Kodi HPMC imatha kusungunuka m'madzi otentha?

HPMC (hydroxypypyl methylcelulose) ndi polymer courmer yomwe imagwiritsidwa ntchito mu mankhwala, chakudya ndi malonda. Amapangidwa kuchokera ku cellulose yachilengedwe yosinthika ndipo imasungunuka madzi ndi kukhazikika. Koma ngati HPMC itha kusungunuka m'madzi otentha, imafunikira kuwunikiridwa kuchokera ku ubale pakati pa zosinthika ndi kutentha kwa madzi.

1. Makhalidwe osungunuka a HPMC
HPMC ndi chimbudzi chosasungunuka chamadzi chomwe chimatha kusungunuka m'madzi ozizira ndikupanga yankho lowonekera kapena lolora. Kusungunuka kwake kumakhudzidwa kwambiri ndi kutentha, komwe kumawonekeranso m'mbali zotsatirazi:
Kutentha kochepa kutentha: M'madzi ozizira (nthawi zambiri pansi pa 40 ° C), ma cell a hpmc amatha kuyamwa madzi mwachangu ndikutupa pang'onopang'ono kuti apange njira yothetsera yunifolomu.
Kuchepetsa Madzi Otentha: HPMC sikununkhidwe mu kutentha kwambiri kumadzi, koma kumatha kubalalika kuti apange kuyimitsidwa. Madzi akamawaza kutentha koyenera, tinthu tating'onoting'ono timayamba kusungunuka.

2. Kuthana kwa kusungunuka m'madzi otentha
Kuchita kwa HPMC m'madzi otentha kumagwirizana kwambiri ndi kutentha ndi njira yothetsera:
Osasungunuka mwachindunji m'madzi otentha: kutentha kwambiri (nthawi zambiri kumatentha 60 ° C) malo, hpmc tiyeni kutaya pang'onopang'ono ma netiweki. Izi zimatchedwa "miyala yotentha", ndiye kuti, hpmc mamolekyulu ophatikizika m'madzi otentha kudzera mu gawo la hydmoleclan.
Njira Yoyenera Yokhumudwitsa: Onjezani HPMC kumadzi otentha ndikusunthira bwino kuti apange bata. Pamene kutentha kumatsikira, mafuta owotchera amachotsedwa, ndipo tinthu tating'onoting'ono titenga madzi kachiwiri ndikusungunuka pang'onopang'ono.

3. Njira zosungunuka pamapulogalamu othandiza
Pofuna kusintha kusungunuka kwamphamvu kwa hpmc ndi kufanana kwa yankho, njira zotsatirazi zimagwiritsidwa ntchito:
Njira yotentha komanso yozizira yosakanikirana ndi HPMC kumadzi otentha pafupifupi 70
Kuwuma kwa ufa woyamba kubadwa: Sakanizani hpmc ndi ufa wina mosavuta (monga shuga), ndipo pang'onopang'ono onjezani madzi ozizira kuti asungunuke, omwe angakulitse liwiro lofalikitsa.

4. Kusamala
Pewani kutentha kwambiri: hpmc imatha kutaya kusalala pamwamba pa kutentha kwake (nthawi zambiri pakati pa 60-75 ° C).
Muziyambitsa bwino: onetsetsani kuti tinthu tambiri obalalitsidwa bwino mukamawonjezera madzi kuti mupewe mapangidwe a zotupa zokhumudwitsa.

HPMC siyisungunuke mwachindunji m'madzi otentha, koma imatha kubalalitsidwa m'madzi otentha kuti apange kuyimitsidwa, komwe kumasungunuka pambuyo pozizira. Chifukwa chake, njira yolondola yosinthira ndiyofunikira pakugwira ntchito kwake. Pazogwiritsa ntchito, zosungunuka ziyenera kusinthidwa malinga ndi zofunikira zina zoti athere nawo kwathunthu, kukhazikika kapena kukhazikika kwa makanema.
