PE cov yeeb nkab dej yog cov khoom siv feem ntau siv rau cov kav dej, uas muaj kev tiv thaiv zoo corrosion, kub tsis kam, cuam tshuam tsis kam, thiab hnav tsis kam, thiab tuaj yeem ua tau raws li cov kev cai ntawm cov kav dej feem ntau. Tsis tas li ntawd, tus nqi ntawm cov kav dej PE kuj tseem pheej yig, ua rau nws yog qhov kev xaiv zoo tshaj plaws rau cov kav dej. Qhov zoo ntawm cov kav dej PE kuj tseem cuam tshuam txog kev nyab xeeb thiab kev nyab xeeb ntawm cov khoom siv dej, yog li ntawd, yuav ua li cas txiav txim siab qhov zoo ntawm cov kav dej PE yog qhov tseem ceeb tshwj xeeb.
1, Kev ntxub ntxaug zoo
Qhov zoo ntawm PE cov kav dej xa dej ncaj qha cuam tshuam rau lawv txoj kev thauj mus los, kev teeb tsa, thiab kev siv cov teebmeem. Yog li ntawd, cov neeg siv khoom yuav tsum xub saib lawv qhov chaw. Cov kav dej zoo PE yuav tsum muaj qhov sib luag, zoo ib yam, tsis muaj npuas, tsis muaj kab nrib pleb, thiab tsis muaj cov cim ntawm hnav thiab deformation. Yog tias muaj cov cim kev sib tsoo, deformations, thiab lwm yam tshwm sim nyob rau saum npoo, nws qhia tau tias yuav muaj teeb meem.
2, Dimensional yuam kev
Qhov loj ntawm PE cov kav dej thiab cov kav dej yuav tsum yog qhov tseeb, thiab qhov yuam kev loj kuj yog ib qho kev txhawj xeeb uas cov neeg siv khoom yuav tsum tau saib xyuas thaum yuav cov kav dej PE. Txhawm rau xyuas seb qhov ntev ntawm cov kav dej PE thiab nws cov khoom siv tau raws li qhov yuav tsum tau ua, ua tib zoo saib xyuas cov phab ntsa tuab, kev sib txuas lub zog, thiab qhov tseeb ntawm cov yeeb nkab txoj kab uas hla thaum ua kom raug ntsuas los ntawm cov chaw tsim khoom.
3, Kev ntxub ntxaug zoo ntawm cov kav dej
Cov khoom siv, kev siv thev naus laus zis, thiab cov kav dej zoo PE kuj tseem ceeb rau kev txiav txim siab lawv qhov zoo. Yuav tsum tau nws cov yeeb nkab qauv kom ntom ntom ntom ntom ntom, muaj kev cuam tshuam thiab corrosion kuj, thiab siab toughness. Tsis tas li ntawd, raws li daim ntawv thov tiag tiag, cov kav dej uas muaj cov ntaub ntawv tshwj xeeb xws li cov kav dej kub thiab cov kav dej kub tsis zoo tuaj yeem raug xaiv.
4, Kev ntxub ntxaug hauv tsheb
Tus nqi ntws ntawm PE cov kav dej yog lwm qhov tseem ceeb hauv kev txiav txim siab lawv qhov kev ua tau zoo. Txhawm rau muag cov khoom los ntawm cov kev sim xws li kev sim dej, kev sim siab sab hauv, thiab kev sim tshuab. Nyob rau tib lub sijhawm, rau cov kav dej uas muaj kev siv sib txawv, kev txheeb xyuas cov dej ntws yuav tsum tau ua raws li qhov xav tau tiag tiag los xyuas kom meej qhov ruaj khov ntawm cov khoom zoo.
