Sithini isicelo se-hydroxythyl seluplose (hec) kwi-inki?

1. Ushwankathelo lwe-hydroxyythl seluplose (hec)

I-HydroxyEtheetheetheetheetheethl seluplose (hec) yi-polymer engeyiyo i-ionic, i-poly-allmer esuswe kwi-sellulose. Yaziwa ngokuba yi-ficketing, ukwenza ifilimu, kunye nokuzinzisa iipropathi, zenza ukuba ibe yinto eyongeziweyo kwimizi-mveliso eyahlukeneyo, kubandakanya i-pharmcoceuticals, cosmetics, ulwakhiwo. Kwishishini le-inki, i-HEC isebenza ngemisebenzi emininzi ebalulekileyo eyandisa intsebenzo kunye nomgangatho we-inki.

2. Indima ye-hec kwi-inki yokuqulunqwa

2.1 Ukulungiswa kwe-RheOOOLOG
Enye yezicelo eziphambili ze-hec kwi-inki injenge-suheology modifier. I-RUOOOLOF ibhekisele kwimpawu yokuhamba kunye nokulahleka kwe-inki, ebaluleke kakhulu kwizicelo ezinje ngokuprinta, ukuqeqesha nokubhala. I-HEC inefuthe kwi-viscosity kunye nokuhamba kweentyatyambo ze-inks, ukuhambisa izibonelelo ezininzi:

Ulawulo lwe-Viscosity: hec lunokuhlengahlengisa i-viscofity yefomu ye-inki ukufezekisa ukungangqinelani okufunekayo. Oku kubalulekile kwiindidi ezahlukeneyo ze-inks, ezinjengezo zisetyenziswa kwi-screen yokuprinta, i-flexusgraphy, kunye nokuprinta, apho iiprofayili ze-viscofity ezifunwayo ziyintsebenzo efanelekileyo.
Ukuhambahamba kokuhamba: Ngokulungisa iipropathi ze-riheoology, i-HEC iyanceda ukulawula indlela yokuziphatha ye-Inki ye-Inki, iqinisekisa ukuhamba okuhle phantsi kweemeko ezahlukeneyo ze-Shear. Oku kubaluleke kakhulu kwizicelo ezinjengokuprinta i-inkJet, apho i-inki kufuneka ihambe rhoqo nge-nozzles ezilungileyo ngaphandle kokuvalwa.

2.2 Ukuzinza kunye nokunqunyanyiswa
I-hec isebenza njengesiqhelo kunye ne-arhente yokumisa kwi-Inki. Lo msebenzi ubalulekile ekugcineni i-homogeneity ye-ITK, kunye nokuqinisekisa ukusebenza okungaguqukiyo:

Ukunqunyanyiswa kwe-pigment: Kwi-inks ye-pigrimes, i-HEC iyanceda ukugcina imigca ihlukumezile ngokupheleleyo kuyo yonke loo nto, ukuthintela i-sedation. Oku kukhokelela ekubeni kungqineke kombala okhethekileyo kunye nomgangatho wokuprinta.
Uzinzo olu-onulsion: kwii-inks ezizinzo ezizinzo, ezinjengezo zisetyenziswa kwi-lithography, i-HEC iphucula uzinzo lwe-emulsion, ukuthintela ukwahlukana kwinqanaba kunye nokuqinisekisa isicelo esifanayo.

2.3 Ukuqulunqwa kwefilimu
I-HEC inegalelo kwiipropathi zokwenza ifilimu ze-interks. Ifilimu elizinzileyo nengalinganiyo ibalulekile kwisithuba sezinto eziprintiweyo:

Ukuthetha ngokukhululekileyo: Xa kusetyenziswa amantshontsho, i-HEC inceda ekwenzeni ifilimu engaguqukiyo enamathele kakuhle, ukuphucula umgangatho womaleko oshicilelweyo.
Ukukhuselwa komphezulu

2.4 Ukugcinwa kwamanzi
Ukwazi kukaHec ukugcina amanzi edlala indima ebalulekileyo ekwenzeni i-inki esekwe emanzini:

Ulawulo olomileyo: I-HEC iyanceda ukulawula umyinge wowomileyo wee-inks. Oku kuluncedo ngakumbi kwiinkqubo zokushicilela apho kufuna ukwenziwa kancinci kancinci ukuphepha imiba efana nokuvala okanye umgangatho ongalunganga.
Ukusebenza: Ngokugcina amanzi, i-HEC iqinisekisa ukuba i-inki igcina ukungangqinelani okunokwenzeka kwixesha elininzi, elibalulekileyo kwizicelo ezinjengomshicileli we-Screen kunye neFlexography.

