Pankhani mafilimu pulasitiki, LDPE (otsika osalimba polyethylene) ndiHDPE (pamwamba kachulukidwe polyethylene)ndi zinthu ziwiri zomwe zimagwiritsidwa ntchito kwambiri.Zonsezi zimagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana, kuphatikizapo kulongedza katundu, ulimi, zomangamanga, ndi zina.Kumvetsetsa kusiyana pakatiMafilimu a LDPEndi mafilimu a HDPE ndi ofunikira posankha zinthu zoyenera kuti agwiritse ntchito.
Mafilimu onse a LDPE ndi HDPE amapangidwa ndi makampani ambiri padziko lonse lapansi.Opanga mafilimu a HDPEndiOpanga mafilimu a LDPEkupanga zinthuzi m'njira zosiyanasiyana, kuphatikiza mipukutu, mapepala, ndi zikwama, kuti zikwaniritse zosowa zosiyanasiyana za ogula.
Chimodzi mwazosiyana kwambiri pakati pa LDPE ndiMafilimu a HDPEndi mawonekedwe awo a maselo ndi kachulukidwe.HDPE imadziwika chifukwa cha kuchuluka kwake, zomwe zimapangitsa kuti zikhale zovuta komanso zolimba kuposa LDPE.LDPE, kumbali ina, imakhala ndi kachulukidwe kakang'ono, zomwe zimapangitsa kuti zinthuzo zikhale zosavuta.
Pankhani yakugwiritsa ntchito, makanema a HDPE amagwiritsidwa ntchito kwambiri pakuyika zinthu zolemetsa monga ma liner a mafakitale, ma tarps, ndi zotchingira zomangira.Kulimba kwake kolimba kwambiri komanso kukana kuphulika kumapangitsa kuti ikhale yoyenera kumadera ovuta.Kuonjezera apo,Mafilimu a HDPENthawi zambiri amagwiritsidwa ntchito mu geomembrane application pakusunga ndi kuteteza chilengedwe.
M'malo mwake, makanema a LDPE amayamikiridwa chifukwa cha kusinthasintha kwawo komanso kumveka bwino, kuwapangitsa kukhala abwino kugwiritsa ntchito monga kuyika chakudya, kukulunga ndi zikwama zacholinga chonse.Kukhoza kwake kugwirizana ndi mawonekedwe a zomwe zili mkati mwake ndikupereka kukana kwabwino kwa chinyezi kumapangitsa kukhala chisankho chodziwika pazinthu zosiyanasiyana zamapaketi.
Kusiyana kwina kwakukulu pakati pa LDPE ndiMafilimu a HDPEndiko kukana kwawo kutentha.HDPE ili ndi malo osungunuka kwambiri kuposa LDPE, kuwalola kuti azitha kupirira kutentha kwambiri.Katunduyu amapanga makanema a HDPE kukhala oyenera kugwiritsa ntchito zomwe zimafunikira kusindikizidwa kutentha kapena kutenthedwa ndi kutentha kwambiri.
Kuonjezera apo,Mafilimu a LDPE ndi HDPEali ndi zovuta zosiyanasiyana zachilengedwe chifukwa cha kachulukidwe komanso kubwezanso.Ngakhale zida zonse ziwiri zimatha kubwezeretsedwanso, HDPE nthawi zambiri imadziwika kuti ndi yokonda zachilengedwe chifukwa chakuchulukira kwake, zomwe zimapangitsa kuti anthu asagwiritse ntchito zinthu zambiri komanso kuti asatayike.AmbiriOpanga mafilimu a HDPEakuika patsogolo kukhazikika popereka njira zobwezerezedwanso komanso zokomera zachilengedwe kuti zikwaniritse kufunikira komwe kukukulirakulira kwa njira zopangira ma CD zosunga zachilengedwe.
Mwachidule, pamene onse LDPE ndiMafilimu a HDPEndi zida zosunthika zomwe zimagwiritsidwa ntchito mosiyanasiyana, kumvetsetsa kusiyana kwawo ndikofunikira pakusankha zinthu zoyenera pazosowa zanu zenizeni.Kaya ndi kulimba ndi kulimba kwa HDPE kapena kusinthasintha ndi kuwonekera kwa LDPE, chilichonse chili ndi zinthu zapadera zomwe zimatha kukwaniritsa zofunikira zosiyanasiyana.Pogwirizana ndi munthu wodziwika bwinoChithunzi cha LDPEndi opanga mafilimu a HDPE, makampani amatha kupeza zida zapamwamba zoyenera kuzigwiritsa ntchito, potsirizira pake zimathandizira kukulitsa magwiridwe antchito ndikuchita bwino.
