Dacromet Flange Bolts: Sumo Yakakwana kune Yepamusoro-Kuita Anti-Corrosion Fasteners.

2026-10-16

1. Nhanganyaya kuDacromet Flange Bolts

Mumaindasitiri emazuva ano mashandisirwo, kuvimbika kwemasisitimu ekutsanya kwakakosha. Pakati pezvigadziriso zvepamberi zviripo nhasi ndezvi Dacromet flange mabhoti. Aya mabhaudhi ane hunyanzvi anosanganisa mabhenefiti emakanika dhizaini yeflange neakasarudzika anti-corrosion uye anti-ngura zvivakwa zveDacromet coating tekinoroji.

A flange bolt inoratidzira yakabatanidzwa washer-yakafanana flange pasi pemusoro. Iyi dhizaini inogovera iyo clamping mutoro pamusoro penzvimbo yakakura, inoderedza njodzi yekukuvadzwa kwepamusoro, uye kazhinji inobvisa kudiwa kwewasher yakasiyana. Kana iyi flange bolt inobatwa nayo Dacromet - isiri-electrolytic zinc-aluminum flake coating - inova yemhando yepamusoro yekusimbisa inokwanisa kushingirira nharaunda dzinoparadza kwenguva yakareba.

Dacromet coating, inozivikanwawo se zinc flake coating, inopa yakanakisa dziviriro kubva kune ngura uye ngura. Iyo inotsanangurwa zvakanyanya kune yakakwirira-simba mabhaudhi (Giredhi 8.8, 10.9, uye 12.9) anoshandiswa mumotokari, kuvaka, mugungwa, simba remhepo, uye maindasitiri emuchina mashandisirwo uko yechinyakare zinc plating kana inopisa-dip galvanizing inogona kudonha.

2. Chii chinonzi Dacromet Coating?

Dacromet is anorganic, water-based coating system inoumbwa zvakanyanya ne zinc nealuminium flakes yakaturikwa mu chromium-ine binder. Iyo yekupfekedza inoiswa ne dip-spin, spray, kana dip-drain nzira uye yobva yapora patembiricha yakakwira (kazhinji 300-320 ° C). Iyi nzira inoumba mutete, dense, multi-layered chipingamupinyi (kazhinji 4-8 μm gobvu) inosungira kemikari nesimbi substrate yebhaudhi.

Kusiyana neyakajairwa electroplating, iyo Dacromet process haisanganisire asidhi pickling kana electrolysis. Naizvozvo, inosuma hapana hydrogen embrittlement njodzi - mukana wakasarudzika weakakwira-tensile mabhaudhi ayo anofanirwa kuchengetedza kutendeseka kwechimiro pasi peyakakwira preload uye cyclic kurodha.

Hunhu Hunokosha hweDacromet Coating paBolts

Superior corrosion resistance: Kazhinji inodarika 1,000 maawa ekusarerekera munyu kupfapfaidza kuyedzwa (ASTM B117 / ISO 9227) isina ngura tsvuku.
Firimu yakaonda uye yakafanana: Chete 4-8 μm gobvu, kuchengetedza chaiyo tambo kushivirira kwebhaudhi.
High tembiricha kuramba: Inochengetedza kushanda kwekudzivirira kusvika ku300 ° C inoenderera sevhisi.
Yakanakisa makemikari kuramba: Inopikisa munyu wemumugwagwa, zvinwiwa zvemotokari, maasidhi akapfava, uye mamiriro ekunze emaindasitiri.
Controlled friction: Inopindirana torque-tension hukama hwekusimbisa bhaudhi yakavimbika.
Silver-grey metallic kutaridzika: Uniform, matte kupera iyo zvakare inopendwa.

3. Zvakanakira zveDacromet Flange Bolts

Dacromet flange mabhoti inopa yakasarudzika musanganiswa wemakanika uye pamusoro-yekudzivirira mabhenefiti anoita kuti vafarirwe pane akajairwa akavharidzirwa mabhaudhi munzvimbo dzinoda.

Exceptional Anti-Corrosion uye Anti-Rust Performance

Iyo yakawanda-yakaiswa zinc-aluminium flake chimiro cheDacromet inogadzira zvese zvipingamupinyi mhedzisiro uye chibayiro anode mhedzisiro. Iyi nzira mbiri inopa 7 kusvika ku10 nguva kupikisa kwekuora kwechinyakare electro-galvanized coatings. High-quality Dacromet flange bolts inogona kuwana maawa anopfuura 1,200 emunyu wekupfapfaidza kuramba pasina kuonekwa kwehutu dzvuku, kuve nechokwadi chekudzivirira kwenguva refu-anti-rust kunyange mumhenderekedzo yegungwa, yegungwa, kana kuti ine munyu wakawanda.

Hapana Hydrogen Embrittlement Ngozi

High-simba mabhaudhi (kunyanya Giredhi 10.9 uye 12.9) zvakanyanya kubatwa nehydrogen embrittlement kana ichigadziriswa neyakajairwa electroplating. Iyo Dacromet process inobvisa acid pickling uye electrolytic deposition, kudzivirira zvachose sumo yehydrogen. Izvi zvinogadzira Dacromet iyo yakasarudzika yejasi yeakakomba masisitimu uye ane hukama-ane hukama flange mabhaudhi.

