1. Funso: Kodi maviscosity otsika, apakati-makamaka, ndi makulidwe apamwamba amasiyanitsidwa bwanji ndi kapangidwe kake, ndipo padzakhala kusiyana kotani?
Yankhani:
Zimamveka kuti kutalika kwa unyolo wa maselo ndi kosiyana, kapena kulemera kwa maselo ndi kosiyana, ndipo kumagawidwa kukhala otsika, apakati komanso apamwamba kwambiri. Zachidziwikire, mawonekedwe a macroscopic amafanana ndi kukhuthala kosiyana. ndende yemweyo ali osiyana mamasukidwe akayendedwe, mankhwala bata ndi asidi chiŵerengero. Ubale wachindunji makamaka umadalira yankho la mankhwala.
2. Funso: Ndi machitidwe otani azinthu zomwe zili ndi digiri ya kusintha pamwamba pa 1.15, kapena mwa kuyankhula kwina, kuchuluka kwa kulowetsedwa kwapamwamba, ntchito yeniyeni ya chinthucho yawonjezeredwa.
Yankhani:
Chogulitsacho chimakhala ndi kuchuluka kwa m'malo, kuchuluka kwamadzimadzi, ndikuchepetsa kwambiri pseudoplasticity. Zogulitsa zomwe zili ndi mamasukidwe omwewo zimakhala ndi digiri yayikulu yoloweza m'malo komanso zowoneka bwino zoterera. Zogulitsa zomwe zimaloŵa m'malo mwapamwamba zimakhala ndi yankho lonyezimira, pomwe zopangidwa zokhala ndi m'malo mwake zimakhala ndi yankho loyera.
3. Funso: Kodi ndikwabwino kusankha kukhuthala kwapakati pazakumwa zotupitsa zomanga thupi?
Yankhani:
Zapakatikati ndi otsika mamasukidwe akayendedwe mankhwala mlingo wa m'malo ndi za 0,90, ndi mankhwala ndi bwino asidi kukana.
4. Funso: Kodi cmc ingasungunuke bwanji mwachangu? Nthawi zina ndimagwiritsa ntchito, ndipo imasungunuka pang'onopang'ono itatha kuwira.
Yankhani:
Sakanizani ndi ma colloid ena, kapena mubalalitseni ndi 1000-1200 rpm agitator. Kufalikira kwa CMC sikwabwino, hydrophilicity ndiyabwino, ndipo ndiyosavuta kuphatikizira, ndipo zinthu zomwe zili ndi digiri yapamwamba yolowa m'malo ndizodziwikiratu! Madzi ofunda amasungunuka mofulumira kuposa madzi ozizira. Kuwira sikovomerezeka. Kuphika kwanthawi yayitali kwa zinthu za CMC kudzawononga mawonekedwe a maselo ndipo chinthucho chidzataya kukhuthala kwake!
