1. Hoʻolauna

I ka hana ʻenehana hou a me ka ʻenehana kūkulu hale, ʻo ka hilinaʻi o nā mea paʻa e hoʻoholo pololei i ka hana palekana a me ke ola lawelawe o nā huahana a me nā hale. Hoʻohana nui ʻia nā bolts hex Countersunk ma waena o ka automotive, transit rail transit, machinery, building wall walls, home appliances, a me nā ʻoihana uila ma muli o ko lākou hiki ke noho paʻa me ka papa hana, hiʻohiʻona nani, a me ka hāʻawi ʻana i ka ukana. Eia nō naʻe, paʻakikī pinepine nā bolts electro-galvanized a i ʻole hot-dip galvanized e mālama pono i ka anti-corrosion a me ka hiki ke pale i ka ʻōpala i nā wahi humid, paʻakai-paʻakai, acidic, a i ʻole ka alkaline, e alakaʻi ana i nā pilikia e like me ka ʻōpala, ka uhi ʻana i ka delamination, hoʻemi ʻia ka ikaika clamping, a me ka haki.

ʻO kahi alakaʻi piha i ka Dacromet Countersunk Hex Socket Bolts

ʻO ka puka ʻana o Dacromet (i ʻike ʻia ʻo ka zinc-aluminum flake coating) e hāʻawi i kahi hopena kūpono i kēia pilikia. Hoʻohui pū ʻia nā bolts countersunk hex ʻo Dacromet me ka hoʻolālā ʻana i ka hoʻolālā ʻana i ka zinc-aluminum flake anti-corrosion. ʻAʻole wale lākou e hāʻawi i ka pale corrosion maikaʻi loa a me ka pale ʻana i ka ʻōpala akā mālama pū kekahi i ka ikaika mechanical kiʻekiʻe a me ka maʻalahi o ka hui. Hōʻike piha kēia ʻatikala i nā hiʻohiʻona ʻenehana a me ka waiwai noi o Dacromet countersunk hex socket bolts mai nā hiʻohiʻona o ka uhi ʻana i nā loina, ka hoʻolālā huahana, nā pono anti-corrosion, nā hiʻohiʻona noi, a me nā ʻōlelo aʻoaʻo koho.

2. ʻO ka nānā ʻana o ka ʻenehana ʻenehana Dacromet Coating

ʻO Dacromet, ka mea i kapa ʻia ʻo zinc-chromium coating a i ʻole zinc-aluminum coating, he ʻenehana lapaʻau non-electrolytic kiʻekiʻe. Hoʻohui ʻia nā ʻōpala zinc maikaʻi loa a me nā flakes alumini me ka chromate a me nā mea hoʻopaʻa kino ʻē aʻe e hana i kahi uhi wai. Hoʻopili like ʻia ka uhi ʻana i ka substrate metala ma ke kāʻei ʻana, kāpīpī ʻana, a i ʻole ka palu ʻana, a laila hoʻōla ʻia ma o ka sintering wela kiʻekiʻe e hana i kahi papa anti-corrosion composite. ʻO kēia ʻano ʻāpana he nui o ka zinc-aluminum flakes, i hoʻopaʻa ʻia e nā kiʻiʻoniʻoni chromate passivation, e hana i kahi pale "labyrinth effect" e pale pono ai i ke komo ʻana o ka wai, oxygen, a me nā media corrosive.

2.2 ʻO nā pono kumu o ka uhi ʻana o Dacromet

Ke hoʻohālikelike ʻia me nā kaʻina hana electro-galvanizing a me ka wela-dip galvanizing, hāʻawi ʻo Dacromet coating i nā pono nui i ka anti-corrosion a me ka pale ʻana i ka ʻōpala:

ʻOi aku ka maikaʻi o ka pale ʻana i ka paʻakai paʻakai: Hiki i nā pale Dacromet maʻamau ke kū i nā hola 500–1500 a ʻoi aʻe paha i nā hoʻāʻo paʻakai paʻakai, ʻoi aku ma mua o ka electro-galvanizing maʻamau (maʻamau 72-200 mau hola wale nō), e hoʻolōʻihi i ke ola lawelawe bolt i nā piʻi moana a me nā kaiapuni paʻakai de-icing alanui.
ʻAʻohe pilikia o ka hydrogen embrittlement: Hiki i ka electroplating kuʻuna ke hoʻokomo i nā ʻātoma hydrogen i loko o nā substrate kila ikaika loa, e hoʻoulu ai i ka haki ʻana o ka hydrogen embrittlement. ʻO Dacromet kahi kaʻina hana non-electrolytic e hoʻopau loa i kēia pilikia, e kūpono loa ia no nā bolts kiʻekiʻe.
ʻOi aku ka maikaʻi o ka wela kiʻekiʻe a me ka pale ʻana i ka wā: Paʻa mau ka uhi no ka hoʻohana lōʻihi ma kahi o 250 ° C a hiki ke kū i nā mahana kiʻekiʻe no nā manawa pōkole. Hōʻike pū ia i ke kūpaʻa ikaika i ka radiation ultraviolet a me nā pōʻai wela haʻahaʻa, e hōʻoiaʻiʻo ana i ka hana anti-corrosion a me ka pale-pale.
ʻO ka ho'ōla ponoʻī a me ka pale cathodic: Ke hoʻopōʻino ʻia ka uhi ʻana i ka wahi, hana ka zinc a me nā flakes alumini ma ke ʻano he anodes mōhai, e hāʻawi ana i ka pale electrochemical i ka substrate i hōʻike ʻia a hoʻonui hou aku i ka hiki ke pale aku i ka ʻino.

