Warshadda cuud ee china ecyl
Unugyada ceylka ah kuma baabiin karo biyaha, laakiin wuxuu ku milmi karaa waxyaabo badan oo dabiici ah, sidaa darteed EC ayaa loo adeegsaday kiniiniyada, granules ee wakiilka kudhaca. Waxay kordhin kartaa kaniiniyada si loo yareeyo kiniiniyada naxdinta leh, waxaa loo istcimaali karaa in wakiilka sameynta filimka, kor u qaadida kaydinta loo yaqaan 'metamorphity' si looga hortago in la soo kordhiyo kiniiniyada, sidoo kale waxaa loo istcimaali karaa sidii loo xoojin lahaa waxyaabaha kiniiniga sii-deynta ee joogtada ah.

EC waxaa lagu kala diri karaa koofiyadaha kala duwan ee dabiiciga ah, sida ethanol, isopropyl aalkolo, aalkolo kale, ketones, ketones, udgoon iyo wixii la mid ah. Xaddiga caadiga ah ee dareeraha ah (saamiga mugga):
1) Toluene: Ethanol = 4: 1
2) ethanol
3) acetone: isoptopanol = 65:35
4) Toluene: isopropanol = 4: 1
5) methyl acetate: methanol = 85:15
Codsiyada
Etyl cellulose waa resin meherad badan. Waxay u shaqaysaa sidii xayiraad, dhumuc weyn, dhexdhexaadka rheology, oo filiber hore, iyo biyuhu ku dhegan yihiin codsiyo badan oo codsiyo badan leh sida hoos lagu faahfaahiyay:
Daabacaadda inks: celylyl byelyl waxaa loo isticmaalaa nidaamyada khaladaadka ee ku saleysan xalka, dabaqa iyo daabacaadda shaashadda. Waa abaabulo oo aad u habboon oo la jaan qaadayayaasha balaastikada ah iyo polymers. Waxay bixisaa rheology la wanaajiyey iyo guryaha la wanaajinayo ee ka caawiya samaynta filimaanta xoogga badan iyo filimaanta iska caabbinta.
Dhalmada Waxay ku milmaysaa polymers kulul, gacaliyeyaasha, iyo saliidaha.
Xirmooyinka: Celylyl celluleyl waxay bixisaa biyuhu, adag, dabacsanaan iyo gariir sare ilaa rinjiyeynta iyo jaakadaha. Waxaa sidoo kale loo isticmaali karaa khafiifinta khaaska ah sida waraaqaha isku xirka cuntada, nalka iftiinka, saqafka, saqafka, suuxinta, dheecaanka, vales-ka, varnie-ka.
Cagaalada: Oldyl celyel-ka ayaa si aad ah loogu adeegsadaa dhoobada loo sameeyay codsiyada elektiroonigga ah sida cajaradaha isku-xidhka ee isku-xidhka (MLCC). Waxay u shaqaysaa sidii wax yar oo labajibbaaran. Waxay sidoo kale bixisaa xoog cagaaran oo gubanaya hadhaaga la'aan.
Codsiyada kale: Adeegsiga cellulose eethyl wuxuu u adeegsadaa codsiyada kale sida nadiifiyeyaasha, baakadaha dabacsan, saliidaha, iyo nidaam kasta oo ku saleysan xalka kale ee xallinta.
