Polypropylene (OPP) sealing daim kab xev, tseem hu ua polypropylene reinforced fiber ntau tiv thaiv -corrosion daim kab xev, yog ib puag ncig tus phooj ywg los tiv thaiv -corrosion cov ntaub ntawv nrog ib tug polypropylene mesh- ntxiv dag zog woven fiber geotextile ua lub hauv paus khoom thiab butyl roj hmab thiab polyisobutylene - hloov asphalt asphalt. Cov khoom no ua raws li SY/T0414-2017 tus qauv, tsis muaj-kev ua qias tuaj thiab tsis- cov yam ntxwv txaus ntshai. Nws yog qhov tsim nyog rau kev tiv thaiv kev tiv thaiv sab nraud ntawm cov kav dej steel thiab kev tiv thaiv lub tank, tshwj xeeb tshaj yog rau kev tiv thaiv kev tiv thaiv sab nraud ntawm cov kav dej saum taub hau. Nws kuj tseem siv tau los ua ib qho kev tiv thaiv kev txi rau cov kav dej faus thiab hla ntu, thiab yog ib hom khoom siv los tiv thaiv corrosion.
Nws cov qauv fiber ntau tuaj yeem tiv taus kev puas tsuaj los ntawm cov av nyuaj. Cov nplaum txheej tuab yog 0.75-1.25mm, thiab cov kev ntsuam xyuas kev laus tau ua pov thawj tias nws lub neej tsis muaj zog tshaj 50 xyoo. Thaum lub sij hawm tsim kho, kev tshem tawm xeb mus rau qib St3 / Sa2.5 thiab daim ntawv thov ntawm cov primer tshwj xeeb yog xav tau. Qhov ntsuas kub siv tau yog -5-50 degree, thiab ib txheej tuaj yeem qhwv los ua daim kab xev. Cov khoom muaj qhov kub tsis kam ntawm -34℃rau 85 degree. Raws li nws cov UV tsis kam, tensile lub zog, thiab kev puas tsuaj, nws tuaj yeem siv rau hauv cov kav dej roj thiab roj thiab cov dej hauv nroog thiab cov dej ntws, nrog rau 3PE los tiv thaiv corrosion system yeeb nkab txuas. Kev thauj mus los thiab khaws cia yuav tsum tsis txhob muaj qhov kub thiab txias ncaj qha. Lub neej txee yog 12 lub hlis.
