Cov tshuaj ntxuav HEMC

Cov tshuaj ntxuav HEMCHydroxyethyl methylcellulose yog ib hom hmoov dawb uas tsis muaj ntxhiab, tsis muaj saj, thiab tsis muaj tshuaj lom uas yaj tau hauv dej txias kom ua tau ib qho kua nplaum pob tshab. Nws muaj cov yam ntxwv ntawm kev ua kom tuab, kev sib txuas, kev sib kis, kev sib xyaw, kev tsim zaj duab xis, kev ncua, kev nqus, kev sib xyaw, kev ua kom gelation, kev ua haujlwm ntawm qhov chaw, kev khaws cia noo noo thiab kev tiv thaiv colloid. Vim tias cov kua dej muaj cov haujlwm ua haujlwm ntawm qhov chaw, nws tuaj yeem siv ua cov colloid tiv thaiv, emulsifier thiab dispersant. Hydroxyethyl methyl cellulose aqueous solution muaj hydrophilicity zoo thiab yog ib qho tshuaj zoo rau kev khaws cia dej.

Cov tshuaj ntxuav HEMCHydroxyethylMethylCellulosehu ua Methyl Hydroxyethyl Cellulose (MHEC), Nws yog npaj los ntawm kev qhia txog ethylene oxide substituents (MS 0.3～0.4) rau hauv methyl cellulose (MC). Nws qhov kev kam rau ntsev zoo dua li ntawm cov polymers tsis hloov kho. Qhov kub ntawm gel ntawm methyl cellulose kuj siab dua li ntawm MC.

HEMC rau qib tshuaj ntxuav tes yog hmoov dawb lossis daj me ntsis, thiab nws tsis muaj ntxhiab, tsis muaj saj thiab tsis muaj tshuaj lom. Nws tuaj yeem yaj rau hauv dej txias thiab cov kuab tshuaj organic los tsim cov tshuaj viscous pob tshab. Cov kua dej muaj kev ua haujlwm ntawm qhov chaw, pob tshab siab, thiab ruaj khov, thiab nws cov kev yaj hauv dej tsis cuam tshuam los ntawm pH. Nws muaj cov teebmeem thickening thiab anti-freezing hauv cov tshuaj zawv plaub hau thiab cov tshuaj da dej gels, thiab muaj cov dej khaws cia thiab cov khoom zoo rau cov plaub hau thiab daim tawv nqaij. Nrog rau kev nce ntxiv ntawm cov khoom siv raw, kev siv cellulose (antifreeze thickener) hauv cov tshuaj zawv plaub hau thiab cov tshuaj da dej gels tuaj yeem txo cov nqi thiab ua tiav cov txiaj ntsig xav tau.

Cov yam ntxwv ntawm cov khoom:

1. Kev yaj: yaj tau hauv dej thiab qee cov kuab tshuaj organic. HEMC tuaj yeem yaj hauv dej txias. Nws qhov kev sib xyaw siab tshaj plaws tsuas yog txiav txim siab los ntawm viscosity. Kev yaj hloov pauv nrog viscosity. Qhov viscosity qis dua, qhov solubility ntau dua.

2. Kev tiv taus ntsev: Cov khoom HEMC yog cov cellulose ethers uas tsis yog ionic thiab tsis yog polyelectrolytes. Yog li ntawd, thaum muaj cov ntsev hlau lossis cov electrolytes organic, lawv ruaj khov hauv cov kua dej, tab sis kev ntxiv cov electrolytes ntau dhau tuaj yeem ua rau cov gels thiab nag lossis daus.

3. Kev Ua Haujlwm Ntawm Qhov Chaw: Vim tias cov kua dej muaj kev ua haujlwm ntawm qhov chaw, nws tuaj yeem siv ua tus neeg sawv cev tiv thaiv colloidal, emulsifier thiab dispersant.

4. Thermal gel: Thaum cov khoom HEMC aqueous kua raug cua sov rau qee qhov kub, nws dhau los ua opaque, gels, thiab precipitates, tab sis thaum nws txias tas li, nws rov qab mus rau lub xeev kua qub, thiab cov gel thiab nag lossis daus no tshwm sim Qhov kub feem ntau nyob ntawm lawv cov roj nplua nyeem, cov khoom pab ncua, cov colloids tiv thaiv, emulsifiers thiab lwm yam.

5. Kev tsis muaj zog ntawm cov metabolism thiab tsis muaj ntxhiab tsw qab thiab tsw qab: Vim tias HEMC yuav tsis raug metabolized thiab muaj ntxhiab tsw qab thiab tsw qab tsawg, nws yog siv dav hauv cov khoom noj thiab tshuaj.

6. Kev tiv thaiv pwm: HEMC muaj peev xwm tiv thaiv kab mob zoo thiab ruaj khov viscosity zoo thaum lub sijhawm khaws cia ntev.

7. PH ruaj khov: Qhov viscosity ntawm HEMC cov khoom aqueous kua tsis tshua cuam tshuam los ntawm acid lossis alkali, thiab tus nqi PH ruaj khov nyob rau hauv qhov ntau ntawm 3.0-11.0.

Cov Khoom Qib

Daim ntawv thov ntau yam ntawm cov tshuaj lom neeg txhua hnub cellulose HEMC:

Siv rau hauv tshuaj zawv plaub hau, tshuaj ntxuav lub cev, tshuaj ntxuav ntsej muag, tshuaj pleev, tshuaj pleev, gel, toner, tshuaj pleev plaub hau, cov khoom siv styling, tshuaj txhuam hniav, tshuaj ntxuav qhov ncauj, dej ua npuas ua si.

Lub luag haujlwm ntawmtshuaj ntxuav tesqib cellulose HEMC:

Hauv cov ntawv thov kom zoo nkauj, nws feem ntau yog siv rau kev ua kom cov khoom zoo nkauj tuab, ua npuas dej, ruaj khov emulsification, dispersion, adhesion, zaj duab xis tsim thiab txhim kho kev ua haujlwm ntawm dej, cov khoom muaj viscosity siab yog siv los ua thickening, thiab cov khoom muaj viscosity qis yog siv rau kev ncua thiab dispersion. Zaj duab xis tsim.

Pkev ntim khoom, kev pov tseg thiab kev cia khoom

(1) Ntim rau hauv hnab yas polyethylene lossis hnab ntawv, 25KG / hnab;

(2) Khaws cov cua kom ntws hauv qhov chaw cia khoom, tsis txhob cia tshav ntuj ncaj qha, thiab khaws cia deb ntawm cov chaw hluav taws;

(3) Vim tias hydroxyethyl methyl cellulose HEMC yog hygroscopic, nws yuav tsum tsis txhob raug rau huab cua. Cov khoom tsis siv yuav tsum tau kaw thiab khaws cia, thiab tiv thaiv kom tsis txhob muaj dej noo.
