Bambanci tsakanin igiya polyethylene da igiya polypropylene

Kwanan nan, abokin ciniki ya yi tambaya game da farashin PP danline igiya.Abokin ciniki shine masana'anta wanda ke fitar da ragar kamun kifi.Yawancin lokaci, suna amfani da igiya na polyethylene. Amma igiyar polyethylene ya fi santsi kuma mai kyau da sauƙi don kwance bayan kullin.Amfanin igiyar PP danline shine tsarin fiber ta.Fiber ɗin yana da ɗan ƙanƙara kuma kullin ba mai santsi ba ne.

A ka'ida, tsarin kwayoyin propylene shine: CH3CH2CH3, kuma tsarin kwayoyin ethylene shine: CH3CH3.

Tsarin polypropylene shine kamar haka:

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

Tsarin polyethylene shine kamar haka:

- (CH2-CH2-CH2-CH2) n —-

Ana iya gani daga tsarin cewa polypropylene yana da sarkar reshe ɗaya fiye da polyethylene.Bayan an yi igiya, saboda rawar da ke tattare da sarkar reshe, igiya na polypropylene yana da ƙarfi mai ƙarfi fiye da polyethylene kuma kullin ba ya zamewa.

Polyethylene igiya ya fi m da santsi fiye da polypropylene, kuma yana jin taushi.

Yawan polypropylene shine 0.91, kuma yawan polyethylene shine 0.93.Don haka igiyar PE ta fi PP nauyi.
