Hāʻawi ka Grade 10.9 Blue-White Zinc DIN 933 hex bolt i ka hiki ke hoʻopili ikaika (ikaika tensile ≥ 1,040 MPa) me ka hoʻopau ʻana i ka hoʻohiwahiwa a me ka hoʻohana pono ʻana o RoHS. ʻO ia ka mea paʻa i koho ʻia no nā hui ʻenekini kaʻa, nā mīkini kaumaha, nā hoʻohui ʻana i ka makani turbine, a me nā mea hana kila kahi e koi ʻia ai nā hui paʻa, kiʻekiʻe-clamping-ikaika.

Papa 10.9 DIN 933 Hex Bolt me Blue-White Zinc Electroplating Finish

Mahele 1 — Papa 10.9: Papa Hoʻopaʻa Kiʻekiʻe

ʻO ka papa 10.9 ka papa waiwai kūlana kiʻekiʻe ʻelua no nā mea hoʻopaʻa metric ma lalo o ISO 898-1, e noho ana ma waena o ka Papa 8.8 i hoʻohana nui ʻia a me ka Grade 12.9 ikaika loa. Hāʻawi ia i kahi kaulike koʻikoʻi o ka ikaika kiʻekiʻe, ʻae ʻia ka ductility, a me ka hana luhi hiki ke wānana, e hoʻolilo iā ia i ka kikoʻī paʻamau no nā ʻāpana bolted koʻikoʻi i nā ʻāpana kaʻa, ikehu, a me nā mīkini kaumaha.

Wehewehe Papa Waiwai

Helu mua (10): Hōʻike i ka 1/100 o ka ikaika tensile haʻahaʻa haʻahaʻa ma MPa → ka ikaika tensile liʻiliʻi = 1,000 MPa (kūpono ma 1,040 MPa).
Helu lua (9): Hōʻike i ka lakio o ka ikaika hua liʻiliʻi i ka ikaika tensile liʻiliʻi × 10 → ratio hua = 0.90, ʻo ia hoʻi ka ikaika hua liʻiliʻi = 940 MPa.

Hana kila: Hoʻopili mua ʻia nā friction-grip (BS EN 14399-3 HR system), nā hui alahaka.

Māhele 2 - DIN 933: Kūlana Kūlana Hexagon Bolt piha

Hōʻike ʻo DIN 933 i nā bolts hexagon-head piha me nā metric coarse pitch thread mai M1.6 a i M52. ʻOiai ua hoʻololi ʻia e ISO 4017, ʻo DIN 933 ka mea i kuhikuhi pinepine ʻia i nā palapala kūʻai ʻEulopa, nā kiʻi ʻenehana, a me nā bila o nā mea i ka honua.

Nā hiʻohiʻona nui kiʻi

ʻO ke kaula piha piha: Hoʻonui ʻia ke kaula i ka lōʻihi holoʻokoʻa, e hoʻonui i ka maʻalahi o ka lōʻihi o ka clamp a me ka hoʻomaʻamaʻa ʻana i ka waihona - hoʻokahi ʻāpana e hoʻololi i nā bolts i hoʻopaʻa ʻia i kekahi hapa.
Poʻo Hexagon: ʻO ka laulā ma waena o nā palahalaha (s) no DIN EN ISO 272. ʻO ke kiʻekiʻe o ke poʻo inoa (k) hāʻawi i kahi kūpono kūpono no nā hui holoi maʻamau a me ka hoʻopili kumu.
Metric koʻikoʻi pitch: No ISO 261/ISO 724. ʻOi aku ka ʻae ʻana o nā kaula koʻikoʻi i ka pōʻino o ka ʻili, ʻoi aku ka liʻiliʻi o ka ʻāʻī ʻana, a ʻoi aku ka wikiwiki o ka hui ʻana ma mua o nā koho maikaʻi.
Papa hoʻomanawanui: Hua huahana A no ka nui ≤ M24 a me ka lōʻihi ≤ 10d a i ʻole ≤ 150 mm; pae huahana B no nā nui nui (ISO 4759-1).

DIN 933 Papa 10.9 Hōʻike wikiwiki

Nā nui DIN 933 maʻamau no ka hana ʻana o ka Papa 10.9 (M6–M24). Ua helu ʻia nā haʻawe uʻi ma ka liʻiliʻi o ke koʻikoʻi ʻāpana × 1,040 MPa.

Hōʻailona hōʻailona

ʻO kēlā me kēia papa 10.9 DIN 933 bolt i hōʻailona ʻia me ka "10.9" a me ka hōʻailona hōʻailona o ka mea hana e like me ke koi ʻia e ISO 898-1. Hāʻawi ka zinc polū-keʻokeʻo i ka ʻike ʻike koke a kōkua i ka hoʻokaʻawale ʻana i ka maikaʻi.

Mahele 3 — Blue-White Zinc Electroplating

ʻO ka zinc polū-keʻokeʻo (Zn/An/Cn/T0 no ISO 2081, a i ʻole Type II SC 1 ma ka ASTM B633) he zinc electroplated coating i hoʻopau ʻia me kahi trivalent chromium (Cr-III) polū-keʻokeʻo hoʻololi. Hoʻohui ia i ka pale corrosion haʻahaʻa, kahi hiʻohiʻona nani nani, a me ke kumu kūʻai haʻahaʻa - e lilo ia i hoʻokahi o nā lāʻau lapaʻau kaulana loa no nā mea hoʻopaʻa ikaika kiʻekiʻe i hoʻohana ʻia i nā kaiapuni semi-pale.

