Folasaga o oloa
Hot-Dipped Galvanized PC Strand low relaxation prestressed u'amea u'amea ua faia e fitu uaea u'amea lapotopoto lapotopoto uaea ma lelei tetee corrosion, lea e mafai ona faalautele lelei le ola o vaega i le tulaga o siosiomaga corrosive e pei o le gataifale, lea ua aloaia e pei o. ose faiga aoga ole puipuiga ole a'a ile taimi nei ma faavaomalo.
O lenei tulaga faʻatatau e faʻaoga i le alalaupapa o le uaea, vaega faʻamautu faʻalavelave, siiina poʻo le faʻapipiʻiina o vaega faʻalavelave o fale ma isi fausaga faʻapipiʻi, lea e le faʻaaogaina saʻo i fausaga sima, lautele: 12.7mm, 15.mm, 15.7mm, 17.8mm, malosi. vasega: 1770MPa, 1860MPa, 1960MPa. (o lo'o ta'ua mulimuli ane o le "mea uamea").
O le fausaga o le 1x7, 1x19 vevela fa'aulu fa'ameamea prestressed u'amea fa'asologa oloa, le malosi tensile lea e mafai ona o'o atu i le 1860MPa ma fa'amatalaga tutusa e pei o le u'amea u'amea PC manino & lapotopoto i tulaga o tulaga fa'atinoga acc.to GB/T 33363, ASTM A416, EN10138, BS ma le NFA35-035 ma isi.
Oloa Fa'ailoga
O le oloa e mafai ona gaosia e tusa ai ma talosaga o le zinc coating mai tagata faʻatau, zinc coating e mafai ona oʻo atu i le 250 gsm poʻo luga atu, o le tutusa o le zinc coating layer e 3-4 taimi e aunoa ma le faʻaalia o le kopa, ma o le pipii e le malepe ma e le paʻu. i lalo o le tulaga e ala i le viliina o li'o 8 pe a uma ona ufiufi le zinc.
Faʻalagolago i meafaigaluega faʻapitoa a le kamupani, e mafai ona tatou mamanuina le faagasologa galvanized e faʻafetaui manaoga faʻapitoa o tagata faʻaoga i luga o le zinc layer quality, surface quality, etc.
Fa'atusatusaina i le PC uamea strand e aunoa ma le ufiufi ma u'amea PC uamea strand, o le muamua na aliali mai elea mumu ina ua uma le su'ega masima mo le 24 itula.
Suiga faʻataʻitaʻiga o le uʻamea uʻamea PC e aunoa ma le faʻapipiʻiina ma le uʻamea uʻamea PC uʻamea pe a uma le 21 aso ole suʻega faʻafefe masima e pei ona taua i lalo,
Talosaga Oloa
1) E mafai ona faʻaaogaina oloa ile inisinia faufale ma faʻainisinia lagolago auala maina koale i lalo ole tulaga faigata o le siosiomaga.
2) I tausaga talu ai nei, ua faʻaaogaina foi i le fanua o le malosi o le matagi. "1x7-medium 21.6mm, Large-Sized Hot-Dipped Galvanized PC Steel Strand", lea na faʻaaogaina i le lalolagi muamua "160m, low-wind-speed prestressed frame wind turbine tower", faʻatasi ai ma le gafatia maualuga, lea e faʻatautaia e faʻaleleia atili. le malosi o le matagi o le olo. Faatasi ai ma le lelei o le corrosion resistance, lea e mafai ona faʻalauteleina ai le ola tautua o le olo.
Ole lalolagi muamua ole 160m maualalo le saoasaoa ole matagi fa'ata'ita'i olo maualuga i Shandong
