Ngokuqhubela phambili kwetekhnoloji kunye nokunyuka kwemidlalo yangaphandle,iitafile ezisongwayo zeplastikingokuthe ngcembe ziye zabonakala emehlweni abantu.Iphumelele inkoliseko yabantu ngomthamo wayo omncinci kakhulu, ubunzima obulula kunye nokusetyenziswa okufanelekileyo emva kokusonga.Itheyibhile yokusonga yenziwe ngephaneli kunye nesakhelo.Namhlanje ndiza kuzisa izinto zetafile yokusonga.
I-polyethylene ephezulu (i-HDPE), i-powder emhlophe okanye imveliso yegranular.I-non-toxic, incasa, icrystallinity ye-80% ukuya kwi-90%, indawo yokuthambisa ye-125 ukuya kwi-135 ° C, ubushushu benkonzo ukuya kwi-100 ° C;
ukuqina, amandla okuqina kunye nokurhubuluza kungcono kune-polyethylene yoxinaniso oluphantsi;
Ukumelana nokunxiba, umbane Ukugquma okulungileyo, ukuqina kunye nokumelana nokubanda;
ukuzinza kakuhle kweekhemikhali, ezingenakunyibilika kuyo nayiphi na i-solvents ye-organic kwiqondo lokushisa, i-corrosion ukumelana ne-acids, i-alkali kunye neetyuwa ezahlukeneyo;
ifilimu ine-permeability ephantsi kumphunga wamanzi kunye nomoya, kunye nokufunxa kwamanzi okuphantsi;
ukunganyangeki ukwaluphala, ukumelana noxinzelelo lokusingqongileyo alulunganga njenge-polyethylene yoxinaniso oluphantsi, ngakumbi i-oxidation ye-thermal iya kunciphisa ukusebenza kwayo,
ngoko ke i-antioxidants kunye ne-ultraviolet absorbers kufuneka yongezwe kwi-resin ukuphucula le ntsilelo.
Ifilimu ye-polyethylene ene-high-density ineqondo lokushisa eliphantsi lokuphazamisa ukushisa phantsi koxinzelelo, ngoko kufuneka kuthathelwe ingqalelo xa uyisebenzisa.
Kule nkulungwane, inkqubela yenguqu yenzeke kwintsimi yeepayipi, oko kukuthi, "ukutshintsha intsimbi ngeplastiki".Ngenkqubela phambili ekhawulezileyo yesayensi yezinto zepolymer kunye nobuchwepheshe, ukujula kophuhliso kunye nokusetyenziswa kwemibhobho yeplastiki, kunye nokuphuculwa okuqhubekayo kobugcisa bokuvelisa, imibhobho yeplastiki ibonise ngokupheleleyo ukusebenza kwayo okugqwesileyo.
Namhlanje, imibhobho yeplastiki ayisaphazami “njengeendawo ezingabizi kakhulu” zemibhobho yentsimbi.Kulo tshintsho, iipayipi ze-polyethylene zithandwa kwaye ziya zikhanya ngokukhanyayo.Zisetyenziswa ngokubanzi kuthumelo lwegesi, unikezelo lwamanzi, ukukhutshwa kwelindle, ukunkcenkceshela kwezolimo, uthutho oluluqilima kwimigodi, kunye nemimandla yeoli, iikhemikhali, iposi kunye nonxibelelwano, njl. uthutho lwegesi.
