Yintoni i-pe?
I-PE, eyaziwa ngokuba yiPolythyylene (Polythylene), yenye yezona zinto zisetyenziswa ngeplastiki zeplastiki emhlabeni. Ngenxa yepropathi yayo ebalaseleyo yomzimba kunye nekhemikhali, izixhobo ze-PE zisetyenziswa kuluhlu olubanzi lwamashishini. Ukusuka kwiingxowa zokupakisha kwizinto ezinamafutha, i-polylethylene iphantse yonke indawo. Kweli nqaku, siza kuphinda sizihlolisise ngokweenkcukacha i-pel, iintlobo zayo, iipropathi kunye neenkalo zesicelo.
1. UKWENZIWA KOKUGQIBELA
I-PE yindawo ye-thermoplastic ebizwa ngokuba yi-Ethylene Monologys yokuphendula kwePolymerisation. Kuxhomekeka kuxinzelelo kunye neemeko zeqondo lobushushu ngexesha lenkqubo ye-polymerisation, izixhobo ze-PE zinokuhlelwa zidweliswe kwiindidi ezininzi:
I-Polythylene (i-LDP): Olu hlobo lwezinto ze-PE lucwangciswe ngokukhululekileyo phakathi kweemolekyuli kwaye zisetyenziswe kakhulu kwimveliso yeefilimu zeplastiki, kwaye zisetyenziselwa iifilimu zezolimo .

I-Polythylene (i-HDPE): Iimolekyuli ze-hidpe zilungiswe ngokuqinileyo kwaye zibonisa ukuxinana okuphezulu, ngoko ke zibonisa amandla angcono kunye nokuxhathisa kwamandla kunye nokuchasana nemichiza.

I-Liner Prenity Polythylene (LDDP): I-LDDP): I-LDDE i-Polythylene ephantsi enesakhiwo esidibeneyo se-thythy sothy edibanisa ukuguquguquka kwe-LDPE. Iqhelekile isetyenziselwa ukwenza ifilimu, iingxowa zeplastiki kunye nezinto zokupakisha zemizi-mveliso.

2. Iimpawu eziphambili zezixhobo
Izinto ze-PE zinezinto ezininzi ezimangalisayo zomzimba kunye nekhemikhali ngenxa yesakhiwo sayo semolekyuli esahlukileyo, eyenza iphumelele uluhlu olubanzi lwezicelo:
Ukungaxhathisi iikhemikhali: I-PET i-PET ichaphazela kakhulu i-acids, ialkalis, iityuwa kunye nezinyibilikisi kubushushu begumbi, eyenza ilungele amashishini amachiza kunye namayeza.

Ukunganyangeki kakuhle kwempembelelo kunye namandla amanye: i-HDPE, ngokukodwa, inamandla aphezulu kunye nobungqingqwa kwaye inokumelana noxinzelelo lwendlela ephezulu, eyenza ukuba isetyenziswe ngokuqhelekileyo ukwenza imithwalo.

Iipropathi eziguquguqukayo ezilungileyo: I-PE STOSS i-insulator yombane ebalaseleyo, eyenza isetyenziswe ngokubanzi njengomlinganiso weentambo kunye neentambo.

Ukuthathwa kwamanzi asezantsi: I-PE Stowel inolufula amanzi aphantsi kakhulu kwaye ke ngoko igcina iipropathi zayo zokwenyama kwimimandla enomswakama.

I-3. Iindawo zesicelo kwizixhobo
Enkosi ngeendlela ezahlukeneyo kunye neepropathi ezigqwesileyo, izixhobo zidlala indima ebalulekileyo kubomi bemihla ngemihla kunye nomzi mveliso. Ukwazi ukuba zeziphi izinto ze-PE zisinceda ukuba siqonde ngcono uluhlu lwabo lwezicelo kwimimandla eyahlukeneyo:
Ishishini lokupakisha: Izixhobo zisetyenziswa ngokubanzi ekwenzeni iifilimu zeplastiki, iingxowa zephakheji zokutya kunye neefilimu zezolimo.

Umzi-mveliso wokwakha kunye ne-HDPE uhlala usetyenziswa kwimveliso yemibhobho yamanzi, imibhobho yegesi kunye nemibhobho yemichiza ngenxa yoxinzelelo olukhulu kunye nokunganyangeki.

Iimveliso zasekhaya: Iimveliso ezininzi zeplastiki zemihla ngemihla, ezinjengeebhakethi, iingxowa zenkunkuma kunye nezikhongozeli zokugcina ukutya, zenziwa kwi-polyethylene.

I-4. Ukukhuseleka kwendalo kunye nokurisayikilisha kwakhona kwezixhobo
Ngaphandle kwezibonelelo ezininzi, ukusetyenziswa ngokubanzi kwezixhobo ze-PE kuzise iingxaki zokusingqongileyo. Kuba ayinamsebenzi ngokulula, iimveliso ze-PE zisenokuba neempembelelo zexesha elide kwi-ecosystem. Izixhobo ze-Polythylene azisebenzi. Ngeendlela zomzimba okanye zekhemikhali, iimveliso ze-PE ze-PE zinokuchithwa zibe zizixhobo ezitsha, ngaloo ndlela zinciphisa ifuthe kwindalo esingqongileyo.
Ukuqukumbela
Ngolu hlaziyo lungentla, sinolwazi olucacileyo lombandela "Yintoni i-PE PAT". Njengesixhobo esibaluleke kakhulu seplastiki, iPolythylene isetyenziswa ngokubanzi kumashishini ahlukeneyo ngenxa yesakhiwo esikhethekileyo kunye nezinto ezibalaseleyo. Nangona isebenzisa imbiza imiceli mngeni engqongileyo, ulawulo oluzinzileyo lwezixhobo ze-PE lunokufezekiswa ngokurinta.
