ʻO DACROMET HEXAGON BOLTS-Nā Hoʻopaʻa Paʻa Kūʻē Kūʻē Kūʻē 

ʻAʻole e like me nā bolts electro-galvanized a i ʻole hot-dip galvanized bolts, hoʻohana ʻo Dacromet hexagon bolts i kahi kaʻina hana uhi ʻole electrolytic. Hoʻopau kēia i ka pilikia o ka hoʻoheheʻe ʻana o ka hydrogen—he pono koʻikoʻi no nā bolts ikaika kiʻekiʻe o nā papa 8.8, 10.9, a me 12.9. ʻO ke kiʻi ʻoniʻoni Dacromet lahilahi (maʻamau 4-12 μm) hāʻawi i ke kūpaʻa paʻakai paʻakai, pale wela, a me ka lōʻihi anti-rust holoʻokoʻa, e hoʻolilo ana i kēia mau bolts i ka koho i makemake ʻia i nā kaʻa, ke kūkulu ʻana, ka ikehu makani, ka moana, a me nā mea hana ʻenehana.

2. He aha ka Dacromet Coating?

ʻO Dacromet kahi ʻenehana hoʻomaʻamaʻa ʻana i ka ʻili o ka wai me ka wai me ka nui o nā flakes zinc ultra-fine, flakes aluminika, a me nā mea hoʻopili chromium. Ke hoʻohana ʻia i ka bolt hexagon a hoʻōla ʻia ma kahi wela kiʻekiʻe (ma kahi o 300 °C), e hoʻopili ʻia nā flakes i loko o nā ʻāpana overlapping he nui, e hana ana i kahi pale, metala hina hina. Hoʻokumu kēia ʻano hana multi-layer i kahi pale kino e kūʻē i ka makū a me nā electrolytes a me kahi mīkini pale anodic kaumaha e kūʻē ikaika i ka hoʻokumu ʻana i ka ʻōpala.

Hāʻawi ka uhi ʻana i kahi bolt hexagon Dacromet i ka pale ʻelua: ʻo ka zinc flakes e hana ma ke ʻano he anode mōhai, ʻoi aku ka maikaʻi o ka corroding no ka pale ʻana i ka substrate kila, ʻoiai nā flakes aluminika a me ka matrix inorganic e hoʻomaikaʻi i nā waiwai pale a hoʻomaikaʻi i ka pale ʻana i ka corrosion holoʻokoʻa. No ka mea he non-electrolytic ke kaʻina hana, ʻaʻohe hydrogen i hoʻokomo ʻia i loko o ka lattice kila, e mālama ana i ka pono mechanical piha o nā bolts ikaika kiʻekiʻe.

3. ʻO ke kaʻina hana hoʻopili ʻo Dacromet no nā Hexagon Bolts

ʻO ka hana ʻana o kahi bolt hexagon Dacromet hilinaʻi e hahai ana i kahi kaʻina mālama pono i hoʻolālā ʻia e hoʻonui i ka adhesion, kūlike, a me ka hana anti-corrosion.

1. Hoʻomākaukau ʻana i ka ʻili: Hoʻomaʻemaʻe maikaʻi ʻia ka bolt a me ka mechanical a alkaline derusting. ʻAʻole ʻae ʻia ka ʻai ʻana i ka ʻakika i mea e pale ai i ka absorption hydrogen i hiki ke alakaʻi i ka embrittlement o nā kī ikaika kiʻekiʻe.

2. Hoʻopili i ka noi: Hoʻokomo ʻia nā pōkā hexagon i hoʻomaʻemaʻe ʻia i loko, kāpīpī ʻia me, a i ʻole i wili ʻia i loko o kahi slurry Dacromet i hoʻokumu ʻia i ka wai me ka zinc a me nā flakes alumini. ʻO Dip-spin ke ʻano hana maʻamau no ka hana nui ʻana o nā bolts.

3. Hoʻomaʻamaʻa / Sintering: Hoʻomoʻa ʻia nā bolts i uhi ʻia ma kahi o 300 ° C. I ka wā o ka ho'ōla ʻana, hoʻololi ka mea hoʻopili a hoʻopaʻa ʻia nā ʻāpana metala i loko o kahi kiʻiʻoniʻoni inorganic paʻa mau.

4.Quality Inspection: Hoʻopaʻa ʻia nā bolts hexagon Dacromet i hoʻopau ʻia no ka uhi ʻana i ka mānoanoa, adhesion, hiʻohiʻona, a me ka hana paʻakai-paʻakai e hōʻoiaʻiʻo i ka pale kūʻokoʻa.

4. Ka Hoʻohālikelike Hana ʻana o nā Kāpena Anti-Corrosion

Hōʻuluʻulu ka papa ma lalo nei i nā ʻokoʻa nui ma waena o Dacromet hexagon bolts a me nā bolts i hoʻopau ʻia me nā ʻano anti-rust kuʻuna.
