The Best Steel Prestressed Engineering Strand
Prestressed steel strand ke thapo ya tshepe e hahelletsweng e bopilweng ka dithapo tsa tshepe tse 2, 3, 7 kapa 19 tse matla haholo, mme e bile kalafo ya ho imolla kgatello ya maikutlo (phekolo ya botsitso), e loketseng konkreite e hatelletsweng pele kapa merero e tshwanang.
Litšobotsi tse ka sehloohong tsa likhoele tsa tšepe tse hatelitsoeng pele ke matla a phahameng, ts'ebetso e ntle ea ho phomola, 'me e batla e otlolohile ha e phutholoha. Kereiti e tloaelehileng ea matla ke 1860 MPa, 'me ho na le limaraka tsa matla tse kang 1720, 1770, 1960, 2000, le 2100 MPa. Matla a lihlahisoa a tšepe ena a boetse a phahame haholo.
Thepa ea tšepe e nang le k'habone e phahameng e huleloa ka har'a terata ea tšepe ka mor'a ho phekoloa ka holim'a metsi, ebe palo e itseng ea lithapo tsa tšepe li sotheha hore e be likhoele ho latela sebopeho sa likhoele tsa tšepe, ebe li thehoa ka mokhoa oa ho tsitsisa khatello ea kelello. E le ho eketsa nako e telele, terata ea tšepe e ka ba le tšepe ea tšepe kapa e se nang tšepe kapa ea ho roala, e kang galvanizing, epoxy coating, joalo-joalo E le ho eketsa matla a tlamahano le konkreite, bokaholimo bo ka ba le li-nicks joalo-joalo. Mohatla o entsoeng ka tšepe o entsoeng ka prestressed o kena ts'ebetsong ea ho hatella hlobo ka mor'a ho ts'oaroa, sebopeho se teteaneng 'me lera la bokaholimo le loketse ho ts'oaroa. Ho etsa likhoele tsa tšepe tse sa tlamisoang (likhoele tsa tšepe tse sa tlamisoang) sebelisa likhoele tse tloaelehileng tsa tšepe tse hatelitsoeng pele, tse tlositsoeng ka mafura a anti-corrosion kapa boka ba parafine, ebe o phuthetsoe ka polyethylene e phahameng haholo (HDPE).
