Sodium tripolyphosphate ndi mtundu wa inorganic pawiri, woyera crystalline ufa, sungunuka m'madzi, alkaline njira, ndi amorphous madzi sungunuka liniya polyphosphate.Sodium tripolyphosphate ali ndi ntchito za chelating, kuyimitsa, dispersing, gelatinizing, emulsifying, pH buffering, etc. Angagwiritsidwe ntchito ngati zina waukulu wa kupanga detergent, mafakitale madzi softener, chikopa pretanning wothandizila, utoto wothandizila, organic synthesis chothandizira, chakudya zowonjezera. , ndi zina zotero
Ntchito zambiri za sodium tripolyphosphate:
1. Amagwiritsidwa ntchito makamaka ngati chothandizira popangira zotsukira, zopangira sopo komanso kuteteza mvula ndi chisanu chamafuta a sopo.Imakhala ndi emulsification yamphamvu pakupaka mafuta ndi mafuta, ndipo imatha kugwiritsidwa ntchito kusintha PH yamadzi a sopo a buffer.
Sodium tripolyphosphate ndi chinthu chofunikira kwambiri komanso chothandiza kwambiri pakutsukira, ndipo ntchito zake zazikulu zitha kufotokozedwa mwachidule motere.
① Chelation ya ayoni zitsulo
Madzi ochapira tsiku ndi tsiku amakhala ndi ayoni azitsulo zolimba (makamaka Ca2+, Mg2+).Panthawi yotsuka, iwo amapanga mchere wosasunthika wachitsulo ndi chinthu chogwira ntchito mu sopo kapena detergent, kotero kuti osati kokha kugwiritsira ntchito detergent kumawonjezeka, komanso nsalu pambuyo posamba imakhala ndi imvi yakuda yosasangalatsa.Sodium tripolyphosphate ali ndi katundu wabwino kwambiri wa chelating zitsulo zolimba ayoni, zomwe zimatha kuthetsa zovuta za ayoni zitsulo.
② Sinthani ntchito ya kusungunuka kwa gel osakaniza, emulsification ndi kubalalitsidwa
Dothi nthawi zambiri limakhala ndi zotupa za anthu (makamaka mapuloteni ndi mafuta), komanso zimakhala ndi mchenga ndi fumbi lochokera kunja.Komabe, sodium tripolyphosphate imakhala ndi zotsatira za kutupa ndi kusungunuka kwa mapuloteni ndipo imagwira ntchito ya colloidal solution.Kwa zinthu zamafuta, zimatha kulimbikitsa emulsification.Imakhala ndi dispersive kuyimitsidwa kwenikweni pa olimba particles.
③ kusungitsa mphamvu
Sodium tripolyphosphate imakhala ndi vuto lalikulu la alkaline, kotero kuti pH ya njira yotsuka imasungidwa pafupifupi 9.4, yomwe imathandizira kuchotsa dothi la asidi.
④ Ntchito yoletsa kuyika mikate
Detergent yaufa imakhala ndi hygroscopic katundu, monga kusungidwa m'malo okhala ndi chinyezi chachikulu, caking idzachitika.Zotsukira zotsekemera ndizovuta kwambiri kugwiritsa ntchito.The hexahydrate wopangidwa ndi sodium tripolyphosphate pambuyo kuyamwa madzi ali ndi makhalidwe youma.Pakakhala kuchuluka kwa sodium tripolyphosphate mu chotsukira chilinganizo, zingalepheretse caking chodabwitsa chifukwa mayamwidwe chinyezi ndi kusunga youma ndi granular mawonekedwe a zotsukira kupanga.
2. Kuyeretsa madzi ndi kufewetsa: sodium tripolyphosphate chelates zitsulo zitsulo ndi ayoni zitsulo mu njira Ca2+, Mg2+, Cu2+, Fe2+, etc., kupanga chelates sungunuka, potero kuchepetsa kuuma, ndipo chimagwiritsidwa ntchito poyeretsa madzi ndi kufewetsa.
3. Chofewetsa peel: pangani masamba ndi zipatso peel kuti zifewetse mwachangu, chepetsani nthawi yophika ndikuwonjezera kuchuluka kwa pectin.
4. Anti-discoloration agent, preservative: ikhoza kulimbikitsa kuwonongeka kwa vitamini C ndi kutayika kwa mtundu, kusinthika, kungalepheretse nyama, nkhuku, ziphuphu za nsomba, kuti ziwonjezere nthawi yosungiramo chakudya.
5. Bleaching woteteza wothandizila, deodorant: kusintha blekning zotsatira, ndipo akhoza kuchotsa fungo mu ayoni zitsulo.
6. Antiseptic ndi bacteriostatic wothandizila: ziletsa kukula kwa tizilombo tating'onoting'ono, choncho amachita antiseptic ndi bacteriostatic udindo.
7. Emulsifier, pigment mincemeat dispersant, anti-delamination agent, thickening agent: kumwaza kapena kukhazikika kuyimitsidwa kwa zinthu zosasungunuka m'madzi kuti ateteze kumamatira ndi kuyimitsidwa kwa kuyimitsidwa.
8. Chotchinga champhamvu ndi choteteza: Kuwongolera ndi kusunga PH yosasunthika, zomwe zingapangitse kuti chakudya chizikoma kwambiri.Kuwongolera acidity, kuchuluka kwa asidi.
9. Madzi posungira wothandizira, kufewetsa wothandizira, tenderizing wothandizira: ali ndi mphamvu kumatheka pa mapuloteni ndi globulin, kotero akhoza kuonjezera hydration ndi madzi posungira nyama nyama, kusintha malowedwe a madzi, kulimbikitsa kufewetsa chakudya ndi kusintha khalidwe. chakudya, ndi kusunga kukoma kwabwino kwa chakudya.
10. Anti-agglutination agent: Mu mkaka, amatha kuletsa kusungunuka kwa mkaka pamene akuwotcha, ndikuletsa kulekana kwa mapuloteni a mkaka ndi madzi a mafuta.
11. Utoto, kaolin, magnesium okusayidi, calcium carbonate ndi mafakitale ena kukonzekera kuyimitsidwa monga dispersant.
12. Kuyaya AIDS.
13. Kubowola matope dispersants.
14. Makampani opanga mapepala omwe amagwiritsidwa ntchito ngati anti-oil agent.
15. Monga wothandizira degumming mu kupanga ceramic.
16. Wowotchera zikopa.
17. Industrial boiler madzi kufewetsa wothandizira.
