Kodi HPMC imatha kusungunuka m'madzi otentha?

HPMC (hydroxypypyl methylcellulose) imagwiritsidwa ntchito kawirikawiri pa cellulose, zogwiritsidwa ntchito, mankhwala, chakudya ndi mafakitale ena. Amapezeka ndi kusintha kwa mankhwala a cellulose. Makhalidwe ake amathandizira kuti apange yankho lalikulu m'madzi ndipo ali ndi kusungunuka kwina.

Kodi HPMC imatha kusungunuka m'madzi otentha?
HPMC imatha kusungunuka m'madzi otentha, koma kukhulupirika kwake kumagwirizana kwambiri ndi zinthu monga kutentha, kutentha kwa madzi osokoneza bongo, komanso kuchuluka kwa kusintha. Nthawi zambiri, nthawi zambiri, hpmc imatha kusungunuka pa kutentha kwa firiji, koma kusinthika kwa chilengedwe kumatha kutentha kwambiri.

1. Kuthana ndi makina
Makina a HPMC kusungunuka m'madzi makamaka kumadalira hydrophilicity ya hydrochility wa magemu ndi methyl ndi magulu a propyl m'mamolekyulu ake. Mamolekyu amadzi amatha kuyanjana ndi ma hydroxyl ndi magulu a methyl mu mamolekyu a HPMC kudzera pamabwalo a hpmc kudzera pamayendedwe a hydrogen, kuti unyolo wosungunuka umasungunuka ndipo pamapeto pake njira yodziwira. Chifukwa chake, HPMC ili ndi madzi abwino amadzi.

2. Mphamvu yofatsa kutentha pa solubility ya HPMC
Kusungunuka kwa HPMC kamachuluka ndi kutentha kwambiri. Pansi pa kutentha kwambiri, mphamvu ya kinetic yamadzi imachuluka, ndipo amatha kulumikizana bwino ndi magulu a hydrophilic mu HPMC mamolekyulu, potero amatha kuthamangira kusungunula kwawo. Makamaka kwa HPMC yokhala ndi zolemera zapamwamba, madzi otentha amatha kuwathandiza kusungunula mwachangu kwambiri.

Komabe, kusungunuka kwa HPMC sikungotengera kutentha, komanso njira yake yosinthira. Gulu losiyanasiyana la mankhwala mu HPMC Molekyu ya HPMC imakhudza kuwonongeka kwa madzi ndi kusungunuka. Mwachitsanzo, HPMC yokhala ndi ma hydroxypyl omwe ali ndi Hydrophilicity motero amasungunula mwachangu m'madzi.

3. Mphamvu ya kutentha kwambiri pathanzi
Kutentha kwambiri, kufalikira kwa HPMC idzapititsidwa kwambiri. Makamaka, pamlingo wa 60 ° C mpaka 90 ° C, kusinthika kwachilengedwe kwa HPMC kuli bwino. Izi ndichifukwa madzi otentha amatha kuwononga maula aumwini pakati pa mamolekyulu, amalola mamolekyulu amadzi kuti alowe mu mawonekedwe a HPMC mwachangu, potero amalimbikitsa chikhumbo chake.

4. Mavuto omwe angakumane nawo patha
Ngakhale hpmc imatha kusungunuka m'madzi otentha, ngati matenthedwe ali okwera kwambiri, hpmc mu yankho amatha kuwonongeka kwambiri kapena kusintha kwa kapangidwe kake, makamaka mukakhala ndi kutentha kwambiri kwa nthawi yayitali. Izi zitha kukhudza mamasukidwe ake komanso ntchito yake, makamaka mu madera ena ogwiritsa ntchito, kusinthaku kungakhale kosangalatsa pazinthu zomaliza.

Ngati kutentha kwamadzi kunawonjezeredwa munthawi yofananira ndi kukwera kwambiri, hpmc ufa ukhoza kupanga tinthu tating'onoting'ono m'madzi, zomwe zimapangitsa kuti zinthu zosakwanira. Chifukwa chake, kuti muwonetsetse kuti chisinthiko cha HPMC, nthawi zambiri chimalimbikitsidwa kugwiritsa ntchito madzi ofunda ndikutengera njira zoyenera zolimbitsa thupi kapena zothandizirana ndi akupanga.

Zitsanzo za kusinthika kwa madzi otentha a HPMC
Pogwiritsa ntchito ntchito, madzi otentha a HPMC amagwiritsidwa ntchito nthawi zambiri. Mwachitsanzo. Pokonzekera simenti slurry kapena matope, hpmc imatha kuthandizira kukonza magwiridwe antchito komanso kupewa kusweka.

M'makampani opanga mankhwala, hpmc amagwiritsidwa ntchito kwambiri popanga othandizira omasulidwa ndi mapiko a makapiso. Chifukwa cha kusalala kwake kwamadzi, hpmc kumatha kusungunuka pang'onopang'ono mu thupi la munthu ndikumasulidwa mankhwala. Munjira iyi, kutentha kwa madzi ndi kusinthika kwa HPMC kumatenga mbali yofunika.

M'makampani azakudya, hpmc, monga chowonjezera cha chakudya, nthawi zambiri chimagwiritsidwa ntchito ngati thiccener, elsilfair, etc. amatha kupereka mawonekedwe am'madzi ndi kapangidwe kake ka chakudya.

HPMC imatha kusungunuka m'madzi otentha, ndipo kusungunuka kwake kumakhudzana ndi kutentha kwa madzi, mawonekedwe a HPMC, kuchepetsedwa kwa mankhwala ndi mankhwala. Pa kutentha kwambiri, kusinthika kwa chizolowezi kumathamanga kwambiri, nthawi zambiri pamlingo wa 60 ° C mpaka 90 ° C, kusunthika kumatheka bwino. Mukamagwiritsa ntchito madzi otentha kuti asungunuke hpmc, ndikofunikira kumvetsera kutentha kwa madzi ndi nthawi yofatsa kuti mupewe kutentha kwambiri pakuchita kwake.
