Hydroxypropyl Methyl Cellulose Molecular Weight Viscosity

Hydroxypropylmethylcellulose (HPMC) ndi polima ntchito kwambiri m'mafakitale osiyanasiyana. Ndiwopanda ionic cellulose ether, wosungunuka m'madzi, wopanda poizoni komanso wosakwiyitsa. HPMC imagwiritsidwa ntchito ngati thickener, binder ndi emulsifier muzakudya zambiri, mankhwala ndi chisamaliro chamunthu.

Chimodzi mwa zinthu zofunika kwambiri za HPMC ndi kulemera kwake kwa maselo, zomwe zimakhudza kukhuthala kwake. Viscosity ndi muyeso wa kukana kwamadzimadzi kuyenda. Kukwera mamasukidwe akayendedwe, ndi kukhuthala kwamadzimadzi. Kulemera kwa maselo ndi muyeso wa kukula kwa maselo, omwe amagwirizana mwachindunji ndi kukhuthala kwa HPMC.

HPMC imapezeka m'makalasi osiyanasiyana malinga ndi kulemera kwake kwa maselo. Kukhuthala kwa HPMC kumawonjezera kulemera kwa maselo. Kukhuthala kwa HPMC kumakhudzidwanso ndi kuchuluka kwa m'malo (DS), komwe ndi kuchuluka kwa magulu a hydroxypropyl ndi methyl omwe amamangiriridwa pamsana wa cellulose. Kukwera kwa DS, ndikokwera kwambiri kulemera kwa maselo ndi kukhuthala kwa HPMC.

Kukhuthala kwa HPMC kumakhudzidwanso ndi ndende ya polima mu yankho. Pazigawo zotsika, maunyolo a polima amamwazikana ndipo kukhuthala kwake kumakhala kochepa. Pamene ndende ikuchulukirachulukira, maunyolo a polima amayamba kuphatikizika ndikumangirira, zomwe zimapangitsa kuwonjezeka kwa mamasukidwe akayendedwe. Kuphatikizika komwe maunyolo a polima amayamba kuphatikizika kumatchedwa kuphatikizika.

The molecular kulemera ndi mamasukidwe akayendedwe a HPMC ndi zofunika magawo ambiri mankhwala formulations. M'makampani azakudya, HPMC imagwiritsidwa ntchito ngati chowonjezera cha sosi, mavalidwe ndi zinthu zophika. Kulemera koyenera kwa maselo ndi kukhuthala kwa HPMC kumatsimikizira mawonekedwe omwe amafunidwa komanso kumva kwapakamwa kwa chinthu chomaliza.

M'makampani opanga mankhwala, HPMC imagwiritsidwa ntchito ngati chomangira mapiritsi ndi makapisozi. Kulemera kwa maselo ndi kukhuthala kwa HPMC kumatsimikizira mphamvu ya piritsi komanso kuthekera kwake kusungunuka m'matumbo am'mimba.

M'makampani osamalira anthu, HPMC imagwiritsidwa ntchito ngati chowonjezera komanso emulsifier mu ma shampoos, mafuta odzola ndi mafuta opaka. The oyenera maselo kulemera ndi mamasukidwe akayendedwe a HPMC kuonetsetsa kusasinthasintha abwino ndi kukhazikika kwa mankhwala.

Mwachidule, kulemera kwa maselo ndi kukhuthala kwa HPMC ndizofunikira zomwe zimakhudza magwiridwe ake m'mafakitale osiyanasiyana. Kumvetsetsa mgwirizano wapakati pa magawowa ndikofunikira kwambiri popanga zinthu zomwe zimakwaniritsa zomwe mukufuna. HPMC ndi polima wosunthika komanso wamtengo wapatali womwe umathandizira kuwongolera komanso magwiridwe antchito azinthu zambiri.
