Galvanized steel strand hlau feem ntau yog hais txog cov tub ntxhais hlau lossis cov tswv cuab lub zog ntawm cov xaim xaim (tus txiv neej hlau).
A. Cov hlua hlau tau muab faib ua plaub yam raws li cov qauv hauv seem.
Qhia raws li daim duab hauv qab no qauv
B. GB steel strand muab faib ua tsib qib raws li nominal tensile zog: 1270MPa, 1370MPa, 1470MPa, 1570MPa, 1670MPa.
C. Nrog rau qhov sib txawv thickness ntawm zinc txheej nyob rau hauv galvanized steel strand, zinc txheej steel hlau nyob rau hauv GB steel strand muab faib ua peb theem: A, B thiab C.
1. Daim ntawv thov ntawm steel strand
Cov txheej muaj xws li galvanized, aluminium plated, coated nrog nylon lossis yas, thiab lwm yam. Galvanized steel strand hlau yog muab faib ua thawj txheej txheej thiab galvanized steel hlau tom qab kos cov txheej tuab, cov khoom siv ntawm cov txheej tuab yog qis dua cov hlau du. hlua, yuav tsum tau siv nyob rau hauv ib tug loj corrosive ib puag ncig.
2. Rau cov txheej txheem stranded hlau yuav tsum
1. Lub steel hlau nyob rau hauv strand (xws li central steel hlau) yuav tsum yog tib txoj kab uas hla, tib lub zog thiab tib zinc txheej txheej.
2. Txoj kab uas hla thiab nteg ntawm cov hlau strand yuav tsum tsis sib xws thiab tsis xoob tom qab txiav.
3. Cov hlau hlau nyob hauv txoj hlua yuav tsum nruj nruj, tsis muaj kev cuam tshuam, tawg thiab khoov.
Cov hlau strand yuav tsum ncaj, mos, me me residual kev nyuaj siab, thiab yuav tsum tsis txhob tshwm ∽ zoo tom qab nthuav.
5.1X3 qauv steel strand hlau thiab nyiaj siv ua haujlwm hauv av hlau tsis raug tso cai koom nrog, lwm yam steel strand hlau pob qij txha yuav tsum tau welded rau qhov sib koom ua ke, ob lub pob qij txha yuav tsum tsis pub tsawg tshaj 50m, kev sib koom ua ke yuav tsum tau kho los tiv thaiv corrosion.
3. Rhuav nro ntawm steel strand
Muaj ob txoj hauv kev los ntsuas qhov kev sib tsoo ntawm cov hlau strand
Txoj Kev 1: Ntsuas lub zog tawg ntawm tag nrho cov hlau strand.
Txoj Kev 2: Txhawm rau txiav txim siab tag nrho kev sib tsoo ntawm cov hlua hlau?
Raws li cov qauv hauv qab no:
Cov txiaj ntsig ntawm kev sib tsoo ntawm cov hlau xaim hauv txoj hlua = qhov tsawg kawg nkaus tawg nro ntawm txoj hlua X hloov pauv coefficient
Kev hloov pauv yam khoom?
Tus qauv 1X3 yog 1.08
1X7 qauv yog 1.08
1X19 qauv yog 1.11
1X37 qauv yog 1.17
4. Qhov zoo ntawm qhov chaw
1. Qhov saum npoo ntawm cov hlau hlau nyob rau hauv txoj hlua yuav tsum tsis txhob imprinted, khawb, tawg, flattened thiab nyuaj khoov tsis xws luag.
2. Qhov saum npoo ntawm txoj hlua yuav tsum tsis muaj roj, muaj kuab paug, dej thiab lwm yam impurities.
3. Strand split steel hlau nto ntawm galvanized txheej yuav tsum tsis tu ncua thiab nruam, tsis muaj tawg thiab tev tshwm sim. Txawm li cas los xij, qhov saum npoo ntawm zinc txheej tau tso cai kom muaj me me ntawm flash thiab dawb nyias txheej thiab xim sib txawv.
5. Marking ntawm steel strand
Cim piv txwv: qauv 1X7, txoj kab uas hla 6.0mm, tensile zog 1370M Pa, Class A zinc txheej steel strand cim: 1X7-6.0-1370-A-YB/T 5004-2012
Packing, marking thiab daim ntawv pov thawj zoo
Kev ntim khoom, kos npe thiab daim ntawv pov thawj zoo ntawm steel strand yuav tsum ua raws li GB / T 2104.
Feem ntau, txhua yam steel strand hlau yuav tsum tau xa hauv lub tais. Raws li kev pom zoo ntawm ob tog, cov ntawv pov thawj noo noo, linen, yas woven daim ntaub thiab lwm yam khoom ntim ntxiv tuaj yeem muab ntxiv.
