I-rheology kunye nokuhambelana kwe-hydroxypropyl methylcellulose (HPMC) kunye ne-hydroxypropyl starch (HPS) idlala indima ebalulekileyo kumashishini ahlukeneyo, kubandakanywa amayeza, ukutya, izithambiso kunye nokwakha.Ukuqonda unxibelelwano phakathi kwezi polima zimbini kubalulekile ekuphuculeni ukusebenza kwazo kunye nokuphuhlisa iimveliso ezintsha.Eli phepha lijolise ukuhlola iimpawu ze-rheological kunye nokuhambelana kwe-HPMC / HPS.
Iinkcazelo ngeRheological:
I-Rheology sisifundo sendlela izinto eziguquka ngayo kwaye zihamba phantsi kweempembelelo zamandla angaphandle.Kwimeko ye-HPMC / HPS eyinkimbinkimbi, iipropati ze-rheological zimisela i-viscosity, ukuziphatha kwe-gelation, kunye neempawu zokuhamba ngokubanzi zomxube we-polymer.Ukuziphatha kwe-rheological ye-complex inokuchatshazelwa zizinto ezinje ngoxinaniso lwepolymer, ubunzima bemolekyuli, ubushushu, kunye nesantya sokucheba.
Ukuhambelana kwe-HPMC kunye ne-HPS:
Ukuhambelana phakathi kwe-HPMC kunye ne-HPS kubalulekile ukuqinisekisa ukwakheka kwezakhiwo ezizinzileyo ezineempawu ezinqwenelekayo.Ukuhambelana kubhekiselele kwisakhono seepolima ezimbini okanye ngaphezulu ukuxuba kunye nokwenza inkqubo elinganayo ngaphandle kokwahlulwa kwesigaba okanye ukulahleka kokusebenza.
Izinto ezichaphazela irheology kunye nokuhambelana:
I-Polymer ratio: Umlinganiselo we-HPMC ukuya kwi-HPS kwi-complex inokuchaphazela kakhulu iimpawu zayo ze-rheological kunye nokuhambelana.
Ubunzima be-molecular: Ubunzima be-molecular of HPMC kunye ne-HPS buchaphazela i-rheology kunye nokuhambelana kwe-complex .
Ubushushu: Iqondo lokushisa apho i-complex ilungiswa kwaye ivavanywa ichaphazela ukuziphatha kwayo kwe-rheological.
Ixabiso le-Shear: Izinga lokucheba elisetyenziswe ngexesha lokuvavanya okanye ukucutshungulwa kunokuchaphazela iimpawu ze-rheological ze-HPMC / HPS complex.Amazinga aphezulu okucheba angakhokelela ekuziphatheni kokucheba, apho i-viscosity iyancipha ngokunyuka kwesantya sokucheba.
Usetyenziso:
I-rheology kunye nokuhambelana kwe-HPMC / HPS eyinkimbinkimbi ineempembelelo ezibalulekileyo kumashishini ahlukeneyo. njenge-ejenti yokuqina, isizinzi, okanye i-emulsifier.Kwizinto zokwakha, ii-complexes zinokuphucula ukusebenza kunye nokubambelela kwiinkqubo ze-cemented.
I-Rheology kunye nokuhambelana kwe-HPMC / HPS complexes yingqwalasela ebalulekileyo ekuphuculeni ukusebenza kwazo kwizicelo ezahlukeneyo. kunye nophuhliso kule ndawo kunokukhokelela ekudalweni kweemveliso ezintsha ezinomsebenzi ophuculweyo kunye nokusebenza okuphuculweyo kumashishini amaninzi.
