Maukadaulo aukadaulo wa hydroxypropyl methylcellulose (hpmc)

Hydroxypropyl methyl cellulose (hpmc) ndi cellulose yopanda ionic ense ogwiritsidwa ntchito kwambiri pomanga, mankhwala, chakudya, zokutira ndi mafakitale ena. Mphamvu zake zapadera ndi zamankhwala zimapatsa mwayi wokhazikika komanso kugwira ntchito moyenera kwambiri. Ndi kufuna kwake kwa kutentha kwambiri, kutentha kwambiri kukana ndi kusintha kwaukadaulo wa HPMC kwadzakhala hoppot.

1. Zoyambira za HPMC

HPMC ili ndi madzi abwino osungunuka, kukula, mawonekedwe a filimu, emulsifying, kukhazikika komanso kusakhazikika. Pansi pa kutentha kwambiri, kusungunuka, minyewa ya nthochi ndi zachinyengo za HPMC idzakhudzidwa, choncho kukhathamiritsa kwaukadaulo wapamwamba kwambiri ndikofunikira pakugwiritsa ntchito kwake.

2. Makhalidwe Akulu a HPMC pansi pa kutentha kwambiri

Miyala yotentha

HPMC imawonetsa nyengo yapadera ya mipata yamphamvu kwambiri pamtunda wapamwamba. Kutentha kukayamba kusiyanasiyana, mafayilo a HPMC yankho la HPMC lidzachepa ndipo mitsinje idzachitika pamtunda wina. Izi ndizofunikira makamaka popanga zomangira (monga matope a simenti, odzilimbitsa okha) komanso makampani ogulitsa zakudya. Mwachitsanzo, mu kutentha kwambiri madera, hpmc kumatha kupereka madzi abwino osasungidwa ndikubwezeretsanso madzi pambuyo pozizira.

Kutentha Kwambiri

HPMC ili ndi kukhazikika kwa matenthedwe ndipo sikophweka kuwola kapena kutsutsa kutentha kwambiri. Nthawi zambiri, kukhazikika kwake kumakhudzana ndi kuchuluka kwa malo olowa m'malo mwa polymerization. Kudzera mu kusintha kwa mankhwala kapena kukhathamiritsa, kukana kwake kutentha kumatha kusintha kuti lithe kukhalabe ndi zinthu zabwino komanso zamagetsi mu kutentha kwambiri.

Kukana Mchere ndi Alkali kukana

Mu malo otentha kwambiri, alkalis amakhala ndi ma elecrolyte, ma electrolyte, makamaka alkali kukana, zomwe zimapangitsa kuti ntchito yomanga igwiritsidwe ntchito muyezo wa simenti ndikukhazikika pakapita nthawi yayitali.

Kusungidwa kwamadzi

Kutentha kwamphamvu kwamadzi kwa HPMC ndi gawo lofunikira pakugwiritsidwa ntchito kwake pomanga. Kutentha kwakukulu kapena malo owuma, hpmc kumatha kuchepetsa mosamalitsa madzi, kuchepetsera njira zomangira, ndikuwongolera kuwongolera zomangamanga, potero kuchepetsa m'badwo wa ming'alu ndikusintha mtundu womaliza.

Pamaso ndi kutanthauzira

Pansi pa kutentha kwambiri, hpmc imatha kukhalabe ndi emulsization yabwino komanso kukhazikika, kukhazikitsa zokutira, ndikugwiritsidwa ntchito kwambiri, zojambula, zakudya, chakudya ndi minda ina.

3. HPMC Moteni kutentha makina

Poyankha zofuna za kutentha kwambiri, ofufuza ndi mabizinesi apanga matekino osiyanasiyana a HPMC kukonza kutentha kwake kutentha komanso kukhazikika kwa ntchito. Makamaka kuphatikiza:

Kuchulukitsa kuchuluka kwa zolowa m'malo

Mulingo wa zolowa m'malo (DS) ndi molar zolowetsa (ms) ya HPMC imathandiza kwambiri pokana kutentha kwake. Powonjezera kuchuluka kwa matenda a hydroxypyl kapena methoxy, kutentha kwake miyala kumatha kuchepetsedwa bwino ndipo kukhazikika kwake kwa kutentha kwake kumatha kusintha.

Kusintha kwa Copsolymerization

Copsolmerization ndi ma polima ena, monga kuphatikiza kapena kuphatikizira mowa wa polyvinyl acid (Pal), etc.

Kusintha kolumikizana

Kukhazikika kwa matenthedwe ku HPMC kumatha kusintha ndi mankhwala olumikizana ndi mankhwala kapena kutsatsa kwakuthupi, kumapangitsa kuti ntchito yake ikhale yokhazikika pansi pa kutentha kwambiri. Mwachitsanzo, kugwiritsa ntchito kusinthidwa kwa silika kapena pourerethane kumatha kukonza kutentha kwa kutentha komanso mphamvu yamakina ya HPMC.

Kusintha kwa Nanocomyoposite

M'zaka zaposachedwa, kuwonjezera kwa nanomatadium, monga nano-silicon dioxide (sio₂Ndipo nano-cellulose, imatha kukulitsa kutentha kwa kutentha ndi makina a HPMC, kuti ithe kukhalabe ndi miyambo yabwino yopanda kutentha kwambiri.

4. HPMC Kutentha Kwambiri Kugwiritsa Ntchito

Zipangizo Zomanga

Pomanga zida monga matope owuma, matontheki omata, ndi khoma lopanda kanthu, ndikusintha matekeyo moyenera magwiridwe antchito ambiri, kuchepetsa kupindika, ndikusintha chitetezo chamadzi.

Makampani Ogulitsa Chakudya

Monga chowonjezera cha chakudya, hpmc chitha kugwiritsidwa ntchito mu madzi ophika kutentha kwambiri kuti muchepetse kusungidwa kwamadzi komanso kukhazikika kwa zinthu kwa zakudya, kuchepetsa kuchepa kwa madzi, ndikusintha.

Gawo Lachipatala

M'makampani opanga mankhwala, HPMC imagwiritsidwa ntchito ngati piritsi yokutidwa ndi kusungidwa ndi kusungitsa kuti musinthe kugwiritsa ntchito mankhwala osokoneza bongo a mankhwala, kumasula mankhwala, ndikuwongolera bioavailability.

Kubowola Mafuta

HPMC imatha kugwiritsidwa ntchito ngati chowonjezera cha mafuta amafuta amadzimitsa kutentha kwambiri kwa mabowo amadzimadzi, pewani bwino khoma, ndikusintha mabowo.

Hpmc Ili ndi miyala yamtengo wapatali yamatenthedwe, kutentha kwambiri kutentha, alkali kukana ndi kusungidwa kwamadzi kumatentha kwambiri. Kuzunza kwake kwa kutentha kumatha kusintha pogwiritsa ntchito mankhwala a mankhwala, kusintha kwa porsolymerization, kusintha kolumikizana ndi kusintha kwa nano-comprote. Imagwiritsidwanso ntchito kwambiri m'mafakitale ambiri monga zomanga, chakudya, mankhwala, ndi mafuta, osonyeza msika wamkulu ndi ntchito. M'tsogolo, pofufuza ndi chitukuko cha zinthu zochulukirapo za HPMC, ntchito zambiri m'matenthedwe otenthetsera kwambiri zidzakulitsidwa.
