Pankhani yamakanema apulasitiki, pali njira ziwiri zodziwika pamsika:Zithunzi za HDPE(Polyethylene Yapamwamba Kwambiri) ndiLDPE(Polyethylene yotsika kwambiri).Zida zonsezi zimagwiritsidwa ntchito kwambiri m'mafakitale onyamula katundu, ulimi, ndi zomangamanga.Komabe, ogula ambiri ndi mabizinesi nthawi zambiri amadabwa chomwe chili bwino pakati pa HDPE ndi LDPE.M'nkhaniyi, tiwona kusiyana pakati pa zipangizo ziwirizi ndikukambirana ubwino ndi zovuta zake.
Choyamba, tiyeni tiwone LDPE.LDPE ndi chinthu chosinthika komanso chopepuka chomwe chimagwiritsidwa ntchito kwambiri popanga mafilimu apulasitiki owonda komanso otambasuka.LDPE imagwiritsidwa ntchito nthawi zambiri pakuyika, monga kupanga matumba apulasitiki, zomangira zocheperako, ndi mafilimu aulimi.LDPE imadziwika chifukwa chokana kwambiri chinyezi ndi mankhwala, ndikupangitsa kuti ikhale yoyenera kugwiritsa ntchito zomwe zimafuna kusinthasintha kwakukulu komanso kukhazikika.Opanga mafilimu a LDPE nthawi zambiri amapanga zinthu zosiyanasiyana kuti akwaniritse zosowa zosiyanasiyana za makasitomala awo.
Kumbali ina, HDPE ndi yolimba komanso yamphamvu poyerekeza ndi LDPE.HDPE imagwiritsidwa ntchito kwambiri pamapulogalamu omwe amafunikira mafilimu apulasitiki olimba komanso olimba, monga kupanga zikwama zolemetsa, ma tarpaulins, ndi ma liner a mafakitale.Kanema wa pulasitiki wa HDPEimadziwika chifukwa cha mphamvu zake zolimba komanso kukana mankhwala, zomwe zimapangitsa kukhala chisankho choyenera pa ntchito zakunja ndi zolemetsa.Opanga mafilimu a HDPEkupanga zinthu zambiri zomwe zimagwira ntchito zamafakitale ndi zamalonda.
Tsopano, tiyeni tifanizire zida ziwirizo malinga ndi momwe zimakhalira komanso mawonekedwe awo.LDPE imadziwika chifukwa cha kusinthasintha kwake komanso kusinthasintha, komwe kumapangitsa kuti ikhale yoyenera kugwiritsa ntchito zomwe zimafuna kutambasula komanso kufananiza ndi zinthu zomwe zikupakidwa.Kumbali inayi, HDPE imadziwika chifukwa cha kuuma kwake komanso kulimba kwake, zomwe zimapangitsa kuti ikhale yoyenera kugwiritsa ntchito zomwe zimafuna mphamvu komanso kulimba.Zikafika pakukana kwamankhwala, onse LDPE ndi HDPE amawonetsa kukana bwino kwa chinyezi ndi mankhwala, kuwapangitsa kukhala oyenera kuyika ndi kuyika zinthu.
Pankhani yakukhudzidwa kwa chilengedwe, LDPE ndi HDPE zonse ndi zida zobwezerezedwanso.Komabe, HDPE imavomerezedwa kuti ibwezeretsedwenso m'madera ambiri poyerekeza ndi LDPE.Izi ndichifukwa choti HDPE ili ndi mtengo wapamwamba pamsika wobwezeretsanso chifukwa champhamvu komanso kukhazikika kwake.Zotsatira zake, HDPE nthawi zambiri imakondedwa ndi olimbikitsa chilengedwe komanso ogula osamala.
Pomaliza, kusankha pakati pa HDPE ndi LDPE pamapeto pake kumatengera zomwe wogwiritsa ntchito amafuna.LDPE ndi yabwino kwa mapulogalamu omwe amafunikira kusinthasintha ndi kutambasula, pamene HDPE ndi yoyenera kugwiritsa ntchito zomwe zimafuna kukhwima ndi mphamvu.Zida zonsezi zili ndi zabwino ndi zoyipa zawo, ndipo ndikofunikira kuti mabizinesi ndi ogula akambirane ndi LDPE ndiOpanga mafilimu apulasitiki a HDPEkuti adziwe zinthu zabwino kwambiri pa zosowa zawo zenizeni.Pamapeto pake, zida zonse ziwirizi zimagwira ntchito yofunika kwambiri pakukwaniritsa zosowa zosiyanasiyana zamafakitale onyamula katundu, ulimi, ndi zomangamanga.
