Fiberglass ey'omutindo ogwa waggulu Anti-Corrosion Panel

FRP anti-corrosion boards bintu bya mulembe ebikoleddwa mu ngeri ey’enjawulo okusobola okuwa eddagala erisingako era tezeetaagisa mu mbeera enzibu mu makolero n’obutonde. Ekoleddwa mu matrices za resin ezikola obulungi-n’ebintu ebinyweza fiber y’endabirwamu, ebipande bino bigatta amaanyi g’ebyuma n’okuziyiza okukulukuta okw’enjawulo, ne biwa eky’okuddako ekiwangaala okusinga ebintu eby’ennono ng’ebyuma, embaawo, oba seminti mu mbeera ezikulukuta.

Ensengekera enkulu eya FRP anti-corrosion boards erimu layers ssatu enkulu: layeri ya gel coat ekuuma, layer enyweza fiber y’endabirwamu, ne layer ya resin edda emabega. Layer ya gel coat, etera okukolebwa mu unsaturated polyester oba vinyl ester resin, ekola ekiziyiza ekisinga ebweru, ekiwa ekifo ekiweweevu, ekitaliimu butuli-ekiziyiza okuyingira kw’eddagala n’okuvunda kwa UV. Wansi waayo, ebintu ebinyweza obuwuzi bw’endabirwamu bitegekeddwa mu ngeri y’ebitanda oba emifaliso egylukibwa, ne biwa olubaawo amaanyi ag’ebyuma n’okukakasa nti lusobola okugumira emigugu gy’enzimba n’okukubwa. Resin edda emabega, etera okuteekebwamu ebiziyiza okukulukuta, eyongera ku buwangaazi bw’olubaawo okutwalira awamu n’okunywerera wakati wa layers. Abakola ebintu basobola okulongoosa obuwanvu bwa buli layeri (okuva ku mm 2 okutuuka ku mm 15) okusinziira ku byetaago ebitongole eby’okukozesa, ne batuuka ku bbalansi wakati w’obuzito n’omulimu.

Ekimu ku bintu ebisinga okwewuunyisa ku fiberglass composite anti-corrosion plates kwe kuziyiza kwazo okw’amaanyi okw’eddagala. Ziraga okugumiikiriza okulungi ennyo ebintu eby’enjawulo ebivunda, omuli asidi (nga asidi wa salufuriki ne asidi wa haidrochloric), base (sodium hydroxide, amazzi ga ammonia), eminnyo, ebizimbulukusa, n’amazzi amakyafu ag’amakolero. Okwawukana ku bipande by’ebyuma ebyandibadde bifuuse enfuufu oba okukulukuta nga bifunye eddagala ng’eryo, ebipande bya fiberglass bisobola okukuuma obulungi bw’enzimba yaabyo ne bwe biba bimaze okukwatagana okumala ebbanga. Obuziyiza buno obw’eddagala bukakasiddwa okuyita mu kugezesebwa okukakali, gamba ng’okugezesa okugumiikiriza eddagala okusinziira ku mutindo gwa ASTM D543, nga sampuli zinnyikiddwa mu biwujjo eby’enjawulo okumala ennaku eziwera 30 ku 90, nga tezikendeera nnyo mu buzito (<1%) and no obvious signs of degradation, such as cracking, bubbling, or discoloration.

Ng’oggyeeko okuziyiza eddagala, fiberglass composite anti-corrosion plates nazo zirina eby’ebyuma ebirungi ennyo. Zirina amaanyi g’okusika amangi (50 - 150 megapascals) n’amaanyi g’okubeebalama (80 - 200 megapascals), ezigeraageranyizibwa ku byuma ebimu, naye nga zirina obuzito obutono ennyo (density ya 1.5 - 2.0 grams buli cubic centimeter, ate ekyuma kirina density ya 7.8 grams buli cubic centimeter). Engeri eno etali ya maanyi ekendeeza ku ntambula n’okussaako, ekizifuula eziddukanyizibwa mu pulojekiti ennene-. Obuziyiza bwazo obw’okukuba (15 - 30 kilojoules buli square meter) era busukka obw’ebintu ebimenyamenya nga seramiki oba endabirwamu, okukakasa nti zisobola okugumira okutomeragana okutasuubirwa oba embeera y’obudde enzibu nga laddu.
