Hydroxyethyl Cellulose (HEC)
Hydroxyethyl cellulose(HEC)
CAS:9004-62-0
Hydroxyethyl cellulose(HEC) is nonionic water-soluble cellulose ether, inoshandiswa se thickener, inodzivirira colloid, mvura yekuchengetedza agent uye rheology modifier mumashandisirwo akasiyana-siyana semvura-based peints, zvivakwa zvekuvaka, mafuta emunda makemikari uye zvigadzirwa zvekutarisira zvemunhu.Nekuda kwezvimiro zvayo zvakasiyana, zvakadai sepamusoro viscosity, solubility mumvura inopisa uye inotonhora, uye kemikari inopedza mvura yakawanda, uye kemikari inoshandiswa mumagetsi anokosha HECred uye kugadzikana kwezvinhu zvakawanda.
HEC inogadzirwa nekuunza hydroxyethyl mapoka (-CH₂CH₂OH) mu cellulose polymer cheni kuburikidza ne etherification reaction. Iyi shanduko inovandudza kunyungudika kwayo kwemvura, kugona kukora, uye kuenderana nemagadzirirwo akasiyana.

Makiyi Zvakanakira:
1. Kuchengetedzwa Kwemvura Kwakanaka: Kunobatsira kudzivirira kuoma kusati kwasvika muzvigadzirwa zvesimenti-based uye zvizoro.
2. Yakagadzikana Pakati Pakawanda pH Range: Inoramba ichishanda mu acidic, neutral, uye alkaline nharaunda.
3. Non-Ionic uye Inopindirana: Inoshanda zvakanaka nemishonga yakasiyana-siyana, kusanganisira munyu, surfactants, uye mamwe mapolima.
4. Inosimudzira Kuitwa Kwechigadzirwa: Inovandudza ukobvu, kunamatira, kugadzira firimu, uye emulsification zvivakwa.
5. Yakabatana Nezvakatipoteredza uye Biodegradable: Yakatorwa kubva kune cellulose, HEC haina chepfu uye biodegradable.
6.Inovandudza Rheology uye Flow Properties: Inobvumira kudzora viscosity, kudzivirira kudonha, sagging, uye kupatsanurwa kwechikamu.
