Lub fiberglass geogrid yog ua los ntawm fiberglass filaments woven thiab coated

1. Txheej txheem cej luam ntawm iav fiber geogrid

Cov iav fiber geogrid yog cov khoom siv geosynthetic zoo heev uas siv rau kev txhawb nqa txoj kev, kev txhawb nqa txoj kev qub, kev txhim kho hauv av thiab lub hauv paus av mos. Nws yog cov khoom semi-rigid ua los ntawm cov iav fiber muaj zog siab los ntawm kev siv tshuab warp knitting thoob ntiaj teb los ua cov khoom siv hauv paus mesh, thiab tom qab ntawd kho cov txheej txheem saum npoo. Nws yog ua los ntawm cov iav fiber filaments los ntawm kev knitting thiab txheej.

2. Cov yam ntxwv ntawm cov iav fiber geogrid

(1) Cov khoom siv kho tshuab

• Lub zog tensile siab, elongation qis: Nrog iav fiber ua cov khoom siv raw, nws muaj kev tiv thaiv deformation siab, thiab elongation thaum tawg yog tsawg dua 3%, uas ua rau nws tsis yooj yim rau elongate thiab deformed thaum dais sab nraud zog.
• Tsis muaj kev nkag mus ntev: Ua cov khoom siv txhawb nqa, nws tuaj yeem tiv taus kev hloov pauv hauv qab lub sijhawm ntev, thiab cov iav fiber yuav tsis nkag mus, uas tuaj yeem ua kom muaj kev ua haujlwm ntev ntawm cov khoom.
• Cov modulus ntawm elasticity siab: Nws muaj cov modulus ntawm elasticity siab thiab tuaj yeem tiv taus deformation thaum muaj kev ntxhov siab, xws li kev dais qee qhov kev ntxhov siab hauv cov qauv kev taug kev thiab tswj kev ruaj khov ntawm cov qauv.

(2) Kev hloov pauv kub

Kev ruaj khov thermal zoo: qhov kub yaj ntawm cov iav fiber yog 1000 ℃ Qhov saum toj no ua kom ntseeg tau tias qhov ruaj khov ntawm cov iav fiber geogrid kom tiv taus cua sov hauv qhov chaw kub siab xws li kev ua haujlwm paving, thiab kuj tseem siv tau rau hauv thaj chaw txias heev, qhia tau tias muaj kev tiv taus kub siab thiab qis.

(3) Kev sib raug zoo nrog lwm cov ntaub ntawv

• Kev Sib Xws nrog kev sib xyaw asphalt: Cov khoom siv siv rau hauv cov txheej txheem tom qab kho yog tsim los rau cov khoom sib xyaw asphalt, txhua lub fiber yog coated tag nrho thiab muaj kev sib xws siab nrog asphalt, tsis tsim kev sib cais los ntawm cov khoom sib xyaw asphalt hauv txheej asphalt, tab sis tau sib txuas ua ke.
• Kev sib txuas thiab kev txwv ntawm cov pob zeb sib xyaw: Nws cov qauv mesh tso cai rau cov pob zeb sib xyaw hauv cov pob zeb asphalt kom nkag mus rau hauv nws, tsim kom muaj kev sib txuas tshuab. Hom kev sib txuas no txwv kev txav mus los ntawm cov pob zeb sib xyaw, tso cai rau cov khoom sib xyaw asphalt kom ua tiav qhov xwm txheej compaction zoo dua thaum thauj khoom, txhim kho lub peev xwm thauj khoom, kev ua haujlwm hloov pauv khoom, thiab txo qhov deformation.

(4) Kev Ruaj Khov

• Kev ruaj khov ntawm lub cev thiab tshuaj lom neeg: Tom qab txheej nrog tus neeg sawv cev tshwj xeeb tom qab kho, nws tuaj yeem tiv taus txhua yam kev hnav lub cev thiab kev puas tsuaj ntawm tshuaj lom neeg, nrog rau kev puas tsuaj ntawm cov kab mob thiab kev hloov pauv huab cua, kom ntseeg tau tias nws cov kev ua tau zoo tsis cuam tshuam.
• Kev tiv thaiv alkali zoo heev thiab kev laus tiv taus: Tom qab kev kho saum npoo, nws muaj lub zog zoo hauv ntau qhov chaw sib txawv thiab tuaj yeem ua lub luag haujlwm ntev.
