Ethyl Cellulose (EC)
Sharaxaada Alaabta
Ethyl Cellulose (EC) waa bilaa dhadhan, qulqulaya, caddaan ilaa iftiin budo leh. Waxa loo isticmaalaa suntan jelka, kiriimyada, iyo labeennada. Tani waa ether-ka cellulose. Caadi ahaan, Ethyl Cellulose EC waxaa loo isticmaalaa sidii qayb aan barar ahayn, oo aan la milmi karin oo ku jirta nidaamka shaxanka ama dahaarka.
Ethyl Cellulose EC waxa loo isticmaali karaa in lagu dahaadho hal ama in ka badan maaddooyinka firfircoon ee kiniinka si looga hortago in ay la falgalaan walxo kale ama midba midka kale. Waxay ka hortagi kartaa midabaynta walxaha si fudud oxidizable sida ascorbic acid, u oggolaanaya granulations kiniinnada si fudud loo cufan iyo foomamka kale ee qiyaasta dahaarka ee qaybo yaryar, pellets iyo kiniinnada.
Ethyl cellulose kuma milmi karto biyaha, laakiin waxay ku milmi karaan dareerayaal badan oo organic ah, sidaa darteed EC ayaa loo isticmaalaa kiniiniyada, granules ee wakiilka koollada. Waxay kordhin kartaa adkaanta kiniinnada si loo yareeyo kiniiniyada friability, waxaa loo isticmaali karaa sida wakiilka filim-samaynta si loo hagaajiyo muuqaalka kiniiniga, dhadhanka go'doonsan, si looga fogaado fashilka daawooyinka biyaha xasaasiga ah si looga hortago qulqulka wakiilada isbeddelka metamorphic, kor u qaadista kaydinta badbaadada leh ee kiniiniyada, sidoo kale waxa loo isticmaali karaa sidii walax xoojinaysa kiniiniyada sii daynta joogtada ah.

EC waxaa lagu milmi karaa noocyo kala duwan oo organic ah, dareeraha caadiga ah (saamiga mugga):
1)Toluene:Ethanol = 4:1
2)Ethanol
3)Acetone:Isopropanol = 65:35
4)Toluene:Isopropanol = 4:1
Methyl Acetate:Methanol = 85:15

Codsiyada
Ethyl Cellulose waa resin hawleed badan. Waxay u shaqeysaa sidii xire, dhumuc weyn, rheology beddele, filim hore, iyo xannibaad biyo codsiyo badan sida hoos lagu faahfaahiyey:
Xabagta: Ethyl Cellulose waxa si balaadhan loogu isticmaalaa dhalaalidda kulul iyo xabagta kale ee dareeraha ku salaysan si ay u noqoto heerkulbeeg heersare ah iyo xoog cagaaran. Waxay ku milmi kartaa polymers kulul, balaastiijiyeyaasha, iyo saliidaha.
Dahaarka: Ethyl Cellulose waxay siisaa biyo-celin, adayg, dabacsanaan iyo dhalaal sare oo rinji iyo dahaarka ah. Waxa kale oo loo isticmaali karaa dahaar gaar ah oo ay ka mid yihiin xaashida xidhiidhka cuntada, nalalka dhaadheer, saqafyada, dhaldhalaalka, lacquers, varnishes, iyo dahaarka badda.
Ceramics: Ethyl Cellulose waxaa si weyn loogu isticmaalaa dhoobada loo sameeyay codsiyada elektarooniga ah sida capacitors dhoobada lakabka badan. Waxay u shaqeysaa sidii binder iyo rheology modifier. Waxa kale oo ay bixisaa xoog cagaaran oo gubanaya iyada oo aan hadhaaga.
Khadadka Daabacaadda: Ethyl Cellulose waxa loo isticmaalaa hababka khad-ku-salaysan ee dareeraha ah sida qalin-jilicsanaanta, qallafsanaanta iyo daabacaadda shaashadda. Waa organosoluble oo si aad ah ula jaan qaada balaastikada iyo polymers. Waxay bixisaa rheology hagaagtay iyo guryaha xidhitaan taas oo ka caawisa samaynta of xoog sare iyo filimada iska caabin ah.
