Ngaphambi kweiphepha ikomityi izinto ekrwadazenziwe kwiikomityi zephepha, uluhlu lwengubo luya kusetyenziswa kwiphepha lesiseko, ukwenzela ukuba iikomityi zephepha zikwazi ukubamba ulwelo kunye nezinye iziphuzo.

Iingubo zekomityi yephepha zinokwenziwa kwiindidi ezahlukeneyo zeplastiki, kwaye iikomityi zephepha zinokuveliswa ngaphandle kokwaleka ngeplastiki.Ngoko ke yintoni umahluko phakathi kweentlobo ezahlukeneyo zokugquma?Namhlanje ndiza kukwazisa.

I-PE igqunywe ngekomityi yephepha

Ukuze wenze iikomityi zephepha zingabi namanzi, ngaphakathi kweekomityi zephepha ziya kugqunywa ngefilimu encinci.Iikomityi zeplastiki ezigqunywe ngeplastiki zigqunywe ngepeyinti yepeyinti.I-PE yokugqoka i-coat-grade-grade coating enokuthi idibane nokutya.Ayinabala, ayinavumba, ayinabungozi bokutya, eyenziwe nge-naphtha, kwaye ayinakuthotywa ngokwendalo.

I-PLA indebe yephepha - i-bioplastic

Iikomityi zephepha ze-PLA, njengezinyeiikomityi zephepha, inomaleko obhityileyo weplastiki yokugquma ngaphakathi, kodwa xa kuthelekiswa nezinye iikomityi zephepha ezigqunywe ngeplastiki ezingaboliyo, iPLA eyenziwe ngezinto zezityalo ezifana neswekile, i-cornstarch, imoba okanye iibeet zeswekile, Yi-bioplastic ye-biodegradable.

I-PLA ineqondo eliphantsi lokunyibilika, ngoko ke ilungile kwiziselo ezibandayo ezingekho shushu kune-40 degrees celsius.Apho kufuneka ukuxhathisa ubushushu ngakumbi, njengakwi-cutlery, okanye iziciko zekofu.Oku kubandakanya ukongeza itshoki kwi-PLA ukuze isebenze njenge-catalyst, kwaye emva koko ifudumeze ngokukhawuleza kwaye ipholise i-resin ye-PLA ngexesha lemveliso.

Iimveliso ze-PLA zithatha iinyanga ezi-3-6 ukwenza umgquba kwiziko lenkqubo yokwenziwa komgquba kwimizi-mveliso.Ukuveliswa kwe-PLA kusebenzisa i-68% ngaphantsi kwemithombo ye-fossil ye-fossil kuneeplastiki eziqhelekileyo kwaye yi-polymer yokuqala ye-greenhouse gas engathathi hlangothi yehlabathi.
Ulwazi malunga neekomityi zephepha luya kuchazwa apha.Ukuba ufuna ukwazi ngakumbi malunga neekomityi zephepha, wamkelekile ukuba ucofe apha ukukuzisela amanqaku amnandi ngakumbi.
