Zvemakemikari zvivakwa
Sodium Stearate ipfuhwe chena, zvishoma svutugadzike mumvura inotonhora, uye nekukurumidza mumvura inopisa, uye haina kuchema mushure mekudzora mumhinduro yakadzika sipo. Ane simba rakanakisa, rinopinza uye rinosimbisa simba, rine mafuta anonzwa, uye ane kunhuhwirira kwakakora. Iyo inochema mumvura inopisa kana mvura inodhaka, uye mhinduro iri alkaline nekuda kwehydrolysis.
Application
Mashandisiro anoshandiswa eSodium Stearate: Thickener; emulsifier; kupararira; kunamatira; Corrosion Inhibitor 1. Destagent: yakashandiswa kudzora foam panguva yekukanda.
2.
3. Corrosion Inhibitor: Iyo ine zvivakwa zvekudzivirira mune cluster packating firimu.
4.
5. Kunamatira: Inoshandiswa seyakasikwa glue kuAnta pepa.
Tsananguro
Sodium Stearate ndiyo sodium munyu weStedic Acid, zvakare inozivikanwa seSodium Octivecate, iyo inowanzo shandiswa inoshandiswa siractitant uye chikamu chikuru chemasapu. Iyo hydrocarbyl inoshamisira mumugodhi weSodium Stearate ndeye hydrophobic Boka, uye iyo carboxyl modion iboka hydrophilic. Mumvura soapy, sodium stearate iripo mumicelle. Iwo micelle anotenderera uye anoumbwa nemamorekuru mazhinji. Mapoka eHydrophobic ari mukati uye akasanganiswa nemumwe nemumwe naVan Der Waals mauto, uye mapoka emhystempililililic ari kunze uye akagoverwa pamusoro pemachira. Micellles akapararira mumvura, uye pavanosangana nemafuta emafuta emvura, iwo mafuta anogona kuparadzirwa mumadonhwe akanaka emakonzo. Iyo hydrophobic boka reSodium Stearate rinopera mumafuta, nepo hydrophic boka rakamiswa mumvura yekushambidzika. Mumvura yakaoma, steatate ion inosanganiswa neCalcium uye Maganium Ions kuti aumbe mvura-insoluble calcium uye magnunium mapundu, achideredza fungidziro. Pamusoro peSodium Stearate, Soap zvakare ine Sodium Palmitate Ch3 (Ch2) 14Coona uye Sodium Salts yedzimwe Fatty Acids (C12-c22-c20).
