Cov khoom ua si zoo nkauj, cov khoom fibrous (PP lossis PE) ntawm cov khoom siv dag siv; hom khoom muab tub lim (silica sand, rubber pellet los yog sib xyaw ntawm ob qho tib si) thiab sau qhov tob; kua tsim.
1. Xaiv ntawm cov casses dag Cov nyom ua tau ntawm ob hom: mosaic thiab weaving. Knitted lawn nrog nylon weaving, tiav rau hauv ib daim pam. Muab piv rau mosaic tufted cov nyom, nws yog ib qho tseem ceeb, qhov nyom kim heev, qhov nyom ntawm sab nrauv hardness, cushioning kev ua haujlwm tsis zoo, tab sis cov nyom tsis zoo, muaj zog ua pov thawj 2. Khoom ua phaj khoom dag dag thiab xaiv cov dag Muaj ntau hom khoom siv: poly (Polypropylene, PP) thiab polyethylene (Polyethylene, PE). PP khoom ntawm cov khoom siv dag cua dub, qhov tsis muaj zog, feem ntau siv rau kev ua si xws li kev ntaus pob tesniv thiab lwm yam. Cov ntaub ntawv PE ntawm cov khoom siv dag ntxhib ntxaum, kev ua kom zoo, kev ua si ntawm cov neeg ua si puas, haum rau ntau yam kev ua si xws li football, football thiab lwm yam.
3. Kev Sau Cov Khoom Ua Si 1. Xaiv cov khoom ua kom tiav Cov khoom ntawm cov khoom siv dag yog feem ntau cov xuab zeb lossis cov roj hmab, thiab qee zaum tov nrog ob, thaum siv sib xyaw, qhov feem pua ntawm ob leeg nyob ntawm seb cov xwm txheej twg, Qhov kev faib ua feem ntawm 70% roj hmab cov khoom + 30% xuab zeb.
4. Cov tsim kua faj siv ua kua Tej yam qoob loo ua kom muaj qoob loo muaj cov kua nplaum, cov cw nrawm nrawm nrog permeability, puag txheej hauv cov qauv tsim cov yeeb nkab, kev tsim kho ntawm cov qauv cwj pwm li no, ntau dua. Tab sis qee lub tshuab tsis tsim cov kua ua kua, nws yog ib qho tsim nyog yuav tsum vam khom lub qhov dej ntawm qhov ntuj tso, ces qhov tsim nyog yuav tsum ua rau saum npoo av.
