Nūhou - Paipu kila Galvanized：Nui，ʻAno a me ke kumukūʻai--Royal Group

Paipu kila galvanizedHe paipu kila i hoʻopaʻa ʻia me ka uhi zinc wela a i ʻole electroplated. Hoʻonui ka galvanizing i ke kūpaʻa o ka paipu kila i ka pala a hoʻolōʻihi i kona ola lawelawe. He ākea nā hoʻohana o ka paipu galvanized. Ma waho aʻe o ka hoʻohana ʻia ʻana ma ke ʻano he paipu laina no nā wai haʻahaʻa e like me ka wai, ke kinoea, a me ka ʻaila, hoʻohana ʻia nō hoʻi ia i ka ʻoihana petroleum, ʻoi aku hoʻi no nā paipu luawai ʻaila a me nā pipelines ma nā kahua ʻaila ma waho; no nā mea hoʻomehana ʻaila, nā mea hoʻoluʻu condenser, a me ka hoʻoheheʻe lanahu a me nā mea hoʻololi ʻaila holoi i nā lako coking kemika; a no nā pou pier a me nā kiʻi kākoʻo i loko o nā tunnels mine.

He aha ka nui o nā paipu kila galvanized?

He aha nā ʻano o nā paipu kila galvanized?

ʻAno	Kumumanaʻo o ke Kaʻina Hana	Nā Hiʻohiʻona Koʻikoʻi	Ola lawelawe	Nā hiʻohiʻona noi
Paipu kila Galvanized i hoʻoheheʻe ʻia me ka wai wela	E hoʻoluʻu i ka paipu kila i loko o ka wai zinc heheʻe (ma kahi o 440-460 ℃); hana ʻia kahi uhi pale pālua ("papa hao zinc + papa zinc maʻemaʻe") ma luna o ka ʻili o ka paipu ma o ka hopena kemika ma waena o ka paipu a me ka zinc.	1. Papa zinc mānoanoa (maʻamau 50-100μm), hoʻopili ikaika, ʻaʻole maʻalahi e ʻili; 2. Kū'ē maika'i loa i ka palaho, kū'ē i ka waikawa, ka alkali a me nā wahi waho ko'iko'i; 3. ʻOi aku ke kumukūʻai o ke kaʻina hana, ʻano hina-hina me kahi ʻano ʻinoʻino iki.	15-30 mau makahiki	Nā papahana waho (e like me nā pou kukui alanui, nā pale), ka lako wai/hoʻokahe wai o ke kūlanakauhale, nā paipu kinai ahi, nā paipu kaomi kiʻekiʻe o ka ʻoihana, nā paipu kinoea.
Paipu kila galvanized electro	Hoʻokomo ʻia nā iona zinc ma luna o ka ʻili paipu kila ma o ka electrolysis e hana i kahi uhi zinc maʻemaʻe (ʻaʻohe papa alloy).	1. Papa zinc lahilahi (maʻamau 5-20μm), nāwaliwali ka hoʻopili ʻana, maʻalahi ke komo a me ka ʻili; 2. ʻO ke kūpaʻa maikaʻi ʻole i ka pala, kūpono wale nō no nā wahi maloʻo a ʻaʻole palaho i loko; 3. Ke kumukūʻai hana haʻahaʻa, ʻālohilohi a laumania ke ʻano.	2-5 mau makahiki	Nā paipu haʻahaʻa o loko (e like me ka lako wai no ka manawa pōkole, nā paipu hoʻonaninani no ka manawa pōkole), nā pale lako (ʻaʻohe ukana), nā ʻāpana hoʻonaninani o loko.

He aha ke kumukūʻai o nā paipu kila galvanized?

ʻAʻole paʻa ke kumukūʻai o ka paipu kila galvanized a loli nui ia ma muli o nā kumu like ʻole, no laila hiki ʻole ke hāʻawi i kahi kumukūʻai like.

I ke kūʻai ʻana, ua ʻōlelo ʻia e nīnau e pili ana i kāu mau koi kikoʻī (e like me ke anawaena, ka mānoanoa o ka paia (e like me SCH40/SCH80), a me ka nui o ke kauoha—ʻo nā kauoha nui o 100 mika a ʻoi aku paha e loaʻa pinepine ana he 5%-10% hoʻēmi) no ka loaʻa ʻana o nā kumukūʻai pololei a hou loa.
