Inqubo yokukhiqiza kanye nokulungiselela ye-phosphate de monomonium

I-Phosphate de Monoammonium (PDA) iyinkimbinkimbi esetshenziswa ezimbonini ezahlukahlukene, kufaka phakathi ezolimo, ukucubungula ukudla kanye nokwelashwa kwamanzi. Ukuqonda inqubo yokukhiqiza kanye nokulungiselela i-PDA kungasikhanyisela ukusetshenziswa kwayo nokubaluleka kwayo emikhakheni ehlukene.

I-Phosphate de Monoamonium, eyaziwa nangokuthi i-monomonium phosphate (Imephu), iyingxenye eyakhiwa ukusabela phakathi kwe-ammonia ne-phosphoric acid. Inefomula yamakhemikhali NH4H2PO4 futhi ibonwa kabanzi ngokusebenza kwayo nokusebenza kahle kwezicelo ezahlukahlukene.

Inqubo yokukhiqiza ye I-phosphate de monomonium (PDA)

1. Ukulungiselela i-phosphoric acid: Ukukhiqizwa kwe-PDA kuqala ngokulungiswa kwe-phosphoric acid. Le acid ivame ukususelwa edwaleni le-phosphate ngokusebenzisa inqubo yamakhemikhali eyaziwa ngokuthi inqubo emanzi noma inqubo ye-thermal. I-phosphate rock ithola ukwelashwa nge-sulfuric acid, okuholela ekwakhekeni kwe-phosphoric acid.
2. Isingeniso se-ammonia: Lapho i-acid ye-phosphoric itholakala, yahlanganiswa negesi ye-ammonia ye-anhydrous. I-ammonia yangeniswa emkhunjini wokuphendula lapho ihlangana khona ne-phosphoric acid engaphansi kwezimo ezilawulwayo. Lokhu kuphendula kwakha i-monoamonium phosphate (Imephu), i-Preperior to PDA.
3. I-Crystallization kanye nokomisa: Ngemuva kokusabela phakathi kwe-ammonia ne-phosphoric acid, isixazululo semephu esiphumela sifakwa kwinqubo yokuklabanisa. Lokhu kubandakanya ukupholisa isixazululo ukuvumela ukwakheka kwamakristalu aqinile we-monoamonium phosphate. Amakristalu ahlukaniswe ngoketshezi olusele ngokuhlunga noma nge-centrifugation. Amakristalu ahlukanisiwe ayagezwa ukususa ukungcola futhi omiswe ukuthola umkhiqizo wokugcina, i-phosphate de monomonium (PDA).

Izicelo ze-phosphate de monomonium (PDA)

1. Ezolimo kanye nomanyolo: I-Phosphate de Monomonium (PDA) isetshenziswa kabanzi njengomanyolo ngenxa yokuqukethwe kwayo okuphezulu kwe-phosphorus. Inikeza izakhi ezibalulekile ezitshalweni, ezikhuthaza ukukhula okunempilo, ukuthuthukiswa kwezimpande, kanye nesivuno sezitshalo esithuthukisiwe. I-PDA izuzisa ikakhulukazi izilimo ezidinga ukukhishwa okusheshayo kwe-phosphorus ngesikhathi sezigaba zazo zokuqala.
2. Ukusebenza kokudla: I-PDA iyisithako esivamile embonini yokudla, lapho isetshenziswa khona njenge-ejenti yokuvuka ekubhaka. Kuyasiza inhlama ikhuphuke ngokukhulula igesi ye-carbon dioxide lapho ivezwa ukushisa. I-PDA inomthelela ekuthunweni, ivolumu, kanye nekhwalithi ephelele yezimpahla ezibhakiwe ezinjengezinkwa, amakhekhe, namakhekhe.
3. Ukwelashwa kwamanzi: I-Phosphate de Monoammonium (PDA) idlala indima ebalulekile ezinhlelweni zokwelashwa kwamanzi, ikakhulukazi ngokulawula isilinganiso nokugqwala kuma-boilers kanye nezinhlelo zokupholisa. Kuyasiza ukuvimbela ukwakheka kwama-deposits esikalini futhi kuvimbela ukubhujiswa kwezindawo zensimbi. I-PDA nayo isetshenziswa ekwelashweni kwamanzi amdaka ukuze ususe izinsimbi ezisindayo ngokwakha ama-infoluble.

Ukugcina

I-Phosphate de Monoammonium (PDA) iyindawo ehlukahlukene enezicelo ezibalulekile kwezolimo, ukucubungula ukudla, kanye nokwelashwa kwamanzi. Ukuqonda inqubo yokukhiqiza kanye nokulungiselela i-PDA kuhlinzeka ngokuqonda ekubalulekeni nasekusebenzeni kwayo kwizimboni ezahlukahlukene. Ukusuka ekulungiseleleni kokuqala kwe-phosphoric acid ekwethulweni kwe-ammonia kanye nokomisa okulandelayo, isinyathelo ngasinye sinomthelela ekwakhiweni komkhiqizo wokugcina, phosphate de monomonium. Ngendima yayo njengomanyolo, umenzeli we-ragening, kanye nengxenye yokwelashwa kwamanzi, i-PDA iyaqhubeka nokufaka isandla ekukhuleni nasenhlalakahleni yemikhakha eminingi.
