Ethylcellulose waa polymer-ka shaqeeya ee kala duwan oo laga soo qaatay cellulose iyada oo loo marayo hordhaca kooxaha ethyl. Wax ka beddelkaani wuxuu siinayaa polymer-ka sifooyin gaar ah, taasoo ka dhigaysa mid ku habboon codsiyada warshadaha kala duwan. Arrin muhiim ah oo ka mid ah ka faa'iidaysiga ethylcellulose dhinacyo kala duwan waa fahamka habdhaqankiisa kala diris maadaama ay saamaynayso habaynteeda iyo codsigeeda.
Habka kala dirida ethylcellulose:
Guryaha milmay:
Sababtoo ah dabeecadda hydrophobic ee beddelka ethyl, ethylcellulose wax yar bay ku milmi kartaa biyaha. Si kastaba ha ahaatee, waxay soo bandhigaysaa milmayn ee noocyo kala duwan oo dareere organic ah, taasoo ka dhigaysa mid si gaar ah ugu habboon codsiyada halka caabbinta biyuhu ay muhiim tahay. Xalka caadiga ah ee ethylcellulose waxaa ka mid ah ethanol, ethyl acetate, methylene chloride, iyo toluene. Habka kala diriddu waxay ku lug leedahay jebinta xoogagga intermolecular gudaha polymerka, taas oo u oggolaanaysa dareeraha inuu galo oo kala firdhiyo silsiladaha polymerka.
Waxyaabaha saameeya kala dirida:
Dhowr arrimood ayaa saameeya kala dirida ethylcellulose:
Xulashada xalinta: Doorashada xalinta waxay door muhiim ah ka ciyaartaa habka kala dirida. Alaabooyinka xidhiidh sare leh ee ethylcellulose, sida ethyl acetate, waxay dedejin doontaa milanka.
Heerkulka: Kordhinta heerkulka guud ahaan waxay kordhisaa heerka kala dirida sababtoo ah waxay siisaa tamar dheeraad ah isdhexgalka polymer-solvent. Si kastaba ha ahaatee, heerkulka xad dhaafka ah ayaa laga yaabaa inuu keeno hoos u dhac.
Cabbirka qurubka polymerka: Cabbirka walxaha yar wuxuu bixiyaa meel sare oo weyn oo loogu talagalay isdhexgalka dareeraha, taasoo keentay kala diri degdeg ah. shiididda habboon ama farsamooyinka dhimista cabbirka ayaa loo isticmaali karaa si loo hagaajiyo kala dirida.
Fasalka Polymer: Darajada ethylcellulose waxaa lagu go'aamiyaa nuxurka ethoxy iyo miisaanka kelli, kaas oo saameeya milmihiisa. Maadada ethoxy ee sare waxay guud ahaan kordhisaa milanka.
Kicinta ama kicinta: Kicinta makaanikada ama kicinta waxay sahlaysa dhexgalka dareeraha gudaha matrixka polymer waxayna deddejisaa habka kala dirida.
Hababka kala dirida ee inta badan la isticmaalo:
Habab dhowr ah ayaa loo isticmaali karaa in lagu milo ethylcellulose:
Isku-dhafka Xalka: Tani waxay ku lug leedahay isku-darka ethylcellulose iyo dareere ku habboon oo walaaqaya isku-darka ilaa ay si buuxda u milmaan. Habkan waxaa badanaa lagu isticmaalaa goobaha shaybaadhka.
Dahaarka buufinta: Codsiyada warshadaha, xalalka ethylcellulose ayaa inta badan loo diyaariyaa habka daahan buufinta. Walxuhu wuu uumi baxaa, isaga oo ka tagaya filim khafiif ah oo ethylcellulose ah substrate-ka.
Dixinta dhalaalka kulul: Farsamadani waxay ku lug leedahay kuleylinta isku dar ah ethylcellulose iyo qaybo kale oo loo beddelo xaalad dhalaalaysa ka dibna lagu sii daayo dhimasho. Ka dib marka la qaboojiyo, ethylcellulose ayaa adkaata.
