Umatshini wokurisayikilisha wePlastiki wefilimu yenkunkuma yeHDPE(ifilimu yokwahlula ibhetri yelithiyam)
Umatshini wePlastiki wokuRisayikilishwa kwifilimu yenkunkuma yeHDPE(ifilimu yokwahlula ibhetri yelithium)
Kwinkqubo yokuvelisa i-lithium ibhetri ye-separator nge-hydrometallurgy, inani elikhulu lezinto ezinqamlekileyo (i-HDPE i-ultra-high molecular weight polyethylene) iya kuveliswa.Ezi offcut (ifilimu yenkunkuma ye-HDPE) inokuphinda isetyenziswe kwimibhobho, iiplastiki ezilungisiweyo kunye nezinye iimveliso, ezinexabiso eliphezulu lokusetyenziswa.Ngethuba lokuqhutyelwa kwezi mveliso, izinto ezinqamlekileyo ziya kuhlanjululwa ngaphambi kokusetyenziswa.Ngenxa yezinga eliphantsi lokunyibilika kwe-UHMWPE okanye i-UHMWPE, ukuqhutyelwa kwe-extrusion kunzima.I-PURUI ibonelela ngendlela entsha yokuthotywa kunye nokubuyisela inkunkuma ye-ultra-high okanye i-ultra-high molecular weight polyethylene.Le ndlela inenkqubo elula yokubuyisela, enokuthi isetyenziswe ukuthobisa kunye nokubuyisela i-polyethylene ephezulu-phezulu okanye i-ultra-high molecular weight polyethylene ngendlela ehambelana nokusingqongileyo kunye nefanelekileyo, okwenza inkunkuma ye-polyethylene emva kokuthotywa ibe nokuqhubekeka kakuhle, ngaloo ndlela iqonda ukurisayikilishwa kwe-offcut. izixhobo, ezineenzuzo ezilungileyo kwezoqoqosho.
Umgca wokurisayikilishwa kweplastikikukwaphula ikhonkco lemolekyuli ye-ultra-high okanye i-ultra-high molecular weight polyethylene (UHMWPE) ngokuyityumza ifilimu (okt into eshiyekileyo equlethe i-ultra-high okanye i-ultra-high molecular weight polyethylene) kwaye emva koko uyityise kwi-extruder, kunye emva koko unyibilike u-extruding phantsi kobushushu obuthile obuphezulu kunye nesenzo sokucheba sesikrufu se-extruder, ukuze ikhonkco lemolekyuli ye-UHMWPE okanye i-polyethylene ephezulu kakhulu yemolekyuli inokwaphulwa, ngaloo ndlela ibenobushushu obuphezulu bokucheba ubumanzi kunye nokucubungula lula, ukuqonda ukubuyiswa kobutyebi kunye nokusetyenziswa kwakhona. , kunye nokugcina iindleko zeshishini.

Inkqubo elula, ixabiso eliphantsi
I-PUUI'sumgca wegranulationinokuqonda ukugaywa ngokutsha kwezinto ezilahlwayo ze-ultra-high okanye i-ultra-high molecular weight polyethylene, okt i-offcut, kunye nokuzisebenzisela ngokuthe ngqo ukusetyenzwa kwemibhobho esezantsi, iiplastiki ezilungisiweyo kunye nezinye iimveliso, ukusombulula ingxaki yokucubungula ubunzima ngeendlela zemveli;Ukongezelela, akukho nxalenye yeekhemikhali eyongeziweyo ngexesha lokuphinda isetyenziswe / inkqubo ye-granulating, engayi kubangela ukungcola okwesibini kwaye iya kuba nobungane bendalo;Kuya kuphunyezwa ukurisayikilishwa kwemithombo yenkunkuma, konga iindleko kwaye kuneenzuzo ezinkulu kwezoqoqosho.
Isixhobo se-granulation kunye nendlela yokubuyisela eyilwe ngu-PURUI ngokufanelekileyo ukuthotywa kunye nokubuyisela i-UHMWPE.Izinto eziphathekayo zinokunyibilika kwaye zihambe, kwaye zinokuphinda zenziwe igranulated.Izinto eziphathekayo zinamandla amakhulu omatshini.
Umatshini wokurisayikilisha weplastiki luhlobo lwezixhobo ezisetyenziselwa ukusetyenzwa ngokutsha kwenkunkuma yeplastiki kwiigranuli okanye iipeliti ezinokuthi ziphinde zisetyenziswe ekwenzeni iimveliso zeplastiki ezintsha.Umatshini usebenza ngokucofa okanye ukucola inkunkuma yeplastiki ibe ngamaqhekeza amancinci, emva koko uyinyibilikise kwaye uyikhuphe ngokufa ukwenza iipellets okanye iigranules.
