Reka tubanze turebe inkomoko yabo n'umugongo (imiterere ya molekile). LDPE (polyethylene nkeya): Nkigiti kibisi! Urunigi rwarwo rufite amashami maremare menshi, bivamo imiterere idahwitse, idasanzwe. Ibisubizo mubucucike buke (0,91-0.93 g / cm³), byoroshye, kandi byoroshye. HDPE (polyethylene yuzuye): Nka basirikare bakurikiranye! Urunigi rwarwo rufite amashami make cyane, bivamo umurongo ugizwe neza kandi wuzuye. Ibi biha ubucucike buri hejuru (0,94-0.97 g / cm³), bikomeye, kandi bikomeye. LLDPE (umurongo muto-wuzuye wa polyethylene): verisiyo "yahindutse" ya LDPE! Umugongo wacyo ni umurongo (nka HDPE), ariko hamwe n'amashami magufi agabanijwe. Ubucucike bwabwo buri hagati yibi byombi (0.915-0.925 g / cm³), bihuza guhinduka hamwe nimbaraga zisumba izindi.
Ibikorwa by'ingenzi Incamake: LDPE: Yoroheje, ikorera mu mucyo, yoroshye kuyitunganya, kandi muri rusange igiciro gito. Nyamara, ibabazwa nimbaraga nke, gukomera, hamwe nubushyuhe bukabije, bigatuma byoroha. LLDPE: Ikomeye! Itanga ingaruka zidasanzwe, kurira, no kurwanya gucumita, imikorere yubushyuhe bwo hasi cyane, no guhinduka neza, ariko birakomeye kuruta LDPE. Gukorera mu mucyo na barrière biruta LDPE, ariko gutunganya bisaba kwitonda. HDPE: Ikomeye! Itanga imbaraga nyinshi, gukomera cyane, kurwanya imiti myiza, kurwanya ubushyuhe bwiza, hamwe ninzitizi nziza. Ariko, irababazwa no guhinduka guke no gukorera mu mucyo.
Ikoreshwa he? Biterwa na porogaramu!
Porogaramu ya LDPE ikubiyemo: imifuka itandukanye yo gupakira ibintu byoroshye (imifuka y'ibiryo, imifuka y'imigati, imifuka y'imyenda), gupfunyika plastike (mu rugo ndetse no mu bucuruzi bumwe na bumwe), ibikoresho byoroshye (nko gukata amacupa y'ubuki na ketchup), insinga hamwe na insinga, insinga zoroheje zashizwemo ibice (nk'ibikarito by'amacupa n'ibikinisho).
Imbaraga za LLDPE zirimo: firime zikora cyane nko gupfunyika kurambura (ugomba kuba ufite ibikoresho byo gupakira inganda), imifuka ipakira ibintu byinshi (kubiryo nifumbire), firime yubuhinzi bwimbuto (yoroheje, ikaze, kandi iramba), imifuka minini yimyanda (itavunika), hamwe nuburyo buringaniye bwa firime. Gutera inshinge ibice bisabwa gukomera harimo ingunguru, ibipfundikizo, hamwe nibikoresho bikikijwe. Imiyoboro ya pipe na jacketing ya kabili nayo irakoreshwa.
Imbaraga za HDPE zirimo: ibikoresho bikomeye nk'amacupa y’amata, amacupa yo kumesa, amacupa y’imiti, hamwe n’ibikoresho binini bya shimi. Imiyoboro n'ibikoresho birimo imiyoboro y'amazi (amazi akonje), imiyoboro ya gaze, n'imiyoboro y'inganda. Ibicuruzwa bidafite akamaro birimo ingoma zamavuta, ibikinisho (nkibice byubaka), hamwe n’ibigega bya peteroli. Ibicuruzwa byatewe inshinge birimo agasanduku k'ibicuruzwa, pallets, agacupa, n'ibikenerwa bya buri munsi (ibikarabiro n'intebe). Filime: Amashashi yo guhaha (sturdier), imifuka y'ibicuruzwa, hamwe na T-shirt.
Igitabo cyo gutoranya interuro imwe: Urashaka imifuka yoroshye, ibonerana, kandi ihendutse / firime? ————— LDPE. Urashaka firime ikabije, irwanya amarira, na firime idashobora gucumita, cyangwa bisaba ubukonje buke? —LLDPE (cyane cyane kubipakira biremereye no kurambura firime). Urashaka amacupa akomeye, akomeye, arwanya imiti / ingunguru / imiyoboro y'amazi? —HDPE
