youma mofulumira
Izi makamaka chifukwa cha kuwonjezereka kwa phulusa la phulusa la phulusa (kuchuluka kwa phulusa la phulusa la calcium lomwe limagwiritsidwa ntchito mu putty formula likhoza kuchepetsedwa moyenera) likugwirizana ndi kuchuluka kwa madzi osungiramo madzi a hydroxypropyl methylcellulose, komanso kumagwirizana ndi kuuma kwa khoma. .
Peeling ndi kugudubuza
Izi zimagwirizana ndi kuchuluka kwa phulusa la calcium kapena kuchepa kwa madzi otsika a hydroxypropyl methylcellulose, omwe amathanso kuchitika pamene ma viscosity a cellulose ali otsika kapena kuchuluka kwake kuli kochepa.
De-ufa wa mkati khoma putty ufa
Izi zikugwirizana ndi kuchuluka kwa phulusa la ufa wa calcium wowonjezera (kuchuluka kwa phulusa la phulusa la phulusa mu ndondomeko ya putty ndilochepa kwambiri kapena chiyero cha ufa wa phulusa la calcium ndi chochepa kwambiri, ndipo kuchuluka kwa phulusa la phulusa la phulusa mu ufa wa putty uyenera ziwonjezeke moyenerera), komanso zimagwirizananso ndi kuwonjezeredwa kwa cellulose Pali mgwirizano pakati pa kuchuluka ndi mtundu, zomwe zimawonetsedwa pakusunga madzi kwa mankhwalawa. Madzi osungira madzi ndi otsika, ndipo nthawi yochitira phulusa la calcium powder (calcium oxide mu phulusa la ufa wa calcium sichimatembenuzidwa mokwanira kukhala calcium hydroxide) sichikwanira, chomwe chimayambitsa.
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 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 wosakanizidwa ndi cellulose.
Ziphuphu ndi mapibowo 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. Zimakhudzananso ndi kuwonjezereka kwakukulu kwa hydroxypropyl methylcellulose.
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.
Nchifukwa chiyani ufa wa putty umakhala wochepa thupi pambuyo powonjezera madzi?
Ma cellulose amagwiritsidwa ntchito ngati thickener komanso kusunga madzi pa putty. Chifukwa cha thixotropy ya cellulose yokha, kuwonjezera kwa cellulose mu putty powder 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 kamasweka ndi kupsinjika maganizo. Ndiko kuti, mamasukidwe akayendedwe amachepetsa pansi kusonkhezera, ndi mamasukidwe akayendedwe akuchira pamene ayimirira.
N'chifukwa chiyani putty imakhala yolemetsa kwambiri pakupukuta?
Pamenepa, kukhuthala kwa cellulose komwe kumagwiritsidwa ntchito nthawi zambiri ndikokwera kwambiri. Opanga ena amagwiritsa ntchito cellulose 200,000 kupanga putty. Putty yomwe imapangidwa motere imakhala ndi kukhuthala kwakukulu, kotero imamveka yolemetsa pamene ikukanda. Kuchuluka kwa putty kumakoma amkati ndi 3-5 kg, ndipo mamasukidwe akayendedwe ndi 80,000-100,000.
Nchifukwa chiyani kukhuthala kwa cellulose kumamveka mosiyana mukamagwiritsa ntchito cellulose ya viscosity yomweyi 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.
