Dacromet Flange Bolts-Anti-Corrosion Flange Fasteners e nang le Zinc-Aluminium Flake Coating 

Karolo ea 1 - Flange Bolt Overview

Flange Bolt ke Eng?

Bolt ea flange ke bolt ea hlooho ea hex e nang le letlapa le kopaneng la washer botlaaseng ba hlooho. Flange e aba moroalo oa ho koala holim'a sebaka se pharaletseng, ho fokotsa khatello ea holim'a thepa e kopantsoeng le ho thibela tšenyo ea libaka tse bonolo kapa tse pentiloeng. Sena se felisa tlhoko ea washer e arohaneng ea sephara, ho nolofatsa kopano le ho fokotsa palo ea likarolo.

Lintlha tsa Moqapi oa Bohlokoa

Integral flange: E fana ka matla a ho tiisa holim'a sebaka se seholo ho feta hlooho e tloaelehileng ea hex, ho fokotsa khatello ea maikutlo le ho thibela ho ikatisetsa holimo.

Khetho e hlophisitsoeng: Serrated flange e loma bokaholimo ba ho nyalana, e fana ka khanyetso e hahelletsoeng ka har'a e thibelang ho lokoloha ntle le likarolo tse ling tsa ho notlela.

Litekanyo tse emeng: E entsoe ho DIN 6921, ISO 4162, kapa GB/T 5787, e netefatsang phapanyetsano ho pholletsa le liketane tsa phepelo tsa lefats'e.

Limaraka tse phahameng haholo: E fumaneha ka sehlopha sa thepa ea 8.8 le 10.9, e loketseng bakeng sa likopo tsa moralo le ho jara mojaro.

Litlhaloso

Karolo ea 2 - Dacromet Coating Technology

Dacromet (达克罗) ke phekolo e thehiloeng metsing, e seng ea electrolytic e behang filimi e tšesaane ea li-zinc le li-flakes tsa aluminium tse kopantsoeng ke metsoako ea inorganic chromium. E sebelisoa ka mokhoa oa dip-spin-cure, e fana ka mekhahlelo e mengata ea ts'ireletso ea kutu ntle le ho kenya haedrojene ka har'a tšepe - molemong oa bohlokoa bakeng sa li-fasteners tse matla haholo.

Mokhoa oa Tšireletso ea Corrosion

Tšireletso ea sehlabelo: Li-flakes tsa zinc li senya ka ho khetheha ho sireletsa karolo ea tšepe ea tšepe, esita le ha seaparo se phunyeletsoa.

Tšitiso ea 'mele: Li-flakes tsa zinc-aluminium tse pota-potiloeng li etsa tsela e boima e thibelang mongobo, oksijene le li-ion tse senyang.

Phaello ea lik'hemik'hale: Metsoako ea chromium e etsa lera le sa sebetseng le fokotsang ho qhibiliha ha zinki le ho ipholisa ha mekhoro e menyenyane.

Melemo ea Bohlokoa bakeng sa Flange Bolts

Ha ho na hydrogen embrittlement: Ts'ebetso e seng ea electrolytic - e bolokehile bakeng sa liboutu tsa flange tsa Kereiti ea 8.8-10.9 moo electroplating e thibetsoeng.

O mosesaane & o tšoanang: Ho roala ha 4–10 µm ho boloka khoele e lekana le geometry ea flange. Ha ho hlokehe ho tlanya linate hape.

500-1,200 lihora tsa ho fafatsa letsoai: 5-10 makhetlo a betere ho feta plating e tloaelehileng ea zinki, e loketseng ho pepeseha ka ntle ka nako e telele.

E thibela mocheso: E mamella ts'ebeletso e tsoelang pele ho fihla ho 250°C - e loketse sebaka sa enjine le li-fasteners tse haufi.

E lumellana le tikoloho: Ha e na Cr⁶⁺, RoHS le REACH lia lumellana.

Coating Papiso

Ho fafatsa letsoai ho latela ISO 9227 NSS. Kotsi ea hydrogen embrittlement e sebetsa ho li-fasteners tsa electroplated Kereiti ea 10.9 le ho feta.

Kakaretso

Li-bolts tsa Dacromet flange li fana ka motsoako o qobellang oa ts'ebetso ea mochini le ts'ireletso ea kutu. Flange ea bohlokoa e nolofatsa kopano ha e ntse e aba mojaro ka mokhoa o ts'oanang, 'me seaparo sa Dacromet zinc-aluminium flake se fana ka lihora tse 500-1,200 tsa ho hanyetsa spray ea letsoai ntle le hydrogen embrittlement. Li-fasteners tsena li sebelisoa haholo mesebetsing ea likoloi, kaho, matla a moea, le lits'ebetsong tsa leoatle moo ts'ebetso e tšepahalang ea ho koala le ho tšoarella ha nako e telele li bohlokoa.
