Steel strand-txhawb ntxiv xya-hlau hlua

Steel Strand yog cov khoom lag luam steel muaj cov hlau ntau ntau sib ntswg sib dhos ua ke. Cov saum npoo ntawm cov hlau hlau tuaj yeem muab tso nrog galvanized txheej, zinc-aluminium txheej, tooj sau plating txheej, epoxy co txheej, thiab lwm yam raws li xav tau.
Khoom siv: steel
Cov qauv: muaj ntau cov hlau hlau ntau ntswj ua ke
Kev faib tawm: Prestressed, unbonded, galvanized steel strand, thiab lwm yam.
Cov Txheej Txheem Txheej Txheem Ntau Lawm: Ib Leeg Hlau Raug Thiab Ntaus Hlau Ntaus Hlau
Daim Ntawv Thov: Thauj-bear-bearing cable, nro hlau xaim, kev txhawb nqa cov tub ntxhais, hauv av

(1) kev faib tawm los ntawm kev siv
Prestressed steel strand, (hluav taws xob) galvanized steel strand thiab stainless hlau Strand. Prestressed steel strand coated nrog anti-corrosion roj lossis paraffin thiab tom qab ntawd qhwv nrog HDPODE yog hu ua Unbonded Prestressed Steel Strand. Prestressed steel strand kuj tseem ua los ntawm galvanized los yog galvanized aluminium alloy steel hlau.
(2) Kev faib tawm los ntawm cov khoom siv khoom
Hlau STAD, txhuas clad steel hlau strand thiab stainless hlau Strand. (3) kev faib tawm los ntawm cov qauv
Prestressed steel strands tuaj yeem faib ua 7-hlau, 2-hlau, 3-hlau cov xov hlau, thiab feem ntau siv yog 7-hlau qauv.
Galvanized steel strands thiab txhuas clad steel stands rau fais fab siv kuj tseem muab faib ua 2, 3, 37 thiab feem ntau siv yog 7-hlau qauv.
(4) kev faib tawm los ntawm txheej deg
Nws tuaj yeem muab faib ua (du) steel stands, galvanized steel strands, tooj liab-coated steel strands, yas-coated steel strands, thiab lwm yam.
Kev tsim kev tsim khoom raug muab faib ua ib qho-hlau raug thiab cov hlau ntaus hlau. Thaum ua ib leeg-xov hlau, (khaub thuas) xaim hluav taws xob siv. Depending on the different materials of the product, it can be high-carbon steel wire rods, stainless steel wire rods or medium-low carbon steel wire rods. Yog tias Galvanizing yog qhov yuav tsum tau ua, electroplating lossis kub-dip yuav tsum tau ua rau ntawm ib lub xaim hlau. Nyob rau hauv kev tsim khoom txheej txheem ntawm stranded hlau, lub tshuab stranding yog siv los ntswj ntau tus hlau xaim rau cov khoom. Prestressed steel strands tseem yuav tsum tau ua kom ruaj khov tom qab sib sau ua ke. Cov khoom kawg yog feem ntau sau rau ntawm lub reel lossis reel-tsawg dua.
Galvanized Steel Strands feem ntau yog siv rau cov xov tooj neeg xa xov, cov xov hlau lossis cov qauv hauv av, lossis cov qauv coj ua hauv kev tsim kho vaj tsev. Cov neeg siv hluav taws xob prestressed steel tau tsis muaj txiaj ntsig zoo nkauj (galvanized steel Feem ntau siv hauv pem teb slabs, hauv paus engineering, thiab lwm yam.

Kev tswj lub zog nruj ntawm cov standressed steel strand tsim tsim yog hais txog qhov nro ntawm lub dav hlau clamp tom qab prestressing tiav. Yog li ntawd, thaum xam cov theoretical elongation ntawm lub prestressed steel cov strand, qhov deb ntawm lub kauj ruam ntawm ob qho ntawm cov hlau sib tw yuav tsum tau siv ntev ntawm cov hlau Strand. Txawm li cas los xij, thaum lub sij hawm prestressing, lub zog tswj kev quab yuam ntawm lub steel Strand yog tswj hwm ntawm Jack Carnor. Yog li ntawd, rau qhov yooj yim ntawm kev tswj hwm thiab kev xam, qhov deb ntawm cov cuab yeej siv hluav taws xob ntev ntawm lub siab ntev ntawm lub theoretical elongation ntawm prestressed steel strand. Thaum lub sij hawm prestressing ntawm cov hlau strand, feem ntau ntawm cov spred steel strand yog qhwv los ntawm lub thauj tog rau nkoj thiab Jack. Qhov nro elongation ntawm cov steel sib zog tsis tuaj yeem ntsuas ncaj qha rau ntawm cov steel strand. Yog li ntawd, qhov nro elongation ntawm cov hlau stand tsuas yog suav tau los ntawm kev ntsuas lub piston stroke jack. Txawm li cas los xij, tus nqi ntawm thauj tog rau nkoj rov qab thaum tag nrho cov txheej txheem ntawm prestressing cov hlau strand yuav tsum tau txiav. Lub thauj khoom-coj muaj peev xwm ntawm cov hlau Strand yuav tsum yog 4-6 lub sij hawm tag nrho cov quab yuam tag nrho.
