Cellulose, hydroxyethyl ether (MW 1000000)

Hydroxyethyl cellulose(HEC) i polymer inonyungudika nemvura inotorwa kubva muselulosi kuburikidza nekuunzwa kwemapoka ehydroxyethyl. Huremu hwemamorekuru (MW) hwakatsanangurwa, 1000000, inomiririra yakakwira molecular uremu musiyano. Heino tarisiro yehydroxyethyl cellulose ine huremu hwemamorekuru hwe1000000:

Hydroxyethyl Cellulose (HEC):

1. Chemical Structure:
   • HEC inogadzirwa neselulosi uko mapoka ehydroxyethyl akasungirirwa kune anhydroglucose mayunitsi echeni ye cellulose. Kugadziridzwa uku kunowedzera kunyungudika kwemvura uye zvimwe zvinoshanda zve cellulose.
2. Molecular Weight:
   • Huremu hwataurwa hwe1000000 hunoratidza uremu hwemhando yepamusoro. Huremu hwemamorekuru hunokanganisa viscosity, rheological properties, uye kushanda kweHEC mumashandisirwo akasiyana-siyana.
3. Muviri Fomu:
   • Hydroxyethyl cellulose ine huremu hwemamorekuru hwe1000000 inowanikwa muchimiro chemuchena kusvika kuchena, hupfu husina hwema. Inogonawo kupihwa semushonga wemvura kana kupararira.
4. Kunyungudika kwemvura:
   • HEC inonyungudika nemvura uye inogona kuumba mhinduro dzakajeka uye dzakajeka mumvura. Iyo dhigirii yekunyungudika uye viscosity inogona kukanganiswa nezvinhu zvakaita setembiricha, pH, uye kutarisisa.
5. Applications:
   • Thickening Agent: HEC inowanzoshandiswa seyakakora mumiriri mune akasiyana maapplication, anosanganisira pendi, machira, anonamira, uye zvigadzirwa zvekuchengeta munhu. Iyo yakakwira molecular uremu musiyano inonyanya kushanda pakupa viscosity.
   • Stabilizer: Inoshanda seyakadzikama mu emulsions uye suspensions, zvichiita kuti kugadzikana uye kufanana kwezvakagadzirwa.
   • Mvura Yekuchengeta Mumiriri: HEC ine yakanakisa yekuchengetedza mvura zvivakwa, zvichiita kuti ive yakakosha mune zvekuvaka, senge madhaka uye simende-yakavakirwa zvigadzirwa.
   • Pharmaceuticals: Muindasitiri yemishonga, HEC inoshandiswa sebhainda, disintegrant, uye thickener mukugadzirwa kwehwendefa. Yayo inonyungudika mumvura inoita kuti ive yakakodzera kune akasiyana siyana emuromo dosage mafomu.
   • Personal Care Zvigadzirwa: Inowanikwa mune zvekuzora, shampoos, uye lotions, HEC inopa viscosity uye kugadzikana kune magadzirirwo muindasitiri yekuchengeta munhu.
   • Indasitiri yeOiri neGasi: HEC inoshandiswa mukuchera zvinwiwa se rheology modifier uye fluid-kurasikirwa kwekudzora mumiririri.
6. Viscosity Control:
   • Iyo yakakwira molecular huremu hweHEC inobatsira pakubudirira kwayo mukudzora viscosity. Ichi chivakwa chakakosha mumashandisirwo uko ukobvu hunodiwa kana kuyerera kwechigadzirwa kunoda kuchengetedzwa.
7. Kuenderana:
   • HEC inowanzoenderana nehuwandu hwezvimwe zvinhu uye zvinowedzera zvinowanzoshandiswa mumaindasitiri akasiyana. Nekudaro, kuyedzwa kwekuenderana kunofanirwa kuitwa kana uchigadzira nezvimwe zvinhu.
8. Quality Standards:
   • Vagadziri vanowanzopa zvakatemwa uye zvemhando zviyero zveHEC zvigadzirwa, kuve nechokwadi chekuenderana uye kuvimbika mukuita. Aya mazinga anogona kusanganisira maitiro ane chekuita nehuremu hwemamorekuru, kuchena, uye zvimwe zvakakosha zvivakwa.

Hydroxyethyl cellulose ine huremu hwemamorekuru hwe1000000 ipolymer inoshanda zvakasiyana-siyana ine akasiyana mashandisirwo mumaindasitiri, kunyanya mumagadzirirwo ayo akakwira viscosity uye kunyungudika kwemvura zvinhu zvakakosha. Izvo zvakakosha kutevedzera zvinokurudzirwa nhungamiro uye magadzirirwo anopihwa nevagadziri kuti vawane mhedzisiro mune chaiwo maapplication.
