ʻO Dacromet Coated Flange Bolts-He alakaʻi ʻenehana holoʻokoʻa no ka hoʻolālā ʻana, ka ʻenehana uhi a me nā noi ʻoihana. 

ʻOkoʻa ke kaʻina hana uhi Dacromet mai ka electroplating. Ma mua o ka waiho ʻana i ka metala ma o ka electrolysis, hoʻohana ʻo Dacromet i kahi dip-spin a i ʻole spray spray i ukali ʻia e ka mālama wela wela. I ka wā o ka mālama ʻana ma kahi o 280-320 degere Celsius, e hui pū ka zinc a me nā flakes alumini a hoʻopaʻa ʻia i ka substrate kila ma o kahi mīkini hoʻopili cross-mediated chromate. He lahilahi ka hopena o ka uhi (maʻamau 6-10 microns), ʻaʻahu, a pili loa.

3.1 Nānā Kaʻina Hana Uila

ʻO ke kaʻina hana noi Dacromet e pili ana i nā pae i hoʻomalu pono ʻia, e hāʻawi ana kēlā me kēia i nā hiʻohiʻona hana hope o ka uhi:

Papa 2. Nā ʻanuʻu kaʻina hana hoʻoheheʻe ʻo Dacromet

Hoʻopau maʻamau ke kaʻina hana holoʻokoʻa i ʻelua pōʻai uhi no ka loaʻa ʻana o ka mānoanoa o ka uhi i makemake ʻia a me ke kūpaʻa corrosion. Loaʻa i kēlā me kēia pōʻai me ka noi, ka maloʻo ʻana, a me ka hoʻōla ʻana, me ka huahana hope e hōʻike ana i kahi hiʻohiʻona hina hina.

4.Pono o ka Dacromet Coating

Hāʻawi ʻo Dacromet coating i nā mea maikaʻi ʻē aʻe ma mua o nā hoʻomaʻamaʻa maʻamau maʻamau, e hoʻolilo iā ia i koho i koho ʻia no nā noi paʻa kiʻekiʻe.

Kū'ē Kū'ē Kū'ē: Hiki i nā mea paʻa i uhiʻia e Dacromet ke kū i ka 1,000 a 3,000 mau hola o ka ho'āʻoʻana i ka paʻakai (ASTM B117) ma mua o kaʻikeʻiaʻana o ka'ōpalaʻulaʻula, iʻoi aku ka maikaʻi o ka zinc electroplating (300-700 hola).

ʻAʻohe Hydrogen Embrittlement: ʻAʻole e like me ka electroplating, ʻaʻole pili ke kaʻina hana Dacromet i ka electrolysis, e hoʻopau ana i ka pilikia o ka hydrogen embrittlement. He mea koʻikoʻi kēia no nā bolts kiʻekiʻe (Class 10.9 a me 12.9) i hoʻohana ʻia i nā noi palekana-koʻikoʻi.

Kū'ē Heat maikaʻi loa: ʻO ke ʻano inorganic o ka uhi Dacromet e hiki ai iā ia ke mālama i kāna mau mea pale i nā mahana a hiki i 300 degere Celsius, ʻoi aku ka nui o nā palena wela o nā uhi kūlohelohe a me ka plating zinc maʻamau.

ʻAi ʻAi ʻAi: ʻO ke ʻano o ka noi dip-spin e hōʻoiaʻiʻo i ka mānoanoa o ka uhi paʻa ʻana ma luna o nā geometries paʻakikī, me nā wahi i hoʻopaʻa ʻia a me nā wahi hoʻomaha kahi e hiki ai i ka electroplating ke hana i nā waiho like ʻole.

Ka Hoʻokō Kaiapuni: ʻAʻole nā ​​mea hana Dacromet o kēia manawa me ka hexavalent chromium (Cr6+), e hoʻokō ana i nā kuhikuhi RoHS, ELV, a me REACH, i kūpono ia no nā noi kaʻa a me ka uila.

5. Noi Hana Hana

Loaʻa ka hoʻohana nui ʻana o Dacromet coated flange bolts ma waena o nā ʻoihana he nui kahi i koʻikoʻi ai ka paʻa ʻana a me ka pale corrosion lōʻihi.

ʻOihana Kaʻa: Hoʻohana ʻia i nā hui chassis, nā puʻu mīkini, nā ʻōnaehana brake, a me nā ʻāpana hoʻomaha kahi e pono ai ka hoʻopaʻa ʻana i ka ikaika kiʻekiʻe me ka paʻakai paʻakai. Hōʻike nā OEM nui i nā mea paʻa i uhi ʻia ʻo Dacromet no nā noi ma lalo o ke kino i ʻike ʻia i ka paʻakai alanui a me ka wai.

Ke kūkulu ʻana a me ka ʻoihana: Hoʻohana ʻia i nā pilina pili kila, nā ʻāpana alahaka, a me nā lako waho kahi e hoʻemi ai ka hoʻolālā flange hoʻolaha ponoʻī i ka manawa hoʻonohonoho a hāʻawi ka uhi ʻo Dacromet i mau makahiki o ka lawelawe mālama ʻole.

ʻO ke kai a me ka waho: ʻO ke kūpaʻa paʻakai kūʻokoʻa o ka uhi ʻana o Dacromet (a hiki i 3,000 mau hola) e kūpono i kēia mau bolts no ka hana moku, nā kahua o waho, a me nā lako paʻa i ʻike ʻia i nā kaiapuni paʻakai mau.

Energy Energy: Hoʻohana ʻia i nā flanges hale kiaʻi turbine a me nā hui nacelle kahi e kū ai ka bolting ikaika kiʻekiʻe i ka hoʻouka ʻana a me ka ʻike kaiapuni ma kahi o 20+ mau makahiki lawelawe.

Kaaahi a me nā Mīkini Kaumaha: Hoʻohana ʻia i nā ʻōnaehana hoʻopaʻa track, nā ʻāpana locomotive, a me nā lako mining kahi e koi ʻia ai ke kūpaʻa haʻalulu a me ka pale corrosion i ka manawa like.
