Ọdịdị Molecular:
Njirimara ngwaahịa:
1. Ọdịdị: HEMC dị ọcha ma ọ bụ ihe fọrọ nke nta ka ọ bụrụ ntụ ntụ; enweghị isi na enweghị ụtọ.
2. Solubility: Ụdị H dị na HEMC nwere ike ịgbaze na mmiri n'okpuru 60 ℃, na ụdị L nwere ike ịgbaze na mmiri oyi. HEMC bụ otu ihe ahụ dị ka HPMC ma bụrụ nke a na-apụghị ịsacha n'ahụ n'ọtụtụ ihe mgbaze organic. Mgbe ọgwụgwọ elu gasịrị, HEMC na-agbasa na mmiri oyi na-enweghị agglomeration ma na-agbaze nwayọọ nwayọọ, ma ọ nwere ike ịgbaze ngwa ngwa site n'ịgbanwe uru PH ya na 8-10.
3. Nkwụsi ike uru PH: Viscosity na-agbanwe ntakịrị n'ime oke nke 2-12, na viscosity na-emebi karịa oke a.
4. Ịdị mma: ọnụego ngafe nke 80 mesh bụ 100%; ngafe nke 100 ntupu bụ ≥99.5%.
5. Ụgha kpọmkwem ike ndọda: 0.27-0.60g / cm3.
6. The decomposition okpomọkụ dị n'elu 200 ℃, na ọ na-amalite na-ere ọkụ na 360 ℃.
7. HEMC nwere nnukwu nkwụsi ike, nkwụsi ike nkwusioru, dispersibility, cohesiveness, moldability, njigide mmiri na àgwà ndị ọzọ.
8. N'ihi na ngwaahịa nwere hydroxyethyl otu, gel okpomọkụ nke ngwaahịa ruru 60-90 ℃. Na mgbakwunye, otu hydroxyethyl nwere hydrophilicity dị elu, nke na-emekwa ka ọnụ ahịa jikọtara ọnụ ahịa dị mma. Karịsịa n'ime ụlọ na-ekpo ọkụ ma dị elu n'oge okpomọkụ, HEMC nwere njigide mmiri dị elu karịa methyl cellulose nke otu viscosity, na ọnụ ọgụgụ njide mmiri adịghị ala karịa 85%.