3. Nā hiʻohiʻona o ka Countersunk Hex Socket Bolts

ʻO nā bolts kumu hex Countersunk (ʻike pū ʻia ʻo nā ʻūhā kumu hex flat-head) kahi hoʻolālā conical a cylindrical countersunk head. Ma hope o ka hoʻokomo ʻana, e hoʻopololei loa ʻia ke poʻo i loko o ka countersink o ka mea hana, e loaʻa ai kahi ʻili maʻemaʻe ʻole. Aia ke kaʻa hex kūloko ma waenakonu o ke poʻo, e ʻae ana i ka hoʻopaʻa ʻana a me ka wehe ʻana me ke kī hex me ka hōʻemi ʻana i ka pilikia o ka paheʻe.

ʻO nā nui maʻamau mai M3 a M20 a me nā anawaena nui aʻe, me nā lōʻihi e hiki ke hoʻololi ʻia e like me nā koi. ʻO nā mea maʻamau he kila kalapona, ke kila kila, a i ʻole ke kila kila, i mālama ʻia me ka wela e hiki ai i nā papa waiwai e like me 8.8, 10.9, a i ʻole 12.9. Hāʻawi ka lāʻau ʻo Dacromet i ka pale anti-corrosion a me ka pale-pale me ka ʻole o ka hoʻopaʻapaʻa ʻana i ka pololei o ke kaula a i ʻole nā waiwai mechanical, e hana pono ai kēia mau bolts no nā noi e koi ana i ka palahalaha o ka ʻili a me ke kūpaʻa kiʻekiʻe.

4. Manaʻo koho a hoʻohana

No ka hoʻohana piha ʻana i nā pono anti-corrosion a me ka pale ʻana i ka ʻōpala o nā bolts countersunk hex socket bolts, ua ʻōlelo ʻia nā ʻōlelo aʻe i ke koho ʻana a me ka hoʻohana ʻana:

E koho i ka papa pani e like me ke kaiapuni lawelawe: Ua kūpono ka uhi ʻana o Dacromet maʻamau no nā wahi ʻoihana maʻamau; no ka paʻakai kiʻekiʻe a i ʻole ka pōʻino koʻikoʻi, ʻoi aku ka mānoanoa a i ʻole ka composite i hoʻopaʻa ʻia i ka uhi Dacromet e hōʻoia i ka hana anti-corrosion a me ka pale ʻana i ka ʻōpala.
Makemake i nā papa waiwai kiʻekiʻe: No ka mea, ʻaʻohe pilikia o ke kaʻina hana ʻo Dacromet, kūpono ia no ka papa waiwai 8.8 a ma luna o nā bolts ikaika kiʻekiʻe, e hōʻoia ana i ka ikaika pili a me nā koi anti-corrosion.
E hoʻomalu pono i ka torque hui: ʻOiai ua paʻa ka friction coefficient o ka uhi ʻana o Dacromet, ʻoi aku ka maikaʻi o ka hoʻoholo ʻana i ka torque paʻa kūpono ma o ka hoʻāʻo ʻana e pale aku i ka hoʻopaʻa ʻana a i ʻole ka hoʻopaʻa ʻana i hiki ke hoʻopilikia i ka hilinaʻi pili.
Hōʻalo i ka hoʻopili pololei ʻana me nā metala like ʻole: I nā kūlana e hiki mai ai ke ʻino galvanic, pono e hoʻohana ʻia nā mea holoi insulating a i ʻole nā hana hoʻokaʻawale i uhi ʻia i mea e pale hou aku ai i ka pono o ka ʻōnaehana anti-corrosion a me ka pale-rust.

5. Ka hopena

ʻO Dacromet countersunk hex socket bolts, me kā lākou zinc-aluminum flake composite coating technology, e hoʻokomo i ka mana anti-corrosion a me ka hiki ke pale i ka ʻōpala i nā mea hoʻopaʻa kuʻuna. Ke kū nei i ke ea moana haʻahaʻa a me ka paʻakai, ka hoʻoheheʻe ʻana o ke kinoea ʻenehana, a i ʻole ka ʻike ʻana i waho i ka lā a me ka ua, pale lākou i kēlā me kēia pili koʻikoʻi me ka hana paʻa a hilinaʻi. I ka wā e ʻimi nei i ke ola huahana lōʻihi, ka mālama haʻahaʻa, a me ka palekana kiʻekiʻe, ʻo ke koho ʻana i nā bolts hex socket Dacromet countersunk ʻaʻole ia he ʻike wale i ka ʻenehana anti-corrosion kiʻekiʻe akā he kūpaʻa hoʻi i ka maikaʻi o ka ʻenekinia a me ka palekana hana.

Me ka hoʻomau mau ʻana i ka ʻenehana uhi a me ka hoʻonui ʻana i nā hiʻohiʻona noi, e hoʻomau ʻo Dacromet countersunk hex socket bolts e hōʻike i ko lākou waiwai hiki ʻole ke hoʻololi ʻia i nā kula hou aʻe a lilo i mea hoʻonā maikaʻi no ka anti-corrosion a me ka pale ʻana i ka ʻōpala i nā pilina paʻa ʻoihana hou.

Mamua. Aʻe.