2.5 ukuhambelana namanye amacandelo
I-HEC iyahambelana noluhlu olubanzi lwamacandelo i-inki, kubandakanya nee-pigments, iibhothi, kunye nezinyibilikisiweyo:

Ukuqulunqwa kokuguquguquka: Uhlobo lwe-Ionic lwe-io-i-IOC luvumela ukuba isebenze kakuhle ngee -ovestives ezahlukeneyo kunye neemodyuli ezisetyenziswa kwimisebenzi ye-inki, ukubonelela ngeefomula eziguquguqukayo ukufezekisa iimpawu zentsebenzo.
Ukungasebenzi kunye nokuzinza: I-Hec inyibilikiswa kumanzi abandayo ashushu, kwaye ihlala ihleli ngaphezulu kwe-PH i-PH, isenza ilungele iinkqubo ezahlukeneyo ze-inki.

3. Izicelo ezithile kwiindidi ezahlukeneyo ze-inki

3.1 I-inki yokuprinta
Ukuprintwa kwesikrini, apho i-inicks kufuneka ilingane nokuthintela ukusasazeka kwi-mesh, i-HEC isetyenziselwa ukulawula i-viscofity kunye nokuphucula inkcazo yoshicilelo. Iqinisekisa ukuba i-inki inomngqinisiso olungileyo ukubambelela kwiscreen kunye nokudlulisela ngokuchanekileyo kwi-subsest.

I-3.2 i-tlexusgraphic kunye ne-inki ye-inki
Ngee-inki ze-futographic kunye ne-inki ethatyathwayo, efuna iiprofayili ze-viscofity ezithile zokudluliselwa kunye nokunamathela, kuyanceda ekufezekiseni iimpawu ezichanekileyo zokuhamba. Iqinisekisa ukuba i-Inks yenza ukuba ibe mncinci, nokubambeka kwiiplate zokushicilela kunye nokushicilelwa kamva kwikhubalo.

3.3 I-inkit inks
Kwi-inki ye-inkit, ngakumbi ifomumu esekwe emanzini, i-HEC ekusebenzeni i-viscofity ukuqinisekisa ukuthambisa ijeyithi kunye nokuthintela ukudalwa kwe-nozzle. Ikwanceda ekugcineni ukumiswa kwe-pigment, kubaluleke kakhulu ekuveliseni umgangatho ophezulu, onomdla.

3.4 I-Inks yokuthoba
Ekuhambeni kweenkokhetha, njengabasetyenziselwa ukugqiba kwe-glossy okanye iileyithi zokukhusela, i-HEC ifaka ifilimu yokusekwa kwefilimu egudileyo, efanayo. Kuyanceda ekufezekiseni ubuhle obufunwayo nobume bokudibana, kubandakanywa nokubonisa, ukuqina, kunye nokuxhathisa izinto zangaphandle.

4. Izibonelelo zokusebenzisa i-hec kwi-inki

Ukuphuculwa komgangatho wokuprinta: Ngokubonelela nge-vigrafity kunye nokumiswa kwezinto ezithile, i-HCC iphucula umgangatho wokuprinta ngokubanzi, kubandakanya ukuchaneka kombala kunye nokubukhali.
Ukusebenza okusebenzayo: Ukugcinwa kwamanzi kunye neepropathi zotshintsho lwe-hec zegalelo kwiinkqubo ezifanelekileyo zokuprinta, ukunciphisa ixesha lokuphumla okubangelwa yimicimbi efana ne-nozzle i-nozzle i-nozzle.
Ukungaguquguquki

5. Ukuqwalaselwa kokusiNgqongileyo kunye nokhuseleko

I-HEC isuselwa kwisellumse, isibonelelo esihlaziyiweyo, sisenza ukuba khetha ubunobuhlobo obujolise kwindalo esingqongileyo xa kuthelekiswa ne-polymers yokwenziwa. I-biodegradiation yayo yongeza kwimithombo yayo yokusingqongileyo. Ukongeza, i-HEC ithathelwa ingqalelo ukuba ikhuseleke kwi-Inks, ibeka imingcipheko encinci kwimpilo nokhuseleko xa ilawulwa ngokufanelekileyo.

I-HydroxyEtheetheetheetheetheetheethy (Hec) ibaluleke kakhulu kwi-Inki yanamhlanje ye-IK, ihambisa uluhlu lwezibonelelo zolawulo lwe-viscofity kunye nokuzinza kwefilimu kunye nokugcinwa kwamanzi. Ukusetyenziswa kwendlela yayo kunye nokuhambelana neenkqubo ezahlukeneyo ze-IK kwenza ukuba ibe yinto ebaluleke kakhulu ekufezekiseni intsebenzo ekumgangatho ophezulu, engaguqukiyo nefanelekileyo. Njengoko ishishini le-inki liyaqhubeka ukuvela, indima yehek inokuthi yandise ngakumbi, iqhutywa kukuziqhelanisa nokuziqhelanisa nokusebenza.
