Hydroxypypyl methylcellulose (hpmc) ndi ethel ether ether yomwe ili ndi maimelo osiyanasiyana, kuwonetsedwa ndi zilembo ndi manambala. Maphunzirowa amaimira mitundu yosiyanasiyana, kuphatikiza mitundu yolemera kwa maselo, hydroxypropyl, ndi mafayilo. Nayi kuwonongeka kwa ma gradies a HPMC yomwe mudatchulawa:

1. Hpmc e3:
   • Kalasi iyi mwina ikunena za HPMC yokhala ndi ma visct 2.4-3.6cps. Nambala 3 ikuwonetsa mawonekedwe a 2% ya madzi am'madzi a 2%, ndipo manambala apamwamba amawonetsa mafayilo apamwamba.
2. HPMC E5:
   • Zofanana ndi e3, HPMC E5 imayimira kalasi yosiyanasiyana ya ma vidiyo. Nambala 5 ikuwonetsa mawonekedwe a ma viscton 4.0-6.0 cps ya 2% yothetsera njira.
3. HPMC E6:
   • HPMC E6 ndi kalasi ina yokhala ndi mbiri yosiyanasiyana ya ma visc. Nambala 6 ikuyimira ma visct.8-7.2 CPS ya 2% yankho.
4. HPMC E15:
   • HPMC E15 Yathani kuyimira kalasi yapamwamba kwambiri poyerekeza ndi E3, E5, kapena E6. Nambala 15 ikuwonetsa ma visclence 12.0-18.0cps ya 2% yothetsera njira yosinthira, ndikuwonetsa kusinthasintha.
5. Hpmc e50:
   • HPMC E50 imawonetsa kalasi yapamwamba kwambiri, yomwe ndi nambala 50 yoimira ma visclence 40.0-60.0 cps yankho la 2%. Kalasi iyi ikhoza kukhala ndi ma visn apamwamba kwambiri poyerekeza ndi E3, E5, E6, kapena E15.
6. Hpmc e4m:
   • "M" ku E4m nthawi zambiri imatanthawuza kwapakatikati pa ma visten 3200-4800cps. HPMC E4m imayimira kalasi yokhala ndi mawonekedwe owoneka bwino. Zitha kukhala zoyenera kugwiritsa ntchito moyenera pakati pa madzi ndi makulidwe.

Mukamasankha kalasi ya HPMC kuti mupeze pulogalamu inayake, m'maganizo kuphatikiza mafayilo omwe mukufuna, kusungunuka komanso zinthu zina. HPMC imagwiritsidwa ntchito kwambiri m'makampani monga zomangamanga, mankhwala opangira mankhwala, zodzoladzola, ndi chakudya.

Mu chakudya, hpmc nthawi zambiri amagwiritsidwa ntchito ngati chowonjezera muzinthu zosagwirizana ndi mpweya wowonjezera ngati kusungidwa kwamadzi, kutopa, ndi kotsatira. Mu mankhwala opangira mankhwala ndi zodzoladzola, hpmc imagwiritsidwa ntchito popanga filimu ndi makulidwe.

Ndikofunikira kukambirana ndi wopanga kapena wopereka kuti adziwe zambiri zaukadaulo, kuphatikizapo zomwe amagwiritsa ntchito ndikugwiritsa ntchito pulogalamu iliyonse ya HPMC. Opanga nthawi zambiri amapereka ma sheet a data ndi zolemba zogulitsa kuti aziwongolera ogwiritsa ntchito posankha gawo labwino kwambiri pazosowa zawo.
