Umgca wokuvelisa nokucola iibhotile zePET yiseti epheleleyo yezixhobo ezisebenza ngokuzenzekelayo ezicubungula iibhotile zePET ezilahliweyo (ezifana neebhotile zamanzi aneminerali, iibhotile zeziselo, njl.njl.) ngokuhlela, ukususa iileyibhile, ukutyumza, ukuhlamba, ukususa amanzi, ukomisa, kunye neenkqubo zokwahlulahlula ukuvelisa iiflekhi zePET ezicocekileyo. Ngumgca ophambili wemveliso yokuphinda usebenzise iiplastiki zePET.
Ukusetyenziswa Okuphambili kunye Nomthamo
• Ukusetyenziswa Okuphambili: Ivelisa ii-PET flakes ezicocekileyo kakhulu, ezinokusetyenziselwa ii-filaments ze-chemical fiber, izinto zokupakisha, amaphepha, njl.njl. Imigca yokutya ingasetyenziselwa ukuphinda isetyenziswe kwibhotile ibe yibhotile (ifuna i-FDA kunye nezinye iziqinisekiso).
• Umthamo oQhelekileyo: 500–6000 kg/h, onokuwuguqula ngokweemfuno, ufanelekile kwizityalo ezincinci ukuya kwezinkulu zokuphinda usebenzise.
Ukuhamba kweNkqubo ePhambili (Amanqanaba aPhambili)
1. Ukukhupha nokucwangcisa kwangaphambili: Ukukhupha izinto ezimdaka ngesandla/ngoomatshini (isinyithi, amatye, iibhotile ezingezizo ezePET, njl.njl.) ukuphucula ubunyulu bezinto eziluhlaza.
2. Ukususwa kweelebheli: Umatshini wokususa ilebheli wahlula umzimba webhotile yePET kwiilebheli zePP/PE; iilebheli zinokuphinda zisetyenziswe.
3. Ukutyumza: Isixhobo sokutyumza sinqumla iibhotile zePET zibe ziiflekhi eziyi-10–20 mm, kunye nesikrini esilawula ubukhulu.
4. Ukuhlamba kunye nokuHlela: Ukuhlamba okubandayo kwahlula iibhotile/iilebhile; ukuhlamba okune-friction kususa ioyile/izincamathelisi; ukuhlamba okushushu (70–80℃, ngesisombululo se-alkaline) kucoca kwaye kususe amabala aqinileyo; ukuhlamba kuphelisa kwaye kususe intsalela; ukuhlamba okunezigaba ezininzi kuqinisekisa ucoceko.
5. Ukucocwa nokuSomiswa: Ukucocwa kwe-centrifugal + ukomiswa komoya oshushu kunciphisa umxholo wokufuma kweeflekisi ukuya kwi-≤0.5%, nto leyo ehlangabezana neemfuno zokucubungula ezilandelayo.
6. Ukuhlela nokuPakisha kakuhle: Ukuhlela imibala/ukwahlulahlula ngobuninzi kususa iiflekhi eziguqulwe umbala, iPVC, njl.njl., kwaye ekugqibeleni iiflekhi ziyapakishwa kwaye zigcinwe.
• Izicelo: Izityalo zokuphinda usebenzise ii-PET, izityalo zefayibha yeekhemikhali, izityalo zezinto zokupakisha, amashishini okuphinda usebenzise izixhobo; iiflakes zingasetyenziselwa iifayibha zelaphu, ukupakisha ukutya (udidi lokutya), iiplastiki zobunjineli, njl.njl.
Izinto ekufuneka ziqwalaselwe xa ukhetha
• Ukuhambelana koMthamo: Khetha iinkcukacha zezixhobo ngokwemveliso elindelekileyo ukuze uphephe ukuchithwa kwamandla okanye ukungoneli kwamandla.
• Udidi lweMveliso eGqityiweyo: Udidi lokutya lufuna iinkqubo kunye nezixhobo ezicociweyo ngakumbi; udidi oluqhelekileyo lwemizi-mveliso lunokuba nolwakhiwo olulula.
• Inqanaba lokuZenzekela: Khetha umgca ozenzekelayo okanye ozenzekelayo ngokupheleleyo ngokusekelwe kwiindleko zomsebenzi kunye nobuchule bolawulo. • Ukusetyenziswa kwamandla kunye noKhuseleko lokusingqongileyo: Beka phambili izixhobo ezinokusetyenziswa kwamandla aphantsi kunye nobuchule bokuphinda usebenzise amanzi/ubushushu ukuze kuncitshiswe iindleko zokusebenza kunye nempembelelo yokusingqongileyo.
