Abstract: ʻO PA612 kahi mea polymer, ʻo ka inoa piha ʻo polyamide 612, ʻike ʻia hoʻi ʻo nylon 612.Ma ke kahua o ka ʻenekinia, hoʻohana nui ʻia ʻo PA612 i ka hana ʻana i nā ʻāpana a me nā ʻāpana i ka automotive, electronics, machinery and other fields.

ʻO PA612 kahi mea polymer, ʻo ka inoa piha he polyamide 612, ʻike ʻia hoʻi ʻo nylon 612. he semi-crystalline engineering plastics, me nā waiwai kino maikaʻi loa a me ke kūpaʻa kemika.
He plastik ʻenekini semi-crystalline me nā waiwai kino maikaʻi a me ke kūpaʻa kemika.Ma ke kahua o ka ʻenekinia, hoʻohana nui ʻia ʻo PA612 i ka hana ʻana i nā ʻāpana a me nā ʻāpana i ka automotive, electronics, machinery and other fields.

Hoʻokumu ʻia ka molecular structure o PA612 e styrene monomer ma o ka polymerization radical manuahi.I ka wā o ke kaʻina hana polymerization, hoʻomaka mua ka styrene monomer i ka hoʻohui radical manuahi e hana i nā radical styrene, a laila e hana hou kēia mau radical i kahi pane ulu kaulahao a lilo i kaulahao polymer.Hāʻawi kēia ʻano molekala iā PA612 i nā waiwai mechanical maikaʻi a me ke kūpaʻa ʻaʻahu.

ʻO ka helu heheʻe o PA612 ka mahana e hoʻololi ai ka mea mai kahi paʻa i kahi wai.No PA612, aia ka helu hehee ma waena o 295-315 degere Celsius.ʻO kahi helu hoʻoheheʻe i kēia pae e hana ai i ka PA612 i kahi plastik ʻenekinia me nā koi wela kaʻina hana kiʻekiʻe.Ma nā noi kūpono, pono e hoʻoholo ʻia ka pae hoʻoheheʻe o PA612 e like me nā kūlana hana a me nā mea hana.

Hoʻopiliʻia ka helu hoʻoheheʻe o PA612 e nāʻano likeʻole, e like me ke kaumaha molekala o ka mea, ke kiʻekiʻe o ka crystallinity, ka nui o ka palaoa a pēlā aku.ʻO ka ʻōlelo maʻamau, ʻoi aku ka kiʻekiʻe o ke kaumaha molekala, ʻoi aku ka kiʻekiʻe o ka helu heheʻe;ʻo ke kiʻekiʻe o ka crystallinity, ʻoi aku ka haʻahaʻa o ka helu heheʻe;ʻo ka liʻiliʻi o ka nui o ka palaoa, ʻoi aku ka kiʻekiʻe o ka helu heheʻe.No laila, hiki ke hoʻomalu ʻia ka pae hoʻoheheʻe o PA612 ma ka hoʻoponopono ʻana i kona kaumaha molekala, crystallinity a me ka nui o ka palaoa a me nā ʻāpana ʻē aʻe.

Ma nā hoʻohana pono, ʻo ka pae hoʻoheheʻe o PA612 he mea nui loa.ʻO ka mea mua, hoʻoholo ia i ka pono o ka mahana wela o PA612.Inā haʻahaʻa loa ka helu hoʻoheheʻe, hiki ke alakaʻi i ka hoʻoheheʻe ʻana a i ʻole ka decomposition o ka mea i ka wā e hana ai;inā kiʻekiʻe loa ka helu hoʻoheheʻe, hiki ke hoʻopilikia i ka pono hana a me ke ola o nā lako.ʻO ka lua, pili pū ka pae hoʻoheheʻe i ke kūpono o PA612 i nā hiʻohiʻona noiʻi like ʻole.No ka laʻana, pono nā ʻāpana i hoʻohana ʻia i nā wahi wela kiʻekiʻe e loaʻa i kahi helu heheʻe kiʻekiʻe e hōʻoia i ko lākou kūpaʻa a me ka hilinaʻi i nā wela kiʻekiʻe.

Ma waho aʻe o kona pae hoʻoheheʻe ʻana, loaʻa iā PA612 nā waiwai kino a me nā mea kemika.Eia kekahi laʻana, uaʻikeʻia e ka ikaika kiʻekiʻe, ka paʻakikī kiʻekiʻe, ka abrasion maikaʻi a me ke kū'ēʻana i ka corrosion.Eia kekahi, PA612 maikaʻi ke kaʻina hana a me ka plasticity, a hiki ke hana ʻia a hana ʻia i nā ʻano like ʻole, e like me ka hoʻoheheʻe ʻana a me ka hoʻoheheʻe extrusion.

I ka hopena, ʻo PA612 kahi mea polymer me ka hana maikaʻi loa, a ʻo kona helu hoʻoheheʻe ʻana mai 295-315 degere Celsius.He mea koʻikoʻi ka mana o kēia pae e hōʻoia i ka hana hoʻoponopono a me ka hopena noi o PA612.Hiki ke loaʻa ka mana maikaʻi o ka pae hoʻoheheʻe o PA612 ma ke koho kūpono ʻana a me ka hoʻoponopono ʻana i nā ʻāpana e like me ke kaumaha molekala, crystallinity a me ka nui o ka palaoa o PA612, i mea e hoʻokō ai i nā pono o nā hiʻohiʻona noiʻi like ʻole.
