Kusiyana pakati pa zinthu za HDPE ndi MPVE

一、 Mitundu yosiyanasiyana

1.Zithunzi za HDPE: High Density Polyethylene ("HDPE" mwachidule), wotchedwanso low pressure Polyethylene, ndi mtundu wa translucent ndi mkulu crystallinity ndi sanali polar pamwamba pa mlingo winawake.Ndi utomoni wopanda polar thermoplastic wokhala ndi crystallinity yayikulu.

2. MPVE: Chitoliro cha malata cha MPVE ndi chitoliro chatsopano cha zimbudzi chomwe chinapangidwa ndi Kangtai Plastic Technology Group ku China.Amapangidwa ndi polyvinyl chloride ndi polyethylene polymerization ndipo ali ndi ufulu wodziyimira pawokha waluso.

二,Ntchito zosiyanasiyana

1.HDPE: imakhala ndi kutentha kwabwino komanso kuzizira kozizira, kukhazikika kwamankhwala abwino, komanso kumakhala ndi kukhwima kwakukulu ndi kulimba, mphamvu zamakina zabwino.Ma dielectric katundu, kukana kupsinjika kwa chilengedwe ndikwabwino.Kulimba, kulimba kwamphamvu ndi zokwawa za polyethylene yotsika kwambiri ndizabwinoko kuposa za polyethylene yotsika kwambiri.Kukana kuvala bwino, kutsekemera kwa magetsi, kulimba komanso kuzizira.Osalimba ngati HDPE.

2. MPVE: poyerekeza ndi chitoliro chamalata cha HDPE chapawiri-khoma, ntchito yokwanira ndi yabwino kuposa zida zapaipi zamalata zomwe zilipo zapawiri, zomwe ndizofunikira kwambiri pakupanga chitoliro cha malata apawiri.Ndi kukwaniritsa 20-25% kupulumutsa chuma, 10-25% kuchepetsa mtengo.Oyenera mvula chimbudzi chitoliro ndi otsika kuthamanga kumidzi ulimi wothirira chitoliro.

三,Kutsindika kosiyana

1.HDPE: HDPE imatsutsana kwambiri ndi mankhwala ambiri apanyumba ndi mafakitale.

2. MPVE: Ndi kuthina kwamadzi bwino, mtundu wopepuka komanso kutsika mtengo wonse, imakhala ndi chizolowezi cholowa m'malo mwa HDPE yokhala ndi makoma awiri.
