Tlhokomeliso ea 'Maraka: Litšenyehelo tse ntseng li phahama tsa FRP le botsitso ba theko ea rona
Ka lebaka la likhohlano tsa morao-rao tse amang Iran, litheko tsa oli e tala lefatšeng ka bophara li eketsehile. Polyester Resin ke sehlahisoa sa mantlha se tlase sa petrochemical le lisebelisoa tsa mantlha tsa maqephe a FRP. Ka lebaka leo, theko ea eona e amana haholo le oli e tala, e lebisang ho nyoloheng ho tsoelang pele ha litheko tsa maqephe a FRP indastering eohle haufinyane.
Joaloka moetsi oa maqephe a FRP, re ne re boetse re lebelletse liphetoho tsena. Ka lebaka la mahlale a rona a polokelo ea thepa e tala, hajoale re khona ho boloka litheko tsa rona tsa mantlha ntle le ho nyolloa hanghang bakeng sa balekane ba rona.
Na u bona ho feto-fetoha ha theko e tšoanang 'marakeng oa hau?

Polyester resin ke sehlahisoa se tloaelehileng sa indasteri ea petrochemical, 'me liphetoho tsa eona tsa theko li amana haholo le litheko tsa oli e tala. Mokhoa oa phepelo ea phepelo e tjena: Oli e Krethehileng: Thepa e tala ea mantlha. Naphtha: Sehlahisoa sa ho hloekisa oli e tala. PX (para-xylene) & Benzene: E nkiloe ho naphtha cracking kapa reforming. PTA (e hloekisitsoeng terephthalic acid) & Ethylene glycol (EG) / Neopentyl glycol (NPG): PTA e hlahisoa ke oxidation ea PX. Ethylene glycol le neopenyl glycol le tsona haholo-holo li tsoa linthong tse tsoang ho petroleum (tse ling tsa neopenyl glycol li ka boela tsa lokisoa ka mokhoa oa isobutyraldehyde, empa mohloli o ntse o angoa ke litheko tsa matla). Polyester resin: E hlahisoa ke karabelo ea polycondensation ea PTA, ethylene glycol, neopenyl glycol, joalo-joalo.
