Triple superphosphate muPhosphate Fertilizer
Triple superphosphate (TSP), Inogadzirwa neyakaomeswa phosphoric acid uye pasi phosphate rock. Iyo yakanyanya kunyungudika mvura soluble phosphate fertilizer, uye inoshandiswa zvakanyanya kune ivhu rakawanda. Inogona kushandiswa kuita fetireza yekutanga, fetereza yekuwedzera, fetireza yezvipembenene uye zvishandiswa pakugadzira fetereza yekomboni.
TSP ndeyepamusoro-concentration, mvura-inonyungudika inokurumidza kuita phosphate fetiraiza, uye inoshanda phosphorus inokwana 2.5 kusvika 3.0 nguva yeyakajairika calcium (SSP). Chigadzirwa chacho chinogona kushandiswa sefetireza yepasi, yekupfekedza yepamusoro, fetereza yembeu uye midziyo yekugadzira fetereza yekomboni; inoshandiswa zvakanyanya mupunga, gorosi, chibage, mhunga, donje, michero, miriwo nezvimwe zvirimwa zvekudya uye zvirimwa zvehupfumi; yakashandiswa zvakanyanya muvhu dzvuku uye yero ivhu , Brown ivhu, yero fluvo-aquic ivhu, ivhu dema, sinamoni ivhu, yepepuru ivhu, albic ivhu uye humwe hunhu hwevhu.
Igamuchirwe iyo yechinyakare makemikari nzira (Den nzira) yekugadzira.
Phosphate rock powder (slurry) inopindirana ne sulfuric acid yemvura-yakasimba kupatsanurwa kuti iwane wet-process dilute phosphoric acid. Mushure mekugadzirisa, yakanyanyisa phosphoric acid inowanikwa. Yakaiswa phosphoric acid uye phosphate rock poda inosanganiswa (kemikari yakaumbwa), uye zvinhu zvinogadziriswa zvinoiswa uye zvakakura, granulated, dzakaomeswa, dzakapepetwa, (kana zvichidikanwa, anti-caking package), uye yakatonhodzwa kuti uwane chigadzirwa.
Superphosphate, inozivikanwawo seyakajairwa superphosphate, ndeye phosphate fetiraiza yakanyatsogadzirirwa nekuora phosphate rock ne sulfuric acid. Izvo zvakakosha zvinobatsira zvinoumba calcium dihydrogen phosphate hydrate Ca (H2PO4) 2 · H2O uye shoma shoma yemahara phosphoric acid, pamwe neanhydrous calcium sulfate (inobatsira kune sulfur inoshaya ivhu). Calcium superphosphate ine 14% ~ 20% inoshanda P2O5 (80% ~ 95% iyo inonyungudika mumvura), inova yemvura inonyungudika inokurumidza kuita phosphate fetereza. Gray kana grey chena poda (kana zvimedu) inogona kushandiswa zvakananga sefosfate fetiraiza. Inogona zvakare kushandiswa sechinhu chekugadzira fetereza yakasanganiswa.
Fetereza isina ruvara kana grey granular (kana hupfu). Solubility mazhinji acho anonyungudika nyore mumvura, uye mashoma haanyungudika mumvura uye anonyungudika nyore mu2% citric acid (citric acid solution).
