I-Cosmetcs Grade Y-polyglutamic acid

I-γ-polyglutamic acid (γ-polyglutamic acid, ebizwa ngokuthi γ-PGA) nge-L-glutamic acid ngokwakhiwa kwe-γ-amide bond ye-poly amino acid compounds, i-microbial Bacillus subtilis fermentation ukuze yakhe i-anionic polymer encibilika emanzini. .Inoncibilika kahle emanzini, imunca kahle kakhulu kanye ne-biodegradability.Umkhiqizo wokucekela phansi i-glutamic acid engangcoli.Ingasetshenziswa njenge-ejenti yokugcina amanzi, i-heavy metal ion adsorbent, i-flocculant, i-ejenti yokukhululwa okuqhubekayo kanye nenkampani yezidakamizwa, njll. Isetshenziswa kabanzi ekutshaleni kwezolimo, ukwelashwa kwenhlabathi, ukuvikelwa kwemvelo, ukudla, imithi, izimonyo nezinye izimboni.

Izici zomkhiqizo

Ukugcinwa kwamanzi e-Hydrophilic: i-polyglutamic acid ingakwazi ukumunca izikhathi ezingu-1500 zama-molecule wamanzi, igcine amanzi nezakhamzimba ekusabalaliseni okusebenzayo kwenhlabathi, ikhuthaze ukumuncwa kwezitshalo, inciphise ukuhwamuka kwamanzi nokuvuza, futhi ingavimbela ukubola ngokushesha nokulahlekelwa izingxenye zamanzi nomanyolo, ukunciphisa ngokuqondile inani likamanyolo kanye nokufakwa kwamanzi okungaphezu kwama-20%.

Ukonga umanyolo nokusebenza kahle kuyanda: Iketango elide le-PGA linenombolo enkulu yamaqembu amahhala e-negative carboxyl kagesi, enamandla okukhangisa ama-ion anomsoco.Umthamo wayo wokukhanga nokushintshanisa cishe uphindwe izikhathi eziyikhulu kunenhlabathi yemvelo, enciphisa ukucwiliswa kwezakhi kanye nokuguquguquka, inothisa imisoco emaphakathi nencane njenge-N, P, K, Ca kanye ne-Mg, futhi ithuthukisa umthamo wokunikeza izakhi zomhlabathi.

Ukuthuthukiswa komhlabathi: kuthuthukisa ukugcineka kwamanzi, ukungena kwamanzi kanye nokungena komoya kwenhlabathi.Ngasikhathi sinye, i-polyglutamic acid iqukethe inqwaba yamaqembu e-carboxyl namaqembu e-amino, angavimba ushintsho lwe-acid-base olubangelwa ama-ion e-hydrogen nama-ion we-hydroxide, alinganise inani le-acid-base yenhlabathi, futhi agweme ikhwalithi yomhlabathi ene-asidi nomhlabathi. ukwakheka kwamapuleti okubangelwa ukusetshenziswa isikhathi eside komanyolo wamakhemikhali.

Thuthukisa ukubekezelela ukucindezeleka: i-polyglutamate ingakhuthaza ukukhula kwezinwele zezimpande zezitshalo nokukhula kwezimpande, ngaleyo ndlela ithuthukise ikhono lempande lokumunca izakhi.Endaweni yesomiso nezikhukhula kanye nezinga lokushisa eliphansi, kungaqinisekisa ngempumelelo ukumuncwa okujwayelekile kwamanzi nezakhamzimba.
