Hydroxypropyl methylcellulose (HPMC)ndi non-ionic cellulose ether kwambiri ntchito zomangira, mankhwala, chakudya, zodzoladzola ndi mafakitale ena. Waukulu luso zizindikiro za HPMC monga katundu thupi ndi mankhwala, solubility, mamasukidwe akayendedwe, digiri ya m'malo, etc.
1. Maonekedwe ndi makhalidwe ofunika
HPMC nthawi zambiri imakhala yoyera kapena yoyera ufa, yopanda fungo, yopanda pake, yopanda poizoni, yokhala ndi madzi osungunuka komanso okhazikika. Imatha kumwazikana mwachangu ndikusungunula m'madzi ozizira kuti ipangike powonekera kapena pang'ono turbid colloidal solution, ndipo imakhala ndi kusungunuka kosakwanira mu zosungunulira za organic.
2. Viscosity
Viscosity ndi chimodzi mwazinthu zofunikira kwambiri zaukadaulo za HPMC, zomwe zimatsimikizira magwiridwe antchito a AnxinCel®HPMC pamapulogalamu osiyanasiyana. Kukhuthala kwa HPMC kumayesedwa ngati njira yamadzimadzi 2% pa 20 ° C, ndipo mawonekedwe a viscosity wamba amachokera ku 5 mPa · s mpaka 200,000 mPa · s. The apamwamba mamasukidwe akayendedwe, mphamvu thickening zotsatira za yankho ndi bwino rheology. Akagwiritsidwa ntchito m'mafakitale monga zomangamanga ndi mankhwala, kalasi yoyenera ya viscosity iyenera kusankhidwa malinga ndi zosowa zenizeni.
3. Methoxy ndi Hydroxypropoxy Content
Mankhwala a HPMC amatsimikiziridwa makamaka ndi methoxy (-OCH₃) ndi hydroxypropoxy (-OCH₂CHOHCH₃) madigiri olowa m'malo. HPMC yokhala ndi madigiri osiyanasiyana olowa m'malo amawonetsa kusungunuka kosiyanasiyana, zochitika zapamtunda ndi kutentha kwa gelation.
Methoxy Content: Nthawi zambiri pakati pa 19.0% ndi 30.0%.
Hydroxypropoxy Content: Nthawi zambiri pakati pa 4.0% ndi 12.0%.
4. Chinyezi
Chinyezi cha HPMC nthawi zambiri chimayendetsedwa pa ≤5.0%. Kuchuluka kwa chinyezi kudzakhudza kukhazikika ndi kugwiritsa ntchito zotsatira za mankhwala.
5. Phulusa
Phulusa ndilotsalira pambuyo pa kutenthedwa kwa HPMC, makamaka kuchokera ku mchere wa inorganic womwe umagwiritsidwa ntchito popanga. Zomwe zili phulusa nthawi zambiri zimayendetsedwa pa ≤1.0%. Phulusa lalitali kwambiri lingakhudze kuwonekera komanso kuyera kwa HPMC.
6. Kusungunuka ndi kuwonekera
HPMC ili ndi kusungunuka kwamadzi bwino ndipo imatha kusungunuka m'madzi ozizira kuti ipange njira yofanana ya colloidal. Kuwonekera kwa yankho kumadalira chiyero cha HPMC ndi njira yake yowonongeka. Njira yabwino kwambiri ya HPMC nthawi zambiri imakhala yowonekera kapena yamkaka pang'ono.
7. Kutentha kwa Gel
HPMC amadzimadzi njira kupanga gel osakaniza pa kutentha zina. Kutentha kwake kwa gel nthawi zambiri kumakhala pakati pa 50 ndi 90 ° C, kutengera zomwe zili mu methoxy ndi hydroxypropoxy. HPMC yokhala ndi otsika methoxy zili ndi kutentha gel osakaniza, pamene HPMC ndi mkulu hydroxypropoxy zili ndi kutentha gel osakaniza.
8. pH mtengo
Phindu la pH la AnxinCel®HPMC lamadzimadzi lamadzimadzi nthawi zambiri limakhala pakati pa 5.0 ndi 8.0, lomwe silinalowererepo kapena lopanda mphamvu za alkaline komanso loyenera kumadera osiyanasiyana ogwiritsira ntchito.
9. Tinthu Kukula
Ubwino wa HPMC nthawi zambiri umawonetsedwa ngati kuchuluka komwe kumadutsa pazenera la 80-mesh kapena 100-mesh. Nthawi zambiri pamafunika kuti ≥98% idutse pazenera la 80-mesh kuti iwonetsetse kuti ili ndi dispersibility yabwino komanso kusungunuka ikagwiritsidwa ntchito.
10. Zolemera zachitsulo
Zomwe zili muzitsulo zolemera (monga lead ndi arsenic) za HPMC ziyenera kutsata miyezo yoyenera yamakampani. Nthawi zambiri, zomwe zimatsogolera ndi ≤10 ppm ndipo za arsenic ndi ≤3 ppm. Makamaka pazakudya ndi kalasi yamankhwala HPMC, zofunika pazachuma cha heavy metal ndizovuta kwambiri.
11. Zizindikiro za tizilombo
Pa mankhwala ndi chakudya giredi ya AnxinCel®HPMC, kuipitsidwa kwa tizilombo toyambitsa matenda kuyenera kuwongoleredwa, kuphatikiza kuchuluka kwa koloni, nkhungu, yisiti, E. coli, ndi zina zambiri, zomwe nthawi zambiri zimafunikira:
Chiwerengero chonse cha magulu ≤1000 CFU/g
Chiwerengero chonse cha nkhungu ndi yisiti ≤100 CFU/g
E. coli, Salmonella, ndi zina zotero siziyenera kuzindikirika
12. Magawo akuluakulu ogwiritsira ntchito
HPMC chimagwiritsidwa ntchito m'mafakitale ambiri chifukwa thickening, madzi posungira, filimu kupanga, mafuta, emulsification ndi katundu:
Makampani omanga: Monga chokhuthala komanso chosungira madzi mumatope a simenti, ufa wa putty, zomatira matailosi, ndi zokutira zopanda madzi kuti ntchito yomanga ikhale yabwino.
Makampani opanga mankhwala: Amagwiritsidwa ntchito ngati zomatira, zotulutsa zokhazikika, ndi zipolopolo za kapisozi zopangira mapiritsi amankhwala.
Makampani azakudya: amagwiritsidwa ntchito ngati emulsifier, stabilizer, thickener, amagwiritsidwa ntchito mu odzola, zakumwa, zophika, etc.
Makampani opanga mankhwala atsiku ndi tsiku: amagwiritsidwa ntchito ngati thickener ndi emulsifier stabilizer muzinthu zosamalira khungu, zotsukira, ndi ma shampoos.
The luso zizindikiro zaMtengo wa HPMCzikuphatikizapo mamasukidwe akayendedwe, digiri ya m'malo (okhutira hydrolyzed gulu), chinyezi, phulusa, pH mtengo, gel osakaniza kutentha, fineness, heavy metal okhutira, etc. Zizindikiro izi zimatsimikizira ntchito yake ntchito m'madera osiyanasiyana. Posankha HPMC, ogwiritsa ntchito ayenera kudziwa zoyenera malinga ndi zofunikira za pulogalamuyo kuti atsimikizire kugwiritsa ntchito bwino.
