Polythene ndi imodzi mwamapulasitiki otchuka kwambiri padziko lapansi. Ndi polima yosunthika yomwe imayenera kugwiritsidwa ntchito mosiyanasiyana, kuchokera pamakanema otchinga chinyezi cholemetsa kuti amange zatsopano mpaka zopepuka, matumba osinthika ndi makanema.

Mitundu iwiri ikuluikulu ya PE imagwiritsidwa ntchito mufilimuyi ndi makina osindikizira osinthika - LDPE (otsika kachulukidwe), omwe amagwiritsidwa ntchito popanga mapepala ndi mafilimu olemetsa monga matumba a moyo wautali ndi matumba, zitsulo za polyethylene, mafilimu otetezera, matumba a chakudya, ndi zina zotero.HDPE (kachulukidwe kwambiri), Kwa tote zoonda kwambiri, matumba atsopano, ndi mabotolo ndi zipewa.

Palinso mitundu ina ya mitundu ikuluikulu iwiriyi. Zogulitsa zonse zimakhala ndi nthunzi wabwino kapena zotchinga chinyezi ndipo zimakhala zoziziritsa kukhosi.

Posintha mawonekedwe a polyethylene ndi mafotokozedwe, opanga / mapurosesa amatha kusintha momwe zimakhudzira komanso kukana misozi; kumveka ndi kumva; kusinthasintha, kukhazikika, ndi zokutira/laminating/kusindikiza. PE ikhoza kubwezeretsedwanso, ndipo matumba ambiri a zinyalala, mafilimu aulimi, ndi zinthu zamoyo wautali monga mabenchi a paki, ma bollards, ndi mabokosi a zinyalala amagwiritsa ntchito polyethylene yobwezeretsanso. Chifukwa cha kuchuluka kwake kwa calorific,PE amaperekakuchira bwino kwamphamvu kudzera pakuwotcha koyera.

Mukuyang'ana kugula HDPE?

ntchito
Migolo ya mankhwala, mitsuko ya pulasitiki, mabotolo agalasi, zoseweretsa, ziwiya za pikiniki, ziwiya zapakhomo ndi zakukhitchini, zotsekera chingwe, zikwama za tote, zotengera chakudya.

Zosinthika, zowoneka bwino / waxy, zosagwirizana ndi nyengo, kulimba kwa kutentha kochepa (mpaka -60'C), zosavuta kuzikonza ndi njira zambiri, zotsika mtengo, kukana mankhwala abwino.

Kafukufuku waposachedwa

Zotengera za m'munda zopangidwa ndi polyethylene yolimba kwambiri. Zotsika mtengo, zolimba kwambiri komanso zosavuta kuziwombera zimapangitsa kuti nkhaniyi ikhale yosankha mwachilengedwe mipando yamaluwa.

Botolo la pulasitiki la HDPE
Mabotolo apulasitiki olemera kwambiri a polyethylene (HDPE) ndi njira yotchuka yopangira mkaka ndi misika yamadzi atsopano. Ku UK, mwachitsanzo, pafupifupi mabotolo odyetsa 4 biliyoni a HDPE amapangidwa ndikugulidwa chaka chilichonse.

HDPE imapereka maubwino ambiri kwa opanga, ogulitsa ndi ogula.

Ubwino wa mabotolo a HDPE
Obwezerezedwanso: Mabotolo a HDPE ndi 100% otha kubwezeretsedwanso, kotero zinthuzo zitha kugwiritsidwanso ntchito

Zokhazikika: HDPE imapereka mwayi wophatikizanso zinthu zobwezerezedwanso muzogulitsa

Kupepuka Kosavuta: Mabotolo a HDPE Amapereka Mwayi Wofunika Wopepuka

Zosinthika kwambiri: botolo la pulasitiki lokhalo lomwe lingagwiritsidwe ntchito ngati mkaka wosakanizidwa, kapena ngati UHT kapena chotchinga mkaka chotchinga chowonjezera botolo.

Kusavuta kugwiritsa ntchito: Mtundu wokhawo wa ma CD omwe amalola zogwirira ntchito zophatikizika ndikutsanulira mabowo kuti agwire ndikutsanulira.

Otetezeka komanso otetezeka: Mtundu wokhawo wa phukusi womwe ungakhale ndi chisindikizo chowonekera kunja kapena chisindikizo cha kutentha kuti chiteteze kudontha, kusunga kutsitsi kwa zinthu, ndikuwonetsa umboni wa kusokoneza.

Zamalonda: Mabotolo a HDPE amapereka mwayi wochuluka wa malonda, monga kusindikiza mwachindunji pazinthu, kusindikiza mwachindunji pamanja kapena chizindikiro, komanso kutha kusintha mawonekedwe kuti awoneke bwino pa alumali.

Innovation: Kutha kukankhira malire ndikukwaniritsa zitsogozo zatsopano pogwiritsa ntchito zida zomangira.

mfundo zachilengedwe
Mabotolo a ana a HDPE ndi amodzi mwazinthu zopakidwanso zobwezerezedwanso kwambiri ku UK, zomwe data yochokera ku Recoup ikuwonetsa kuti pafupifupi 79% ya mabotolo a ana a HDPE amasinthidwanso.
Pafupifupi,HDPE mabotoloku UK tsopano ndi 15% opepuka kuposa momwe analiri zaka zitatu zapitazo

Komabe, mapangidwe atsopano monga botolo la Infini lopambana mphoto zikutanthauza kuti tsopano ndizotheka kuchepetsa kulemera kwa mabotolo wamba mpaka 25% (kutengera kukula)

Pafupifupi, mabotolo a HDPE ku UK amakhala ndi 15% zobwezerezedwanso

Komabe, kupita patsogolo kwaukadaulo komanso kupangidwa kwatsopano kwa zinthu kukutanthauza kuti zinthu zatsopano zatheka. Mwachitsanzo, mu 2013, Nampak adawonjezera 30 peresenti yobwezeretsanso HDPE ku mabotolo ake a mkaka wa Infini, dziko loyamba - zaka ziwiri patsogolo pa makampani.
