I-Polythene yenye yeeplastiki ezidumileyo kwihlabathi.Yipolymer eguquguqukayo efanelekileyo kuluhlu olubanzi lwezicelo, ukusuka kwiifilim zokuthintela ukunyakama kobunzima bokwakhiwa olutsha ukuya kwiingxowa ezikhaphukhaphu, eziguquguqukayo kunye neefilimu.

Iintlobo ezimbini eziphambili ze-PE zisetyenziselwa ifilimu kunye necandelo lokupakisha eliguquguqukayo - i-LDPE (ubuninzi obuphantsi), ngokuqhelekileyo isetyenziselwa iipalati kunye neefilimu ezinzima ezifana nezikhwama zobomi obude kunye neengxowa, i-polyethylene tunnels, iifilimu ezikhuselayo, izikhwama zokutya, njl.HDPE (uxinzelelo oluphezulu), Kwiitotes ezininzi ezincinci zegauge, iingxowa zemveliso entsha, kunye neebhotile kunye neekepusi.

Kukho ezinye iintlobo zezi ntlobo zimbini ziphambili.Zonke iimveliso zinomphunga olungileyo okanye iipropathi zokuthintela ukufuma kwaye zingasebenzi ngokwekhemikhali.

Ngokutshintsha i-polyethylene formulations kunye neenkcukacha, abavelisi / abaqhubekisi banokuhlengahlengisa impembelelo kunye nokuchasana nokukrazula;ukucaca kunye nokuziva;ukuguquguquka, ukwakheka, kunye nokwaleka/i-laminating/ukushicilela amandla.I-PE inokuphinda isetyenziswe, kwaye iingxowa ezininzi zenkunkuma, iifilimu zezolimo, kunye neemveliso zexesha elide ezifana neebhentshi zepaki, i-bollards, kunye neebhokisi ze-litter zisebenzisa i-polyethylene ehlaziyiweyo.Ngenxa yexabiso layo eliphezulu lekhalori,PE inikezaukubuyisela amandla ngokugqibeleleyo ngokutshisa okucocekileyo.

Ngaba ujonge ukuthenga i-HDPE?

Imizekelo yangoku

Izikhongozeli zegadi ezenziwe nge-polyethylene ephezulu.Iindleko eziphantsi, ukuqina okuphezulu kunye nokulula kokubumba ukubetha kwenza le mpahla ibe yinto ekhethekileyo yefenitshala yegadi.

HDPE ibhotile yeplastiki
Iibhotile zeplastiki ze-high-density polyethylene (HDPE) lukhetho oludumileyo lokupakisha kubisi kunye neemarike zejusi entsha.E-UK, umzekelo, malunga ne-4 yeebhiliyoni zeebhotile ze-HDPE ziveliswa kwaye zithengwe ngonyaka.

I-HDPE inikezela ngeenzuzo ezininzi kubavelisi, abathengisi kunye nabathengi.

Izinto eziluncedo kwiibhotile ze-HDPE
Inokuphinda isetyenziswe: Iibhotile ze-HDPE ziyi-100% ezinokuphinda zisetyenziswe, ngoko ke imathiriyeli ingaphinda isetyenziswe

Uzinzo: I-HDPE inika ithuba lokudibanisa izixhobo ezisetyenzisiweyo kwakhona kwikhonkco lokubonelela

UkuKhanya okuLula: Iibhotile zeHDPE zibonelela ngamaThuba aBalulekileyo wokuKhanya

Iguquguquka kakhulu: ekuphela kwebhotile yeplastiki enokusetyenziswa njenge-monolayer yobisi e-pasteurized, okanye njenge-UHT okanye i-sterilized milk barrier co-extruded bottle

Ukusebenziseka lula: Ekuphela kohlobo lokupakisha oluvumela izibambo ezidityanisiweyo kunye nokugalela imingxuma yokubamba okulawulwayo kunye nokugalela.

Ikhuselekile kwaye ikhuselekile: Uhlobo lwephakheji kuphela olunokuba nesitywina sangaphandle esibonakalayo okanye itywina lobushushu elingeniswayo ukuthintela ukuvuza, ukugcina ukutsha kwemveliso, kunye nokubonisa ubungqina bokuphazamiseka.

Urhwebo: Iibhotile ze-HDPE zinika uluhlu olupheleleyo lwamathuba okuthengisa, njengokushicilela ngokuthe ngqo kwizinto eziphathekayo, ukuprinta ngokuthe ngqo kwi-sleeve okanye ileyibhile, kunye nokukwazi ukuguqula imilo ukuze ibonakale kwi-shelf.

Utshintsho: Ukukwazi ukutyhala imida kunye nokufezekisa imida emitsha ngokusetyenziswa ngokutsha kwezixhobo zokubumba.

iinyani zokusingqongileyo
Iibhotile zomntwana ze-HDPE yenye yezona zinto zipakishwayo ziphinda zisetyenziswe e-UK, kunye nedatha evela kwi-Recoup ebonisa ukuba malunga ne-79% yeebhotile ze-HDPE zihlaziywa.
Kwi-avareji,Iibhotile ze-HDPEe-UK ngoku zikhaphukhaphu nge-15% kunokuba zazinjalo kwiminyaka emithathu edlulileyo

Nangona kunjalo, ukuyila okutsha okufana nebhotile ye-Infini ephumelele ibhaso kuthetha ukuba ngoku kunokwenzeka ukunciphisa ubunzima beebhotile eziqhelekileyo ukuya kuthi ga kwi-25% (kuxhomekeke kubungakanani)

Ngokwe-avareji, iibhotile ze-HDPE e-UK ziqulethe ukuya kuthi ga kwi-15% yezinto ezisetyenzisiweyo

Nangona kunjalo, ukuhambela phambili kwetekhnoloji kunye noyilo oluyilayo lweemveliso kuthetha ukuba impumelelo entsha inokwenzeka.Ngokomzekelo, kwi-2013, i-Nampak yongeza i-30 yeepesenti iphinda isetyenziswe i-HDPE kwiibhotile zayo zobisi ze-Infini, ihlabathi lokuqala-iminyaka emibini ngaphambi kokujoliswe kuyo kwishishini.
