Methyl Hydroxyethyl Cellulose (MHEC/HEMC)
CAS:9032-42-2
Cellulose-ka Hydroxyethyl Methyl (HEMC) waxaa sidoo kale loo yaqaan sidaMethyl Hydroxyethyl Cellulose(MHEC), waa qalab cellulose ether oo tayo sare leh oo loo isticmaalo sidii wakiil haynta biyaha oo hufan, xasiliye, dhejisyo iyo wakiil sameeya filimada noocyada qalabka dhismaha. MHEC/HEMC si weyn ayaa loogu isticmaalaa codsiyada warshadaha, sida dhismaha, saabuunta, rinjiga iyo dahaarka, waxaan sidoo kale bixin karnaa HEMC iyadoo loo eegayo shuruudaha macaamiisha. Ka dib marka wax laga beddelo oo la daweeyo dusha sare, waxaan heli karnaa alaabta si dhakhso ah loogu kala firdhiyo biyaha, loo dheereeyo waqtiga furan, ka hortagga jabka, iwm.

Qaab-dhismeedka Kiimikada ee MHEC
MHEC waxaa soo saaraycellulose dabiici ah oo nadiifiyaoo lehkooxaha methyl iyo hydroxyethylWax-ka-beddelkan ayaa hagaajiyamilmida biyaha, dheellitirka, iyo iswaafajintaoo leh agab kala duwan.
Astaamaha Muhiimka ah ee MHEC:
- Biyuhu waxay milmaan: Waxay ku milmaan biyaha kulul iyo kuwa qabowba, iyagoo sameeya xalal cad.
- Awooda Qaro-dhalinta: Waxay bixisaa dheellitir sare iyo xakamaynta rheology-ga oo aad u fiican.
- Haynta Biyaha: Waxay ka hortagtaa lumitaanka biyaha ee alaabada ku salaysan sibidhka iyo kuwa ku salaysan gypsum, iyadoo hagaajinaysa bogsashada iyo isku dhejinta.
- Dabeecad Aan Ionic ahayn: Waxay la jaanqaadi kartaa noocyo badan oo kiimikooyin ah, oo ay ku jiraan milixda iyo walxaha dusha sare leh.
- Awoodda Samaynta Filimada: Waxay abuurtaa filimaan dabacsan oo waara, oo faa'iido u leh dahaarka iyo codsiyada dawooyinka.
- Xasiloonida Kulaylka: Waxay u adkaysataa kulaylka, taasoo ka dhigaysa mid ku habboon codsiyada heerkulka sare.

Faa'iidooyinka Isticmaalka MHEC
✔ Haynta Biyaha oo Aad u Fiican - Waxay ka hortagtaa qallajinta degdega ah ee dhismaha iyo qurxinta.
✔ Ku dhegid la xoojiyay - Waxay hagaajisaa xoogga isku xidhka ee dhejisyada iyo hoobiyaha.
✔ Xasilloon oo ku baahsan baaxadda pH ee ballaaran - si wax ku ool ah ayuu uga shaqeeyaa deegaannada aashitada, dhexdhexaadka ah, iyo kuwa alkaline-ka ah.
✔ La jaanqaadida aan Ionic ahayn - Si fiican ayuu ula shaqeeyaa cusbooyinka, surfactants-ka, iyo polymers-yada kale.
✔ Waxay hagaajisaa sifooyinka Rheology iyo Socodka - Waxay u ogolaataa daxalka la xakameeyey, iyadoo ka hortageysa daadashada iyo libdhidda.
