Dacromet Hexagonal Bolts- Advanced Anti-Corrosion & Anti-Rust Fastening Solutions 

2. Kodi Dacromet Coating ndi chiyani?

Dacromet ndi makina opangira zinc-aluminium flake opangidwa ngati njira yotsogola yopangira ma electroplating wamba. Chophimbacho chimakhala ndi zinc flakes ndi ma aluminium flakes mu inorganic binder. Ikagwiritsidwa ntchito pazitsulo za hexagonal ndikuchiritsidwa pafupifupi 300 ° C, imapanga chotchinga cholimba, chamitundu yambiri chomwe chimapereka bwino kwambiri. odana ndi dzimbiri ndi anti-corrosion ntchito.

Makhalidwe ofunikira a zokutira za Dacromet pa mabawuti:

• Filimu yowonda: Nthawi zambiri 4-12 μm (nthawi zambiri 6-8 μm), kusunga ulusi wa geometry ndi kukwanira pamaboti olondola a hexagonal.
• Chotchinga + chitetezo cha nsembe: Zinc zonyezimira ndi ma aluminium flakes amatchinga chinyezi / okosijeni ndikupereka chitetezo cha galvanic (chopereka nsembe) cha gawo lapansi lachitsulo.
• Kufalikira kwa Uniform: Dip-spin kapena spray application imatsimikizira kuphimba bwino kwa ma geometries ovuta, kuphatikiza ulusi wakuya ndi mutu wa hexagonal.
• Maonekedwe: Uniform metallic silver-gray matte kumaliza, yoyenera kugwiritsidwa ntchito komanso kukongoletsa.

3. Ubwino waukulu wa Dacromet Hexagonal Bolts

Kukaniza Kwapadera kwa Corrosion & Anti-Rust Performance

Ubwino waukulu wa Dacromet-wokutidwa ndi hexagonal mabawuti ndiwopambana kukana dzimbiri ndi nthawi yaitali odana ndi dzimbiri kuthekera. Ngakhale zokutira zopyapyala za 4-8 μm zokha, mabawuti awa nthawi zonse amapirira kuyezetsa kwa kupopera mchere wosalowerera ndale (ASTM B117 / ISO 9227) kwa maola opitilira 1,000 — ndipo nthawi zambiri 1,200 mpaka maola 2,000 — popanda dzimbiri lofiira. Izi ndizabwinoko kuwirikiza ka 7-10 kuposa kutulutsa malata wamba (maola 100-300) komanso kupikisana ndi zida zambiri zokhuthala zovimbidwa ndi malata.

Mapangidwe amitundu yambiri ya zinc-aluminium flake amatchinga chinyezi, mpweya, ndi ma chloride. Ngakhale zitawonongeka kwanuko, nsembe ya zinc ikupitilizabe kuteteza gawo la bawuti, kukulitsa zonse. kupewa dzimbiri. Izi zimapangitsa Dacromet hexagonal bolts kukhala yabwino kwa m'mphepete mwa nyanja, m'madzi, m'magalimoto apansi panthaka, komanso malo ogulitsa.

Zero Hydrogen Embrittlement Ngozi

Ubwino wofunikira wamaboti amphamvu kwambiri a hexagonal ndikusowa kwathunthu kwa chiwopsezo cha hydrogen embrittlement. Electroplating imabweretsa atomiki wa haidrojeni muzitsulo, zomwe zingayambitse kusweka kwa brittle m'kalasi 10.9, 12.9, ndi ma bolts monga ASTM A490. Dacromet si electrolytic ndipo imapewa kunyamula asidi mwaukali, kotero palibe haidrojeni yomwe imayambitsidwa. Dacromet yamphamvu kwambiri mabawuti Chifukwa chake musafune kuphika pambuyo pa kuwotcha ndikupereka kudalirika kwakukulu pamalumikizidwe ofunikira kwambiri. Ma OEM ambiri amagalimoto amatchula Dacromet kapena zokutira zofananira za zinc pazifukwa izi.

