʻomaikaʻi maikaʻi i ka ikaika o ka hopena o PPO, hoʻomaikaʻi i ke koʻikoʻi o ke kaumaha, a hāʻawi i ka PPO electroplatability, ʻoiai e mālama ana i nā waiwai piha o PPO.
ʻOi aku ka haʻahaʻa o ke kumukūʻai o ABS ma mua o ka PPO, a ua nui ka waiwai o ka mākeke. Ma muli o ka like like o nā mea ʻelua a he maʻalahi ke kaʻina hana hoʻohui, hiki ke ʻōlelo ʻia he mea hoʻohui PPO maʻamau, kūpono ia no nā ʻāpana kaʻa, nā lako pale electromagnetic, nā lako keʻena, nā mīkini keʻena a me nā paipu wili, etc.
