1. Mavuto omwe amapezeka mu putty powder
Kuyanika mwachangu kumachitika makamaka chifukwa cha kuchuluka kwa phulusa la ufa wa calcium wowonjezera (wochuluka kwambiri, kuchuluka kwa phulusa la ufa wa calcium womwe umagwiritsidwa ntchito mu putty formula ukhoza kuchepetsedwa moyenerera) umagwirizana ndi kuchuluka kwa kusungira madzi kwa ulusi, komanso kumagwirizana ndi kuuma kwa khoma.
Peeling ndi kupindika kumagwirizana ndi kuchuluka kwa madzi osungira madzi, zomwe zimakhala zosavuta kuchitika pamene kukhuthala kwa cellulose kuli kochepa kapena kuchuluka kwa kuwonjezera kumakhala kochepa.
Kuchotsa ufa wa mkati mwa khoma la putty ufa kumagwirizana ndi kuchuluka kwa phulusa la calcium ufa wowonjezera (kuchuluka kwa phulusa la phulusa la calcium mu putty formula ndi laling'ono kwambiri kapena chiyero cha phulusa la phulusa la calcium ndi chochepa kwambiri, ndi kuchuluka kwa phulusa. ufa wa calcium mu ufa wa putty uyenera kuwonjezeka moyenerera).Panthawi imodzimodziyo, zimagwirizananso ndi kuchuluka ndi ubwino wa cellulose, zomwe zimawonekera mu chiwerengero cha kusunga madzi kwa mankhwala.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.zidayambitsa.
Kutulutsa thovu kumakhudzana ndi chinyezi chowuma komanso kusanja kwa khoma, komanso kumakhudzana ndi zomangamanga.
Maonekedwe a ma pinpoints amagwirizana ndi cellulose, yomwe ili ndi mawonekedwe osapanga mafilimu.Nthawi yomweyo, zonyansa za cellulose zimachita pang'ono ndi phulusa la calcium.Ngati zomwe zimachitika kwambiri, ufa wa putty udzawoneka ngati zotsalira za nyemba.Sichikhoza kuikidwa pakhoma, ndipo ilibe mphamvu yogwirizana nthawi yomweyo.Kuphatikiza apo, izi zimachitikanso ndi zinthu monga carboxymethyl wothira mapadi.
Ma craters ndi ma pinholes amawonekera.Izi mwachiwonekere zikugwirizana ndi kuthamanga kwa madzi pamwamba pa hydroxypropyl methylcellulose yankho lamadzi.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?
Ma cellulose amagwiritsidwa ntchito ngati thickener komanso kusunga madzi mu putty.Chifukwa cha thixotropy ya cellulose yokha, kuwonjezera kwa cellulose mu ufa wa putty kumabweretsanso 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 cellulose komwe kumagwiritsidwa ntchito ndikokwera kwambiri.Opanga ena amagwiritsa ntchito cellulose 200,000 kupanga putty.Putty yomwe imapangidwa motere imakhala ndi kukhuthala kwakukulu, kotero imakhala yolemetsa pamene ikukanda.Kuchuluka kwa putty kumakoma amkati ndi 3-5 kg, ndipo mamasukidwe akayendedwe ndi 80,000-100,000.
4. Chifukwa chiyani ma viscosity cellulose amamva mosiyana m'nyengo yozizira ndi chilimwe?
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 cellulose, ndikusankha mankhwala omwe ali ndi kutentha kwa gel osakaniza.Yesani kugwiritsa ntchito methyl cellulose m'chilimwe.Kutentha kwa gel osakaniza kuli pakati pa Pafupifupi madigiri 55, ngati kutentha kuli kokwera pang'ono, kukhuthala kwake kudzakhudzidwa kwambiri.
