Kodi HPMC imakhudza bwanji nthawi ya matope?

Hydroxypropyll methylcellulose (hpmc) ndi zowonjezera zowonjezera pomanga ngati matope, zimapangitsa nthawi yake kukhala ndi nthawi ina. Kumvetsetsa za HPMC pa nthawi ya chivundi kumaphatikizapo kudziteteza mu kapangidwe kake, zokhudzana ndi zigawo zina, komanso njira zonse za matope.

1.Introduction to HPMC:

HPMC ndi polty wopanga kuchokera ku cellulose, wogwiritsa ntchito kwambiri pomanga ngati Thicner, Bander, wogulitsa-Rheology, ndi Rheology okhazikika. Malo ake apadera amapangitsa kukhala owonjezera owonjezera matope.

Nthawi ya matope:

Kukhazikitsa nthawi kumangofika nthawi yomwe imafunikira matope mutaumitsa kusakanikirana ndi madzi. Izi zimaphatikizapo kusintha kwamankhwala angapo, makamaka mankhwalawa, pomwe madzi amakumana ndi simenti tinthu kuti apange phala lomwe pamapeto pake chimakhala.

3.Pact ya HPMC pa nthawi:

Kusungidwa kwamadzi: HPMC imathandizira kusungidwa kwamadzi mu matope popanga filimu yoteteza mozungulira simenti tating'onoting'ono, kuchepetsa kuchepa kwamadzi kudzera mu eapoph. Kupezeka kwa nthawi yayitali kumeneku kumayambira nthawi ya hydration, chifukwa chake akuchedwetsa nthawi.

Kuwongolera Kubwezeredwa: HPMC imatha kukhala ngati yopumira, ndikuchepetsa mphamvu hydration poletsa kulumikizana pakati pa madzi ndi simenti. Kubweza kumeneku kumalola kugwira ntchito bwino komanso kusintha kwa nthawi yokhazikitsa zofunikira zomangamanga.

Kugwiritsa ntchito molimbika: mwa kukulitsa matope ndi kupewa tsankho komanso magazi, hpmc imathandizira bwino. Nthawi yowonjezereka imakhudza nthawi yayitali, chifukwa zimalola kuyikapo kokwanira ndikuphatikiza matope a matope asanafike.

Kukhutiritsa kwa kutentha: HPMC imatha kupangidwa kuti iwonetsetse kutentha kwa kutentha. Pamadzi otsika, amatha kusunga nthawi yokhazikika kwambiri, ndikusinthasintha nyengo yozizira poteteza matope oyambira.
Mlingo ndi kukula kwake: Mphamvu ya hpmc pa nthawi yake ndi mlingo wodalira. Kukhazikika kwa HPMC nthawi zambiri kumayambitsa kubwezeretsa kwakukulu kwa nthawi. Kuphatikiza apo, kukula kwa tinthu kwa hpmc kumatha kusintha kuperekera ndi kugwira ntchito mosintha matongani.

Makina:

Njira ya hydration: hpmc imalumikizana ndi madzi nthawi ya hydration njira, ndikupanga matrix ngati a gel omwe amazungulira tinthu tating'onoting'ono. New Intaneti imachepetsa kusintha kwa madzi ndi ma ayoni ofunikira kwa simenti hydration, ndikuyika nthawi yokhazikika.

Kuyanjana Kwambiri: ma molekyulu a hpmc adsorb pansi pa simenti tinthu tating'onoting'ono, kusintha mapangidwe awo ndikulepheretsa nyukiliya ndi kukula kwa zinthu hydrate. Kulumikizana kotereku kumachepetsa kuchuluka kwa simenti hydration, chifukwa chake kutalikirana nthawi yomweyo.

Kudzaza Pore: HPMC imadzaza ma voids pakati pa tinthu tating'onoting'ono, kuchepetsa kusuntha kwawo ndikulepheretsa mapangidwe a kapangidwe kakang'ono ka malo otentha kwambiri. Kudzaza kuzengereza kumeneku kumapangitsa kuti pakhalebe nthawi yokhazikitsa nthawi yopita patsogolo kwa hydiction.

HPMC imachita mbali yofunikira pakusintha matope kudzera mu matope kudzera mu madzi ake osungirako madzi, makina olamulidwa ndi simenti. Kuzindikira izi ndikofunikira kuti mutseke matope opanga kuti mukwaniritse zofunika kuchita ndi zochitika zachilengedwe pomanga. Monga kafukufuku ndi chitukuko pakupanga zomanga, zikuwunikiranso zina mwa matope a HPMC pa matope a HPMC pa matope omwe amathandizira kumanga njira zokhazikika komanso zolimba.
