Methyl cellulose ether

1.Zinthu:

(1). Kusunga madzi: KuyambiraMethyl cellulose etherMankhwala amatha kuyamwa madzi ambiri, amatha kusunga madzi mumatope ndi gypsum.

(2). Kusungirako mawonekedwe: yankho lake lamadzi lili ndi ma viscoelastic apadera, omwe amatha kukhalabe ndi mawonekedwe a zinthu za ceramic.

(3). Lubricity: MC imatha kuchepetsa mikangano ndikuwongolera magwiridwe antchito a ceramic ndi konkriti.

(4). Kukhazikika kwa PH: kukhuthala kwa njira yamadzimadzi sikukhudzidwa ndi asidi kapena zamchere. Njira yake yamadzimadzi imakhalabe yokhazikika pamitundu yambiri ya pH, nthawi zambiri pakati pa 3.0 ndi 11.0.

(5). Mafilimu opanga mafilimu: MC imatha kupanga filimu yolimba, yosinthika komanso yowonekera bwino yokhala ndi mafuta abwino.

2. Fomula ya mamolekyulu:

N: digiri ya polymerization;R: -H, -CH3 kapena CH2CHOHCH3

3.Physical and Chemical Properties

Njira yothetsera:

Choyamba kutentha madzi ku 80-90 ° C, pang'onopang'ono kuwonjezera MC pansi pa kusonkhezera kosalekeza, dikirani kuti kutentha kugwere, kenako kuziziritsa kupanga yunifolomu yankho lamadzimadzi. Kapena onjezerani gawo limodzi mwa magawo atatu pa magawo awiri mwa magawo atatu a madzi ofunikira poyamba, kutentha kwa 80-90 ° C, pang'onopang'ono kuwonjezera MC pansi pa kusonkhezera kosalekeza, mutatha kukulitsa, yikani madzi ozizira otsalawo, ndikuziziritsa.
