Saddexjibbaaran superphosphate ee Bacriminta Fosfatka
Triple superphosphate (TSP), waxaa lagu sameeyaa fosfooraska acid iyo dhagaxa fosfooraska ee dhulka.Waa bacriminta fosfateetka ah ee biyaha ku milma ee xoogga badan, waxaana si ballaaran loo isticmaalaa carro badan.Waxaa loo isticmaali karaa inay noqoto bacriminta aasaasiga ah, bacriminta dheeraadka ah, bacriminta jeermiska iyo alaabta ceeriin ee wax soo saarka bacriminta isku dhafan.
TSP waa bacriminta fosfooraska degdega ah ee biyaha ku milma, iyo ka kooban fosfooraska waxtarka leh waa 2.5 ilaa 3.0 jeer ka calcium caadiga ah (SSP).Alaabta waxaa loo isticmaali karaa sida bacriminta aasaasiga ah, labiska sare, bacriminta abuurka iyo alaabta ceeriin ee wax soo saarka bacriminta isku dhafan;si weyn loogu isticmaalo bariiska, sarreenka, galleyda, masagada, suufka, miraha, khudaarta iyo dalagyada kale ee cuntada iyo dalagga dhaqaalaha;si weyn loogu isticmaalo carrada cas iyo carrada jaalaha ah, carrada bunni, carrada fluvo-aquic jaalaha ah, ciidda madow, ciidda qorfe, ciidda guduudan, carrada albic iyo tayada kale ee ciidda.
In la qaato habka kiimikaad ee soo jireenka ah (Habka Den) ee wax soo saarka.
Budada dhagaxa Phosphate (slurry) waxay la falgashaa sulfuric acid si ay u kala saarto dareeraha-adag si ay u hesho habka-qoyan ee fosfooraska acid.Ka dib fiirsashada, fosfooraska acid ee xoogga leh ayaa la helaa.Aashitada fosfooraska ee xoogga leh iyo budada dhagaxa fosfatetada ayaa isku dhafan (kiimiko ahaan loo sameeyay), iyo walxaha falcelinta waa la is dulsaaray oo qaan gaadhay, granulated, engejiyey, shaandheyn, (haddii loo baahdo, xirmo ka hortagga-caking), oo la qaboojiyey si loo helo alaabta.
Superphosphate, sidoo kale loo yaqaan superphosphate caadiga ah, waa bacriminta fosfatetada si toos ah loogu diyaariyey iyada oo la gooyey dhagaxa fosfatetada leh sulfuric acid.Qaybaha ugu muhiimsan ee waxtarka leh waa calcium dihydrogen phosphate hydrate Ca (H2PO4) 2 · H2O iyo qadar yar oo ah fosfooraska bilaashka ah, iyo sidoo kale calcium sulfate anhydrous ah (waxtar u leh carrada sulfur-yarida).Calcium superphosphate wuxuu ka kooban yahay 14% ~ 20% wax ku ool ah P2O5 (80% ~ 95% kaas oo ku milma biyaha), kaas oo leh bacriminta fosfatetada si degdeg ah u milma biyaha.Cawlan ama budo cad (ama qaybo) ayaa si toos ah loogu isticmaali karaa sida bacriminta fosfatetada.Waxa kale oo loo isticmaali karaa walxo samaynta bacriminta isku dhafan.
Bacriminta cawl aan midab lahayn ama khafiif ah (ama budo).Solubility intooda badan si fudud ayay ugu milmi karaan biyaha, qaar yarna waa kuwo aan lagu milmi karin biyaha oo si fudud ugu milmaya 2% citric acid (xalka citric acid).
