Kahua ʻImi
Hoʻohana nui ʻia nā mea hoʻololi Phase (PCM) i ke kūkulu ʻana i ka mahana wela, ka hoʻohana hou ʻana i ka wela a me ka hoʻopau ʻana i ka wela i nā huahana uila ma muli o ko lākou aloha a me ka hoʻomau. Ma waena o nā ʻano like ʻole o nā PCM, nā PCM organik (OPCM) e like me ka polyethylene glycol (PEG) a me ka paraffin wax he kiʻekiʻe ka enthalpy o ka hoʻololi ʻana o ka pae, ʻoi aku ka maikaʻi o ka hoʻololi ʻana o ka pae i ka pae wela, haʻahaʻa corrosiveness, non-toxic a ʻoi aku ka paʻa wela, a no laila ʻoi aku ka maʻamau ma mua o nā ʻano PCM ʻē aʻe. Eia nō naʻe, ʻo ka haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa a me ka manaʻo e kahe ma luna o ka helu heheʻe o nā OPCM he mau pilikia koʻikoʻi i kā lākou noi nui. ʻO ka hopena, ua hana nā hui i nā noiʻi nui e pili ana i kēia mau pilikia.
ʻŌlelo Hoʻolauna
ʻO ka mea i hala koke iho nei, ua hoʻomākaukau ʻia kahi pūʻulu melamine carbonized/reduced graphene oxide coated copper network (MF/rGO/Cu-C) e Prof. Zou Yongjin a me Prof. Sun Lixian hui ma Guilin University of Electronic Science and Technology no ke kūkulu ʻana i nā OPCM multifunctional paʻa. Ua koho ʻia ʻo PEG ma ke ʻano he mea mālama wela a ua hoʻomākaukau ʻia nā OPCM composite (PEG@MF/rGO/Cu-C) ma ka ʻatikala e ka impregnation vacuum. pEG@MF/rGO/Cu-C he kiʻekiʻe hoʻoheheʻe enthalpy (148.3 J g-1) a crystallization enthalpy (143.9 J g-1). Eia kekahi, ua hiki i kona conductivity thermal i 0.4621 W m-1K-1, kahi hoʻomaikaʻi o 463% i hoʻohālikelike ʻia me PEG@MF. ʻO nā OPCM hui pū kekahi e hōʻike i nā waiwai hoʻololi kiʻi-thermal a me electro-thermal hoʻololi maikaʻi a no laila hiki ke loaʻa i nā noi multi-disciplinary.
Nānā Kiʻi
- hoʻouka ʻia ka GO i ka MF(melamin foam) 3D framework e ka impregnation solution e loaʻa ai ka pūnaewele MF/GO; a laila, hoʻopaʻa ʻia ka MF / GO i ke keleawe keleawe a hoʻemi ʻia ka GO i ka manawa like i ka wā o ke kaʻina hana keleawe e loaʻa ai MF / rGO / Cu; a laila, carbonised ka MF / rGO / Cu pūnaewele i ka wela kiʻekiʻe e loaʻa ai MF / rGO / Cu-C; ʻO ka hope, ua hoʻokomo ʻia ka PEG i hoʻokomo ʻia e ka MF/rGO/Cu-C no ka loaʻa ʻana o PEG@MF/MF/rGO/Cu-C composite OPCMs.
- Ua ʻike ʻia ka morphology o ka mea me ka SEM. ʻO ka hana hoʻāʻo ʻana o MF ua loaʻa iā MF/GO, MF/rGO/Cu a me MF/rGO/Cu-C i loaʻa i kahi ʻano 3D porous mesh like. Eia hou, hiki ke ʻike ʻia kahi hoʻouka kūleʻa o nā ʻāpana Cu mai nā kiʻi SEM.
- Hōʻike nā hopena o nā loiloi XRD, FT-IR a me XPS i ka hoʻouka kūleʻa ʻana o nā ʻāpana keleawe a me ka hōʻemi kūleʻa o GO.
- Ua noiʻi ʻia ke ʻano hoʻololi o ka pae o nā OPCM me ka hoʻohana ʻana iā DSC. Ua like nā pihi DSC o nā OPCM hui a pau me ka PEG maʻemaʻe, aia ka piko hoʻoheheʻe a me ka piko crystallisation, e hōʻike ana ʻaʻole i hoʻololi ka hoʻokomo ʻana o ka mea lawe i ka hana crystallisation o PEG. Eia kekahi, ʻo ka hoʻokomo ʻana o rGO a me Cu a me ka mālama carbonization i hoʻomaikaʻi i ka conductivity thermal o ka pūnaewele.
- Loaʻa iā PEG@MF/rGO/Cu-C nā mana hoʻololi kiʻi maikaʻi loa a me ka electrothermal.
Hoʻokipa ʻo SINOYQX i nā leka a me nā kelepona mai nā kulanui, nā ʻoihana noiʻi ʻepekema a me nā ʻoihana ma ka honua. E hāʻawi mākou i nā Laʻana Manuahi no ka noiʻi ʻepekema a me ka hoʻomohala ʻana o nā kulanui nui, nā ʻoihana noiʻi ʻepekema a me nā ʻoihana ma ka honua, ʻoiai ka melamine resin foam (Carbonization Project), e ʻoluʻolu e hoʻokaʻaʻike mai iā mākou ma [email protected] , a i ʻole e leka mai iā mākou: +86-28-8411-1861.
E pili ana iā SINOYQX
He hui kemika nui ʻo SINOYQX e pili ana i ke kaulahao kinoea, hana ʻana i ka urea (AdBlue), melamine, melamine foam, melamine cyanurate (MCA), polyphosphate (MPP), polyvinyl butyral resin (low-polymerization PVB resin), a me nā huahana kemika. ʻO ka mana makahiki o AdBlue he 150,000Litters a me 600,000Tons o Granule; Melamine 50,000Tona; ʻO 200,000M3 ka pahu melamine, ʻo ka Melamine Cyanurate (MCA) he 50,000Tons. A ʻo ka Unuhi (he Equivalent of 3M Thinsulate) he 20,000 Sqm, i kēlā me kēia lā.
