1. Nhanganyaya kuDacromet Hex Bolts

Dacromet hexagon bolts inomiririra yemhando yepamusoro-yekuita kirasi yezvitsigiro zvakagadzirirwa kusarudzika kusagadzikana kwekuora uye yenguva refu yekudzivirira ngura. Aya mabhaudhi anosanganisa kuvimbika kwemuchina weakajairwa hexagonal-musoro mabhaudhi ane advanced zinc-aluminium flake coating inozivikanwa seDacromet (inonziwo Dacro kana zinc-flake coating). Mhedzisiro iyi bhaudhi inopa yakanakisa anti-corrosion kuita munzvimbo dzakaomarara uchichengetedza chaiyo tambo geometry uye yakakwirira tensile simba.

Kusiyana neakajairika electro-galvanized kana inopisa-dip galvanized mabhaudhi, Dacromet hexagon bolts anoshandisa isiri-electrolytic coating process. Izvi zvinobvisa njodzi yehydrogen embrittlement-yakakosha mukana wepamusoro-simba mabhaudhi emagiredhi 8.8, 10.9, uye 12.9. Iyo yakaonda, yunifomu yeDacromet firimu (kazhinji 4-12 μm) inopa yakakwirira yemunyu-spray kuramba, kupisa kupisa, uye yakazara anti-ngura kusimba, ichiita mabhaudhi aya sarudzo inosarudzika mumotokari, kuvaka, simba remhepo, marine, uye maindasitiri emidziyo yekushandisa.

2. Chii chinonzi Dacromet Coating?

Dacromet is inorganic, mvura-based metal surface treatment tekinoroji inosanganisira kunyanya-yakanaka zinc flakes, aluminium flakes, uye chromium-based binders. Kana yaiswa kune hexagon bhaudhi uye ichiporeswa patembiricha yakakwira (inoda kusvika 300 °C), maflakes anonangana muzvikamu zvakawanda zvakapiringana, achigadzira dense, simbi yesirivha-grey barrier. Iyi yakawanda-layer chimiro inogadzira zvese chipingamupinyi chemuviri kurwisa hunyoro uye electrolytes uye yekupira anodic yekudzivirira nzira iyo inoshingairira kuramba kuumbwa kwemarara.

Iyo yekupfekedza paDacromet hexagon bolt inopa dziviriro mbiri: iyo zinc flakes inoshanda sechibairo anode, inoora zvakanyanya kuchengetedza simbi substrate, nepo aluminium flakes uye inorganic matrix inosimudzira zvipingamupinyi uye inovandudza kugwinya kwese kuramba. Nokuti iyo nzira haisi-electrolytic, hapana hydrogen inounzwa musimbi yesimbi, inochengetedza yakazara mechanical kutendeseka kwepamusoro-simba mabhoti.

3. Dacromet Coating Process yeHexagon Bolts

Kugadzirwa kweDacromet hexagon bolt yakavimbika kunotevera kurongeka kwakanyatso kurongeka kwakagadzirirwa kuwedzera kunamatira, kufanana, uye anti-corrosion kuita:

1.Kugadzirira Kwepamusoro: Iyo bhaudhi inonatswa nekunatswa uye mechanika kana alkaline derusting. Acid pickling inodziviswa nemaune kudzivirira kutorwa kwehydrogen iyo inogona kutungamirira mukuputira kwepamusoro-simba mabhaudhi.

2.Coating Application: Iwo akacheneswa hexagon mabhaudhi anonyudzwa mukati, apfapfaidzwa nawo, kana kunyura-spun mumvura-based Dacromet slurry ine zinc uye aluminium flakes. Dip-spin ndiyo yakajairika maindasitiri nzira yekuwanda kugadzirisa mabhoti.

3.Kuporesa / Sintering: Mabhaudhi akavharwa anobikwa paanenge 300 ° C. Panguva yekurapa bhainda rinoita uye simbi inoputika inopinda muinoenderera, yakasimba inonamatira inorganic film.

4.Quality Inspection: Yakapedzwa Dacromet hexagon mabhaudhi anotariswa kuti akafukidzira ukobvu, kunamatira, kutaridzika, uye munyu-spray kuita kuti ive nechokwadi chekuchengetedzwa kwekudzivirira ngura.

