Ponena za hydroxypropyl methylcellulose pogwiritsira ntchito putty powder

1. Mavuto omwe amapezeka mu putty powder

youma mofulumira

Izi makamaka zimagwirizana ndi kuchuluka kwa phulusa la phulusa la calcium lowonjezera (lalikulu kwambiri, kuchuluka kwa phulusa la phulusa la calcium lomwe limagwiritsidwa ntchito mu putty formula likhoza kuchepetsedwa moyenera) komanso kuchuluka kwa madzi a hydroxypropyl methylcellulose (HPMC), komanso kumagwirizana ndi kuuma kwa khoma kumakhudzana.

Peeling ndi kugudubuza

Izi zikugwirizana ndi kuchuluka kwa kusungirako madzi, zomwe zimakhala zosavuta kuchitika pamene viscosity ya hydroxypropyl methylcellulose (HPMC) ili yochepa kapena ndalama zomwe zimawonjezeredwa ndizochepa.

De-ufa wa mkati khoma putty ufa

Izi zimagwirizana ndi kuchuluka kwa ufa wa phulusa la calcium (kuchuluka kwa phulusa la phulusa la ufa mu putty formula ndi lochepa kwambiri kapena chiyero cha phulusa la phulusa la phulusa ndi lochepa kwambiri, ndipo kuchuluka kwa phulusa la phulusa la ufa wa phulusa mu ufa wa putty uyenera kukhala kuchuluka koyenera), komanso kumagwirizana ndi kuchuluka kwa hydroxypropyl methyl Kuchuluka kwa cellulose (HPMC) kumakhudzana ndi mtundu wake, womwe umawonetsedwa pakusunga madzi kwa mankhwalawa.Madzi osungira madzi ndi otsika, ndipo nthawi ya phulusa la ufa wa calcium (calcium oxide mu phulusa la ufa wa calcium sichimatembenuzidwa mokwanira kukhala calcium hydroxide) sikokwanira., chifukwa.

kubwebweta

Izi zikugwirizana ndi chinyezi chowuma ndi kuphwanyidwa kwa khoma, komanso zimagwirizana ndi zomangamanga.

pin point

Izi zimagwirizana ndi cellulose, yomwe ili ndi mawonekedwe osapanga mafilimu.Nthawi yomweyo, zonyansa za hydroxypropyl methylcellulose (HPMC) zimachita pang'ono ndi phulusa la calcium.Ngati zotsatira zake ndizovuta, ufa wa putty udzakhala ngati zotsalira za nyemba.Sichikhoza kuikidwa pakhoma, ndipo ilibe mphamvu yogwirizana nthawi yomweyo.Kuphatikiza apo, zinthu monga hydroxypropyl methylcellulose (HPMC) zosakanikirana ndi gulu la carboxymethyl zimawonekeranso panthawiyi.

Mapiri ndi mapiniwo amawonekera

Izi mwachiwonekere zikugwirizana ndi kuthamanga kwa madzi pamwamba pa hydroxypropyl methylcellulose (HPMC) yankho lamadzimadzi.Kuvuta kwa madzi a hydroxyethyl aqueous solution sikuwonekeratu.Zingakhale bwino kuchita chithandizo chomaliza.

Putty ikauma, imakhala yosavuta kusweka ndikusintha chikasu

Izi zikugwirizana ndi kuwonjezera kwa ufa wambiri wa phulusa-calcium.Ngati kuchuluka kwa phulusa-calcium ufa kuwonjezeredwa kwambiri, kuuma kwa ufa wa putty kumawonjezeka mutatha kuyanika.Ngati ufa wa putty ulibe kusinthasintha, umasweka mosavuta, makamaka pamene umakhala ndi mphamvu yakunja.Zimagwirizananso ndi kuchuluka kwa calcium oxide mu phulusa la ufa wa calcium.

2. Chifukwa chiyani ufa wa putty umakhala wochepa thupi ukathira madzi?

Hydroxypropyl methylcellulose (HPMC) amagwiritsidwa ntchito ngati thickener komanso kusunga madzi mumafuta.Chifukwa cha thixotropy wa hydroxypropyl methylcellulose (HPMC), hydroxypropyl methylcellulose mu putty powder Kuwonjezera kwa HPMC kunayambitsanso thixotropy pambuyo powonjezera madzi ku putty.thixotropy uyu amayamba chifukwa cha kuwonongedwa kwa mwachisawawa ophatikizana dongosolo la zigawo zikuluzikulu mu putty ufa.Kapangidwe kameneka kamakhala kakupumula ndipo kumasweka ndi kupsinjika maganizo.Ndiko kuti, mamasukidwe akayendedwe amachepetsa pansi kusonkhezera, ndi mamasukidwe akayendedwe akuchira pamene ayimirira.

3. Nchifukwa chiyani putty imakhala yolemetsa kwambiri pakupukuta?

Pamenepa, kukhuthala kwa hydroxypropyl methylcellulose (HPMC) komwe amagwiritsidwa ntchito nthawi zambiri kumakhala kokwera kwambiri, ndipo opanga ena amagwiritsa ntchito 200,000 yuan kupanga putty.Putty yomwe imapangidwa motere imakhala ndi kukhuthala kwakukulu, kotero imamira pamene mtanda ukukula.kumva kwa.Kuchuluka kwa putty kumakoma amkati ndi 3-5 kg, ndipo mamasukidwe akayendedwe ndi 80,000-100,000.

4. Nchifukwa chiyani mukuwona kuti kukhuthala kwa hydroxypropyl methylcellulose (HPMC) yokhala ndi mamasukidwe omwewo ndi osiyana m'nyengo yozizira ndi yotentha?

Chifukwa cha kutentha kwa zinthuzo, kukhuthala kwa putty ndi matope kumachepa pang'onopang'ono ndi kuwonjezeka kwa kutentha.Pamene kutentha kumaposa kutentha kwa gel osakaniza mankhwala, mankhwala adzakhala precipitated kuchokera madzi ndi kutaya mamasukidwe akayendedwe ake.Kutentha kwa chipinda m'chilimwe nthawi zambiri kumakhala pamwamba pa madigiri 30, komwe kumakhala kosiyana kwambiri ndi kutentha m'nyengo yozizira, kotero kukhuthala kumakhala kotsika.Ndibwino kuti musankhe mankhwala okhala ndi viscosity yapamwamba mukamagwiritsa ntchito mankhwalawa m'chilimwe, kapena kuwonjezera kuchuluka kwa hydroxypropyl methylcellulose (HPMC), ndikusankha mankhwala omwe ali ndi kutentha kwa gel osakaniza.
