Intshayelelo yeMveliso ye-CMC yokuNcama ngokuSebenzayo

1. I-Sodium Carboxymethyl Cellulose
I-Reactive printing paste yi-derivative ene-ether structure efunyenwe ngokuguqulwa kweekhemikhali zeselulosi yendalo.Yiglue e-soluble yamanzi enokuthi inyibilike emanzini abandayo kunye namanzi ashushu.Isisombululo saso samanzi sinemisebenzi yokudibanisa, ukuqina, ukusabalalisa, ukumisa kunye nokuzinzisa.

I-Reactive printing paste yimveliso ye-sodium carboxymethyl cellulose eneqondo eliphezulu le-etherification.Inkqubo ekhethekileyo yenza iqela layo eliphambili le-hydroxyl litshintshwe ngokupheleleyo, ukuze kuthintelwe ukusabela ngeedayi ezisebenzayo.

Njengoko i-thickener ye-paste yokuprinta, intlama yokushicilela esebenzayo inokuzinzisa i-viscosity, iphucule i-fluidity ye-paste, iphucule isakhono se-hydrophilic yedayi, yenza iyunifomu yokudaya kunye nokunciphisa umehluko wombala;ngelo xesha, kwinkqubo yokuhlamba emva kokuprinta kunye nokudaya, izinga lokuhlamba liphezulu, Ilaphu liziva lithambile kwi-touch.

2. Ukuthelekiswa kweempawu ze-reactive printing paste kunye ne-sodium alginate
2.1 Ireyithi yokuncamathelisa

Xa kuthelekiswa ne-alginate ye-sodium, i-reactive paste yokuprinta ine-viscosity ephezulu, nokuba isetyenziswe yodwa okanye idibene nezinye i-thickeners, inokunciphisa ngokufanelekileyo iindleko ze-paste;ngokuqhelekileyo, i-paste yoshicilelo esebenzayo Idosi yi-60-65% kuphela ye-sodium alginate.

2.2 Imveliso yombala kunye nokuziva

Imveliso yombala wencama yokuprinta elungiselelwe intlama yoshicilelo esebenzayo njenge-thickener ilingana nesodium alginate, kwaye ilaphu livakala lithambile emva kokuba lide, elilingana naleyo yeemveliso zokuncamathisela zesodium alginate.

2.3 Ncamathelisa uzinzo

I-sodium alginate yi-colloid yendalo, enokunyamezelwa kakubi kwi-microorganisms, ixesha elifutshane lokugcina ixesha lokunamathisela umbala, kwaye kulula ukuyonakalisa.Uzinzo lweemveliso eziqhelekileyo ze-sodium carboxymethyl cellulose ziphezulu kakhulu kunesodium alginate.Iimveliso zokuncamathisela ezisebenzayo ziphuculwe yinkqubo ekhethekileyo, kwaye ukuxhathisa kwabo kwe-electrolyte kungcono kunemveliso eqhelekileyo ye-sodium carboxymethyl cellulose.Ngexesha elifanayo, banokuhambelana kakuhle kunye neekhemikhali ezincedisayo kunye nedayi, kwaye akulula ukonakala kunye nokonakala ngexesha lokugcinwa.Ukuzinza kweekhemikhali kungcono kakhulu kune-sodium alginate.

2.4 I-Rheology (eyongezelelweyo)

Zombini i-alginate ye-sodium kunye ne-CMC ziyi-pseudoplastic fluids, kodwa i-alginate ye-sodium ine-viscosity ephantsi yesakhiwo kunye nexabiso eliphezulu le-PVI, ngoko ke ayifanelekanga ukuprintwa kwesikrini esijikelezayo (esicaba), ngakumbi ukuprintwa kwesikrini se-mesh ephezulu;iimveliso zokuncamathelisa ezisebenzayo zinokwakheka okuphezulu kwe-viscosity, ixabiso le-PVI limalunga ne-0.5, kulula ukuprinta iipateni ezicacileyo kunye nemigca.Ukudityaniswa kwe-alginate ye-sodium kunye ne-paste yokushicilela esebenzayo kunokuhlangabezana neemfuno ze-rheological zokuncamathisela
