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

2026-09-21

1. Nhanganyaya kune Flange Bolts uye Anti-Corrosion Zvinodiwa

Flange mabhaudhi zvisungo zvakakosha zvinoshandiswa zvakanyanya mumapombi masisitimu, midziyo yekumanikidza, simbi yekubatanidza, maassemblies emotokari, kuisirwa magetsi emhepo, zvidyarwa zvepetrochemical, uye zvinorema maindasitiri midziyo. Aya mabhaudhi ane hunyanzvi anovimbisa akachengeteka, anovuza-uchapupu majoini pakati pemaflange ari pasi pekumanikidzwa kukuru uye mekiniki mutoro. Nekudaro, munzvimbo chaidzo dzesevhisi dzepasirese dzinosanganisira mwando, munyu wekupfapfaidza, makemikari emumaindasitiri, hunyoro hwepamusoro, kana mhepo yegungwa, mabhaudhi esimbi akajairwa anogona kukurumidza kuita ngura uye ngura. Progressive oxidation inoderedza clamping simba, inokonzeresa kudonha kwemajoini, inonetesa kurongeka kwechimiro, uye inotungamira kune inodhura kutadza nguva isati yakwana.

Kugadzirisa matambudziko aya, indasitiri yemazuva ano inotsamira pamatekinoroji ekudzivirira epamusoro. Pakati pemhinduro dzinoshanda zvikuru Dacromet (inozivikanwawo seDacomet kana zinc-aluminium flake coating). Dacromet-yakavharwa flange mabhaudhi inopa yakanakisa corrosion resistance, zvinoshamisa anti-ngura kushanda, uye kwenguva refu kudzivirira ngura. Ichi chinyorwa chinosuma Dacromet flange mabhaudhi zvakadzama, inovhara kuumbwa, kuita zvakanakira, hunyanzvi hunhu, uye kukosha kwekushandisa mukukumbira. anti-corrosion nharaunda.

2. Chii chinonzi Dacromet Coating?

Dacromet ndeyepamusoro-inoshanda zinc-aluminum flake coating system yakagadziridzwa seimwe nzira yepamberi kune yechinyakare electroplating uye inopisa-dip galvanizing. Iyo yekupfekedza ine matinji anopindirana ezinc uye aruminiyamu flakes akarembera mune inorganic binder. Mushure mekushandiswa ne dip-spin, spray, kana dip-drain nzira uye nepamusoro-tembiricha kurapa, maflakes anoumba dense, multi-layered chipingamupinyi chinopa akawanda maitiro e. anti-corrosion kudzivirira.

Kusiyana neyakajairwa zinc plating inotsamira pane imwechete inoenderera simbi layer, iyo lamellar chimiro che zinc uye aluminium flakes inogadzira nzira yakaoma inononoka kupinza kwemvura, okisijeni, uye chloride ions. Iyi yakasarudzika microstructure inoumba hwaro hwekushongedza kwepamusoro corrosion resistance uye kwenguva refu kudzivirira ngura kugona. Yakajairika Dacromet coating ukobvu kubva pa5 kusvika ku12 micrometers (μm). Pasinei nehuwandu hwayo hutete, Dacromet layer yakashandiswa zvakanaka inogona kuwana munyu wekupfapfaidza kuramba unopfuura maawa 1,000-uye kazhinji pamusoro pemaawa 2,000-pasina chitarisiko chitsvuku. Level iyi ye anti-ngura kuita kunodarika akajairwa emagetsi-galvanized coatings uye anowanzo kukunda kupisa-dip galvanizing mune cyclic uye yenguva refu yekuratidzwa bvunzo.

3. Mabhenefiti Akakosha eDacromet Flange Bolts

Dacromet flange mabhoti anosanganisa kuvimbika kwemuchina nepamusoro anti-corrosion kusimba, zvichiita kuti ive yakakodzera kune yakakwirira-simba uye yakakosha yekusimbisa maapplication.

3.1 Kusaita Corrosion Resistance uye Anti-Rust Performance

Chikonzero chikuru chekusarudza Dacromet-yakavharwa flange mabhoti ndiyo yakasarudzika corrosion resistance. Yakazvimirira munyu yekupfapfaidza bvunzo (ASTM B117 / ISO 9227) inogara ichiratidza kuti Dacromet coatings inomira chiuru kusvika 2,000 maawa kana kupfuura isati yaonekwa ngura tsvuku. Kuenzanisa kuongororwa kunoratidza kuti Dacromet inowanzopa 3 kusvika ku10 nguva dziri nani anti-ngura kushanda kupfuura standard zinc electroplating. Mukuru uyu kudzivirira ngura Kugona kunoshandura hupenyu hwakawedzerwa hwesevhisi yekubatana kweflange kunoratidzwa kune hutsinye hwakadai semahombekombe, mugungwa, uye maindasitiri mamiriro ekunze.

3.2 Hapana Ngozi yeHydrogen Embrittlement

High-simba flange mabhaudhi (magiredhi 8.8, 10.9, 12.9 uye ASTM A490 / F3125 structural bolts) anonyanya kunzwa kune hydrogen embrittlement. Chinyakare electroplating inosanganisira acidic pickling uye electrolytic deposition iyo inogona kupinza haidhirojeni musimbi, zvichikonzera kunonoka kuputsika. Dacromet inzira isiri-electrolytic inodzivirira njodzi iyi, ichiita Dacromet-yakarapwa mabhaudhi inodiwa. anti-corrosion mhinduro ye-high-tensile flange bolts.

