Mayankho a mafunso okhudza kugwiritsa ntchito CMC

1. Funso: Kodi kukhuthala kochepa, kukhuthala kwapakati, ndi kukhuthala kwakukulu kumasiyanitsidwa bwanji ndi kapangidwe kake, ndipo kodi padzakhala kusiyana kulikonse pakukhazikika?

Yankho:

Zimamveka kuti kutalika kwa unyolo wa mamolekyulu ndi kosiyana, kapena kulemera kwa mamolekyulu ndi kosiyana, ndipo kumagawidwa m'magulu otsika, apakati ndi apamwamba. Zachidziwikire, magwiridwe antchito a macroscopic amagwirizana ndi kukhuthala kosiyana. Kuchuluka komweko kuli ndi kukhuthala kosiyana, kukhazikika kwa chinthu ndi chiŵerengero cha asidi. Ubale wolunjika makamaka umadalira yankho la chinthucho.

2. Funso: Kodi magwiridwe antchito enieni a zinthu zomwe zili ndi digiri ya kusintha pamwamba pa 1.15 ndi ati, kapena mwa kuyankhula kwina, kuchuluka kwa kusintha komwe kumachitika, magwiridwe antchito enieni a chinthucho amawonjezeka.

Yankho:

Chogulitsachi chili ndi mlingo waukulu wosinthira, kuchuluka kwa madzi, komanso kuchepa kwa pseudoplasticity. Zogulitsa zomwe zili ndi kukhuthala komweko zimakhala ndi mlingo waukulu wosinthira komanso kumverera kotsetsereka koonekeratu. Zogulitsa zomwe zili ndi mlingo waukulu wosinthira zimakhala ndi yankho lowala, pomwe zogulitsa zomwe zili ndi mlingo waukulu wosinthira zimakhala ndi yankho loyera.

3. Funso: Kodi n'koyenera kusankha kukhuthala kwapakati pa zakumwa zowiritsa mapuloteni?

Yankho:

Zinthu zokhuthala zapakati ndi zochepa, mulingo wosinthira ndi pafupifupi 0.90, ndipo zinthuzo zimakhala ndi kukana bwino kwa asidi.

4. Funso: Kodi CMC ingasungunuke bwanji mwachangu? Nthawi zina ndimagwiritsa ntchito, ndipo imasungunuka pang'onopang'ono ikawiritsa.

Yankho:

Sakanizani ndi ma colloid ena, kapena falitsani ndi agitator ya 1000-1200 rpm. Kufalikira kwa CMC sikwabwino, hydrophilicity ndi yabwino, ndipo n'kosavuta kusonkhanitsa, ndipo zinthu zomwe zili ndi digiri yapamwamba yosinthira zimakhala zoonekeratu! Madzi ofunda amasungunuka mwachangu kuposa madzi ozizira. Kuwiritsa nthawi zambiri sikuvomerezeka. Kuphika kwa nthawi yayitali kwa zinthu za CMC kudzawononga kapangidwe ka molekyulu ndipo chinthucho chidzataya kukhuthala kwake!