4. Kuita Kuenzanisa kweAnti-Corrosion Coatings

Tafura inotevera inopfupikisa misiyano yakakosha pakati peDacromet hexagon bolts uye mabhaudhi akapedzwa nemaitiro echinyakare ekurwisa ngura:

Property	Dacromet	Electro-Galvanizing	Hot-Dip Galvanizing
Coating Ukobvu	4–12 μm	5–15 μm	40–85 μm
Salt Spray (hapana tsvuku tsvuku)	600–1,200+ h	100–300 h	500–800 h
Hydrogen Embrittlement Ngozi	Hapana	Yakakwirira (inoda kubika)	Low–Medium
Heat Resistance	Kusvikira ku300 ° C	≤ 100–120 °C	≤ 200 °C
Thread Fit Impact	Minimal / Standard nzungu OK	Minimal	Yakakosha (ingangoda kuwandisa)
Environmental Profile	Mvura-based, kusvibiswa kwakaderera	Kugadziriswa kwemvura yetsvina kunodiwa	Zinc slag / wastewater

5. Yakajairika Mashandisirwo eDacromet Hexagon Bolts

Nekuda kwekushomeka kwavo kusimba kwekuora, hydrogen-embrittlement-isina hunhu, uye nedimensional kurongeka, Dacromet hexagon bolts inotsanangurwa zvakanyanya muzvikamu zvinoda:

Mota dzemotokari uye dzekutengesa: Zvikamu zveinjini, chassis, kumiswa, uye pasi pemuviri zvinosungirira izvo zvinofanirwa kuramba munyu wemugwagwa uye hunyoro.
Simba reMhepo uye simba rinogonekazve: Shongwe, nacelle, uye nheyo mabhoti akaoneswa kumahombekombe kana kumahombekombe ekunze.
Kuvaka uye zvivakwa: Zvimiro zvekubatanidza, mabhiriji, uye simbi yekunze inoda kushanda kwenguva refu kwekudzivirira ngura.
Marine uye offshore: Zvishandiso uye mabhaudhi ezvimiro zviri pasi pemamiriro ekunze akazara nemunyu.
Industrial muchina uye inorema midziyo: Yakakwirira-yakasimba mabhaudhi majoini munzvimbo umo kuvimbika kwemechini uye kuchengetedzwa kwekuora kwakakosha.

6. Mamiriro ehunyanzvi uye data rekuita

Maitiro ekuita zviratidzo zveDacromet-yakavharwa hexagon mabhoti akapfupikiswa pazasi. Hunhu chaihwo hunoenderana negiredhi rekupotera (semuenzaniso, Dacromet 320 kana 500) uye maitiro ekugadzirisa.

7. Mhedziso

Dacromet hexagon bolts inopa yazvino, yepamusoro-inoshanda mhinduro yezvikumbiro inoda ese ari maviri epamusoro mechanicha simba uye yakasarudzika yekureba-kuora kuramba. Nekubatanidza yakatetepa, isiri-electrolytic zinc-aluminum flake coating nechaiyo hexagonal geometry, mabhaudhi aya anobvisa njodzi yehydrogen-embrittlement uku achiendesa munyu-spray kuramba zvakakwirira kudarika zvakajairika electro-galvanizing. Kuramba kwavo kupisa kwakanyanya, kuenderana kweshinda, uye hushamwari hwezvakatipoteredza zvinowedzera kukosha kwavo muzvikamu zvemotokari, simba, kuvaka, uye maindasitiri.

Paunenge uchitsanangura zvigadziro zvenzvimbo dzinosvibisa sevhisi, mainjiniya nevatengi vanowedzera kutendeukira kuDacromet-yakavharwa hexagon mabhoti seyakavimbika, inorwisa-ngura sarudzo inodzivirira majoini akakosha kwemakumi emakore. Yakafanira maitiro ekutonga uye kuoneswa kwemhando inovimbisa kuti bhaudhi rega rega rinoburitsa yakazara corrosion-yekudzivirira kuita iyo iyo Dacromet tekinoroji inozivikanwa nayo.

Muchidimbu, iyo Dacromet hexagon bolt inomira seyakabvumikiswa, inodhura-inoshanda, uye tekinoroji yepamusoro-yekudzivirira-corrosion fastener kune inonyanya kudiwa maapplication.
