Panelu fibre de verre bu baax

FRP anti-planche corrosion ay macceer composite yu xarañ lañu yuñ defaree ngir mu mëna xeex ay produit chimik yu baax te mënul ñàkk ci anam yu metti yu usine yi ak ci environmaa bi. Ñu ngi ko defaree matris resin bu am doole ak ay fibre de verre yuy dooleel, plaque yooyu dañu boole doole mekanik ak baña yàqu, loolu mooy tax ñu mëna wecci macceer yu yàgg yu melni wen, bant wala beton ci gox yu am corrosion.

Basic structure bu FRP anti-corrosion boards amna ñatti couche yu am solo: couche gel coat biy muur, couche fibre de verre biy dooleel, ak couche resine bi koy jàppale. Couche couche gel bi, ñu koy faral di defaree polyester bu amul saturation wala resine vinyl ester, mooy nekk bariyer bi gëna biti, muy joxe surface bu nooy, bu amul pore, buy tere dugg chimik yi ak yàqu-yàqu UV yi. Ci suufa suuf, dañu defar ay fibre de verre yuy dooleel ci xeetu tapi wala tissu buñ tissu, loolu dafay jox doole mekanik ci tablo bi, ba noppi fexe ba mu mëna dékku ay sargal ak ay impact. Resine biy jàppale tablo bi, dafay faral di yokk ay inhibitëru corrosion, loolu dafay gëna rafetal guddaayu tablo bi ak gëna dëgëral diggante ñaari diisaay yi. Defarkat yi mën nañu méngale yaatuwaayu couche bu nekk (diggante 2 mm ba 15 mm) méngoo ak bëgg-bëggu jëfandikoo gi, suko defee ñu mëna yemale diisaay bi ak kàttan gi.

Benn ci màndarga yi gëna fës ci plate fibre de verre yuy tere corrosion mooy seen dëgër bu rëy ci wàllu chimik. Dañuy muñ bu baax mbir yu bari yuy yàq, lu ci melni asid (lu melni asid sulfurik ak asid chlorik), base (hydroxyde de sodium, ndoxu amoniak), xorom, solvant, ak ndox yu baaxul yi bawoo ci usine yi. Plaque fibre de verre wuute na ak plaque metal yi mën nañu xoosu wala ñu yàqu suñu nekkee ci biir substance chimik yu mel noonu, ndax plaque fibre de verre mën nañu baña yàqu doonte dañu leen laal lu yàgg. Resistance chimik bi ñu ngi ko firnde ci test yu tar, lu ci melni test tolerans chimik buñu sukkandikoo ci ASTM D543 standard, fu ñuy dugal échantillon yi ci ay solution yu bari lu tollu ci 30 ba 90 fan, te duñu ñàkk lu bari ci diisaay bi (<1%) and no obvious signs of degradation, such as cracking, bubbling, or discoloration.

Lu weesu liñu mëna xeex substance chimik yi, plate fibre de verre yiy tere corrosion am nañu itam ay màndarga mekanik yu baax. Am nañu doole ju bari ci traction (50 - 150 megapascals) ak dooley bënndam (80 - 200 megapascals), ñu koy méngale ak yenn wen, waaye seen diisaay bi gëna woyof (densité bu 1.5 - 2.0 gram ci santimetre kib bu nekk, fekk asiye amna dëgëraay bu 7.8 gram ci santimetre kib bu nekk). Màndarga yii dañu wàññi njëgu dem bi ak dikk bi ak instalaasioŋ bi, suko defee ñu gëna yomba jëfandikoo ci projet yu mag. Seenug mbañeel ci mbëkkante (15 - 30 kilojoules ci meetar kaare bu nekk) dafa weesu itam bu mbir yu yomba dagg yu melni seramik wala weer, suko defee ñu mëna xeex mbëkkante yu ñu xamul wala jafe-jafe yu metti yu melni glaas.
