2026-07-10

IBanga le-10.9 le-Blue-White Zinc DIN 933 hex bolt linikezela amandla okubamba amandla aphezulu (amandla aqinile ≥ 1,040 MPa) kunye nexabiso elisebenzayo, i-RoHS-ehambelanayo ne-decorative-and-functional surface finish. Sesona siqhoboshiso esisikhethwayo sokudityaniswa kweenjini zeemoto, oomatshini abanzima, uqhagamshelo lweinjini yomoya, kunye nomsebenzi wentsimbi owenziweyo apho kufuneka khona okudityanisiweyo, okudityanisiweyo okuphezulu.

IBakala 10.9 DIN 933 Hex Bolt eneBlue-White Zinc Electroplating Finish

Icandelo 1 - iBanga le-10.9: Iklasi ye-Fastener yamandla aphezulu

IBakala 10.9 lolona didi lwepropathi elukumgangatho ophezulu wesibini kwiziqinisekiso zemetriki phantsi kwe-ISO 898-1, ehleli phakathi kweBanga lesi-8.8 elisetyenziswa kakhulu kunye neBanga le-12.9 elinomgangatho ophezulu kakhulu. Inika ibhalansi enyanzelisayo yamandla aphezulu, i-ductility eyamkelekileyo, kunye nokusebenza okuqikelelwayo kokudinwa, oko kuyenza ibe yinkcazo engagqibekanga kumalungu abalulekileyo adityanisiweyo kumacandelo eemoto, amandla, kunye noomatshini abanzima.

iPropati Class Decoding

Inombolo yokuqala (10): Ibonisa i-1/100 yowona mandla asezantsi etensile kwiMPa → amandla okuqina asezantsi = 1,000 MPa (esemgangathweni we-1,040 MPa).
Umvo wesibini (9): Ibonisa umlinganiselo wobuncinane bamandla esivuno ukuya kumandla obunzima obuncinane × 10 → umlinganiselo wesivuno = 0.90, okuthetha ukuba ubuncinane bamandla esivuno = 940 MPa.

Iifasteners zeBanga le-10.9 zenziwa kwiintsimbi ze-alloy - ngokuqhelekileyo i-40Cr, i-35CrMo, i-42CrMo, okanye i-SCM435 - ejongene nokucima kunye nokushisa (Q&T) unyango lobushushu. Ikhabhoni ephezulu kunye ne-alloy content (Cr, Mo) ibonelela ngobunzima obuyimfuneko ukufezekisa ubunzima obungundoqo obufunekayo be-32-39 HRC kulo lonke i-cross-section, nakwii-diameters ezinkulu (ukuya kwi-M36).

Imiba engundoqo yeSicelo

Iimoto: Iibholithi zokuxhoma i-injini, iibholithi zokudibanisa intonga, iziqhoboshi ze-flywheel, iibholiti zengalo ezixhonyiweyo, ikhonkco lokuqhuba.
Amandla omoya: I-Tower section flanges, i-nacelle structural connections, i-pitch bearing bolts.
Oomatshini abanzima: Iibholiti zomkhondo we-excavator, uqhagamshelo lwesakhelo se-bulldozer, i-crane yabulala izibophelelo zeringi.
Ulwakhiwo lwentsimbi: Ukulayishwa kwangaphambili kwe-friction-grip connections (i-BS EN 14399-3 inkqubo ye-HR), iindibano ezithwele ibhulorho.

Icandelo 2 - I-DIN 933: Imigangatho yeBolt ye-Hexagon egcweleyo

I-DIN 933 ixela iibholithi zehexagon-entloko ezithungelwe ngokupheleleyo ezinemisonto erhabaxa ye-metric ukusuka ku-M1.6 ukuya ku-M52. Nangona ithathelwe indawo ngokobuchwepheshe yi-ISO 4017, i-DIN 933 iseyeyona migangatho yebholt esoloko isalathiswa kumaxwebhu okuthengwa kwempahla aseYurophu, imizobo yobugcisa, kunye neebhili zemathiriyeli kwihlabathi liphela.

