Ke koho ʻana i ke kila kuʻehiʻe kūpono no ka hana ʻana i nā kemika

Ma ka ʻoihana hana kemika, ʻoi aku ka maikaʻi o ke koho ʻana i nā mea waiwai ma mua o ka hana - he mea ia o ka palekana, ka lōʻihi, a me ke kumukūʻai. Pono nā mea hana i hoʻohana ʻia ma kēia ʻāpananā kemika hoʻopaʻapaʻa, nā wela kiʻekiʻe, nā kaomi kiʻekiʻe, anā kaiapuni corrosivei kēlā me kēia lā. ʻO kēia kahikila kohu ʻolehōʻike ʻia he koho kūʻokoʻa.

ʻAʻole naʻe i hana ʻia nā kila kila a pau. He mea koʻikoʻi ke koho ʻana i ka papa kūpono i ka loaʻa ʻana o ke ola lōʻihi o ka lawelawe ʻana, ka pale ʻana i ka hemahema o nā mea hana, a me ka hōʻoia ʻana i ka pono o ka hana. Ma kēia ʻatikala, ʻimi mākou i nā kumu koʻikoʻi no ke koho ʻana i ke kila kila i ka hana kemika, nā māka maʻamau, a me kā lākou mau pono kikoʻī. Lawe ʻia mai iā ʻoe esasaalloy, kou hoa hilinaʻi i nā mea kila kila no ka maikaʻi o ka ʻoihana.

No ke aha he mea nui ke kila kila ma ka hoʻoheheʻe ʻana i nā kemika

Hāʻawi ke kila kila i kahi hui kūikawā oka pale ʻana i ka corrosion, ka ikaika, ka pale wela, a me ka maʻemaʻe. Hoʻokumu ʻia kona ʻano chromium i kahi papa ʻokikene passive e pale ai i ka ʻili mai ka hoʻouka ʻana i ke kemika-ʻoiai i mua o nā ʻakika ikaika, alkalis, a me nā solvents.

ʻO nā pōmaikaʻi nui no nā kaiaola kemika:

  • Kūleʻa maikaʻi i ka lua a me ka ʻāʻī ʻana

  • ʻO nā waiwai mechanical ikaika ma nā wela kiʻekiʻe a haʻahaʻa

  • ʻO ka maʻalahi o ka hana a me ka wili

  • Ka mālama haʻahaʻa a me ke ola lawelawe lōʻihi

  • Hoʻohālikelike me nā ʻōnaehana maʻemaʻe a maʻemaʻe ma kahi (CIP).

At sasaalloy, Hāʻawi mākou i nā huahana kila kila kila i kūpono i nā kūlana honua a me nā koi kikoʻī o ka mea kūʻai aku.

Nā mea e noʻonoʻo ai i ke koho ʻana i ke kila kila

Ke koho ʻana i ke kila kila no nā noi kemika, pono e loiloi nā ʻenekini:

  • ʻO ka hoʻohui kemika o ka media kaʻina

  • Ka nui, ka mahana, a me ke kaomi

  • ʻAno ʻino (e laʻa, maʻamau, pitting, māwae koʻikoʻi)

  • Pono ka wiliwili a me ka hana ʻana

  • Hoʻokō hoʻoponopono a me ka maʻemaʻe

  • ʻO ke kumukūʻai a me ka loaʻa

Hiki ke alakaʻi i ka like ʻole ma waena o ke kaiapuni a me nā meahāʻule mua, nā pani kū'ai nui, a me nā pō'ino palekana.

Nā Papa Kūleʻa Kūleʻa maʻamau no ka Hoʻoponopono Kemika

1. 304 Ke kila kila

  • Huina: 18% chromium, 8% nikela

  • Nā pono: Ke kū'ē i ka corrosion maikaʻi, waiwai

  • Nā palena: ʻAʻole kūpono no nā kaiapuni piha i ka chloride

  • Nā noi: Nā pahu hoʻopaʻa, nā paipu, nā kākoʻo kūkulu

Hoʻohana nui ʻia ʻo 304 no nā lako kemika maʻamau, ʻoi aku ma kahiʻakika māliea i ʻole nā kaiapuni non-chloride.

2. 316 / 316L kila kila

  • Huina: 16% chromium, 10% nikela, 2% molybdenum

  • Nā pono: Hoʻomaikaʻi i ke kūʻē ʻana i nā chloride a me nā kaiapuni waikawa

  • Nā noi: Nā mea hoʻoheheʻe, nā mea hoʻololi wela, nā evaporators, nā kiwi

Ua loaʻa iā 316Lmaʻiʻo kalapona haʻahaʻa, e hoʻomaikaʻi ai nonā noi weldedkahi e pilikia ai ka ʻinoʻino ma nā hono.

