HPMC (hydroxypropyl methylcellulose) ndi matope osakaniza ofunikira omwe amagwiritsidwa ntchito kwambiri pomanga. Ntchito zake zazikulu ndikuwongolera kusungidwa kwamadzi mumatope, kukonza magwiridwe antchito komanso kukulitsa kukana kwa ming'alu. Ubwino wa AnxinCel®HPMC ndi chimodzi mwazinthu zofunika kwambiri pakuchita kwake, zomwe zimakhudza mwachindunji kusungunuka kwake ndi kugawa mumatope komanso kusintha kwake pazinthu zamatope.
1. Tanthauzo la ubwino wa HPMC
HPMC fineness nthawi zambiri anasonyeza mwa mawu a pafupifupi tinthu kukula kwake particles kapena kuchuluka kudutsa sieve yeniyeni. HPMC particles ndi fineness mkulu ndi ang'onoang'ono ndi lalikulu enieni pamwamba m'dera; HPMC particles ndi fineness otsika ndi zazikulu ndi ang'onoang'ono enieni pamwamba m'dera. Fineness imakhudza kwambiri kuchuluka kwa kusungunuka, kugawa kufanana ndi kuyanjana kwa HPMC ndi tinthu tating'ono ta simenti.
2. Mphamvu pa kusunga madzi
Kusungidwa kwa madzi ndi chizindikiro chofunikira cha ntchito yamatope, yomwe imakhudza mwachindunji ntchito yomanga ndi khalidwe pambuyo poumitsa. The apamwamba fineness wa HPMC, kwambiri wogawana anagawira particles ali mu matope, amene akhoza kupanga wandiweyani madzi posungira chotchinga, motero bwino kwambiri kusungirako madzi matope. Kuphatikiza apo, HPMC yopangidwa bwino imasungunuka mwachangu ndipo imatha kusunga madzi kale, zomwe zimakhala zopindulitsa kwambiri pakumanga kotentha kwambiri kapena kopanda madzi kwambiri.
Komabe, fineness mopitirira muyeso kungachititse HPMC kuti agglomerate pamene abwera kukhudzana mofulumira ndi madzi, zimakhudza ngakhale kugawa kwake mu matope, potero kuchepetsa kwenikweni madzi posungira kwenikweni. Chifukwa chake, zofunikira zenizeni zogwiritsira ntchito ziyenera kuganiziridwa mozama posankha zabwino za HPMC.
3. Kukhudza kugwira ntchito
Workability amatanthauza ntchito yomanga matope, omwe amagwirizana kwambiri ndi fluidity ndi thixotropy wa matope. HPMC particles ndi fineness apamwamba akhoza kupanga yunifolomu colloid dongosolo mu matope pambuyo Kutha, amene amathandiza kusintha fluidity ndi lubricity wa matope, motero kuwongolera workability. Makamaka pomanga makina, HPMC yapamwamba kwambiri imatha kuchepetsa kupopera mbewu mankhwalawa ndikuwongolera zomangamanga.
M'malo mwake, chifukwa cha pang'onopang'ono Kutha mlingo wa HPMC particles ndi fineness m'munsi, matope akhoza kukhala osakwanira mamasukidwe akayendedwe kumayambiriro siteji kusanganikirana, zimakhudza ntchito yomanga amamva. Kuphatikiza apo, HPMC yokhala ndi tinthu tating'onoting'ono titha kugawidwa mosiyanasiyana mumatope, zomwe zimakhudza magwiridwe antchito.
4. Mphamvu yolimbana ndi ming'alu
Kukaniza mng'alu kumakhudzidwa makamaka ndi kuyanika kwakuya komanso kugawa kwamkati kwamatope. HPMC ndi fineness mkulu akhoza kwambiri wogawana anagawira mu matope kupanga mosalekeza mapadi filimu, amene amachedwetsa evaporation mlingo wa madzi ndi kuchepetsa kuyanika shrinkage wa matope, potero bwino kuwongolera mng'alu kukana.
Kumbali ina, HPMC yokhala ndi fineness yotsika imakonda kupanga madera okhazikika mkati mwa matope chifukwa cha kubalalika koyipa, sangathe kuwongolera kuyanika kwakuya, ndipo imakhala yosakanizika bwino.
5. Mphamvu pa mphamvu
The fineness wa HPMC ali ndi zotsatira zosalunjika pa mphamvu ya matope. HPMC ndi fineness mkulu zambiri kumathandiza simenti kuti hydrate mokwanira chifukwa bwino posungira madzi ndi kubalalitsidwa, potero kuwongolera oyambirira mphamvu ya matope. AnxinCel®HPMC yokhala ndi fineness yotsika ndi yofooka pakusungunuka ndi kugawa, zomwe zingayambitse kusakwanira kwa madzi m'madera akumidzi, potero kumakhudza kufanana kwa mphamvu yamatope.
Kuyenera kudziŵika kuti kwambiri HPMC zili kapena fineness angakhale ndi zotsatira zoipa pa mphamvu, chifukwa mapadi palokha chopereka malire mawotchi zimatha matope, ndipo kwambiri kuchepetsa chiŵerengero cha akaphatikiza ndi simenti.
6. Zolinga zachuma ndi zomangamanga
M'mapulojekiti enieni, HPMC yapamwamba kwambiri nthawi zambiri imakhala yokwera mtengo, koma ubwino wake umawonekera, ndipo ndi yoyenera nthawi zomwe zimakhala ndi zofunikira kwambiri pa kusunga madzi ndi kukana ming'alu. Pazosowa zomanga wamba, kuwongolera bwino kwa HPMC nthawi zambiri kumatha kukhala bwino pakati pa magwiridwe antchito ndi chuma.
Mtengo wa HPMC ndi fineness osiyana amakhudza kwambiri zimatha matope. High-fineness HPMC nthawi zambiri imakhala ndi ntchito yopambana posunga madzi, kugwira ntchito ndi kukana ming'alu, koma mtengo wake ndi wokwera kwambiri ndipo ukhoza kuyambitsa chiopsezo cha agglomeration panthawi ya kusungunuka; low-fineness HPMC ndi yotsika mtengo, koma ili ndi malire pakuwongolera magwiridwe antchito. . Kusankha koyenera kwa AnxinCel®HPMC fineness molingana ndi zofunikira zomanga ndi njira yofunikira yopititsira patsogolo ntchito yamatope ndikuwongolera mtengo.
