Polypropylene (OPP) sealing daim kab xev yog cov khoom siv polymer nrog cov tshuaj lom neeg ruaj khov thiab cov khoom siv dag zog, tiv thaiv corrosion ntawm cov kav dej sab hauv thiab sab nraud.
OPP los tiv thaiv- daim kab xev corrosion feem ntau muaj peb ntu: lub hauv paus zaj duab xis, txheej nplaum, thiab zaj duab xis tso tawm.
Cov khoom siv hauv paus yog polypropylene mesh- siv zog woven fiber geotextile, feem ntau yog 0.3mm txog 0.6mm tuab. Cov nplaum txheej yog ua los ntawm cov roj hmab butyl thiab polyisobutylene- hloov roj av asphalt, nrog lub thickness ntawm 0.75mm txog 1.25mm.
Tag nrho cov thickness ntawm cov khoom yog li ntawm 1.00mm mus rau 1.80mm, thiab txawv specifications muaj nyob rau hauv ob peb ua ke raws li cov anti{2}}corrosion qib, xws li zoo tib yam, reinforced, thiab ntxiv - muaj zog.
