Polypropylene (OPP) sealing daim kab xev yog cov khoom siv los tiv thaiv- corrosion. Nws cov khoom siv hauv paus yog woven polypropylene fiber ntau daim ntaub, nrog butyl roj hmab - hloov asphalt raws li cov anti-corrosion nplaum txheej. Cov qauv fibrous ntawm cov khoom siv hauv paus zoo tiv thaiv kev puas tsuaj los ntawm cov av nyuaj. Kev ntsuam xyuas kev laus tau ua pov thawj tias nws lub neej ntev corrosion kuj; Raws li kev soj ntsuam ntawm cov khoom zoo sib xws nyob txawv teb chaws, nws lub sijhawm tiv thaiv zoo tshaj 30 xyoo.
Cov txheej txheem tseem ceeb ntawm OPP los tiv thaiv - daim kab xev corrosion yog siv cov thev naus laus zis thev naus laus zis los txuas cov khoom siv hauv paus thiab cov nplaum nplaum, ua raws li cov ntaub ntawv tso tawm.
Qee cov tuam txhab lag luam hauv tsev tau ua tiav cov txheej txheem txawv teb chaws hauv xyoo 2002, xa mus rau -tam sim no kev tiv thaiv hauv tsev -corrosion daim kab xev technical standard SY/T 0414-1998.
Cov cuab yeej tsim khoom tseem ceeb suav nrog lub hauv paus cov khoom siv calendering unit, gluing unit, kaw -cov roj hmab sib xyaw chav tsev, ib chav tsev yas extrusion, thiab ib chav slitting.
