Kodi pali kusiyana kotani pakati pa HPMC E5 ndi E15?

Hydroxypropyl methylcellulose (hpmc) ndi zopanga, chonde, ma police a ma viscoecial omwe amapeza kugwiritsa ntchito kwambiri m'mafakitale osiyanasiyana kuphatikiza mankhwala, zomangamanga, chakudya, ndi zodzola. Amachokera ku celluluse kudzera mu kusintha kwa mankhwala. HPMC imapezeka m'magulu osiyanasiyana omwe amadziwika ndi digiri ya zolowa m'malo mwa hydroxypyl ndi methoxy magulu, komanso mawonekedwe a yankho. Maphunziro amadziwika ndi kuphatikiza kwa zilembo ndi manambala, monga E5 ndi E15.

1. Kupanga kwa molecular:
HPMC E5:
HPMC E5 ikutanthauza kalasi ya HPMC yokhala ndi digiri yotsika ya hydroxypyl ndi methoxy magulu poyerekeza ndi E15.
Kutsika kwa cholowa m'malo mwake kumaonetsa ma hydroxypyl ochepa ndi methoxy magulu pa cellulose mu cellulose mu unyolo.
HPMC E15:
Komabe, hpmc e15, kumbali inayo, ili ndi kuchuluka kwa hydroxypyl ndi methoxy magulu poyerekeza ndi E5.
Izi zikutanthauza kuchuluka kwakukulu kwa hydroxypyl ndi methoxy magulu amodzi pa cellulose mu unyolo wamkati.

2. Makutu:
HPMC E5:
HPMC E5 nthawi zambiri imakhala ndi ma vidiyo otsika poyerekeza ndi E15.
Kutsitsa ma visncy ngati E5 nthawi zambiri amagwiritsidwa ntchito ngati zotsatira zam'mimba zomwe zimafunidwa.
HPMC E15:
HPMC E15 ili ndi ufa wapamwamba poyerekeza ndi E5.
Makulidwe apamwamba a Mavisi ngati E15 amasankhidwa pomwe ma thicker osinthika kapena malo abwino osasungidwa amafunikira pakugwiritsa ntchito.

3. Madzi Kusungunuka:
HPMC E5:
Onse a HPMC E5 ndi E15 ndi osungunuka madzi.
Komabe, solumile imatha kukhala yosiyanasiyana motengera zigawo zina zopanga ndi zachilengedwe.
HPMC E15:
Monga E5, HPMC E15 ikusungunuka mosavuta m'madzi.
Zimapanga zomveka bwino, zothetsera nsabwe pazachilengedwe.

4. Mapulogalamu:
HPMC E5:
HPMC E5 imagwiritsidwa ntchito nthawi zambiri pamapulogalamu omwe akuwoneka bwino komanso kusinthasintha kwamphamvu.
Zitsanzo za mapulogalamu zikuphatikiza:
Mapangidwe opanga mankhwala (monga omanga, osagwirizana, kapena omasulidwa - omasulidwa).
Zinthu zachisamaliro zaumwini (monga mabatani odzola, mafuta, ndi shampoos).
Makampani opanga zakudya (ngati wothandizira kapena wolumikizira).
Makampani omanga (monga kuwonjezera pazinthu zopangidwa ndi simenti kuti zitheke komanso kusungidwa kwamadzi).
HPMC E15:
HPMC E15 imakonda kugwiritsa ntchito mapulogalamu ofunikira mafayilo apamwamba komanso mphamvu yamphamvu.
Ntchito za HPMC E15 Phatikizani:
Ma proctocemations a mankhwala (monga othandizira, kapena osuta fodya).
Zipangizo zomanga (monga Thicner kapena Blander mu Asile Astherates, pulasitala, kapena grout).
Makampani ogulitsa zakudya (monga kukula kwamphamvu m'misuzi, ma puddings, kapena mkaka).
Makampani opanga zodzikongoletsera (mu zinthu zomwe zimafunikira mafayilo apamwamba, monga ma gels a tsitsi kapena magwiridwe antchito).

5. Kupanga:
HPMC E5 ndi E15:
Njira zopangira zonse za HPMC E5 ndi E15 zimaphatikizapo kusintha kwa cellulose ndi ma propylene oxide ndi methyl chloride.
Mlingo wazolowa m'malo mwake umayendetsedwa panthawi ya synthesis kuti mukwaniritse zomwe mukufuna.
Magawo osiyanasiyana monga momwe amachitira nthawi, kutentha, komanso kuchuluka kwa alangizi amakonzedwa kuti apange hpmc yokhala ndi mawonekedwe.

Kusiyana kwakukulu pakati pa HPMC E5 ndi E15 kunama pazinthu zawo, mafakisoni, ndi ntchito. Pomwe masukulu onse ndi osungunuka osungunuka madzi kuchokera ku cellulose, hpmc e5 ali ndi malire otsika kwambiri komanso ma vidiyo poyerekeza ndi HPMC E15. Zotsatira zake, E5 ndi yoyenera kugwiritsa ntchito mafayilo otsika komanso katundu wokhazikika, pomwe E15 amasankhidwa kuti agwiritse ntchito akufunika ma victoni apamwamba komanso kukula kwamphamvu. Kumvetsetsa izi ndikofunikira posankha gawo loyenera la hpmc la mapangidwe apadera ndi ntchito.