Iimpawu eziphambili zoMda

I-shank enemisonto epheleleyo: Umsonto unabela kubo bonke ubude, ukwandisa ubude be-clamp bhetyebhetye kunye nokwenza lula uluhlu lwe-inventri - enye inxalenye ithatha indawo yeebholiti ezininzi zokubambelela-ubude obukhethekileyo obufakwe ngokungagqibelelanga.
Hexagon intloko: Ububanzi kwiiflethi (s) ngokwe-DIN EN ISO 272. Ubude bentloko eqhelekileyo (k) bubonelela ngommandla owaneleyo wokuqulatha iindibano zewasha eziqhelekileyo kunye nokudibana kwesokethi.
I-Metric coarse pitch: Ngokwe-ISO 261/ISO 724. Imisonto erhabaxa iyakwazi ukunyamezela ukonakaliswa komphezulu, ayithandeki kakhulu kwigalling, kwaye iyakhawuleza ukudityaniswa kuneendlela ezizezinye.
Ibakala lokunyamezela: Ibanga lemveliso A ngobukhulu ≤ M24 kunye nobude ≤ 10d okanye ≤ 150 mm; imveliso ibakala B ngobukhulu ezinkulu (ISO 4759-1).

s = ububanzi begama kwiiflethi, k = ukuphakama kwentloko. Umthwalo we-tensile kwi-ISO 898-1 indawo yoxinzelelo × 1,040 MPa.

Ukuchongwa kokuMakisha

Ibholithi nganye yeBakala 10.9 ye-DIN 933 iphawulwe ngentloko ngo-“10.9” kunye nesimboli yokuzazisa yomenzi njengoko kufunwa yi-ISO 898-1. Ukugqitywa kwe-zinc eluhlaza okwesibhakabhaka kunika ukuchongwa okubonakalayo ngokukhawuleza kwaye kunceda ngokuhlelwa kokulawula umgangatho.

Icandelo 3 - I-Blue-White Zinc Electroplating

I-zinc eluhlaza okwesibhakabhaka (i-Zn / An / Cn / T0 nge-ISO 2081, okanye Uhlobo lwe-II SC 1 nge-ASTM B633) yi-zinc electroplated coating egqitywe nge-trivalent chromium (Cr-III) yokuguqulwa kwe-blue-white. Idibanisa ukukhuselwa kwe-corrosion ephakathi, inkangeleko ekhangayo eqaqambileyo yokuhombisa, kunye neendleko eziphantsi-iyenza ibe yenye yezona zonyango zithandwa kakhulu kwindawo yokubopha amandla aphezulu asetyenziswa kwiindawo ezikhuselweyo.

Isebenza njani i-Blue-White Zinc Plating

Inkqubo ibandakanya amanyathelo amathathu alandelelanayo:

Ukucoca i-Electro kunye nokuvula: Umphezulu we-bolt uhlanjululwe kwaye u-acid-activated ukuqinisekisa ukunamathela kwe-zinc efanayo.
I-Zinc electrodeposition: Umaleko we-zinc esulungekileyo (8–12 µm) ifakwe ngokwe-electrolytically kwi-substrate yentsimbi kwibhafu ye-asidi okanye ye-alkaline yezinki.
Intshukumo eblue-white: Ibholithi esandul' ukubethelwa intywiliselwa kwi-trivalent chromium (Cr-III) isisombululo se-passivation, senza ifilim ecekethekileyo ye-transparent-transparent-to-blue etywina i-zinc kwaye ibonelela ngembonakalo eqaqambileyo eluhlaza okwesibhakabhaka-mhlophe.
I-hydrogen de-embrittlement bake: Iibholiti zeBanga le-10.9 zibhakwa kwi-190-220 °C kwiiyure ze-4-8 kwiiyure ze-4 zokucwenga (ISO 9588) ukukhupha i-hydrogen edibeneyo kunye nokuthintela ukulibaziseka kwe-brittle fracture.

