Gret 8.8 Hot Dip Galvanised Hex Bolts bilong Sola na Steel Straksa
Bilong wanem Materiel Seleksen i bikpela samting moa long "8.8" mak
Taim yu wok long painim samtingGret 8.8 hot dip galvanis heks boltlong ol sola fam o ol 'steel structures', planti baia i save lukluk tasol long 'grade marking'.
Tasol long ol projek bilong 'real-world, tupela komon feilia i save kamap yet:
Rusting hariap
Wantu bolt i bruk aninit long lod
As bilong dispela em i isi:
planti taim ol i no save tingim ain samting i stap baksait long bolt.
Long Handan Dongchao Hardware, mipela i save mekim narapela kain wok.
Mipela i no save salim tasol wanpela "Gred 8.8 bolt" - mipela i save wokim ol samting bilong en.
Wanem samting i mekim wanpela gutpela Gret 8.8 HDG Bolt?
Wanpela trupela hai-pefomens bolt i mas bungimtripela bikpela kondisen:
Stebol kemikel komposisen
Kontrolim hat tritmen bekim
Pasin bilong sakim 'hydrogen embrittlement' bihain long 'galvanizing'
Dispela em i as na mipela i save yusim tasol'traceable virgin steel wire rod', i no ol pipia we ol i bin yusim gen.
Ol bikpela samting bilong mipela long Gret 8.8 Bolt
1. SWRCH35K & 10B21 – Gutpela Balens bilong ol Sola Projek
Long planti sola mounting sistem na ol standet straksa aplikesen, mipela i rekomendim:
SWRCH35K (JIS G 3507 Cold Heading Steel)
10B21 (Boron Steel)
Bilong wanem ol dispela samting i wok gut moa:
Gutpela kol heding samting
Strongpela strong oltaim
Yunifom intanel grein straksa
Gutpela samting bilong enjiniaring:
Ol dispela samting i save daunim tru hevi bilong'hydrogen embrittlement', moa yet bihain long 'hot dip galvanizing'.
Ol gutpela yus kes:
Ol sistem bilong putim sola
Ol bikpela konstraksen projek
Kost-sensitiv prokiumen
2. 35# & 45# Stil – Strong moa long ol bikpela bolt
Long ol bikpela diamita o bikpela lod rikwaemen, mipela i yusim:
35# Ain
45# Namel Kabon Stil
Proses we ol i bosim:
Precision quenching na tempering
Strongpela kontrol bilong tempereja bilong oven
Risalt:
I winim ful800 MPa strong bilong tanim
Em i save holim strong na i no save bruk bruk
Ol gutpela yus kes:
Ol hevi ain straksa
Ol infrastraksa projek
Bikpela-diamita bilong ol samting bilong pasim
3. 40Cr Alloy Steel – Bilong Ol Hevi na Hai-Stres Envairomen
Taim ol projek i laikim moa long standet pefomens, mipela i save givim40Cr aloi steel apgret.
Ol bikpela gutpela samting:
Hat bilong as bilong en i antap moa
Gutpela strong bilong sakim les
Gutpela wok aninit long 'vibration'
Ol i rekomendim long:
Win pawa straksa
Ol taua bilong trensmisin
Low-temperature envairomen
Teknikel Data bilong ol Bolt Materiel bilong Mipela
| Gret bilong ol samting | Stendet | Kabon Konten | Bikpela samting | Aplikesen we ol i rekomendim |

Hot Dip Galvanising (HDG): I no Kot tasol, Tasol Proteksen
Olgeta bolt i gathot dip galvanising (HDG)long mekim gutpela wok long sakim korosen longpela taim.
Ol ditel bilong proses:
Immersion in molten zinc (>450 digri)
Tiknes bilong koting:60–85μm
Standet: ASTM A153 / ISO 1461
Ol bikpela samting we planti saplaia i no save tingim:
Bihain long 'galvanizing', 'thread tolerance' i senis.
Mipela i katim gen o paitim ol tret bihain long mipela i 'galvanize'
Mekim gutpela fit bilong ol nat
I rausim ol hevi bilong instolesen long -sait
Bilong wanem ol liklik pe "Gred 8.8" bolt i no wok gut
Planti taim, ol saplaia we i no gat bikpela pe:
Yusim ol pipia ain ol i bin yusim gen
Fosim samting long kamap 8.8 long rot bilong hat tritmen
Wanem samting i kamap bihain:
Hat bilong pes i ken lus
Intanal grein straksa i no strong yet
Ol bolt i save bagarap aninit long gutpela lod kondisen
Planti taim dispela i save kamapim:
Hevi bilong straksa
Projek i les
Ol kos bilong lukautim i go antap
As tingting bilong mipela long wokim ol samting
Mipela i bihainim wanpela isipela lo:
Ol samting namba wan, gret namba tu
Vejin ain waia stik tasol
Kontrolim metalurjikel straksa
Sekim wok bilong masin
Dispela i mekim:
Stebol tensil strong
Gutpela longpela
Longpela taim reliabiliti insait long ausait envairomen
Kisim wanpela kwot bihainim ol nid bilong projek bilong yu
Ol narapela narapela projek i nidim ol narapela narapela rot bilong stretim hevi.
Yu ken tokim mipela long wanem samting yu laikim, mipela bai stretim ol samting:
"Mi nidim ol 8.8 HDG bolt we i no gat bikpela pe" →10B21 solusen
"Mi nidim bikpela strong bilong hevi straksa" →45# ain
"Mi nidim bikpela strong long win o guria" →40Cr apgret
Long Handan Dongchao Hardware
Mipela i wanpela profesenel kampani bilong wokim ol samting bilong pasim ol samting na mipela i lukluk long:
Ol sola mounting fasteners
Ol bolt bilong straksa
Ol kastom materiel solusen
Mipela i no save saplaim ol bolt tasol.
Mipela i helpim yu long abrusim feil.
