Kusanthula ndi kuyesa kwa hydroxypropyl meth cellose (hpmc)

Hydroxypropyl me cellulose (hpmc) ndi polymer yosiyanasiyana yomwe imagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana, kuphatikizapo zamankhwala osiyanasiyana, kuphatikiza, chakudya, zodzola. Pepala ili limapereka kusanthula kokwanira ndi kuyesa kwa HPMC, kuphimba kapangidwe kake, katundu, kupanga njira, njira, ndi njira zoyesera.

1. Nthangole:
Hydroxypropyl Medielose (HPMC) ndi cellulose yopezeka pochiritsa cellulose ndi mehyln chloride. Amagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana chifukwa cha zinthu zake zapadera, kuphatikizapo kukula, kapangidwe ka mafilimu, kusungidwa kwamadzi, komanso kumanga.

2. kapangidwe kake ndi katundu wa HPMC:
HPMC ndi ma cellulose ether ether ndi njira ya mankhwala (c6h7o2 (o) 3-x (och3) x) n, komwe x imayimira kuchuluka kwa zolowa m'malo. Mlingo wazolowa m'malo mwake umakhudza katundu wa HPMC, kuphatikiza mamasukidwe, kusasinthika, komanso kukhazikika kwa mafuta. HPMC imasungunuka m'madzi ndi ena okhazikika, ndikupanga mayankho omveka bwino komanso a viscous.

3.Kodi njira za HPMC:
Njira zopangira za HPMC zimaphatikizapo kusinthika kwa cellulose pogwiritsa ntchito ma propylen oxide ndi methyl chloride. Mlingo wazolowa mukhoza kuwongolera mwa kusintha zochitika, monga kutentha, ph, ndi nthawi. Zotsatira za HPMC zimayeretsedwa ndikutsuka njira kuti mupeze zomwe mukufuna.

4.PapPectictions ya HPMC:
HPMC imapeza ntchito zochulukirapo m'mafakitale osiyanasiyana, kuphatikizapo zamankhwala, chakudya, zomangamanga, zodzola komanso zinthu zosamalira pandekha. Mu mankhwala opangira mankhwala, hpmc imagwiritsidwa ntchito ngati thicker, binder, ndi kusungulumwa-kusungulumwa-kusungulumwa mapangidwe a piritsi. Pakugulitsa zakudya, zimagwiritsidwa ntchito ngati kukula komanso kukhazikika kwamisuzi m'misefu, mavalidwe, ndi mkaka. Pomanga, hpmc imawonjezeredwa ndi maboti, ma plaksters, ndi tiles kuti musangalale komanso kutsatira. Kuphatikiza apo, HPMC imagwiritsidwa ntchito popanga mafilimu ake komanso yonyowa.

Zosangalatsa za HPMC:
a. Kusanthula Kosanthula: Kusintha kwa zitsulo zopezeka (FTIR) Magkitala A Spectropy ndi nyukiliya (NMR) STRONOSOPY

b. Kusanthula kwa Rheogical: Kuyesa kwa Rheological kumawunikira mafayilo a HPMC, kulimba mtima, ndi kufesa katundu, komwe ndikofunikira kugwiritsa ntchito pamapangidwe osiyanasiyana.

c. Kusanthula kwamafuta: Kusakanizira kalori calorimetry (TGA) Kusanthula kwa thermavimet (TGA) kumalemba ntchito kukhazikika kwa HPMC ndi kutentha kwake, ndikuwonetsetsa kuti mwayenera kugwiritsa ntchito mapulogalamu apadera.

d. Kusanthula Chinyontho: Tizilombo tating'onoting'ono tigwiritsidwe ntchito kuti tidziwe chinyezi cha HPMC, chomwe ndichofunikira kuti chikhalebe bata ndi moyo wa alumali.

e. Kusanthula kwa tinthu: Njira zophatikizira ndi njira zama microscopy zimagwiritsidwa ntchito kuyeza kuchuluka kwa tinthu tating'onoting'ono tofara kwa ma hpmc, kuonetsetsa kusasinthika.

6. Kuwongolera kwa HPMC:
Njira Zowongolera Zowongolera za HPMC zimaphatikizapo kuyezetsa zolimba za zinthu zopangira, zitsanzo za ndondomeko, ndi zinthu zomaliza kuti zitsimikizire kutsatira malamulo ndi mfundo zowongolera. Izi zimaphatikizapo kuyesa kwa batch to-batch.

Hydroxypropyl methy cellulose (hpmc) ndi polymer yosiyanasiyana ndi ntchito zosiyanasiyana pamakampani osiyanasiyana. Pakusanthula kwathunthu ndi kuyesa, katundu wofunikira ndi mawonekedwe a HPMC angatsimikizidwe, onetsetsani kuti malinga ndi ntchito zapaderazo zomwe mungagwiritse ntchito komanso kukhala ndi miyezo yopanga nthawi zonse.
