Ihe owuwu kemịkal nke cellulose ether derivatives

Ethslọ mkpụrụ osisi cellugul bụ ihe omimi nke cellulose, polysiccharide a hụrụ na mgbidi nke osisi. Ihe eji eme ihe ncheta nke ihe eji eme ihe eji eme ya site na mmeghe nke di iche iche other site na ngbanwe kemịkalụ nke hydroxyl (-O) dị iche iche molulus. A na-ahụkarị ụdị mkpụrụ osisi cellugul gụnyere:

1. Hydroxypylththth methylcellose (hpmc):
   • Ọdịbe:
     • HPMC bụ Synchazed site n'ijikọ ìgwè hydroxy na hydroxypyl (-Och2chohch3) na methyl (-och3).
     • Ogo nke nbanye (DS) na-egosi ọnụọgụ nke otu Hydyl n'otu n'otu glucose na mkpụrụ osisi cellulose.
2. Celloxymymym cellulose(CMC):
   • Ọdịbe:
     • A na-ewepụta CMC site na iwebata otu igbe carroxyyythyyl (otu -ch2COOH) dị iche iche na ìgwè hydroxy nke cellulose.
     • Consezọ ndị na-ebu ụzọ na-ebu ụzọ na-eme ka mmiri na-enye ya mmiri na agwaetiti.
3. Hydroxyethythythythythyth Cellulose (HEC):
   • Ọdịbe:
     • A na-enweta HEC site na iji otu Hydroxy dị iche iche cellulose na hydroxyethyl dị iche iche).
     • Ọ na-egosiputa mmiri na-eme ka mmiri na-eme ka mmiri dị mma.
4. Methyl cellulose (mc):
   • Ọdịbe:
     • A na-emepụta MC site na iwebata otu methyl (-och3) na ìgwè hydroxy nke cellulose.
     • A na-ejikarị ya maka njigide mmiri ya na ihe ndị na-akpụ akpụ ihe nkiri.
5. Ethyl cellulose (ec):
   • Ọdịbe:
     • EC bụ Sypesized site n'iji ìgwè hydroxy dochie otu Celdlose na ethyl (-OC2H5).
     • A maara ya maka enweghị nsogbu ya na mmiri ma na-ejikarịkarị ya mepụta mkpuchi na fim.
6. Hydroxypropyl Cellulose (HPC):
   • Ọdịbe:
     • A na-enweta HPC site na iwebata Hydropyl (-Och2chohch3) Otu dị iche iche na ìgwè Hydroxy.
     • A na-eji ya dị ka ihe mgbochi, ihe nkiri gara aga, na viscosity viofier.

Ihe owuwu ụfọdụ dịgasị iche maka mkpụrụ ndụ ọ bụla na-adabere na ụdị na ogo nke dochie nke edepụtara n'oge usoro mgbanwe kemịkalụ. Okwu mmeghe nke ndị a na-ekere òtù ahụ na-enye ndị a kapịrị ọnụ nke ọ bụla sel, na-eme ka ha doo anya maka ngwa dị iche iche.
