Biaxially stretched yas geogrid yog tsim rau kev txhawb nqa lub hauv paus nrog thaj chaw loj bearing peev xwm

1. Kev txhais thiab kev tsim cov yas geogrid uas ntev ob sab

Cov yas geogrid uas rub ob sab (hu ua ob sab yas grid luv luv) yog cov khoom siv geomaterial ua los ntawm cov polymer molecular siab los ntawm kev extrusion, phaj tsim thiab xuas nrig ntaus, thiab tom qab ntawd ncab ntev thiab hla. Hauv cov txheej txheem ntau lawm, polypropylene yog siv ua cov khoom siv raw tseem ceeb (me me ntawm cov khoom siv polyethylene kuj siv), thiab cov khoom tiv thaiv kev laus thiab tiv thaiv ultraviolet ntxiv rau. Tom qab cov khoom siv raw raug cua sov thiab extruded, cov khoom siv raw ces ncab sib npaug nrog tib lub zog hauv cov lus qhia ntev thiab hla. Cov khoom siv no muaj lub zog tensile zoo hauv ob qho tib si ntev thiab hla, thiab cov qauv no tuaj yeem muab lub kaw lus interlocking zoo tagnrho rau kev tuav lub zog thiab kev sib kis hauv av, uas yog qhov tsim nyog rau kev txhawb nqa lub hauv paus nrog thaj chaw loj.

2. Cov yam ntxwv ntawm cov yas geogrid uas txuas ntxiv ob sab

• Cov khoom siv kho tshuab
  • Muaj zog heev：Ua los ntawm cov polyester lossis poly thiab lwm yam khoom siv muaj zog, nws muaj lub zog tensile siab thiab tawg tsis kam, thiab tuaj yeem tiv taus cov khoom hnyav. Nws muaj lub zog tensile zoo hauv ob qho tib si longitudinal thiab transverse kev taw qhia, uas tuaj yeem ua tau raws li qhov xav tau ntawm kev tsim kho thiab kev tsim kho cov kev cai thauj khoom. Piv txwv li TGSG30KN Lub teb chaws tus qauv geogrid yog ua los ntawm cov khoom siv polymer hluavtaws, uas muaj lub zog tensile zoo thiab lub zog compressive, thiab tuaj yeem dais cov khoom loj.
  • Zoo dua creep tsis kamNyob rau hauv qhov kev ua ntawm kev ntxhov siab (load), nws tuaj yeem daws tau zoo dua nrog qhov xwm txheej uas cov khoom siv (deformation) hloov pauv nrog lub sijhawm, thiab xyuas kom meej tias muaj kev ruaj khov thaum siv ntev.
• Qhov ruaj khov
  • Kev laus tiv taus zooTom qab kev kho tshwj xeeb, nws muaj kev tiv thaiv kev laus zoo, thiab tuaj yeem tiv taus kev cuam tshuam ntawm ib puag ncig sab nraud ntev yam tsis yooj yim puas tsuaj. Piv txwv li, lub geogrid biaxially stretched tuaj yeem siv sab nraum zoov ntev yam tsis muaj qhov pom tseeb ntawm kev laus tom qab kev kho tshwj xeeb, TGSG30KN Lub teb chaws tus qauv geogrid muaj cov txheej txheem kho tshwj xeeb thiab muaj kev tiv thaiv kev laus. Nws tuaj yeem siv sab nraum zoov ntev yam tsis muaj qhov pom tseeb ntawm kev laus.
  • Kev tiv thaiv huab cua zoo： Ua los ntawm cov khoom siv polymer molecular siab, nws tuaj yeem siv sab hauv tsev ntev yam tsis raug cuam tshuam los ntawm ib puag ncig, thiab tuaj yeem tswj kev ua haujlwm ruaj khov nyob rau hauv cov huab cua sib txawv.
  • Muaj zog tiv taus corrosion： Nws tuaj yeem tiv taus qhov kev puas tsuaj ntawm cov tshuaj lom neeg xws li tshuaj lom neeg, kua qaub thiab alkalis, yog li nws tuaj yeem siv rau hauv qhov chaw noo thiab corrosive rau lub sijhawm ntev. Piv txwv li, lub grille yas biaxially ncab tuaj yeem tiv taus qhov kev puas tsuaj ntawm qhov chaw hnyav xws li kua qaub thiab alkalis thiab av noo.
