Naịlọn ọ bụ UHMWPE?

Ee e. Nylon siri ike ma nwee nnukwu nguzogide okpomọkụ, ọ dịkwa mma maka ịme shells, ngwá ọrụ, ihe eji eme ihe, wdg. Polyethylene dị nro ma nwee obere nkwụsị okpomọkụ.Enwere ike ịfụ ya na fim ma mee ka ọ bụrụ karama.

Polyethylene (PE) bụ resin thermoplastic kwadebere site na polymerization nke ethylene.Na ụlọ ọrụ, ọ na-agụnye copolymer nke ethylene na obere ego nke α-olefins.Polyethylene enweghị isi, anaghị egbu egbu, ọ na-adị ka wax, ma nwee oke nguzogide okpomọkụ dị ala, ezigbo nkwụsi ike kemịkalụ na iguzogide ọtụtụ acid na alkali corrosion.Na-adịghị ike n'ozuzu ihe mgbaze na ọnụ ụlọ okpomọkụ, na obere mmiri absorption na magburu onwe mkpuchi eletrik.Polyethylene nwere ihe eji arụ ọrụ n'ozuzu, ike mgbada dị ala, nguzogide na-adịghị mma na nguzogide mmetụta dị mma.Enwere ike ịhazi polyethylene site na ịkpụzi ihe, extrusion na ịkpụzi injection, a na-ejikwa ya n'ichepụta ihe nkiri, ngwaahịa oghere, eriri na ihe ndị dị mkpa kwa ụbọchị.

A na-akpọkarị Polyamide dị ka Nylon, na aha Bekee bụ Polyamide (PA maka mkpụmkpụ), njupụta nke 1.15g/cm.Ọ bụ okwu izugbe maka resins thermoplastic nwere otu amide ugboro ugboro -[NHCO] - n'ime ọkpụkpụ azụ molekụla, gụnyere aliphatic PA, aliphatic-aromatic PA na aromatic PA.N'ime ha, aliphatic PA nwere ọtụtụ ụdị, nnukwu mmepụta na ngwa sara mbara, na aha ya dabere na ọnụọgụ carbon carbon dị na monomer synthetic.Ọ bụ ndị American chemist carothers a ma ama na ndị otu nyocha ya chepụtara ya.
