Ungcoliseko lweplastiki lube ngumba ocinezelayo wehlabathi jikelele, kunye nezigidi zeetoni zenkunkuma yeplastiki ephela kulwandle lwethu, kwiindawo zokulahla inkunkuma, nakwiindawo ezisingqongileyo zendalo minyaka le.Ukujongana nale ngxaki kufuna izisombululo ezitsha, kwaye esinye isisombululo esinjalo ngumgca wokuhlambulula iPPPE.
Umgca wokuhlaziywa kwe-PP PE yinkqubo ebanzi eyenzelwe ukuphinda isetyenziswe kwaye iphinde isebenzise izinto zeplastiki zasemva kwabathengi, ngokukodwa i-polypropylene (PP) kunye ne-polyethylene (PE).Ezi ntlobo zeplastiki ziqhele ukusetyenziswa ekupakishweni, iibhotile, kunye neemveliso ezahlukeneyo zabathengi, nto leyo ezenza zibe negalelo elikhulu kwinkunkuma yeplastiki.
Umgca wokurisayikilisha uquka amacandelo amaninzi angundoqo asebenza ngokuhambelanayo ukusetyenzwa nokuguqula inkunkuma yeplastiki ibe yimathiriyeli enokuphinda isetyenziswe.Inyathelo lokuqala libandakanya indlela yokuhlela eyahlula iindidi ezahlukeneyo zeeplastiki ngokusekwe kubume nombala wazo.Oku kuqinisekisa i-homogeneous feedstock kumanqanaba alandelayo enkqubo yokurisayikilisha.
Emva koko, inkunkuma yeplastiki iphantsi kwenkqubo yokuhlamba ngokucokisekileyo.Oku kubandakanya uthotho lwamanyathelo okucoca, anjengokuhlamba i-friction, ukuhlamba amanzi ashushu, kunye nokucocwa kweekhemikhali, ukususa izinto ezingcolisayo ezifana nobumdaka, iilebhile kunye nezinto ezincamathelayo.Inkqubo yokuhlamba idlala indima ebalulekileyo ekuveliseni imathiriyeli yeplastiki esetyenzisiweyo ekumgangatho ophezulu.
Yakuba icociwe, inkunkuma yeplastiki iculwa ngoomatshini ibe ngamaqhekeza amancinci emva koko igqitywe kuluhlu lwezixhobo, kubandakanywa igranulator, iwasha yefriction, kunye necentrifugal dryer.Aba matshini banceda ukuphula iplastiki ibe yigranules kwaye basuse ukufuma okugqithisileyo, belungiselela izinto ezikwinqanaba lokugqibela lomgca wokurisayikilisha.
Iplastiki yegranulated ithi ke inyibilikiswe kwaye ikhutshelwe kwiipellets ezifanayo, ezinokuthi zisetyenziswe njengemathiriyeli ekrwada kumashishini ahlukeneyo.Ezi pellets ziphinda zisetyenziswe zineempawu ezifana neplastiki enyulu, ezenza zilungele ukwenza iimveliso ezintsha ezifana nezikhongozeli zeplastiki, imibhobho, kunye nezinto zokupakisha.
Iinzuzo zokusebenzisa umgca wokuhlambulula i-PPPE zininzi.Okokuqala, inciphisa kakhulu ubungakanani benkunkuma yeplastiki ephela kwindawo yokulahla inkunkuma okanye ingcolise indawo esingqongileyo.Ngokuphinda sisebenzise imathiriyeli yeplastiki, sinokugcina izixhobo ezixabisekileyo kwaye sinciphise imfuno yemveliso yeplastiki entsha.
Ngaphezu koko, ukusetyenziswa kweplastiki esetyenzisiweyo kunciphisa ukukhutshwa kwekhabhoni kunye nokusetyenziswa kwamandla okuhambelana neenkqubo zokuvelisa.Ukurisayikilishwa kweplastiki kufuna amandla amancinane kunokuvelisa iplastiki enyulu kumafutha efosili, okokufaka igalelo kwindlela ezinzileyo nengasingqongileyo.
Ngaphezu koko, umgca wokuhlaziywa kwe-PPPE unceda ekudaleni uqoqosho lwesetyhula yeplastiki, apho izixhobo ziphinda zisetyenziswe kwaye ziphinde zisetyenziswe endaweni yokulahlwa.Oku kunciphisa imfuno yemveliso yeplastiki entsha, igcina izixhobo, kwaye inciphisa impembelelo engalunganga yenkunkuma yeplastiki kwizinto eziphilayo.
Ukuqukumbela, umgca wokuhlambulula i-PPPE ubonelela ngesisombululo esisebenzayo sokujongana nengxaki yehlabathi jikelele yenkunkuma yeplastiki.Ngokuphumeza le nkqubo ibanzi yokuphinda isetyenziswe, siyakwazi ukuguqula inkunkuma yeplastiki yasemva kwabathengi ibe yimithombo exabisekileyo, sinciphise ukungcoliseka kwendalo, kwaye sikhuthaze indlela ezinzileyo yokusetyenziswa kweplastiki.Ukwamkela obu bugcisa bokurisayikilisha kubalulekile kwikamva elicocekileyo neliluhlaza.
