Polyacrylonitrile/PAN/CAS:25014-41-9

Whakaahuatanga:

Ko te Polyacrylonitrile he momo kapia hangai i hangaia mā te whakapūhuitanga rauropi kore utu o te acrylonitrile. Nō te whānau kapia kiriaku. He kirihou wera, ā, he ātete ki te nuinga o ngā whakarewa me ngā matū nā te kaha o ngā hononga matū i waenganui i ngā rōpū nitrile. He momo kapia maha-whakamahinga ka taea te whakamahi hei whakaputa i ngā momo hua maha pēnei i ngā muka mō ngā kakahu, te kiriuhi tātari ultra, te muka waro me ngā muka tuwhera mō te osmosis whakamuri. Ka taea hoki te whakamahi i tōna homopolymer hei muka i roto i te taupee o waho, ngā rā mō ngā waka tere, me te raima whakakaha-muka. Ka taea hoki te whakamahi mō te whakaputa i ngā papanga ātete mura (FR).

Whakatakotoranga

Whakamahinga

Nā ōna āhuatanga motuhake pērā i te pumau ki te pirau UV, te iti o te mātotoru, te kaha me te modulus o te ngāwari, te pumau wera, te kore-whakarewa me te ātete matū, he polymer nui te Polyacrylonitrile mō te whānuitanga o ngā tono. Nō reira, e whakamahia ana i roto i ngā tono kakahu nā ōna āhuatanga rite ki te huruhuru hipi, i roto i te hanga muka waro, ngā kiriuhi tātari, ngā muka mō te whakakaha sima, ngā rā mō ngā waka tere, ngā papanga taupee i roto i ngā tono o waho, ngā muka motuhake mō te whakamarumaru oro me te wera, ngā muka ārai-mura me te hanga felts mō ngā pūnaha tātari hau wera.
Ko ngā Copolymers kei roto ko te polyacrylonitrile, he ātete mura, ka whakamahia hei muka hei hanga kākahu whatu, pērā i ngā tōkena me ngā hāte, tae atu ki ngā hua o waho pērā i ngā tēneti. Ko te Poly(acrylonitrile-co-butadiene-co--styrene)(ABS) me te Poly(styrene-co-acrylonitrile)(SAN) ka whakamahia hei kirihou. He polymer mama, he tino kaha hoki te ABS. He tino mama, he kaha hoki hei whakamahi i roto i te hanga wāhanga tinana motuka. Nō reira, ka māmā ake ngā motuka mā te whakamahi i te wahie iti iho, ā, ka iti ake te poke.
Ko te kaha o te ABS e ahu mai ana i ngā rōpū nitrile kei roto i ōna waeine acrylonitrile. He tino polar ngā rōpū nitrile; nō reira, ka taea e rātou te kukume tetahi ki tetahi. Mā tēnei āhuatanga ka taea e ngā utu rerekē i runga i ngā rōpū nitrile te whakau tetahi ki tetahi. Mā tēnei kukume kaha ka mau pūmau ngā mekameka ABS, nō reira, ka tino kaha te rauemi. Hei tāpiri, ko te polybutadiene rapa kei roto ka hanga te ABS hei polymer pakari.
