Dacromet Hexagonal Bolts | ʻIke ʻenehana 

1. Hoʻolauna

ʻO nā bolts hexagonal, i ʻike mau ʻia ʻo hex bolts, ʻo ia kekahi o nā mea hoʻopaʻa hoʻohana nui loa i ka ʻenekinia a me ke kūkulu ʻana. Ke hoʻonui ʻia me ka ʻenehana uhi Dacromet, hāʻawi kēia mau bolts i ke kūpaʻa corrosion kūʻokoʻa, ka pono mechanical, a me ka hilinaʻi lōʻihi a hiki i nā wahi ʻoi loa. Hāʻawi kēia ʻatikala i kahi kikoʻī kikoʻī o nā bolts hexagonal Dacromet, e uhi ana i kā lākou haku mele ʻana, nā mea maikaʻi, ke kaʻina hana, nā kikoʻī ʻenehana, a me nā noi ʻoihana.

ʻO Dacromet kahi ʻōnaehana pale zinc-flake proprietary i kūkulu mua ʻia no ka ʻoihana kaʻa. Aia ia me ka zinc a me ka alumini flakes i hoʻopaʻa ʻia e kahi matrix chromate inorganic. ʻAʻole like me ka electroplating maʻamau a i ʻole ka wela-dip galvanizing, ʻo ke kaʻina Dacromet he non-electrolytic, ka hopena i kahi ʻāpana pale lahilahi akā ʻoi aku ka maikaʻi ʻaʻole e hoʻoulu i ka hydrogen embrittlement-he pono koʻikoʻi no nā mea hoʻopaʻa ikaika kiʻekiʻe.

He aha ka Dacromet Coating?

ʻO Dacromet (i kapa ʻia ʻo ka zinc-flake coating) he mea hoʻoheheʻe wai, hoʻoheheʻe inorganic i hana ʻia mai ka pauka zinc, ka pauka alumini, a me nā mea hoʻopili chromate. Hoʻohana ʻia ma ke kaʻina hana dip-spin a i ʻole ka hoʻoheheʻe ʻana i ukali ʻia e ka mālama ʻana i ka wela kiʻekiʻe (ma kahi o 300°C), ua hana ʻia ka uhi i kahi pale multi-layered e hāʻawi ai i ka pale cathodic, pale pale, a me nā ʻano hoʻōla ponoʻī.

ʻO ka mānoanoa kiʻiʻoniʻoni maloʻo maʻamau mai 4 a 12 micrometers, ʻoi aku ka lahilahi ma mua o ka galvanizing wela wela (50-80 μm). ʻOiai ʻo kona ʻano lahilahi, ʻoi aku ka maʻamau o nā ʻili i uhi ʻia ʻo Dacromet ma mua o 1,000 mau hola o ka hoʻāʻo ʻana i ka paʻakai paʻakai me ka ʻike ʻole ʻia o ka ʻulaʻula.

2. Nā Pōmaikaʻi Nui o Dacromet Hex Bolts

Hāʻawi nā bolts hexagonal Dacromet i kahi hui kūʻokoʻa o nā waiwai i ʻoi aku ka maikaʻi ma mua o nā ʻano lapaʻau maʻamau.

• ʻOi aku ka pale ʻino ʻana: ʻOi aku ka hana paʻakai ma mua o 1,000–1,200 hola (ISO 9227 / ASTM B117), ma kahi o 7-10 mau manawa ʻoi aku ka maikaʻi ma mua o ka electro-galvanizing maʻamau.
• ʻAʻohe hoʻoheheʻe hydrogen: ʻO ke kaʻina hana non-electrolytic e hoʻopau i ka hydrogen absorption, e hoʻolilo iā Dacromet i mea kūpono no nā bolts kiʻekiʻe-tensile (Grade 8.8, 10.9, 12.9 a me ASTM A490).
• Paʻa-Mahana Kiʻekiʻe: ʻO ka mahana lawelawe hoʻomau a hiki i 300 ° C me ka hoʻohaʻahaʻa ʻole ʻana o ke kiʻi pale-ʻoi aku ka maikaʻi ma mua o nā uhi zinc maʻamau.
• ʻOi aku ka maikaʻi o ka Thread Fit & Dimensional Stability: Mālama ka ʻili lahilahi i ka geometry milo a hiki i ka hui ʻana me nā nati maʻamau.
• Hiki ke pena a me ka hoʻopaʻa hou ʻana: ʻO ka hoʻopili ikaika ʻana i nā topcoats organik e hiki ai ke hoʻopau aesthetic a i ʻole hana.
• Pilikino Bimetallic: Hana maikaʻi i ka pilina me ka alumini a me nā metala like ʻole, e hōʻemi ana i ka pōʻino galvanic.

