1) Khanyetso ea ho Sila le Bophelo bo Bolelele ba Tšebeletso

Liphaephe tsa FRP li na le khanyetso e ntle ea ho bola, li hanela khanyetso e tsoang ho li-acid, alkali, letsoai, metsi a leoatle, metsi a litšila a oli, mobu o senyang le metsi a ka tlas'a lefatše—ke hore, lik'hemik'hale tse ngata. Li boetse li bontša khanyetso e ntle ho li-oxide tse matla le li-halogen. Ka hona, nako ea bophelo ea liphaephe tsena e atolosoa haholo, ka kakaretso e feta lilemo tse 30. Litekanyetso tsa laboratori li bontša horeLiphaephe tsa FRPe ka ba le bophelo ba tšebeletso ba lilemo tse fetang 50. Ka lehlakoreng le leng, liphaephe tsa tšepe libakeng tse tlaase, tse nang le alkali ea letsoai, kapa libaka tse ling tse senyang haholo li hloka tlhokomelo kamora lilemo tse 3-5 feela, ka bophelo ba tšebeletso ba lilemo tse ka bang 15-20 feela, le litšenyehelo tse phahameng tsa tlhokomelo mehatong ea morao ea ts'ebeliso. Phihlelo ea ts'ebetso ea lehae le ea machabeng e pakile hore liphaephe tsa FRP li boloka 85% ea matla a tsona kamora lilemo tse 15 le 75% kamora lilemo tse 25, ka litšenyehelo tse tlase tsa tlhokomelo. Boleng bona ka bobeli bo feta sekhahla se tlase sa ho boloka matla se hlokahalang bakeng sa lihlahisoa tsa FRP tse sebelisoang indastering ea lik'hemik'hale kamora selemo se le seng sa ts'ebeliso. Bophelo ba ts'ebeletso ba liphaephe tsa FRP, e leng taba e tšoenyang haholo, bo pakiloe ke data ea liteko ho tsoa lits'ebetsong tsa 'nete. 1) Litšobotsi tse Hloahloa tsa Hydraulic: Liphaephe tsa FRP (fiberglass reinforced plastic) tse kentsoeng US lilemong tsa bo-1960 li 'nile tsa sebelisoa ka lilemo tse fetang 40' me li ntse li sebetsa ka tloaelo.

2) Litšobotsi tse ntle tsa Hydroelekthara

Mabota a ka hare a boreleli, khohlano e tlase ea haeteroliki, poloko ea matla, le ho hanyetsa ho hola le mafome. Liphaephe tsa tšepe li na le mabota a ka hare a thata, e leng se fellang ka khohlano e phahameng e eketsehang ka potlako ka ho hola, e leng se lebisang tahlehelong e eketsehileng ea khanyetso. Bokaholimo bo thata bo boetse bo fana ka maemo a ho beoa ha sekala. Leha ho le joalo, liphaephe tsa FRP li na le khohlano ea 0.0053, e leng 2.65% ea liphaephe tsa tšepe tse se nang sekoli, 'me liphaephe tse kopantsoeng tsa polasetiki tse matlafalitsoeng li na le khohlano ea 0.001 feela, e leng 0.5% ea liphaephe tsa tšepe tse se nang sekoli. Ka hona, hobane lebota le ka hare le lula le boreleli nakong eohle ea bophelo ba lona, ​​khohlano e tlase ea khanyetso e fokotsa tahlehelo ea khatello haholo ka har'a phaephe, e boloka matla, e eketsa bokhoni ba ho tsamaisa, 'me e tlisa melemo e meholo ea moruo. Bokaholimo bo boreleli bo boetse bo thibela ho beoa ha litšila tse kang libaktheria, sekala le boka, ho thibela tšilafalo ea sebaka se tsamaisoang.

3) Ho Thibela Botsofali, Ho Hanela Mocheso, le Ho Hanela ho Hoama

Liphaephe tsa fiberglass li ka sebelisoa ka nako e telele ka har'a mocheso oa -40 ho isa ho 80℃. Li-resin tse hanelang mocheso o phahameng tse nang le mekhoa e khethehileng li ka sebetsa ka mokhoa o tloaelehileng esita le mochesong o ka holimo ho 200℃. Bakeng sa liphaephe tse sebelisoang kantle ka nako e telele, li-absorber tsa ultraviolet li eketsoa holim'a bokaholimo ba kantle ho felisa mahlaseli a ultraviolet le ho liehisa botsofali.

4) Ho tsamaisa mocheso ka tlase, ho kenya mocheso hantle le thepa ea ho kenya mocheso ka motlakase

Ho tsamaisa mocheso ha thepa ea liphaephe tse sebelisoang hangata ho bontšoa ho Tafole ea 1. Ho tsamaisa mocheso ha liphaephe tsa fiberglass ke 0.4 W/m·K, hoo e ka bang 8‰ ea tšepe, e leng se fellang ka ts'ebetso e ntle ea ho kenya mocheso. Fiberglass le thepa e 'ngoe e seng ea tšepe ha li tsamaise mocheso, ka khanyetso ea ho kenya mocheso ea 10¹² ho isa ho 10¹⁵ Ω·cm, e fanang ka ho kenya mocheso ho babatsehang ha motlakase, e leng se etsang hore li be ntle bakeng sa tšebeliso libakeng tse nang le phetiso ea matla a mangata le likhokahano tsa mohala le libaka tse kotsing ea ho otloa ke lehalima.

