Ibanga lemihla ngemihla imichiza ye-hydroxypropyl methylcellulose HPMC

I-Hydroxypropyl methylcellulose yi-ether ye-cellulose engekho i-ionic eyenziwe kwizinto ze-polymer zendalo (ikotoni) i-cellulose ngokusebenzisa uchungechunge lweenkqubo zemichiza. Ngumgubo omhlophe ongenavumba, ongenancasa odumba ube yicolloidal ecacileyo okanye enamafu kancinane kumanzi abandayo. Inokuqina, ukubopha, ukusabalalisa, i-emulsifying, ifilimu-ifom, ukumisa, i-adsorbing, i-gelling, i-surface esebenzayo, igcina umswakama kunye neempawu ze-colloid ezikhuselayo.

Iimpawu kunye nezinto eziluncedo mihla le grade khemikhali cellulose HPMC:

1. Ukucaphuka okuphantsi, ukushisa okuphezulu kunye ne-non-toxic;

2. Ukuzinza kwexabiso le-pH ebanzi, enokuqinisekisa ukuzinza kwayo kuluhlu lwexabiso le-pH 6-10;

3. Ukuphucula imeko;

4. Ukwandisa i-foam, ukuzinzisa i-foam, ukuphucula ukuvakalelwa kwesikhumba;

5. Ukuphucula ngokufanelekileyo ukuhamba kwamanzi kwisistim.

Umda wokusetyenziswa kwe-HPMC yomgangatho wekhemikhali yomgangatho weseli:

Isetyenziswa kwishampu, ukuhlamba umzimba, isepha yesitya, isicoci sempahla, ijeli, isilungisi seenwele, iimveliso zesitayile, intlama yamazinyo, amathe, amanzi okudlala.

Indima yebakala lemichiza yemihla ngemihlaiselulosi HPMC:

Eyona nto isetyenziselwa ukutyeba, ugwebu, i-emulsification ezinzileyo, i-dispersion, adhesion, ukuphuculwa kokwenza ifilim kunye neendawo zokugcina amanzi, iimveliso ze-viscosity ephezulu zisetyenziselwa ukutyeba, iimveliso eziphantsi kwe-viscosity zisetyenziselwa ikakhulu ukusasazwa kunye nokwenza ifilimu.

Itekhnoloji ye-HPMC yomgangatho wemichiza yemihla ngemihla:

Isixa se-hydroxypropyl methylcellulose esilungele ishishini lemichiza yemihla ngemihla ngokubanzi
