Plashtiki yimaterelya singafumanayo kunesinye isikhundla sokugcina labantu abasebenzisa kulesi sizulu, njenge-amabhophothi wamanzi, amacantile nezintu zabantu. Yikho kakhulu! Wenza ukuthi uyayazi ukuthi plashtiki ungene emva kokuba kungenani elingana nesi- LDPE, okuthiwa ngokusho Low-Density Polyethylene? Plashtiki lesi sibuyiselwe sijikeleza, sisetshenziswa kunye nosizo. Sifuna ukusetshenziswa amagcino amabuyiselwe lama-LDPE lokuhlola ukuthi siyenza amanqaku amahlula amaphandle komhlaba kunye nokuthi sifundze uphelo.
Kunezinyathelo eziningi zokusetshenziswa kweGranules ezazibuyiselwa eLDPE. Yilo msebenzi okuyona ukuba sethe sifunda uphindo olufunekayo lapho silindele amanye amathuluzi nokuthi asihambisane ngazo. Lento ifanele ngoba imithwalo yephesi iyahamba ngomoya ofanayo ukusuka kwezikhali lokugcina. Njengemvume, lokhu kungabangela amakhulu! Leli ngenzelelo lisiza izinkunzi nokuthi akukho abantu abafumanekayo phesi elingezange lizama ukuphuma. Ngokushesha, umuntu ungakhipha ukuthi inkunzi incede phesi ngamashumi amabili! Lokhu kuhlela ukuthi sihlaleke amagama emfulweni ethile kanye nokuthola indlela yokubuyisela kweGranules eLDPE ngaphezu kwezinto ezintsha.
Ukusetshenziswa kwezinyathelo ezithunyelwe zomsebenzi wokuhlola (LDPE) lichasenqanawe lokugcina okukhulu. Ukusebenzisa uphawu olushesha olushintekayo kufanele lapho siphawula iplastiki entsha phakathi kwesicwangciso, lokhu kudinga imoya engakwazi ukubuyela ngempawu, ngokulandelayo umbuso wesintshabalalo nokuthi amagazini ahlola. Amagazi amaningi akalayishwa ngenkinga, kunye nokusetyenziswa kwazo kungavela ukuba kuhlupheka lokulandelana nesethombo. Ukuba siyilindelela izinyathelo ezithunyelwe zomsebenzi wokuhlola ezifanekiswe ngaphezulu kwezinto eziphumileyo, uzidinga umoya olucacileyo ukuze usetshenziswa amaninzi aphandle komoya okudingeka ukwenza amaninzi. Lokhu kungaba singahlinzekela ukusetshenziswa kokudla kumhlaba.
Kungakona ukuthi amagranulu ehlulekileyo lwe-LDPE kuyabheka izwe, kodwa bayabheka ngokubanjwa okulandelayo. Okuningi labantu baphumula ukuthi amathupha amahlulekileyo akukho inqanawa yetholeni yokugcina njengamathupha amahluwana, lokhu alikho kuhle. Njenge-mathupha amahluwana, amagranulu ehlulekileyo lwe-LDPE abaningi nge-srength ngesibhedlela esisodwa, ukuze umthakathi wokuhlanganiswa ubuyekezwe ngokubanjwa kungene nge-empahla enguqukene nokuthi uyinkantolo. Loko kungaba uyayazi ukuthi umthakathi weplasitihesi wesikhatsi sokuhluleka kufuneka lebe ngokubanjwa ngokupheleleyo njengalokhu elingezansi.
Ngenkathi ufundzisi olukhethwe ukuphatha amanqaku amaphlastik ngokuthi ubheke phakathi kwebesiphi esifumanekayo, ufuna ukuba ukhetha amagranulu eziyindwendwe ezilungiselelweyo kwiLDPE. Uhlobo lweGranulu leLDPE elungiselelweyo Ngaphambi kokuthi ucinge ukunyakathisela amagranulu eziyindwendwe ezilungiselelweyo, bheka ukuthi amagranulu apha angaba okuncane ngeuhlangothi. Njengemali engahlukile, amanye amathetho akavunyelwa njengoba angamukelwa ngendlela enenye kwaye angabonisa izinkinga zokusukela. Ufunda imininingwane yedate ngamva kwemvula we-2023. Amagranulu azotestiswa ukubheka ukuthi amagranulu angaba amanqaku ukusetyenziswa kunye nokuba amasafeku kusetshenziswa.
Lokho kulomgca olunye oluneminyaka engaze ukwenzela ukusiza i-Lethu lakho ngekhatsi le-LDPE elibuyiselwe. Ukusendzisana kuhle kungaba ukukhetha ngaphakathi kwesikhathu esizohlala sasentsha. Amamaterial angelihle ahluleka ukubuyiselwa ukuze azifise izincedo, aziphindvuke umoya, kunye nokufika amandla kunye nokuphucumana. Ukuthi uzofika ezi-10 ezitoni zezigcino elibuyiselwe lama-LDPE lokusebenza plashtiki ku-Yuezheng, sithetha ngokulandelana nesendzisano. Sicenza ukuthi ngezinto zakho uzohamba ngenkxaso okuningi lokuziphatha isikhathu sesitshebele.
