Dab tsi yog qhov txawv ntawm HDPE yeeb nkab thiab PE yeeb nkab?
HDPE yeeb nkab yog ib hom PE yeeb nkab. Qhov sib txawv ntawm nws thiab cov yeeb nkab PE zoo tib yam yog HDPE yeeb nkab yuav tsum tiv taus qee qhov siab. Feem ntau, PE resin nrog qhov hnyav molecular thiab cov khoom siv zoo, xws li HDPE resin, raug xaiv. Lub zog yog 9 npaug ntawm cov yeeb nkab polyethylene zoo tib yam (PE yeeb nkab); Ntawm tag nrho cov engineering plastics, HDPE muaj qhov hnav tsis kam ntawm cov yas siab tshaj plaws. Qhov siab dua qhov hnyav molecular, qhov hnav ntau dua - tiv taus cov khoom, txawm tias ntau dua li cov ntaub ntawv hlau (xws li carbon steel, stainless hlau, tooj liab, thiab lwm yam), PE zoo tib yam tsis muaj qhov no.
Cov kav dej HDPE yog cov khoom hloov ntawm cov kav hlau ib txwm siv thiab cov kav dej PVC, thiab cov kav dej PE zoo tib yam tsis tuaj yeem. Cov kav dej HDPE feem ntau yog siv rau: cov kav dej hauv nroog engineering, cov khoom siv dej hauv tsev hauv tsev, sab nraum zoov faus dej thiab cov tsev nyob, faus dej hauv cov chaw tsim khoom, kho cov kav dej qub, kev kho dej hauv cov kav dej, kev ua teb, kev siv dej. thiab lwm thaj chaw ntawm kev lag luam cov kav dej, thiab lwm yam. Qhov nruab nrab ntom ntom polyethylene yeeb nkab tsuas yog tsim rau kev xa cov pa roj carbon monoxide, cov roj ntsha thiab cov roj liquefied roj av. Tsawg ntom polyethylene kav yog hoses.
