EipponCell MHEC LH 640M, eyiti o jẹ methyl hydroxyethyl cellulose, ni a maa n lo ni amọ-lile ti o gbẹ.Eyi ni apejuwe awọn aaye pataki ti a mẹnuba ninu aye:
Idaduro omi ti o dara: MHEC ṣe idaniloju pe amọ-lile naa ni idaduro omi ti o to, idilọwọ awọn oran bi iyanrin, powdering, ati idinku agbara ti o fa nipasẹ aipe omi ati aipe simenti hydration.O ṣe imudara iṣọkan, iṣẹ ṣiṣe, ati lile ti ọja naa.Bi iye ti MHEC ti ṣafikun, wahala ikore ati iki amọ ti amọ tun pọ si.
Aṣoju-afẹfẹ afẹfẹ: MHEC le ṣiṣẹ bi oluranlowo afẹfẹ.Akoonu afẹfẹ ti o ga julọ ninu amọ-lile ti waye nigbati iye MHEC jẹ 0.5%.Bibẹẹkọ, nigbati iye ba kọja 0.5%, akoonu afẹfẹ dinku diẹdiẹ, ti o yori si idinku agbara rọ ati agbara titẹ.
Imudarasi iṣẹ-ṣiṣe: Afikun ti MHEC n ṣe irọrun ohun elo didan ti amọ-layer tinrin ati amọ-lile.MHEC ṣe idaduro hydration ti awọn patikulu amọ, ati iwọn aropo (DS) ṣe ipa pataki ninu ilana hydration idaduro yii.Ipa ti akoonu methoxyl lori idaduro hydration jẹ pataki diẹ sii ju ti akoonu hydroxyethyl.
O ṣe pataki lati ṣe akiyesi pe ether cellulose ni ipa meji lori iṣẹ amọ.Imudara rẹ da lori lilo ti o yẹ;Lilo aibojumu le ni awọn ipa odi.Išẹ ti amọ-alupo ti o gbẹ ni ipa nipasẹ awọn okunfa gẹgẹbi ibamu ti ether cellulose ati iye ati ilana ti afikun.Ni awọn ohun elo ti o wulo, iru kan ti cellulose ether le yan, tabi awọn oriṣiriṣi oriṣiriṣi le ṣee lo ni apapo.
