Uyu munsi tuzamenyekanisha ibintu bitatu byingenzi kuri epe net, irimo LDPE HDPE PP.

一、Itandukaniro nyamukuru hagati ya LDPE (polyethylene yubucucike buke) na HDPE (polyethylene yuzuye) iri mubucucike bwabo, imiterere yumubiri, imikoreshereze, nibindi.

1. Ubucucike no kugaragara:

Ubucucike bwa LDPE mubusanzwe buri hagati ya 0.910-0.940g / cm³, mugihe ubucucike bwa HDPE buri hagati ya 0.940-0.976g / cm³.

LDPE ifite amata yera yera kandi irasobanutse kurwego runaka mubice bito, mugihe HDPE isanzwe itagaragara kandi ifite amata yera kandi asa neza.

2. Imiterere yumubiri:

LDPE iroroshye, ifite ubukana bwiza, gukorera mu mucyo, no kunyerera. Ifite imiterere idahwitse mugihe cyo kubumba no gutunganya, kandi biragoye guhuza.

HDPE ifite imbaraga nyinshi, gukomera, hamwe no gukomera, hafi ya PP (polypropilene), ikaze kurusha PP, kandi ifite ubushyuhe bwiza.

3. Koresha:

LDPE ifite ububobere buke bwo gushonga, amazi meza, kandi byoroshye kuyatunganya. Irakwiriye kubyara imiyoboro y'amazi yo kunywa, nibindi.

HDPE ikwiranye no gukora amanota yo gushushanya, igipimo cyo guterwa inshinge, icyiciro cya hollow hamwe nibicuruzwa byerekana amafirime, nk'urushundura rwo kuroba, amacupa y'ibinyobwa n'imifuka yo gupakira.

4. Kurwanya imiti:

Byombi bifite imbaraga zo kurwanya imiti myinshi yo mu nganda n’inganda, ariko HDPE irwanya aside, ruswa ya alkali hamwe n’umuti ukomoka ku buhinzi.

5. Kurwanya ubushyuhe no kurwanya gusaza:

LDPE ifite ubushyuhe buke, kurwanya gusaza hamwe n’ibidukikije byangiza ibidukikije nka HDPE, kandi ikunda gusaza, kubora no guhinduka ibara.

HDPE ifite ubushyuhe bwiza bwo hejuru ariko irwanya ubushyuhe buke. Ingaruka ni uko kurwanya gusaza kwayo no guhangana n’ibidukikije bidahungabana bitameze neza nka LDPE.

二、Itandukaniro nyamukuru hagati yibikoresho bya PP na PE nibi bikurikira:

1. Ibigize: Igice nyamukuru cya PP ni polypropilene, mugihe igice kinini cya PE ari polyethylene.

2. PE ni ibikoresho bizwi byo guhuza ibiryo ku isi, bidafite uburozi, uburyohe, Ntabwo binuka, byunvikana nkibishashara, byubahiriza amahame yisuku yo gupakira ibiryo, bifite ihindagurika ryiza, ntabwo byangiritse byoroshye, kandi bifite ubushyuhe buhebuje.

3. Ahantu ho gukoreshwa: PP irashobora gukoreshwa mugukora ibyuka bihumanya ikirere, firime ya mulch, amacupa yumuco, nibindi, kandi birashobora no gukoreshwa mugukora udusanduku two kugurisha ibiryo, ibikapu byibiribwa, nibindi PE birashobora gutunganywa no kubumba, kubisohora , gushushanya inshinge nubundi buryo, kandi bikoreshwa cyane mugukora firime, ibicuruzwa bidafite akamaro, nibindi.