3. Hana Hana

ʻO ke kaʻina hana uhi ʻo Dacromet no nā bolts hexagonal he kaʻina i mālama pono ʻia e hōʻoia i ka uhi like ʻole a me ka hana kiʻekiʻe.

1. Hoʻomākaukau ʻili: Hoʻomaʻemaʻe maikaʻi ʻia nā bolts a hoʻomaʻemaʻe ʻia no ka wehe ʻana i nā aila, oxides, a me nā mea haumia. ʻAʻole koi ʻia ka pickling acid, e hōʻemi hou ana i ka pilikia hydrogen.
2. Hoʻohana ʻia ʻo Dip-Spin: Hoʻokomo ʻia nā ʻāpana i loko o ka wai hoʻokuʻu ʻia ʻo Dacromet a laila wili i ka wikiwiki i hoʻopaʻa ʻia e hoʻokō i ka mānoanoa kiʻiʻoniʻoni like ʻole a wehe i ka uhi ʻoi aku.
3. Ho'ola mua a ho'ola hope: ʻO ka haʻahaʻa haʻahaʻa pre-bake e hoʻoheheʻe i ka wai, a ukali ʻia e ka sintering wela kiʻekiʻe (~ 300 ° C) e hoʻohui i nā ʻāpana zinc-aluminum i loko o kahi uhi paʻa paʻa.
4. Nānā maikaʻi: Hana ʻia ka mānoanoa o ka uhi ʻana, adhesion (cross-cut test), hiʻohiʻona, a me ka paʻakai paʻakai sampling e hōʻoiaʻiʻo i ka paʻa ʻana o ka pūʻulu.

4. Nā kikoʻī kikoʻī a me nā kūlana

Hana ʻia nā bolts hexagonal Dacromet i kahi ākea o nā kūlana honua a loaʻa i nā papa waiwai he nui.

5. Noi Hana Hana

Mahalo i kā lākou hui pū ʻana o ka ikaika a me ka pale ʻana i ka corrosion, ua kuhikuhi ʻia nā bolts hexagonal Dacromet ma nā ʻāpana koi nui:

6. Ka hopena

ʻO Dacromet hexagonal bolts e hōʻike ana i kahi mea hoʻopaʻa paʻa kiʻekiʻe e hoʻopaʻa ai i ka ʻokoʻa ma waena o nā pale zinc maʻamau a me nā mea ʻoi aku ka nui o ke kumukūʻai e like me ke kila kila a i ʻole nā ​​pūnaewele huila kūikawā. Hāʻawi kā lākou ʻenehana kiʻiʻoniʻoni lahilahi i ka pale corrosion koʻikoʻi, hoʻopau i nā hopohopo embrittlement hydrogen, mālama i ka hoʻomanawanui kikoʻī kikoʻī, a kūpaʻa i nā wela kiʻekiʻe - nā ʻano mea e pono ai i ka hana ʻenekinia hou.

Ke hoʻomau nei nā ʻoihana i ke ola lawelawe ʻoi aku ka lōʻihi, ka hoʻemi ʻana i ka mālama ʻana, a me ka hilinaʻi kiʻekiʻe ma lalo o nā kūlana kūlohelohe koʻikoʻi, ua manaʻo ʻia ka hoʻopaʻa ʻia ʻana o nā mea hoʻopili ʻia ʻo Dacromet. Ma ke koho ʻana i ka papa kūpono, ka nui, a me ka ʻōlelo kikoʻī, hiki i nā mea hoʻolālā a me nā ʻoihana kūʻai ke hoʻokō i ka maikaʻi ʻenehana a me ka hana kūpono.

No nā ʻōlelo aʻoaʻo kikoʻī o ka papahana a i ʻole nā ​​pepa ʻikepili ʻenehana, e nīnau i nā mea hoʻolako paʻa kūpono a me nā loea uhi.
