ʻO Dacromet Flange Bolts: He Hoʻolauna piha i nā mea hoʻopaʻa hoʻopaʻa kiʻekiʻe. 

ʻO nā hiʻohiʻona nui o ka uhi ʻana o Dacromet ma nā Bolts

• ʻOi aku ka maikaʻi o ka corrosion resistance: ʻOi aku ma mua o 1,000 mau hola o ka hoʻāʻo ʻana i ka paʻakai paʻakai (ASTM B117 / ISO 9227) me ka ʻole o ka ʻulaʻula.
• Kiʻiʻoniʻoni lahilahi a ʻaʻahu: ʻO 4-8 μm wale nō ka mānoanoa, e mālama pono ana i ka ʻae ʻana o ke kaula o ka bolt.
• Kūleʻa wela kiʻekiʻe: Mālama i ka hana pale a hiki i ka 300 ° C lawelawe mau.
• Kūʻē kemika maikaʻi loa: Kū'ē i nā paʻakai alanui, nā wai kaʻa, nā ʻakika māmā, a me nā lewa ʻoihana.
• ʻO ke kuʻi ʻana: ʻO ka pilina torque-tension paʻa no ka hoʻopaʻa paʻa ʻana i ka bolt.
• ʻAno metala hina hina: ʻAʻahu like ʻole, hoʻopau matte hiki ke pena ʻia.

3. ʻO nā pono o Dacromet Flange Bolts

Hāʻawi ʻo Dacromet flange bolts i kahi hui kūʻokoʻa o nā pono mechanical a me ka pale-pale i mea e makemake ai lākou ma mua o nā bolts i uhi ʻia ma nā wahi koi.

Kūʻē kūʻē i ka ʻino a me ka hana kūʻē i ka Rust

Hoʻokumu ka ʻōnaehana zinc-aluminum flake multi-layered o Dacromet i kahi hopena pale a me kahi hopena anode mōhai. Hāʻawi kēia mīkini pālua 7 a 10 manawa ka pale ʻana i ka corrosion o nā pale electro-galvanized kuʻuna. Hiki i nā bolts flange Dacromet kiʻekiʻe ke hoʻokō ma mua o 1,200 mau hola o ka pale ʻana i ka paʻakai me ka ʻike ʻole ʻia o ka ʻulaʻula ʻulaʻula, e hōʻoiaʻiʻo ana i ka pale anti-rust no ka wā lōʻihi ma ke kahakai, kai, a i ʻole ka paʻakai paʻakai.

ʻAʻohe pilikia o ka hoʻoheheʻe ʻana o ka hydrogen

Hiki ke ma'alahi i ka embrittlement hydrogen ke hana 'ia e ka electroplating ma'amau. Hoʻopau ke kaʻina hana Dacromet i ka pickling acid a me ka electrolytic deposition, pale loa i ka hoʻokomo hydrogen. Hoʻolilo kēia iā Dacromet i ka uhi i makemake ʻia no nā bolts flange pili i ka hana koʻikoʻi a me ka palekana.

Mālama ʻia ka ʻili lahilahi i ke kūpono o ke kaula

Me ka mānoanoa maʻamau o 4-8 μm wale nō, ʻaʻole i hoʻololi nui ka uhi Dacromet i ke anawaena pitch o nā kaula bolt. ʻAe kēia i ka hoʻohana ʻana i nā nati maʻamau me ka ʻole o ka overtapping, ka mea i koi pinepine ʻia no nā uhi galvanized wela wela. ʻO ka hopena, ʻoi aku ka maikaʻi o ka hoʻopili ʻana i ke kaula, ʻoi aku ka paʻa o ka preload, a me ka maʻalahi o ka hui ʻana o nā bolts flange.

4. Hoʻohālikelike Hana ʻana o nā Kāpena Bolt

Hoʻohālikelike ka papa ma lalo nei iā Dacromet me nā uhi ʻokoʻa maʻamau i hoʻohana ʻia ma nā bolts:

Papa 1. Ka hana hoʻohālikelike o nā lāʻau lapaʻau maʻamau.

