Za hydroxypropyl methylcellulose pakugwiritsa ntchito putty powder

1. Mavuto omwe amapezeka mu putty powder

[Kuyanika mwachangu] Izi makamaka zimagwirizana ndi kuchuluka kwa phulusa la calcium ufa lomwe limawonjezeredwa (lalikulu kwambiri, limatha kuchepetsa bwino kuchuluka kwa phulusa la calcium lomwe limagwiritsidwa ntchito mu putty formula) komanso kuchuluka kwa madzi a hydroxypropyl methylcellulose (HPMC), ndipo ikugwirizananso ndi Zimagwirizana ndi kuuma kwa khoma.

[Kutsuka ndi kupindika] Izi zikugwirizana ndi kuchuluka kwa kusunga madzi.Hydroxypropyl methylcellulose (HPMC) imakhala ndi kukhuthala kocheperako ndipo imakonda kutere kapena kuchuluka kwake kumakhala kochepa.

[Kuchotsa ufa mkati mwa khoma la putty powder] Izi zikugwirizana ndi kuchuluka kwa phulusa la calcium ufa wowonjezeredwa (kuchuluka kwa phulusa la ufa wa calcium mu putty formula ndilochepa kwambiri kapena chiyero cha phulusa la phulusa la phulusa ndi lochepa kwambiri, ndi kuchuluka kwa phulusa. ufa wa calcium mu ufa wa putty ufa uyenera kuwonjezeka moyenerera) Panthawi imodzimodziyo, imakhalanso yokhudzana ndi kuchuluka kwa hydroxypropyl methylcellulose (HPMC), yomwe ikuwonetsedwa mu chiwerengero chosungira madzi cha mankhwala.Madzi osungira madzi ndi otsika, ndipo calcium oxide mu phulusa la ufa wa calcium sichimatengedwa mokwanira Calcium hydroxide conversion hydration) nthawi sikwanira, chifukwa.

[Matuza] Izi zikugwirizana ndi chinyezi chowuma ndi kusalala kwa khoma, komanso zimagwirizana ndi zomangamanga.

[Mapini akuwonekera] Izi zimagwirizana ndi mapadi, omwe alibe mphamvu zopanga filimu, komanso zonyansa za hydroxypropyl methylcellulose (HPMC) zimachita pang'ono ndi phulusa la calcium.Ngati kuchitako kuli koopsa, ufa wa putty udzawoneka tofu Slag state.Sichikhoza kuikidwa pakhoma, ndipo ilibe mphamvu yogwirizana nthawi yomweyo.Kuphatikiza apo, zinthu monga hydroxypropyl methylcellulose (HPMC) zosakanikirana ndi gulu la carboxymethyl zimawonekeranso panthawiyi.

[Mapanga ndi mapini a mapiri akuwoneka] Izi mwachiwonekere zikugwirizana ndi kuthamanga kwa madzi pamwamba pa hydroxypropyl methylcellulose (HPMC) yankho lamadzi.Kuvuta kwa madzi a hydroxyethyl aqueous solution sikuwonekeratu.Zingakhale bwino kuchita chithandizo chomaliza.

[The putty ndi yosavuta kusweka ndi kusanduka chikasu pambuyo kuyanika] Izi zikugwirizana ndi kuwonjezera kuchuluka kwa phulusa calcium ufa.Ngati kuchuluka kwa phulusa la phulusa la calcium likuwonjezeredwa kwambiri, kuuma kwa ufa wa putty kumawonjezeka mutatha kuyanika.Kuuma kokha popanda kusinthasintha kumang'amba mosavuta, makamaka Kumakhala kosavuta kusweka pamene kugwidwa 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 mankhwala, kukhuthala kwa putty ndi matope kumachepa pang'onopang'ono ndi kuwonjezeka kwa kutentha.Pamene kutentha kumaposa kutentha kwa gel osakaniza, mankhwalawa amachotsedwa m'madzi ndikutaya kukhuthala kwake.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.
