Kodi caustic soda "yoyenga yoyenerera" ili bwanji?

Custic soda, yodziwika ngati sodium hydroxide (Naoh), imatchedwa lye, caustic alkali, kapena sodium hydrate. Zimabwera m'mitundu iwiri yayikulu: yolimba ndi yamadzimadzi. Soda yolimba yolimba ndi yoyera, yoyera, yomwe imangokhala mu flake kapena mawonekedwe a glanular. Madzi a caustic amadzi ndi njira yothetsera matenda a Naoh.

Souaustic Soda ndi mankhwala ofunikira mankhwala omwe amagwiritsidwa ntchito kwambiri pakupanga mankhwala, zamkati ndi kupanga mapepala, zopangidwa ndi ma sopo.

1. Kuyambitsa kwa caustic koloko

1.1 lingaliro la caustic soda

Souaustic soda ili ndi formula Naoh. Amadziwika ndi:
1. Dongosolo lamphamvu: Naoh amasungunuka kwathunthu kukhala sodium ndi hydroxide ma ion m'madzi, kuwonetsa kukula kwamphamvu komanso korona.
2. Kusungunuka kwakukulu m'madzi: Imasungunuka mosavuta m'madzi ndi kutulutsidwa kwakukulu, ndikupanga yankho la alkaline. Amasungunuka ku Mounol ndi glycerin.
3.
4. Hygroscopicity: Naoh haoh ndi hygroscopic ndipo, ikawonetsedwa ndi mpweya, imatenga chinyezi mpaka isungunuke kwathunthu mu yankho lamadzimadzi. Madzi a caustic soda alibe nyumbayi.

1.2 Gulu la caustic soda
• Mwa mawonekedwe:
• Soda yolimba ya caustic: Flake caustic soda, granular caustic soda, ndi ng'oma yolimba caustic soda.
• Madzi a caustic soda: zozungulira zofanana ndi 30%, 32%, 42%, 45%, ndi 50% ndi 50% kukhala yofananira kwambiri pamsika.
• Machitidwe pamsika:
• Maituwa amadzimadzi a causbo a 80% yokwanira.
• Soda yolimba ya causdoe, makamaka flake caustic soda, imapanga pafupifupi 14%.

1.3 Mapulogalamu a caustic soda
1. Metallirgy: Amatembenuza zigawo zothandiza za ores mu sodium mchere, kulola kuchotsedwa kwa zosakanizidwa.
2. Zojambula ndi zojambula: zogwiritsidwa ntchito ngati wothandizila, wothandizila, komanso womugwira kuti apititsetse mawonekedwe a nsalu ndi kuyamwa kwa utoto.
3. Makampani azachipatala: Zopangira kiyi yophika popanga polycaborbote, ma polintralgent, epoxy amayendera, ma phosphary, ndi mchere wa sodium.
4. Pulp ndi Pepala: Chotsani Lignin ndi zodetsa zina kuchokera ku zamkati zamkati, kukonza pepala.
5. Zoyala ndi sopo: ndizofunikira mu sopo, chotchinga, komanso zodzikongoletsera.
6. Chitetezo cha chilengedwe: Sinthani madzi acidic acidic ndikuchotsa ma iyoni a chitsulo.

1.4 Kusunga, kusungirako, ndi mayendedwe
• Kusunga: kulembedwa ngati kalasi 8 yotsika mtengo pansi pa gb 13690-92 ndikuyenera kunyamula "zakuthambo" pa GB190-2009.
• Kuyendetsa:
• Madzi a caustic amadzi: kunyamulidwa mu akanki a kaboni; Mafudwe apamwamba kwambiri kapena> 45%, amafunikira nickel alloy a chitsulo.
• Soda yolimba ya caustic: yomwe imadzaza m'matumba a 25kg katatu kapena ng'oma.

2. Njira zopanga mafakitale

Souaustic soda imapangidwa kudzera m'njira ziwiri:
1. Njira Yopatsirana: Imaphatikizapo kuyanjasula sodium carbonate (Na₂co₃) ndi mkaka wa laimu (O) ₂) kupanga sodium hydroxide.
2. Njira ya Electroly: Electrolysis ya sodium chloride (nacl) Solutions (NACL) yokolola soda, yokhala ndi mpweya wa chlorine (H₂) monga mankhwala.
• Ion SEMBED PEMBRAne njira ndi njira yodziwika bwino electrolytic.

Kupanga Kupanga:
• 1 Mani a Naoh amatulutsa matani 0,886 a chlorine gasi ndi matani 0,025 a mpweya wa hydrogen.

Souaustic soda ndi njira yovuta kwambiri yothandizira mafakitale ndi ntchito yosiyanasiyana ya mafakitale angapo ndikuchita moyenera pamachitidwe osiyanasiyana.
