Superphosphate atọ na fatịlaịza phosphate
Triple superphosphate (TSP), emebere ya site na phosphoric acid na ala phosphate nkume. Ọ bụ fatịlaịza phosphate soluble mmiri dị elu, a na-ejikwa ya maka ọtụtụ ala. Enwere ike iji ya bụrụ fatịlaịza bụ isi, fatịlaịza mgbakwunye, fatịlaịza germ na akụrụngwa maka imepụta fatịlaịza ngwakọta.
TSP bụ fatịlaịza phosphate na-eme ngwa ngwa nke na-eme ka mmiri dị elu, yana ọdịnaya phosphorus dị irè ya dị okpukpu 2.5 ruo 3.0 karịa nke calcium nkịtị (SSP). Enwere ike iji ngwaahịa a dị ka fatịlaịza ntọala, mgbakwasa n'elu, fatịlaịza mkpụrụ na akụrụngwa maka mmepụta fatịlaịza ngwakọta; a na-eji ya eme ihe na osikapa, ọka wit, ọka, sorghum, owu, mkpụrụ osisi, akwụkwọ nri na ihe ọkụkụ ndị ọzọ na nri akụ na ụba; A na-ejikarị ya eme ihe na ala uhie na ala edo edo , Ala Brown, odo fluvo-aquic ala, ala ojii, ala cinnamon, ala odo odo, ala albic na àgwà ala ndị ọzọ.
Nabata usoro kemịkalụ ọdịnala (usoro Den) maka mmepụta.
Phosphate nkume ntụ ntụ (slurry) na-emeghachi omume na sulfuric acid maka nkewa siri ike nke mmiri mmiri iji nweta mmiri-usoro itughari phosphoric acid. Mgbe itinye uche, a na-enweta phosphoric acid gbadoro anya. A na-agwakọta phosphoric acid na phosphate nkume ntụ ntụ (nke a na-emepụta kemịkalụ), na ihe mmeghachi omume na-ekpokọta ma tozuo, granulated, nke a mịrị amị, sieved, (ọ bụrụ na ọ dị mkpa, ngwugwu mgbochi-caking), ma dị jụụ iji nweta ngwaahịa ahụ.
Superphosphate, nke a makwaara dị ka superphosphate nkịtị, bụ fatịlaịza phosphate nke a kwadebere ozugbo site n'iwepụ nkume phosphate na sulfuric acid. Isi ihe bara uru bụ calcium dihydrogen phosphate hydrate Ca (H2PO4) 2 · H2O na obere ego nke phosphoric acid n'efu, yana calcium sulfate anhydrous (bara uru maka ala sulfur deficient). Calcium superphosphate nwere 14% ~ 20% P2O5 dị irè (80% ~ 95% nke soluble n'ime mmiri), nke bụ nke fatịlaịza phosphate na-eme ngwa ngwa na-agbaze mmiri. Enwere ike iji ntụ ntụ ma ọ bụ isi ntụ ntụ (ma ọ bụ akụkụ) mee ihe ozugbo dị ka fatịlaịza phosphate. Enwere ike iji ya dị ka ihe eji eme fatịlaịza.
Fatịlaịza granular (ma ọ bụ ntụ ntụ) na-enweghị agba ma ọ bụ dị ọkụ. Solubility ọtụtụ n'ime ha na-adị mfe mgbaze n'ime mmiri, na ole na ole na-esighi ike na mmiri na mfe soluble na 2% citric acid (citric acid ngwọta).
