Piv txwv xws li kev tswj-tso tshuaj formulations thiab nyias txheej ntawm cov ntsiav tshuaj.

2. Medium viscosity qib:

Qhov nruab nrab molecular hnyav thiab viscosity.
Nws yog dav siv nyob rau hauv kev lag luam kws tshuaj rau sustained-tso formulations, qhov twg qhov sib npaug ntawm txheej thickness thiab tso tawm tus nqi yog qhov tseem ceeb.
Kuj tseem siv rau hauv kev tsim cov nplaum tshwj xeeb thiab cov sealants.

3. High viscosity qib:

Cov qib no muaj qhov hnyav dua molecular thiab yog li cov viscosities siab dua.
Zoo tagnrho rau cov ntawv thov uas xav tau cov txheej tuab lossis cov yeeb yaj kiab.
Siv rau hauv kev tsim cov txheej tiv thaiv xws li inks, xim thiab varnishes.

4. Fine-grained qib:

Cov qib no muaj qhov loj me me, uas pab ua kom cov coatings smoother thiab txhim kho dispersion hauv cov kev daws teeb meem.
Nrhiav cov ntawv thov rau cov tshuab luam ntawv zoo thiab cov txheej txheem los npaj cov chaw zoo.

5. Cov qib siab ethoxy cov ntsiab lus:

Ethylcellulose nrog qib siab ntawm ethoxylation.
Muab kev ua kom zoo dua solubility nyob rau hauv ntau yam ntawm cov kuab tshuaj.
Siv nyob rau hauv daim ntawv thov xav tau ntau dua solubility polymers, xws li tej yam tshuaj formulations.

6. Tsawg noo noo qib qib:

Ethyl cellulose nrog txo cov dej noo.
Qhov zoo tshaj plaws rau cov ntawv thov uas tsis muaj dej noo yog qhov kev txhawj xeeb, xws li kev tsim cov tshuaj dej-rhiab heev.

7. Thermoplastic qib:

Cov qib no qhia txog kev coj tus cwj pwm zoo dua.
Siv nyob rau hauv molding daim ntaub ntawv uas cov ntaub ntawv yuav tsum tau softened thiab zoo li tus nyob rau hauv high kub.

8. Tswj kev tso tawm theem:

Tsim los rau cov tshuaj formulations uas yuav tsum tau tswj cov tshuaj tso tawm nyob rau lub sij hawm ntev.
Tsim kom ua tiav qhov kev tso tawm kinetics thaum tswj kev ruaj ntseg.

Kev siv ntawm ethylcellulose:

1. Tshuaj:

Tswj tso tshuaj npaj.
Tablet coatings rau saj masking thiab tswj dissolution.
Binder rau granules hauv kev tsim cov ntsiav tshuaj.

2. Coatings thiab inks:

Kev tiv thaiv txheej rau ntau qhov chaw.
Printing inks rau flexographic thiab gravure printing.
Automotive thiab industrial txheej.

3. Adhesives thiab sealants:

Tshwj xeeb adhesives rau ntau yam kev siv.
Sealants siv rau cov pob qij txha thiab sealing hauv kev tsim kho thiab kev tsim khoom.

4. Khoom noj khoom haus kev lag luam:

Cov txheej txheem ntawm cov txiv hmab txiv ntoo thiab zaub ua rau lub neej txee.
Encapsulation ntawm flavors thiab fragrances.

5. Plastics thiab Moulding:

Thermoplastic cwj pwm hauv kev siv molding.
Tsim cov khoom yas tshwj xeeb.

6. Cov khoom siv hluav taws xob:

Siv hauv kev tsim cov txheej txheem tiv thaiv rau cov khoom siv hluav taws xob.

nyob rau hauv xaus:
Ntau qib ntawm ethylcellulose muaj nyob rau kom tau raws li ntau yam kev siv hauv kev lag luam sib txawv.Los ntawm cov kws tshuaj mus rau cov txheej txheem thiab cov nplaum, ethylcellulose muaj ntau yam nyob hauv nws cov qib sib txawv, txhua tus tsim los ua kom tau raws li cov kev xav tau tshwj xeeb.Raws li kev siv thev naus laus zis thiab kev lag luam yuav tsum tau hloov zuj zus mus ntxiv, kev txhim kho cov qib ethylcellulose tshiab nrog cov khoom txhim kho tuaj yeem ua lub luag haujlwm tseem ceeb hauv kev ua kom tau raws li cov kev xav tau ntawm cov ntawv thov tshiab.Kev nkag siab txog qhov sib txawv ntawm cov qib no ua rau cov tuam txhab xaiv cov ethylcellulose uas tsim nyog tshaj plaws rau lawv daim ntawv thov tshwj xeeb, kom ntseeg tau tias kev ua tau zoo thiab kev ua haujlwm zoo.
