I-superphosphate kathathu kwizichumiso zePhosphate
I-superphosphate ephindwe kathathu (TSP) yenziwe nge-asidi ye-phosphoric egxininisiweyo kunye nelitye le-phosphate yomhlaba. Isichumiso sephosphate esinyibilikayo samanzi, kwaye sisetyenziswa ngokubanzi kumhlaba omninzi. Ingasetyenziselwa ukuba sisichumisi esisisiseko, isichumisi esongezelelweyo, isichumisi sentsholongwane kunye nemathiriyeli ekrwada ukuvelisa isichumiso esixutyiweyo.
I-TSP yi-high-concentration, i-soluble water-soluble quick acting phosphate fertilizer, kunye nomxholo wayo osebenzayo we-phosphorus yi-2.5 ukuya ku-3.0 amaxesha e-calcium eqhelekileyo (SSP). Imveliso ingasetyenziswa njengesichumiso esisisiseko, isigqubuthelo esingaphezulu, isichumisi sembewu kunye nezixhobo ezikrwada ukuvelisa isichumiso esixutyiweyo; isetyenziswa kakhulu kwirayisi, ingqolowa, umbona, amazimba, umqhaphu, iziqhamo, imifuno kunye nezinye izityalo zokutya kunye nezityalo zoqoqosho; isetyenziswa kakhulu kumhlaba obomvu kunye nomhlaba omthubi , Umhlaba omdaka, umhlaba omthubi we-fluvo-aquic, umhlaba omnyama, umhlaba wesinamoni, umhlaba omfusa, umhlaba we-albic kunye nezinye iimpawu zomhlaba.
Yamkelwe indlela yemichiza yemveli (indlela yeDen) yokuvelisa.
I-Phosphate rock powder (slurry) idibana ne-asidi ye-sulfuric ukwenzela ulwahlulo olululwelo oluqinileyo ukuze kufumaneke inkqubo emanzi yokuhlambulula iasidi ye-phosphoric. Emva koxinzelelo, i-asidi ye-phosphoric egxininisiweyo ifunyenwe. I-asidi ye-phosphoric egxininisiweyo kunye ne-phosphate rock powder zixutywe (zenziwe ngokwekhemikhali), kwaye izinto zokusabela zifakwe kwaye zivuthwe, zihlanjululwe, zomiswe, zihlungwe, (ukuba kuyimfuneko, iphakheji yokulwa ne-caking), kwaye ipholile ukufumana imveliso.
I-Superphosphate, ekwabizwa ngokuba yi-superphosphate eqhelekileyo, sisichumiso sephosphate esilungiswe ngokuthe ngqo ngokubola kwelitye le-phosphate nge-asidi ye-sulfuric. Amacandelo aluncedo kakhulu yi-calcium dihydrogen phosphate hydrate Ca (H2PO4) 2 · H2O kunye nentwana ye-asidi ye-phosphoric yasimahla, kunye ne-anhydrous calcium sulfate (iluncedo kumhlaba oswele isalfure). I-calcium superphosphate iqulethe i-14% ~ 20% esebenzayo ye-P2O5 (i-80% ~ 95% yayo inyibilika emanzini), eyesichumisi se-phosphate esine-soluble esebenza ngokukhawuleza. Umgubo ongwevu okanye ongwevu omhlophe (okanye amasuntswana) angasetyenziswa ngokuthe ngqo njengesichumiso sephosphate. Isenokusetyenziswa njengesithako sokwenza isichumisi esixandileyo.
Isichumiso esingenambala okanye esingwevu esikhanyayo (okanye umgubo). Ukunyibilika uninzi lwazo lunyibilika ngokulula emanzini, kwaye ezimbalwa azinyibiliki emanzini kwaye zinyibilika ngokulula kwi-2% ye-citric acid (isisombululo se-citric acid).
