HDPE QHM32F HDPE-RF yeFloor kudziyisa pombi
QHM32F ipolyethylene resin ine hexene-1 se co-monomer inogadzirwa neUnipol process yeUCC, USA.Iyo ine mabhenefiti ezvakanaka kuchinjika, yakanakisa kugadzirisa mashandiro, kugadzikana kwekupisa uye kumanikidza kuramba.Inonyanya kushandiswa kugadzirwa kwepasi kupisa pombi, aluminium - plastiki composite pombi, solar chubhu.
PE-RT pombi rudzi rutsva rweisina - crosslinked polyethylene zvinhu zvinogona kushandiswa mupombi yemvura inopisa.Iyo copolymer ye ethylene uye octene inogadzirwa neakakosha mamorekuru dhizaini uye synthesis process, ine nhamba inodzoreka yemapazi ketani uye kugovera chimiro chemhando dze polyethylene.Iyo yakasarudzika mamorekuru chimiro inoita kuti zvinhu zvive zvakanakisa kushushikana kwekupwanya kuramba uye kwenguva refu hydrostatic simba.PE-RT pombi ine yakanaka kuchinjika, uye kubhenda kwayo modulus i550 MPa, uye kushushikana kwemukati kunogadzirwa nekukotama kwakadzikira.Nenzira iyi, zvinodzivirirwa kuti pombi inogona kukuvadzwa panzvimbo yekukotama nekuda kwekunetsekana.Kana ichivakwa (kunyanya munguva yechando), haidi maturusi akakosha kana kupisa kunokotama.Thermal conductivity ye 0. 4 W / (m·k), inofananidzwa ne PE-X chubhu, yakakwirira kudarika PP-R 0. 22 W/ (m·k) uye PB 0. 17 W/ (m·k), yakanakisa thermal conductivity, inokodzera uriri kupisa pombi
Application
QHM32F iresin yakakosha yePE-RT pombi inogadzirwa neQilu Branch yeSinopec vachishandisa tekinoroji yeUnipol.Chigadzirwa chacho chine kuchinjika kwakanaka, kuita kwakanakisa kwekugadzirisa, kugadzikana kwemafuta uye kusimba kuramba, izvo zvinogona kusangana nezvinodiwa zvekugadzirisa-kumhanya-mhanya pombi yemhando dzakasiyana dzekugadzira michina uye caliber, uye inogona kushandiswa kugadzira pasi kupisa pombi, aruminiyamu epurasitiki composite. pombi, pombi yemafuta, nezvimwe.
