1. He aha ka Hot-Dip Galvanizing?

ʻO ka galvanizing Hot-dip kahi hana i hōʻoia ʻia i nā mea paʻa kila - e like me nā kī hex, nā heleuma, nā nati flange, a me nā lāʻau kaula - hoʻokomo piha ʻia i loko o kahi ʻauʻau o ka zinc hehee ma kahi o 450 °C (842 °F). Hoʻopaʻa ka zinc metallurgically i ka ʻili kila, e hana ana i ka manoanoa, ka uhi ʻana i nā ʻāpana he nui (maʻamau. 45–85 µm) e hana ana ma ke ʻano he pale kino a he anode mōhai e kūʻē i ka ʻino.

ʻO nā pōmaikaʻi nui o nā mea hoʻopili HDG:

Ke ola lōʻihi: Ka lōʻihi o ke ola lawelawe: 20-70 mau makahiki ma ka hapanui o nā kaiapuni waho

Papa zinc mānoanoa a paʻa ʻO ka papa zinc mānoanoa a paʻa e kū i ka pōʻino mechanical

Hana maikaʻi loa ʻO ka hana maikaʻi loa ma ke kai, ke kūkulu ʻana, a me nā noi ʻoihana

Pale ʻālana ʻO ka pale ʻana - ua ʻino ka zinc ma mua o ka hana ʻana o ke kila

Kūʻai-pono ʻO ka uku kūpono no nā bolts nui a me nā mea hoʻopaʻa hana

2. He aha ka Dacromet Coating?

ʻO Dacromet (i kākau pū ʻia ʻo Geomet a i ʻole Dacrotized) he uhi wai, chromate-free i haku ʻia me nā microscopic zinc a me nā ʻāpana alumini i hoʻokuʻu ʻia i loko o kahi mea hoʻopili inorganic. ʻO nā wili, nā kī, nā mīkini mīkini, nā wili paʻi ponoʻī, a ua uhi ʻia nā mea hoʻopaʻa pololei a hoʻōla ʻia ma 300 °C (572 °F). ʻO ke kiʻiʻoniʻoni ka hopena he lahilahi loa (8–12 µm) akā, hāʻawi i ke kūpaʻa ʻino - ʻoi aku ka nui 720 hola i loko o nā ho'āʻo hoʻoheheʻe paʻakai (ASTM B117).

ʻO nā pōmaikaʻi nui o nā mea paʻa i uhi ʻia ʻo Dacromet:

ʻO ka uhi ʻulaʻula ʻO ka uhi ʻana o Ultrathin - mālama i nā ʻae paʻa i nā wili a me nā bolts

ʻAʻohe pilikia o ka hoʻoheheʻe hydrogen ʻAʻohe pilikia o ka hoʻoheheʻe ʻia o ka hydrogen - palekana no nā bolts ikaika kiʻekiʻe (Papa 8.8, 10.9, 12.9)

Hana maikaʻi i nā paʻakai alanui Hana maikaʻi loa e kūʻē i nā paʻakai alanui - kūpono no nā mea paʻa kaʻa a me nā mīkini

Ka uhi like ʻole ʻO ka uhi like ʻole ma nā geometries paʻakikī: nā lua i hoʻopaʻa ʻia, nā mea hoʻopaʻa makapō, nā wili liʻiliʻi

Pili kaiapuni Aloha kaiapuni - Hoʻopili ʻo RoHS, ʻaʻohe chromium hexavalent

3. Hoʻohālikelike ʻaoʻao

Hōʻuluʻulu ka papa ma lalo nei i nā ʻokoʻa koʻikoʻi ma waena o ka galvanizing hot-dip a me ka uhi Dacromet no nā ʻano hoʻopaʻa maʻamau e like me nā bolts, screws, nuts, bolts heleuma, a me nā lāʻau kaula.

4. Ke koho ʻana i ka uhi kūpono no kāu noi Fastener

ʻO ka hoʻoholo ma waena o HDG a me Dacromet e pili ana i ʻekolu mau kumu: ke kaiapuni noi, ka nui a me ka pae, a me nā koi hoʻomanawanui dimensional.

E koho i ka Galvanizing Hot-Dip inā:

E hoʻohana ʻia nā mea paʻa i waho, moana, a i ʻole nā ​​ʻoihana ʻoihana kaumaha

Pono ka pale corrosion no ka wā lōʻihi (20+ makahiki) me ka ʻole e hoʻihoʻi hou

Loaʻa nā huahana i nā bolt kūkulu nui (M16–M72), nā heleuma, nā nati hex, a i ʻole nā mea holoi palahalaha.

ʻO ka lōʻihi o ka mīkini ma lalo o ka abrasion a i ʻole ka hopena ka mea nui

E koho iā Dacromet Coating inā:

He 10.9, 12.9, a i ʻole ke kiʻekiʻe aʻe - pono e pale ʻia ka hoʻoheheʻe ʻana o ka hydrogen.

He mea koʻikoʻi ka hoʻomanawanui ʻana o ka nui (e laʻa.

ʻO ka hoʻohana hope ʻana e pili ana i ka ʻike ʻana i nā paʻakai de-icing alanui, nā kemika, a i ʻole ka haʻalulu kiʻekiʻe.

Pono ka hoʻokō ʻana o RoHS / ELV (Automotive OEM, electronics assembly)

5.FUJINRUI: Kou Puna no ka Anti-Corrosion Fasteners

Hoʻokumu ʻo FUJINRUI Metal i nā mea hoʻopaʻa kū i ka corrosion no nā mākeke hoʻoili honua. Loaʻa i kā mākou hui huahana u'i wela wela, ʻO nā wili i uhi ʻia ʻo Dacromet, nā mea hoʻopaʻa kila kila, a nā kī heleuma i uhi ʻia i ka zinc-flake ma na nui mai M6 a i M72. Hana ʻia nā huahana āpau i ISO, DIN, ASTM, a me nā kūlana kikoʻī o ka mea kūʻai aku.

Inā makemake ʻoe i kahi ʻāpana liʻiliʻi o nā wili metric pololei a i ʻole ka nui-nui nā wili hana a me nā nati hex no nā papahana hoʻolālā, hāʻawi kā mākou hui i ke kākoʻo ʻenehana piha mai ke koho ʻana i nā mea ma o ka mālama ʻana i ka ʻili, ka nānā ʻana, a me ka hōʻiliʻili ʻana i waho.