Pehea ka hana ʻana o ka paʻipaʻi Zinc Blue-White

ʻO ke kaʻina hana he ʻekolu mau ʻanuʻu kaʻina:

Electro-hoʻomaʻemaʻe a me ka hana: Hoʻopau ʻia ka ʻili o ka bolt a hoʻohana ʻia i ka waikawa e hōʻoia i ka hoʻopili ʻana o ka zinc.
Zinc electrodeposition: Hoʻokomo electrolytically kahi papa o ka zinc maʻemaʻe (8-12 µm) ma luna o ka substrate kila i loko o kahi ʻauʻau zinc acid a alkaline.
Polū-keʻokeʻo passivation: Hoʻokomo ʻia ka bolt hou i hoʻopaʻa ʻia i loko o kahi hopena passivation trivalent chromium (Cr-III), e hana ana i kahi kiʻi ʻoniʻoni ʻoniʻoni ʻoniʻoni a i ʻulaʻula e hoʻopaʻa ai i ka zinc a hāʻawi i ke ʻano keʻokeʻo uliuli keʻokeʻo.
ʻO ka paila ʻana i ka hydrogen de-embrittlement: Hoʻomoʻa ʻia nā bolts papa 10.9 ma 190–220 °C no 4-8 mau hola i loko o 4 mau hola o ka hoʻopaʻa ʻana (ISO 9588) e hoʻokuke aku i ka hydrogen diffusible a pale i ka haki ʻana i ka lohi.

Ka pale ʻana i ka paʻakai no ka ISO 9227 neutral salt spray (NSS). ʻO ka ʻōpala keʻokeʻo = zinc corrosion products; ʻeleʻele ʻulaʻula = ʻānai ʻana o ke kumu kila. Pono ka hydrogen de-embrittlement no nā mea paʻa me ka paʻakikī ≥ 320 HV no ISO 4042.

Pōmaikaʻi no ka Papa 10.9 noi

ʻO ka hōʻoia ʻana o ka maikaʻi ʻike: Hiki ke ʻike koke ʻia nā hemahema o ka ʻili ( nā ʻōpala, nā wahi i hoʻopaʻa ʻole ʻia, ka lepo) i ka wā o ka nānā ʻana.
Pili ka pae: Ma ka 8-12 µm, ua lahilahi ka uhi no ka mālama ʻana i nā aho maʻamau (6g/6h) me ka ʻole o ka paʻi hou ʻana - koʻikoʻi no nā hui bolted ikaika kiʻekiʻe.
ʻO ke kuʻi ʻana: Hāʻawi ka ʻili i hoʻopaʻa ʻia i kahi koena friction kūlike (µ ≈ 0.12–0.20), e kākoʻo ana i nā helu preload e pili ana i ka torque.
Kumukuai: ʻO ka Zinc electroplating ka mea ʻoi aku ka maikaʻi o ka pale ʻana i ka corrosion no nā mea hoʻopaʻa, me ka haʻahaʻa haʻahaʻa haʻahaʻa ma mua o Dacromet a i ʻole hot-dip galvanising.
Kūlike kaiapuni: Hoʻokō ka passivation Trivalent (Cr-III) i nā koi RoHS a me REACH; ʻaʻole like me nā kaʻina hana hexavalent chromium (Cr-VI) kahiko, ʻaʻohe pilikia o ke olakino a i ʻole nā hana.

Nā palena a me nā hana maikaʻi loa

Hoʻolālā ʻia ka hoʻoheheʻe zinc polū-keʻokeʻo no nā kaiapuni waho o loko a me ka semi-protected (corrosivity categories C1-C2 no ISO 12944). No ka hōʻike pololei ʻana i waho, nā kaiapuni kahakai (C3+), a i ʻole nā noi e koi ana i ka ≥ 480 h ka pale ʻana i ka paʻakai paʻakai, e noʻonoʻo iā Dacromet a i ʻole ka galvanising wela. E hōʻike mau i ka bake hydrogen de-embrittlement ma nā kauoha kūʻai no nā mea hoʻopaʻa zinc-plated Grade 10.9.

E pili ana i Fujirui Metal — Mea Hana Hoʻopaʻa Paʻa ʻOihana & Mea Hoʻopuka

Hana a hoʻokuʻu aku ʻo Fujirui Metal i nā mea hoʻopaʻa pololei me ka Grade 8.8 / 10.9 / 12.9 hex bolts, DIN 933 bolts full-thread, DIN 931 partial-thread bolts, stud bolts, a me nā mea hoʻopaʻa maʻamau. ʻO nā koho lapaʻau ʻili he zinc polū-keʻokeʻo, zinc melemele, Dacromet, Ruspert, hot-dip galvanising, a me ka mīkini zinc plating. Hana ʻia nā huahana a pau i nā kūlana ISO, DIN, a me ASTM me nā palapala hōʻike hōʻike piha piha (MTC) i loaʻa.
