Caustic Soda

Tsananguro Pfupi:

Caustic soda ndeye chena yakasimba ine yakasimba hygroscopicity. Inonyungudika uye kuyerera mushure mekunwa hunyoro. Inogona kutora mvura uye carbon dioxide mumhepo kuti ibudise sodium carbonate. Iyo brittle, inogadziriswa mumvura, doro, glycerin, asi haina insoluble muacetone. Hwakawanda hwekupisa hunoburitswa kana hwanyungudika. Mvura inoyerera inotsvedza uye alkaline. Iyo inokanganisa zvakanyanya uye inogona kupisa ganda nekuparadza iyo fibrous tishu. Kubata nealuminium patembiricha yakakwira kunogadzira hydrogen. Iyo inogona kudzikamisa neacids uye kugadzira akasiyana salts. Liquid sodium hydroxide (i.e.
Kugadzirira kwe caustic soda ndeye electrolytic kana kemikari. Makemikari nzira dzinosanganisira lime causticization kana ferrite.
Iko kushandiswa kwesaustic soda kunonyanya kushandiswa mukugadzira sipo, sipo, kugadzira papermaking; inoshandiswawo senge solvent yevaty madhayi uye isina insoluble nitrogen madhayi; zvakare inoshandiswa mukugadzira peturu, makemikari faibha, uye rayon; zvakare inoshandiswa mukurapa, senge kugadzirwa kwevhitamini C Mirira. Inogona zvakare kushandiswa mu organic synthesis uye petroleum maindasitiri uye yakashandiswa zvakananga sediccant.

Mhangura sulphate ibhuruu yekristaro granular, inosungunuka mumvura uye yakasanganiswa acetic acid. Mhinduro yacho inoratidzika seasina simba acidity. Ichave effloresces zvishoma nezvishoma mumhepo yakaoma, uye pamusoro payo ichave chena hupfu chinhu.

Mhangura sulfate icharasikirwa nemvura ina yekristaro painopisa kusvika 110 ° C, uye inozoshandurwa kuita chena Copper sulphate anhydrous iyo iri nyore kupinza mvura kana tembiricha iri pamusoro pe200 ° C.

1) Flotation reagent mumugodhi indasitiri; electroplating maindasitiri; reagent mukugadzirira dyestuffs intermediates; mordant mune värjäys; preservative huni etc.

2) Inoshandiswa zvakanyanya mune yekudyara indasitiri senge yekuwedzera yekuwedzera; Kugadziriswa kwekushomeka kwemhangura mumhuka; Kukura kunosimudzira kwekukodza nguruve uye huku dzehuku nezvimwe.

3) Inoshandiswa zvakanyanya mukurima sefetiraiza; fungicides; zvipembenene; kukura kunosimudzira kwekukodza nguruve uye huku dzehuku nezvimwe

Mhangura Sulphate inoshandiswa kuburitsa imwe mhangura, inoshandiswa zvakare seye machira mordant, mishonga yekuuraya zvipuka, fungicides, uye kurapwa kwemvura. Se mordant yekotoni nesirika; yaishandiswa kuburitsa girini nebhuruu pigment; inoshandiswa sechipembenene, bactericide yemvura, antiseptics yehuni, zvinokonzeresa tannage, electrocopper, bhatiri. kuveza zvichingodaro; inoshandiswa muindasitiri yekuchera uye sezvinhu zvakasvibirira zvemamwe makemikari.

1.Used mukugadzirwa kwepepa uye cellulose pulp.

2. Inoshandiswa kugadzirwa kwesipo, synthetic detergents, synthetic fatty acids.

3. Inoshandiswa sejira rinoshuvira mumiririri, yekumurova mumiririri uye sirika polish mumiriri mumachira kudhinda.

4. Inoshandiswa mukugadzira borax, sodium cyanide, formic acid nezvimwe muindastiri yemakemikari.

5. Inoita chinhu chakakosha pakugadzira makemikari mazhinji anobatsira (zvinopfuura makumi matatu kubva muzana).

6. Inorganic makemikari sependi, girazi uye ceramics uye zvinoshandiswa mukugadzira mafuta maseru uye zvipfeko zvakare zvakakosha kwazvo.

7. Mapepa, pulp uye cellulose maindasitiri ndivo vashandisi vakuru ve caustic soda.Dzimwe nzvimbo panokosha caustic ndeiyi: indasitiri yezvikafu, kurapwa kwemvura (kune flocculation yesimbi inorema uye acidity kudzora), sipo uye sipo yezvikamu, machira. chikamu (seyuniti yekuchenesa), zvicherwa zvemafuta (girisi uye mafuta anowedzera) uye synthesis yeyakagadzirwa fiber rayon

8. Zvinenge zvikamu zvina kubva muzana zveshuwa zvinogadzirwa zvinoshandiswa mukugadzirisa aruminiyamu kubva kune yayo ore bauxite.

9. Iyo yakasara yeacustic kugadzirwa (inopfuura 17%) ine zvakasiyana-siyana zvinoshandiswa, senge synthesis yemishonga yemakemikari, yerabhuru yekushandura zvakare uye iyo neutralization yeacids.
