Caustic soda "yakanatswa" sei?

Caustic soda, yemakemikari anozivikanwa seSodium Hydroxide (Naoh), inowanzodaidzwa kuti Lane, Caustic Alkali, kana Sodium Hydrate. Iyo inouya mumhando mbiri huru: yakasimba uye yemvura. Solid Caustic soda ndeye chena, hafu-yakajeka crystalline chinhu, kazhinji mune flake kana fomu yekudonha. Liquid caustic soda ndiyo mhinduro yemhedzisiro yaNao.

Caustic soda ndiyo yakakosha yemakemikari yakasarudzika yakashandiswa zvakanyanya kugadzirwa, pulp uye pepa rekugadzira, metallurgy

1. Nhanganyaya kune caustic soda

1.1 Pfungwa yeCaustic soda

Caustic soda ine yemakemikari formula naoh. Inoratidzwa ne:
1. Zvakasimba Zvakasimba: NAHOH Kureba kweSodium uye Hydroxide ions mumvura, kuratidzira ruzivo rwakasimba uye zvakarongeka zvivakwa.
2. Solubility yakakwirira mumvura: Inopenya zviri nyore mumvura nekukweverwa kwakakura kwekupisa, kugadzira alkaline solution. Izvo zvinonyangadzawo kuEthanol neGlycerin.

4.. Liquid caustic soda haina chinhu ichi.

1.2 Kugadziriswa kweCaustic soda
• nechimiro chemuviri:
• Solid Caustic Soda: Flake Caustic Soda, Granular Caustic Soda, uye Drum-Yakavhurika Yakasimba Caustic Soda.
• Liquid caustic soda: Zvakajairika kutarisisa zvinosanganisira 30%, 32%, 42%, 45%, uye 50%, ne30% uye makumi matatu neshanu muzana uye makumi mashanu muzana.
• share yemusika:
• Liquid caustic soda account ye80% yekugadzirwa kwakazara.
• Solid Caustic soda, kunyanya flake caustic soda, inogadzira anenge 14%.

1.3 zvikumbiro zveCaustic soda
1. Metallurgy: Inoshandura zvinhu zvinobatsira zveOres muzvinyorwa zvekunyaradza sodium, ichibvumira kubviswa kwezvinhu zvisina kufanira.
2. TEXILE uye Dyeing: Inoshandiswa seyekunyorova mumiririri, muurayi mumiririri, uye unonhuwirira mumiririri kuti uvandudze chimiro chechibereko uye dhayi.
3. Indasitiri yemakemikari: Chinyorwa cheMakero Chinobira Mukugadzira Polycarbonate, SuperaButbent Polymers, epoxy inogara, phosphate, uye dzakasiyana sodium.

5. DZVANYA uye SOOPS: Zvakakosha muSipo, Destagent, uye kugadzirwa kweCosmetic.

1.4 Kutakura, kuchengetedza, uye kufambisa
• Kukatyamadzwa: Yakatemerwa sekirasi 8 colorives chinhu pasi peGB 13692 uye inofanira kutakura iyo "yezvinhu zvakashata" chiratidzo cheGB190-2009.
• Kufambisa:
• Liquid Caustic Soda: Inotakurwa muCarbon Steel Tankers; Yakanyanya-Kuchena kana> 45% Solitrention Solutions Inoda Nickel Alloy Steel Tankers.
• Solid Caustic Soda: kazhinji yakarongedzwa mu25kg katatu-layer mabhegi akavezwa kana zvigubhu.

2. Maindasitiri ekugadzira nzira

Caustic soda inonyanya kubudiswa kuburikidza nenzira mbiri:
1.
2. Electrolytic nzira: Electrolysis yeSodium Sodium chloride (NACL) mhinduro inopa soda, ine chlorine gasi (CLDROGEN GES (H₂) se-zvigadzirwa.
• Iyo Ion yekutsinhana membrane nzira ndiyo yakajairika elektrolytic maitiro.

Kugadzirwa ratio:
• 1 toni ye naoh inogadzira 0.886 matani eChlorine gasi uye 0.025 matani ehydrogen gasi.

Caustic soda ndeyemakesi akaomesesa emakemikari ane akawanda-ekutanga-kubva kuindashandirwi maindasitiri akawanda uye anoita basa rinokosha mune dzakasiyana siyana dzekugadzira maitiro.
