Sodium Tripolyphosphate (STPP)

piav qhia luv luv:

Sodium tripolyphosphate yog ib qho inorganic compound uas muaj peb pawg phosphate hydroxyl (PO3H) thiab ob pawg phosphate hydroxyl (PO4).Nws yog dawb los yog daj, iab, soluble nyob rau hauv dej, alkaline nyob rau hauv aqueous tov, thiab tso tawm ntau tshav kub thaum yaj nyob rau hauv acid thiab ammonium sulfate.Thaum kub kub, nws tawg mus rau hauv cov khoom xws li sodium hypophosphite (Na2HPO4) thiab sodium phosphite (NaPO3).

Cov ntsiab lus ≥ 85% / 90% / 95%

Sodium tripolyphosphate anhydrous tshuaj tuaj yeem muab faib ua hom kub kub (I) thiab qis kub hom (II).Cov tshuaj aqueous yog qaug zog alkaline, thiab pH ntawm 1% aqueous tov yog 9.7.Hauv cov tshuaj aqueous, pyrophosphate lossis orthophosphate yog maj mam hydrolyzed.Nws tuaj yeem sib xyaw alkaline ntiaj teb hlau thiab hnyav hlau ions kom muag dej zoo.Nws kuj tseem muaj peev xwm hloov pauv ion uas tuaj yeem hloov qhov kev ncua mus rau hauv kev daws teeb meem loj heev.Hom I hydrolysis sai dua li hom II hydrolysis, yog li hom II tseem hu ua qeeb hydrolysis.Ntawm 417 ° C, hom II hloov mus rau hom I.

Na5P3O10·6H2O yog triclinic ncaj lub kaum sab xis dawb prismatic siv lead ua, tiv taus huab cua, nrog tus nqi txheeb ze ntawm 1.786.Melting point 53 ℃, soluble hauv dej.Cov khoom tawg thaum lub sij hawm recrystallization.Txawm hais tias nws raug kaw, nws tuaj yeem decompose rau hauv sodium diphosphate ntawm chav tsev kub.Thaum rhuab mus rau 100 ° C, qhov teeb meem decomposition ua sodium diphosphate thiab sodium protophosphate.

Qhov txawv yog tias daim ntawv cog lus ntev thiab daim ntawv cog lus lub kaum sab xis ntawm ob qhov sib txawv, thiab cov khoom siv tshuaj lom neeg ntawm ob yog tib yam, tab sis qhov thermal stability thiab hygroscopicity ntawm hom I yog siab dua li hom II.

Khoom siv

Kev ntxuav txhua hnub

Nws yog tsuas yog siv los ua ib qho kev pabcuam rau cov khoom siv hluavtaws, xab npum synergist thiab tiv thaiv cov xab npum roj los nag thiab frosting.Nws muaj zog emulsification nyhuv ntawm lubricating roj thiab roj, thiab yuav siv tau raws li ib tug leavening neeg sawv cev.Nws tuaj yeem txhim kho lub peev xwm decontamination ntawm xab npum thiab txo qhov kev puas tsuaj ntawm stains rau ntaub.Tus nqi PH ntawm cov xab npum tsis tuaj yeem hloov kho kom zoo dua qub.

Bleach/deodorant/antibacterial agent

Nws tuaj yeem txhim kho cov nyhuv bleaching, thiab tuaj yeem tshem tawm cov ntxhiab ntawm cov hlau ions, thiaj li siv tau rau hauv cov tshuaj dawb deodorant.Nws tuaj yeem cuam tshuam kev loj hlob ntawm cov kab mob microorganisms, yog li ua lub luag haujlwm tiv thaiv kab mob.

Tus neeg saib xyuas dej;Chelating tus neeg sawv cev;Emulsifier (Food Qib)

Nws yog dav siv hauv cov khoom noj, feem ntau siv rau hauv cov khoom noj nqaij, dej haus, khoom noj siv mis, pastries thiab lwm yam khoom noj.Piv txwv li, ntxiv sodium tripolyphosphate rau cov khoom noj nqaij xws li nqaij npua thiab hnyuv ntxwm tuaj yeem ua rau kom cov viscosity thiab elasticity ntawm cov khoom nqaij, ua rau cov khoom noj nqaij ntau qab.Ntxiv sodium tripolyphosphate rau cov kua txiv hmab txiv ntoo tuaj yeem ua kom nws ruaj khov thiab tiv thaiv nws cov delamination, nag lossis daus thiab lwm yam tshwm sim.Feem ntau, lub luag haujlwm tseem ceeb ntawm sodium tripolyphosphate yog txhawm rau txhim kho kev ruaj ntseg, viscosity thiab saj ntawm cov zaub mov, thiab txhim kho qhov zoo thiab saj ntawm cov zaub mov.

① Ua kom muaj viscosity: sodium tripolyphosphate tuaj yeem ua ke nrog cov dej molecules los tsim cov colloids, yog li ua kom cov viscosity ntawm cov zaub mov thiab ua kom nws ntom.

② Kev ruaj ntseg: Sodium tripolyphosphate tuaj yeem ua ke nrog cov protein kom tsim cov khoom ruaj khov, yog li txhim kho kev ruaj ntseg ntawm cov zaub mov thiab tiv thaiv stratification thiab nag lossis daus thaum lub sijhawm tsim khoom thiab khaws cia.

③ Txhim kho qhov saj: sodium tripolyphosphate tuaj yeem txhim kho qhov saj thiab kev ntxhib los mos ntawm cov khoom noj, ua kom nws muag muag, du, nplua nuj saj.

④ yog ib qho ntawm cov khoom siv dej khaws cia hauv cov nqaij ua cov nqaij, muaj cov nyhuv adhesion muaj zog, tuaj yeem tiv thaiv cov khoom nqaij los ntawm kev puas tsuaj, deterioration, dispersion, thiab tseem muaj zog emulsification nyhuv ntawm cov roj.Cov khoom siv nqaij ntxiv nrog sodium tripolyphosphate poob dej tsawg dua tom qab cua sov, cov khoom tiav tiav, cov xim zoo, cov nqaij yog kev sib tw, yooj yim rau hlais, thiab txiav nto yog ci.

Kev kho dej softening

Kev lim dej thiab muag muag: sodium tripolyphosphate thiab hlau ions hauv cov tshuaj Ca2+, Mg2+, Cu2+, Fe2+ thiab lwm yam hlau ions chelate los tsim cov chelates soluble, yog li txo cov hardness, yog li dav siv hauv dej purification thiab softening.
