Ni ubuhe bwoko butandukanye bwa polypropylene?

Hari ubwoko bubiri bw'ingenzi bwa polypropylene buboneka: homopolymers na copolymers. Copolymers zigabanyijemo kandi ibice bibiri: block copolymers na random copolymers.

Buri cyiciro gihuye neza n'ibindi bikorwa bimwe na bimwe kurusha ibindi. Polypropylene ikunze kwitwa "icyuma" cy'inganda za pulasitiki bitewe n'uburyo butandukanye ishobora guhindurwamo cyangwa guhindurwa kugira ngo igere ku ntego runaka.

Ibi bikunze kugerwaho binyuze mu kuyishyiramo inyongeramusaruro zidasanzwe cyangwa mu kuyikora mu buryo bwihariye. Uku kwihuza n'ibindi ni ingenzi cyane.

Polypropylene ya homopolymerni urwego rusange rw'intego. Ushobora gutekereza ibi nk'uko ibintu bya polypropylene bimeze mbere.Kopolimeri y'amatafariPolypropylene ifite ibice bya co-monomer bitondetse mu bice (ni ukuvuga mu buryo busanzwe) kandi irimo hagati ya 5% na 15% bya ethylene.

Ethylene yongera imiterere imwe n'imwe, nko kudakora neza mu gihe izindi nyongeramusaruro zongera imiterere yindi.

Kopolimeri idasanzwePolypropylene – bitandukanye na polypropylene ya copolymer ifunganye – ifite ibice bya co-monomer bitondetse mu buryo budasanzwe cyangwa butunguranye ku gice cya molecule ya polypropylene.

Ubusanzwe zishyirwa hamwe na ethylene iri hagati ya 1% na 7% kandi zitoranywa kugira ngo zikoreshwe aho ukeneye ikintu cyoroshye kandi gisobanutse neza.
