Dacromet Hexagonal Bolts | Technical Overview 

1. Nhanganyaya

Hexagonal mabhaudhi, anowanzozivikanwa sehex bolts, ari pakati pezvinonyanya kushandiswa zvekusungirira muinjiniya nekuvaka. Kana yakasimudzirwa neDacromet coating tekinoroji, aya mabhaudhi anoburitsa yakasarudzika corrosion kuramba, kutendeseka kwemuchina, uye kuvimbika kwenguva refu kunyangwe munzvimbo dzakaomarara. Ichi chinyorwa chinopa tsananguro yakadzama yeDacromet hexagonal bolts, inovhara kuumbwa kwavo, zvakanakira, maitiro ekugadzira, hunyanzvi hwekuita, uye maindasitiri ekushandisa.

Dacromet ndeye proprietary zinc-flake coating system yakatanga kugadzirirwa indasitiri yemotokari. Iyo ine zinc uye aluminium flakes yakasungwa neinorganic chromate matrix. Kusiyana nechinyakare electroplating kana hot-dip galvanizing, iyo Dacromet muitiro haisi-electrolytic, zvichiita kuti mutete asi akanyatsoshanda anodzivirira akaturikidzana isingakudze hydrogen embrittlement-yakakosha mukana kune yakakwirira-simba fasteners.

Chii chinonzi Dacromet Coating?

Dacromet (inonziwo zinc-flake coating) ndeyemvura-yakavakirwa, inorganic coating yakagadzirwa kubva zinc powder, aluminium poda, uye chromate binders. Inoshandiswa kuburikidza ne dip-spin kana kupfapfaidza process inoteverwa nepamusoro-tembiricha yekurapa (inoda kusvika 300 ° C), iyo yekuisa inoumba yakawanda-layered chipingamupinyi chinopa cathodic dziviriro, chipingamupinyi chekudzivirira, uye hunhu hwekuzviporesa.

Yakajairika yakaoma-firimu ukobvu hunobva pa 4 kusvika ku 12 micrometres, yakatetepa kupfuura yakajairwa inopisa-dip galvanizing (50–80 μm). Pasinei nehuwandu hwayo hutete, nzvimbo dzakaputirwa neDacromet dzinogara dzichitsungirira maawa anopfuura 1,000 ekuongororwa kwemunyu-spray pasina kuonekwa kwehutu tsvuku.

2. Mabhenefiti Akakosha eDacromet Hex Bolts

Dacromet hexagonal bolts inopa yakasarudzika musanganiswa wezvivakwa zvinopfuura akawanda echinyakare epamusoro kurapwa:

• Superior Corrosion Resistance: Kuita kwemunyu-pfayiro kunodarika 1,000–1,200 maawa (ISO 9227 / ASTM B117), ingangoita 7–10 nguva zviri nani pane yakajairwa electro-galvanizing.
• Hapana Hydrogen Embrittlement: Iyo isiri-electrolytic process inobvisa hydrogen absorption, zvichiita kuti Dacromet yakanakira mabhaudhi epamusoro-soro (Grade 8.8, 10.9, 12.9 uye ASTM A490).
• High-Temperature Kugadzikana: Kuenderera mberi kwekushanda kwekushisa kusvika ku300 ° C pasina kusvibiswa kwefirimu yekudzivirira-kure kure kune yakajairwa zinc coatings.
• Yakanakisa Thread Fit & Dimensional Kugadzikana: Yakatetepa yekupfeka inochengetedza shinda geometry uye inobvumira kuungana kwakatsetseka nenzungu dzakajairwa.
• Yakanaka Paintability & Recoatability: Kunamatira kwakasimba kune organic topcoats inogonesa kuwedzera kunaka kana kushanda kupedzisa.
• Bimetallic kuenderana: Inoita zvakanaka mukusangana nealuminium uye mamwe masimbi akasiyana, kuderedza galvanic corrosion njodzi.

3. Manufacturing Process

Iyo Dacromet yekupfekedza maitiro eiyo hexagonal mabhaudhi inonyatso inodzorwa kutevedzana inova nechokwadi chekuvhara yunifomu uye kuita kwakanyanya:

1. Kugadzirira Kwepamusoro: Mabhaudhi anonyatsocheneswa uye kucheneswa kubvisa mafuta, okisidhi, uye zvinosvibisa. Hapana asidi pickling inodiwa, zvichiwedzera kuderedza njodzi yehydrogen.
2. Dip-Spin Application: Zvikamu zvinonyudzwa muiyo aqueous Dacromet kuturika uye zvino spun nekumhanya kwakadzora kuti uwane yunifomu yefirimu ukobvu uye kubvisa yakawandisa coating.
3. Pre-Curing & Final Curing: Kupisa kwepasi-kupisa kusati kwabikwa kunoputika mvura, inoteverwa nepamusoro-tembiricha sintering (~ 300 ° C) iyo inosanganisa zinc-aluminum flakes kuita dense, inonamatira coating.
4. Kuongorora Kwemhando: Coating ukobvu, adhesion (muchinjika-yakatemwa bvunzo), kutaridzika, uye munyu-yekupfapfaidza sampling inoitwa kuvimbisa batch kuenderana.

4. Mamiriro eUnyanzvi & Maitiro

Dacromet hexagonal bolts inogadzirwa kune dzakasiyana siyana dzepasirese zviyero uye inowanikwa mune akawanda ezvivakwa makirasi.

5. Industrial Applications

Nekuda kwemusanganiswa wavo wakatanhamara wesimba uye corrosion kuramba, Dacromet hexagonal bolts inotsanangurwa munzvimbo dzakawanda dzinodiwa:

6. Mhedziso

Dacromet hexagonal bolts inomiririra yakura, yakakwirira-inoshanda yekusimbisa mhinduro inovhara mukaha pakati pezvakajairwa zinc coatings uye inodhura dzimwe nzira senge simbi isina tsvina kana specialized alloy masisitimu. Tekinoroji yavo yefirimu-tete inopa kudzivirira kwakanakisa, inobvisa kunetseka kwehydrogen embrittlement, inochengetedza kushivirira chaiko, uye inoshingirira tembiricha yakakwira - hunhu hunovaita kuti huve hwakakosha mukuita kweinjiniya yemazuva ano.

Sezvo maindasitiri achiramba achida hupenyu hurefu hwebasa, kuderedzwa kugadzirisa, uye kuvimbika kwakanyanya pasi pehutsinye hwemamiriro ekunze, kutorwa kweDacromet-coated fasteners kunotarisirwa kuwedzera mberi. Nekusarudza giredhi rakakodzera, saizi, uye coating yakatarwa, vagadziri uye nyanzvi dzekutenga zvinhu vanogona kuwana zvese zvakanaka zvehunyanzvi uye kuita zvinodhura.

Kuti uwane kurudziro yakanangana neprojekiti kana tekinoroji data mapepa, bvunza vanokwanisa vanogadzira fastener uye nyanzvi dzekupfeka.
