Dab tsi yog high density polyethylene
Dec 31, 2023| High-density polyethylene (HDPE) yog cov hmoov dawb los yog granular khoom. Tsis muaj tshuaj lom, tsis muaj ntxhiab, nrog crystallinity ntawm 80% mus rau 90%, qhov muag muag ntawm 125 txog 135 degree, thiab kev pabcuam kub txog li 100 degree; nws hardness, tensile zog thiab creep zog yog zoo dua li cov uas tsis muaj-density polyethylene; nws hnav tsis kam thiab hluav taws xob khoom yog Nws muaj cov rwb thaiv tsev zoo, toughness thiab txias tsis kam; zoo tshuaj stability, insoluble nyob rau hauv tej organic hnyav ntawm chav tsev kub, thiab resistant rau corrosion los ntawm acids, alkali thiab ntau yam ntsev; zaj duab xis muaj tsawg permeability rau dej vapor thiab huab cua, thiab yog dej absorbent. Tsawg; kev laus tsis zoo, ib puag ncig kev nyuaj siab tawg kuj tsis zoo li tsawg-density polyethylene, tshwj xeeb tshaj yog thermal oxidation yuav txo nws cov kev ua tau zoo, yog li cov antioxidants thiab ultraviolet absorbers yuav tsum tau ntxiv rau cov resin los txhim kho qhov tsis txaus no. High-density polyethylene zaj duab xis muaj qhov tsis tshua muaj thermal deformation kub thaum muaj kev ntxhov siab, yog li yuav tsum tau saib xyuas thaum siv nws.
