Uluhlu lwezixhobo zematrix kwiimveliso zokhathalelo lwesikhumba (2)

Kwiveki ephelileyo, sithethe ngezinto ezisekwe kwi-oyile kunye nomgubo kwizinto zokuthambisa zematrix. Namhlanje, siya kuqhubeka nokuchaza izinto eziseleyo ze-matrix: izixhobo zegum kunye nezixhobo zokunyibilikisa.

Izinto eziluhlaza ze-Colloidal - abagcini be-viscosity kunye nokuzinza
Imathiriyeli ekrwada yeGlial ziikhompawundi zepolymer ezinyibilikayo emanzini. Uninzi lwezi zinto zinokukhula zibe yicolloid emanzini ukwenza intonga eqinileyo yomgubo. Zisenokusetyenziswa njengeemulsifiers ukuzinzisa emulsions okanye ukumiswa. Ukongeza, banokwenza iifilimu kwaye batyebe ijeli. Iimathiriyeli ekrwada yeglial esetyenziswa kwizithambiso zohlulwe kakhulu zibe ziindidi ezintathu: ezendalo kunye nezokwenziwa, kunye ne-semisynthetic.

I-polymer compounds yendalo e-soluble yamanzi: ngokuqhelekileyo ivela kwizityalo okanye kwizilwanyana, ezifana nesitashi, i-gum yezityalo (ezifana ne-Arabic gum), i-gelatin yezilwanyana, njl.

I-synthetic water-soluble polymer compounds, kuquka i-polyvinyl alcohol, i-polyvinylpyrrolidone, i-polyacrylic acid, njl., inezakhiwo ezizinzileyo, ukucaphuka kwesikhumba esincinci, kunye namaxabiso aphantsi, ngaloo ndlela ithatha indawo yendalo ye-polymer e-soluble yamanzi njengomthombo oyintloko we-colloidal materials. Ihlala isetyenziswa njenge-adhesive, thickener, agent-forming agent, kunye ne-emulsifying stabilizer kwi-cosmetics.

Iikhompawundi ze-polymer ze-semi synthetic ezinyibilikayo zamanzi: Ezona ziqhelekileyo ziquka i-methyl cellulose, i-ethyl cellulose, i-carboxymethyl cellulose i-sodium hydroxyethyl cellulose, i-guar gum kunye ne-derivatives yayo, njl.

Izinto ezinyibilikayo ekrwada - isitshixo sokunyibilika nokuzinza

Imathiriyeli ekrwada yokunyibilikisa zizinto ezibalulekileyo kulwelo oluninzi, intlama, kunye nokuncamathelisa iifomyula zokhathalelo lwesikhumba. Xa zidibene nezinye izithako kwifomula, zigcina iimpawu ezithile zomzimba zemveliso. Izinto ezisetyenziswa ngokuqhelekileyo ze-solvent kwi-cosmetics zibandakanya amanzi, i-ethanol, i-isopropanol, i-n-butanol, i-ethyl acetate, njl.
