1. Putty ufa umauma msanga
Yankho: Izi makamaka zimagwirizana ndi kuwonjezera kwa phulusa la calcium ndi kuchuluka kwa madzi osungira madzi a fiber, komanso zokhudzana ndi kuuma kwa khoma.
2. The putty ufa peels ndi masikono
Yankho: Izi zikugwirizana ndi kuchuluka kwa madzi osungira madzi, zomwe zimakhala zosavuta kuchitika pamene kukhuthala kwa cellulose kuli kochepa kapena kuchuluka kwa kuwonjezera kumakhala kochepa.
3. Putty ufa wothira ufa
Yankho: Izi zikugwirizana ndi kuchuluka kwa phulusa la calcium lomwe lawonjezeredwa, ndipo limagwirizananso ndi kuchuluka ndi ubwino wa cellulose wowonjezeredwa. Zimawonetsedwa mu kuchuluka kwa kusungirako madzi kwa mankhwalawa. Mlingo wosungira madzi ndi wotsika ndipo nthawi ya hydration ya phulusa la calcium sikokwanira.
4. Putty ufa thovu
Yankho: Izi zikugwirizana ndi chinyezi chowuma ndi kuphwa kwa khoma, komanso zimagwirizana ndi zomangamanga.
5. Zizindikiro zimawonekera mu putty powder
Yankho: Izi zimagwirizana ndi ma cellulose, omwe ali ndi mawonekedwe osapanga mafilimu, komanso zonyansa za cellulose zimachita pang'ono ndi phulusa la calcium. Ngati zotsatira zake ndizovuta, ufa wa putty udzakhala ngati zotsalira za nyemba. Sichingakhoze kuikidwa pakhoma, ndipo ilibe mphamvu yogwirizana nthawi yomweyo. Kuphatikiza apo, izi zimachitikanso ndi zinthu monga magulu a carboxyl omwe amawonjezeredwa ku cellulose.
6. Mapanga ophulika ndi mapini amawonekera
Yankho: Izi mwachiwonekere zikugwirizana ndi kupsinjika kwamadzi pamwamba pa hydroxypropyl methylcellulose yankho lamadzi. Kuvuta kwa madzi a hydroxyethyl aqueous solution sikuwonekeratu. Zingakhale bwino kuchita chithandizo chomaliza.
7. Putty ikauma, zimakhala zosavuta kusweka ndi kutembenukira chikasu
Yankho: Izi zikugwirizana ndi kuwonjezera kuchuluka kwa calcium imvi. Ngati kuchuluka kwa calcium imvi kumawonjezeredwa kwambiri, kuuma kwa ufa wa putty kumawonjezeka mutatha kuyanika. Kuuma kokhako ndipo palibe kusinthasintha kumang'amba mosavuta, makamaka pamene akugonjetsedwa ndi mphamvu zakunja. Zimagwirizananso ndi kuchuluka kwa calcium oxide mu imvi calcium, yomwe idayambitsidwa kale.
8. Chifukwa chiyani ufa wa putty umakhala wochepa thupi ukathira madzi?
Yankho: 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.
9. N'chifukwa chiyani putty ndi yolemetsa kwambiri pakupukuta?
Yankho: 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 imamveka yolemetsa pamene ikukanda. Kuchuluka kovomerezeka kwa putty ufa wamakoma amkati ndi 3-5 kg, ndipo mamasukidwe akayendedwe ndi 80,000-100,000.
10. Chifukwa chiyani putty ndi matope opangidwa ndi cellulose okhala ndi mamasukidwe omwewo amamva mosiyana m'nyengo yozizira ndi chilimwe?
Yankho: Chifukwa cha kutentha kwa gelation kwa mankhwalawa, kukhuthala kwa mankhwalawa 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 tisankhe mankhwala okhala ndi kukhuthala kwapamwamba mukamagwiritsa ntchito mankhwalawa m'chilimwe, kapena kuonjezera kuchuluka kwa cellulose, ndikusankha chinthu chokhala ndi kutentha kwa gel osakaniza, yesetsani kugwiritsa ntchito mankhwala a MK, kutentha kwa gel osakaniza ndi pafupifupi. Pamwamba pa madigiri 70. Yesani kugwiritsa ntchito methyl cellulose m'chilimwe, kutentha kwake kwa gel kumakhala pafupifupi madigiri 55,
