Cov tshuaj tiv thaiv zoo: HDPE kav dej tiv taus corrosion los ntawm ntau yam tshuaj lom neeg, thiab cov tshuaj hauv cov av yuav tsis ua rau muaj kev puas tsuaj rau cov kav dej. Polyethylene yog ib qho hluav taws xob insulator, yog li nws yuav tsis rot, xeb lossis electrochemical corrosion; Tsis tas li ntawd, nws yuav tsis txhawb kev loj hlob ntawm algae, kab mob los yog fungi; Nws yog resistant rau kev laus thiab muaj lub neej ntev kev pab cuam: nws muaj 2-2.5% tusyees faib Carbon dub polyethylene kav yuav khaws cia los yog siv sab nraum zoov rau 50 xyoo, thiab yuav tsis puas los ntawm ultraviolet hluav taws xob; zoo hnav tsis kam: qhov hnav tsis kam ntawm cov kav dej HDPE thiab cov kav hlau hlau qhia tau hais tias qhov hnav tsis kam ntawm HDPE kav yog cov kav hlau 4 zaug. Hauv kev thauj mus los ntawm av nkos, HDPE kav dej muaj qhov hnav zoo dua li cov kav hlau, uas txhais tau hais tias HDPE kav muaj lub neej ntev kev pab cuam thiab kev lag luam zoo dua.
