2) Muyenera kuwonjezeredwa mwachindunji ku yankho lamadzi abwinobwino, ndibwino kugwiritsa ntchito kupezeka kwa madzi ozizira, mutatha kuwonjezera mu 10-90 mphindi kuti zikuluzikulu (zikopa)
3) Mitundu wamba imatha kusungunuka mutasakaniza ndikumwaza ndi madzi otentha ndikuwonjezera madzi ozizira pambuyo poyambitsa ndikuzizira;
4) Kusungunuka, ngati chodabwitsa cha zigawenga kumachitika, chifukwa chifukwa kusuntha sikukwanira kapena mtundu wamba umawonjezedwa mwachindunji m'madzi ozizira. Pakadali pano, ziyenera kusunthidwa mwachangu.
5) Ngati thovu limachitika mu kusungunuka, amatha kuchotsedwa ndi kuyimilira kwa maola 2 mpaka 12 (nthawi yakeyi amatengera kusasinthika kwa yankho) kapena popewa ndikuwonjezera, kapena powonjezera kuchuluka koyenera.

5 hydroxypropyl methl cellulose mu voliyumu ya punty ufa?
Hpmc pogwiritsa ntchito kuchuluka kwake, ndi nyengo yotentha, kutentha, putty ufa wa plam ndi zofunikira za makasitomala za mtundu wina, ndipo pamakhala zosiyana pozungulira, nthawi zambiri zimakhala pakati pa kilogalamu 4-5.

6. Kodi mawu oyenera a hydroxypropyl ndi chiyani methyl cellulose?
Mafuta a putty nthawi zambiri amatha 100000 amatha kukhala okwera, mpaka 150000 zabwino, ndipo HPMC ndi yofunika kwambiri ndikusungidwa kwamadzi, kenako ndikusungidwa kwamadzi, kenako ndikusungidwa. Mu ufa wa putty, bola ngati kusungira kwamadzi ndikwabwino, mawonekedwe owoneka bwino (7-8)

7. Kodi zida zazikulu za hydroxypypyl ndi methyl cellulose?
HPMC Main Statics: Woyeretsa thonje, chloromethane, ma propylehane oxide, zopangira zina, mapiritsi alkali toluene.

8. Hydroxypropyl methl cellulose pogwiritsa ntchito ufa wa putty, ngati ukulu wake, kaya ndi mankhwala?
Mu ufa wa putty, wokulirapo, kusungidwa kwamadzi ndikumanga kachitatu. Kukula, cellose imatha kufotokozedwa kuti iyimitsidwe, kotero kuti yankho limakhala yunifolomu ndikuwongolera udindo wotsutsa. Kusungidwa kwamadzi: Pangani utoto ufa wowuma pang'onopang'ono, ogwiritsa ntchito imvi ya Exilary Imvi pazinthu zomwe zimachitika. Ntchito Yomanga: Mafuta a cellulose, amatha kupanga ufa wanu ali ndi ntchito yabwino. HPMC sitenga nawo mbali pamavuto aliwonse, koma imangochita zinthu zothandiza.

9.hydroxypypyl methyl cellulose sialic cellulose ether, ndiye kuti siayic?
M'malingaliro a sing'anga, zinthu zomwe sizimatenga nawo mbali pamavuto.
CMC (Carboxymethyl cellulose) ndi Cellulose, motero amakumana ndi calcium ikhale yotsalira ya nyemba.

12 Puti ufa wa dontho ufa ndi hydroxypropyl methyl cellulose ubale?
Ngati HPMC siyisunga madzi osauka, idzayambitsa ufa.

13 hydroxypyl methl cellulose pogwiritsa ntchito ufa wa putty, putty ufa chifukwa chiyani?
Hpmc mu ufa wa putty, wokulirapo, kusungidwa kwamadzi ndikumanga maudindo atatu, zomwe zimayambitsa kuwira:
1.) Madzi ambiri amawonjezeredwa.
2.) Pansi pamunsi siuma youma, kenako ndikumatula pamenepo, zomwe ndizosavuta kufinya.

14. Kodi pali kusiyana kotani pakati pa ozizira ozizira ndi kutentha kwa Hydroxypyl Methyl cellulose popanga?
Mtundu wozizira wa HPMC Uply Inform Treen chithandizo cha Glymoxal pamtunda, kuyika m'madzi ozizira msanga, koma osasungunuka, kudzipatuka, kumathetsedwa. Mtundu wa thermosololuuble sunakhalepo wothandizidwa ndi Glyloxal. Kuchuluka kwa glyloxal ndi kwakukulu, kubalaku kumakhala kofulumira, koma mamasukidwe amasachedwa, kuchuluka kwake ndikochepa, m'malo mwake.

15. Kodi ndi chiyani za hydroxypropyl meth cellouse?
HPMC yopangidwa ndi njira yosungunulira imapangidwa ndi isoene ndi isopropyl mowa. Ngati kusamba sikwabwino kwambiri, padzakhala kukoma kotsalira. (Kuchira kwa Neotrashition ndiye njira yofunika ya fungo)

16. Momwe mungasankhire ma hydroxypropyl methl celyilose yogwiritsa ntchito mosiyanasiyana?
Mafuta a Thitte: Zofunikira za madzi
Matope wamba a simenti: kusungidwa kwamadzi kwakukulu, kutentha kwambiri mpaka kukana, ma vidiwo pompopompo (olimbikitsidwa: 75ax15000000)
Kugwiritsa ntchito guluu: Zogulitsa pompopompo, mafayilo apamwamba. (Chipangizo Chotsimikizidwa: 75ax200000s)
Matope a gypsum: kusunthira kwamadzi kwakukulu, pakati komanso mafayilo otsika, mamasukidwe nthawi yomweyo (olimbikitsidwa: 75ax75000)

17. Kodi dzina la hydroxypropyl ndi chiyani methyl cellulose?
HPMC kapena MHPC Alias ​​hydroxpyl methy cellose, cellulose hydroxypropyl etheryl ether.

18. Kodi pali kusiyana kotani pakati pa hydroxypropyl methy cellose ndi MC?
MC ndi methyl cellulose, woyeretsedwa atalandira chithandizo cha alkali, methane chloride ngati ether etherction, kuphatikiza kwa cellulose, ndi ya ether ether ether.
. Nthawi zambiri, kuchuluka kwake ndi kwakukulu, kukoma mtima ndikochepa, mawonekedwe osungirako madzi ndi okwera, kuchuluka kwa ma vinyo ndi kukongola kwa tinthu tating'onoting'ono. Methyl cellulose ndi hydroxypropyl methy cellulose pa cellulose yoposa ma cellulose okwanira ma cellulose angapo ali ndi kuchuluka kwa madzi.
.
(3) Kusintha kwa kutentha kudzakhudzanso ndalama zosunga madzi za methyl cellulose, nthawi zambiri, kutentha kwa madzi. Ngati kutentha kwa matope kumapitilira madigiri 40, kusungira kwamadzi kwa methyl cellulose kudzakhala koopsa kwambiri, komwe kumakhudza kwambiri zogwirizana ndi matope.
. Kutsatira pano kumatanthauza mphamvu yotsatsira yomwe imamuwona pakati pa chida ndi khoma gawo la wogwira ntchito, ndiye kuti, kusweka kwa matope. Kutsatira ndi kwakukulu, kukana kwa matope ndi kwakukulu, mphamvu zofunidwa ndi ogwira ntchito pakugwiritsa ntchito nthawi zambiri zimagwiritsidwanso ntchito ndizokulirapo, ndipo zomanga za matope ndizosauka.
