ʻO Rotomolding ke ʻano o ka hana ʻana i nā huahana plastic hollow i hoʻohana ʻia i ko mākou ola i kēlā me kēia lā, a ʻo ia kekahi o nā ʻoihana ulu wikiwiki loa i ka ʻoihana plastik i nā makahiki i hala.
ʻAʻole like me nā ʻano hana ʻē aʻe, ʻo ka hoʻomehana ʻana, ka hoʻoheheʻe ʻana, ka hoʻoheheʻe ʻana, a me ka hoʻoluʻu ʻana o ka hoʻoheheʻe ʻana o ka rotational e hana ʻia ma hope o ka hoʻokomo ʻia ʻana o ka polymer i loko o ka mold, ʻo ia hoʻi, ʻaʻohe koi o waho e koi ʻia i ka wā o ke kaʻina hana.
Hoʻohana pinepine ʻia ka mold me ka alumini cast, CNC machined alumini, a i ʻole ke kila.Ke hoʻohālikelike ʻia me nā ʻōpala i hoʻohana ʻia i nā ʻano hana ʻē aʻe (e like me ka injection a i ʻole ka puhi ʻana i ka puhi ʻana), ʻaʻole maʻalahi ke kumukūʻai.
He mea maʻalahi ke kaʻina hana hoʻoheheʻe rotational, akā he mea maʻalahi loa.ʻO ka mua, hoʻopiha ʻia ka lua me ka polymer pauka (e kūkākūkā ʻia ma ka ʻāpana aʻe).
Hoʻomaʻamaʻa ʻia ka umu a ma kahi o 300°C (572°F) ʻoiai e hoʻololi ʻia ka ʻōpala ma nā koʻi ʻelua e puʻunaue like i ka polymer.ʻO ke kumu kumu, ʻo nā ʻāpana pauka (ma kahi o 150-500 microns) e hui pū ʻia e hana i kahi huahana hoʻopau mau.ʻO ka hopena hope o ka huahana e hilinaʻi nui ʻia i ka nui o nā ʻāpana pauda.
ʻO ka hope, hoʻomaʻalili ʻia ka ʻōpala a lawe ʻia ka huahana no ka hoʻopau ʻana.Hiki ke hoʻololi ʻia ka manawa pōʻai o ke kaʻina hana rotomolding maʻamau mai 20 mau minuke a i 1 hola, ma muli o ka nui a me ka paʻakikī o ka huahana.
Ma muli o ka huahana hope i makemake ʻia, hiki ke hoʻohana ʻia nā ʻano polymers plastic i ka rotomolding.
ʻO ka polyethylene (PE) kekahi i hoʻohana maʻamau ʻia no ka mea hiki iā ia ke pale i nā wela kiʻekiʻe no ka manawa lōʻihi a ʻoi aku ka maʻalahi.Eia kekahi, hiki ke maʻalahi ka PE haʻahaʻa haʻahaʻa a kū i ka haki.
Hoʻohana maʻamau ka poʻe moldmakers i ka ethylene-butyl acrylate no ka mea he kūʻē a me ka ikaika o kēia mea i nā wela haʻahaʻa.E like me ka hapa nui o nā thermoplastics, loaʻa iā ia ka pono o ka maʻalahi o ka hana hou
ʻOiai ʻo ka polypropylene he plastic i hoʻohana nui ʻia, ʻaʻole ia ka mea i koho mua ʻia e ka nui o nā mea hana.ʻO ke kumu, lilo kēia mea i mea palupalu ma kahi kokoke i ka mahana o ka lumi, no laila he liʻiliʻi ka manawa o nā mea hana e hana i ka huahana.
Nui nā huahana o kēlā me kēia lā i hana ʻia me ka hoʻohana ʻana i nā ʻano hoʻoheheʻe rotational, e like me nā huahana maʻamau.Aia kekahi mau laʻana ma lalo nei.
ʻO ka Rotomolding kahi hana hoʻoheheʻe maikaʻi loa, e hiki ai i nā mea hana ke hana i nā huahana lōʻihi loa me ka liʻiliʻi o ka hoʻolālā ʻana, akā e hana pū kekahi ma ke ʻano pili i ke kaiapuni me ke kumu kūʻai haʻahaʻa.Eia kekahi, hiki ke hana maʻalahi i nā huahana nui ma ke ʻano waiwai, me ka liʻiliʻi o nā mea i pau.
