Pipe ea Epoxy ea FRP
Tlhaloso ea Sehlahisoa
Phaephe ea epoxy ea FRP e tsejoa ka molao e le phaephe ea Glass Fiber Reinforced Epoxy (GRE). Ke phaephe ea thepa e kopaneng e sebetsang hantle, e entsoeng ka ho sebelisa mokhoa oa ho kobeha ha filament kapa ts'ebetso e ts'oanang, ka likhoele tsa khalase tse matla haholo e le thepa e matlafatsang le resin ea epoxy e le matrix. Melemo ea eona ea mantlha e kenyelletsa ho hanyetsa ho ts'enyeha ho ikhethang (ho felisa tlhoko ea liphahlo tse sireletsang), boima bo bobebe bo kopantsoeng le matla a phahameng (ho nolofatsa ho kenngoa le ho tsamaisoa), conductivity e tlase haholo ea mocheso (ho fana ka insulation ea mocheso le poloko ea matla), le lebota le boreleli, le sa holang ka hare. Litšobotsi tsena li etsa hore e be sebaka se setle sa liphaephe tsa setso makaleng a kang peterole, lik'hemik'hale, boenjiniere ba likepe, insulation ea motlakase le kalafo ea metsi.
Likarolo tsa Sehlahisoa
Pipe ea Epoxy ea FRP (Glass Fiber Reinforced Epoxy, kapa GRE) e fana ka motsoako o motle oa thepa ha e bapisoa le thepa ea setso:
1. Khanyetso e Ikhethang ea Ts'enyeho
- Tšireletso ea Lik'hemik'hale: E hanela haholo mefuta e mengata ea lintho tse senyang, ho kenyeletsoa li-acid, li-alkali, letsoai, likhoerekhoere le metsi a leoatle.
- Ha e hloke tlhokomelo: Ha e hloke masela a sireletsang a ka hare kapa a kantle kapa tšireletso ea cathodic, e leng se felisang tlhokomelo le kotsi e amanang le mafome.
2. Boima bo bobebe le Matla a Phahameng
- Botebo bo Fokotseng: E boima ba 1/4 ho isa ho 1/8 feela ea phaephe ea tšepe, e nolofatsa haholo thepa ea ho tsamaisa thepa, ho e phahamisa le ho e kenya, e leng se fokotsang litšenyehelo tsa projeke ka kakaretso.
- Matla a Phahameng a Mekaniki: E na le matla a ho tsitlella, ho kobeha le ho otla, e khona ho sebetsana le khatello e phahameng ea ts'ebetso le meroalo ea kantle.
3. Litšobotsi tse Hloahloa tsa Haeteroliki
- Bore e Boreledi: Bokaholimo ba kahare bo na le khohlano e tlase haholo, e fokotsang tahlehelo ea hlooho ea mokelikeli le tšebeliso ea matla a ho pompa ha e bapisoa le liphaephe tsa tšepe.
- Ho se Sekase: Lebota le boreleli le hanela ho khomarela ha sekala, seretse le ho silafatsa lintho tse phelang (joalo ka kholo ea leoatle), le boloka ts'ebetso e phahameng ea phallo ha nako e ntse e ea.
4. Thepa ea Mocheso le Motlakase
- Ho Thibela Mocheso: E na le phallo e tlase haholo ea mocheso (hoo e ka bang 1% ea tšepe), e fana ka ho thibela mocheso ho fokotsa tahlehelo kapa keketseho ea mocheso bakeng sa mokelikeli o fetisoang.
- Ho Thibela Motlakase: E fana ka thepa e ntle ea ho thibela motlakase, e leng se etsang hore e bolokehe ebile e loketse ho sebelisoa maemong a motlakase le a puisano.
5. Ho Tšoarella le Litšenyehelo tse Tlase tsa Potoloho ea Bophelo
- Bophelo bo Bolelele ba Tšebeletso: E etselitsoe bophelo ba tšebeletso ba lilemo tse 25 kapa ho feta tlas'a maemo a tloaelehileng a ts'ebetso.
- Tlhokomelo e Nyenyane: Ka lebaka la ho hanyetsa mafome le ho hola ha yona, sistimi ha e hloke tlhokomelo ya kamehla, e leng se fellang ka ditjeo tse tlase tsa potoloho ya bophelo.
