Likarolo tsa Sehlahisoa:

1. Ponahalo: HEMC ke phofo e tšoeu kapa e batlang e le tšoeu; ha e na monko ebile ha e na tatso.

2. Ho qhibiliha: Mofuta oa H ho HEMC o ka qhibiliha ka metsing a ka tlase ho 60℃, 'me mofuta oa L o ka qhibiliha feela ka metsing a batang. HEMC e tšoana le HPMC 'me ha e qhibilihe ho li-solvent tse ngata tsa tlhaho. Kamora ho phekoloa holim'a metsi, HEMC e hasana ka metsing a batang ntle le ho kopana 'me ea qhibiliha butle, empa e ka qhibiliha kapele ka ho fetola boleng ba eona ba PH ho 8-10.

3. Boleng ba PH bo tsitsitseng: Viscosity ha e fetohe haholo ka har'a sebaka sa 2-12, 'me viscosity e fokotseha ka nģ'ane ho sebaka sena.

4. Botenya: sekgahla sa ho pasa sa letlooeng la 80 ke 100%; sekgahla sa ho pasa sa letlooeng la 100 ke ≥99.5%.

5. Matla a khoheli a fosahetseng: 0.27-0.60g/cm3.

6. Mocheso oa ho bola o kaholimo ho 200℃, 'me o qala ho cha ka 360℃.

7. HEMC e na le ho teteana ho hoholo, botsitso ba ho emisoa, ho qhalana, ho kopana, ho bopa habonolo, ho boloka metsi le litšobotsi tse ling.

8. Hobane sehlahisoa se na le sehlopha sa hydroxyethyl, mocheso oa gel oa sehlahisoa o fihla ho 60-90℃. Ho phaella moo, sehlopha sa hydroxyethyl se na le philicity e phahameng ea hydroxy, e leng se etsang hore sekhahla sa ho kopana ha sehlahisoa se be setle. Haholo-holo kahong ea mocheso o chesang le o phahameng lehlabula, HEMC e na le ho boloka metsi ho hoholo ho feta methyl cellulose ea viscosity e tšoanang, 'me sekhahla sa ho boloka metsi ha se ka tlase ho 85%.
