Tianai cellulose co., Ltd ndi hydroxypypyl cellulose rpmc wopanga wopanga China, yomwe ili ndi dzina lake labwino kwambiri ku Celelicess® cellUlose.
Kuyang'ana mwachangu pa hydroxypropyl methylcellulose hpmc
Chimodzi, kugwiritsa ntchito kofunikira kwa hydroxypropyl nonth mediese?
HPMC imagwiritsidwa ntchito kwambiri m'magawo omanga, zokutira, matekenti, matenti, mankhwala, chakudya, nsalu, zodzikongoletsera, fodya komanso mafakitale ena. HPMC imatha kugawidwa m'makalasi a mafakitale, kalasi ya chakudya ndi kalasi ya mankhwala malinga ndi momwe amagwiritsidwira ntchito.
Awiri, hydroxypropyl meth cellulose amagawidwa m'mitundu yowerengeka, yomwe kusiyana kwake ndi chiyani?
HPMC imatha kugawidwa mu mtundu wa nthawi yomweyo (SEGIC ") , palibe chisokonezo chenicheni. Za (kutsuka) kwa mphindi ziwiri, mamasukidwe amadzimadzi amawonjezeka pang'onopang'ono, ndikupanga cololous yowonekera bwino. Zogulitsa zotentha, m'madzi ozizira, zimatha kusulitsidwa mwachangu m'madzi otentha, monga kutentha mpaka kutentha kwazinthu), mpaka mapangidwe owoneka bwino Colloid.
Atatu, hydroxypropyl methy cellulose yankho mwanjira ili ndi chiyani?
1. Mitundu yonse ikhoza kuwonjezeredwa pazomwe mwa njira yosakanikirana;
2, ayenera kuwonjezeredwa mwachindunji ku yankho la kutentha kwabwinobwino, ndibwino kugwiritsa ntchito mtundu wobalalitsa madzi, mutatha kuwonjezera mu 10- 90 mphindi zokulitsidwa (zoyambitsa, zoyambitsa, zoyambitsa)
3. Mtundu wamba umasungidwa koyamba ndi madzi ophatikizika ndi madzi otentha, kenako kusungunuka powonjezera madzi ozizira pambuyo poyambitsa ndi kuzirala.
4. Ngati chovala ndi kukulunga ziphuphu zimachitika potha, ndi chifukwa kusakaniza sikokwanira kapena mtundu wamba umawonjezedwa mwachindunji kwa madzi ozizira. Pakadali pano, ziyenera kusunthidwa mwachangu.
5. Ngati thovu imapangidwa mukasungunuka, atha kusiyidwa kwa maola 2 mpaka 12 (nthawi) amathanso kuwonjezeredwa.
Zinayi, zophweka komanso zophweka kuti mudziwe za kumbali kapena kugwa kwa hydroxypropyl methy celluse?
1, kuyeretsa, kuyera ngakhale kuti sikutha kudziwa ngati HPMC ndiyabwino, ndipo ngati ikuwonjezeredwa mu zoyera zopangidwa ndi zoyera, koma, zinthu zabwino zonse zoyera ndizabwino.
2, Ubwino: Kuchita bwino kwa HPMC nthawi zambiri ma mesh ndi ma mesh, 120 zochepa, olimbikitsawo amangolankhula bwino.
3. Sitingafotokoze zabwino za keytary ndikwabwino kuposa kupanga ketulo, pali zinthu zambiri zomwe zimazindikira mtundu.
4, kuchuluka: kwakukulu pamlingo womwewo, wolemera kwambiri, kuposa wamkulu, nthawi zambiri chifukwa cha hydroxpyupyl ali pamwamba, ndiye kuti kusunga madzi ndikwabwino.
Zisanu, hydroxypropyl methl cellulose mu kuchuluka kwa ufa?
HPMC pofunsidwa kwenikweni kwa mlingo, mwa nyengo, kutentha, calcium phulusa labwino, putty ufa ufa wa mawonekedwe osiyanasiyana, ndipo pamakhala zosasiyana, ndipo kuyankhula, pakati pa 4-5 makilogalamu.
Isanu ndi chimodzi, hydroxypropyl me methyl cellulose akuwoneka bwino?
Khalani otopa ndi ufa wa Halder 100,000 Ok, kufunikira kwa matope ndi kutalika, koma, kugwiritsa ntchito madzi ndikofunikira kwambiri. Mu ufa wa putty, bola ngati kusungidwa kwamadzi ndikwabwino, mamasukidwe amatsika (7-8) , mafakisoni samakhudza kwambiri kusungidwa kwamadzi.
7, Kodi ndi zisonyezo zazikulu zaukadaulo za hydroxypyl noth celluse?
Hydroxypyl
Methyl zomwe zili
kukweza
phulusa
Kuchepetsa Kuchepetsa
Eyiti, ndi zinthu ziti zazikuluzikulu za hydroxypropyl methyl cellulose?
Zipangizo zamagetsi za HPMC: Kutayengeka kwa thonje, chloromethane, ma propylehane oxide, zopangira zina, mapiritsi a Alkali, acid toliene.
9, hydroxypropyll meth cellulose pogwiritsa ntchito ufa wa putety, kaya ndi mankhwala?
Mu ufa wa putty, imadya maudindo atatu: kukulitsa, kusungidwa kwamadzi ndikumanga. Kukula, cellose 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.
