Maboti a Dacromet Hex Socket: Kupaka Kwapamwamba Kwambiri kwa Anti-Corrosion Kukumana ndi Mapangidwe Okhazikika Okhazikika

2026-07-27

Dacromet hex socket bolts imayimira kusinthika kwa matekinoloje awiri ofunikira kwambiri: Dacromet high-performance anti-corrosion coating system ndi cylindrical socket-head (Allen) bolt geometry. Pamodzi, amapereka njira yolumikizira yomwe imalimbana ndi madera owononga kwambiri pomwe imathandizira kukhazikitsa kokwezeka kolondola kwambiri, kuwapangitsa kukhala ofunikira pamagalimoto, apamadzi, zomangamanga, ndi makina olemera padziko lonse lapansi.

1. Dacromet Coating Technology

Dacromet ndi makina opangira madzi opangidwa ndi madzi omwe adapangidwa kuti apange zomangira za kaboni ndi zitsulo zosapanga dzimbiri. Mosiyana ndi zinki wamba wa electroplated, Dacromet imagwiritsa ntchito njira yamankhwala yopanda chromium (kapena yotsika chromium) yomwe imapanga chotchinga chomangika chambiri cha zinki ndi ma aluminium flakes. Zotsatira zake ndi kumaliza kwapadera kwa silver-gray komwe kumaphatikiza kusalowerera ndale ndi chitetezo chapadera.

Magawo atatuwa amagwira ntchito mogwirizana kuti apereke chitetezo chokwanira:

Zinc-aluminum flake base layer – imapereka chitetezo cha nsembe (cathodic), corroding makamaka kuteteza gawo lapansi lachitsulo, pamene ma aluminium flakes amawonjezera chitetezo chotchinga.

Passivation mid-layer – filimu ya inorganic chromate/silicate yomwe imamata zitsulo za flake, kukana kupopera mchere, kuwononga mankhwala, ndi kutentha kupitirira plating wamba.

Coat organic seal coat (posasankha) – imathandizira kuti musamagwire bwino ntchito komanso kuti isalimbane ndi nyengo, kwinaku ikupanga mawonekedwe a silver-gray mosasinthasintha komanso kugunda kocheperako.

Table 1. Kuyerekeza kwa Corrosion Resistance (Kuyesa Kupopera Mchere, NSS)

Mtundu Wopaka	Maola Opopera Mchere	Makulidwe (μm)	Kugwiritsa Ntchito
Dacromet	≥ 1,000 - 3,000	6-10	Marine / magalimoto
Ruspert	≥ 1,000 - 3,000	3 - 5	Panja / m'madzi
Zn-Ni alloy plating	≥ 720 - 1,000	8-12	Zagalimoto
Zn plating wamba	96-240	5-8	Indoor / general

2. Maboti a Hex Socket

Mabowuti a hex socket, omwe amadziwikanso kuti socket head cap screws kapena Allen bolts, amakhala ndi mutu wa cylindrical wokhala ndi ma hexagonal drive mkati. Geometry iyi imalola kufalikira kwa torque yapamwamba yokhala ndi mbiri yaying'ono yamutu poyerekeza ndi mabawuti akunja a hex, kuwapangitsa kukhala abwino kwa mapulogalamu omwe alibe chilolezo chochepa kapena pomwe mawonekedwe owoneka bwino amafunikira.

Zofunikira zazikulu zamapangidwe ndi:

Mutu wozungulira wokhala ndi ma hex drive mkati - umavomereza makiyi a hex okhazikika kuti akhazikitse ma torque apamwamba okhala ndi mutu wocheperako; kukula kwa galimoto kumagwirizana ndi ISO 2936 kapena ASME B18.3.

Ulusi wathunthu kapena pang'ono – mitundu yosiyanasiyana ya ulusi wonse imagawira katundu mofanana muutali wolumikizidwa; mitundu ya ulusi wapang'ono imapereka shank yamphamvu yosawerengeka pamagwiritsidwe ntchito kameta.

Chitsulo champhamvu kwambiri (8.8 / 10.9 / 12.9) – magiredi otenthetsera amatsimikizira kulimba kwamphamvu mpaka 1,220 MPa, yoyenera katundu wosunthika ndi malo olumikizirana ovuta kwambiri.

Dacromet surface finish – imapereka chitetezo cha maola ≥ 1,000 opopera mchere popanda kusungunula wa hydrogen, kupangitsa kuti ikhale yabwino kwa zomangira zamphamvu kwambiri komwe electroplating ndi yosayenera.

Kukula	Thread Dia. (mm)	Kutalika Kwamutu (mm)	Min. Tensile (MPa)	Kugwiritsa Ntchito
M4	4	4	800	Zamagetsi / zida
M5	5	5	800	Msonkhano wopepuka
M6	6	6	800	Mipando / makina
M8	8	8	800	Makina / magalimoto
M10	10	10	830	Zomangamanga
M12	12	12	830	Makina olemera

3. Mwachidule

Maboti a Dacromet hex socket amaphatikiza kukana kwamphamvu kwa dzimbiri kwa Dacromet inorganic coating system (kukwaniritsa maola 1,000-3,000 achitetezo chopopera mchere popanda hydrogen embrittlement) ndi mawonekedwe apamwamba, otsika kwambiri a bawuti ya hex socket. Kuphatikizikaku kumathandizira kukhazikika kodalirika m'malo ovuta - kuchokera ku ma chassis ndi ma brake system kupita kuzinthu zam'madzi ndi zida zakunja - ndikusunga kuwongolera kolondola kwa torque komanso kukhazikika kwanthawi yayitali. Pamene mafakitale akuchulukirachulukira kufunafuna zomangira zomwe zimagwira ntchito bwino, chitetezo, komanso moyo wautali, ma bolts a Dacromet hex socket akhala chisankho chokondedwa kwa mainjiniya ndi ma OEM padziko lonse lapansi.
