Isisekelo se-polypropylene esifushane sama-nonwoven geotextiles
Incazelo Yomkhiqizo
Ukucaciswa komkhiqizo:
Isisindo segremu ngu-100g/㎡～500g/㎡;ububanzi bungamamitha angu-1～6, futhi ubude buhambisana nezidingo zamakhasimende.
Izici Zomkhiqizo:
Izakhiwo zomzimba nezemishini ziphakeme izikhathi ezi-2 kuya kwezi-3 kunemikhiqizo evamile futhi amandla adonsela phansi athile aphansi ngesisindo esifanayo;
I-asidi enhle kakhulu nokumelana ne-alkali, ukunamathela okuhle kwe-hot-melt, nokumelana nokugqoka okuqinile.
Izimo zohlelo lokusebenza
I-polypropylene epunchwe ngama-geotextiles angalukwanga enaliti asetshenziselwa ikakhulukazi ungqimba olushelelayo phakathi kwe-CRTSII slab slab ballastless track kanye nengaphezulu logodo likajantshi ozinikele wabagibeli, kanye nongqimba lokuhlukanisa phakathi kwe-CRTSII slab ballastless track kanye nepuleti lokungqubuzana, futhi kungaba esetshenziswa kabanzi emigwaqweni esheshayo, ezitimeleni, emachwebeni, ezikhumulweni zezindiza, ezindaweni zodaka ezisogwini, ekubuyiselweni kabusha, ekuvikelweni kwemvelo kanye neminye imikhakha yobunjiniyela.
Amapharamitha womkhiqizo
I-JTT 992.1-2015 “I-Geosynthetics kubunjiniyela bomgwaqo omkhulu - I-Geotextiles Ingxenye 1: Isisekelo esifushane se-polypropylene sama-geotextiles angalukiwe”
