1. I-Sodium Carboxymethyl Cellulose
Okunamathiselwe kokuphrinta okusebenzayo kuwukuphuma okunesakhiwo se-ether esitholakala ngokuguqulwa kwamakhemikhali kwe-cellulose yemvelo.Kuyiglue encibilikayo emanzini engancibilika emanzini abandayo nasemanzini ashisayo.Isixazululo saso esinamanzi sinemisebenzi yokuhlanganisa, ukuqina, ukuhlakaza, ukumisa nokusimamisa.
I-Reactive printing paste iwumkhiqizo we-sodium carboxymethyl cellulose enezinga eliphezulu le-etherification.Inqubo ekhethekile yenza iqembu layo eliyinhloko le-hydroxyl lithathelwe indawo ngokuphelele, ukuze kugwenywe ukusabela ngodayi abasebenzayo.
Njengokuqina kokunamathisela kokuphrinta, ukunamathisela kokuphrinta okusebenzayo kungazinzisa i-viscosity, kuthuthukise uketshezi lokunamathisela, kuthuthukise ikhono le-hydrophilic likadayi, kwenze umfaniswano wokudaya futhi kunciphise umehluko wombala;ngesikhathi esifanayo, ekuhlanzeni inqubo emva kokuphrinta nokudaya, izinga lokugeza liphakeme, Indwangu izwa ithambile lapho ithinta.
2. Ukuqhathaniswa kwezici zokunamathisela okuphrinta okusebenzayo kanye ne-sodium alginate
2.1 Izinga lokunamathisela
Uma kuqhathaniswa ne-alginate ye-sodium, ukunamathisela okuphrinta okusebenzayo kune-viscosity ephakeme, kungakhathaliseki ukuthi isetshenziswe yodwa noma ihlanganiswe namanye ama-thickeners, inganciphisa ngempumelelo izindleko zokunamathisela;ngokuvamile, ukunamathisela okuphrinta okusebenzayo Umthamo ungama-60-65% kuphela we-sodium alginate.
2.2 Umphumela wombala nomuzwa
Umkhiqizo wombala wokunamathisela okuphrintayo olungiselelwe ngokunamathisela okuphrinta okusebenzayo njengokujiya kulingana naleyo ye-sodium alginate, futhi indwangu izwakala ithambile ngemva kokukhishwa, okulingana naleyo yemikhiqizo yokunamathisela ye-sodium alginate.
2.3 Namathisela ukuzinza
I-sodium alginate iyi-colloid yemvelo, engabekezeleli kahle amagciwane, isikhathi sokugcina esifushane sokunamathisela umbala, futhi kulula ukuyonakalisa.Ukuzinza kwemikhiqizo ejwayelekile ye-sodium carboxymethyl cellulose kuphakeme kakhulu kunaleyo ye-sodium alginate.Imikhiqizo yokunamathisela yokuphrinta esebenzayo ithuthukiswe ngenqubo ekhethekile, futhi ukumelana kwabo kwe-electrolyte kungcono kunemikhiqizo ejwayelekile ye-sodium carboxymethyl cellulose.Ngesikhathi esifanayo, banokuhambisana okuhle nama-axiliary amakhemikhali namadayi, futhi akulula ukonakala nokuwohloka ngesikhathi sokugcina.Ukuzinza kwamakhemikhali kungcono kakhulu kune-sodium alginate.
2.4 I-Rheology (ehambisanayo)
Kokubili i-alginate ye-sodium ne-CMC ama-pseudoplastic fluids, kodwa i-sodium alginate ine-viscosity yesakhiwo ephansi kanye nenani eliphakeme le-PVI, ngakho-ke ayifanele ukuphrinta kwesikrini esiyindilinga (flat), ikakhulukazi ukuphrinta kwesikrini se-high-mesh;imikhiqizo yokunamathisela yokuphrinta esebenzayo ine-viscosity ephezulu yesakhiwo, inani le-PVI lilinganiselwa ku-0.5, kulula ukuphrinta amaphethini acacile nemigqa.Inhlanganisela ye-sodium alginate kanye nokunamathisela okuphrinta okusebenzayo kungahlangabezana nezidingo ze-rheological zokunamathisela kokuphrinta
