KHOOM NTAUB NTAWV
Sodium tripolyphosphate anhydrous tshuaj tuaj yeem muab faib ua hom kub kub (I) thiab qis kub hom (II).Dawb crystalline hmoov los yog crystalline hmoov.Tus txheeb ze molecular hnyav yog 367.86, tus txheeb ze ntom yog 2.49, thiab lub melting point yog 662 ℃.Soluble hauv dej (14.5g / 100g ntawm 25 ℃, 23.25g / 100g ntawm 80 ℃).Cov tshuaj aqueous yog qaug zog alkaline, thiab pH ntawm 1% aqueous tov yog 9.7.Hauv cov kua dej aqueous, pyrophosphate lossis orthophosphate yog maj mam hydrolyzed.Nws tuaj yeem ua cov alkaline ntiaj teb hlau thiab hnyav hlau ions, softening 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 hom II, yog li hom II tseem hu ua qeeb hydrolysis.Ntawm 417 ℃, hom II hloov mus rau hauv hom I. Na5P3O10·6H2O hexahydrate yog triclinic orthomeric dawb prismatic siv lead ua nrog huab cua muaj peev xwm thiab tus nqi txheeb ze ntawm 1.786.Melting point 53 ℃, soluble hauv dej.Cov khoom no tuaj yeem decomposed thaum recrystallization.Txawm hais tias nws raug kaw, nws tuaj yeem decomposed rau hauv sodium diphosphate ntawm chav tsev kub.Thaum rhuab mus rau 100 ℃, qhov teeb meem decomposition ua sodium diphosphate thiab sodium thawj phosphate.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
QIB INDUSTRIAL
Tshuaj ntxuav tes
Nws yog tsuas yog siv los ua ib qho kev pabcuam rau cov khoom siv hluavtaws, ua cov xab npum synergist thiab tiv thaiv cov roj los nag thiab frosting ntawm cov xab npum bar.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 ntawm cov ntaub.Nws tuaj yeem siv los kho tus nqi PH ntawm cov xab npum tsis zoo thiab txhim kho kev ntxuav kom zoo.
Dej softener
Kev lim dej thiab cov tshuaj softener: sodium tripolyphosphate chelates hlau ions nrog hlau ions hauv kev daws Ca2+, Mg2+, Cu2+, Fe2+, thiab lwm yam, los tsim cov chelates soluble, yog li txo qhov hardness, yog li nws yog dav siv hauv dej purification thiab softening.
Bleach deodorant bacteriostatic tus neeg sawv cev
Cov nyhuv bleaching tuaj yeem txhim kho, thiab cov ntxhiab ntawm cov hlau ions tuaj yeem raug tshem tawm, yog li siv cov tshuaj dawb deodorants.Nws tuaj yeem cuam tshuam kev loj hlob ntawm cov kab mob thiab yog li ua lub luag haujlwm bacteriostatic.
QHOV TSEEB
Tus neeg saib xyuas dej;Chelating tus neeg sawv cev;emulsifier
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 nqaij cov khoom xws li nqaij npua thiab hnyuv ntxwm tuaj yeem ua rau lawv cov viscosity thiab elasticity, ua rau lawv qab dua.Ntxiv sodium tripolyphosphate rau kua txiv thiab dej haus tuaj yeem ua rau 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.
①Increase 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.
②Stability: Sodium tripolyphosphate tuaj yeem ua ke nrog cov protein kom tsim cov khoom ruaj khov, yog li txhim kho cov khoom noj khoom haus ruaj khov thiab tiv thaiv stratification thiab nag lossis daus thaum lub sijhawm tsim khoom thiab khaws cia.
③ Txhim kho kev ntxhib los mos thiab saj: sodium tripolyphosphate tuaj yeem txhim kho kev ntxhib los mos thiab saj ntawm cov zaub mov, ua rau nws muag muag, du, nplua nuj saj.
④ Ib qho ntawm cov dej tuav cov neeg ua haujlwm feem ntau siv hauv kev ua cov nqaij, nws muaj cov nplaum nplaum zoo, thiab tuaj yeem tiv thaiv kom tsis muaj xim, deterioration thiab dispersion ntawm cov khoom nqaij, thiab tseem muaj zog emulsification ntawm cov roj.Cov khoom siv nqaij nrog sodium tripolyphosphate ntxiv muaj dej tsawg dua tom qab cua sov, thiab cov khoom tiav tiav, cov xim zoo, cov nqaij sib tw, yooj yim rau hlais, thiab ci ntsa iab.
