ʻO ka pahu kaʻa DIN603

Hoʻolālā kumu:

Mea kumu: ke kila kalapona maʻamau (e like me ke kila 45 #, 40Cr) a i ʻole ke kila kila, me kahi ʻāpana zinc e uhi ana i ka ʻili ma hope o ke galvanizing.

ʻAno milo: ʻo ka lola trapezoidal maʻamau (ʻano Tr) a i ʻole wili pōlele, hoʻohana nui ʻia ka hope i nā hiʻohiʻona kiʻekiʻe.

Kaʻina hana Galvanizing: hoʻokaʻawale ʻia i ka zinc electroplated (ka uhi lahilahi a me ka ʻaʻahu) a me ka zinc hot-dip (ka uhi mānoanoa, ke kūpaʻa corrosion ikaika).

2. Nā hiʻohiʻona o ke kaʻina hana galvanizing

ʻO ka hana pale ʻino:

ʻO ka pale anode kaumaha: ʻO ka papa zinc e hoʻoheheʻe ʻia, e hoʻopaneʻe ana i ka ʻino o ke kila substrate.

Paʻa kino: Hoʻokaʻawale kahi papa zinc nui i ka mahu wai, oxygen, a me ka substrate mai ka hoʻopili ʻana.

Hoʻohālikelike kaʻina hana:

ʻAno kaʻina hana Ka mānoanoa o ka uhi ʻana Kūʻē ʻino Nā hiʻohiʻona kūpono ke kumu kūʻai

Galvanized 5-20 μm no nā lako o loko maʻamau, me ka haʻahaʻa corrosion

He 50-150 μm ka wela wela, maikaʻi loa ma waho, kemika, a me ka moana.

3. Nā pōmaikaʻi kumu

Ke kū'ē i ka corrosion: He kūpono no ka humid, spray paʻakai, acidic a alkaline environment (e like me nā moku a me nā mea hana kemika).

Hoʻokele waiwai: ʻOi aku ka haʻahaʻa o ke kumu kūʻai o ka galvanizing ma mua o nā wili kila kila, a ua hoʻonui nui ʻia ke ola.

Ka mālama haʻahaʻa: ʻO nā mea ho'ōla pono'ī o ka papa zinc e ho'ēmi i ka pono no ka mālama pinepine.

Hiki ke hoʻohālikelike: Hiki ke hoʻohālikelike ʻia me nā ʻōnaehana hoʻoili like ʻole, e like me nā kaʻa stepper a me nā kaʻa servo.

4. Nā hiʻohiʻona noi

ʻO nā mīkini waho: nā mīkini hana, nā mea mahiʻai (i ʻike ʻia i ka wai ua a me nā kaiapuni lepo).

ʻEnekinia moku a me ka moana: ʻenehana hoʻokiʻekiʻe deck, control valve (kū kūʻē i ka ʻinoʻino paʻakai).

Mea hana kemika: ʻōnaehana hoʻoili ʻana i ka ipu hao, ʻenehana hoʻoponopono paipu (ka waikawa a me ka alkali kūpaʻa ʻana).

ʻOihana hana: nā puka a me nā puka makani, nā paepae hoʻokiʻekiʻe (nā kumu kūʻai haʻahaʻa e pale ai i ka rust).
