Zvichienderana nezvinodiwa zvekushandisa nekugadzirisa, tinogona kupa zvigadzirwa zvakasiyana-siyana zvakaita sehuwandu hwakasiyana (0.5-0.9g/cm3), kunyungudika kwakasiyana (10g, 20g/100ml mvura), instant sodium tripolyphosphate, large-particle sodium tripolyphosphate, nezvimwewo.
Mashandisirwo:
1. Muindasitiri yezvekudya, inonyanya kushandiswa semuchina wekuvandudza mhando yezvikafu zvemumagaba, zvigadzirwa zvemukaka, zvinwiwa zvemuto wemichero nemukaka wesoya; chinhu chinochengetedza mvura uye chinonyorovesa zvigadzirwa zvenyama zvakaita seham nenyama yemasikati; chinogona kuchengetedza mvura, kunyorovesa, kuwedzera uye kutsvaira mukugadzirwa kwezvigadzirwa zvemumvura; chinogona kunyorovesa ganda rebhinzi dziri mubhinzi dziri mugaba; chinogona zvakare kushandiswa semuchina wekunyorovesa mvura, chelating agent, PH regulator uye thickener, pamwe nemuindasitiri yedoro.
2. Mundima yemaindasitiri, inoshandiswa zvakanyanya mumasipo semushonga wekubatsira, sipo inobatanidza uye kudzivirira sipo yemabhawa kuti isaite crystallize uye kutumbuka, inonyorovesa mvura yemuindasitiri, dehwe rinogadzira ganda, mubatsiri wekudhaya, mushonga wekutonga madhaka mutsime remafuta, mushonga wekudzivirira kusvibiswa kwemafuta wekugadzira mapepa, muparadzi anoshanda pakurapa suspensions dzakadai sependi, kaolin, magnesium oxide, calcium carbonate, nezvimwewo, uye mushonga wekubvisa gumming weceramic uye munoderedza mvura muindasitiri yemaceramic.
Nzira yechinyakare yekugadzirira sodium polyphosphate ndeyekubvisa hot phosphoric acid nechikamu che75% H3PO4 nesoda ash suspension kuti uwane slurry isina kukanganiswa ine Na/P ratio ye5:3, uye irambe ichidziya pa70℃ ~ 90℃; wobva wapfapfaidza slurry yakawanikwa mu polymerization furnace kuti isanyatsobuda mvura pakupisa kwakanyanya, woisanganisa mu sodium tripolyphosphate pa400℃. Iyi nzira yechinyakare haingodi chete hot phosphoric acid inodhura, asiwo inoshandisa simba rakawanda rekupisa; pamusoro pezvo, pakugadzirira slurry ne neutralization, zvakakosha kupisa nekubvisa CO2, uye maitiro acho akaoma. Kunyangwe wet phosphoric acid yakacheneswa nemakemikari inogona kushandiswa kutsiva hot phosphoric acid kugadzira sodium tripolyphosphate, nekuda kwehuwandu hwakawanda hwesimbi mu wet phosphoric acid, zvakaoma kusangana nezvinodiwa zvemhando ye sodium tripolyphosphate zvigadzirwa zviripo, uye zvakaomawo kusangana nezviratidzo zvakataurwa mumitemo yenyika.
Parizvino, vanhu vakadzidza mamwe maitiro matsva ekugadzira sodium tripolyphosphate, akadai seChinese patent application Nhamba 94110486.9 "Nzira yekugadzira sodium tripolyphosphate", Nhamba 200310105368.6 "Nzira itsva yekugadzira sodium tripolyphosphate", Nhamba 200410040357.9 "Nzira yekugadzira sodium tripolyphosphate nenzira yakaoma-yakanyorova", Nhamba 200510020871.0 "Nzira yekugadzira sodium tripolyphosphate nenzira yeGlauber's salt double decomposition", 200810197998.3 "Nzira yekugadzira sodium tripolyphosphate uye by-producing ammonium chloride", nezvimwewo; kunyangwe mhinduro idzi dzehunyanzvi dziine hunhu hwadzo, zhinji dzadzo ndedzekuchinja neutralization mbishi zvinhu.
Nzira yekugadzira sodium tripolyphosphate uchishandisa crude sodium pyrophosphate
Sodium pyrophosphate isina kucheneswa inotanga yapinda mutangi rekuwachisa munyu kuti ibvise sodium chloride yakawanda, yozopinda muplate neframe filter press kuti isvine. Keke refirita rine sodium pyrophosphate yakawanda, uye huwandu hwakawanda hwesodium chloride huri pasi pe2.5%. Zvadaro, mhinduro yacho inopiswa kusvika 85°C mutangi rekuyeresa neutsi hwekukurunga nekunyungudutsa. Sodium sulfide inowedzerwa panguva yekunyunguduka kubvisa maion esimbi. Chinhu chisinganyungudike tsvina yakaita se copper hydroxide. Inoseferwa zvakare kechipiri. Filtrate i sodium pyrophosphate solution. Activated carbon inowedzerwa mu filtrate kubvisa pigments, phosphoric acid inowedzerwa kuti iite acidify uye ikurumidze kunyunguduka, uye pakupedzisira liquid alkali inowedzerwa kugadzirisa pH value kusvika 7.5-8.5 kugadzira mvura yakacheneswa.
Chikamu chemvura yakacheneswa chinoshandiswa zvakananga muchikamu chekugadzirira sodium tripolyphosphate neutralization liquid, uye chimwe chikamu chemvura yakacheneswa chinopombwa muDTB crystallizer. Mvura yakacheneswa muDTB crystallizer inotonhodzwa muheat exchanger neforced circulation pombi uye 5°C mvura inotumirwa nechiller. Kana tembiricha yemvura yadzikira kusvika 15°C, inogadzirwa kuita flocs uye yozoendeswa kutangi repamusoro-soro uye inoiswa mucentrifuge kuti iparadzaniswe necentrifugal kuti iwane sodium pyrophosphate crystals. Sodium pyrophosphate crystals inowedzerwa muchikamu chekugadzirira neutralization liquid mukugadzirwa kwesodium tripolyphosphate uye inosanganiswa nephosphoric acid uye liquid caustic soda kugadzirira neutralization liquid sezvinhu zvekugadzira sodium tripolyphosphate. Brine yataurwa pamusoro apa inodzoserwa kuti isukure crude sodium pyrophosphate; Kana huwandu hwesodium chloride mubrine hwasvika pakuzara, brine inopombwa mutangi rebuffer, uye brine iri mutangi rebuffer inopombwa mujaketi re sodium tripolyphosphate tail gas duct kuti ichinje kupisa negasi remuswe rinopisa zvakanyanya. Brine mushure mekuchinjwa kwekupisa inodzokera mutangi rebuffer kuti ipfuure.
