Hydroxypropyl methyl cellulose (hpmc), zopangiralera, ikhoza kukhala thonje kapena zamkati. Ndikofunikira kupangira kale kapena nthawi ya alkization. Kupanga kumachitika ndi mphamvu yamagetsi. Kuwononga mawonekedwe ophatikizika a cellulose kuti muchepetse digiri ya crystallity ndi ma polymerization ndi kuwonjezeredwa pamalopo, potero kuwongolera njira ya ma valilose macrocose mphete ya Glurose.
Hydroxypropyl methyl cellulose (hpmc)imagwiritsidwa ntchito ngati chopangira chopangira kuti apange mafuta, omwe amatha kuzindikira kugwiritsa ntchito shuga yonse, kukonza njira yofiyira, ndikuchepetsa mtengo wa msuzi woponyera madzi. Machitidwe amethyl celluloseali otsimikiza kukhathamiritsa kwa batch, FED-bad-bat-bat-mosalekeza, kupewa mavuto osiyanasiyana monga kuwongolera mawonekedwe a sing'anga ndi kuchepetsedwa; Nthawi yomweyo, zimathandizanso kuwongolera kwa mphamvu. Chifukwa katundu wahydroxypropyl methyl cellulose (hpmc)ndizofanana ndi zosungunulira zina zam'madzi, zitha kugwiritsidwa ntchito ngati wothandizira wa makanema, emulsifier ndi osungunuka m'matumba a latex ndi zokutira zamadzi Katundu ndi kutsatira, ndipo wakhazikika pamavuto acita, kukhazikika kwa asidi ndi alkali, komanso kuphatikizika ndi utoto wachitsulo.
Hydroxypropyl methyl cellulose (hpmc)Imakhala ndi zotsatirapo zabwino kwambiri za zoyera zoyera za polyvinyl. Kuchuluka kwacellulose etherzimachulukitsidwa, ndipo kukana kwa mabakiteriya ndi kukokoloka kumathanso.
Ngakhale mfundo ya kaphatikizidwe ka Hydroxypylll (HPMC) siyovuta, imayamwa, yosiyanasiyana yazovuta, ndikusintha. Malo osiyanasiyana a chikondwerero, zosungunulira, kulekanitsidwa kwa centrifuga, kutsuka ndi kuyanika kumakhudzanso matekinoloje ambiri ndi chidziwitso chokwanira.
Kwa mitundu yosiyanasiyana ya zinthu, malo aliwonse amakhala ndi mikhalidwe yaposachedwa kwambiri, monga kutentha, nthawi, kupanikizika ndi kuyendetsa bwino. Zida zothandizira ndi zida zowongolera ndizodalirika komanso chitsimikizo chopindulitsa kwa dongosolo lokhazikika komanso dongosolo lodalirika.
Machitidwe ahydroxypropyl methyl cellulose:
1. Katundu: Izi ndi ufa woyera, ndipo ndi wopanda mafuta, wopanda mphamvu komanso wopanda mafuta.
2. Zotsatira za madzi: Chifukwa izi zitha kuthira madzi zingapo zokulira zokha. Sungani chigunde chambiri mu matope, gypsum, utoto ndi zinthu zina.
3. Izi zitha kusungunuka m'madzi ozizira kuti apange zosungunulira zowoneka bwino.
4. Kusungunuka mu ortic sodicnts: chifukwa ili ndi majini ena a hydrophobic, izi zitha kusungunuka m'malo ena okhazikika, ndipo zitha kusungunuka mu zinthu zosakanizika zamadzi ndi zinthu zachilengedwe.
5. Mchere Kukana: Popeza izi ndi zopanda mainic komanso zopanda policlerrolyte, zimakhala zokhazikika m'matumba a mchere kapena ma elekiti. Pankhani ya electrolyte kwambiri, imatha kuyambitsa mafupa kapena mpweya.
6. Ntchito Yoyambira: Njira yothetsera matendawa imagwira ntchito.
