Goorma ayay tahay in Bolts-ku-xidhka ay isticmaalaan Dacromet?

2026-06-15

Tilmaan wax ku ool ah oo lagu dooranayo boolal-saldhig-Dacromet-dahaarka leh, boolal-saldhig, bolts hex, iyo xirayaasha xiraha ee jawiyada warshadaha ee daxalka leh iyo kuwa baahida sare leh.

WAA MAXAY DACROMET COATING?

Dacromet (sidoo kale loo higaadiyay Geomet ama Dacrotized) waa daahan biyo-ku-saleysan, chromium-free zinc-flake daahan oo lagu dhejiyay xirmayaasha birta kaarboon- oo ay ku jiraan boolal-barroosinno, boolal-saldhig, boolal-korka, boolal hex, boolal flange, lowska, iyo dhaqida. Filimka khafiifka ah, qalin-cawlan (sida caadiga ah 8-12 µm) wuxuu bixiyaa caabbinta milixda-buufinta oo aad u wanaagsan in ka badan 720 saacadood, aad uga sarreeya galvanizing-kuleelka caadiga ah ama korantada qaybaha dunta leh sida M12-M72 hex boolal iyo boolal.

MUUQAALAHA CODSIGA MUHIIMKA AH EE DACROMET BOLTS

Doorashada daahanka Dacromet ee guntimaha aasaasiga ah iyo xidhidhiyeyaasha qaabdhismeedku waxa ugu cadcad lixdan xaaladood ee soo socda:

SCENARIO	FAAHFAAHINTA & NOOCYADA DEJINTA
Xeebaha & Deegaanka Badda	Buufinta biyaha cusbadu waxay daxalisay birta kaarboonka ee aan la ilaalinayn iyo furayaasha toddobaadyo gudahood. Dacromet bolts - laga bilaabo M16 bolts ilaa bolts M48 - waxay iska caabiyaan weerarka chloride, iyaga oo ka dhigaya dooqa koowaad ee wiishashka dekedaha, meelaha xeebaha ah, dhismayaasha jetty-ga, iyo munaaradaha dabaysha ee badda.
Batroolka Kiimikada & Dhirta Kiimikada	Aasaaska reactor, taageerooyinka dhuumaha, iyo boolalka barroosinka waxay la kulmaan asiidh, alkalis, iyo qiiqa kiimikaad. Dacromet-ku-daboolan boolal culus oo hex ah iyo boolal udgoon (Fasalka 8.8 / 10.9) waxay ilaalinayaan daacadnimada halka dhejinta zinc caadiga ah ay ku guuldareysato, yareynta dayactirka aan la qorsheyn ee qalabka habka muhiimka ah.
Dabaysha & Qaab-dhismeedka Korontada Qorraxda	Baqashada barroosinka Tower iyo boolal qoraxda lagu xidho waa inay ku jiraan 20+ sano oo bannaanka ah. Dacromet dacromet on M30-M72 boolal-barroosinka ayaa meesha ka saaraya khatarta ebrittlement hydrogen ee la xiriirta koronto-la'aanta - lagama maarmaan u ah xoogga sare (Fasalka 10.9) bolts qaabdhismeedka loo isticmaalo aasaaska marawaxadaha.
Jidka, Buundada & Kaabayaasha Tunnel	Kala-goysyada balaadhinta, biraha ilaalada, boolal-biyoodka, iyo barroosinnada dhagxaanta tunnel-ka waxay wajahaan cusbada waddada, kiimikooyinka wax-ka-gooya, iyo biyaha dhulka hoostiisa. Xidhiidhiyayaasha Dacromet waxay u hoggaansamaan heerarka ilaalinta daxalka ee dhismayaasha birta ee waddooyinka waaweyn iyo mashaariicda buundooyinka tareenka.
Baabuur & Qalab Culus	Xirmooyinka aasaasiga ah ee Chassis, boolal-hakinta, iyo xirayaasha nidaamka biriiga waxay u baahan yihiin dahaar-filim khafiif ah oo ilaalinaya dulqaadka dunta saxda ah. Labbiska Dacromet ee lakabka 8 µm ma beddelo ku habboonaanta lowska-bolt-ka ee muraayadaha dunta-fiican ee M8-M24, si ka duwan dahaarka galvanized-kulka-lufka ah ee dhumuc weyn leh.
Barroosinnada la taaban karo ee Dhulka hoostiisa ku jira	Dhalooyinka barroosinka ayaa lagu tuuray aasaaska shubka ah ee mishiinada culus, tiirarka birta, iyo dhismayaal hore loo sii hagaajiyay ayaa ka faa'iidaysanaya ku-xidhka Dacromet ee birta iyo la jaanqaadka bay'ada sibidhka. Tani waxay si gaar ah qiimo ugu leedahay J-bolts, L-bolts, iyo ulaha barroosinka madax ka ah ee aasaaska warshadda warshadaha.

DACROMET VS. KULUL-DIP GALVANISING: is barbardhig degdeg ah

HANTIDA	DACROMET	KULUL-DIP GALVANIZING
Dhumucda dahaarka	8-12 µm	45-85 µm
Dulqaadashada dunta	Aan la taaban	Waxay u baahan kartaa dib-u-taabsi
Iska caabinta milixda-buufinta	≥ 720 saac	≥ 500 saacadood (caadi)
H₂ Ebrittlement	Midna	Macquul ah (electrolating)
Heerkulka Shaqada	Ilaa 300 °C	Ilaa 200 °C
Cabbirrada Bolt ee caadiga ah	M6–M72	M10–M100
Ugu Wanaagsan	Xadhkaha saxda ah, xooga sare Fasalka 10.9 boolal, boolal dhuuban	Bir qaab-dhismeed, boolal waaweyn oo barroosin ah
