Hydroxypropyl methylcellulose - yankho

Mafakitale a mafakitale hydroxpyl methl celyolose ndi matope kuti asiyanitse ma viction

1.

Chifukwa: Makutu otsika, ngakhale kusungidwa kwamadzi osawuka, koma kuphatikiza kwa matope.

2. Maonekedwe otsika ndi otsika: 20,000-40000 Makamaka guluu, ochititsa chidwi, matope otsutsa, osokoneza bongo, ofuula, amangiriza matope, etc.

Cholinga: Ntchito zomanga zabwino, madzi ochepa, kachulukidwe kwambiri wa matope.

1, kodi kugwiritsa ntchito kofunikira kwa hydroxypropyl methl cellulose (hpmc)?

HPMC imagwiritsidwa ntchito kwambiri pazomangira, zokutira, matekenti, matenti, mankhwala, chakudya, zovala, zopangira, fodya komanso mafakitale ena. HPMC ikhoza kugawidwa mu: Grace Womanga, kalasi ya chakudya ndi kalasi ya zamankhwala pogwiritsa ntchito. Pakadali pano, ambiri mwa omanga nyumba, mu kalasi yomanga, matope a ufa ndi akulu, pafupifupi 90% amagwiritsidwa ntchito popanga ufa, ena onse amagwiritsidwa ntchito popanga matope a simenti ndi gulu.

2, hydroxypropyl methy cellulose (hpmc) amagawidwa kangapo, kusiyana kwake ndi chiyani pakugwiritsa ntchito kwake?

HPMC imatha kugawidwa kukhala mtundu wa yankho ndi njira yotentha, zinthu pompopompo, m'madzi ozizira msanga, nthawi ino madzi alibe mafayilo m'madzi, palibe chisinthiko chenicheni. Pafupifupi mphindi ziwiri, mawike amadzimadzi amawonjezeka pang'onopang'ono, ndikupanga mafilimu owonekera. Zinthu zotentha zotentha, m'madzi ozizira, zimatha kusungidwa mwachangu m'madzi otentha, pomwe kutentha kumatsika mpaka kutentha, mpaka mapangidwe a colous owoneka bwino. Njira yothetsera yotentha imatha kugwiritsidwa ntchito mu ufa ndi matope, m'matola owombera madzi ndi utoto, padzakhala gulu la gulu, sizingagwiritsidwe ntchito. Model Solution Model, njira zingapo zogwiritsira ntchito ndizachilendo pang'ono, kutopa ndi ufa ndi matope, komanso mumatopi odzichepetsa, onse angagwiritse ntchito, popanda zomwe zikugwirizana.

3, hydroxypropyl methy cellulose (hpmc) njira zimakhala ndi izi?

- Njira: Njira Yotentha Madzi: Chifukwa HPMC sinasungunuke m'madzi otentha, mobwerezabwereza hpmc imatha kubadwa m'madzi otentha, kenako kusungunuka mwachangu atakhazikika, njira ziwiri zofotokozedwa motere:

1) Ikani madzi otentha mu chidebecho ndikutenthe mpaka pafupifupi 70 ℃. Pang'onopang'ono onjezani hydroxypypyulloulose pansi pang'onopang'ono, hpmc adayamba kuyandama pamadzi, kenako pang'onopang'ono amapanga malo osalala, pansi pabwino kuzizira.

2), onjezani kuchuluka kwa 1/3 kapena 2/3 madzi mu chidebe, ndi kutentha mpaka 70 ℃, malinga ndi njira ya 1), Kukonzekera kwa HPMC, kukonza madzi otentha; Kenako onjezani kuchuluka kwa madzi ozizira kupita ku malo otentha, sakani ndi kuziziritsa kusakaniza.

Njira yosakanikirana: HPMC ufa ndi zigawo zina zambiri zakuthupi, osakanikirana bwino ndi blender, koma osaphika madzi nthawi ino, chifukwa ngodya yaying'ono ija, madzi ayamba kusungunuka nthawi yomweyo. - Mafuta a putty ndi maanja opanga matope omwe akugwiritsa ntchito njirayi. Hydroxypropyl me cellulose (hpmc) imagwiritsidwa ntchito ngati othandizira kukulitsa matope a ufa.

4, kuloza komanso kosavuta motani kudziwa mtundu wa hydroxypropyl methl cellouse (hpmc)?

- Yankho: Komabe, zinthu zabwino zimakhala zoyera kwambiri.

.

. Kufalikira kwa riyakitalay riyakitala nthawi zambiri kumakhala kovuta, koma sikungawonetse kuti mtundu wa riyacy riyacy ndi wabwino kuposa momwe zinthu zokulirapo zimatsimikiziridwa ndi zinthu zambiri.