Yakatetepa Coating Inochengetedza Thread Fit

Iine ukomba hwakajairwa hwe4-8 μm chete, Dacromet coating haishandure zvakanyanya dhayamita yesimbi yebhaudhi. Izvi zvinobvumira kushandiswa kwenzungu dzemazuva ose pasina kudiwa kwe overtapping, iyo inowanzodiwa kune yakakora inopisa-dip galvanized coatings. Mhedzisiro iri nani yekubatana kweshinda, kuwedzeredza kurodha, uye nyore kuungana kwemabhaudhi eflange.

4. Kuita Kuenzanisa kweBolt Coatings

Tafura inotevera inofananidza Dacromet neyakajairwa mamwe machira anoshandiswa pamabhoti:

Property	Dacromet	Electro-Zinc Plating	Hot-Dip Galvanizing
Coating Ukobvu	4–8 μm	5–15 μm	40–80 μm
Salt Spray Resistance (kune red rust)	≥ 1,000–1,200 h	100–300 h	500–800 h
Hydrogen Embrittlement Ngozi	Hapana	Yakakwirira (inoda kubika)	Pakati
High-Temperature Resistance	Kusvikira ku300°C	≤ 120°C	≤200°C
Thread Fit Kuenderana	Yakanakisa (yakajairwa nzungu)	Zvakanaka	Inoda overtapping
Kukodzera kune High-Simba Bolts	Yakanaka (10.9 / 12.9)	Limited	Pakati nepakati

5. Kusarudza Nhungamiro yeDacromet Flange Bolts

Paunenge uchitsanangura ma Dacromet flange mabhaudhi epurojekiti, funga zvinotevera zvinhu kuti uve nechokwadi chekuita kweanti-corrosion kuita uye kuvimbika kwakabatana:

1.Corrosivity yezvakatipoteredza: Mhenderekedzo yegungwa, yegungwa, maindasitiri, kana mugwagwa-munyu kuratidzwa kazhinji kunoruramisa Giredhi B kana yepamusoro maDacromet machira.

2.Bolt simba giredhi: Kune Giredhi 10.9 uye 12.9 flange mabhaudhi, Dacromet inokurudzirwa zvakasimba kubvisa hydrogen embrittlement njodzi.

3.Temperature exposure: Zvikumbiro zvinosvika 250-300 ° C zvinobatsira kubva kuDacromet's thermal stability.

4.Torque-tension zvinodiwa: Rondedzera jasi repamusoro rakazorwa (semuenzaniso, PLUS® kana DACROLUB®) apo chaiyo preload control yakakosha.

5.Kuenderana nezvikamu zvekusangana: Dacromet inoratidza yakanaka bimetallic kuwirirana nealuminium zvikamu, kuderedza galvanic corrosion ngozi.

6. Mhedziso

Dacromet flange bolts inomiririra yakakura, yakakwirira-yekuita yekusimbisa mhinduro iyo panguva imwe chete inogadzirisa mechanical joint kutendeseka uye yenguva refu yekudzivirira kwepamusoro. Nekubatanidza iyo mitoro-kugovera zvakanakira yemusoro weflange neyakatanhamara anti-corrosion uye anti-ngura zvivakwa zve zinc-aluminium flake coating, mabhaudhi aya anoburitsa sevhisi yakavimbika munzvimbo dzine hutsinye.

Zvinotora zvakakosha zvemainjiniya uye nyanzvi dzekutenga zvinhu zvinosanganisira:

Dacromet inopa 7-10 nguva yekuramba kwecorrosion kweyakajairwa electro-zinc plating ichisara yakatetepa zvakakwana kuchengetedza yakajairwa shinda inokwana.
Iyo isiri-electrolytic process inobvisa zvachose hydrogen embrittlement, ichiita kuti ive yakanaka kune yakakwirira-simba flange mabhaudhi.
Yakanakisa yepamusoro-tembiricha kugadzikana (kusvika 300 ° C) uye makemikari kuramba anowedzera kuwedzera mikana yekushandisa.
Iyo yakabatanidzwa flange dhizaini inorerutsa kuungana uye inovandudza kuita kwakabatana pasi pe vibration uye cyclic kurodha.

Ingave ichishandiswa mumotokari chassis, offshore wind turbines, coastal infrastructure, kana inorema maindasitiri emidziyo, Dacromet flange bolts inopa nzira yakapupurirwa yehupenyu hurefu hwebasa, kuderedzwa kugadzirisa, uye kuchengetedzwa kwakawedzerwa. Kutsanangura iyo chaiyo Dacromet giredhi uye kuve nechokwadi chekutonga kwakaringana kunowedzera iyo anti-ngura uye anti-corrosion mabhenefiti ayo mabhaudhi epamberi akagadzirirwa kuendesa.