3.3 Yakatetepa Coating neYakanakisa Thread Kuenderana

Iine ukomba hwakajairwa hwe5-12 μm chete, iyo Dacromet firimu hainyatso shandura zviyero zveshinda kana kukanganisa kubatanidzwa kwenzungu. Kusiyana neizvi, kupisa-dip galvanizing kunowanzo gadzira machira akakora, asina kuenzana anozadza shinda uye anoda nzungu dzakakura. Dacromet flange mabhaudhi anogona saka kuunganidzwa neakajairika nzungu achiri kuendesa akatanhamara corrosion resistance uye anti-ngura kudzivirira.

3.4 Yakakwirira-Tembiricha Kugadzikana uye Multi-Mechanism Dziviriro

Dacromet coatings inochengetedza yavo anti-corrosion kutendeseka pane tembiricha dzakakwirira (kazhinji dzinosvika 250–300 °C), iyo yakakosha kumabhaudhi eflange padyo neinjini, masisitimu emhepo, kana zvimiro zvekunze. Iyo yekupfekedza inopa ina inopindirana kudzivirira ngura nzira: (1) Kudzivirirwa kwezvipingamupinyi kubva pakuputirana zinc-aluminium flakes; (2) Galvanic chibayiro kudzivirira ne zinc; (3) Kuzvigadzirisa pachako mhedzisiro kuburikidza neoxyde kuzadza kwekukuvadza kudiki; uye (4) Passivation by the inorganic binder inodzoreredza kumwe kuenderera mberi kwekuora.

4. Mashandisirwo Akajairika eDacromet Flange Bolts

Nekuda kwekunaka kwavo anti-corrosion uye anti-ngura zvivakwa, Dacromet flange mabhaudhi anotsanangurwa zvakanyanya mumaindasitiri anoda kuvimbika kwenguva refu pasi pemamiriro ekuora:

Offshore uye zvivakwa zvemahombekombe: Wind turbine tower, mapuratifomu ekumahombekombe, mabhiriji emahombekombe, uye zvivakwa zvechiteshi zvinobatsirwa nepamusoro-munyu-spray. corrosion resistance.
Motokari uye zvekufambisa: Chassis, kumiswa, kupera simba, uye underbody fasteners zvinoda kuvimbika kudzivirira ngurapamusoro pemugwagwa munyu uye hunyoro.
Petrochemical uye makemikari kugadzirisa: Pipeline uye reactor flange zvinongedzo zvinotarisana nekuenderera mberi kwemakemikari kuratidzwa; Dacromet inopa yakasimba anti-corrosion
Kugadzira simba uye kutapurirana: Transmission tower bolts uye magetsi ekugadzira magetsi anovimba neDacromet's anti-ngurakuita munzvimbo dzekunze.
Michina inorema, kurima, uye kuvaka: Zvishandiso zvinoshanda muvhu rakanyorova, mafetireza, kana mhepo yemugungwa zvinoenderana neDacromet's corrosion resistanceuye kwenguva refu kudzivirira ngura.

5. Pfupiso yeBenefits uye Mhedziso

Kusarudza Dacromet-yakavharwa flange mabhoti kunounza akawanda mabhenefiti anoshanda:

Yakavandudzwa zvinoshamisa corrosion resistanceuye anti-ngura kushanda kuchienzaniswa neyakajairwa zinc coatings.
Nguva refu yekugadzirisa uye kuderedzwa kwehupenyu hwehupenyu nekuda kwekuwedzera kudzivirira ngura.
Yakachengeteka application pane yakakwirira-simba mabhaudhi pasina hydrogen embrittlement njodzi.
Kuchengetedzwa kweiyo chaiyo shinda geometry yekusangana yakavimbika uye kushandiswazve.
Kuita kwakanakisa munzvimbo dzakaremerwa nemunyu, hunyoro, makemikari, uye tembiricha.

Mukupedzisa, Dacromet flange mabhaudhi anomiririra yakakura, yepamusoro-inoshanda mhinduro kune mainjiniya nevashandi vekugadzirisa vanoda zvese kuvimbika kwemuchina uye nepamusoro. anti-corrosion kudzivirira. Kuburikidza nemusanganiswa wakasarudzika wekudzivirira kwezvivharo, chibayiro zinc chiito, kuzviporesa maitiro, uye inorganic passivation, Dacromet machira anoburitsa akasarudzika. corrosion resistance, zvinoshamisa anti-ngura kugona, uye kwenguva refu kudzivirira ngura. Ingave ichishandiswa muma turbines emhepo ekumahombekombe, zvivakwa zvemahombekombe, chassis yemotokari, petrochemical plant, kana inorema maindasitiri midziyo, Dacromet-yakavharwa flange mabhoti anogara achipfuura echinyakare epamusoro kurapwa mukusimba uye kuvimbika.

Kune dzakakosha flange yekubatanidza yakafumurwa kune inoora sevhisi mamiriro, kutsanangura Dacromet flange mabhaudhi isarudzo ine hunyanzvi inosimudzira kuchengetedzeka, inoderedza mutengo wehupenyu, uye inova nechokwadi chekusingaperi kwechimiro chechimiro kuburikidza nepamusoro. corrosion resistance uye akavimbika kudzivirira ngura.
