Hydroxyethyl methyl cellulose

Hydroxyethyl methyl cellulose (HEMC) e hlophisitsoe ka ho hlahisa ethylene oxide e nkang methyl cellulose (MC). Mamello ea letsoai e ne e le betere ho feta ea polymer e sa fetoloang, 'me mocheso oa gel oa methyl hydroxyethyl cellulose o ne o phahame ho feta oa methyl cellulose.

Thepa

1. Ponahalo: Phofo e tšoeu kapa e tšoanang e tšoeu, ha ho na makasine ea mochini, e se nang monko ebile e se na tatso

2. Mocheso oa Gel (℃): 60-90

3. Litaba tsa metsi （Wt%）: ≤5.0

4. Litaba tsa Ash le （Wt%）: ≤5.0

5.HP: 5.0-8.0

6. Bolelele: ≥80 Mesh

7. Viscosity （mPa.s, tharollo ea metsi ea 2%, 20 ± 0.2 ℃）: 100000-20000

Ts'ebetso e kholo ea mahlale

1.Solubility: mofuta oa H ho HEMC o ka qhibiliha ka metsing a batang le metsing a chesang, ha mofuta oa L o ka qhibiliha ka metsing a batang feela, ha HEMC e sa qhibilihe ka har'a solvents tse ngata. Bokaholimo bo tšoeroeng ke HEMC bo hasane metsing a batang 'me ha bo kopane. Leha ho le joalo, e ka qhibiliha ka potlako ka ho fetola boleng ba eona ba pH ho 8-10

2. botsitso ba PH: boleng ba pH bo fapaneng ba phetoho ea viscosity ea 2-12 e nyane, ntle le hore phapang ena ea viscosity e fokotsehe

3. HEMC e na le litšobotsi tsa ho mpefatsa, ho emisa, ho qhalakanya, ho khomarela, ho emella, ho etsa filimi le ho boloka metsi, 'me matla a eona a ho boloka metsi a matla ho feta a methylcellulose. Ho tiea ha viscosis, ho hanyetsa hlobo le ho hasana ho betere ho feta hydroxyethyl cellulose

Ⅲ. Ts'ebeliso le tlhokomelo

HEMC e sebelisoa ka mokhoa o pharaletseng ho koaeleng ha latex ea metsi, thepa ea kaho le ea kaho, enke ea khatiso, ho cheka oli, jj

Ⅳ. Sephutheloana le polokelo

1.Be sehlahisoa sena se na le leqephe la datha la polokeho le polokelo ea polokeho ea polokeho

Sehlahisoa sena se tletse ka 25 lik'hilograma kraft pampiri le polasetiki filimi lined mokotla filimi

3.Sebenkele sebakeng se omileng, ela hloko bopaki ba mongobo
