Zotsatira za MC fineness pamatope

The MC ntchito youma ufa matope chofunika kukhala ufa, ndi okhutira madzi otsika, ndi fineness amafunanso 20% ~ 60% ya tinthu kukula kukhala zosakwana 63um.Ubwino wake umakhudza kusungunuka kwa methyl cellulose ether.Coarse MC nthawi zambiri imakhala ngati ma granules, ndipo ndiyosavuta kusungunuka m'madzi popanda kuphatikizika, koma kusungunuka kumakhala pang'onopang'ono, kotero sikoyenera kugwiritsidwa ntchito mumatope owuma a ufa.

Mumatope owuma a ufa, MC imamwazikana pakati pa zophatikizira, zodzaza bwino ndi simenti ndi zida zina zomangira.Ufa wokwanira wokwanira ungapewe methyl cellulose ether agglomeration mukasakaniza ndi madzi.Pamene MC imawonjezeredwa ndi madzi kuti asungunuke ma agglomerates, zimakhala zovuta kwambiri kumwazikana ndi kupasuka.Coarse MC singowononga, komanso imachepetsa mphamvu ya m'deralo ya matope.Pamene matope owuma owuma akugwiritsidwa ntchito m'dera lalikulu, kuthamanga kwa machiritso a matope owuma a m'deralo kudzachepetsedwa kwambiri, ndipo ming'alu idzawoneka chifukwa cha nthawi zosiyanasiyana zochiritsira.Kwa makina opopera matope opangidwa ndi makina, chifukwa cha nthawi yochepa yosakaniza, kufunikira kwa fineness ndipamwamba.

Ubwino wa MC umakhudzanso kusunga kwake madzi.Nthawi zambiri, ma etha a methyl cellulose okhala ndi kukhuthala kofanana koma fineness yosiyana, pansi pa kuchuluka komweko, kuwongolera bwino kumapangitsa kuti madzi asungidwe bwino.

Kusungidwa kwa madzi kwa MC kumagwirizananso ndi kutentha komwe kumagwiritsidwa ntchito, ndipo kusungirako madzi kwa methyl cellulose ether kumachepa ndi kuwonjezeka kwa kutentha.Ntchito yotentha magawo pansi pa kutentha zinthu imathandizira machiritso a simenti ndi kuumitsa youma ufa mtondo.Kutsika kwa kuchuluka kwa kusunga madzi kumabweretsa chikoka cha kugwira ntchito ndi kukana kwa ming'alu, ndipo kumakhala kofunika kwambiri kuti muchepetse chikoka cha kutentha pansi pa chikhalidwe ichi.

Ngakhale kuti zowonjezera za methyl hydroxyethyl cellulose ether panopa zimaonedwa kuti ndizo patsogolo pa chitukuko cha zamakono, kudalira kwawo kutentha kudzapitirizabe kufooketsa ntchito ya ufa wouma.Kupyolera mu chithandizo chapadera pa MC, monga kuonjezera mlingo wa etherification, ndi zina zotero, zotsatira zosungira madzi zimatha kusungidwa pa kutentha kwakukulu, kotero kuti zitha kupereka ntchito yabwino pansi pa zovuta.
