Kutheni i-MHEC ikhethwa ngaphezu kwe-HPMC ye-Cellulose Ether

I-Methyl Hydroxyethyl Cellulose (MHEC) ngamanye amaxesha ikhethwa ngaphezu kwe-Hydroxypropyl Methylcellulose (HPMC) kwizicelo ezithile ngenxa yeempawu zayo ezithile kunye neempawu zokusebenza.Nazi ezinye izizathu zokuba kutheni i-MHEC inokukhethwa kune-HPMC:

1. Ugcino lwaManzi olomeleziweyo: I-MHEC inika amandla aphezulu okugcina amanzi xa kuthelekiswa ne-HPMC.Lo mhlaba uluncedo kakhulu kwizicelo apho ugcino lokufuma lubaluleke kakhulu, njengodaka olusekwe kwisamente, iiplaster esekwe kwigypsum, kunye nezinye izinto zokwakha.
2. UkuPhuculwa kokuSebenza okuPhuculweyo: I-MHEC inokuphucula ukusebenza kunye nokuhambelana kweefomyula ngenxa yomthamo wayo ophezulu wokugcina amanzi.Oku kwenza kube lula ukuxuba kunye nokusebenzisa kwizicelo zokwakha, okukhokelela ekugqityweni okugudileyo kunye nokusebenza okungcono jikelele.
3. Ixesha elingcono lokuvula: I-MHEC inokubonelela ixesha elide lokuvula xa kuthelekiswa ne-HPMC kwi-adhesives yokwakha kunye ne-tile mortars.Ixesha elide elivulekileyo livumela ixesha elide lokusebenza ngaphambi kokuba izinto ziqale ukuseta, ezinokuthi zibe luncedo kwiiprojekthi zokwakha ezinkulu okanye phantsi kweemeko ezinzima zokusingqongileyo.
4. Ukuzinza kwe-Thermal: I-MHEC ibonisa ukuzinza okungcono kwe-thermal xa kuthelekiswa ne-HPMC kwimiqulu ethile, eyenza ukuba ifaneleke kwizicelo apho ukuvezwa kwamaqondo okushisa aphezulu okanye ukuhamba ngebhayisikili ye-thermal kulindeleke.
5. Ukuhambelana kunye neZongezo: I-MHEC inokubonisa ukuhambelana okungcono kunye nezongezo ezithile okanye izithako eziqhelekileyo ezisetyenziswa ekuqulunqweni.Oku kunokukhokelela ekusebenzeni okuphuculweyo kunye nokuzinza kwizicelo ezahlukeneyo.
6. Iingqwalasela zoLawulo: Kweminye imimandla okanye imizi-mveliso, i-MHEC inokukhethwa kune-HPMC ngenxa yeemfuneko ezithile zolawulo okanye ukhetho.

Kubalulekile ukuqaphela ukuba ukhetho lwe-cellulose ether luxhomekeke kwiimfuno ezithile zesicelo ngasinye, kubandakanywa iimpawu ezinqwenelekayo, imilinganiselo yokusebenza, kunye nemimiselo yolawulo.Ngelixa i-MHEC inokubonelela ngeenzuzo kwizicelo ezithile, i-HPMC ihlala isetyenziswa ngokubanzi kwaye ikhethwa kwezinye izicelo ezininzi ngenxa yokuguquguquka kwayo, ukufumaneka, kunye nokusebenza okuqinisekisiweyo.
