1.HDPE imhando yepamusoro yekristallinity, isiri-polar thermoplastic resin inogadzirwa ne ethylene copolymerization. Kutaridzika kweiyo HDPE yepakutanga ichena mukaka, uye inopenya kusvika kune imwe nhanho muchikamu chidiki. Iine kupikisa kwakanakisa kumakemikari mazhinji emumba uye emaindasitiri, uye inokwanisa kuramba kuparara uye kunyungudika kwemafuta akasimba (concentrated nitric acid), asidhi uye alkali munyu uye organic zvinonyungudutsa (carbon tetrachloride). Iyo polymer haitore unyoro uye ine yakanaka yekudzivirira mvura kumhepo, iyo inogona kushandiswa kunyorova uye kudzivirira kwesepage.

2.MDPE inoratidzirwa nekushungurudzika kwezvakatipoteredza kuputsa kusagadzikana uye kuchengetedza simba kwenguva refu. Huwandu hwehukama hweMDPE ndeye 0.926-0.953, iyo crystallinity i70% -80%, avhareji yemamolecular uremu i200,000, iyo tensile simba i8-24 mpa, kureba panguva yekuzorora i50% -60%, tembiricha yekunyunguduka iri 126-135 ℃, uye kunyunguduka kuyerera kuri 0.1-35 g / maminitsi gumi. Thermal deformation tembiricha (0.46 mpa) 49-74 ℃.

3. Yakaderera density polyethylene ndiyo yakareruka siyana mu polyethylene resin. Zvichienzaniswa nepamusoro-density polyethylene, crystallinity yayo (55% -65%) uye softening poindi (90-100 ℃) yakaderera. Iyo ine yakanaka kupfava, kuwedzera, kujeka, kutonhora kuramba uye processability. Kugadzikana kwayo kwemakemikari kwakanaka, kunogona kumira asidhi, alkali uye munyu aqueous solution; Yakanaka magetsi ekudzivirira uye gasi permeability; Kutora mvura yakaderera; Nyore kupisa. Iyo midziyo yakapfava, ine yakanaka extensibility, magetsi ekuisa, kugadzikana kwekemikari, mashandiro ekugadzirisa uye kushomeka kwekushisa (kupikisa -70 ℃).

4. Kuenzaniswa neLDPE, LLDPE ine zvakanakira simba rakakwirira, kusimba kwakanaka, kusimba kwakasimba, kupisa kwekushisa, kutonhora kunotonhora, etc.LLDPE inewo yakanaka yezvakatipoteredza kusagadzikana kuputsa kusagadzikana, kubvarura kuramba uye zvimwe zvinhu, uye inogona kuramba asidi, alkali, organic solvents uye zvichingodaro.

Cherechedza: PE plastiki particles inoshandiswa zvakanyanya uye inoda kugadzirwa maererano nezvinodiwa nevatengi mumamiriro akasiyana.
