Mafakitale a mafakitale hydroxypropyl methylcellulose (hpmc)

Mafakitale a mafakitale hydroxpyl methylcellulose (hpmc) ndi mankhwala osokoneza bongo opangidwa ndi ma celluuse opangidwa kuchokera ku cellulose wachilengedwe pambuyo posinthira mankhwala. Zida zake zazikulu ndi thonje kapena zamkati zamkati, ndipo imakonzedwa pogwiritsa ntchito njira zingapo monga kupembedza, kutsuka, kutsuka. Chifukwa HPMC ili yabwino kwambiri, kuyimitsidwa, kusonkhana, kugwiririra, emulsization, zopangira mafilimu, zothandizira, zodzola, zodzola, mankhwala ndi minda ina.

1. Makhalidwe oyambira a HPMC
Kusungunuka ndi kukhazikika
HPMC imasungunuka m'madzi ozizira ndi ena okhazikika ndipo ili ndi madzi abwino. Ndizosathuka m'madzi otentha, koma imatha kupanga gel wa gel, ndipo njira yosungunuka imawoneka bwino kwambiri komanso kukhazikika. Kuphatikiza apo, HPMC imakhala ndi bata yabwino kwambiri ya pH, ndipo nthawi zambiri imakhala yokhazikika mumitundu ya 3 ~ 11.

Kusungidwa kwamadzi komanso kukula
HPMC ili ndi madzi okwanira kwambiri ndipo amatha kupewa kutaya madzi. Katunduyu amapangitsa kuti ikhale ndi gawo lofunikira mu gawo la simenti m'gawo lomanga, kukonza magwiridwe antchito ndikupewa kusokonekera. Kuphatikiza apo, HPMC ndi yothandiza kwambiri, ndipo njira yake yothetsera magazi imatha kuwonetsera mawonekedwe otsika otsika.

Katundu wopanga makanema
HPMC imatha kupanga filimu yolimba komanso yowoneka bwino padziko lapansi, yolimbana ndi mafuta abwino ndi anti-enzyme katundu. Katunduyu amazigwiritsa ntchito kwambiri zokutira, zokumba zamankhwala ndi minda ina.

Zochitika zapamwamba
HPMC ili ndi emulsization yabwino komanso yoteteza colloid, ndipo imatha kusungunuka mokhazikika mu makina ochulukitsa, potero ndikuwongolera yunifolomu ndi kukhazikika kwa dongosololi.

2. Ntchito ya HPMC
Kupanga kwa mafakitale a HPMC-GPMC makamaka makamaka kumaphatikizapo njira zotsatirazi:

Kukonzekera Kwa Zinthu
Kugwiritsa ntchito cellulose yachilengedwe (thonje kapena mitengo yamitengo) ngati raw zinthu, imamizidwa mu alkalini njira yothandizira kulandira mankhwalawa ndikuyambitsa ma cellulose molecular unyolo.

Kuzindikira
Pamaziko a ma cellulid cellulose, othandizira (monga methyl chloride ndi ma proveyne oxide) amawonjezeredwa, ndipo mayesedwe amachitika pamtunda wina ndi ma hydroxygyulose.

Chithandizo
Chochita chomwe chizichita chimasambitsa, kuchapa, kuyanika ndi kuphwanya ndondomeko zopangira ma viscosies osiyanasiyana ndi zoyera kuti zitheke zofunikira pakugwiritsa ntchito.

3.. Madera akulu a HPMC
Makampani omanga
HPMC ndi gawo lofunikira mu matope owuma, matayala omata, putty ufa ndi zokutira zakuda. Kusungidwa kwake ndi madzi osungirako zinthu kumathandiza kwambiri kukonza magwiridwe antchito, kupanga zolimbitsa nyumba kukhala zolimba komanso zosavuta kugwira ntchito.

Zovala ndi zojambula
HPMC itha kugwiritsidwa ntchito ngati thicker, wobayira komanso kusungitsa zokutira kuti apereke zogwirizana, sinthani kuwononga magwiridwe antchito ndikuwonjezera zida zovomerezeka.

Mankhwala ndi chakudya
M'makampani opanga mankhwala, hpmc nthawi zambiri amagwiritsidwa ntchito kukonzekera zigawo ndi zomatira mapiritsi a mankhwala opanga mankhwala, ndipo amagwiritsidwanso ntchito pakukonzekera kwa mamasulidwe. Pakudya chakudya, hpmc imagwiritsidwa ntchito ngati emulsifier, thicldener ndi okhazikika mu zakudya zosiyanasiyana.

Mankhwala tsiku lililonse
HPMC imagwiritsidwa ntchito kwambiri mu shampoo, zinthu zosamalira khungu ndi zinthu zina, zopereka zolimbitsa thupi, kukula ndi luso labwino kwambiri.

4. Ubwino ndi chitukuko cha mafakitale a mafakitale a gpmc
Ubwino
Mafakitale a mafakitale ali otetezeka komanso ochezeka, ali ndi magwero osiyanasiyana, ndipo ali ndi ntchito zosiyanasiyana. Itha kukwaniritsa zosowa zamakono zamakono zothandiza, zobiriwira komanso zodziwika bwino. Nthawi yomweyo, kugwiritsa ntchito kwake ndizochepa koma zotsatira zake ndizofunikira, ndipo zimakhala ndi mtengo wokwera mtengo kwambiri.

Kuchita Chitukuko
Ndi chitukuko cha nyumba zobiriwira, zofunda zachilengedwe ndi zofunda zapamwamba, kufunikira kwa HPMC kudzakulabe. Nthawi yomweyo, kupanga kwa HPMC kukukonzekera kuwongolera kwakukulu, kugwiritsa ntchito kotsika komanso kuipitsa kochepa, kukonzanso zabwino zake zachuma ndi chilengedwe.

Mafakitale a mafakitale a mafakitale a methylcelluse akhala ofunikira komanso ofunikira othandizira pantchito zamafakitale ndi mphamvu zake zolimbitsa thupi ndi mankhwala. M'tsogolomu, popititsa patsogolo ukadaulo ndi kukula kwa magawo a ntchito, ziyembekezo za msika HPMC zimatalika. Pofufuza mosalekeza ndi chitukuko ndi kusankhananso, ntchito yake idzayenda bwino kuti ikwaniritse zofunika kupeza zofunika pa ntchito zosiyanasiyana.
