Usebenzisa:
I-1.Kwishishini lokutya, isetyenziswa ikakhulu njengokuphucula umgangatho wokutya okusemathinini, iimveliso zobisi, iziselo zejusi yeziqhamo kunye nobisi lwesoya; indawo yokugcina amanzi kunye ne-tenderiza kwiimveliso zenyama ezifana ne-ham kunye nenyama yesidlo sasemini; inokugcina amanzi, ithenda, yandise kunye nebleach ekusetyenzweni kweemveliso zasemanzini; inokuthambisa ulusu lweembotyi ezibanzi kwiimbotyi ezibanzi ezinkonkxiweyo; isenokusetyenziswa njengesithambisi samanzi, i-agent echelating, isilawuli se-PH kunye nesingqimba, kunye nakwishishini lebhiya.
2. Kwintsimi yoshishino, isetyenziswa ngokubanzi kwizinto zokucoca njenge-ejenti encedisayo, i-sepha synergist kunye nokuthintela isepha ye-bar ekukhanyeni kunye nokuqhakaza, ukuthambisa amanzi kwimizi-mveliso, i-agent ye-leather pretanning, i-ejenti yokudaya, i-oyile yokulawula udaka, ukuthintela ukungcoliswa kwe-oyile. iarhente yokwenza iphepha, i-dispersant esebenzayo kunyango lokumiswa njengepeyinti, i-kaolin, i-magnesium i-oxide, i-calcium carbonate, njl., kunye ne-agent ye-ceramic degumming kunye nokunciphisa amanzi kwi-ceramic industry.
Indlela yokulungiselela yendabuko ye-polyphosphate ye-sodium kukunciphisa i-asidi eshushu ye-phosphoric kunye neqhekeza elikhulu le-75% ye-H3PO4 kunye ne-soda ash suspension ukuze ufumane i-slurry engathathi hlangothi kunye ne-Na / P ratio ye-5: 3, kwaye uyigcine ishushu kwi-70 ℃ ~. 90℃; emva koko utshize i-slurry efunyenweyo kwisithando se-polymerization sokuphelelwa ngamanzi emzimbeni kwiqondo lokushisa eliphezulu, kwaye uyidibanise kwi-sodium tripolyphosphate malunga ne-400 ℃. Le ndlela yemveli ayifuni kuphela i-asidi ye-phosphoric eshushu ebiza kakhulu, kodwa iphinda isebenzise amandla amaninzi okushisa; ukongezelela, xa ulungiselela i-slurry ngokungathathi hlangothi, kuyimfuneko ukutshisa nokususa i-CO2, kwaye inkqubo inzima. Nangona i-asidi emanzi ye-phosphoric ehlanjululwe ngokwemichiza ingasetyenziselwa ukutshintsha i-asidi ye-phosphoric eshushu ukuvelisa i-sodium tripolyphosphate, ngenxa yomxholo ophezulu wentsimbi yesinyithi kwi-asidi ye-phosphoric emanzi, kunzima ukuhlangabezana neemfuno zomgangatho weemveliso zangoku ze-sodium tripolyphosphate, kwaye kunjalo kwakhona. kunzima ukuhlangabezana nezalathi ezichazwe kwimigangatho yesizwe.
Okwangoku, abantu baye bafunda ezinye iinkqubo ezintsha zokuvelisa i-sodium tripolyphosphate, njengesicelo se-patent yaseTshayina No. 94110486.9 "Indlela yokuvelisa i-sodium tripolyphosphate", No. ukuvelisa i-sodium tripolyphosphate nge-dry-wet indlela ebanzi ", No. 200510020871.0 "Indlela yokuvelisa i-sodium tripolyphosphate nge-Glauber's salt decomposition method double", 200810197998.3 "Indlela yokuvelisa i-sodium tripolyphosphate kunye nokuvelisa i-ammonium chloride", njl. nangona ezi zisombululo zobugcisa zineempawu zazo, uninzi lwazo kukutshintsha i-neutralization imathiriyeli ekrwada.
Indlela yokuvelisa i-sodium tripolyphosphate usebenzisa i-pyrophosphate ye-sodium ekrwada
I-sodium pyrophosphate ekrwada ingena kuqala kwitanki yokuhlamba ityuwa ukuze isuse uninzi lwesodium chloride, ize ke ingene kwipleyiti kunye nefreyimu yokucoca i-filtration yokuqala. Ikhekhe lokucoca liqulethe inani elikhulu le-sodium pyrophosphate, kwaye ubuninzi be-sodium chloride bungaphantsi kwe-2.5%. Emva koko, isisombululo sishushu kwi-85 ° C kwi-tank yokuchithwa kunye ne-steam yokuvuselela kunye nokuchithwa. I-sodium sulfide yongezwa ngexesha lokuchithwa ukususa i-ion zetsimbi. Umba ongenakunyibilika bubumdaka obufana ne-copper hydroxide. Iyahluzwa kwakhona okwesibini. Ifiltrate sisisombululo sesodium pyrophosphate. Ikhabhoni esebenzayo yongezwa kwi-filtrate ukususa i-pigments, i-asidi ye-phosphoric yongezwa kwi-acidify kwaye ikhawuleze ukuchithwa, kwaye ekugqibeleni i-alkali yolwelo yongezwa ukulungisa ixabiso le-pH kwi-7.5-8.5 ukulungiselela ulwelo olusulungekileyo.
Inxalenye yolwelo esulungekisiweyo isetyenziswa ngokuthe ngqo kwicandelo lokulungisa ulwelo lwe-sodium tripolyphosphate neutralization, kwaye enye inxalenye yolwelo esulungekisiweyo impontshelwa kwicrystallizer ye-DTB. I-liquid ecocekileyo kwi-crystallizer ye-DTB ipholile kwi-heat exchanger ngokunyanzeliswa kwepompo yokujikeleza kunye ne-5 ° C yamanzi athunyelwe yi-chiller. Xa iqondo lokushisa lesisombululo liyehla ukuya kwi-15 ° C, i-crystallized ibe yi-flocs kwaye emva koko ihanjiswe kwi-tank yezinga eliphezulu kwaye ifakwe kwi-centrifuge kwi-centrifuge yokwahlukana kwe-centrifugal ukufumana i-crystals ye-sodium pyrophosphate. Iikristale zesodium pyrophosphate zongezwa kwicandelo lokulungisa ulwelo lwe-neutralization kwinkqubo yokuvelisa i-sodium tripolyphosphate kwaye ixutywe ne-phosphoric acid kunye nesoda ye-caustic engamanzi ukulungiselela ulwelo lwe-neutralization njengento ekrwada yokuveliswa kwe-sodium tripolyphosphate. Le brine ikhankanywe ngasentla ibuyiselwa ukuhlamba i-pyrophosphate yesodium ekrwada; xa isiqulatho sekloridi yesodium kwibrine sifikelela kwisaturation, i-brine impontshelwa kwitanki yesithinteli, kunye nebrine ekwitanki yesithinteli impontshelwa kwibhatyi yegesi yesodium tripolyphosphate umsila wokutshintshisa ubushushu kunye nerhasi yobushushu obuphezulu. I-brine emva kokutshintshiselana kobushushu ibuyela kwitanki yesithinteli ukuze ibe ngumphunga.
