ʻO nā hiʻohiʻona kumu a me ka hoʻolauna ʻana o ka Polyamide Pa6

ʻO ka hoʻokomoʻana i ka polyamid pa6

ʻO ka polyamide, i kapa ʻia ʻo polyamide pa no ka pōkole, ʻike maʻamau ʻia ʻo ka nylon.He ʻano ʻano plastic thermoplastic crystalline i hana ʻia e ka polymerization o nā amine binary a me ka diacid a i ʻole lactam.Nui nā ʻano PA, e like me ka helu o nā ʻātoma kalapona i loko o ka monomer i komo i ka hopena polymerization, a hiki ke hana ʻia nā ʻano like ʻole o PA me nā hana like ʻole, e like me PA6, PA66, PA612, PA1010, PA11, PA12, PA46 , PA9, PA1212, etc. PA6 a me PA66 ka nui o ka hoohana, no ka 90% o ka huina hoonui.

Nā waiwai nui o ka polyamid pa6

ʻO ka polyamid pa6 ka polarity, ʻaʻohe mea ʻawaʻawa, ʻono a maʻalahi hoʻi ke kala ʻia; ʻAno Crystalline (50 a 60%), translucent milky keʻokeʻo a i ʻole granule melemele māmā; ʻO nā wai Newtonian (nā wai Newtonian e pili ana i nā wai kahi i kūlike ai ke kaumaha me ka. ʻO ka mānoanoa o ke koʻikoʻi); 1.02 a i 1.20g/cm³; ʻO ka lawe ʻana i ka wai kiʻekiʻe, ka hopena o ka hydrolysis ma 230 degere Celsius; ʻO ka lawe ʻana i ka wai PA46 > PA6 > PA66 > PA1010 > PA11 > PA12 > PA1212; Ka nui o ka emi ʻana o ka molding.PP, PE > PA > PS, ABS.ʻO ka waiwai pale waena a me ka pale ikaika i ka ea.

ʻO nā mea mechanical o ka polyamid pa6

ʻO nā mea mechanical o ka polyamid pa6 e pili ana i ka crystallinity: ʻO ke kiʻekiʻe o ka crystallinity, ʻoi aku ka kiʻekiʻe o ka ikaika a ʻoi aku ka ikaika o ka rigidity.Ma keʻano o ka ikaika, PC> PA66> PA6> POM> ABS. Hoʻopilikia nuiʻia ka ikaika e ka hygroscopicity, ke kiʻekiʻe o ka mahana, ke kiʻekiʻe o ka hygroscopicity, ka haʻahaʻa o ka ikaika tensile a me nā waiwai'ē aʻe.

Hoʻopilikia nui ʻia ka paʻakikī hopena e ka hana hygroscopic.Me ka piʻi ʻana o ka mahana, piʻi ka hoʻoheheʻe wai a piʻi ka paʻakikī.(ʻO ka mea maʻamau, ʻilihune ka paʻakikī i kahi maloʻo a me ka haʻahaʻa haʻahaʻa, a ʻoi aku paha ka pilikia me nā huahana metala a me ka haʻihaʻi ma 0 ℃.

ʻO ka polyamid pa6 ka maikaʻi o ka lubricity ponoʻī a me ke kūpaʻa ʻaʻahu maikaʻi.

Kūʻē maikaʻi i ka ʻaila, eg.ʻaila.

He kiʻekiʻe ka ikaika luhi, ma ka maʻamau 20% a 30% o ka ikaika tensile.ʻO ka ikaika luhi o PA6 a me PA66 hiki ke piʻi ma kahi o 22MPa, ʻelua wale nō i ka POM (35MPa) a ʻoi aku ka kiʻekiʻe ma mua o PC (10-14MPa).ʻO ke kaʻina e pili ana i ka ikaika luhi: POM> PBT, PET> PA66> PA6> PC> PSF> PP.

Paʻa kiʻekiʻe, PA66: 108 a 120HRR;PA6120HRR.

ʻOi aku ka maikaʻi ma mua o PP a me PE, a ʻoi aku ka maikaʻi ma mua o ABS a me POM.

ʻAʻole hiki ke hoʻopaʻa ʻia i ke koʻikoʻi: Pono e hoʻokō ʻia ka hoʻomaʻamaʻa ʻana a hoʻomaʻemaʻe paha ma hope o ka hana ʻana i nā huahana.
