Iipolypropylene ezimfutshane ezisisiseko ze-nonwoven geotextiles
Ingcaciso yeMveliso
Inkcazo yeMveliso:
Ubunzima begram yi-100g/㎡～500g/㎡;ububanzi yi-1～6 yeemitha, kwaye ubude buhambelana neemfuno zabathengi.
Iimpawu zeMveliso:
Iimpawu zomzimba kunye noomatshini zi-2 ukuya ku-3 ngamaxesha aphezulu kuneemveliso eziqhelekileyo kwaye ubunzima obuthile buphantsi kobunzima obufanayo;
I-asidi egqwesileyo kunye nokumelana ne-alkali, ukuncamathela okuhle kwe-hot-melt, kunye nokunganyangeki okuqinileyo.
Iimeko zeSicelo
I-polypropylene ehlatywe inaliti engalukwanga geotextiles isetyenziselwa ikakhulu umaleko wokutyibilika phakathi kweCRTSII slab slab ballastless track kunye nomphezulu womqadi kaloliwe ozinikeleyo wabakhweli, kunye nomaleko wokwahlula phakathi kweCRTSII slab ballastless track kunye nepleyiti yokukhuhlana, kwaye inokuba nayo. isetyenziswa ngokubanzi kwiindlela zokubonisa, oololiwe, amazibuko, izikhululo zeenqwelo-moya, iindawo zodaka ezigudle unxweme, ukugcinwa ngokutsha, ukhuseleko lokusingqongileyo kunye nezinye iinkalo zobunjineli.
IiParameters zeMveliso
I-JTT 992.1-2015 “I-Geosynthetics kubunjineli bendlela enguhola-i-Geotextiles iSahlulo soku-1: Isiseko esifutshane se-polypropylene se-nonwoven geotextiles”
