Siv lub siab molecular polymer thiab nano-scale carbon dub ua cov ntaub ntawv tseem ceeb, nws yog tsim los ntawm extrusion thiab traction txheej txheem los tsim ib tug geogrid khoom nrog uniform mesh nyob rau hauv ib qho kev taw qhia.
Yas geogrid yog ib lub square lossis duab plaub polymer mesh tsim los ntawm kev ncab, uas tuaj yeem ua uniaxial stretching thiab biaxial stretching raws li cov lus qhia sib txawv thaum lub sij hawm tsim khoom.Nws punches qhov ntawm cov ntawv extruded polymer (feem ntau polypropylene los yog high-density polyethylene), thiab tom qab ntawd ua cov kev taw qhia ncab hauv cov cua sov.Lub uniaxially stretched daim phiaj yog tsim los ntawm ncab tsuas yog raws li qhov ntev ntawm daim ntawv, thaum lub biaxially stretched daim phiaj yog ua los ntawm txuas ntxiv mus rau stretch uniaxially stretched daim phiaj nyob rau hauv cov kev taw qhia perpendicular mus rau nws ntev.
Vim hais tias cov polymer ntawm cov yas geogrid yuav raug kho dua tshiab thiab taw qhia thaum lub sij hawm cua sov thiab kev txuas ntxiv thaum lub sij hawm tsim cov yas geogrid, lub zog sib txuas ntawm cov saw hlau molecular muaj zog, thiab lub hom phiaj ntawm kev txhim kho nws lub zog yog tiav.Nws elongation tsuas yog 10% mus rau 15% ntawm daim ntawv qub.Yog tias cov ntaub ntawv tiv thaiv kev laus xws li cov pa roj carbon dub tau ntxiv rau geogrid, nws tuaj yeem ua rau nws muaj zog zoo xws li acid tsis kam, alkali tsis kam, corrosion kuj thiab aging kuj.
