Dhuxul-gaaban ee polypropylene geotextiles nonwoven
Sharaxaada Alaabta
Tilmaamaha Alaabta:
Miisaanka garaamku waa 100g/㎡～500g/㎡;ballaciisu waa 1～6 mitir, dhererkuna waa hadba baahida macaamiisha.
Tilmaamaha Alaabta:
Qalabka jireed iyo farsamada ayaa 2 ilaa 3 jeer ka sarreeya alaabta caadiga ah iyo cufnaanta gaarka ah ayaa u hooseeya miisaanka isku midka ah;
Aashito heer sare ah iyo iska caabin alkali ah, ku dheggan-kuleyl wanaagsan, iyo iska caabin xoog leh.
Xaaladaha Codsiga
Irbada polypropylene-fudud ee geotextiles-ka aan tolka lahayn ayaa inta badan loo isticmaalaa lakabka silmaya ee u dhexeeya CRTSII slab ballastless track iyo dusha sare ee rakaabka ee tareenka u heellan, iyo lakabka go'doominta ee u dhexeeya jidka CRTSII ee ballastless-ka iyo saxanka khilaafsan, sidoo kale wuxuu noqon karaa si weyn looga isticmaalo waddooyinka, tareenada, dekedaha, garoomada diyaaradaha, dhoobada xeebaha, dib u soo celinta, ilaalinta deegaanka iyo goobaha kale ee injineernimada.
