Mavuto odziwika a putty osagwira madzi pamakoma amkati

1. Mavuto omwe amapezeka mu putty powder:

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

1.2 Peeling ndi kupindika. Izi zimagwirizana ndi kuchuluka kwa kusungirako madzi, zomwe zimakhala zosavuta kuchitika pamene kukhuthala kwa cellulose kuli kochepa kapena kuchuluka kwa kuwonjezereka kuli kochepa.

1.3 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.

1.4 Kuthamanga kwa magazi. Izi zikugwirizana ndi chinyezi chowuma ndi kuphwanyidwa kwa khoma, komanso zimagwirizana ndi zomangamanga.

1.5 Pin point ikuwoneka. 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.

1.6 Mapiri amapiri ndi mapini 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.

1.7 Putty ikauma, zimakhala zosavuta kusweka ndikusintha 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 kungasokoneze mosavuta, makamaka pamene akugonjetsedwa ndi mphamvu zakunja. Zimagwirizananso ndi kuchuluka kwa calcium oxide mu imvi calcium, yomwe idayambitsidwa kale.

2. Chifukwa chiyani ufa wa putty umakhala wochepa thupi ukathira madzi?

Ma cellulose amagwiritsidwa ntchito ngati thickener komanso kusunga madzi mu putty. Chifukwa cha thixotropy ya cellulose yokha, kuwonjezera kwa cellulose mu ufa wa putty kumabweretsanso thixotropy atatha kuwonjezera madzi ku putty. thixotropy uyu amayamba chifukwa cha kuwonongedwa kwa mwachisawawa ophatikizana dongosolo la zigawo zikuluzikulu mu putty ufa. Kapangidwe kameneka kamakhala kakupumula ndipo kumasweka ndi kupsinjika maganizo. Ndiko kuti, mamasukidwe akayendedwe amachepetsa pansi kusonkhezera, ndi mamasukidwe akayendedwe akuchira pamene ayimirira.

3. N'chifukwa chiyani putty ndi yolemetsa kwambiri pakupukuta?

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

4. Chifukwa chiyani putty ndi matope opangidwa ndi cellulose okhala ndi mamasukidwe omwewo amamveka 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 m'chilimwe, kapena kuwonjezera kuchuluka kwa cellulose, ndikusankha mankhwala omwe ali ndi kutentha kwa gel osakaniza. Yesani kusankha mankhwala omwe ali ndi kutentha kwa gel pamwamba pa madigiri 70. Yesetsani kuti musagwiritse ntchito methyl cellulose m'chilimwe, kutentha kwake kwa gel kumakhala pafupifupi madigiri 55, ngati kutentha kuli kokwera pang'ono, kukhuthala kwake kudzakhudzidwa kwambiri.
