Iselulosi, i-hydroxyethyl ether (MW 1000000)

Iselulosi, i-hydroxyethyl ether (MW 1000000)

Iselulosi yeHydroxyethyl(HEC) i-polymer e-soluble yamanzi ephuma kwi-cellulose ngokusungulwa kwamaqela e-hydroxyethyl. Ubunzima bemolekyuli (MW) obucacisiweyo, 1000000, bumele umahluko ophakamileyo wobunzima bemolekyuli. Nantsi isishwankathelo se-hydroxyethyl cellulose enobunzima bemolekyuli ye-1000000:

I-Hydroxyethyl Cellulose (HEC):

  1. Ulwakhiwo lweMichiza:
    • I-HEC yi-cellulose derivative apho amaqela e-hydroxyethyl afakwe kwiiyunithi ze-anhydroglucose zekhonkco le-cellulose. Olu hlengahlengiso luphucula ukunyibilika kwamanzi kunye nezinye iimpawu ezisebenzayo zeselulosi.
  2. Ubunzima beMolekyuli:
    • Ubunzima bemolekyuli obuchaziweyo be-1000000 bubonisa umahluko ophakamileyo wobunzima bemolekyuli. Ubunzima bemolekyuli buchaphazela i-viscosity, iimpawu ze-rheological, kunye nokusebenza kwe-HEC kwizicelo ezahlukeneyo.
  3. Ifomu yoMzimba:
    • I-Hydroxyethyl cellulose enobunzima bemolekyuli ye-1000000 ngokuqhelekileyo ifumaneka ngendlela yomgubo omhlophe ukuya kumhlophe, ongenavumba. Isenokunikezelwa njengesisombululo solwelo okanye ukusasazwa.
  4. Ukunyibilika kwamanzi:
    • I-HEC i-soluble yamanzi kwaye inokwenza izisombululo ezicacileyo kunye ne-viscous emanzini. Iqondo lokunyibilika kunye ne-viscosity inokuphenjelelwa zizinto ezifana nobushushu, i-pH, kunye nokugxila.
  5. Usetyenziso:
    • I-Agent yokutyebisa: I-HEC isetyenziswa ngokuqhelekileyo njenge-ejenti yokuqina kwizicelo ezahlukeneyo, kubandakanywa iipeyinti, iingubo, i-adhesives, kunye neemveliso zokhathalelo lomntu. Ukwahluka kobunzima bemolekyuli obuphezulu busebenza ngokukodwa ekuboneleleni nge-viscosity.
    • I-Stabilizer: Isebenza njenge-stabilizer kwi-emulsions kunye nokumiswa, igalelo ekuzinzeni nasekufaniseni ukwakheka.
    • I-Agent yokugcinwa kwamanzi: I-HEC ineempawu ezigqwesileyo zokugcina amanzi, okwenza ukuba axabiseke kwizinto zokwakha, ezifana nodaka kunye neemveliso ezenziwe ngesamente.
    • Amachiza: Kwishishini lamachiza, i-HEC isetyenziswa njenge-binder, i-disintegrant, kunye ne-thickener kwi-tablet formulations. Ubume bayo bokunyibilika kwamanzi buyenza ifaneleke kwiifom ezahlukeneyo zedosi yomlomo.
    • IiMveliso zoNakekelo loMntu: Ifunyenwe kwii-cosmetics, i-shampoos, kunye ne-lotions, i-HEC ibonelela nge-viscosity kunye nokuzinza ekuqulunqweni kwishishini lokunyamekela.
    • Ishishini leoli kunye neGesi: I-HEC isetyenziselwa ukugrumba amanzi njenge-rheology modifier kunye ne-arhente yokulawula ilahleko.
  6. Ulawulo lweViscosity:
    • Ubunzima be-molecular of HEC bunegalelo ekusebenzeni kwayo ekulawuleni i-viscosity. Le propati ixabisekile kwizicelo apho ubukhulu obufunwayo okanye iimpawu zokuhamba kwemveliso kufuneka zigcinwe.
  7. Ukuhambelana:
    • I-HEC ngokubanzi iyahambelana noluhlu olubanzi lwezinye izinto kunye nezongezo ezisetyenziswa ngokuqhelekileyo kumashishini ahlukeneyo. Nangona kunjalo, uvavanyo lokuhambelana kufuneka luqhutywe xa kuqulunqwa ngamacandelo athile.
  8. ImiGangatho yoMgangatho:
    • Abavelisi bahlala bebonelela ngemigangatho kunye nemigangatho yomgangatho weemveliso ze-HEC, ukuqinisekisa ukuhambelana nokuthembeka ekusebenzeni. Le migangatho inokubandakanya iikhrayitheriya ezinxulumene nobunzima bemolekyuli, ubunyulu, kunye nezinye iipropathi ezifanelekileyo.

I-Hydroxyethyl cellulose enobunzima bemolekyuli ye-1000000 yipolymer eguquguqukayo enezicelo ezahlukeneyo kuwo wonke amashishini, ngakumbi kwimiqulu apho i-viscosity ephezulu kunye nokunyibilika kwamanzi ziimpawu ezibalulekileyo. Kubalulekile ukulandela izikhokelo ezicetyiswayo kunye nokwakheka okubonelelwa ngabavelisi ngeziphumo ezigqwesileyo kwizicelo ezithile.