Hydroxypropyl methy cellulose sialic cellulose ether, ndiye kuti siayic?
Nthawi zambiri, zinthu zomwe sizimachita nawo ntchito zimachitika kawirikawiri.
CMC (Carboxymethyl cellulose) ndi ya cellulose yapa cellulose, motero amakumana ndi calcium itakhala star slag slark.
11. Kodi kutentha kwa gel nchinji kwa hydroxypypyl methylcelulose yokhudzana ndi?
Kutentha kwa gel kwa gelc kumakhudzana ndi methoxy zomwe zili. M'munsi methoxy zomwe zili, kutentha kwambiri kwa gel.
Khumi ndi awiri, putty ufa ufa ndi hydroxypropyl methl cellulose alibe chibwenzi?
Izi ndi zofunika !! HPMC siyisungidwa yamadzi osauka, idzayambitsa ufa.
13. Kodi pali kusiyana kotani pakati pa madzi ozizira yankho ndi kutentha yankho la hydroxypropyl pa celyl pakompyuta?
Mtundu wa HPMC Madzi osungunuka pambuyo pa chithandizo cha Glymoxal pamtunda, m'madzi ozizira amabalalika msanga, koma osasungunuka, kusinthidwa, kumathetsedwa. Mtundu wosungunuka wosungunuka sunali pamtunda wa Glyloxal. Kuchulukitsa kwa glyloxal ndi kwakukulu, kubalaku kumakhala kofulumira, koma ma viruyo amachedwa, voliyumu ndi yaying'ono, m'malo mwake.
14, hydroxypropyl methy cellulose engor ndi momwe mungabwezere udindo?
HPMC yopangidwa ndi njira yosungunulira imapangidwa ndi toluene ndipo isopropyl mowa ngati solvent. Ngati kusamba sikwabwino kwambiri, padzakhala kukoma kotsalira. (Kuchira kwa ASTRATIURE ndi njira yofunika kwambiri ya fungo)
15, Kugwiritsa ntchito mosiyana, momwe mungasankhire ma hydroxypropyl methyl cellulose?
Ufa wa putty: Zomwe zimasungidwa madzi ambiri, zomwe zimapangitsa kuti ntchito yomanga bwino ikhale (yolimbikitsidwa: 7010n)
Matope wamba a simenti: kusungidwa kwamadzi kwakukulu, kutentha kwambiri kukana, ma vidiyo amtundu umodzi (HPK100M)
Kugwiritsa ntchito guluu: Zogulitsa pompopompo, mafayilo apamwamba. (Zovomerezeka: HPK200MS)
Matope a gypsum: kusunthira kwamadzi kwakukulu, pakati komanso kuwoneka kochepa, ma vidio amtunduwu (olimbikitsidwa: hpk60000m)
16, hydroxypropyl methyl cellulose Kodi ndi chiyani?
HPMC kapena MHPC Alias hydroxpyl methy cellose, cellulose hydroxypropyl etheryl ether.
Kodi muli ndi zaka khumi ndi zisanu ndi ziwiri, hydroxypropyl methy cellulose pakugwiritsa ntchito ufa, putty ufa chifukwa chiyani?
Hpmc mu ufa wa putty, werengani maudindo atatu okukula, kusungidwa kwamadzi ndikumanga, chifukwa chotsalira:
1. Madzi ambiri amawonjezeredwa.
2. Pansi siyouma, pamwamba pa wosanjikiza wina wofuula, komanso wosavuta kuwira.
18, ma hydroxypropyl methl cellose ndi MC Kodi pali kusiyana kotani:
MC ndi methyllulose Nthawi zambiri, kuchuluka kwa kuloweza ndi 1.6-2.0, ndipo kusungunuka kwa madigiri osiyanasiyana ndikosiyananso, komwe kumakhala kwa ethersese ya ether.
. Mwambiri, ngati kuchuluka kwa kuwonjezera ndi kwakukulu, kukoma mtima ndikochepa ndipo ma virus ndi akulu, osunga madzi ndi okwera. Kuchuluka kwa kuwonjezera kumakhala kwakukulu pamadzi osunga madzi, ndipo mawonekedwewo sanagwirizane ndi kuchuluka kwa madzi. Kuthamanga kofala kumadalira kuchuluka kwa zosintha za cellulose komanso zabwino. Mu cellulose pamwamba pa ethell ethyl cellulose ndi hydroxypropyl methyl cellulose madzi osunga madzi ndi apamwamba.
. Kutentha kwa kutentha, kuti chiwonetsero chadziko lapansi chidzachitika.
. Ngati kutentha kwa madontho kumapitilira madigiri 40, kusungira kwamadzi kwa methyl cellulose kudzakhala koopsa kwambiri, kukhudza kwambiri kumakhudza matope.
(4) Methyl cellulose imachitika bwino kwambiri pantchito yomanga ndi kutsatira matope. Apa, zotsatsa zimatanthauzira mphamvu yomatira yomwe ikukhudzidwa pakati pa chida cha ogwira ntchito ndi khoma, ndiye kuti, kung'amba matope. Katundu womatira ndi waukulu, kukana kwa matope ndi waukulu, ndipo mphamvu yofunikira ndi ogwira ntchito poigwiritsa ntchito ndiyofunikanso, motero malo omanga matope ndi osauka.