5. ʻO nā alakaʻi koho no ka Dacromet Flange Bolts

Ke kuhikuhi ʻana i nā bolts flange Dacromet no kahi papahana, e noʻonoʻo i kēia mau mea e hōʻoia i ka hana anti-corrosion maikaʻi loa a me ka hilinaʻi hui.

1.Corrosivity o ke kaiapuni: ʻO ka hōʻike ʻana i ke kahakai, kai, ʻoihana, a i ʻole ke alanui-paʻakai ka mea maʻamau e hōʻoia i ka pae B a i ʻole ke kiʻekiʻe o ka uhi Dacromet.

2.Bolt ikaika papa: No ka papa 10.9 a me ka 12.9 flange bolts, ʻōlelo ikaika ʻia ʻo Dacromet e hoʻopau i ka pilikia embrittlement hydrogen.

3. Temperature hoʻolaha: Loaʻa nā noi e pili ana i ka 250-300°C mai ke kūpaʻa wela o Dacromet.

4.Torque-tension koi: E wehewehe i kahi kapa lubricated (e laʻa, PLUS® a i ʻole DACROLUB®) ke koʻikoʻi ka mana preloading pololei.

5. Hoʻohālikelike me nā ʻāpana male: Hōʻike ʻo Dacromet i ka hoʻohālikelike bimetallic maikaʻi me nā ʻāpana alumini, e hōʻemi ana i ka pōʻino galvanic.

6. Ka hopena

Hōʻike nā bolts flange Dacromet i kahi hopena hoʻopaʻa paʻa kiʻekiʻe e kamaʻilio pū ana i ka pono hui mechanical a me ka pale ʻana i ka ʻili no ka wā lōʻihi. Ma ka hoʻohui ʻana i nā pono hoʻokaʻawale ukana o kahi poʻo flange me ka mea koʻikoʻi kuʻi-corrosion a kūʻokoʻa nā waiwai o ka zinc-aluminum flake coating, hāʻawi kēia mau bolts i ka lawelawe hilinaʻi i nā wahi ʻoi loa.

ʻO nā mea lawe nui no nā ʻenekinia a me nā loea kūʻai:

• Hāʻawi ʻo Dacromet i 7-10 mau manawa i ka pale ʻana i ka corrosion o ka electro-zinc plating maʻamau ʻoiai e waiho ʻia ana ka lahilahi e mālama ai i ke kūpono o ke kaula maʻamau.
• ʻO ke kaʻina hana non-electrolytic e hoʻopau loa i ka hoʻoheheʻe ʻana o ka hydrogen, e hana maikaʻi ai no nā bolts flange ikaika kiʻekiʻe.
• ʻO ke kūpaʻa wela kiʻekiʻe maikaʻi loa (a hiki i 300°C) a me ke kūpaʻa kemika e hoʻonui hou aku i nā hiki ke noi.
• ʻO ka hoʻolālā flange i hoʻohui ʻia e maʻalahi i ka hui ʻana a hoʻomaikaʻi i ka hana hui ma lalo o ka haʻalulu a me ka hoʻouka ʻana.

Inā hoʻohana ʻia i nā chassis kaʻa, nā turbine makani o waho, nā ʻoihana kahakai, a i ʻole nā ​​mea hana ʻoihana koʻikoʻi, hāʻawi ʻo Dacromet flange bolts i kahi ala i hōʻoia ʻia i ke ola lawelawe lōʻihi, hoʻemi ʻia ka mālama ʻana, a me ka palekana palekana. ʻO ka wehewehe ʻana i ka papa Dacromet kūpono a me ka hōʻoia ʻana i ka mana maikaʻi kūpono e hoʻonui i nā pono anti-rust a me nā anti-corrosion i hoʻolālā ʻia e kēia mau bolts holomua e hoʻopuka.
