Ifomula yamakhemikhali: Na5P3O10
Isisindo se-molecule: 367.86
Izakhiwo: Impushana emhlophe noma ama-granules, ancibilika kalula emanzini. Ngokwezidingo zohlelo lokusebenza nokucubungula, singahlinzeka ngemikhiqizo yokucaciswa okuhlukahlukene njengokuminyana okuhlukile (0.5-0.9g/cm3), ukuncibilika okuhlukile (amanzi ayi-10g, 20g/100ml), i-sodium tripolyphosphate esheshayo, i-sodium tripolyphosphate enezinhlayiyana ezinkulu, njll.
Isebenzisa:
1.Embonini yokudla, isetshenziswa kakhulu njengesithuthukisi sekhwalithi sokudla okusemathinini, imikhiqizo yobisi, iziphuzo zejusi yezithelo nobisi lwesoya; into yokugcina amanzi kanye nethenda yemikhiqizo yenyama efana nenyama nenyama yesidlo sasemini; ingagcina amanzi, ithenda, inwebe futhi ibe mhlophe ekucutshungulweni kwemikhiqizo yasemanzini; ingathambisa isikhumba sikabhontshisi obanzi kubhontshisi obanzi osemathinini; ingasetshenziswa futhi njengesithambisi samanzi, i-chelating agent, isilawuli se-PH kanye nokujiya, kanye nasembonini kabhiya.
2. Emkhakheni wezimboni, isetshenziswa kakhulu ezintweni zokuhlanza njenge-ejenti esizayo, i-soap synergist kanye nokuvimbela insipho yebha ukuthi ingacwebezeli futhi iqhakaze, isithambisa samanzi sezimboni, i-agent pretanning yesikhumba, insiza yokudaya, i-ejenti yokulawula udaka kahle kawoyela, ukuvimbela ukungcoliswa kukawoyela. i-ejenti yokwenza iphepha, i-disperant ephumelelayo yokwelapha ukumiswa njengopende, i-kaolin, i-magnesium i-oxide, i-calcium carbonate, njll., ne-ceramic degumming ejenti nesinciphisi samanzi embonini ye-ceramic.
Indlela yokulungiselela yendabuko ye-sodium polyphosphate iwukuqeda amandla e-phosphoric acid enengxenye enkulu engu-75% H3PO4 ngokumiswa komlotha wesoda ukuze kutholwe udaka olune-Na/P isilinganiso esingu-5:3, futhi uyigcine ifudumele ku-70 ℃ ~. 90℃; bese ufafaza i-slurry etholiwe esithandweni se-polymerization ukuze uphelelwe amanzi emzimbeni ekushiseni okuphezulu, futhi uyihlanganise ku-sodium tripolyphosphate cishe ku-400 ℃. Le ndlela yendabuko ayidingi nje kuphela i-hot phosphoric acid ebizayo, kodwa futhi idla amandla amaningi okushisa; ngaphezu kwalokho, lapho ulungiselela i-slurry ngokungathathi hlangothi, kuyadingeka ukushisa nokukhipha i-CO2, futhi inqubo iyinkimbinkimbi. Nakuba i-phosphoric acid ehlanjululwe ngamakhemikhali ingasetshenziswa ukufaka esikhundleni se-hot phosphoric acid ukukhiqiza i-sodium tripolyphosphate, ngenxa yokuqukethwe okuphezulu kwensimbi yensimbi ku-phosphoric acid emanzi, kunzima ukuhlangabezana nezidingo zekhwalithi yemikhiqizo yamanje ye-sodium tripolyphosphate, futhi kubuye kube nzima. okunzima ukuhlangabezana nezinkomba ezishiwo kumazinga kazwelonke.
