Daim ntawv thov:
1. Nws yog ib qho tseem ceeb ntawm cov khoom nruab nrab hauv kev tsim cov tshuaj chiv kev lag luam, uas yog siv los tsim cov phosphate chiv thiab compound fertilizer.
2. Phosphoric acid kuj yog cov khoom siv raw ntawm phosphate thiab phosphate siv rau hauv xab npum, tshuaj ntxuav tes, tshuaj pleev xim hlau, khoom noj khoom haus additive, pub additive thiab dej kho tus neeg saib xyuas.
3. Flavoring Agent: Sagent nyob rau hauv tins, kua los yog dej haus thiab dej txias, hloov citric acid thiab.
Kev siv hluav taws xob: Feem ntau yog siv hauv electroplating, phosphating tov thiab industrial phosphate ntau lawm.
Kev Siv Khoom Noj Khoom Noj: Khoom noj khoom haus qib phosphoric acid feem ntau yog siv hauv kev lag luam tshuaj, qab zib thiab zaub mov. Tsuas yog siv ncaj qha rau hauv kev lag luam khoom noj (acidulants thiab poov xab as-ham hauv kev lag luam khoom noj xws li cola, npias, khoom qab zib, zaub xam lav roj, khoom noj siv mis, thiab lwm yam), feem ntau ntawm lawv yog siv los tsim cov khoom noj khoom haus qib phosphates, suav nrog. sodium, potassium, thiab calcium ntsev. , zinc ntsev, txhuas ntsev, polyphosphates, phosphoric acid ob ntsev, thiab lwm yam.
Pob: 25 kgs / hnab los yog raws li koj thov.
