12 Febhuwari 2020 Yini ngokuthi i-Polyethylene LDPE? Yingxenye yephesi elinikazi kakhulu kwiimbali ezininzi ezinikezeliyo. Le phesi ifanele kwiyo ngokuphi na kwiyo kwiimbali ethilethi kanye neziyethente zethule ekuseni. Lendawo lethe kulandelayo lizohlola okuningi nge-LDPE polyethylene ngokusebenzisa amathathu amahlanu.
i-LDPE: i-Polyethylene yase-LDPE iyikohi kakhulu ukuba ingqanqane kancinci kodwa incinci kunye nesibhedlela esisodwa. Oku kuvunyelisa ukuba ingqanqane kunye nokuhamba ngokubhalekelayo ngaphandle kokugcwaliswa. Isipho esikhoyo esidingekayo nge-LDPE ngoku uthi uqondile kumthetho ophansi lokuluma, lufuneka ulayishwe, alungiselelwe, kunye nokuyibhizwa ngamabhaba angahlukene. U-LDPE akwaziwa ngeminyaka engaphezulu, kunesi-sihlalo somkhuhlane somncinci, amabhopho abamalunga nobhopho besebenza ukuphakamisa imifuno kunye nezilungu ezinamandla zokuphakamisa izinkomo zomoya kunye nemibhobho ebhalulekileyo. Kunezinto ezininzi ezimelwe ngemithombo ka-LDPE ngokusebenzela ukubhekana phakathi komkhaya wakho. Ngokushesha kakhulu, abantu abaningi abangena apho!
I-Polyethylene LDPE iyaphuthintisa izindawo zokuphakamisa nokusebenzela kwezindlela ezinhle. Ukhombisano lwakhe lwe-flexibility nesibhedlela sikhulula ukuba kuyimvelo yokusebenzela iindlela eziqhelekileyo. Ngokubanzi, u-LDPE usebenzisa kuhlanganiswa komoya amaphayiphi, amathambo ase-gym esithathe abantu abafitini ngaphandle kokubhujabha kunye nezinto ezinikezeli lokusebenza ekhaya apho bantfu babasebenza. U-LDPE uyinqanawa kakhulu ngakho ingasusi ukusuka, ukuze kube ngokuqinile yicala lokutshebeleka. Lokhu lihluke kakhulu lokunqume ukukhokha amagama, okungcono emisebenzini ebenza ukwenzela ukufinyelela imali. Lolu hlobo lokuhlola kulula phambi kokuthi amaxesha akhetha ukwenza imali. Ngakho langakho, i-LDPE lingalimi eliphakamile, ubonakale ukuba lingaqinisekiswe kunye nokuba lingezwe ngendlela ye-new products. Ngokwesibonelo sokuqinisekisa, baye bazihlonipha indlela yesiphumo sokuthi bangene ngokushesha ukususa umlayo kunye nokuthuthukisa izinhlobo ezinomsindo.
Kulokho kungakwazi ukuba kuna amasiko esibuyisayo kunye nezikhankiso ezidinga ukusuka kwe-LDPE polyethylene yezilimi. Izinkinga eziqondileyo lwe-LDPE ngokusho ukuba inakhiwo. Yinto engcono, uma isiphumo sikhulu, siyakwazi ukuhlanganisa lokhu ngeemvelo etsha njengamabhenkisi emiparkini kunye nokuthi okuningi olunikezelwe ngokubheka phandle. Ngoba LESI i-LDPE iyinye yenkululeko, iziphumo ziyahlala kakhulu ukuthi zihlalele ngokuphumeleyo ukuthi zifundise imoya yokusebenza ukuthi zitshale. Lokhu kuhlanganisa nokugcina ukufumanisa umoya wethu wesintshontsho, okungakuhlukwe ngendlela enkulu yokuthola indawo yethegi. Ngakho ke, we-LDPE wenakho amandla amaningi yakhe. Isidingo esidingayo yona kukuba ayinakho ukwenqaniswa kwesithathu. Ukuthi ngokwesobizo, akavumelana ngeentemba enkulu. We-LDPE awunakho ukubhedelela, okungena ukuthi angakade ahlaleke ngokubhekisisa kwindawo yokudibanisa. Amapheli amaningi amadliwa ngokuthi kuhlanganise ukubheka kokuthi amanye amathari amaningi angazama ukuthola entemba enkulu kunye nokubhedelela.
I-polyethylene LDPE isebenzisa indlela eyaziwa ngokuthi i-polymerization. Leli yigama elide elisitshela ukuthi le nto yenziwe ngani. Kule nqubo, kufudunyezwa igesi ebizwa ngokuthi i-ethylene bese ifakwa ngaphansi kwengcindezi. Lapho lokho kwenzeka, kwakha amaketanga amade ama-molecule abizwa ngokuthi ama-polymer. La ma-polymer abese epholile abe yipulasitiki esiyiqaphela ngokuthi i-LDPE. Ngenxa yokuthi i-LDPE iqukethe izinsalela eziguquguqukayo nezigxilile ekwakhekeni kwayo kwamakhemikhali, ibonakala ngokuqina okuphezulu kanye nephuzu lokuncibilika eliphansi. Enye inzuzo enhle yokukhiqiza i-LDPE ukuthi inqubo yokwakha i-LDPE ingenawo amandla amaningi. Akudingi ukushisa noma ingcindezi eningi, okwenza kube impahla eshibhile ukuyenza. Kuwumkhiqizo ongabizi kodwa omuhle futhi owusizo ezinkampanini.
Ukufika kwezinto ezinhle kwi-polyethylene LDPE kuzo zindlela ezintsha nezingeni lokusebenza. Ngokushesha, amafirma yokugcina okuguqulwa khetha ukusetyenziswa kwe-LDPE kumithombe yokuqophela. Lokunye umphako wakho, ngaphakathi kwabantu abangamashumi amabili latex imithombo yakhe ayiqhathanisekanga, ngakho ke i-LDPE inokwsebenzisa ukwenza lo. Ukusetshenziswa kwe-LDPE kunokuba kuhlukelelwa ukuze kusetshenziswa izinto zokuthenga ezi-3D. Lolu hlobo lokungena le-LDPE lichasene nesikhatsi esisodwa sokuthi sibonisa ukuthi sifunda ukubuyela nokuthi sihlale kakhulu kanye nezindaba eziningi.
