Daim ntawv thov ntawm HDPE kav

HDPE yeeb nkab yog ib qho ntawm cov kav dej uas siv ntau tshaj plaws, uas tuaj yeem ua tau raws li qhov xav tau ntawm ntau yam xws li cov khoom siv dej, cov roj xa hluav taws xob, cov kav dej phwj tuaj thiab cov kav dej thiab cov ntawv thov kev lag luam. Nrog rau kev paub txog kev tiv thaiv ib puag ncig, kev ua tau zoo ntawm HDPE kav dej tau raug lees paub thiab nyiam los ntawm ntau tus neeg.

Kev Siv Dej

Kev siv cov kav dej HDPE hauv cov khoom siv dej hnub rov qab mus rau xyoo 1960s, thaum lawv tau pib siv los hloov cov kav hlau los yog cov cement. Qhov zoo ntawm cov kav dej HDPE tshaj cov kav dej ib txwm muaj yog lawv cov kev sib txhuam qis thiab kev ua haujlwm zoo rau cov tshuaj lom neeg thiab thermal expansion, uas tso cai rau lawv ua kom tau raws li qhov xav tau ntawm ntau yam khoom siv dej. Tsis tas li ntawd, HDPE yeeb nkab kuj muaj lub zog tensile zoo thiab cuam tshuam, thiab tuaj yeem tiv taus siab sab hauv thiab sab nraud, khoov thiab ncab zog. Qhov no muab kev lav zoo rau kev ua haujlwm ruaj khov ntawm cov khoom siv dej.

Gas qhov system

Hauv kev faib cov roj, cov kav dej HDPE feem ntau yog siv los thauj cov nkev, roj thiab lwm yam roj. Vim nws cov hluav taws kub thiab tshuaj lom neeg tsis kam, HDPE cov kav dej tuaj yeem tiv taus qhov cuam tshuam ntawm hluav taws thiab cov pa tawm mus rau qee qhov, yog li txo qhov kev pheej hmoo ntawm kev nyab xeeb. Tsis tas li ntawd, cov kav dej HDPE kuj tseem muaj kev tiv thaiv siab thiab muaj peev xwm tiv taus cov dej num xws li kev thauj mus los thiab kev xa tawm roj.

Cov dej phwj tuaj thiab cov kav dej

HDPE kav dej yog siv rau hauv cov dej khib nyiab thiab cov kav dej tsuas yog siv rau kev kho dej khib nyiab xws li cov dej khib nyiab hauv nroog thiab cov dej khib nyiab hauv nroog. Vim nws muaj peev xwm tiv taus corrosive tshuaj thiab zoo UV tsis kam, HDPE kav yuav siv tau ruaj khov nyob rau hauv hnyav underground drainage ib puag ncig, yog li xyuas kom meej lub du paug thiab kev kho mob ntawm cov dej khib nyiab hauv nroog. Tsis tas li ntawd, HDPE yeeb nkab muaj kev sib khi zoo hauv cov yeeb nkab txuas, txo qhov muaj peev xwm ntawm cov dej xau, thaum muaj peev xwm tiv taus qhov kub thiab txias, thiab lwm yam.

Cov ntawv thov kev lag luam

HDPE kav kuj muaj ntau hom kev lag luam, xws li xa cov dej khib nyiab thiab cov khoom siv tshuaj lom neeg uas muaj cov kua qaub thiab alkali, xa cov khoom siv granular xws li yas granules, thee plua plav, cement, thiab lwm yam. Cov tshuaj tiv thaiv thiab corrosion kuj ntawm HDPE kav tuaj yeem ua tau raws li qhov xav tau. kev xav tau ntawm kev xa cov kua lossis cov pa roj ntawm cov khoom sib txawv, txo cov pa phem ib puag ncig thiab kev nyab xeeb kev nyab xeeb, thaum tseem txhim kho kev tsim khoom thiab ua haujlwm zoo.

Nyob rau hauv ib lo lus, HDPE kav dej muaj ib tug dav daim ntawv thov kev cia siab nyob rau hauv ntau yam xws li dej system, gas tis system, dej phwj tuaj thiab cov kav dej thiab muaj kev siv, thiab lwm yam.
