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%.

Mkpa

Dị ka onye na-arụ ọrụ n'elu, hydroxyethyl methyl cellulose HEMC nwere àgwà ndị a na mgbakwunye na ịgbatị, nkwụsịtụ, njikọ, emulsifying, imepụta ihe nkiri, mgbasa, na-ejigide mmiri na inye colloid nchebe:

(1) Hydroxyethyl methyl cellulose HEMC bụ soluble na mmiri ọkụ ma ọ bụ oyi, na-eme ka ọ nwee ọtụtụ ihe solubility na njirimara viscosity, ya bụ, gelation na-abụghị thermal;

(2) Hydroxyethyl methyl cellulose HEMC nwere ike ibikọ ọnụ n'ọtụtụ dịgasị iche iche nke polymers ndị ọzọ na-edozi mmiri, surfactants, na salts, ma bụrụ ihe dị mma maka ngwọta electrolyte dị elu;

(3) HEMC nwere njigide mmiri siri ike karịa methyl cellulose, na nkwụsi ike ya viscosity, dispersibility, na mildew resistance dị ike karịa nke hydroxyethyl cellulose.

Usoro nkwadebe ngwọta

(1) Tinye akọrọ ọnụ mmiri dị ọcha na akpa;

(2) Tinye hydroxyethyl methyl cellulose HEMC n'okpuru mkpali dị ala, ma kpalie ruo mgbe niile hydroxyethyl methyl cellulose na-agbaze nke ọma;

(3) N'ihi data nyocha teknụzụ anyị, a na-atụ aro ka ịgbakwunye ya mgbe agbakwunyere emulsion polymer (ie, hydroxyethyl methyl cellulose HEMC na-ejikọta ya na ethylene glycol ma ọ bụ propylene glycol).
