Fasten Hopesun Polyethylene (РЕ) kav yog tsim los ntawm high-density polyethylene cob, thiab cov txheej txheem ntau lawm yog nruj me ntsis raws li GB / T ntsig txog cov qauv.Cov khoom tsis muaj cov khoom hnyav hlau ntxiv, tsis ntsuas, tsis tsim cov kab mob, tsis ua rau cov pa phem thib ob rau qhov nruab nrab, thiab muaj tshuaj lom neeg zoo.
PE yeeb nkab muaj qhov kub thiab txias tsis kam, siab rigidity thiab toughness, zoo lub cev thiab txhua yam khoom, cuam tshuam tsis kam, muaj zog poob siab, yoog raws thiab kev sib tw, thiab yoog mus rau ntau yam kev hloov ntawm ib puag ncig.РЕ yeeb nkab welding txheej txheem yog yooj yim, thiab paub tab vuam tshuab ua kom muaj zog sib cuam tshuam, yog li kev tsim kho yooj yim thiab tag nrho cov nqi tsim nyog yog tsawg.
Lub puab phab ntsa ntawm cov yeeb nkab РЕ thiab cov yam ntxwv uas tsis yog-nplaum ntawm cov khoom nws tus kheej txiav txim siab lub peev xwm ntau dua ntawm cov khoom, yog li kev siv hluav taws xob sib kis tau qis dua.
