Kodi HPMC imasungunuka m'madzi otentha?

Hydroxypropyl methylcellulose (hpmc)ndi polima wosiyanasiyana womwe umapeza ntchito kwambiri m'mafakitale monga mankhwala opangira mankhwala, zodzoladzola, zomanga, ndi chakudya. Chimodzi mwazinthu zomwe zimadziwika ndi kusungunuka kwake m'madzi, makamaka m'madzi otentha.

1. Kodi hpmc ndi chiyani?

HPMC ndi chopanga chopangidwa, chambiri, ma viscoelastic polity ochokera ku cellulose. Imapezeka pochiritsa cellulose ndi alkali ndi ma propylene oxide, kenako methylation. Njirayi imabweretsa polymer yosungunuka yamadzi yomwe ili ndi zowongolera za cellulose zachilengedwe.

2. Solubility wa HPMC m'madzi

HPMC imawonetsa bwino kusungunuka m'madzi, makamaka ngati madzi amatenthedwa. Kusungunuka kumeneku kumachitika chifukwa cha magulu a hydrophilic molekyu ya HPMC, ndiye kuti ma hydroxyl (-oh) magulu a ether. Maguluwa amalumikizana ndi mamolekyulu amadzi kudzera pa holdrogen yolumikizira, kufalitsa kusungunuka kwa HPMC m'matumba am'madzi.

3. Zotsatira za kutentha pa kusungunuka

Kusungunuka kwaHpmcKuchuluka ndi kutentha. Pa kutentha kwambiri, mamolekyu amadzi ali ndi mphamvu zazikulu za kinetic, zomwe zimapangitsa kuti zikhale zosunthika moleclar komanso kulowa bwino kwa madzi kulowa mu polymer matrix. Izi zimapangitsa kusungunuka kwakanthawi katswiri ndi kusungunuka kwakukulu kwa HPMC m'madzi otentha poyerekeza ndi madzi ozizira.

4. Kugwiritsa ntchito mankhwala opanga mankhwala

M'mapangidwe opanga mankhwala, HPMC imagwiritsidwa ntchito ngati wothandizira, okhazikika, ndi filimu yomwe kale mu mitundu yolimba ya mikanda monga mapiritsi ndi makapisozi. Kusungunuka kwake m'madzi otentha kumapangitsa kuti ikhale yoyenera kukonzekera mayankho am'madzi kapena kuyimilira kwa mankhwala osokoneza bongo. Mwachitsanzo, hpmc imatha kusungunuka m'madzi otentha kuti apange gels gels gel, yomwe itha kugwiritsidwa ntchito ngati khola kuti mutengere tinthu tambiri popanga piritsi.

5. Gwiritsani ntchito zomangamanga

M'makampani omanga, HPMC imagwiritsidwa ntchito muzopangidwa ndi sile monga matayala, mavle, ndi kumapereka. Kusungunuka kwamadzi kumalola kubalalitsidwa kosavuta ndi kugawa yunifolomu mkati mwa simentant matrix. Popanga filimu yoteteza pazinthu za simenti, hpmc zimathandiza, kusungidwa kwamadzi, komanso kutsatira zida zomangazi.

6. Kufunika kwa makampani ogulitsa zakudya

HPMC imatenganso gawo lofunikira mu malonda azakudya, pomwe amalemba ntchito ngati thiccener, emulsifier, ndi okhazikika m'magulu osiyanasiyana. Kusungunuka kwake m'madzi otentha kumathandiza kukonza zomveka bwino, zothetsera ma viscous zomwe zimathandizira kuti pakhale kapangidwe ka chakudya. Mwachitsanzo, hpmc imatha kusungunuka m'madzi otentha kuti apange gels, yomwe imawonjezedwa ku Susuces, sopo, kapena zakudya kuti zikhale pakamwa pawo komanso kukhazikika.

7. Kumaliza

Hpmcamasungunuka m'madzi otentha, chifukwa cha chilengedwe chake cha hydrophilic ndi mawonekedwe apadera. Katunduyu amapanga chinthu chofunikira pakugwiritsa ntchito mafakitale osiyanasiyana m'mitundu yosiyanasiyana, kuphatikizapo zamankhwala osiyanasiyana, zomanga, ndi chakudya. Kumvetsetsa machitidwe a HPMC ndikofunikira kwa opanga ndi opanga kuti athe kukonza zomwe zimagwiritsidwa ntchito muzinthu zosiyanasiyana.
