I-Polythene yenye yezona plastiki zidumileyo ehlabathini. Yi-polymer eguquguqukayo efanelekileyo kwiintlobo ngeentlobo zezicelo, ukusuka kwiifilimu zokuthintela ukufuma ezinzima zokwakha ezintsha ukuya kwiingxowa kunye neefilimu ezikhaphukhaphu neziguquguqukayo.

Zimbini iintlobo eziphambili ze-PE ezisetyenziswa kwicandelo lefilimu kunye nelokupakisha eliguquguqukayo – i-LDPE (uxinano oluphantsi), edla ngokusetyenziselwa iipallet kunye neefilimu ezinzima ezifana neengxowa kunye neengxowa ezihlala ixesha elide, iityhubhu ze-polyethylene, iifilimu zokukhusela, iingxowa zokutya, njl.njl. kunyeI-HDPE (uxinano oluphezulu), Kwiimpahla ezininzi ezisetyenziswa xa unxiba izinto ezincinci, iingxowa zemveliso entsha, kunye neebhotile kunye neekepusi.

Kukho ezinye iintlobo zezi ntlobo zimbini ziphambili. Zonke iimveliso zineempawu ezilungileyo zokuthintela umphunga okanye ukufuma kwaye azinazo iikhemikhali.

Ngokutshintsha iindlela zokwenziwa kwe-polyethylene kunye neenkcukacha, abavelisi/abaprosesa banokulungisa impembelelo kunye nokumelana nokukrazula; ukucaca kunye nokuziva; ukuguquguquka, ukwakheka, kunye nokukwazi ukugquma/ukulaminetha/ukuprinta. I-PE ingaphinda isetyenziswe, kwaye iingxowa ezininzi zenkunkuma, iifilimu zezolimo, kunye neemveliso ezihlala ixesha elide ezifana neebhentshi zepaki, ii-bollards, kunye neebhokisi zenkunkuma zisebenzisa i-polyethylene ephinde yasetyenziswa. Ngenxa yexabiso layo eliphezulu leekhalori,Izibonelelo ze-PEukubuyiswa kwamandla okugqwesileyo ngokutshisa okucocekileyo.

Ngaba ujonge ukuthenga i-HDPE?

Izifundo zangoku

Izikhongozeli zegadi ezenziwe nge-polyethylene enobunzima obuphezulu. Ixabiso eliphantsi, ukuqina okuphezulu kunye nokulula kokubumba kwenza le nto ibe lukhetho lwendalo lwefenitshala yegadi.

Ibhotile yeplastiki yeHDPE
Iibhotile zeplastiki ze-polyethylene enoxinano oluphezulu (HDPE) ziyindlela ethandwayo yokupakisha kwiimarike zobisi kunye nejusi entsha. Umzekelo, e-UK, malunga neebhotile zokutya ze-HDPE eziziibhiliyoni ezi-4 zenziwa kwaye zithengwa minyaka le.

I-HDPE inika iingenelo ezininzi kubavelisi, abathengisi kunye nabathengi.

Iingenelo zeebhotile zeHDPE
Ingasetyenziswa kwakhona: Iibhotile zeHDPE zingasetyenziswa kwakhona nge-100%, ngoko ke izinto ezisetyenzisiweyo zingasetyenziswa kwakhona

I-Sustainable: I-HDPE inika ithuba lokudibanisa kwakhona izinto ezisetyenzisiweyo kwikhonkco lokubonelela

Ukukhanya okulula: Iibhotile zeHDPE zibonelela ngamathuba abalulekileyo okukhanya

Iyakwazi ukuguquguquka kakhulu: yibhotile yeplastiki ekuphela kwayo engasetyenziswa njenge-monolayer yobisi olufakwe i-pasteurized, okanye njenge-UHT okanye ibhotile ekhutshwe kunye ne-sterilized milk barrier co-extruded

Ukulula kokusetyenziswa: Uhlobo olulodwa lokupakisha oluvumela izibambo ezidibeneyo kunye nemingxunya yokugalela ukuze kubanjwe kwaye kugalelwe ngokulawulayo

Ikhuselekile kwaye ikhuselekile: Uhlobo lwephakheji olukuphela kwalo olunokuba nesitywino sangaphandle esibonakalayo sokuphazanyiswa okanye isitywino sobushushu bokungenisa ukuthintela ukuvuza, ukugcina ubutsha bemveliso, kunye nokubonisa ubungqina bokuphazamiseka

Ezorhwebo: Iibhotile zeHDPE zibonelela ngamathuba okuthengisa apheleleyo, njengokuprinta ngqo kwimpahla, ukuprinta ngqo kwisikhwama okanye ilebhile, kunye nokukwazi ukutshintsha imo ukuze ibonakale eshelufini.

Ubuchule: Ukukwazi ukutyhala imida nokufezekisa imigangatho emitsha ngokusebenzisa izixhobo zokubumba eziphucukileyo.

iinyaniso zokusingqongileyo
Iibhotile ze-HDPE zeentsana zezinye zezinto zokupakisha eziphinda zisetyenziswe kakhulu e-UK, idatha evela kwiRecoup ibonisa ukuba malunga ne-79% yeebhotile ze-HDPE zeentsana ziyaphinda zisetyenziswe.
Kwi-avareji,Iibhotile zeHDPEe-UK ngoku zilula nge-15% kunokuba zazinjalo kwiminyaka emithathu eyadlulayo

Nangona kunjalo, uyilo olutsha olufana nebhotile ye-Infini ephumelele amabhaso luthetha ukuba ngoku kunokwenzeka ukunciphisa ubunzima beebhotile eziqhelekileyo ukuya kuthi ga kwi-25% (kuxhomekeke kubukhulu)

Ngokomndilili, iibhotile zeHDPE e-UK ziqulathe ukuya kuthi ga kwi-15% yezinto ezisetyenzisiweyo

Nangona kunjalo, inkqubela phambili kubuchwepheshe kunye noyilo olutsha lweemveliso kuthetha ukuba impumelelo entsha inokwenzeka. Umzekelo, ngo-2013, iNampak yongeze ama-30 ekhulwini e-HDPE ephinde yasetyenziswa kwiibhotile zayo zobisi ze-Infini, ihlabathi lokuqala—iminyaka emibini ngaphambi kwenjongo yoshishino.
