HDPE raj yog ib hom PE raj, thiab qhov txawv ntawm nws thiab PE cov yas yeem yog:
1. Lub raj xa hluav taws xob HDPE yuav tsum raug rau tej qhov siab, thiab cov PE reagine nrog rau qhov siab nyhav thiab kev ua haujlwm zoo yuav tsum xaiv, xws li cov HDPE reag. Lub zog yog 9 lub sij hawm uas zoo tib yam ntawm polyethylene yeeb nkab (PE raj);
2. Hauv tag nrho cov yeeb yam hauv tshuab raj, HDPE muaj lub yas yas yas ntev. Lub siab dua qhov phaus nyhav, qhov hnyav dua-cov khoom qub, thiab ntau tshaj cov khoom siv hlau (xws li carbon steel, stainless hlau, bronze, thiab lwm yam.), Thiab PE yooj yim tsis muaj qhov no;
3. HDPE yeeb nkab yog cov khoom hloov tshiab ntawm cov yeeb nkab cov yeeb nkab thiab cov dej haus yeeb nkab hauv PVC. Ordinary PE raj tsis zoo.
4, HDPE yeeb nkab yog tsuas yog siv rau: municipal engineering dej khoom, kev tsim vaj tse nyob sab hauv tsev, sab nrauv faus dej thiab chaw thaj chaw, chaw ua haujlwm thaj av faus dej, kev kho raj qub thiab kho dej, botanical vaj, dej thiab lwm qhov chaw ntawm cov kav dej muaj zog thiab lwm yam. Qhov nruab nrab ceev hluav taws xob polyethylene yeeb nkab tsuas yog tsim rau cov roj gas, cov nkev, cov roj av fuels. Ib qho uas tsis tshua muaj kab mob polyethylene yog ib qhov dej.
High Density Polyethylene yeeb nkab, HDPE yeeb nkab】 【khoom "HDPE", "High Density Polyethylene" rau luv luv. HDPE yog ib hom tshuaj thermoplastic nrog high crystallinity thiab tsis-polarity. Cov tsos ntawm thawj HDPE yog xim dawb, nrog rau ib theem ntawm cov lus nyob rau hauv seem nyias.
PE yeeb nkab yog ib txoj yas yeeb nkab polyethylene, PE yog hom ntau yam yas, thiab muaj cov khoom zoo tshaj plaws rau lub neej thiab muaj tshuaj. PE yeeb nkab tau muab faib ua kom tsawg mus ceev polyethylene yeeb nkab, nruab nrab ntom polyethylene yeeb nkab thiab high-density polyethylene yeeb nkab.
