He aha nā ʻano like ʻole o ka Polypropylene?

ʻElua ʻano nui o ka polypropylene i loaʻa: homopolymers a me copolymers. Hoʻokaʻawale hou ʻia nā copolymers i nā copolymers poloka a me nā copolymers random.

ʻOi aku ka maikaʻi o kēlā me kēia ʻāpana i kekahi mau noi ma mua o nā mea ʻē aʻe. Kapa pinepine ʻia ʻo Polypropylene ʻo "steel" o ka ʻoihana plastik ma muli o nā ʻano like ʻole e hiki ai ke hoʻololi a hoʻoponopono ʻia paha i mea e lawelawe maikaʻi ai i kahi kumu.

Loaʻa ʻia kēia ma ka hoʻokomo ʻana i nā mea hoʻohui kūikawā iā ia a i ʻole ma ka hana ʻana iā ia ma ke ʻano kūikawā. He waiwai koʻikoʻi kēia adaptability.

Homopolymer polypropylenehe papa hana nui. Hiki iā ʻoe ke noʻonoʻo i kēia e like me ke kūlana paʻamau o ka mea polypropylene.Block copolymerʻO ka polypropylene nā ʻāpana co-monomer i hoʻonohonoho ʻia i loko o nā poloka (ʻo ia hoʻi, ma ke ʻano maʻamau) a loaʻa ma waena o 5% a 15% ethylene.

Hoʻomaikaʻi ʻo Ethylene i kekahi mau waiwai, e like me ka pale ʻana i ka hopena aʻo nā mea hoʻohui ʻē aʻe e hoʻomaikaʻi i nā waiwai ʻē aʻe.

copolymer randompolypropylene – ʻaʻole e ālai i ka copolymer polypropylene – ua hoʻonohonoho ʻia nā ʻāpana co-monomer ma nā ʻano like ʻole a i ʻole ma ka mole polypropylene.

Hoʻohui pinepine ʻia lākou me nā wahi āpau ma waena o 1% a 7% ethylene a koho ʻia no nā noi kahi e makemake ʻia ai kahi huahana ʻoi aku ka maʻalahi a maʻalahi.
