Sekoahelo sa FRP
Tlhaloso ea Sehlahisoa
Li-flange tsa FRP (Fiberglass Reinforced Plastic) ke lihokelo tse bōpehileng joaloka lesale tse sebelisetsoang ho kopanya liphaephe, li-valve, lipompo, kapa lisebelisoa tse ling ho theha tsamaiso e feletseng ea liphaephe. Li entsoe ka thepa e kopaneng e nang le likhoele tsa khalase e le thepa e matlafatsang le resin ea maiketsetso e le matrix. Li etsoa ka mekhoa e kang ho bopa, ho beha ka letsoho, kapa ho phunya likhoele.
Likarolo tsa Sehlahisoa
Ka lebaka la sebopeho sa tsona se ikhethang, li-flange tsa FRP li fana ka melemo e meholo ho feta li-flange tsa tšepe tsa setso:
- Ho Hanela ho Tshabala ho Hlollang: Tšobotsi e hlahelletseng ka ho fetisisa ea li-flange tsa FRP ke bokhoni ba tsona ba ho hanela ho shala ho tsoa mefuteng e fapaneng ea lik'hemik'hale, ho kenyeletsoa li-acid, li-alkali, letsoai le li-solvent tsa tlhaho. Sena se etsa hore li sebelisoe haholo libakeng tseo maro a senyang a tsamaisoang ho tsona, joalo ka indastering ea lik'hemik'hale, peterole, tšepe, motlakase, meriana le lijo.
- E bobebe le Matla a Phahameng: Botenya ba FRP hangata ke karolo ea 1/4 ho isa ho 1/5 feela ea tšepe, leha ho le joalo matla a eona a ka bapisoa. Sena se etsa hore ho be bonolo ho li tsamaisa le ho li kenya, 'me se fokotsa moroalo o akaretsang tsamaisong ea liphaephe.
- Ho Sireletsa Motlakase ho Molemo: FRP ke thepa e sa tsamaiseng motlakase, e fang di-flange tsa FRP thepa e ntle ya ho sireletsa motlakase. Sena se bohlokwa dibakeng tse itseng ho thibela ho bola ha dikhemikhale tsa motlakase.
- Ho Tenyetseha ha Moralo o Phahameng: Ka ho fetola foromo ea resin le tokisetso ea likhoele tsa khalase, li-flange tsa FRP li ka etsoa ka mokhoa o ikhethileng ho fihlela litlhoko tse itseng tsa mocheso, khatello le ho hanyetsa mafome.
- Litšenyehelo tse Tlase tsa Tlhokomelo: Li-flange tsa FRP ha li ruse kapa ha li teteane, e leng se etsang hore bophelo ba tšebeletso e be telele 'me se fokotsa haholo litšenyehelo tsa tlhokomelo le ho nkela sebaka.
Mofuta oa Sehlahisoa
Ho latela mokhoa oa bona oa tlhahiso le sebopeho sa sebopeho, li-flange tsa FRP li ka aroloa ka mefuta e 'maloa:
- Flange ea Karolo e le 'Ngoe (E Kopanetsoeng): Mofuta ona o entsoe e le yuniti e le 'ngoe e nang le 'mele oa phaephe, e fanang ka sebopeho se tiileng se loketseng lits'ebetso tsa khatello e tlase ho isa ho e mahareng.
- Flange e Lokolohileng (Flange e Kopantsoeng ea Matheka): E entsoe ka lesale la flange le hlephileng, le potolohang ka bolokolohi le ntlha e tsitsitseng ea stub holim'a phaephe. Moralo ona o nolofalletsa ho kenngoa, haholo-holo likhokahanong tsa lintlha tse ngata.
- Flange e Foufetseng (Flange e se nang letho/Sekoahelo sa ho Qetela): E sebelisetsoa ho koala pheletso ea phaephe, hangata bakeng sa tlhahlobo ea sistimi ea liphaephe kapa ho boloka sebopeho.
- Sekotjana sa Sokete: Phaephe e kenngwa ka hara mokoti o ka hare wa flange mme e hokahantswe ka mokhoa o sireletsehileng ka ho kopanya kapa ho phetholla ha sekhomaretsi, ho netefatsa tshebetso e ntle ya ho kwala.

Bakeng sa masoba a maholo kapa litlhaloso tse ikhethileng, ka kopo ikopanye le 'na bakeng sa ho iketsetsa.
Lisebelisoa tsa Sehlahisoa
Ka lebaka la ho hanyetsa mafome ka tsela e ikhethang le matla a bobebe, li-flange tsa FRP li sebelisoa haholo ho:
- Indasteri ea Lik'hemik'hale: Bakeng sa liphaephe tse tsamaisang lik'hemik'hale tse senyang tse kang li-acid, li-alkali le letsoai.
- Boenjiniere ba Tikoloho: Ka ho phekola metsi a litšila le lisebelisoa tsa ho tlosa khase ea flue.
- Indasteri ea Motlakase: Bakeng sa litsamaiso tsa metsi a pholileng le a ho tlosa sulfurization/denitrification lifemeng tsa motlakase.
- Boenjiniere ba Likepe: Litsamaisong tsa ho tlosa letsoai metsing a leoatle le liphaephe tsa likepe.
- Liindasteri tsa Lijo le Meriana: Bakeng sa mela ea tlhahiso e hlokang bohloeki bo phahameng ba thepa.