Kukho iintlobo ezahlukeneyo zeplastiki zokurisayikilisha kunye noomatshini begranulating abakhoyo, kubandakanywa isikrufu esinye kunye ne-twin-screw extruders.Abanye oomatshini baquka iimpawu ezongezelelweyo ezifana nezikrini zokususa ukungcola kwinkunkuma yeplastiki okanye iinkqubo zokupholisa ukuqinisekisa ukuba iipelisi ziqiniswe ngokufanelekileyo.Umatshini wokuhlamba ibhotile ye-PET, i-PP elukiweyo yeengxowa zomgca wokuhlamba
Oomatshini beplastiki bokurisayikilisha kunye noomatshini bokwenza igranulayitha baqhele ukusetyenziswa kwimizi-mveliso eyenza isixa esikhulu senkunkuma yeplastiki, njengokupakishwa, iimoto kunye nokwakha.Ngokuphinda kusetyenziswe inkunkuma yeplastiki, aba matshini banceda ukunciphisa impembelelo yokusingqongileyo yokulahlwa kweplastiki kunye nokugcina izixhobo ngokusebenzisa izinto ebezinokulahlwa ngenye indlela.
Isixhobo sokurisayikilisha ibhetri yeLithium luhlobo lwezixhobo ezisetyenziselwa ukurisayikilisha nokubuyisela izinto ezixabisekileyo kwiibhetri ze-lithium-ion, eziqhele ukusetyenziswa kwizixhobo zombane ezifana nee-smartphones, iilaptops, kunye nezithuthi zombane.Isixhobo sisebenza ngokuqhekeza iibhetri kwiindawo zazo, njenge-cathode kunye nemathiriyeli ye-anode, isisombululo se-electrolyte, kunye neefoyile zetsimbi, kwaye emva koko zahlula kwaye zihlambulule ezi mathiriyeli ukuze zisetyenziswe kwakhona.
Kukho iintlobo ezahlukeneyo zezixhobo zokuhlaziya ibhetri ye-lithium ezikhoyo, kubandakanywa iinkqubo ze-pyrometallurgical, iinkqubo ze-hydrometallurgical, kunye neenkqubo zoomatshini.Iinkqubo zePyrometallurgical zibandakanya ukusetyenzwa kobushushu obuphezulu beebhetri ukubuyisela iintsimbi ezinje ngobhedu, nickel, kunye necobalt.Iinkqubo ze-Hydrometallurgical zisebenzisa izisombululo zekhemikhali ukunyibilikisa amacandelo ebhetri kunye nokubuyisela iintsimbi, ngelixa iinkqubo zoomatshini zibandakanya ukuqhekeza kunye nokugaya iibhetri ukwahlula izixhobo.
Isixhobo sokurisayikilisha ibhetri yeLithium sibalulekile ekunciphiseni impembelelo yokusingqongileyo yokulahlwa kwebhetri kunye nokugcina izixhobo ngokufumana kwakhona iintsimbi ezixabisekileyo kunye nezinto ezinokuthi ziphinde zisetyenziswe kwiibhetri ezintsha okanye ezinye iimveliso.
Ukongeza kwiinzuzo zokusingqongileyo kunye nokugcinwa kwezibonelelo, izixhobo zokuphinda zisetyenziswe ibhetri ye-lithium nazo zineenzuzo zoqoqosho.Ukufumana kwakhona isinyithi esixabisekileyo kunye nezinto ezivela kwiibhetri ezisetyenzisiweyo kunokunciphisa iindleko zokuvelisa iibhetri ezintsha, kunye nokudala imithombo emitsha yengeniso kwiinkampani ezibandakanyekayo kwinkqubo yokubuyisela kwakhona.
Ngaphaya koko, ukwanda kwemfuno yezithuthi zombane kunye nezinye izixhobo zombane kuqhuba imfuneko yoshishino olusebenzayo noluzinzileyo lokurisayikilisha kweebhetri.Isixhobo sokurisayikilisha ibhetri yeLithium singanceda ukuhlangabezana nale mfuno ngokubonelela ngendlela ethembekileyo nengabiziyo yokufumana kwakhona imathiriyeli exabisekileyo kwiibhetri ezisetyenzisiweyo.
Nangona kunjalo, kubalulekile ukuqaphela ukuba ukwenziwa kwakhona kwebhetri ye-lithium kuseyishishini elitsha noko, kwaye kukho imiceli mngeni ekufuneka yoyiswe malunga nokuphuhlisa iinkqubo zokurisayikilisha ezisebenzayo nezingabizi kakhulu.Ukongeza, ukuphathwa ngokufanelekileyo kunye nokulahlwa kwenkunkuma yebhetri kubalulekile ukuphepha iingozi zendalo kunye nempilo.Ngoko ke, imimiselo efanelekileyo kunye namanyathelo okhuseleko kufuneka abekhona ukuze kuqinisekiswe ukuphathwa ngokufanelekileyo kunye nokuhlaziywa kweebhetri ze-lithium.
