Hydroxyethyl Methyl Cellulose (MHEC)
Methyl Hydroxyethyl Cellulose(MHEC/HEMC)
CAS:9032-42-2
Hydroxyethyl Methyl Cellulose(HEMC) inonziwo seMethyl Hydroxyethyl Cellulose(MHEC), inosiyana-siyana, yakakwirira-inoshanda cellulose ether inoshandiswa seyepamusoro inoshanda yekuchengetedza mvura, stabilizer, adhesives uye firimu-forming agent mumhando dzezvivakwa zvekuvaka.MHEC/HEMC inoshandiswa zvakanyanya mumaindasitiri ekushandisa, sekuvaka, detergent, pendi uye kupfeka, isu tinogonawo kupa HEMC zvinoenderana nezvinodiwa nevatengi. Mushure mekugadziriswa uye kurapwa kwepamusoro, tinogona kuwana zvinhu zvakaparadzirwa mumvura nekukurumidza, kurebesa nguva yakavhurika, anti-sagging, nezvimwe.

Mushonga Wemakemikari weMHEC
MHEC inogadzirwa neetherifying natural cellulosepamwemethyl uye hydroxyethyl mapoka. Aya magadzirirwo anovandudza ayomvura solubility, viscosity, uye kugarisananezvinhu zvakasiyana.
Zvinhu Zvikuru zveMHEC:
- Mvura Solubility: Inonyungudika mumvura inopisa uye inotonhora, ichigadzira mhinduro dzakajeka.
- Kuwedzera Kugona: Inopa yakakwira viscosity uye yakanakisa rheology kutonga.
- Kuchengeta Mvura: Inodzivirira kurasikirwa kwemvura mune simende-yakavakirwa uye gypsum-yakavakirwa zvigadzirwa, kunatsiridza kurapa uye kunamatira.
- Non-Ionic Nature: Inopindirana nemhando dzakasiyana dzemakemikari, kusanganisira munyu uye surfactants.
- Firimu-Kuumba Mano: Inogadzira anochinjika uye anogara kwenguva refu mafirimu, anobatsira mumajasi uye nemishonga yekushandisa.
- Thermal Stability: Inopesana nekupisa, zvichiita kuti ive yakakodzera kushandiswa kwepamusoro-tembiricha.

Zvakanakira Kushandisa MHEC
✔ Yakanakisa Kuchengeta Mvura - Inodzivirira kuoma nguva isati yakwana mukuvaka uye cosmetic application.
✔ Enhanced Adhesion - Inovandudza kusimba kwekubatanidza mumatairi anonamira uye dhaka.
✔ Yakagadzikana Mukati meWide pH Range - Inoshanda zvinobudirira munzvimbo dzine acidic, dzisina kwazvakarerekera, uye alkaline.
✔ Non-Ionic Compatibility - Inoshanda zvakanaka nemunyu, ma surfactants, uye mamwe mapolymer.
✔ Inovandudza Rheology uye Kuyerera Zvivakwa - Inobvumira inodzorwa viscosity, kudzivirira kudonha nekudonha.
