Mphamvu ya Cellulose Ether mu Putty Powder Application

Chifukwa chiyani ufa wa putty uume mwachangu?

Izi makamaka zimagwirizana ndi kuwonjezera phulusa la calcium ndi kuchuluka kwa madzi osungira madzi a fiber, komanso zokhudzana ndi kuuma kwa khoma.

Nanga bwanji kusenda ndi kugudubuza?

Izi zikugwirizana ndi kuchuluka kwa kusungirako madzi, zomwe zimakhala zosavuta kuchitika pamene kukhuthala kwa cellulose kuli kochepa kapena kuchuluka kwa kuwonjezera kumakhala kochepa.

Kodi nthawi zina imakhala ndi zisonyezo?

Izi zimagwirizana ndi ma cellulose, omwe ali ndi mawonekedwe osapanga mafilimu, ndipo nthawi yomweyo, zonyansa za cellulose zimachita pang'ono ndi phulusa la calcium. Ngati zotsatira zake ndizovuta, 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.

Mapiri ophulika ndi mapini?

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.

Nchifukwa chiyani ufa wa putty umakhala wochepa thupi pambuyo powonjezera madzi?

Ma cellulose amagwiritsidwa ntchito ngati thickener komanso kusunga 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.

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 imakhala yolemetsa pamene ikukanda. Kuchuluka kwa putty kumakoma amkati ndi 3-5 kg, ndipo mamasukidwe akayendedwe ndi 80,000-100,000.

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 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 omwe ali ndi kutentha kwa gel osakaniza mukamagwiritsa ntchito mankhwala m'chilimwe. Kutentha kwa gel osakaniza kumakhala kopitilira madigiri 75. Wall putty national standard (JG/T298-2009) zofunikira, khalidwe lazinthu ndilokhazikika, zero voc ntchito zachilengedwe ndi zabwino. Nthawi zambiri, kutentha kwa gel wa methyl cellulose kumakhala pafupifupi madigiri 55 m'chilimwe. Ngati kutentha kuli kokwera pang'ono, kukhuthala kwake kudzakhudzidwa kwambiri.
