Mavuto omwe amapezeka mu putty powder

Vuto lodziwika bwino mu ufa wa putty ndikuti amawuma mwachangu. Izi makamaka chifukwa cha kuchuluka kwa calcium phulusa ufa wowonjezeredwa (ochuluka kwambiri, kuchuluka kwa calcium calcium ufa wogwiritsidwa ntchito mu putty formula akhoza kuchepetsedwa moyenerera, zomwe zimagwirizana ndi kuchuluka kwa madzi osungira madzi a fiber, komanso kuuma kwa khoma; kupukuta ndi kupukuta Izi zikugwirizana ndi kusungidwa kwa madzi Kutsika kwa ma cellulose kumakhala kovuta kwambiri kapena kuwonjezereka kwapang'onopang'ono kwa khoma la mkati ufa (kuchuluka kwa phulusa la phulusa la calcium mu putty formula ndi laling'ono kwambiri kapena chiyero cha phulusa la ufa wa calcium Ngati ndi wochepa kwambiri, umagwirizana ndi kuchuluka kwa phulusa la phulusa la phulusa mu ufa wa putty, ndipo ndi zimagwirizananso ndi kuchuluka ndi ubwino wa cellulose, zomwe zikuwonetsedwa mu mlingo wosungira madzi wa mankhwala The calcium oxide mu calcium hydroxide sichimatembenuzidwa mokwanira ku calcium hydroxide, yomwe imayamba chifukwa cha nthawi yokwanira ya hydration; kuchita thovu. Izi zimagwirizana ndi chinyezi chowuma ndi kutsetsereka kwa khoma, komanso zimagwirizana ndi zomangamanga; zizindikiro zimawonekera. Izi zimagwirizana ndi Ma cellulose, katundu wake wopanga mafilimu ndi osauka, ndipo zonyansa za cellulose zimachita pang'ono ndi phulusa la calcium. Ngati zotsatira zake ndizovuta, ufa wa putty udzakhala mu boma. Sichikhoza kuikidwa pakhoma, ndipo ilibe mphamvu yogwirizana. Kuphatikiza apo, ulusi Izi zimachitikanso muzinthu zomwe zasakanizidwa ndi magulu a carboxymethyl mu element; mapiri ndi moto zimawonekera. Izi mwachiwonekere zikugwirizana ndi kuthamanga kwa madzi pamwamba pa hydroxypropyl methylcellulose yankho lamadzi. Kuchulukana kwamadzi pamadzi amadzimadzi a hydroxyethyl sikuwonekera. Kumaliza mankhwala kudzakhala kwabwino; putty ndi yosavuta kusweka ndi kutembenukira chikasu pambuyo kuyanika. Izi zikugwirizana ndi kuwonjezeredwa kwa ufa wambiri wa phulusa la calcium. Ngati kuchuluka kwa phulusa la phulusa la calcium ndi lochuluka, kuuma kwa ufa wa putty kumawonjezeka pambuyo poyanika. Kuuma kokhako sikophweka N'kosavuta kusweka pamene kusinthasintha, makamaka pamene akugonjetsedwa ndi mphamvu zakunja. Zimagwirizananso ndi kuchuluka kwa calcium oxide mu phulusa la ufa wa calcium.

Coarse fineness sikungowononga, komanso kumachepetsa mphamvu ya m'deralo ya matope. Pamene matope owuma owuma amangidwa m'dera lalikulu, kuthamanga kwa machiritso a dothi la ufa wouma kumachepetsedwa kwambiri, ndipo ming'alu idzawoneka chifukwa cha nthawi zosiyanasiyana zochiritsira. Kwa matope opopera omwe amapangidwa ndi makina, kufunikira kwa fineness ndipamwamba chifukwa cha nthawi yochepa yosakaniza. Ubwino wa cellulose umakhudzanso kusungidwa kwa madzi. Nthawi zambiri, ma etha a methyl cellulose okhala ndi kukhuthala kofanana koma fineness yosiyana, ngati awonjezera kuchuluka komweko, kuwongolera bwino kumapangitsa kuti madzi asungidwe bwino.
