Hydroxyethylcellulose (HEC) bụ nonionic, mmiri na-soluble polima nke sitere na cellulose.N'ihi ihe na-eme ka ọ sie ike, na-eme ka ọ kwụsie ike na gelling, a na-ejikarị ya na ụlọ ọrụ dị iche iche, gụnyere nlekọta onwe onye na mpaghara ọgwụ.N'ime ụwa mmanu mmanu, a na-ejikarị hydroxyethyl cellulose eme ihe dị ka rheology modifier iji meziwanye viscosity na n'ozuzu arụmọrụ nke ngwaahịa.
1. Okwu Mmalite nke Hydroxyethyl Cellulose (HEC):
Nkọwa na nhazi nke hydroxyethyl cellulose.
Njirimara nke HEC na-eme ka ọ dị mma maka ngwa mmanu mmanu.
Nye nkọwapụta nkenke nke isi mmalite na mmepụta ya.
2. Ọrụ nke hydroxyethyl cellulose na mmanu mmanu:
Njirimara Rheological na mmetụta ha na lubricating mmanụ viscosity.
Ndakọrịta na usoro dị iche iche.
Melite arụmọrụ mmanu mmanu na nkwụsi ike.
3. Usoro mmanu mmanu nwere HEC:
Ihe mmanu mmiri na-eme ka mmiri: HEC dị ka isi ihe.
Ndakọrịta na ihe ndị ọzọ mmanu mmanu.
Mmetụta na udidi na mmanu mmanu.
4. Ngwa nke HEC mmanu:
Mmanya nkeonwe: na-akwalite mmekọrịta chiri anya na nkasi obi.
Mmanya ụlọ ọrụ: Melite arụmọrụ na ndụ.
Mmanya ọgwụ: Ngwa dị na ụlọ ọrụ nlekọta ahụike.
5. Uru nke mmanụ mmanye HEC:
Biocompatibility na nchekwa echiche.
Belata esemokwu na iyi na ngwa dị iche iche.
Emelitere nkwụsi ike na ndụ nchekwa.
6. Ihe ịma aka na ngwọta:
Ihe ịma aka ndị nwere ike ime na imepụta HEC.
Usoro iji merie nkwụsi ike na nsogbu ndakọrịta.
Kwalite itinye uche HEC maka ngwa dị iche iche.
7. Ntụle usoro iwu:
Soro ụkpụrụ ụlọ ọrụ na ụkpụrụ.
Ntụle nchekwa na ọmụmụ toxicology.
Ndokwa aha maka ngwaahịa nwere HEC.
8. Ọmụmụ ihe gbasara ikpe:
Ọmụmatụ nke mmanu mmanu dị na azụmaahịa nwere HEC.
Ntụle arụmọrụ na nzaghachi onye ọrụ.
Tụnyere usoro mmanụ mmanu ndị ọzọ.
9. Usoro na mmepe n'ọdịnihu:
Nnyocha na-aga n'ihu na mpaghara nke HEC lubricants.
nwere ike ọhụrụ na ngwa ọhụrụ.
Echiche gburugburu ebe obibi na nkwado.
10. Nkwubi okwu:
Nchịkọta isi okwu mkparịta ụka.
Na-emesi ike na mkpa HEC dị na nhazi mmanu mmanu.
Ọdịnihu na mmepe na ngalaba a.
Nnyocha zuru oke nke mmanụ mmanye sitere na hydroxyethylcellulose kwesịrị inye nghọta nke ọma maka ngwa ha, uru, ihe ịma aka, na ihe ga-eme n'ọdịnihu.
