Sodium hydrosulfite 90%, yakagadzirira kutumira ~

Zvishandiso:
1. The use of sodium hydrosulfite is very wide, mainly including reduction dyeing, reduction cleaning, printing and decolorization in the textile industry, as well as bleaching of silk, wool, nylon and other fabrics. Sezvo sodium hydrosulfite haina simbi inorema, ruvara rwemucheka wakasarudzika rwakajeka uye zvisiri nyore kupera.

Njodzi
Zvinopisa:Sodium Dithionicite chinhu chekutanga-kirasi chinhu chinopisa kana chakanyorohwa maererano nenhau dzenyika. It will react violently when it comes into contact with water, producing flammable gases such as hydrogen sulfide and sulfur dioxide, and releasing a large amount of heat. Iyo yekugadzirisa equation is: 2na2s2oo4 + 2h2o + o2 = 4nahso3, uye zvigadzirwa zvichiramba zvichiita kuburitsa hydrogen sulfide uye sarufa dioxide. Sodium Dithionicite ine iyo yepakati valence mamiriro eSarufa, uye zvivakwa zvaro zvemakemikari hazvina kugadzikana. Inoratidza yakasimba kuderedza zvivakwa. When it encounters strong oxidizing acids, such as sulfuric acid, perchloric acid, nitric acid, phosphoric acid and other strong acids, the two will undergo a redox reaction, and the reaction is violent, releasing a large amount of heat and toxic substances. Yayo reaction equation is: 2na2s2o4 + 4hcl = 2h2s2o4 + 4nacl

Zvinosunganidzwa Zvinotyisa:Sodium Dithionicite ine chirevo chinongoitika che25 ℃. Due to its low ignition point, it is a first-class flammable solid (the ignition point is generally below 300℃, and the flash point of low melting point is below 100℃). Zviri nyore kupisa kana kufumurwa kupisa, moto, kupokana uye kukanganisa. Kumhanya kwekukurumidza kuri kukurumidza uye njodzi yemoto yakakwira. Iyo gasi hydrogen sullide gasi yakagadzirwa panguva yekushambadzira inogona zvakare kukonzera nzvimbo yakakura yekubatanidza, ichiwedzera njodzi yayo yemoto.

Kuputika:Sodium Dithionicite ndeye Chiedza chellow poday chinhu. Chinhu chePowdery chiri nyore kuumba musanganiswa unoputika mumhepo. Guruva rinoputika rinoitika kana achisangana neinobva moto. Musanganiswa weSodium Didionionite uye vazhinji veOldIdium, vakadai sevanhu, vane moyo munyoro, vanopararira, kana vanoparidza. Even in the presence of water, it explodes after a slight friction or impact, especially after thermal decomposition, the flammable gas generated after the reaction reaches the explosion limit, then its explosion hazard is greater.
