Ndeupi musiyano uripo pakati peCMC neMC?

CMC uye MC ese ari ese ma cellulose anobva kuseri ayo anowanzo shandiswa seanokora, mabhainda, uye anodzikamisa mune akasiyana maapplication, anosanganisira echikafu, emishonga, uye maindasitiri ekuchengeta munhu.Zvisinei, pane zvimwe zvakasiyana pakati pezviviri izvo zvakakosha kucherechedza.

CMC, kana Carboxymethyl Cellulose, i polymer inonyungudika nemvura inotorwa kubva muselulosi.Iyo inogadzirwa nekuita selulosi ine sodium chloroacetate uye kushandura mamwe emapoka ehydroxyl ari pa cellulose kuita mapoka ecarboxymethyl.CMC inoshandiswa zvakanyanya muzvigadzirwa zvechikafu, senge zvakabikwa, zvigadzirwa zvemukaka, uye sosi, pamwe chete muzvigadzirwa zvekuchengeta vanhu nemishonga.

MC, kana Methyl Cellulose, zvakare iri mvura-inonyungudika polima inotorwa kubva muselulosi.Iyo inogadzirwa nekuita serurosi ine methyl chloride uye kushandura mamwe emapoka ehydroxyl ari paselulosi kuita methyl ether mapoka.MC inoshandiswa seyakakora, binder, uye emulsifier mumashandisirwo akasiyana siyana, kusanganisira mune zvigadzirwa zvechikafu, senge sosi, madhirezi, uye madhiri akaomeswa nechando, uye mumishonga uye zvigadzirwa zvekuchengeta munhu.

Musiyano mumwe wakakosha pakati peCMC neMC hunhu hwavo hwekunyungudika.CMC inonyungudika zviri nyore mumvura kupfuura MC, uye inogona kuumba yakajeka, viscous mhinduro pane yakaderera concentrations.MC, kune rumwe rutivi, inoda kuwanda kwepamusoro uye / kana kupisa kuti inyunguduke zvizere mumvura, uye mhinduro dzayo dzinogona kuve dzakajeka kana kusviba.

Mumwe mutsauko maitiro avo mune akasiyana pH mamiriro.CMC yakanyanya kugadzikana mumamiriro ane acidic uye inokwanisa kushivirira yakafara pH siyana pane MC, iyo inogona kuputsa nekurasikirwa nekukora kwayo zvimiro munzvimbo dzine acidic.

Zvese zviri zviviri CMC uye MC zvinosiyana-siyana cellulose zvinobva kune zvakawanda zvinobatsira zvivakwa zvakasiyana siyana.Sarudzo yekuti ndeupi wekushandisa zvinoenderana nezvinodiwa zvechikumbiro uye hunhu hunodiwa hwekuita.
