Iziphumo zovavanyo lwe-Ethel

Ngohlalutyo kunye nesishwankathelo seziphumo zovavanyo lwe-Selesese Teluplose Kings kwizahluko ezintathu, izigqibo eziphambili zezi zilandelayo:

5.1 ISIQINISEKISO

1. Isellulose etheR Ukukhutshwa kwezixhobo zesityalo

.

kunye nengxowa yokukhupha i-seluplose, kwaye inkqubo yokukhupha i-seluplose yenziwe. Phantsi kweemeko ezifanelekileyo zenkqubo,

Ukucoceka ngokulalana kwiLiginoceLsulose, i-Straw yengqolowa ye-Sellulose kunye neBantasse Selelse yayingaphezulu kwe-90%, kwaye izivuno zabo zazingaphezulu kwe-40%.

.

Kwi-1510 cm-1 cm-1

Kwakungekho zincopho, zibonisa ukuba i-LIGIN kunye ne-heminsulose kwimveliso ekhutshiweyo bezisuswe, kwaye i-Selelose yafumana ubunyulu obukhulu. ngemipu emnyama

Ingabonwa ukusuka kwi-viecture yangaphandle yokufunxa ukuba umxholo onesihlobo se-LIGIN ukwehla ngokuqhubekayo emva kwenqanaba ngalinye lonyango, kwaye ukufunxa i-UV ye-UVOSEse ihla.

Ijika le-curct efunyenweyo lalikufuphi ne-Ultraviolet ye-Ultraviolet ye-PETASTRAL ye-potassium engaqhelekanga, ebonisa ukuba i-Selelose ifunyenwe icocekile. ngu-x

Uhlalutyo lwe-X-Ray Drafraction lubonise ukuba i-rystarity yesalamane ye-seluplose ifumene iphuculwe kakhulu.

2. Ukulungiswa kwe-Selese

.

Iimvavanyo ze-Orthogonal kunye neemvavanyo zezinto ezingatshatanga zenziwa ngokulungiselela i-CMC, i-hec kunye ne-hecmc ukusuka kwi-pine will alkali sellulose, ngokulandelelana.

Ulungiselelo. Phantsi kweenkqubo zokulungiselela ezifanelekileyo, i-CMC ene-DS ukuya kuthi ga kwi-1.237, i-HEC ene-MS ukuya kwi-1.657 yafunyanwa.

kunye ne-hecmc ene-DS ye-0.869. .

Kwi-selsulose ether hec, iqela le-hydroxyyl lixhunyiwe ngempumelelo; Kwi-SeleseEse Ether HecMC, iqela le-hydroxyyl lixhunyiwe ngempumelelo

I-carboxymethyl kunye ne-hydroxyyl amaqela.

.

isidanga se-molar sokufakwa endaweni.

.

Iifom zekristale zonke zitshintshiwe kwi-selsulose che, kwaye i-crystalliestity inciphile kakhulu.

3. Ukusetyenziswa kwe-selsulose ether paste

.

I-pseudeoplastity yezithunzi ezintathu zeselsese ilunge ngakumbi kuneso se-SA, kwaye xa kuthelekiswa ne-SA, inexabiso eliphantsi le-PVI, elilungele ngakumbi ekuprintweni iipateni ezilungileyo.

Ntyatyambo; I-odolo yomgangatho wokulungelelanisa amaphepha e-paste yee-pastes ezine ngu: SA> CMC> Hecmc> Hec; Amanzi abambe amandla e-CMC yoqobo,

72

Ukungqinelana kwe-Urea kunye netyuwa ye-anti-i-swins kuyafana ne-SA, kunye nokugcinwa kokugcina kwe-CMC yePasika ilunge ngakumbi kune-SA, kodwa

Ukungqinelana kwe-HEC Raw Raw kubi kakhulu kune-SA;

Ukuhambelana nokuzinza kwe-sodium bicarbonate kubi ngakumbi kune-SA;

I-SA iyafana, kodwa amanzi aphethe amandla, kodwa ungqinelana ne-sodium bicarbonate kunye nokugcinwa kozinzo lwe-heecmc Raw iphantsi kwe-SA. .

kwaye inqanaba le-quaste le-CMC lingcono kuneso se-SA; Izinga le-quaste kunye nokushicilelwa kweemvakalelo zeHec ziyafana ne-SA, kodwa imbonakalo ye-hec ilunge ngakumbi kune-SA.

Ivolumu yemibala, ubungqingqwa kunye nebala lokukhawuleza kwe-rabble iphantsi kwe-SA; Ukushicilelwa kwe-hecmc kuziva, umbala wokuzimela utyanile kwirabha kuyafana ne-SA;

Umyinge wencamathisela uphakame ngakumbi kune-SA, kodwa umbala obonakalayo webala kunye nokugcina uzinzo lwe-hecmc bephantsi kwe-SA.

Iingcebiso ezi-5.2

Ukusuka kwisiphumo seSicelo se-5.1 Seler Sethel Passinas unokufunyanwa, i-Selese I-Ether Paste inokusetyenziswa

I-Dye Printa i-pastes, ngakumbi i-anionic selese tasile. Ngenxa yokuqaliswa kwe-Cydrophilic yeQela le-Hydbophilic yeQela

Ukuphinda kwenziwe iQela le-Hydroxyl eziphambili kwi-ring, kunye nentlawulo engeyiyo emva kwexeshana elinye, unokukhuthaza ukudaya kwe-fibers nge-DYES. Nangona kunjalo, iyonke,

Isiphumo seSicelo se-Ether Plate Trinta i-EATER AYIHLE KAKHULU, NGU-BOCATE ngenxa yenqanaba lokufakelwa okanye ukufakelwa kwe-molar selet.

Ngenxa yesidanga esisezantsi sokufakelwa, ukulungiswa kwe-seluplose esuka kwiDilesi ePhakamileyo okanye isidanga esiPhakamileyo seMolar esifuna ukuqhubeka nokufunda.
