Habka diyaarinta dhaqameed ee sodium polyphosphate waa in laga takhaluso fosfoorikska kulul ee jajab tiro dhan 75% H3PO4 oo leh dambas soodhaha ah si loo helo slurry dhexdhexaad ah oo leh saamiga Na/P ee 5:3, oo lagu hayo diirimaad 70℃~90℃; ka dibna lagu buufiyo slurry-ka la helay foorno polymerization ah si loogu fuuq-baxo heerkulka sare, oo lagu qaso sodium tripolyphosphate qiyaastii 400℃. Habkan dhaqameed ma aha oo kaliya inuu u baahan yahay aashitada fosfoorikska kulul ee qaali ah, laakiin sidoo kale wuxuu isticmaalaa tamar kuleyl badan; marka lagu diyaarinayo slurry-ka dhexdhexaad ah, waxaa lagama maarmaan ah in la kululeeyo oo laga saaro CO2, hab-socodkuna waa mid adag. Inkasta oo aashitada fosfoorikska qoyan ee kiimikada lagu nadiifiyo loo isticmaali karo in lagu beddelo aashitada fosfoorikska kulul si loo soo saaro sodium tripolyphosphate, sababtoo ah maadada sare ee birta birta ah ee ku jirta aashitada fosfoorikska qoyan, way adag tahay in la buuxiyo shuruudaha tayada ee alaabada sodium tripolyphosphate ee hadda jira, waana ay adag tahay in la buuxiyo tilmaamayaasha lagu qeexay heerarka qaranka.
Waqtigan xaadirka ah, dadku waxay barteen habab cusub oo wax soo saar ah oo sodium tripolyphosphate ah, sida codsiga shatiga Shiinaha ee No. 94110486.9 "Habka loo soo saaro sodium tripolyphosphate", No. 200310105368.6 "Habka cusub ee loo soo saaro sodium tripolyphosphate", No. 200410040357.9 "Habka loo soo saaro sodium tripolyphosphate iyadoo la adeegsanayo hab dhammaystiran oo qalalan-qoyan", No. 200510020871.0 "Habka loo soo saaro sodium tripolyphosphate iyadoo la adeegsanayo habka kala-goynta laba-jibbaaran ee cusbada Glauber", 200810197998.3 "Habka loo soo saaro sodium tripolyphosphate iyo soo saarista ammonium chloride", iwm.; inkastoo xalalkan farsamo ay leeyihiin astaamo u gaar ah, badankood waa in la beddelo walxaha ceeriin ee dhexdhexaadinta ah.
Habka loo soo saaro sodium tripolyphosphate iyadoo la isticmaalayo sodium pyrophosphate cayriin ah
Sodium pyrophosphate-ka cayriin marka hore wuxuu galaa haanta dharka lagu dhaqo ee milixda si uu uga saaro inta badan sodium chloride-ka, ka dibna wuxuu galaa saxanka iyo shaabadda shaandhada si loogu sifeeyo shaabadda koowaad. Keegga shaandhada waxaa ku jira xaddi badan oo sodium pyrophosphate ah, tirada guud ee sodium chloride-kuna waa wax ka yar 2.5%. Dabadeed, xalka waxaa lagu kululeeyaa 85°C haanta kala dirida iyadoo la isticmaalayo uumi si loo walaaqo oo loo milmo. Sodium sulfide ayaa lagu daraa inta lagu jiro kala dirida si looga saaro ion-yada birta ah. Waxyaabaha aan milmi karin waa wasakh sida copper hydroxide. Mar labaad ayaa la sifeeyaa. Shaashadda waa xal sodium pyrophosphate ah. Kaarboon firfircoon ayaa lagu daraa shaashadda si looga saaro midabada, fosforic acid ayaa lagu daraa si loo aashito loona dedejiyo kala dirida, ugu dambayntiina alkali dareere ah ayaa lagu daraa si loo hagaajiyo qiimaha pH ilaa 7.5-8.5 si loo diyaariyo dareere la safeeyey.
Qayb ka mid ah dareeraha la safeeyey ayaa si toos ah loogu isticmaalaa qaybta diyaarinta dareeraha dhexdhexaadka ah ee sodium tripolyphosphate, qaybta kalena ee dareeraha la safeeyey waxaa lagu shubaa crystallizer-ka DTB. Dareeraha la safeeyey ee ku jira crystallizer-ka DTB waxaa lagu qaboojiyaa is-beddelka kulaylka iyadoo la adeegsanayo bamka wareegga qasabka ah iyo biyaha 5°C oo uu soo diro qaboojiyaha. Marka heerkulka xalka uu hoos u dhaco 15°C, waxaa loo rogaa flocs ka dibna waxaa loo qaadaa haanta heerka sare ah waxaana lagu centrifuge-ka si loo kala saaro centrifugal si loo helo kiristaalo sodium pyrophosphate ah. Kiristaalo sodium pyrophosphate ah ayaa lagu daraa qaybta diyaarinta dareeraha dhexdhexaadka ah ee habka wax soo saarka sodium tripolyphosphate waxaana lagu qasaa fosforic acid iyo soodhaha dareeraha ah ee caustic si loogu diyaariyo dareeraha dhexdhexaadka ah sidii walxaha ceeriin ah ee loogu talagalay soo saarista sodium tripolyphosphate. Bireega kor ku xusan waxaa loo soo celiyaa si loo dhaqo sodium pyrophosphate-ka cayriin; Marka maadada sodium chloride ee ku jirta milixda ay gaarto dhereg, milixda waxaa lagu shubaa taangiga kaydka, milixda ku jirta taangiga kaydka waxaa lagu shubaa jaakadda gaaska dabada sodium tripolyphosphate si ay kulaylka ugu beddesho gaaska dabada heerkulka sare leh. milixda ka dib is-weydaarsiga kulaylka waxay ku noqotaa taangiga kaydka si uu u uumi baxo.
