I-Cosmetcs yeBanga le-Y-polyglutamic acid

I-γ-polyglutamic acid (γ-polyglutamic acid, ekubhekiselwa kuyo njenge-γ-PGA) nge-L-glutamic acid ngokusekwa kwe-γ-amide bond ye-poly amino acid compounds, yi-microbial Bacillus subtilis fermentation ukwenza i-polymer anionic enyibilikayo emanzini. .Inonyibiliko olugqwesileyo emanzini, i-super absorbability kunye ne-biodegradability.Imveliso yokuthotywa i-glutamic acid engangcolisekiyo.Ingasetyenziswa njenge-arhente yokugcina amanzi, i-ion adsorbent yensimbi enzima, i-flocculant, i-arhente yokukhululwa eqhubekayo kunye nomphathi weziyobisi, njl. Isetyenziselwa kakhulu ukutyala kwezolimo, unyango lomhlaba, ukhuseleko lokusingqongileyo, ukutya, amayeza, izithambiso kunye namanye amashishini.

Ubume bemveliso

Iimpawu zemveliso

Ukugcinwa kwamanzi e-Hydrophilic: i-polyglutamic acid inokuzifunxa ngokwawo amaxesha angama-1500 eemolekyuli zamanzi, igcine amanzi kunye nezondlo ekusasazeni okusebenzayo komhlaba, ikhuthaze ukufunxwa kwezityalo, inciphise ukuvela komphunga kunye nokuvuza kwamanzi, kwaye inokuthintela ukubola okukhawulezayo kunye nokulahleka kwamanzi kunye nezixhobo zesichumisi, ukunciphisa ngokuthe ngqo ubungakanani bezichumisi kunye nokufakwa kwamanzi ngaphezu kwe-20%.

Ukonga izichumiso kunye nokusebenza kakuhle okukhulayo: Itsheyini elide le-PGA linenani elikhulu lamaqela asimahla e-carboxyl yombane, enomthamo owomeleleyo we-adsorption yeeyoni zezakhamzimba.I-adsorption yayo kunye nomthamo wokutshintshiselana malunga ne-100 ngokuphindwe nge-100 yomhlaba wendalo, onciphisa ukuvuza kwezondlo kunye nokuguquguquka, ukutyebisa izondlo eziphakathi kunye ne-micro ezifana ne-N, P, K, Ca kunye ne-Mg, kwaye iphucula umthamo wokubonelela ngezondlo zomhlaba.

Ukuphuculwa komhlaba: kuphucula ukugcinwa kwamanzi, ukungena kwamanzi kunye nokungena komoya emhlabeni.Kwangelo xesha, i-polyglutamic acid iqulethe inani elikhulu lamaqela e-carboxyl kunye namaqela e-amino, anokuthintela utshintsho lwe-asidi-base ebangelwa yi-hydrogen ion kunye ne-hydroxide ion, ibhalansi ixabiso lesiseko se-asidi yomhlaba, kwaye iphephe umgangatho womhlaba we-asidi kunye nomhlaba. ukubunjwa kwepleyiti okubangelwa kukusetyenziswa kwexesha elide kwezichumisi zekhemikhali.

Ukuphucula ukunyamezela koxinzelelo: i-polyglutamate inokukhuthaza ukukhula kweenwele zeengcambu zesityalo kunye nokukhula kweengcambu, ngaloo ndlela kuphuculwe amandla eengcambu zokufumana izondlo.Kwimekobume yembalela kunye nezikhukhula kunye nobushushu obuphantsi, inokuqinisekisa ngokufanelekileyo ukufunxa okuqhelekileyo kwamanzi kunye nezondlo.
