Musiyano Pakati peLLDPE neLDPE
Musiyano pakati pemutsara wakaderera density polyethylene (LLDPE) uye yakaderera density polyethylene (LDPE)
1. Tsanangudzo
Linear low density polyethylene (LLDPE) uye yakaderera density polyethylene (LDPE) ese ari maviri epurasitiki zvinhu zvakatorwa kubva ethylene seyekutanga mbishi zvinhu. Zvisinei, dzinosiyana maererano nechimiro; LLDPE inogadzirwa uchishandisa imwechete catalyst tekinoroji, zvichikonzera mutsara chimiro uye yakakwira density, nepo LDPE iine isina kujairika cheni chimiro chine yakaderera density.
2. Zvinhu zvemuviri
LLDPE inoratidza mutsauko wakasiyana maererano nedensity uye nzvimbo yekunyungudika kana ichienzaniswa neLDPE. Yakajairika density range yeLLDPE iri pakati pe0.916-0.940g/cm3, ine melting point range ye122-128℃. Pamusoro pezvo, LLDPE inoratidza simba repamusoro uye maitiro ekupisa kupisa.
Kune rimwe divi, LDPE kazhinji ine density kubva pa0.910 kusvika 0.940g/cm3 uye nzvimbo yekunyungudika ye105-115 ℃ uku ichipa kuchinjika kwakanyanya uye kuoma.
3. Maitiro ekugadzirisa
Munguva yekugadzira, LDPE inogona kugadziriswa kuburikidza nekuvhuvhuta kuumba kana extrusion matekiniki ekugadzira akasiyana midziyo uye yekurongedza zvinhu zvakaita semafirimu nemabhegi. Kusiyana neizvi, nekuda kwekutakura mutoro wepamusoro uye simba remuchina, LLDPE inonyanya kukodzera kuburitsa machubhu nemafirimu.
4.Application minda
Nekuda kwekusiyana kwavo zvivakwa uye nzira dzekugadzirisa, LLDPE neLDPE vanowana maapplication munzvimbo dzakasiyana. LLDPE yakanyatsokodzera kugadzira mafirimu/machubhu emhando yepamusoro anoshandiswa mukugadzira zvinhu zvekurongedza senge zvekufukidzira zvekurima, mafirimu asingapinde mvura pamwe newaya/tambo. Sezvineiwo, LDPE inowana kukwana kukuru mukugadzira zvigadzirwa zvakapfava zvinosanganisira matoyi ematoyi emvura mapombi midziyo pamwe nekurongedza zvinhu.
Pakazere, Kunyangwe zvese LLDP neLPDE zviri muchikamu chepolyethylene mapurasitiki, anoratidza misiyano yakakosha kwete chete nezve zvivakwa zvemuviri, nzira dzekugadzirisa asiwo minda yekushandisa.