(4) Mphamvu yokoka: mphamvu yayikulu, yolemera. Kuposa kuchuluka, nthawi zambiri chifukwa cha hydroxypropyl ndiwokwera, hydroxypropyl yomwe ili pamwamba, kenako kusungidwa kwamadzi ndikwabwino.

5, hydroxypropyl methl cellulose (hpmc) mu kuchuluka kwa ufa?

- Yankho: hpmc mu kugwiritsa ntchito kwa mlingo, mwa nyengo, kutentha, calcium phulusa labwino, putty ufa wa formula ndi "zofunika za makasitomala", ndipo pali zosiyana. Nthawi zambiri, makilogalamu asanu ndi asanu. Mwachitsanzo: Beijing putty ufa, makamaka amayika 5 kg; Ku Guizhou, ambiri mwa iwo ndi 5 makilogalamu m'chilimwe ndi 4.5 makilogalamu nthawi yozizira. Kuchuluka kwa Yunnan ndikochepa, nthawi zambiri 3 kg -4 kg ndi zina zotero.

6, Hydroxypropyl Methyl cellulose (hpmc) kuchuluka kwa mafayilo omwe kuli koyenera?

- Yankho: Khalani otopa ndi ufa wa ufa 100,000 Ok, kufunikira kwa matope ndi wamtali, ndikufuna kugwiritsa ntchito zikwi 150 kuti azigwiritsa ntchito. Kuphatikiza apo, gawo lofunikira kwambiri la HPMC ndi kusungidwa kwamadzi, kenako ndikukula. Mu ufa wa putty, bola ngati kusungira kwamadzi ndikwabwino, mafayilo amatsika (7-8,000,000), kusinthika kwa madzi ndikwabwino, pamene zikuwoneka bwino pa 100,000, mafanowo samakhudzanso kusungidwa kwamadzi.

7, hydroxypropyl methl cellulose (hpmc) Kodi ndi ziti zomwe ndi zizindikiro zazikulu zaukadaulo?

Yankho: Hydroxypyl ndi ma visct, omwe ndi omwe ogwiritsa ntchito ambiri amakhudzidwa nazo. Ma hydroxypropyl omwe ali pamwamba, kusungidwa kwamadzi nthawi zambiri kumakhala bwino. Mafayilo, kusungidwa kwamadzi, wachibale (koma osati mtheradi) alinso wabwinoko, komanso mafayilo, mu matope, mu matope a Smenti, amagwiritsa ntchito bwino ena.

8, hydroxypropyl methl cellulose (hpmc) zinthu zazikuluzikulu ndizomwe?

- Yankho: Hydroxypypyl Medielose (HPMC) ya zopangira zazikulu:

9, HPMC pakugwiritsa ntchito ufa wa putty, gawo lalikulu ndi chiyani, ngati chemistry?

HPMC mu ufa wa punty, ndikukula, kusungidwa kwamadzi ndikumanga kwa maudindo atatu. Kukula: Cellulose imatha kufotokozedwa kuti ipange kuyimitsidwa, kotero kuti yankho loti lisunge yunifolomu ndi kutsika gawo lomwelo, kutuluka kwa anti. Kusungidwa kwamadzi: Pangani ufa wa ufa pang'onopang'ono pang'onopang'ono, ash phulusa la calcium munthawi yamadzi. Ntchito Yomanga: Cellulose yachulukitsa mphamvu, imatha kupanga ufa kukhala womanga bwino. HPMC sitenga nawo mbali pamavuto aliwonse, ingogwira ntchito yothandiza. Pangani ufa wowonjeza madzi, pakhoma, ndikukhalanso ndi mankhwala, chifukwa pali m'badwo wa zinthu zatsopano, pansi pa ufa wa pakhomalo, kenako ndikugwiritsanso ntchito zinthu zatsopano (calcium carbonate). Zigawo zikuluzikulu za calcium ufa ndi: CA (o) 2, caom ya cacoum, h2on 2 = zochita.

10, HPMC yopanda Ionic cellulose ether, ndiye kuti sialic?

Yankho: Nthawi zambiri, osagwirizana ndi chinthu m'madzi omwe sachita mawu. Ionanir ndi njira yomwe electrolyte imasungunuka momasuka. Mwachitsanzo, sodium chloride (nacl), mchere womwe timadya tsiku lililonse, umasungunuka m'madzi ndi inozi kuti apange ma iyoium oyenda mwaulere komanso a Nanoride omwe amalipidwa. Mwanjira ina, hpmc m'madzi sizimasungunuka mu ma ionr, koma ilipo ngati mamolekyulu.