Hiki ke hoʻonohonoho koke ʻia ʻo Rotomolding, hiki ke hoʻokō i nā pono i ʻike ʻole ʻia a hana i nā ʻāpana liʻiliʻi.Kōkua ia i ka hōʻemi ʻana i ka waihona a me ka hoʻihoʻi ʻana o ka waihona waiwai, e hoʻohālikelike ʻia i ka hana ʻana, fiberglass, injection, vacuum, a i ʻole nā hana hoʻoheheʻe puhi.
ʻO ka versatility o ka rotational molding kekahi o kāna mau pono nui.Hiki iā ia ke hana i nā huahana me ka ʻole o nā laina weld polymer, me nā papa he nui a me nā ʻano like ʻole, nā kala a me ka hoʻopau ʻana i ka ʻili.ʻAʻole hiki i ka Rotomolding ke hoʻokomo wale i nā mea hoʻokomo, akā pū kekahi logos, grooves, nozzles, bosses a me nā hana hou aku e hoʻokō i nā koi koi a me nā koi ʻenehana.Eia kekahi, hiki i ka hoʻohana ʻana i kēia ʻano hana ke hana i nā ʻano huahana like ʻole ma ka mīkini hoʻokahi.
Ua puka 'o Gary mai ke Kulanui o Manchester me ke kēkelē hanohano o ka papa mua ma ka geochemistry a me ke kēkelē laepua ma ka geosciences.Ma hope o ka hana ʻana i ka ʻoihana mining Australia, ua hoʻoholo ʻo Gary e kau i kāna mau kāmaʻa geology a hoʻomaka e kākau.Ke hoʻomohala ʻole ʻo ia i ka ʻike kumuhana a me ka ʻike, hiki iā ʻoe ke ʻike maʻamau iā Gary e pāʻani ana i kāna kīkā aloha, a i ʻole ke nānā ʻana iā Aston Villa Football Club e lanakila a eo.

Ma kēia nīnauele, ua ʻōlelo ʻo Dr.-Ing.Ua hāʻawi ʻo Tobias Gustmann i nā ʻike kūpono e pili ana i nā pilikia o ka noiʻi hana hoʻohui metala.
Ua kūkākūkā ʻo AZoM lāua ʻo Professor Guihua Yu o ke Kulanui o Texas ma Austin i kahi ʻano hou o ka pepa hydrogel e hiki ke hoʻololi koke i ka wai haumia i wai inu maʻemaʻe.He hopena nui paha kēia kaʻina hana hou i ka hoʻopau ʻana i ka nele o ka wai honua.
Ma kēia nīnauele, ua kamaʻilio ʻo AZoM lāua ʻo Jurgen Schawe mai METTLER TOLEDO e pili ana i ka calorimetry chip scan wikiwiki a me kāna mau noi like ʻole.
Hiki i ka MicroProf® DI ke nānā aku i nā mea hana no nā noi semiconductor ke nānā i nā wafers i kūkulu ʻia a i hoʻonohonoho ʻole ʻia i loko o ke kaʻina hana.
ʻO StructureScan Mini XT ka mea hana maikaʻi loa no ka nānā ʻana;hiki iā ia ke hoʻomaopopo pololei a me ka wikiwiki i ka hohonu a me ke kūlana o nā mea metala a me nā mea ʻole i loko o ke kaʻa.
ʻO Miniflex XpC he X-ray diffractometer (XRD) i hoʻolālā ʻia no ka hoʻomalu maikaʻi ʻana i nā mea kanu sima a me nā hana ʻē aʻe e koi ai i ka mana kaʻina hana pūnaewele (e like me nā lāʻau lapaʻau a me nā pā).
Ua noiʻi ʻia ka noiʻi hou ma China Physics Letters i ka superconductivity a me ka hoʻopaʻa haʻahaʻa haʻahaʻa i nā mea papa hoʻokahi i ulu ʻia ma nā substrates graphene.
E ʻimi kēia ʻatikala i kahi ala hou e hiki ai ke hoʻolālā i nā nanomaterials me ka pololei o lalo o 10 nm.
Hōʻike kēia ʻatikala e pili ana i ka hoʻomākaukau ʻana i nā BCNT synthetic e ka catalytic thermal chemical vapor deposition (CVD), e alakaʻi ana i ka hoʻoili wikiwiki ʻana ma waena o ka electrode a me ka electrolyte.
