Ukuba udibanise ngasho, ukuthi zingapi imibhi yezilondolozi ezinjalo zihlabeleka? Ngenxa yalokho, umthombo weplastiki olusetyenziswa ukwenza lezi zinto kukhona kakhulu kwindawo elithile. Amaplastiki angalinye inani lakho lendlu, lokho kufanele ukubonele ukuba zizo zintsuku ezininzi ezifanele. Amagranuli eziqephu ze-LDPE nguwo wemibhemi eminingi eyenziwayo ngemibhemi engaphezulu kwezintloko. Amagranuli eziqephu ze-LDPE ezinhloniphe ngokubanzi babonakale ukuba bayenziwe ngendlela engekho noma endaweni elingena.
UKholwa okuncane kwe-LDPE kukho Low-Density Polyethylene. Yinkxaso elithile yomthetho wokuphakamisana ngeplastikhi esiqinisekisiyo. Ngokubanzi, i-LDPE ingaphesheya - yokugqibela ukuthi inakho umoya omphini okanye uphawu olungaphansi obunene ngokushintsha ngaphandle kokucabanga. Kwiimeko eziningi, le phesha yinhloko. Ngenxa yalokho, ukuhlaba lokulandelana nalo luhlinzekelayo kunjalo kakhulu ngokusebenzisa. Ukufakelwa kwakhe kumngangathu kunye nezinye izinto zokusebenza ukuba zityenziswa ngokubonakale. Ngokwesikhatsi sokuqaleni, i-LDPE iyityenziswa kwiqinisekiso lokuhlola imibiko eneenkinga lokhu kanye nokuthi amaqembu angaphezu kwaloo mthetho apho siyaziyo: amabhedi amaphlastiki, ibhotili, utyubha, kunye namanye amaxwebhu osekuseni asetyenziswa ngazo.
Izinyawo ezinomnyama ze-LDPE zilungelamashumi ngokubanzi ukuthi zingaphambili. LEDE ingaphambili kakhulu kunoma iziplastiki eziningi. Lokhu kulandelayo ukusukela imali futhi ukusiza amakhiwo okusebenza, okuningi lapho. Zizoshintshwa ngasemva kwezindlela ezininzi ngokushesha ukuze bengako amaqanda amabhedlela. Ukuphakamisana kwazo kuzofunyanwa ngokuthi zikhona kwisebe esiqinisekileyo, njengesi injection molding, okufunyanwa ukwenzela ukuhlola kakhulu nokugcina umnotho wokuqala.
Izinyawo ezinomnyama ze-LDPE zihlaba indlela elungileyo lokuhlula. Lokhu kusetshentela ukuthi zikululekile kumazwi, amanqaku nemibhalo apha apho azobhekisele ngasemva kwezindlela. Lendlela lokuhlula lokuhle libheka ukuphakamiswa, uzokusindiswa ngeprodukte ngaphakathi. Ngakho ke, izinyawo ezinomnyama ze-LDPE zihlaba uphelo olungileyo olungaphandle kwe-UV rays ye-sun. Oku kusetshentela ukuthi zikhona kusebenzisi phandle komkhaya, apho angasebenzi kakhulu ngokubheka emanzini ngenxa yomoya ongaphandle.
Ngokushesha kakhulu ngeflexibility noma umnotho wabo, amagranule angamnyama a-LDPE zisebenzeka ngakubalwa kuhlukelelo lokusebenza noma lokusetyenziswa. Umbhali wemibhali yomphako yisigaba esincane elifunyenweyo ezinikezela kwezi granule zomnyama ze-LDPE. I-tote bag iyinhle, isebenza kunye neyiphi lexi-flexible ngakwesobizo sokuqala sokuthi siyilandelani ekupheleni lwenyumbu/lwendaweni yokugcina okanye emikhambi. Okukho kunezinye izinto eziphathelene ngoba zingabizwa ukuthi zingazibulala izinto neminyaka engaphezulu.
Amagranule angamnyama a-LDPE azisebenzeka futhi ukusetshenziswa komphakathi, njenge-tubing, pipes, nokhophu lekilekile, ngakwesobizo sombali wesintshanti. Izinhlobo eziningi zithetha imithombo eyahlukileyo ukuze zihlale khona ngendlela efanele ngaphandle kokuhlukana nokuphucukeleka kumakhemikali. LEPE inhlawuleke kakhulu kumakhemikali kunye nokuba asiphumeleleyo kakhulu lokusebenza kakhulu, ngakwesobizo sithi siyilokhu sikhethiwe.
Amagranuli eziqephu ze-LDPE zikhululekile kakhulu ngemibhemi engaphezulu kwezinto ezinamandla nokusetyenziswa, njengomphakathi wokugcina ngezintloko, lokho kufanele ukubonele ukuba kuzo zintsuku ezininzi ezishona. Izinkambu ze-LDPE zisebenziswa ngabanye abahlali besebenza ukuvavanya izincinci zakhe ukungabikwe yezimvula. Ukusetshenziswa kwe-LDPE ekuseni lwesayensi luhluke amanani aphantsi kunye nokuthola ukuphucumana kwizindlela ezindala. Inkonzo yokusebenza ye-LDPE yasetyenziswa ngaphakathi komhlaba, ukusukumisa ukuthi izinto zingakwazi ukubuyela phakathi komhlaba. Ngakho ke, i-LDPE isetshenziswa ngakho kakhulu kwiimpahla yomsindo, ukuze kube ngoku kuneentsha.
