1. Isingeniso Sawa Soda, esaziwa ngesayensi njengeSodium Hydroxide (Naoh), i-alkali eqinile enokulungiswa okuqinile. Inamafomu amabili: aqinile noketshezi. I-CAUCIC Soda eqinile imhlophe futhi inama-flase, ama-granules, njll; I-Liquid Couustic Soda iwuketshezi olungenamibala futhi olusobala. Kuyancibilika kalula emanzini ukwakha ikhambi le-alkaline, futhi futhi liyahlanganiswa futhi liwohloka lapho libamba i-carbon dioxide. I-Caustic Soda iyinto esetshenziswayo yamakhemikhali eluhlaza okwesisekelo, futhi ingenye ye-alkalis emibili ku- "ama-acid amathathu kanye nama-alkalis amabili" kanye ne-soda ash. I-Caustic Soda inezinhlobonhlobo zokusetshenziswa, ikakhulukazi ezisetshenziswa e-alumina, i-pulp, odayi, imicu yamakhemikhali, ukucwilisa indwangu, ukuhlanzwa kwemikhiqizo yamalahle, nokuhlanzwa kwemishini yokudla, ukucubungula imishini Imboni, imboni yamakhemikhali, njll. Ngokwamafomu ahlukene, i-caustic soda ingahlukaniswa ibe yi-caustic soda ye-caustic ne-caustic soda eqinile. I-Liquid Couustic Soda ibizwa ngokuthi yi-ketshezi ye-caustic soda, okuvame ukuba yi-ketshezi engenabala futhi esobala. Ngokusho kwengxenyana enkulu yeSodium Hydroxide, i-Liquid Couustic Soda ingahlukaniswa ngo-30% u-Caustic Soda, ama-42% i-caustic soda, ama-45% i-caustic soda, ama-48% ama-caustic soda, ama-49% ama-caustic Soda, 50% i-caustic soda, njll. I-Soda no-50% i-caustic soda amamodeli ajwayelekile. I-Solid Couustic Soda ibizwa ngokuthi yi-soda eqinile ye-caustic, kufaka phakathi i-flake caustic soda kanye ne-granular caustic soda. I-Flake Couustic Soda isetshenziswa ikakhulukazi eChina. Ngokusho kwengxenyana enkulu yeSodium Hydroxide, i-soda eqinile ye-caustic ingahlukaniswa ku-73% Soda Soda, i-95% Soda Soda, 99% Soda Soda, 99.5% CAUCUCIC Soda, njll. Yikuphi i-99% flake caustic soda imodeli ejwayelekile.
2. Inqubo yokukhiqiza Inqubo yokukhiqiza ye-Caustic Soda ifaka indlela yokuqapha kanye nendlela ye-electrolysis. Indlela ye-Causticing yindlela ye-Soda ethola indlela, futhi indlela ye-elecporclys ingahlukaniswa nge-memury indlela, indlela ye-diaphragm, nendlela yokushintshana nge-ion. Indlela ye-Ion Membrane Exchange iyinqubo yokukhiqiza ejwayelekile emhlabeni njengamanje, futhi ama-99% e-caustic soda ezweni lami amukela le nqubo yokukhiqiza. I-ION Exchange Memorle Selectrolys yindlela yokuthola i-Caustic Soda ne-Chlorine ngokusebenzisa i-membrane yokushintshana okuzinzile yamakhemikhali ye-gempluorosulfonic acid. I-Ion Exchange Membrane inokuhlonza okukhethekile okukhethiwe, okuvumela kuphela amazwe okudlula futhi avimbe ama-anions namagesi kusuka ekudlule. Ngakho-ke, ngemuva kwe-electrolysis, kuphela i-anode electrodete na + kanti u-h + u-electrorte cl-, oh kanye ne-chlorine ekhiqizwa nge-electrolysis - ngaleyo ndlela kugwemeke ingozi yokuqhuma okubangelwa ukuxutshwa okubangelwa ukuxuba La magesi amabili, futhi futhi agwema ukukhiqizwa kokungcola okuthinta ubumsulwa be-caustic soda. Inqubo yokukhiqiza ye-Ion Membrane Electrolysis ihlukaniswe ngezinyathelo eziyisithupha: ukulungiswa kabusha, ukucwengwa kwe-brine, i-electrogesis, i-chlorine kanye nokwelashwa kwe-hykali, nokukhiqizwa okuqinile kwe-alkali. Ifomula yayo yamakhemikhali: 2nacl + 2h2o = 2naoh + 2h2 ↑ + CL2 ↑
3 Kuthatha ugesi ka-2300-2400 kWh no-1.4-1.6 amathani kasawoti aluhlaza ukuze ukhiqize ithoni elilodwa le-caustic soda, okuthi i-60% kanye ne-20% yezindleko zokukhiqiza ze-caustic soda ngokulandelana. Iningi lamabhizinisi we-chlor-alkali alwakha izitshalo zawo zamandla ukunciphisa izindleko, ngakho-ke amanani entengo yamalahle anomthelela othile ezindlekweni ze-caustic soda. Sekukonke, umkhuba wentengo kagesi wezimboni kanye nosawoti ovuthiwe ezweni lami uzinzile, ngakho-ke uhla lokuguquguquka lwe-caustic soda ohlangothini lwezindleko alukho. Njengento ebalulekile ebalulekile eyisisekelo ebonakalayo, i-caustic soda inezinhlobonhlobo zezinhlelo zokusebenza ezansi, ikakhulukazi kufaka phakathi i-alumina, ukuphrinta nokudaya, imboni yamakhemikhali, imboni yamakhemikhali kanye nezinye izinkambu. Phakathi kwazo, i-alumina ngumkhakha omkhulu wabathengi we-caustic soda, ukubalwa kwemali ngaphezu kwe-30% yemakethe yokusebenzisa i-caustic soda; Ukuphrinta nokudaya, ukusetshenziswa kwezimboni zamakhemikhali amakhemikhali kubalwa ngo-12,6%; Imboni yamakhemikhali, ukusetshenziswa kubangelwa cishe ngo-12%; Izimboni ezisele zihlakazekile, zibalwa isikhathi esingaphansi kwe-10%.
