Hydroxyethyl Methyl Cellulose (MHEC)
Methyl Hydroxyethyl Cellulose (MHEC/HEMC)
CAS:9032-42-2
Hydroxyethyl Methyl Cellulose (HEMC) inonziwoMethyl Hydroxyethyl Cellulose(MHEC), ether ine cellulose inoshanda zvakasiyana-siyana, inoshanda zvakanyanya inoshandiswa semushonga wekuchengetedza mvura, stabilizer, adhesives uye firimu mumhando dzezvinhu zvekuvaka. MHEC/HEMC inoshandiswa zvakanyanya mumaindasitiri, akadai sekuvaka, sipo, pendi uye coating, tinogonawo kupa HEMC zvichienderana nezvinodiwa nevatengi. Mushure mekugadzirisa uye kugadzirisa pamusoro, tinogona kuwana zvinhu zvinopararira mumvura nekukurumidza, kuwedzera nguva yekuvhura, kudzivirira kudonha, nezvimwewo.

Maumbirwo emakemikari eMHEC
MHEC inogadzirwa nacellulose yechisikigo inosimbisa muvirinemapoka emethyl nehydroxyethylKugadziriswa uku kunovandudzakunyunguduka kwemvura, kusimba kwayo, uye kuenderana kwayonezvinhu zvakasiyana.
Hunhu Hukuru hweMHEC:
- Kunyungudika Kwemvura: Inonyungudika mumvura inopisa neinotonhora, zvichiita mhinduro dzakajeka.
- Kugona Kukora: Inopa viscosity yakakwira uye kutonga kwakanaka kwerheology.
- Kuchengetedza Mvura: Kunodzivirira kurasikirwa nemvura muzvigadzirwa zvakagadzirwa nesimende negypsum, zvichivandudza kugadzika uye kunamira.
- Zvisizvo Zvisiri zveIonic: Inoshanda nemakemikari akasiyana-siyana, kusanganisira munyu uye masurfactants.
- Kugona Kugadzira Mafirimu: Inogadzira mafirimu anochinjika uye anogara kwenguva refu, anobatsira pakuputira uye pakushandisa mishonga.
- Kugadzikana kwekupisa: Haipindi kupisa, zvichiita kuti ikwanise kushandiswa pakupisa kwakanyanya.

Mabhenefiti ekushandisa MHEC
✔ Kuchengeta Mvura Zvakanaka - Kunodzivirira kuoma nguva isati yakwana mukuvaka uye mukushandiswa kwekushongedza.
✔ Kunamira Kwakawedzerwa - Kunovandudza kusimba kwekubatanidza muma tile glues nema mortars.
✔ Yakagadzikana Munzvimbo Yakafara yepH - Inoshanda zvinobudirira munzvimbo dzine acidic, neutral, uye alkaline.
✔ Kuenderana kweNon-Ionic - Inoshanda zvakanaka nemunyu, ma surfactants, uye mamwe ma polymers.
✔ Inovandudza Rheology uye Mafambiro Emuviri - Inobvumira kupenya kwakadzora, kudzivirira kudonha nekudzika.