5) E bobebe, matla a phahameng a khethehileng, le khanyetso e ntle ea mokhathala

Bongata bapolasetiki e matlafalitsoeng ka fiberglass (FRP)e pakeng tsa 1.6 le 2.0 g/cm³, e leng makhetlo a 1-2 feela a tšepe e tloaelehileng le hoo e ka bang 1/3 ea aluminium. Hobane likhoele tse tsoelang pele ho FRP li na le matla a ho tensile le modulus e tenyetsehang, matla a eona a mechini a ka fihla kapa a feta a tšepe e tloaelehileng ea carbon, 'me matla a eona a itseng a makhetlo a mane a tšepe. Tafole ea 2 e bontša papiso ea bongata, matla a ho tensile, le matla a itseng a FRP le litšepe tse 'maloa. Lisebelisoa tsa FRP li na le khanyetso e ntle ea mokhathala. Ho hloleha ha mokhathala linthong tsa tšepe ho hlaha ka tšohanyetso ho tloha kahare ho ea ka ntle, hangata ntle le temoso ea pele; leha ho le joalo, linthong tse kopantsoeng tse matlafalitsoeng ke faeba, khokahano pakeng tsa likhoele le matrix e ka thibela ho ata ha mapetso, 'me ho hloleha ha mokhathala kamehla ho qala ho tloha ntlheng e fokolang ka ho fetisisa thepa. Liphaephe tsa FRP li ka hlophisoa hore li be le matla a fapaneng a potoloho le a axial ka ho fetola mokhoa oa fiber ho lumellana le boemo ba khatello, ho latela matla a potoloho le a axial.

6) Ho hanyetsa ho tsofala hantle

Ho ya ka diteko tse amehang, tlasa maemo a tshwanang le kamora didikadikwe tsa mojaro tse 250,000, ho kgathala ha diphaephe tsa tshepe e ne e le hoo e ka bang 8.4 mm, diphaephe tsa samente ya asbestos e ka bang 5.5 mm, diphaephe tsa konkreite tse ka bang 2.6 mm (tse nang le sebopeho se tshwanang sa bokahodimo ba kahare le PCCP), diphaephe tsa letsopa tse ka bang 2.2 mm, diphaephe tsa polyethylene tse nang le bongata bo boholo ba tsona e ka bang 0.9 mm, ha diphaephe tsa fiberglass di kgathala ho fihlela ho 0.3 mm feela. Ho kgathala ha bokahodimo ha diphaephe tsa fiberglass ho honyenyane haholo, ke 0.3 mm feela tlasa meroalo e boima. Tlasa kgatello e tlwaelehileng, ho kgathala ha sekgahla hodima lesela le kahare la phaephe ya fiberglass ha ho bohlokwa. Lebaka ke hobane lesela le kahare la phaephe ya fiberglass le entswe ka resin e nang le dikahare tse ngata le materase a faeba ya khalase e kgabetsweng, mme lera la resin hodima bokahodimo bo kahare le sireletsa ka katleho kgahlanong le ho pepesehela faeba.

7) Bokgoni bo botle ba ho qapa

Fiberglass ke thepa e kopaneng eo mefuta ea eona ea thepa e tala, litekanyo le litlhophiso li ka fetoloang ho ikamahanya le maemo a fapaneng a mosebetsi. Liphaephe tsa fiberglass li ka etsoa le ho etsoa ho fihlela litlhoko tse fapaneng tse ikhethileng tsa basebelisi, joalo ka mocheso o fapaneng, sekhahla sa phallo, likhatello, botebo ba lepato le maemo a mojaro, e leng se fellang ka liphaephe tse nang le khanyetso e fapaneng ea mocheso, litekanyetso tsa khatello le maemo a ho satalla.Liphaephe tsa fiberglassHo sebelisa li-resin tse entsoeng ka mokhoa o ikhethileng tse hanelang mocheso o phahameng ho ka boela ha sebetsa ka tloaelo mochesong o fetang 200℃. Lisebelisoa tsa liphaephe tsa fiberglass li bonolo ho li etsa. Li-flange, li-elbow, li-tee, li-reducer, jj., li ka etsoa ka mokhoa o sa reroang. Mohlala, li-flange li ka hokahanngoa le flange efe kapa efe ea tšepe ea khatello le bophara bo tšoanang ba phaephe bo lumellanang le maemo a naha. Li-elbow li ka etsoa ka lehlakoreng lefe kapa lefe ho latela litlhoko tsa sebaka sa kaho. Bakeng sa thepa e meng ea phaephe, li-elbow, li-tee, le lisebelisoa tse ling li thata ho li etsa ntle le likarolo tse tloaelehileng tsa litlhaloso tse boletsoeng.

8) Litšenyehelo tse tlase tsa kaho le tlhokomelo

Liphaephe tsa fiberglass li bobebe, li matla haholo, li bonolo ho li sebelisa, li bonolo ho li kenya, ha li hloke lelakabe le bulehileng, li netefatsa kaho e sireletsehileng. Bolelele ba phaephe e le 'ngoe bo fokotsa palo ea manonyeletso morerong 'me bo felisa tlhoko ea thibelo ea mafome, ho thibela litšila, ho thibela ho ruruha le mehato ea ho boloka mocheso, e leng se fellang ka litšenyehelo tse tlase tsa kaho le tlhokomelo. Tšireletso ea cathodic ha e hlokehe bakeng sa liphaephe tse patiloeng, e leng se ka bolokang ho feta 70% ea litšenyehelo tsa tlhokomelo ea boenjiniere.
