ʻO ka ʻōpala hao hao hao

Paipu kila galvanized ʻO ka ʻōpala ka mea nui no ka zinc soluble i loko o ka waikawa a hoʻoheheʻe ʻia i loko o ka alkali, no laila e kapa ʻia ʻo ia me ka metala kāne.ʻO Zinc i ka ea maloʻo ʻaʻohe loli.Ma ka ea haʻahaʻa, e hoʻopuka ka ʻili zinc i kahi kiʻiʻoniʻoni o ka zinc carbonate kumu.Loaʻa i ka sulfur dioxide, hydrogen sulfide a me ka lewa moana, ke kūpaʻa maikaʻi ʻole o ka zinc, ʻoi aku hoʻi i loko o ka lewa wela a me ka haʻahaʻa i loaʻa i nā waikawa organik, hiki ke maʻalahi ka hoʻopili ʻana i ka zinc.Zinc maʻamau electrode hiki o-0.76V, ke kila substrate, ka zinc uhi mea anodic uhi, i hoʻohana 'ia e pale i ka corrosion o ka hao a me ke kila, ka pono a me ka pono o kona mau mea pale o ka uhi mānoanoa pilina mea nui.

ʻO ka Zinc coating, passivation, staining or coating retaining light agent, hiki ke hoʻomaikaʻi nui i ka pale a me ka hoʻonaninani.ʻO Zinc oxide i ka lewa, ka ʻili o ka hoʻokumu ʻana o ke keʻokeʻo keʻokeʻo, he mea maʻamau kēia kūlana.Ma muli o kāu kāʻei ʻo ia ka wela wela a i ʻole electro-galvanized, hot dip galvanized, a laila ma muli o ke ʻano mānoanoa o ka zinc e hoʻohua ai i ka ʻōpala keʻokeʻo ʻaʻole pili i ka palapala hoʻopaʻa maʻamau, no ka mea lohi loa ka oxidation rate o ka zinc i ka lewa.ʻAʻole maʻalahi ka ʻōlelo ʻana i ka electro-galvanized.ʻAʻole ʻike i ka ʻōpala ʻaʻole e pili.I ka wa e makemake e hoola i ka galvanized kila e makaʻala i ole e waiho pulu a me ka wela ventilation ua loa oluolu e hoʻoheheʻe, kekahi o ka hooilo, a laila pili i ka lōʻihi.

ʻO nā koi ʻenehana Galvanized Steel Pipe

No ke kaʻina nānā ʻana i ka maikaʻi o ke kaʻina hana, ʻo ka mea nui loa, ʻo ia ka hana noi ʻana o ka paipu kila.
ʻO ka piko o ka puʻu wela wela e pili ana i ke ʻano o kahi mea metala i loaʻa ka hua, ke degere o ka piko o ka specimen i ke kila galvanized i hoʻoheheʻe mua ʻia he mea nui loa, no ka mea hiki iā ia ke hoʻāʻo i ka paipu kila galvanized e ke kaomi o waho i ka wā o ka hopena. , ina i ka ho'āʻo galvanized kila paipu puʻe koʻikoʻi wahi, hiki iā mākou ke kūpono i ka hoʻoikaika ʻana i ka paipu kila galvanized i ʻoi aku ka affordability e like me nā koi o nā mea kūʻai aku.
Inā hāʻule ka mana, pono e hoʻokaʻawale i waena o ka helu o luna a me lalo.ʻO ka helu o luna ka hāpana e hāʻawi i ka mana i hāʻule no ka manawa mua ma mua o ka hiki ʻana o ke koʻikoʻi kiʻekiʻe;ʻO ke koʻikoʻi liʻiliʻi ka palena haʻahaʻa i ka wā e haʻalele ai i ka hopena transient mua, ka pae hua.ʻO ka papa kuhikuhi o nā mea metala paʻakikī e kūʻē i nā mea paʻakikī e kuhikuhi i ka hiki o ka ʻili, i kapa ʻia ʻo ka paʻakikī.
Ma muli o nā ʻano hoʻāʻo a me ka laulā o ka paʻakikī hiki ke hoʻokaʻawale ʻia i Brinell hardness, Rockwell hardness, Vickers hardness, Shore hardness, micro-hardness a me ka paʻakikī kiʻekiʻe.Hoʻohana maʻamau no ka paipu Brinell, Rockwell, Vickers paʻakikī.
