Sii Ethyl Hydroxyethyl Cellulose

Ethyl hydroxyethyl cellulose (EHEC) waa derivative cellulose la beddelay oo isku daraya sifooyinka ethyl cellulose (EC) iyo hydroxyethyl cellulose (HEC). Waxaa caadi ahaan loo isticmaalaa sidii dhumuc, xidhidh, iyo wakiilka filim samaynta ee warshado kala duwan, oo ay ku jiraan dawooyinka, waxyaalaha la isku qurxiyo, alaabta daryeelka shakhsi ahaaneed, iyo daahan.

EHEC waxaa sida caadiga ah soo saara iyada oo ka falcelinaysa ethyl chloride leh hydroxyethyl cellulose iyada oo lagu jiro xaalado la xakameeyey. Beddelka kiimikaadkan wuxuu soo bandhigayaa kooxaha ethyl ee lafta dhabarka hydroxyethyl cellulose, taasoo keentay badeecad leh milmayn la xoojiyey, viscosity, iyo sifooyinka samaynta filimada marka la barbar dhigo derivatives cellulose aan la beddelin.

Waxyaabaha muhiimka ah iyo sifooyinka ethyl hydroxyethyl cellulose (EHEC) waxaa ka mid ah:

1. Wakiilka dhumucda: EHEC waxay u shaqeysaa sidii wakiilka dhumuc wax ku ool ah ee xalalka aqueous, kordhinta viscosity iyo hagaajinta sifooyinka rheological ee hababka.
2. Binder: EHEC waxa loo isticmaalaa sida xidhe ahaan foomamka qiyaasta adag sida kiniiniyada iyo granules ee hababka daawooyinka. Waxay gacan ka geysataa hagaajinta isku-xidhka iyo isku-buufinta budada, fududaynta samaynta kiniiniyada oo leh maaddo isku mid ah oo daroogo ah iyo sifooyinka kala-baxa.
3. Filimkii Hore: EHEC waxay samayn kartaa filimo dabacsan oo waara marka la marsado meelaha sare. Gurigani wuxuu ka dhigayaa mid faa'iido u leh dahaarka, rinjiyada, dhejiska, iyo alaabta daryeelka shakhsi ahaaneed halkaas oo la rabo filimka ilaalinta ama qurxinta.
4. Biyihii: EHEC waxay soo bandhigaysaa milanka biyaha oo hagaagay marka la barbar dhigo ethyl cellulose, taas oo u oggolaanaysa in si fudud loo kala firdhiyo oo lagu daro hababka aqueous.
5. Waafaqid: EHEC waxay la jaanqaadi kartaa noocyo kala duwan oo maaddooyin kale oo caadi ahaan loo isticmaalo dawooyinka, waxyaalaha la isku qurxiyo, iyo dahaarka, oo ay ku jiraan polymers kale, balaastikada, surfactants, iyo maaddooyinka firfircoon.
6. Xasilloonida: EHEC waxay ku xasilloon tahay xaalado kala duwan oo pH ah iyo heerkulbeegyo, taasoo ka dhigaysa mid ku habboon in loo isticmaalo qaabab kala duwan oo leh shuruudo habaysan oo kala duwan.
7. Kala duwanaansho: EHEC waxay ka heshaa codsiyada noocyo kala duwan oo badeecooyin ah, oo ay ku jiraan kaniiniyada dawooyinka, qaababka la mariyo, rinjiga, dahaarka, xabagta, iyo alaabta daryeelka shakhsi ahaaneed, taas oo ay ugu wacan tahay sifooyinkeeda kala duwan iyo waafaqsanaanta maaddooyinka kale.

Guud ahaan, ethyl hydroxyethyl cellulose (EHEC) waa derivative cellulose qiimo leh oo kala duwan ee codsiyada kala duwan ee warshadaha kala duwan, oo bixiya milanka, viscosity, iyo guryaha-samaynta filimada marka la barbar dhigo derivatives cellulose aan la beddelin.
