Khoom nta:
Lub zog siab: siv lub zog muaj zog polypropylene, polyester, nylon thiab lwm yam khoom siv hluavtaws ua cov ntaub ntawv raw, nrog lub zog qub.Tom qab woven rau hauv cov qauv interweave tsis tu ncua, cov kabmob muaj peev xwm ntxiv tau txhim kho.
Durability: hluavtaws fiber ntau yog tus yam ntxwv los ntawm nws cov tsis kam mus rau denaturation, decomposition thiab huab cua.Muaj peev xwm tswj tau nws cov yam ntxwv qub rau lub sijhawm ntev.
Corrosion kuj: hluavtaws chemical fiber feem ntau muaj kua qaub, alkali tsis kam, npauj tiv thaiv, pwm kuj.
Dej permeability: Woven fabrics tuaj yeem tswj tau lawv cov qauv pores kom ua tiav cov dej permeability.
Kev khaws cia thiab kev thauj mus los yooj yim: vim nws lub teeb yuag, nws tuaj yeem ntim tau raws li qee qhov kev xav tau, yog li nws yooj yim heev rau kev thauj mus los, khaws cia thiab kev tsim kho.
Qhov zoo tsis cuam tshuam los ntawm qhov sib txawv ntawm qhov kub ntawm ~-30 ℃;
Daim ntawv thov:
Siv dav hauv kev txuag dej, hluav taws xob, mines, txoj kev thiab kev tsheb ciav hlau thiab lwm yam geotechnical engineering,
Feem ntau ua lub luag haujlwm hauv qab no:
Railway, txoj kev loj, tshav dav hlau khiav subgrade cov khoom siv ntxiv,
marsh txoj kev tsim kho cov khoom siv,
Frost, Frost insulation khoom,
asphalt txoj kev nto tawg tiv thaiv cov khoom,
av txheej cais lim khoom,
reservoir, mine beneficiation kua khoom,
high-rise tsev foundation tso kua dej,
dej pas dej ua ke, txoj kab nqes tiv thaiv cov khoom tiv thaiv yaig.
