Kodi mukudziwa hydroxypropyl methylcellulose?

Hydroxypropyl methylcellulose imagwiritsidwa ntchito kwambiri pantchito yomanga. Lero, ndikuwonetsa njira yosungunula ya hydroxypropyl methylcellulose komanso momwe ndingaweruzire mtundu wa hydroxypropyl methylcellulose.

Njira yothetsera hydroxypropyl methylcellulose:

Zitsanzo zonse zikhoza kuwonjezeredwa kuzinthu mwa kusakaniza kowuma;

Pamene ikufunika kuwonjezeredwa mwachindunji ku kutentha kwabwino kwamadzimadzi, ndi bwino kugwiritsa ntchito mtundu wobalalika madzi ozizira, ndipo ukhoza kuwonjezereka mkati mwa mphindi 10-90 mutawonjezera;

Mutatha kuyambitsa ndi kumwaza ndi madzi otentha amtundu wamba, onjezerani madzi ozizira ndikugwedeza kuti musungunuke;

Ngati pali agglomeration ndi ❖ kuyanika panthawi ya kusungunuka, amayamba chifukwa chosakwanira kugwedeza kapena kuwonjezera mwachindunji madzi ozizira ku mbiri wamba. Panthawi imeneyi, iyenera kugwedezeka mwamsanga;

Ngati ma thovu amapangidwa panthawi ya kusungunuka, akhoza kusiyidwa kuti aime kwa maola 2-12 (kutsimikiziridwa malinga ndi kugwirizana kwa yankho) kapena kuchotsedwa ndi kuthawa, kupanikizika, ndi zina zotero, komanso kuchuluka koyenera kwa defoamer kungawonjezedwe.

Momwe mungaweruzire mtundu wa hydroxypropyl methylcellulose mosavuta komanso mwachilengedwe

Kuyera: Malinga ndi kuyera kwake, ndizosatheka kudziwa ngati HPMC ingagwiritsidwe ntchito nthawi zonse, ndipo ngati zowonjezera zoyera ziwonjezeredwa pakupanga, zidzakhudzanso ubwino wake. Komabe, zinthu zokhala ndi zoyera zabwino nthawi zambiri zimakhala zabwino.

Ubwino: HPMC nthawi zambiri imakhala ma mesh 80, mauna 100, mauna 120, kuwongolera kumakhala bwinoko.

Transmittance: ikani HPMC m'madzi kuti mupange colloid yowonekera, ndikuwona kufalikira kwake. Kuchuluka kwa transmittance, zinthu zochepa zosasungunuka m'madzi. Nthawi zambiri, transmittance ndi bwino ofukula riyakitala ndi yopingasa riyakitala. Ndi zoipa mu ofukula riyakitala, koma sangathe kufotokoza kuti khalidwe la mankhwala opangidwa ndi ofukula riyakitala ndi bwino kuposa ya yopingasa riyakitala.

Kukoka kwapadera: Nthawi zambiri, chifukwa cha kuchuluka kwa hydroxypropyl, mphamvu yosunga madzi ndi yabwino.
