Oku kubaluleke kakhulu kwizicelo ezifana nodaka lwe-plaster kunye ne-adhesives ye-tile, enokuphucula kakhulu umgangatho wokwakha kunye nokuqina.

 

5. Lungisa ixesha lokumisela ikhonkrithi

I-HPMC inomsebenzi othile wokulawula ixesha lokuhlangana. Ngokweemfuno, ngokulungelelanisa inani le-HPMC elongeziweyo, ixesha lokumisela ikhonkrithi linokwandiswa okanye lifinyezwe, eliququzelela ukulungiswa kokwakhiwa kunye nokulawulwa kwenkqubela phambili. Oku kubaluleke ngakumbi xa ukwakhiwa kufuna ixesha elide okanye phantsi kweemeko eziphezulu zokushisa. Inokuthintela ikhonkrithi ekuqiniseni ngokukhawuleza kwaye iqinisekise umgangatho wokwakha.

 

6. Ukuphucula ukuxhathisa ukunyibilika komkhenkce kwekhonkrithi

Ukugcinwa kwamanzi kunye nesiphumo sokuqina kwe-HPMC kunokuphucula isakhiwo sangaphakathi sekhonkrithi kwaye siyenze ibe yinkimbinkimbi, ngaloo ndlela iphucula ukuxhathisa ukunyibilika kwekhonkrithi. Kwiindawo ezibandayo okanye iiprojekthi ezifuna ukuxhathisa imijikelo yokunyibilika komkhenkce, ukongeza i-HPMC inokuthintela ngokufanelekileyo ukuqhekeka kunye nokuqhekeka kwekhonkrithi okubangelwa yimijikelo yokukhenkcisa kunye nokwandisa ubomi bayo benkonzo.

 

Ukusetyenziswa kwe-HPMC kwikhonkrithi

I-HPMC isetyenziswa ngokubanzi kwikhonkrithi, ngakumbi kule miba ilandelayo:
