Ethylcellulose waa polymer isku dhafan oo leh codsiyo laga helo warshado kala duwan, oo ay ku jiraan dawooyinka, dahaarka, koollada iyo cuntada.Darajooyinka kala duwan ee ethylcellulose waxaa loo habeeyey si ay u buuxiyaan shuruudo gaar ah marka la eego viscosity, miisaanka kelli iyo sifooyinka kale.

Qaab dhismeedka cellulose ethyl:

Ethylcellulose waa nooc ka mid ah cellulose, oo ah polymer dabiici ah oo laga helo gidaarada unugyada dhirta.Ethylation of cellulose waxay ku lug leedahay soo bandhigida kooxaha ethyl ee shaqada hydroxyl (-OH) ee cellulose.Dib-u-habayntani waxay siinaysaa ethylcellulose sifooyin gaar ah, taasoo ka dhigaysa mid ku milma dareerayaasha organic iyo bixinta awoodaha filim samaynta heer sare ah.

Astaamaha ethylcellulose:

Solubility: Ethylcellulose waxay ku milmi kartaa noocyo kala duwan oo dareere dabiici ah, sida khamriga, ketones, esters, iwm.
Guryaha filimada-samaynta: Guryaha filim-samaynta ee ugu fiican, oo ku habboon daboolka iyo filimada.
Thermoplasticity: Ethylcellulose waxa ay muujisaa hab-dhaqan heerkulbeeg ah, taas oo u oggolaanaysa in la qaabeeyo ama la sameeyo marka la kululeeyo.
Inert: Waa kiimiko ahaan aan firfircoonayn, oo bixisa xasillooni codsiyo kala duwan.

Fasalada Ethylcellulose:

1. Heerka viscosity hoose:

Darajooyinkani waxay leeyihiin miisaan unugyo ah oo hooseeya sidaas darteedna mawgu hooseeyo.

Tusaalooyinka waxaa ka mid ah hababka dawooyinka ee la xakameeyey iyo dahaarka dhuuban ee kiniinnada.

2. Heerka viscosity dhexdhexaad ah:

Miisaanka unugyadu dhexdhexaadka yahay iyo viscosity.
Waxaa si weyn loogu isticmaalaa warshadaha dawooyinka qaabaynta sii-daynta joogtada ah, halkaas oo dheellitirka u dhexeeya dhumucda daahan iyo heerka siideynta ay muhiim tahay.
Waxa kale oo loo isticmaalaa soo saarista xabagta khaaska ah iyo shaabadeynta.

3. Heerka viscosity sare:

Darajooyinkani waxay leeyihiin miisaan sare oo unugyo ah sidaas darteedna muuqaalkoodu sarreeyo.
Ku habboon codsiyada u baahan daaha ama filimada qaro weyn.
Loo isticmaalo soo saarista dahaarka ilaalinta sida khadadka, rinjiyada iyo faashka.

4. Heer wanaagsan:

Darajooyinkani waxay leeyihiin cabbirro qaybo yaryar, kuwaas oo ka caawiya inay dahaarka ka dhigaan kuwo siman oo wanaajiya kala firdhisanaanta xalalka.
Soo hel codsiyada khadadka daabacaadda tayada sare leh iyo dahaarka loogu talagalay diyaarinta dusha sare.

5. Darajooyinka ka kooban ethoxy sare:

Ethylcellulose oo leh heerar sare oo ethoxylation ah.
Waxay siisaa milmayn la xoojiyey oo kala duwan oo dareere ah.
Loo isticmaalo codsiyada u baahan polymers milmay sare, sida daawooyinka daawooyinka qaarkood.

6. Heerka qoyaanka oo hooseeya:

Ethyl cellulose oo leh qoyaan yar oo qoyaan ah.
Ku habboon codsiyada halka dareenka qoyaanku yahay walaac, sida soo saarista dawooyinka xasaasiga ah ee biyaha.

7. Heerarka heerkulbeegga:

Darajooyinkani waxay muujinayaan habdhaqan heerkulbeeg ah oo la xoojiyay.
Waxaa loo adeegsadaa codsiyada qaabeynta halkaasoo alaabada loo baahan yahay in la jilciyo laguna qaabeeyo heerkul sare.

8. Heerka sii daynta la xakameeyey:

Naqshadeynta daawooyinka dawooyinka ee u baahan in daawada la xakameeyey la sii daayo muddo dheer.
Loogu talagaly si loo gaaro kinetics-ka sii-deynta la rabo iyadoo la ilaalinayo xasilloonida.

Codsiyada ethylcellulose:

1. Daawooyinka:

Diyaarinta dawooyinka siideynta la xakameeyey.
Dahaarka kiniinka loogu talagalay maaskaro dhadhanka iyo kala dirida la xakameeyey.
Qalab loogu talagalay granules ee soo saarista kiniinka.

2. Dahaarka iyo khadadka:

Dahaarka ilaalinta ee dusha kala duwan.
Khadadka daabacaadda flexographic iyo gravure.
Dahaarka baabuurta iyo warshadaha.

3. Xabagta iyo shaabadda:

Xabagta gaarka ah ee codsiyada kala duwan.
Xirmooyinka loo isticmaalo kala-goysyada iyo xidhitaanka dhismaha iyo wax-soo-saarka.

4. Warshadaha cuntada:

Dahaarka la cuni karo ee miraha iyo khudaarta ayaa kordhiya nolosha shelf.
Soo koobida dhadhanka iyo udgoonka.

5. Caagagga iyo Dhalinta:

Dabeecadda Thermoplastic ee codsiyada qaabeynta.
Waxay soo saartaa alaab caag ah oo khaas ah.

6. Alaabta elegtarooniga ah:

Loo isticmaalo soo saarista dahaarka ilaalinta qaybaha elektiroonigga ah.

Gabagabadii:
Darajooyin kala duwan oo ethylcellulose ah ayaa diyaar u ah inay buuxiyaan codsiyo kala duwan oo warshado kala duwan ah.Laga soo bilaabo dawooyinka ilaa dahaarka iyo xabagta, ethylcellulose's isbedbedelkeeda waxay ku jirtaa darajooyinkeeda kala duwan, mid walbana loogu talagalay inuu daboolo baahiyo gaar ah.Maaddaama shuruudaha tignoolajiyada iyo warshadaha ay sii kobcayaan, horumarinta darajooyinka ethylcellulose cusub oo leh sifooyin la xoojiyey ayaa laga yaabaa inay door muhiim ah ka ciyaaraan buuxinta baahiyaha codsiyada soo baxaya.Fahamka farqiga u dhexeeya darajooyinkan ayaa awood u siinaya soosaarayaasha inay doortaan ethylcellulose ugu habboon codsigooda gaarka ah, iyagoo hubinaya waxqabadka ugu fiican iyo hufnaanta.
