Xasiloonida Ethers Cellulose

Xasiloonida ethers-ka cellulose waxaa loola jeedaa awoodda ay u leeyihiin in ay ilaashadaan hantidooda kiimikaad iyo jireed waqti ka dib, iyada oo loo marayo xaalado kala duwan oo deegaanka ah iyo cabbirrada habraaca. Waa kuwan qaar ka mid ah arrimaha saameeya xasilloonida ethers cellulose:

1. Xasilloonida Hydrolytic: Ether-ka Cellulose waxay u nugul yihiin hydrolysis, gaar ahaan xaaladaha acidic ama alkaline. Xasiloonida ethers-ka cellulose waxay ku xidhan tahay heerka beddelkooda (DS) iyo qaabdhismeedka kiimikada. Eter-yada cellulose-ka sare ee DS ayaa aad ugu adkeysanaya hydrolysis marka la barbar dhigo dhigooda DS hoose. Intaa waxaa dheer, joogitaanka kooxaha difaaca sida methyl, ethyl, ama kooxaha hydroxypropyl waxay kor u qaadi karaan xasilloonida hydrolytic ethers cellulose.
2. Xasiloonida Heerkulka: Ether-ka Cellulose waxa uu muujiyaa degganaansho kulayl oo wanaagsan marka la eego xaaladaha habaynta iyo kaydinta caadiga ah. Si kastaba ha ahaatee, soo-gaadhista dheer ee heerkulka sare waxay u horseedi kartaa hoos u dhac, taasoo keenta isbeddel ku yimaada viscosity, miisaanka unugyada, iyo sifooyinka kale ee jirka. Deganaanshaha kulaylka ethers cellulose waxay ku xiran tahay arrimo ay ka mid yihiin qaab-dhismeedka polymer, miisaanka kelli, iyo joogitaanka wakiilada xasilinta.
3. Xasiloonida pH: Ether-yada cellulose waxay ku xasilloon yihiin tiro balaadhan oo ah qiyamka pH, sida caadiga ah inta u dhaxaysa pH 3 iyo 11. Si kastaba ha ahaatee, xaaladaha pH ee ba'an waxay saameyn karaan xasiloonidooda iyo waxqabadkooda. Xaaladaha acidic ama alkaline waxay u horseedi karaan hydrolysis ama xaalufka ethers cellulose, taasoo keentay luminta viscosity iyo guryaha dhumucdooda. Foomamka ay ku jiraan ethers cellulose waa in lagu qaabeeyaa heerarka pH ee kala duwanaanshaha xasilloonida ee polymerka.
4. Xasilloonida Oxidative: Ether-ka Cellulose waxay u nugul yihiin xaalufka oksaydhiyaha marka ay la kulmaan ogsijiinta ama wakiilada oksaydhka. Tani waxay dhici kartaa inta lagu jiro habaynta, kaydinta, ama soo-gaadhista hawada. Antioxidants ama stabilizers ayaa laga yaabaa in lagu daro qaababka ether-ka cellulose si loo hagaajiyo xasilloonida oksaydhiyeyaasha loogana hortago xaalufka.
5. Xasilloonida Iftiinka: Ether-ka unugyadu guud ahaan way deggan yihiin soo-gaadhista iftiinka, laakiin soo-gaadhista muddada dheer ee shucaaca ultraviolet (UV) waxay u horseedi kartaa hoos u dhac iyo midab. Xasijiyeyaasha iftiinka ama nuugayaasha UV ayaa laga yaabaa in lagu dhex daro habab ay ku jiraan ethers cellulose si loo yareeyo xaalufka sawirka loona ilaaliyo xasilloonida alaabta.
6. Waafaqsanaanta Walxaha Kale: Deganaanshaha ether-ka cellulose waxaa saamayn ku yeelan kara isdhexgalka maaddooyinka kale ee habaynta, sida dareerayaasha, surfactants, cusbada, iyo waxyaabaha lagu daro. Tijaabada iswaafajinta waa in la sameeyaa si loo hubiyo in ether-ka cellulose-ku ay ahaato mid deggan oo aan la marin kala-soocida wajiga, roobabka, ama saameynaha kale ee aan loo baahnayn marka lagu daro qaybaha kale.

hubinta xasiloonida ethers cellulose waxay u baahan tahay si taxadar leh xulashada alaabta ceeriin, hagaajinta qaabaynta, xaaladaha habaynta saxda ah, iyo hababka kaydinta iyo maaraynta habboon. Wax-soo-saarayaashu waxay inta badan sameeyaan tijaabinta xasilloonida si ay u qiimeeyaan waxqabadka iyo nolosha shelf ee alaabada ether-ka ku jirta cellulose iyadoo lagu jiro xaalado kala duwan.