3. 317L kila kila

  • Huina: ʻOi aku ka molybdenum ma mua o 316L

  • Nā pono: Hoʻonui kū'ē ika lua chloride a me ka ʻinoʻino

  • Nā noi: ʻO ka pulupulu a me ka pepa bleaching, nā mea hoʻoheheʻe kemika, nā mea holoi

Ke hāʻule pōkole ʻo 316L i nā kaiapuni ʻino loa, hāʻawi ʻo 317L i kahi piʻi waiwai i ka pale.

4. 904L kila kila

  • Huina: Kiʻekiʻe ka nickel a me ka molybdenum maʻiʻo

  • Nā pono: Maikaʻi maka honua ʻakika ikaikame ka sulfuric, phosphoric, a me ka acetic acids

  • Nā noi: Nā mea hoʻololi wela, nā mea hana pickling, ka hana ʻana i ka waikawa

904L kū'ē i nā mea ho'ēmi a me ka oxidizing a he kūpono loa iapāpaʻi hoʻopaʻapaʻai nā wela kiʻekiʻe.

5. Nā kila ʻili ʻole Duplex (e laʻa, 2205, 2507)

  • Huina: Hoʻolālā austenitic-ferritic kaulike

  • Nā pono: Ka ikaika kiʻekiʻe, ke kū'ē maikaʻi ihoʻohāhā ʻinoʻino

  • Nā noi: Nā moku kaomi, nā mea hoʻololi wela, ka hana ʻana i waho

Hoʻohui ʻia nā mea kila ʻole Duplex i nā waiwai maikaʻi loa o nā austenitic a me nā kila ferritic, e hoʻolilo iā lākou i mea kūpono no nā noi kiʻekiʻe, chloride-waiwai.

6. Huina 20 (UNS N08020)

  • Nā pono: Hoʻolālā kūikawā nopale ʻana i ka ʻakika sulfuric

  • Nā noi: Nā pahu hoʻopaʻa ʻakika, nā mea hoʻomaʻamaʻa pickling, ka lawe kemika

Hāʻawi ʻo Alloy 20 i ka pale maikaʻi loa manā hana ʻakika a me ka chloride, ʻoi aku ka maikaʻi ma mua o 316 a me 904L i nā kaiapuni sulfuric.

Nā noi ma ka ʻoihana Kimia

Hoʻohana ʻia ke kila kila ma kahi kokoke i kēlā me kēia pae o ka hana kemika, me:

  • Nā pahu waihona a me nā ipu kaomi

  • Huihui a me na keena pane

  • Nā mea hoʻololi wela a me nā condenser

  • Pūnaehana paipu a me nā kiwikā

  • Nā kolamu distillation a me nā scrubbers

Mahalo i kona ʻano maʻemaʻe a me ke ʻano non-reactive, kūpono hoʻi ke kila stainless nolāʻau lapaʻauahana kemika-meaʻai.

Nā Pōmaikaʻi o ke Koho ʻana i ka Papa Pono

ʻO ke koho ʻana i ka papa kila kuhiliʻole pololei e hōʻoia:

  • Hoʻemi ʻia ka manawa hoʻohaʻahaʻa ma muli o ka ʻino a i ʻole ka hiki ʻole

  • E emi iho na koina malama

  • ʻOi aku ke ola o nā mea hana

  • Hoʻonui i ka palekana a me ka hoʻokō

  • ʻOi aku ka maikaʻi o ka hoʻihoʻi ʻana i ke kālā

At sasaalloy, Ke hana pū nei kā mākou hui ʻenehana me nā mea kūʻai aku e ʻike i ke kumu kūʻai ʻoi aku ka maikaʻi o ka hoʻoheheʻe ʻana ma muli o nā kūlana hana maoli-ʻaʻole wale nā waiwai datasheet.

Ka hopena

I ka ʻoihana hoʻoponopono kemika, ʻo ke koho ʻana i nā mea waiwai he hoʻoholo hoʻoholo e pili pono anaka hana, ka palekana, a me ka waiwai. Me kona kū'ē kū'ē i ka corrosion, kūpaʻa wela, a me nā waiwai mechanical,ʻo ke kila kila he mea pōhaku kihino nā kaiapuni kemika koi.

Inā ʻoe e pili ana i nā waikawa, nā chlorides, ka wela kiʻekiʻe, a i ʻole ke kaomi.sasaalloyhāʻawi i ka piha piha o nā māka kila kila i hoʻolālā ʻia no ka hana maikaʻi loa. Mai ka 304 a me ka 316L a hiki i ka 904L a me ka duplex alloys,sasaalloyua kūpaʻa ʻo ia i ka hāʻawi ʻana i nā mea hana i kahi mea nui loa-i loko o kāu kaʻina hana.