Ukumelana nesitshizi setyuwa ngokwe-ISO 9227 ngokungathathi hlangothi kwesitshizi setyuwa (NSS). Umhlwa omhlophe = iimveliso ze-zinc corrosion; umhlwa obomvu = intsimbi ye-substrate corrosion. I-Hydrogen de-embrittlement inyanzelekile kwizibophelelo ezinobunzima ≥ 320 HV nge-ISO 4042 nganye.

Izinto eziluncedo kwizicelo zeBakala 10.9

Ukuqinisekiswa komgangatho obonakalayo: Umbala oqaqambileyo, omhlophe omhlophe ohlaza okwesibhakabhaka wenza iziphene zomhlaba (imikrwelo, iindawo ezingaxutywanga, ukungcola) zibonakale ngokukhawuleza ngexesha lokuhlolwa.
Ukuhambelana kwemisonto: Kwi-8-12 µm, i-coating incinci ngokwaneleyo ukugcina ukunyamezela kwentambo eqhelekileyo (6g / 6h) ngaphandle kokuphinda ucofe - okubalulekileyo kwi-bolted bolted joints.
Ukukhuhlana okulawulwayo: Umphezulu we-as-plated ubonelela nge-coefficient ye-friction engaguqukiyo (µ ≈ 0.12–0.20), exhasa ukubala kwangaphambili okuthembekileyo okusekwe kwitorque.
Ngexabiso: I-Zinc electroplating yeyona ndlela yoqoqosho yokukhusela i-corrosion ye-fasteners, enexabiso eliphantsi kakhulu lokucwangcisa kune-Dacromet okanye i-hot-dip galvanising.
Ukuthobela indalo esingqongileyo: I-Trivalent (Cr-III) passivation ihlangabezana neemfuno ze-RoHS kunye ne-REACH; ngokungafaniyo neenkqubo zechromium enehexavalent endala (Cr-VI), ayibangeli ngozi kwimpilo yomsebenzi.

Unyino kunye neZenzo ezilungileyo

Ukufakwa kwe-zinc eluhlaza okwesibhakabhaka kujoliswe kwindawo yangaphandle kunye ne-semi-protected ngaphandle (iindidi ze-corrosivity C1-C2 ngokwe-ISO 12944). Ukukhutshwa ngokuthe ngqo kwangaphandle, iindawo ezinxweme (C3 +), okanye izicelo ezifuna i-≥ 480 h ukumelana nokutshiza ityuwa, qwalasela i-Dacromet okanye i-hot-dip galvanising. Hlala ucacisa i-hydrogen de-embrittlement bake kwii-odolo zokuthenga zeBanga le-10.9 le-zinc-plated fasteners.

Malunga neFujirui Metal — uMenzi weFastener oyiNgcali kunye noMthumeli ngaphandle

I-Fujirui Metal yenza kwaye ithumele kumazwe angaphandle iziqhoboshi ezichanekileyo ezibandakanya iBanga lesi-8.8 / 10.9 / 12.9 iibholiti zeheksi, iibholithi ze-DIN 933 zomsonto ogcweleyo, iibholithi ze-DIN 931 ezingagqibelelanga, iibholiti ze-stud, kunye nezibophelelo zesiko. Iinketho zonyango ezingaphezulu ziquka i-zinc eluhlaza okwesibhakabhaka, i-zinc emthubi, i-Dacromet, i-Ruspert, i-hot-dip galvanising, kunye ne-mechanical zinc plating. Zonke iimveliso zenziwe ngokwemigangatho ye-ISO, DIN, kunye ne-ASTM ezinezatifikethi zovavanyo olupheleleyo (MTC) ezikhoyo.
