Dab tsi ntawm cov yas yog HDPE
Jul 04, 2023| 1.Dab tsi yogHDPE?
High-density polyethylene (HDPE) yog crystalline heev, uas tsis yog-polar thermoplastic resin. Nws cov tsos yog milky dawb, thiab cov seem nyias yog translucent mus rau ib qho twg. HDPE muaj kev tiv thaiv corrosion zoo thiab tuaj yeem tiv taus ntau yam tshuaj hauv tsev thiab kev lag luam.
2.Dab tsi yog cov yam ntxwv ntawm HDPE?
HDPE muaj cov yam ntxwv ntawm siab crystallinity thiab tsis-polarity. Nws yog ib qho tsis muaj tshuaj lom, tsis muaj ntxhiab, tsis muaj ntxhiab tsw dawb nrog cov ntsiab lus yaj ntawm li 130 degree thiab qhov txheeb ze ntawm 0.941 ~ 0.960. Nyob rau tib lub sijhawm, nws kuj muaj qhov kub thiab txias ua haujlwm, zoo tshuaj lom neeg ruaj khov thiab muaj zog txhua yam. Tsis tas li ntawd, HDPE kuj muaj siab rigidity thiab toughness, muaj zog dielectric zog, thiab tsis kam mus rau ib puag ncig kev nyuaj siab tawg.
Hauv luv luv, HDPE yog cov khoom siv polymer nrog kev ua tau zoo thiab muaj ntau yam kev siv. Hauv lub neej thiab kev tsim khoom, nws tuaj yeem siv rau hauv kev tsim khoom ntawm ntau lub thawv, xws li lub raj mis, lub thoob, thiab lwm yam, thiab tseem tuaj yeem siv los tsim cov kav dej, xov hlau thiab cables, cov khoom siv hluav taws xob, qhov chaw pib, cov khoom ua si menyuam yaus, thiab lwm yam.
