Dab tsi yog cov qib sib txawv ntawm cov tshuaj phais cellulose?

Ethylcellose yog cov polymer ntau yam los ntawm cellulose, lub ntuj polymer pom hauv cov nroj tsuag. Nws yog dav siv nyob rau hauv ntau yam kev lag luam vim tias nws cov khoom tshwj xeeb xws li high thermal stability, thiab yeeb yaj kiab kev muaj peev xwm. Cov qib ntawm cov tshuaj tua kab mob feem ntau yog qhov txawv txav raws li xws li molecular hnyav, degree ntawm kev tawm tsam, thiab lwm yam ntxwv tshwj xeeb.

1.Molecular hnyav:

Tsawg molecular hnyav ethylcellulose: cov qhab nia theem no muaj qis dua molecular hnyav thiab feem ntau siv raws li cov txheej txheem, cov nplaum, thiab kws tshuaj.
High molecular nyhav txiv neej cellulose: qhov hnyav molecular hnyav ethyl cellulose feem ntau yog siv nyob rau hauv cov ntawv thov uas yuav tsum muaj zog.

2. Qib ntawm ETHOXHYLATION:

Ethyl Cellulose tau muab los ntawm hloov cov pab pawg hydroxyl hauv cellulose nrog pab pawg. Cov degree ntawm kev tawm tsam cuam tshuam rau cov solubility thiab lwm yam khoom ntawm cov polymer. Qib uthoxylation tsawg dua hauv cov dej solubility nce ntxiv, thaum qib siab dua qib ua rau kev tswj cov tshuaj tshuaj thiab txheej txheej.

3. Kev sib xyaw nrog lwm cov polymers:

Qee cov qib ethylcelulose tshwj xeeb tau tsim tshwj xeeb los txhim kho kev sib xyaw nrog lwm cov polymers. Qhov no ua rau lawv haum rau siv sib xyaw ua kom tiav cov khoom siv uas xav tau.

4.Application:

Kws Tshuaj Ntsuam Xyuas Tshuaj: Txuj Ci feem ntau siv nyob rau hauv cov kws tshuaj muaj nyob hauv cov phau ntawv, zaj duab xis tsim tus neeg sawv cev, thiab matrix-tsim tus neeg sawv cev rau kev tso tawm cov ntaub ntawv.

Cov Txheej Txheem Qib: Ethylcellulose yog dav siv nyob rau hauv lub txheej txheej kev lag luam vim nws muaj peev xwm los ua cov yeeb yaj kiab ntshiab thiab hloov tau. Nws muab cov txheej txheem tiv thaiv rau cov ntsiav tshuaj, granules thiab tshuaj noj.

Number case thiab pleev xim qib: Qee qib kev ua nom ua mob tau siv hauv cov inks thiab xim pleev xim vim lawv cov yeeb yaj kiab ua yeeb yaj kiab thiab cov khoom nplaum.

Qib Adhesive: Ethylcellose tau siv nyob rau hauv cov nplaum vim tias nws muaj peev xwm los ua lub tawv tawv tseem yooj yim.

5. Txuj ci siab:

Muaj cov qhab-nees tshwj xeeb tshaj plaws ntawm cov neeg tawm tsam lub tshuaj xyuas kev kho rau cov ntawv thov tshwj xeeb. Piv txwv li, muaj kev txhim kho rheological cov khoom, txhim kho tso tawm cov yam ntxwv lossis sib xyaw nrog qee yam kuab tshuaj.

6. Kev tswj hwm ua raws li:

Cov qib kev kawm tau siv nyob rau hauv cov ntawv thov tshuaj thiab cov qauv kev tswj hwm cov qauv kev nyab xeeb kom ntseeg tau tias muaj feem xyuam.

Cov khoom tshwj xeeb thiab cov ntawv thov ntawm cov tshuaj tua kab mob yuav txawv txav chaw tsim khoom rau chaw tsim khoom lag luam thiab cov khoom siv thiab cov khoom siv xav tau. Yog xav paub cov ntaub ntawv ntxaws ntxiv nws pom zoo kom xa mus rau cov ntawv txheej txheem cov ntaub ntawv muab los ntawm cov khw.