Kulimbana ndi Kutentha Kwambiri

Zovala za Dacromet zimasunga umphumphu komanso anti-corrosion ntchito pa kutentha kosalekeza mpaka 300 ° C. Electroplating wamba ya zinki imatsika pamwamba pa 100-120 ° C, pomwe kuthirira kotentha kwa dip kumakhala ndi malire apamwamba. Kukhazikika kwamafutawa kumagwirizana ndi ma Dacromet hexagonal bolts a zigawo za injini, makina otulutsa mpweya, uvuni wamafakitale, ndi zida zopangira magetsi pomwe mphamvu yothirira komanso nthawi yayitali. kupewa dzimbiri zofunika.

4. Kufananiza Magwiridwe

Gome ili pansipa likufanizira Dacromet ndi zokutira zina zomwe zimagwiritsidwa ntchito pamaboti a hexagonal:

Table 1. Mitundu yodziwika bwino ya zokutira pazitsulo zazitsulo zokhala ndi hexagonal. Zotsatira zenizeni zimasiyana malinga ndi ndondomeko ndi makulidwe.

5. Zomwe Zimagwira Ntchito

Zikomo kwa wapamwamba anti-corrosion, odana ndi dzimbiri, kukana kutentha, komanso kumasuka ku hydrogen embrittlement, Dacromet hexagonal bolts amagwiritsidwa ntchito kwambiri mu:

5.1 Makampani Oyendetsa Magalimoto

Zida za chassis, makina oyimitsidwa, mabuleki ophatikizika, zoyikira injini, ndi ntchito zapansi panthaka. Izi mabawuti ayenera kukana mchere wamsewu, chinyezi, kupalasa njinga, ndi kugwedezeka. Kusowa kwa hydrogen embrittlement n'kofunika kwambiri kwa kalasi ya 10.9 yamphamvu kwambiri ndi 12.9 fasteners pamagulu okhudzana ndi chitetezo.

5.2 Zomangamanga, Zomangamanga & Zomangamanga Zolemera

Milatho, zida zachitsulo, nsanja zotumizira, makina opangira mphepo, ndi makina olemera zimafunikira nthawi yayitali kukana dzimbiri. Maboti a Dacromet hexagonal amapereka odalirika kupewa dzimbiri panja ndi m'madera a m'mphepete mwa nyanja kwinaku mukusunga zoyenera komanso kuchita bwino kwambiri.

5.3 Zachilengedwe Zapanyanja, Zakunyanja & Zamankhwala

Kupopera mchere, chinyezi chosalekeza, komanso kukhudzana ndi mankhwala ndizofunikira kwambiri anti-corrosion ntchito. Maboti a Dacromet-wokutidwa ndi hexagonal amagwira ntchito pazida za sitima zapamadzi, nsanja zakunyanja, zida zamadoko, ndi zomangira zomangira zopangira pomwe zokutira wamba za zinki zimalephera mwachangu.

5.4 Ntchito Zina Zamakampani

Zida za njanji, zida zaulimi, zida zopangira mphamvu zamagetsi, ndi makina ambiri akumafakitale onse amapindula ndi kuphatikiza mphamvu zamakina, kulondola kwa mawonekedwe, komanso kulimba. odana ndi dzimbiri chitetezo choperekedwa ndi Dacromet hexagonal bolts.

6. Mapeto

Maboti a Dacromet hexagonal amapereka yankho lapadera pamapulogalamu omwe amafunikira makina apamwamba kwambiri komanso opambana. anti-corrosion ndi odana ndi dzimbiri chitetezo. Ndi kukana kupopera mchere nthawi zambiri kupitilira maola 1,000, chiwopsezo cha zero hydrogen embrittlement, kukana kutentha mpaka 300 ° C, komanso kuphimba kocheperako komwe kumasunga ulusi wokwanira, wokutidwa ndi Dacromet. mabawuti gonjetsani malire a plating yachikhalidwe ya zinki ndipo nthawi zambiri amaposa galvanizing otentha m'madera ovuta.
