Kana zvasvika kumafirimu epurasitiki, LDPE (yakaderera density polyethylene) uyeHDPE (yakakwirira density polyethylene)ndiwo maviri anonyanya kushandiswa zvinhu.Ose ari maviri anoshandiswa zvakanyanya mumaindasitiri akasiyana, anosanganisira kurongedza, kurima, kuvaka, nezvimwe.Kunzwisisa kusiyana pakatiLDPE mafirimuuye HDPE mafirimu akakosha pakusarudza iyo chaiyo zvinhu kune chaiyo application.
Ose maviri LDPE uye HDPE mafirimu anogadzirwa nemakambani mazhinji pasirese.HDPE vagadziri vemafirimuuyeLDPE vagadziri vemafirimugadzira zvinhu izvi nenzira dzakasiyana siyana, kusanganisira rolls, machira, uye mabhegi, kuti zvizadzise zvinodikanwa zvakasiyana zvevatengi.
Imwe yemisiyano mikuru pakati peLDPE neHDPE mafirimundiko kuumbwa kwavo kwemamorekuru uye kuwanda.HDPE inozivikanwa nekuwanda kwayo, izvo zvinoita kuti iome uye igare yakasimba kupfuura LDPE.LDPE, kune rumwe rutivi, ine yakaderera density, zvichiita kuti zvinhu zviwedzere kushanduka.
Panyaya yemashandisirwo, mafirimu eHDPE anowanzo shandiswa mukuremedza-basa kurongedza senge maindasitiri liner, tarps, uye zvekuvharisa zvekuvaka.Simba rayo repamusoro-soro uye kupikisa kwepuncture kunoita kuti ive yakakodzera nzvimbo dzakaoma.Uyezve,HDPE mafirimuanowanzo shandiswa mu geomembrane zvikumbiro zvekuchengetedza zvakatipoteredza uye kuchengetedza.
Panzvimbo iyoyo, mafirimu eLDPE anofarirwa nekuchinjika uye kujeka, achiaita akanakira maapplication akadai sekurongedza chikafu, shrink kuputira uye mabhegi echinangwa.Kugona kwayo kuenderana nechimiro chezviri mukati uye kupa yakanakisa unyoro kuramba kunoita kuti ive yakakurumbira sarudzo kune dzakasiyana siyana dzekurongedza.
Mumwe musiyano mukuru pakati peLDPE neHDPE mafirimundiko kuramba kwavo kupisa.HDPE ine nzvimbo yakakwira yekunyungudika kupfuura LDPE, ichiibvumira kushingirira tembiricha yakakwira.Ichi chivakwa chinoita HDPE mafirimu akakodzera maapplication anoda kupisa chisimbiso kana kuratidzwa kune tembiricha yepamusoro.
Uyezve,LDPE uye HDPE mafirimuvane zvakasiyana siyana zvinokanganisa kwezvakatipoteredza nekuda kwekuwanda kwavo uye kushandiswazve.Nepo zvese zviri zviviri zvigadziriswa, HDPE inowanzoonekwa seine hushamwari zvakatipoteredza nekuda kwehuwandu hwayo hwepamusoro, izvo zvinokonzeresa kushandiswa kushoma kwezvinhu uye kushomeka kwemarara.VazhinjiHDPE vagadziri vemafirimuvari kukoshesa kusimba nekupa zvinodzokororwa uye eco-hushamwari sarudzo kusangana nekukura kuri kudiwa kwezvakatipoteredza zvine hushamwari ekurongedza mhinduro.
Muchidimbu, nepo zvese zviri zviviri LDPE uyeHDPE mafirimuzvinhu zvakasiyana-siyana zvine huwandu hwakasiyana hwekushandisa, kunzwisisa mutsauko wazvo kwakakosha pakusarudza zvinhu zvakafanira kune zvaunoda chaizvo.Kunyangwe kuri kuoma uye kusimba kweHDPE kana kuchinjika uye kubuda pachena kweLDPE, chinhu chimwe nechimwe chine zvimiro zvakasiyana zvinogona kusangana nezvinodiwa zvakasiyana.Nokubatana nemunhu ane mbiriLDPE firimuuye HDPE mugadziri wemufirimu, makambani anogona kuwana zvemhando yepamusoro zvinhu zvakakodzera kune avo chaiwo mashandisirwo, pakupedzisira zvichibatsira kuwedzera kushanda zvakanaka uye kubudirira.
