Itandukaniro riri hagati yumugozi wa polyethylene nu mugozi wa polypropilene

Vuba aha, umukiriya yabajije igiciro cyumugozi wa PP danline.Umukiriya ni uruganda rwohereza inshundura zo kuroba.Mubisanzwe, bakoresha umugozi wa polyethylene.Ariko umugozi wa polyethylene uroroshye kandi mwiza kandi byoroshye kurekura nyuma yo kuboha.Ibyiza bya PP danline umugozi nuburyo bwa fibre.Fibre irasa naho ipfundo ntirinyerera.

Mubyukuri, formulaire ya molekile ya propylene ni: CH3CH2CH3, na formula ya molekile ya Ethylene ni: CH3CH3.

Imiterere ya polypropilene niyi ikurikira:

- (CH2-CH (CH3) -CH2-CH (CH3) -CH2-CH (CH3)) n —-

Imiterere ya polyethylene niyi ikurikira:

- (CH2-CH2-CH2-CH2) n —-

Birashobora kugaragara uhereye kumiterere ko polypropilene ifite urunigi rumwe rwishami kuruta polyethylene.Umugozi umaze gukorwa, kubera uruhare rwumunyururu wishami, umugozi wa polypropilene ufite imbaraga zikomeye kuruta polyethylene kandi ipfundo ntirinyerera.

Umugozi wa polyethylene uroroshye kandi woroshye kuruta polypropilene, kandi ukumva woroshye.

Ubucucike bwa polypropilene ni 0,91, n'ubucucike bwa polyethylene ni 0,93.Umugozi wa PE rero uremereye kuruta umugozi wa PP.
