CAS: 7783-28-0
1.Diammonium phosphate, sidoo kale loo yaqaan diammonium hydrogen phosphate (DAP), waa bacriminta isku dhafan oo ka kooban nitrogen iyo fosfooraska.Diammonium hydrogen phosphate waa fiirsashada sare ee bacriminta dhaqsaha badan.Kiimikada buuggu si sahal ah ayuu ugu milmi karaa biyaha wuxuuna leeyahay walxo aan adagayn marka la milmo ka dib.Waxay ku habboon tahay dhammaan noocyada dalagyada iyo carrada, gaar ahaan dalagyada jecel nitrogen oo u baahan fosfooraska.Waxaa loo isticmaali karaa sida bacriminta salka ama dusha sare, waxayna ku habboon tahay codsiga qoto dheer.
2.Diammonium phosphate waxaa loola jeedaa alaabta caadiga ah, taas oo ka kooban N18% iyo p2o548%.Qaabka crystal-ka ayaa ah mid fidsan iyo prism oblique ah.Ku milanka biyaha ee 25 ℃ waa 71%.pH ee xalkeeda saturated waxa ay gaadhaa 8, taas oo aad uga saraysa buuga kiimikaad ee monoammonium phosphate.Sababtoo ah xalka buuxa ee diammonium phosphate waa alkaline, codsanaya ciidda acidic waxay yareyn kartaa hagaajinta birta iyo aluminium ee fosfooraska, si fosfooraska ay u ahaato mid waxtar leh.Sidaa darteed, diammonium phosphate waxaa lagu talinayaa in loo isticmaalo ciidda acidic ah.
3.Colorless transparent monoclinic crystal ama budo cad.Ku milmay biyaha, aan lagu milmi karin khamriga, acetone iyo ammonia.
4. Waqtigan xaadirka ah, hababka ugu muhiimsan ee wax soo saarka warshadaha waxaa ka mid ah fosfooraska kulaylka iyo fosfooraska soo saarista, taas oo ka falcelisa dareeraha ammonia si ay u soo saarto diammonium hydrogen phosphate.Midka hore wuxuu leeyahay nadiif sare, kan dambena wuxuu leeyahay qiimo jaban.Dhexdhexaadinta fosfooraska aashitada kulaylka ah ee dareeraha dareeraha ammonia waxay ku milmaan fosfooraska kuleylka kulaylka biyo nadiif ah (biyaha: phosphoric acid = 1.3: 1) galay fosfooraska aashitada milmi, ku tuuji fal-celinta tuubada ee marxaladda koowaad si ay uga takhalusto ammonia, ku rid xalalka falcelinta ee labaad. Marxaladda tubada reactor si ay uga sii falceliso ammonia, si qiimaha pH ee beddelka falcelinta falcelinta kiimikaadku gaadho 8.0, ku dar wakiilka ka saarista arsenic iyo wakiilka saarista birta culus si loo nadiifiyo xalka, shaandheeyo, loogana saaro wasakhda sida arsenic iyo biraha culus, Shaandhaynta waxaa loo diraa haanta hagaajinta ganaaxa si loo hagaajiyo qiimaha pH ilaa 7.8 ~ 8.0, loo diro uumiga si uumi-baxsan iyo fiirsashada cufnaanta qaraabada ee 1.3, loo diro crystallizer qaboojinta, qaboojiyey iyo crystallized, centrifuged si loo kala saaro dareeraha hooyada. , oo la qalajiyey si loo helo badeecada dhammaatay ee diammonium hydrogen phosphate la cuni karo.Its h3po4+2nh3 → (NH4) 2HPO4 .
Codsiga
1.Waxa loo isticmaalaa sida wax lagu daro quudinta, ololka retardant iyo wakiilka dab-damiska ee warshadaha
2.S anlytical reagent and buffer, waa bacriminta biyaha jilciya-wax ku ool ah oo si ballaaran loogu isticmaalo khudaarta, miraha, bariiska iyo sarreenka;Cuntada khamiirka, iwm.
3.In warshadaha cuntada, waxaa loo isticmaalaa sida wakiilka bulking cuntada, nidaamiyaha cajiinka, quudinta khamiirka, iyo kaaliyaha halsano ee breing.Waxa loo isticmaali karaa sidii bakhaar.
4. Sida wax lagu daro buug kiimikaad oo loogu talagalay ariga.
5.Waxa loo isticmaalaa daabacaadda saxan samaynta, dawooyinka, ka hortagga dabka, tubbada elektarooniga ah iyo ujeedooyin kale.Heerka bacriminta waxaa inta badan loo isticmaalaa sida nitrogen-fiirsashada sare iyo bacriminta ka kooban fosfooraska.
Darajada 6.Industrial waxaa loo isticmaalaa in lagu dhejiyo alwaax iyo dhar si loo kordhiyo cimrigooda;Waxaa loo isticmaali karaa sida wakiilka dab-demiska budada qalalan iyo fosfooraska nalalka dhaadheer;Waxa kale oo loo isticmaalaa daabacaadda iyo samaynta saxannada, samaynta tuubooyinka elektaroonigga ah, ceramics, dhaldhalaalka, iwm., iyo daaweynta biochemical ee biyaha wasakhda ah;Dab-dejinta ololka oo loo isticmaalo sida walxaha dahaadhka kulaylka ee mishiinka gantaallada ee warshadaha milatariga.
