Sodium carboxymethylcellulose malamalama

O le Sodium carboxymethylcellulose (NaCMC) o se mea faʻapitoa ma faʻaogaina cellulose e maua ai le faʻaogaina i pisinisi eseese ona o ona uiga tulaga ese. O lenei tuufaatasiga e maua mai i le cellulose, o se polymer faanatura o loʻo maua i puipui sela o laʻau. O le sodium carboxymethyl cellulose o loʻo faʻapipiʻiina e ala i le taliina o le cellulose ma le sodium monochloroacetate ma faʻamalo. O oloa e maua mai e maua ai le tele o mea e mana'omia, e fa'atauaina ai mea'ai ma meainu, vaila'au, mea teuteu, ie ma isi mea.

Fauga ma fatuga:

Sodium carboxymethyl cellulose o se polymer solu vai ma se fausaga laina. O le cellulose backbone ua suia e vaega carboxymethyl na faʻafeiloaʻi e le etherification. O le tikeri o le suitulaga (DS) e faasino i le averesi numera o vaega carboxymethyl i iunite anhydroglucose i le filifili cellulose. O le DS e matua a'afia ai mea fa'aletino ma vaila'au o le NaCMC.

Fa'agasologa o le gaosiga:

O le gaosiga o le sodium carboxymethylcellulose e aofia ai ni laasaga. O le cellulose e masani lava ona maua mai le pulupulu laupapa poʻo le cotton ma e muaʻi togafitia e aveese ai mea leaga. Ona tali atu lea i le sodium monochloroacetate i lalo o tulaga alkaline e faʻafeiloaʻi ai le vaega carboxymethyl. O le mea e maua ai e fa'agataina ina ia maua ai le masima masima o le carboxymethylcellulose.

Amioga fa'aletino ma kemisi:

Solubility: NaCMC e sili ona solu i le vai, fausia se vaifofo manino ma viscous. O lenei solubility o se uiga autu mo lona faʻaaogaina lautele i pisinisi eseese.

Viscosity: O le viscosity o le sodium carboxymethylcellulose solution e mafai ona fetuunai e ala i le puleaina o le maualuga o le sui ma le faʻatonuga. O lenei meatotino e talafeagai mo talosaga e manaʻomia ai le mafiafia poʻo le gelling.

Tulaga mautu: NaCMC tumau mautu i luga o le lautele lautele pH, lea e faʻaleleia ai lona agavaʻa i faʻasologa eseese.

Ata-fausia: O loʻo i ai mea faʻapipiʻi ata ma e mafai ona faʻaaogaina e gaosia ai ata tifaga ma faʻapipiʻi i ni faʻaoga eseese.

talosaga:

Alamanuia o Mea'ai ma Meainu:

Su'i fa'afefete:NaCMC e masani ona faʻaaogaina e fai ma sui mafiafia i meaʻai e pei o sosi, laʻei ma meainu.

Stabilizer: E tuifa'afefeteina emulsions ma taofiga i oloa e pei ole aisakulimi ma salati dressings.

Fa'alelei a'e: NaCMC e tuʻuina atu mea e manaʻomia i meaʻai, faʻaleleia atili le lelei.fualaau faasaina:

Fa'amau: Fa'aaogainae fai ma fusifusia i totonu o fuala'au papa'a e fa'amautinoa ai le sa'o lelei o le fausaga o papa.

Suiga viscosity: fetuutuunai le visfua ole vai e fesoasoani ile tu'uina atu ole vaila'au.

Mea teuteu ma tausiga a le tagata lava ia:

Stabilizers: Fa'aaoga e fa'amautu ai emulsion i kulimi ma lotions.
Mea mafiafia: Fa'ateleina le viscosity o le shampoo, pa'u fulunifo ma isi mea e teu ai le tagata lava ia.
ie:

Sizing agent: faʻaaogaina mo le faʻavasegaina o ie e faʻaleleia ai le malosi ma le lamolemole o alava i le taimi o le lalagaina.

Fa'apipi'i lolomi: E fai ma fa'amalo ma fa'afou fa'aliliu i le pa'u lomi ie.
Alamanuia Suau'u ma Kasa:

Suavai vili: NaCMC ofa'aaogaina e fai ma tackifier i le viliina o vai e fa'aleleia ai ana mea fa'a-rheological.

Alamanuia pepa:

Su'e fa'apipi'i: fa'aoga mo le fa'apipi'iina o pepa e fa'aleleia ai meatotino i luga.
isi pisinisi:

Togafitiga o Suavai: Faʻaaogaina i faiga faʻafefe vai ona o ona uiga faʻafefe.

Lafoa'i: E fai ma fa'amautu i nisi o mea fa'amama.

Saogalemu ma tulafono faatonutonu:

Sodium carboxymethylcellulose e masani ona iloa o se saogalemu (GRAS) mo le faʻaaogaina i meaʻai ma vailaʻau. O loʻo tausisia tulaga faʻatonutonu ma faʻamatalaga faʻatulagaina e le tele o lala sooupu, e aofia ai le US Food and Drug Administration (FDA) ma le European Food Safety Authority (EFSA).

Sodium carboxymethyl cellulose o se polymer multifunctional ma le tele o faʻaoga i pisinisi eseese. O lona tu'ufa'atasiga tulaga ese o le solubility, viscosity pulea, mautu ma ata-fausia meatotino e avea o se elemene taua i le tele o formulations. Aʻo faʻaauau pea ona faʻaleleia le alamanuia, o le manaʻoga mo sodium carboxymethylcellulose e ono faʻaauau ona o lona faʻaogaina ma le sao i le faʻaleleia atili o le gaosiga o oloa i le tele o talosaga.
