I-Hydroxyethyl Methyl Cellulose (MHEC)
I-Methyl Hydroxyethyl Cellulose(MHEC/HEMC)
CAS:9032-42-2
I-Hydroxyethyl Methyl Cellulose(HEMC) ikwabizwa ngokuba yiI-Methyl Hydroxyethyl Cellulose(MHEC), i-ether ye-cellulose ene-versatile, ephezulu yokusebenza esetyenziswa njenge-ejenti ephezulu yokugcina amanzi, i-stabilizer, i-adhesives kunye ne-ejenti yokwenza ifilimu kwiintlobo zezixhobo zokwakha. Emva kokulungiswa kunye nonyango oluphezulu, sinokufumana iimpahla ezisasazwa emanzini ngokukhawuleza, sandise ixesha elivulekileyo, i-anti-sagging, njl.

Ulwakhiwo lweMichiza ye-MHEC
I-MHEC iveliswa nguetherifying cellulose yendalokunyeamaqela e-methyl kunye ne-hydroxyethyl. Olu hlengahlengiso luphuculaukunyibilika kwamanzi, viscosity, kunye nokuhambelanangezinto ezahlukeneyo.
Iimpawu eziphambili ze-MHEC:
- Ukunyibilika kwamanzi: Ukunyibilika emanzini ashushu nabandayo, ukwenza izisombululo ezicacileyo.
- Ukuqina kwamandla: Ibonelela nge-viscosity ephezulu kunye nolawulo oluhle kakhulu lwe-rheology.
- Ukugcinwa kwamanzi: Kunqanda ukulahleka kwamanzi kwiimveliso ezisekelwe kwisamente kunye ne-gypsum, ukuphucula ukunyanga kunye nokubambelela.
- Ubume be-Non-Ionic: Iyahambelana noluhlu olubanzi lweekhemikhali, kubandakanywa neetyuwa kunye ne-surfactants.
- Amandla okwenza iFilimu: Yenza iifilimu eziguquguqukayo kunye nezizinzileyo, ezinenzuzo kwiingubo kunye nokusetyenziswa kwamayeza.
- Uzinzo lwe-Thermal: Ukumelana nobushushu, okwenza kube yinto efanelekileyo kwizicelo zobushushu obuphezulu.

Izinto eziluncedo zokuSebenzisa i-MHEC
✔ Ukugcinwa kwamanzi okugqwesileyo - Kunqanda ukomisa kwangaphambi kwexesha kulwakhiwo kunye nezicelo zokuthambisa.
✔ Ukubambelela okuphuculweyo -Ukuphucula amandla okudibanisa kwi-adhesives kunye ne-mortars.
✔ Izinzile Kuluhlu olubanzi lwe-pH-Isebenza ngokufanelekileyo kwiindawo ezineasidi, ezingathathi hlangothi, kunye ne-alkaline.
✔ Ukuhambelana kwe-non-Ionic-Isebenza kakuhle ngeetyuwa, ii-surfactants, kunye nezinye iipolymers.
✔ Iphucula i-Rheology kunye nePropati eQuquzelayo-Ivumela i-viscosity elawulwayo, inqanda ukuthontsiza kunye nokuntywila.
