PC Steel Strand
01
Hloov kho unbonded prestressed steel strand rau cua zog, dej txuag thiab hydro-power
Khoom Taw Qhia
Lub 1x7 qauv "12.7mm, 15.20mm, 15.70mm, 17.80mm" unbonded prestressed steel strand yog tshwj xeeb prestressed steel bar nrog anti-corrosion roj thiab sheath. Cov khoom siv yog siv rau hauv kev txuag dej thiab kev siv hluav taws xob. Nyob rau hauv xyoo tas los no, cov phiaj xwm cua hluav taws xob tau nce zuj zus, kev tsim kho qhov siab ntawm cua zog ntauwd ncav cuag lossis tshaj 120m. Ntau thiab ntau pob zeb ntauwd nrog rau sab nraud prestressing tshuab yog siv unbonded prestressed steel strand. Cov khoom muaj qhov zoo ntawm qhov muaj zog corrosion kuj thiab qaug zog tiv thaiv, uas tuaj yeem txhim kho cua tsis kam thiab ua haujlwm ntev.
Raws li tus qauv ntawm JG / T 161-2016 Unbonded Prestressed Steel Strand, peb tsim cov qauv tsim kom yooj yim rau kev sim cov txheej txheem ntawm cov cuab yeej sheath tensile, txhim khu kev ua tau zoo, pab txhawb lub sheath kev ua tau zoo, ua qauv zoo ntawm cov sheath thiab txhim kho qhov zoo. kev ruaj ntseg ntawm qhov project.
Cov yam ntxwv ntawm cov khoom
Lub sab nrauv ntawm lub tshuab hluav taws xob ua vaj tse ntauwd yog siv rau cov hlau tsis sib txuas, lub thickness ntawm lub sheath thiab cov roj tuaj yeem tsim thiab tsim raws li cov kev xav tau ntawm cov neeg siv, qhov saum npoo ntawm lub sheath yog ntom thiab du, cov qauv tsim. ntawm steel strand tuaj yeem pom. Qhov saum npoo zoo tuaj yeem ua tau raws li qhov xav tau ntawm tsis muaj qhov cua, tsis muaj kev puas tsuaj, tsis muaj kab nrib pleb, tsis pom tseeb wrinkles, thiab lwm yam.
