▲Hydroxypropyl methyl cellulose (HPMC)ndi ufa woyera wopanda fungo, wosakoma, wopanda poizoni. Pambuyo pakusungunuka kwathunthu m'madzi, hydroxypropyl methyl cellulose ipanga mawonekedwe a viscous colloid.
▲ The zopangira zazikulu za hydroxypropyl methyl cellulose (HPMC): woyengedwa thonje, methyl kolorayidi, propylene okusayidi, ndi zipangizo zina, caustic koloko, asidi, toluene, isopropanol, etc.
Kuyerekeza zabwino ndi kuipa kwa hydroxypropyl methyl cellulose:
1.Pure hydroxypropyl methyl cellulose HPMC ndi yotayirira yowoneka ndipo imakhala ndi kachulukidwe kakang'ono, ndi sikelo ya 0.3-0.4 / ml.
HPMC yopangidwa ndi chipwirikiti imakhala ndi madzi abwino kwambiri ndipo imakhala yolemera kwambiri, yomwe imakhala yosiyana kwambiri ndi maonekedwe enieni.
2.Pure hydroxypropyl methyl cellulose HPMC yamadzimadzi yamadzimadzi imamveka bwino, kutumizirana kwakukulu, kusungirako madzi> 97%.
Njira yowonongeka ya HPMC yamadzimadzi imakhala yonyansa, ndipo kuchuluka kwa madzi osungirako kumakhala kovuta kufika 80%.
3.Pure HPMC sayenera fungo la ammonia, wowuma ndi mowa.
HPMC yosokoneza nthawi zambiri imatha kununkhiza zokometsera zamitundu yonse, ngakhale itakhala yopanda pake, imamva kulemera.
4.Pure hydroxypropyl methyl cellulose HPMC ufa ndi fibrous pansi pa microscope kapena galasi lokulitsa.
HPMC yosokoneza imatha kuwonedwa ngati zolimba zolimba kapena makhiristo pansi pa maikulosikopu kapena galasi lokulitsa.
Ndi mbali ziti zodziwira zabwino ndi zoyipa za hydroxypropyl methyl cellulose?
1. digiri yoyera
Ngakhale kuyera sikungadziwe ngati HPMC ndi yosavuta kugwiritsa ntchito, ndipo ngati zopangira zoyera zikuwonjezeredwa panthawi yopanga, zimakhudza mtundu wake. Komabe, zinthu zambiri zabwino zimakhala ndi zoyera zabwino.
2.Ubwino
Ubwino wa HPMC nthawi zambiri umakhala ndi mauna 80 ndi mauna 100, ndipo kuwongolera bwino, kunena zambiri, kumakhala bwinoko.
3.Kutumiza
Ikanihydroxypropyl methyl cellulose (HPMC)m'madzi kuti apange colloid yowonekera, ndikuyang'ana kuwala kwake. Kukwera kwamagetsi otumiza kuwala, kumakhala bwino, kusonyeza kuti muli zinthu zochepa zosasungunuka mmenemo. The permeability wa ofukula reactors zambiri zabwino, pamene yopingasa riyakitala ndi zoipa.
4.Chigawo
Kuchuluka kwa mphamvu yokoka yeniyeni, kulemera kwake kumakhala bwinoko. Kutsimikizika ndi kwakukulu, makamaka chifukwa zomwe zili mugulu la hydroxypropyl momwemo ndizazikulu, ndipo zomwe zili mugulu la hydroxypropyl ndizokwera, kusungirako madzi kuli bwino.
