Dacromet Hex Bolts Inotungamira Inotevera Wave yeAnti-Corrosion Kutsanya 

Kusiyana neyakajairwa electroplated zinc, iyo Dacromet process inosuma kwete haidrojeni mu substrate. Izvi zvinobvisa njodzi yehydrogen embrittlement-yakakosha mukana kana uchivhara yakakwirira-simba hex mabhaudhi emagiredhi 8.8, 10.9, uye 12.9. Mhedzisiro ndeye Ngura-inodzivirira hex bolt iyo inochengeta kuperera kwemechanical uku ichipa corrosion resistance yakakwira zvakanyanya kune yakajairwa kupera.

Nei Hex Bolts Inobatsira Yakawanda kubva kuDacromet

Hex mabhaudhi-kunyanya mabhaudhi anorema ehekisi-anotsanangurwa zvakanyanya mumabhiriji, shongwe dzesimba remhepo, muchina unorema, uye chassis yemotokari. Aya maapplication anoda mafasteners anosanganisa chaiyo torque-tension maitiro nemakumi emakore-akareba anti-corrosion hupenyu. Dacromet inosangana nezvose zvinodiwa:

• Uniform coveragepashinda yakaoma geometry pasina kuvaka-up kwakabatana nekupisa-dip galvanizing, kuchengetedza dimensional kurongeka uye shinda yakakodzera.
• Inodzorwa coefficient ye friction(kazhinji μ = 0.12-0.18 netopcoat), zvichiita kuti zvigadziriswe zvigadziriswe uye kuomesa kwakawanda.
• Hapana hydrogen embrittlement njodzi, zvichiita kuti Dacromet ive yakasarudzwa anti-ngurakupedzisa kweakakwira-tensile hex mabhaudhi anoshandiswa mukuchengetedza-akakosha majoini.
• Tembiricha kuramba kusvika 300°C, inopfuura kure miganhu inoshanda ye electroplated zinc.

Corrosion Performance: Dacromet vs. Traditional Coatings

Kuongororwa kwakazvimirira kwerabhoritari kunoratidza nguva dzose izvozvo Dacromet-yakavharwa hex mabhaudhi Kupfuura zvese zviri zviviri electroplated zinc uye inopisa-dip galvanized fasteners mune zvakarerekera munyu-spray (ASTM B117 / ISO 9227) uye cyclic corrosion bvunzo. Kuenzanisa kunotevera kunopfupisa zvakajairika mhedzisiro yeakaenzana coating masisitimu:

Tafura 1. Kuenzanisa kwekuita kwema-anti-corrosion coatings ehex bolts (yakajairika laboratory values).

Mune imwe yakanyatso kutaurwa yekukodzera kudzidza yeASTM A490 yakakwirira-simba mabhaudhi ezvimiro, Dacromet-yakavharwa zvikamu zvakaratidza. zero tsvuku ngura mushure memaawa e1,000 ekuenderera mberi kwemunyu-spray kuratidzwa, nepo mabhaudhi ane galvanized airatidza kupfuura 85% ngura yakatsvuka panzvimbo dzakakosha. Kunyangwe mushure memaawa 5,000, zvienzaniso zveDacromet zvakaratidza chete 6% tsvuku tsvuku-zvinoshamisa kudarika inopisa-dip galvanized counterparts iyo yakasvika pedyo-yakazara pamusoro pekuora.

Iyo Sainzi Kuseri Kwepamusoro Anti-Rust Dziviriro

Iyo yakasarudzika anti-corrosion kuita kweDacromet kunobva kune matatu anowirirana nzira:

1. Barrier protection-Kuputira zinc uye aluminium flakes inoumba dense, yakawanda-layer nhovo inotadzisa hunyoro uye chloride ion kupinda.
2. Kudzivirira (cathodic) kudzivirira- Zinc flakes inonyanya kuodza, kuchengetedza simbi yepasi kunyangwe iyo yekuputira yakakuvadzwa munharaunda.
3. Passivation / self-healing- Chromium-oxyde compounds mukati mebinder inogadzira firimu rakagadzikana rinowedzera kunonoka kufambira mberi kwekuora.

Market Outlook uye Indasitiri Zvinoreva

Sezvo kudyara kwezvivakwa zvepasirese kunowedzera uye mapuratifomu emotokari anotama akananga kumatare epamusoro-simba, kudiwa kweakavimbika. anti-corrosion uye ngura-proof fastener solutions inoramba ichikwira. Vacherechedzi veindasitiri vanocherekedza akati wandei anosimbisa maitiro:

• Specification kukura- Zvimwe zviyero zveinjiniya (kusanganisira zvigadziriso zvine chekuita neASTM F3125 zvimiro zvemabhaudhi) zvino ziva zvakajeka zinc-flake masisitimu akadai seDacromet sedzimwe nzira dzinogamuchirwa kune dzechinyakare galvanizing kune yakakwirira-simba maapplication.
• Sustainability kufunga-Mvura-based Dacromet maitiro anogadzira tsvina ine ngozi shoma pane yakawanda electroplating mitsara, inopindirana nekusimbisa mitemo yezvakatipoteredza.
• Mari yese yekuva muridzi-Kunyangwe mutengo weyuniti ungave wakakwira kupfuura yekutanga zinc plating, hupenyu hwesevhisi hwakawedzerwa uye kuderedzwa kwekugadzirisa Dacromet hex bolts kazhinji kuendesa mutengo wakaderera wehupenyu munzvimbo dzinoora.

Nhungamiro Inoshanda kune Vanonyatsotsanangura

Pakusarudza Dacromet-yakavharwa hex mabhaudhi, mainjiniya anofanirwa kuona giredhi rekupotera (semuenzaniso, Giredhi A kana B zvichienderana nehuremu hwekuputira), simbisa kuenderana kwechero mafuta etopcoat ane hukama hwetorque-tension, uye ive nechokwadi chekuti ese mabhaudhi nenzungu dzinoenderana / washer zvinogashira magumo anoenderana. Kuchengetedza kwakakodzera uye kubata kunoramba kuchikosha: nepo kupfekedza kwakanyanya anti-ngura, kukuvara kwemagetsi kusati kwaiswa kunogona kuderedza kuchengetedzwa munharaunda.

Mhedziso

Dacromet tekinoroji yakakura kubva kune yakasarudzika mota kupedzisa kuita mainstream anti-corrosion mhinduro yekushanda kwepamusoro hex mabhaudhi. Mubatanidzwa wayo wakasarudzika wekutetepa-firimu kufanana, kusavapo kwehydrogen embrittlement, yakakwira tembiricha kugona, uye yakaratidza zviuru-zvuru-yawa-yawa-mwaya-munyu-spray kuramba inoisa iyo sechisarudzo chinotungamira chero kupi kwenguva refu. ngura-proof kuvimbika hakutauriki.

Sevaridzi vezvivakwa, vanogadzira mhepo-purazi, uye mota dzeOEM dzinoramba dzichiisa pamberi pekugara uye kuderedzwa kugadzirisa, Dacromet hex bolts vanotarisirwa kutora chikamu chinowedzera chemusika wepamusoro-fastener-kuunza iyo anti-ngura kushanda kunodiwa neinjiniya yemazuva ano.