Fahamka sifooyinka kala dirida iyo hababka ayaa muhiim u ah ku-habaynta ethylcellulose codsiyada gaarka ah.
Isticmaalka ugu muhiimsan ee ethyl cellulose:
Warshadaha dawooyinka:
Dahaarka Kiniinka: Ethylcellulose waxaa si weyn loogu isticmaalaa sida walxaha dahaarka ee kiniiniyada si ay u bixiyaan sii daynta la xakameeyey oo loo ilaaliyo maaddooyinka firfircoon ee dawooyinka.
Microencapsulation: Waa tignoolajiyada microencapsulation ee loo isticmaalo hababka gudbinta daroogada si looga ilaaliyo daawooyinka arrimaha deegaanka.
warshadaha cuntada:
Dahaarka la cuni karo: Ethylcellulose waxa loo isticmaalaa daahan la cuni karo oo ku saabsan miraha iyo khudaarta si ay u kordhiyaan noloshooda shelf iyo ilaalinta cusub.
Rinjiyeynta iyo Dahaarka:
Khadadka iyo Dahaarka: Ethylcellulose waa shay caadi ah oo ku jira khadadka iyo dahaarka, taasoo bixisa sifooyin filim samaynta iyo kor u qaadida xasilloonida qaabaynta.
Warshadaha caagagga ah:
Isku-darka Polymer: Waxaa loo isticmaalaa sida wax lagu daro balaastikada si loo hagaajiyo sifooyinkooda farsamaynta, u qaybiyaan dabacsanaan iyo adkaanta.
Xabag:
Xabagta dhalaalaysa Kulul: Ethylcellulose waxa loo isticmaalaa samaynta xabagta dhalaalaysa ee kulul si ay uga caawiso hagaajinta sifadooda koollada iyo isku xidhka.
Warshadaha dharka:
Cabbirka Dharka: Habaynta dharka, ethylcellulose waxaa loo isticmaalaa cabbiridda si ay u siiso dahaadh difaac ah fiilooyinka una kordhiso xooggooda.
alaabta elektarooniga ah:
Qalabka sawir-qaadista: Sababo la xiriira sameynta filimada iyo sifooyinka dielectric, ethylcellulose waxaa loo isticmaali karaa in lagu sameeyo filimada khafiifka ah ee qalabka elektaroonigga ah, oo ay ku jiraan unugyada qorraxda.
Alaabooyinka daryeelka shakhsi ahaaneed:
Nadaamka la isku qurxiyo: Waxa loo isticmaalaa sidii dhumuc iyo xasiliye marka la isku qurxiyo waxyaabaha la isku qurxiyo sida kiriimyada iyo labeennada.
Daabacaadda 3D:
Xirayaasha daabacaadda 3D: Ethylcellulose waxaa loo isticmaali karaa sidii xire ee habka daabacaadda 3D, ka caawinta ilaalinta sharafta qaab dhismeedka shayga daabacan.
Warshadaha waraaqaha:
Daahan warqad: Ethyl cellulose waxaa loo isticmaalaa daahan warqad ah si loo hagaajiyo sifooyinka dusha sare, kor loogu qaado daabacaadda iyo bixinta caabbinta biyaha
Ethylcellulose waxay leedahay codsiyo warshado kala duwan sababtoo ah sifooyinkeeda milmay ee gaarka ah iyo sifooyinka shaqada badan. Hababka kala diridda ayaa ah arrin muhiim ah oo lagu xaqiijinayo kartidooda, taasoo u sahlaysa in lagu xalliyo baahiyo gaar ah. Maaddaama sayniska polymer uu sii wado horumarka, ethylcellulose ayaa laga yaabaa inay door muhiim ah ka ciyaarto noocyo kala duwan oo codsiyo cusub ah, oo gacan ka geysanaya horumarinta alaabta iyo alaabta horumarsan.
