Tikamagwiritsa ntchito putty powder, nthawi zambiri padzakhala mavuto, kotero sitidziwa chifukwa chake.Ndikuganiza kuti payenera kukhala mitundu isanu ndi iwiri yamavuto omwe nthawi zambiri amawonekera mu putty powder!
Choyamba: Chitani mofulumira.Izi makamaka zimagwirizana ndi kuwonjezera phulusa la calcium ndi kuchuluka kwa madzi osungira madzi a fiber, komanso zokhudzana ndi kuuma kwa khoma.
Awiri: peel ndi roll.Izi zikugwirizana ndi kuchuluka kwa kusungirako madzi, zomwe zimakhala zosavuta kuchitika pamene kukhuthala kwa cellulose kuli kochepa kapena kuchuluka kwa kuwonjezera kumakhala kochepa.
Chachitatu: kuchotsa ufa.Izi zimagwirizana 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.
Chachinayi: Matuzu.Izi zikugwirizana ndi chinyezi chowuma ndi kuphwanyidwa kwa khoma, komanso zimagwirizana ndi zomangamanga.
Chachisanu: Pawonekera nsonga.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 magulu a carboxyl omwe amawonjezeredwa ku cellulose.
Chachisanu ndi chimodzi: Mapanga ophulika ndi mabowo ang'onoang'ono amawonekera.Izi mwachiwonekere zikugwirizana ndi kuthamanga kwamadzi pamwamba pa hydroxypropyl methylcellulose yankho lamadzimadzi, koma kukangana kwa madzi pamwamba pa hydroxyethyl yankho lamadzimadzi sikuwonekera.Zidzakhala bwino kuchita chithandizo chopepuka.
Zisanu ndi ziwiri: Putty ikauma, imakhala yosavuta kusweka ndi kutembenukira chikasu.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 grey calcium.
1. Chifukwa chiyani ufa wa putty umakhala wochepa thupi ukathira madzi?
Cellulose ether imagwiritsidwa ntchito ngati chowonjezera komanso chosungira madzi mu 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.
2. Nchifukwa chiyani putty imakhala yolemetsa kwambiri pakupukuta?
Pankhaniyi, 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 kwa putty kumakoma amkati ndi 3-5 kg, ndipo mamasukidwe akayendedwe ndi 80,000-100,000.
3. Chifukwa chiyani putty ndi matope opangidwa ndi cellulose okhala ndi mamasukidwe omwewo amamva mosiyana m'nyengo yozizira ndi chilimwe?
Chifukwa cha kutentha kwa gelation ya 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 musankhe mankhwala okhala ndi viscosity yapamwamba mukamagwiritsa ntchito mankhwalawa m'chilimwe, kapena kuwonjezera kuchuluka kwa cellulose, ndikusankha chinthu chokhala ndi kutentha kwa gel okwera.