Njengamanje, abantu baye bafunda izinqubo ezintsha zokukhiqiza ze-sodium tripolyphosphate, njengesicelo se-patent yamaShayina No. 94110486.9 "Indlela yokukhiqiza i-sodium tripolyphosphate", No. 200310105368.6 "Inqubo entsha yokukhiqiza i-sodium tripolyphosphate", No. ukukhiqiza i-sodium tripolyphosphate ngokumanzi okomile indlela ebanzi", No. 200510020871.0 "Indlela yokukhiqiza i-sodium tripolyphosphate nge-Glauber's salt double decomposition method", 200810197998.3 "Indlela yokukhiqiza i-sodium tripolyphosphate kanye nokukhiqiza i-ammonium chloride", njll.; nakuba lezi zixazululo zobuchwepheshe zinezici zazo, eziningi zazo ezokushintsha izinto zokusetshenziswa kwe-neutralization.
Indlela yokukhiqiza i-sodium tripolyphosphate usebenzisa i-sodium pyrophosphate engahluziwe
I-sodium pyrophosphate engahluziwe ingena kuqala ethangini lokuwasha usawoti ukuze ikhiphe iningi le-sodium chloride, bese ingena epuletini nesihlungi somshini ukuze ihlungwe. Ikhekhe lokuhlunga liqukethe inani elikhulu le-sodium pyrophosphate, futhi ukuhlushwa kwe-sodium chloride kungaphansi kuka-2.5%. Khona-ke, isixazululo sishisiswe ku-85 ° C ku-tank yokuchithwa nge-steam yokugqugquzela nokuqedwa. I-sodium sulfide yengezwa ngesikhathi sokuchithwa ukuze kukhishwe ama-ion ensimbi. I-insoluble matter ukungcola okufana ne-copper hydroxide. Iyahlungwa futhi okwesibili. I-filtrate iyisisombululo se-sodium pyrophosphate. Ikhabhoni ecushiwe yengezwa ku-filtrate ukuze kukhishwe i-pigments, i-phosphoric acid yengezwa ku-acidify futhi isheshise ukuchithwa, futhi ekugcineni i-alkali ewuketshezi yengezwa ukulungisa inani le-pH libe ngu-7.5-8.5 ukuze kulungiswe uketshezi olucolisisiwe.
Ingxenye yoketshezi olucolisisiwe isetshenziswa ngokuqondile engxenyeni yokulungiselela uketshezi lwe-sodium tripolyphosphate neutralization, kanti enye ingxenye yoketshezi olucolisisiwe iphonswa ku-crystallizer ye-DTB. Uketshezi olucolisisiwe ku-crystallizer ye-DTB lupholiswa kusishintshi sokushisa ngephampu yokujikeleza ephoqelelwe kanye namanzi angu-5°C athunyelwa isibandisi. Uma izinga lokushisa lesixazululo lehla laya ku-15°C, lifakwa ikristalu libe yizicucu bese lithuthwa liyiswe kuthangi lezinga eliphezulu bese lifakwa ku-centrifuge ukuze kuhlukaniswe i-centrifugal ukuze kutholwe amakristalu e-sodium pyrophosphate. Amakristalu e-sodium pyrophosphate anezelwa esigabeni sokulungiswa koketshezi lwe-neutralization ohlelweni lokukhiqiza lwe-sodium tripolyphosphate futhi axutshwe ne-phosphoric acid ne-liquid caustic soda ukulungisa uketshezi lwe-neutralization njengempahla eluhlaza yokukhiqizwa kwe-sodium tripolyphosphate. I-brine eshiwo ngenhla ibuyiselwa ukugeza i-sodium pyrophosphate engahluziwe; lapho okuqukethwe kwe-sodium chloride ku-brine kufinyelela ku-saturation, i-brine iphonswa ethangini le-buffer, kanye ne-brine ethangini le-buffer iphonswa ku-sodium tripolyphosphate tail gas duct jacket ukushintsha ukushisa negesi yomsila enezinga eliphezulu lokushisa. I-brine ngemva kokushintshana kokushisa ibuyela ku-buffer tank ukuze ihwamuke.
