Daim ntawv dej ntws
Cov ntawv phaj dej yog ib hom phaj dej. Feem ntau nws yog lub duab plaub fab lossis lub duab plaub fab nrog qhov loj me me, xws li cov lus qhia dav dav ntawm 500mm × 500mm, 300mm × 300mm lossis 333mm × 333mm. Nws yog ua los ntawm cov khoom siv yas xws li polystyrene (HIPS), polyethylene (HDPE) thiab polyvinyl chloride (PVC). Los ntawm cov txheej txheem txhaj tshuaj molding, cov duab xws li conical protrusions, stiffening rib bumps lossis hollow cylindrical porous qauv raug tsim rau ntawm lub phaj yas hauv qab, thiab ib txheej ntawm lim geotextile raug nplaum rau saum npoo.

Iav fiber geogrid
Cov iav fiber geogrid yog ib hom geogrid tsim los ntawm kev siv alkali - dawb thiab tsis muaj fiber roving ua cov khoom siv tseem ceeb. Nws yog thawj zaug ua rau cov khoom siv net - qauv los ntawm cov txheej txheem tshwj xeeb weaving, thiab tom qab ntawd dhau los ntawm kev kho saum npoo. Cov iav fiber muaj lub zog siab, modulus siab, thiab elongation qis, muab lub hauv paus zoo rau cov khoom siv kho tshuab ntawm geogrid.
-
Hlau-yas geogrid
Cov hlau-yas geogrid siv cov hlau muaj zog (lossis lwm cov fibers) ua lub hauv paus ntawm kev ntxhov siab. Tom qab kev kho tshwj xeeb, nws tau sib xyaw nrog cov yas xws li polyethylene (PE) lossis polypropylene (PP) thiab lwm yam khoom ntxiv, thiab cov txheej txheem extrusion tau tsim cov kab sib xyaw ua ke muaj zog tensile. Qhov saum npoo ntawm cov kab feem ntau muaj cov qauv embossed ntxhib. Txhua daim kab ces raug woven lossis clamped longitudinally thiab transversely ntawm qee qhov chaw, thiab cov pob qij txha tau welded los ntawm kev sib txuas tshwj xeeb thiab fusion vuam thev naus laus zis kom thaum kawg tsim cov hlau-yas geogrid. -
Biaxially - Stretched Yas Geogrid
Nws yog ib yam khoom siv geosynthetic tshiab. Nws siv cov polymers molecular siab xws li polypropylene (PP) lossis polyethylene (PE) ua cov khoom siv raw. Cov phaj raug tsim los ntawm kev ua yas thiab extrusion, tom qab ntawd punched, thiab thaum kawg ncab longitudinally thiab transversely. Thaum lub sijhawm tsim khoom, cov saw hlau siab molecular ntawm cov polymer raug rov teeb tsa thiab taw qhia thaum cov khoom raug cua sov thiab ncab. Qhov no ua kom muaj zog ntawm kev sib txuas ntawm cov saw hlau molecular thiab yog li ua rau nws lub zog nce ntxiv. Tus nqi elongation tsuas yog 10% - 15% ntawm cov phaj qub.

Yas Geogrid
- Nws feem ntau yog ua los ntawm cov khoom siv polymer siab xws li polypropylene (PP) lossis polyethylene (PE). Pom tseeb, nws muaj cov qauv zoo li daim phiaj. Cov qauv daim phiaj no yog tsim los ntawm cov txheej txheem tsim khoom tshwj xeeb. Feem ntau, cov khoom siv polymer raw yog ua ntej rau hauv lub phaj, thiab tom qab ntawd los ntawm cov txheej txheem xws li xuas nrig thiab ncab, geogrid nrog daim phiaj ib txwm raug tsim. Cov duab ntawm daim phiaj tuaj yeem yog square, rectangular, diamond-puab, thiab lwm yam. Qhov loj ntawm daim phiaj thiab qhov tuab ntawm geogrid sib txawv raws li cov kev cai tshwj xeeb thiab cov qauv tsim khoom.
