Hauv daim ntawv thov, qhov sib txawv ntawm granular caustic soda thiab flake caustic soda. Peb paub tias granular caustic soda thiab flake caustic soda yog ob qho tib si sodium hydroxide nyob rau hauv muaj pes tsawg leeg, qhov sib txawv yog tias ob qho tib si nyob rau hauv ntau hom, yog li muaj qee qhov sib txawv ntawm kev siv ntawm ob.
Granular alkali feem ntau yog siv los ua cov khoom siv tshuaj, yog ib qho tseem ceeb ntawm cov khoom siv raw, thiab muaj ntau yam kev siv. Kev lag luam tshuaj yog siv rau hauv kev tsim cov formic acid, oxalic acid, borax, phenol, sodium cyanide thiab xab npum, hluavtaws fatty acids, hluavtaws detergents, thiab lwm yam. Textile printing thiab dyeing kev lag luam yog siv paj rwb desizing tus neeg saib xyuas, hnyav rau scouring tus neeg saib xyuas, mercerizing tus neeg sawv cev, vat dye thiab Haichang xiav dye. Siv nyob rau hauv kev lag luam smelting los tsim aluminium hydroxide, alumina thiab hlau deg kho cov neeg ua haujlwm. Kev lag luam ntsuas yog siv los ua acid neutralizer, decolorizer thiab deodorizer. Adhesive kev lag luam yog siv los ua hmoov txhuv nplej siab gelatinizer thiab neutralizer. Tsis tas li ntawd, nws yog dav siv hauv enamel, tshuaj, tshuaj pleev ib ce, tawv, xim, tshuaj tua kab, iav thiab lwm yam lag luam.
Caustic soda, tshuaj lub npe sodium hydroxide, dawb translucent flaky khoom, yog ib tug yooj yim tshuaj raw khoom, lug siv nyob rau hauv papermaking, hluavtaws detergents thiab soaps, viscose fibers, rayon thiab paj rwb fabrics thiab lwm yam lub teeb textile industries, tshuaj tua kab, Dyestuffs, roj hmab thiab tshuaj. kev lag luam, roj drilling, roj av refining thiab tar refining, raws li zoo raws li kev tiv thaiv kev lag luam, machinery kev lag luam, ntoo ua, metallurgical kev lag luam, tshuaj kev lag luam thiab kev tsim kho hauv nroog. Nws kuj yog siv rau hauv kev tsim cov tshuaj, ntawv, xab npum thiab detergents, rayon thiab cellophane, ua bauxite alumina, thiab mercerized textiles thiab dej kho.
