Nguwuphi umahluko phakathi kwe-HPMC kunye ne-MHEC?

I-Hydroxypropyl Methylcelcelgalose (HPMC) kunye ne-Methmc) naseMethylhydroxyyl seluplose Ngelixa zinokufana, zibonisa umahluko ophambili.

Hydroxypropyl methylcelceltulose (HPMC):

1.Kwazisa uMgangatho:
I-HPMC yi-polymer ye-semi-sydhemetic ethathwe kwi-sellulose.
Ineyunithi ephindaphindayo ye-anhydroglucose edityaniswe ne-hydroxypropy kunye namaqela e-AFGISY.

2. Ukusebenza:
Ukuluka kwamanzi: I-HPMC inyibilikiswa emanzini kwaye ke isetyenziswa ngokubanzi kwiifom ezahlukeneyo.
Ukwenza ifilimu: Inokwenza iifilimu ezincinci, zenza ukuba zilungele izicelo ezifuna iingubo ezikhuselayo.
Ingcambu ye-shirmal: Inepropathi ye-thermal yentshutshiso, enokuba yingenelo kwizicelo ezithile.

3. Isicelo:
Amayeza: Isetyenziswe njengamabhanti, ukurhweba ngefilimu kunye nematriki ekhutshwayo kwiitafile zamachiza amachiza.
Ishishini lokwakha: Isetyenziswe kwii-Cacehevers esekwe kwi-cemences, iiplanga ezisekwe kwi-gypsim ezisekwe kunye nokuzibandakanya.
Umzi-mveliso wokutya: Isetyenziswe njenge-tickener kunye ne-stiblizer ekutyeni.

4. Imveliso:
Iveliswa yi-ether ye-seluplose nge-propylene oxide ne methyl chloride.
Inqanaba lokufakwa endaweni (DS) limisela umyinge we-hydroxypropy kunye namaqela e-AMAFISY.

I-Methylhylhydroxylcelcelcelcelose (MHC):

1.Kwazisa uMgangatho:
I-MHEC ikwasisisele i-selsulose ikhutshiwe nge-hydroxyyteyl kunye namaqela e-AFGISY eqhotyoshelwe kwi-Selebose BackBone.

2. Ukusebenza:
I-Solubang Water: Njenge-HPMC, i-MHC inyibilikisiwe amanzi, eyenza igalelo lokuqalisa ukusebenza kwezicelo ezahlukeneyo.
Ukuphuculwa kwamanzi okugcinwa kwamanzi: I-MHC ngokubanzi ibonisa ukugcinwa kwamanzi okungcono kune-HPMC.

3. Isicelo:
Ishishini lokwakha: isetyenziswe ngokubanzi njenge-arhente yokuthambisa ngenxa yezifakelo ezisekwe kwisamente, iifowuni zeTilles kunye neGypsim esekwe.
Iipeyinti kunye neengubo: izenzo njengezilungiso ze-Rheoology kwiipeyinti ezisekwe emanzini kunye neengubo.
Amayeza: Isetyenziselwa ukulungiswa kwamayeza.

4. Imveliso:
Iveliswe ngu-Ether of selsulose ne-methyl chloride kunye ne-ethyl chloride.
Inqanaba lokufaka ichaphazela iipropathi kunye nokusebenza kwe-MHETCS.

Umahluko phakathi kwe-HPMC kunye ne-MHEC:

I-1. Inkqubo ye-Etheristion:
I-HPMC iqeshelwe ukusebenzisa i-propylene oxide kunye ne methyl chloride.
I-MHC iveliswa kusetyenziswa i-methyl chloride kunye ne-etimy chloride.

2. Ukugcinwa kwamanzi:
I-MHEC ngokubanzi ibonisa iipropathi ezingcono zamanzi kwi-HPMC.

3. Isicelo:
Ngelixa kukho ezinye ii-overlap, isicelo esithile sinokukhetha enye kwenye indlela esekwe kwiimpawu zayo ezizodwa.

4. Ukuhla kwe-shirmal:
I-HPMC ibonisa iipropathi ze-thermoge, ngelixa i-MHEC inokuba nendlela eyahlukileyo yengqolowa.

I-HPMC kunye ne-MHC inoluhlu olubanzi lwezicelo kumashishini ahlukeneyo, kwaye nganye ineengenelo ezizodwa. Ukukhetha phakathi kwabo kuxhomekeke kwiimfuno ezithile zesicelo kunye nentsebenzo efunekayo. Nokuba kukwindawo yamayeza, ukwakhiwa okanye amanye amasimi, ukuqonda umahluko kuyanceda ukwenza izigqibo ezinolwazi ukufezekisa intsebenzo kunye neenkqubo ezahlukeneyo.
