Maxay ethylcellulose ka samaysan tahay?

Ethyl cellulose waa polymer synthetic oo ka soo jeeda cellulose dabiiciga ah, qayb dhismeed oo caadi ah oo ka mid ah derbiyada unugyada dhirta. Soo saarista ethyl cellulose waxay ku lug leedahay wax ka beddelka kiimikaad ee cellulose dabiiciga ah iyadoo la adeegsanayo ethyl chloride iyo kicin si loo soo saaro ethyl ether derivative of cellulose.

Nidaamku wuxuu ku bilaabmaa nadiifinta cellulose ee ilaha dhirta, sida saxarka alwaax ama suufka. cellulose-ka la safeeyey ayaa markaa lagu milmaa isku-dar ah dareerayaasha, sida ethanol iyo biyo, si loo sameeyo xal viscous ah. Ethyl chloride ayaa markaa lagu daraa xalka, oo ay weheliso kicin, kaas oo fududeeya falcelinta u dhaxaysa cellulose iyo ethyl chloride.

Inta lagu jiro falcelinta, molecule ethyl chloride molecule wuxuu bedelayaa qaar ka mid ah kooxaha hydroxyl ee silsiladda cellulose, taasoo keentay sameynta ethyl cellulose. Heerka ethoxylation, ama tirada kooxaha ethyl ee ku xiran unug kasta oo gulukoos ee silsiladda cellulose, waa la xakameyn karaa inta lagu jiro falcelinta si loo soo saaro ethyl cellulose oo leh sifooyin kala duwan iyo sifooyinka milanka.

Ka dib marka falcelinta la dhammeeyo, ethyl cellulose ee ka soo baxa waa la nadiifiyaa oo la qalajiyaa si looga saaro wixii haray ee dareeraha ama wasakhda. Shayga ugu dambeeya waa budo cad ama huruud ah oo ku milma noocyo kala duwan oo dareere dabiici ah, laakiin aan lagu milmin biyaha.

Guud ahaan, ethyl cellulose waa polymer synthetic kaas oo ka soo jeeda cellulose dabiiciga ah iyada oo loo marayo habka wax ka beddelka kiimikada kaas oo ku lug leh ku darida kooxaha ethyl ee silsiladda cellulose.
