I-Hydroxypropylmethylcellulose kunye nonyango lwe-Surface HPMC

Hydroxypropylmethylcellulose(HPMC) yipolymer esekwe kwiselulosi esetyenziswa kakhulu kumayeza, ukutya, kunye namashishini okuthambisa. Ingumgubo omhlophe okanye omhlophe oxutywe emanzini kwaye wenze isisombululo esicacileyo, esibonakalayo. I-HPMC isetyenziswa njenge-thickener, emulsifier, kunye ne-stabilizer kwiimveliso ezahlukeneyo. Ikwasetyenziswa njenge-ejenti yokugquma iipilisi kunye nee-capsules.

Unyango lomphezulu lwe-HPMC lubandakanya ukuguqula iipropati zomphezulu wepolymer ukunyusa ukusebenza kwayo. Unyango lomphezulu lunokuphucula ukuncamathela, ukumanzisa, kunye nokusasazeka kwe-HPMC. Kwakhona kunokuphucula ukuhambelana kwe-HPMC kunye nezinye izithako ekuqulunqweni.

Ezinye iindlela eziqhelekileyo zonyango lwe-HPMC ziquka:

1. I-Etherification: Oku kubandakanya ukusabela kwe-HPMC kunye ne-alkylating agent ukwazisa amaqela ongezelelweyo e-hydrophobic kumphezulu wepolymer.

2. Cross-linking: Oku kubandakanya ukwazisa i-cross-links phakathi kwee-molecule ze-HPMC ukwandisa amandla kunye nokuzinza kwepolymer.

3. I-Acetylation: Oku kubandakanya ukwazisa amaqela e-acetyl kumphezulu we-HPMC ukwandisa ukunyibilika kunye nokuzinza.

4. I-Sulfonic: Oku kubandakanya ukwazisa amaqela e-sulfonic acid kumphezulu we-HPMC ukuphucula ukunyibilika kwamanzi kunye ne-dispersibility.

Ngokubanzi, unyango olungaphezulu lwe-HPMC lunokuphucula ukusebenza kwayo kwaye luyenze ifaneleke ngakumbi kuluhlu olubanzi lwezicelo.
