Falanqaynta iyo soo koobitaanka ee natiijooyinka baaritaanka chetter ee chetter sedexda cutub, gunaanadka ugu weyn waa sida soo socota:
5.1 Gunaanad
1. Ethe cellr Soo saarista dhirta dhir cawska
(1) Waxyaabaha ka kooban shan nooc oo dhir ah oo dhir ah
iyo Bagrasse si ay u soo saaraan cellulose, iyo habka soo saarista unugyada ayaa la hagaajiyay. Xaaladaha habraaca ee la hubo,
Daahirsanaanta qaraabada lighellosuse, ceyrta qamadiga qamadiga iyo cellulose clutselose dhammaantood waxay ahaayeen 90%, iyo wax-soo-saarkooda ayaa dhammaantood ahaa 40%.
.
Markay tahay 1510 cm-1 (gariirka qalfoofka ee giraanta benzene) iyo ku dhawaad 1730 cm-1 (oo fidsan gariir gariir ah ee carbony-ga aan lagu dulqaadan karin c = o)
Ma jirin wax ugu badan oo ugu sarreeya, oo muujinaya in Lignin iyo nabarrada loo soo saaray badeecada soo saartay asal ahaan laga saaray, waxaana loona soo saaray cellulose cellulose uu safka sare u saarayo. by guduud
Waxaa laga arki karaa muuqaalka ka maqnaanshaha dibedda ee ah in qof qaraabo ah ee Lign uu si isdaba joog ah u dhaco si isdaba joog ah ka dib tallaabo kasta oo dawooyin ah, iyo maqnaanshaha UV qaadashada unugyada unugyada ee la helay.
Qalooca muuqaalka ah ee la helay waxay ku dhowaatay galka qalooca ee cagta ee muuqaalka muuqaalka ah ee KP MENSASIATEN, oo muujinaya in unugyada uu heysto uu saafiyey. by x
Falanqaynta Raajada Raajada ee Raadinta ayaa muujisay in qaraabada qaraabada ah ee ciribtirka sheyga la soo saaray si weyn loo hagaajiyay.
2. Diyaarinta anshaxa cellulose
(1) Tijaabada kaliya ee qodobka waxaa loo isticmaalay in lagu saadaalinayo alkali-ka alkali-ka sicir-bararka ah ee ka-hortagga ah ee unugyada unugyada pine-ka;
Tijaabooyin orthogonal ah iyo tijaabooyin hal-cunno ah ayaa laga fuliyay diyaarinta CMC, HEC iyo HECMC oo ka socota unugyada alkali ee alkali alwaax, siday u kala horreeyaan.
Kordhinta. Marka la eego geedi socodka diyaarinta habboon ee ugu habboon, cmc oo leh ds illaa 1.237, HEC oo ay la galeen Ms ilaa 1.657 la helay.
iyo Hecmc oo leh DS ah 0.869. (2) Sida laga soo xigtay falanqaynta Ftiir, marka la barbar dhigo cudurka alwaaxda asalka ah, gaarigabymethyl ayaa si guul leh loo geliyay cmc cmc cmc.
Gudaha celliose ether HEC, kooxda hydroxytytyletyl si guul leh ayaa loogu xiray; Cellulose Etter HECMC, kooxda hydroxytyletylyl ayaa si guul leh ugu xirmay
Carboxmethyl iyo kooxaha hydroxytyl.
(3) Waxaa laga heli karaa falanqaynta H-NMR in kooxda hyroxytyletyl lagu soo rogay sheyga HEC, iyo HEC waxaa lagu helaa xisaabinta fudud.
darajada mashiinka ah ee beddelka.
(4) Sida uu sheegayo falanqaynta XRD, marka la barbar dhigo unugyada alwaaxda asalka ah, ee kanta-hoosaadka kaynta ee CMC, HEC iyo Heecmc waxay leeyihiin a
Foomamka Crystal All dhammaantood waxaa loo beddelay nooca cellulose II, oo qudhunka si weyn ayuu usii wasakhaysan yahay.
3. Codsiga cell celther chether certe
(1) Hantida aasaasiga ah ee koollada asalka ah: SA, CMC, HEC iyo HEC iyo Hecmc dhamaantood waa dareeraha pseudoplastic-ga, iyo
Saddexda ka mid ah ee saddexda ka mid ah ee keli ah ee keli ah ee keli ah ee keli ah ayaa ka wanaagsan kan SA, oo marka la barbar dhigo SA, waxay leedahay PVI hoose, oo ku habboon daabacaadda qaababka wanaagsan.
Ubaxa; Amarka heerka samaynta koollada ah ee afarta ka mid ah waa: sa> cmc> Hecmc> HEC; Awoodda biyaha ee haysta CMC asalka ah ee CMC,
72
Awood u ah urea iyo cusbada ka-hortagga-ka-hortagga sting s waa la mid ah SA, iyo xasilloonida kaydinta ee CMC asalka ah ayaa ka fiican kan, laakiin
Awood u leh farta ceyriinka ee HEC ayaa ka sii liita tan SA;
Iskaashaalka iyo xasilloonida dhiigga ee sodium bicarbonate ayaa ka xun sah;
SA waa isku mid, laakiin biyuhu hayaan awooda, is-waafajinta sodium bicarbonate iyo xasilloonida kaydinta ee Herecmc ceyriinka ayaa ka hooseeya sa. (2) Daabacaadda Feejirka ee Faste: CMC muuqaalka muuqaalka ah ee dhalidda iyo qalad, daabacaadda, daabacaadda cabashada, iwm ayaa u dhigma SA.
iyo heerka ugu sareeya ee CMC way ka fiican tahay tan SA; Xaddiga ugu sareeya ee daabacaadda iyo daabacaadda dareenka HEC waxay la mid yihiin SA, laakiin muuqaalka HEC ayaa ka fiican kan Sa.
Mugga midabka leh, ee faquuqa iyo qaabka midabka ee xoqidda ayaa ka hooseeya sayga SA; Daabacaadda 'Hecmc Daabacaadda' Hecmc Daabacaadda, Soonka midabka ee xoqidda ayaa la mid ah SA;
Saamiga gutaarka ayaa ka sarreeya SA, laakiin xasilloonida midabka muuqata iyo keydinta ee Hecmc ayaa ka hooseysa sa.
5.2 Talooyinka
Saameynta Codsiga ee 5.1 Cilmiga unugyada ee Cilmiga ee Chether Chether waa la heli karaa, prot cluther clither waxaa loo isticmaali karaa farta firfircoon
Daabacaadda dheeh, gaar ahaan aaladda unugyada unugyada anionic. Sababo la xiriira soo bandhigida Carddrophilic Grodxrophimethyl, lixda xubnood ee
Fikradda ah kooxda hydroxyl kooxda hydroxyl ee giraanta, iyo khidmadda taban ka dib markii la mid ah, waxay kor u qaadi kartaa dheehida dheecaanka fiilooyinka oo leh daadad falcelin ah. Si kastaba ha noqotee, gebi ahaanba,
Saamaynta arjiga ee cellulose ether ether ee prot ma ahan mid aad u wanaagsan, gaar ahaan sababta oo ah heerka beddelka ama galka galka ah ee chether celther.
Sababta oo ah heerka hoose ee beddelka, diyaarinta qolalka kelida ee leh shahaadada hoose ee shahaadada sare ama shahaadada sare ee beddelka ayaa u baahan waxbarasho dheeri ah.
