1. Intshayelelo
I-Hydroxyethyl cellulose (HEC) yipolymer eguquguqukayo evela kwiselulosi, esetyenziswa kakhulu kumashishini ahlukeneyo ngenxa yeempawu zayo ezibalaseleyo zerheological, amandla okugcina amanzi, kunye nokuhambelana nezinye izinto.Kwindawo yokwenziwa kwe-inki, i-HEC isebenza njengenxalenye ebalulekileyo, inika iimpawu ezinqwenelekayo ezifana nolawulo lwe-viscosity, ukuzinza, kunye nokubambelela.
2.Ukuqonda i-HEC kwii-Ink Formulations
Kwimiqulu ye-inki, i-HEC isebenza njenge-ejenti yokuqina, iphucula i-viscosity ukufezekisa iimpawu zokuhamba kakuhle.Ubume bayo be-hydrophilic bubangela ukuba kugcinwe ngokufanelekileyo amanzi ngaphakathi kwe-inki matrix, ukuthintela ukomisa kwangaphambi kwexesha kunye nokugcina ukuhambelana ngexesha leenkqubo zokushicilela.Ngaphezu koko, i-HEC ibonisa ukuziphatha kokucheba, oku kuthetha ukuba kunciphisa i-viscosity phantsi koxinzelelo lwe-chear, iququzelela ukusetyenziswa kakuhle kwii-substrates ezahlukeneyo.
3.Iinzuzo zokuBandakanywa kwe-HEC kwii-Inks
Ulawulo lweViscosity: I-HEC inikezela ngolawulo oluchanekileyo kwi-viscosity ye-inki, ibalulekile ekuphumezeni umgangatho ofunekayo woshicilelo kunye nokusebenza ngeendlela ezahlukeneyo zoshicilelo.
Ukuzinza okuphuculweyo: Ngokwenza i-matrix ezinzileyo, i-HEC ivimbela ukuchithwa kunye nokuhlukana kwesigaba, ukuqinisekisa ukuhanjiswa kwe-inki efanayo kunye nokuzinza kwexesha elide.
I-Adhesion ephuculweyo: Iimpawu zokubambelela ze-HEC zikhuthaza ukunamathela okungcono phakathi kwe-inki kunye ne-substrate, okukhokelela ekuphuculweni kokuprinta kunye nokuchasana nokukhwabanisa.
Ukugcinwa kwamanzi: Ukugcina amanzi kwe-HEC amandla okugcina amanzi anciphisa ukuguquka kwamanzi ngexesha lokushicilela, ukunciphisa ixesha lokumisa i-inki kunye nokuthintela ukuvala umlomo kwiiprinta ze-inkjet.
Ukuhambelana: I-HEC iyahambelana noluhlu olubanzi lwezongezo ze-inki kunye nee-pigments, ezivumela ukwakheka kwee-inki eziguquguqukayo ezilungiselelwe iimfuno ezithile zokushicilela.
UBungane beNdalo: Njengepolymer esekelwe kwi-bio-based, i-HEC inegalelo ekuzinzeni kokwenziwa kwe-inki, ukulungelelanisa kunye nezenzo ze-eco-friendly kushishino lokushicilela.
4.Iingqwalasela eziSebenzayo kwiSicelo seHEC
Ugxininiso oluLungileyo: Uxinaniso lwe-HEC kwiifom ze-inki kufuneka luphuculwe ngononophelo ukufezekisa i-viscosity efunwayo ngaphandle kokuphazamisa ezinye iipropati ze-inki.
Uvavanyo lokuhambelana: Ngaphambi kokuveliswa kwemveliso enkulu, uvavanyo lokuhambelana namanye amacandelo e-inki kunye ne-substrates kubalulekile ukuqinisekisa uzinzo kunye nokusebenza.
Ulawulo lobungakanani besuntswana: Ukuhanjiswa kobungakanani besuntswana le-HEC kufuneka ilawulwe ukunqanda ukuvaleka kwezixhobo zoshicilelo, ngakumbi kwiinkqubo zoshicilelo lwe-inkjet.
Iimeko zokuGcina: Iimeko ezifanelekileyo zokugcina, kubandakanywa nolawulo lobushushu kunye nokufuma, zibalulekile ekugcineni imfezeko yokwenziwa kwe-inki esekwe kwi-HEC kunye nokwandisa ixesha leshelufu.
Ukuthotyelwa kwemiGaqo: Ukuthotyelwa kwemigangatho yolawulo, efana naleyo iphathelele kukhuseleko, impilo, kunye nefuthe lokusingqongileyo, kufuneka kuqinisekiswe xa kusetyenziswa i-HEC kwimixube ye-inki.
5.I-Case Studies kunye nezicelo
Ukuprintwa kweFlexographic: Ii-inks ezisekelwe kwi-HEC zisetyenziswa ngokuqhelekileyo ukuprintwa kwe-flexographic kwizinto zokupakisha, ezinikezela ngokuprinta okugqwesileyo, ukunamathela, kunye nokuhambelana kombala.
Ushicilelo olulukiweyo: Kushicilelo olulukiweyo, i-HEC inika ulawulo lwe-viscosity kunye nokukhawuleza ukuhlamba kwii-inki, ukuqinisekisa ukuprintwa okunamandla kunye nokuqina kwiilaphu ezahlukeneyo.
Ukuprintwa kwe-Inkjet: I-HEC isebenza njengecandelo eliphambili ekuqulunqweni kwe-inkjet, ukubonelela ngokuzinza kwe-viscosity kunye nokuthintela ukuvala umbhobho, ngokukodwa kwizicelo zokushicilela ngokukhawuleza.
Ushicilelo lweGravure: Iinki ezisekwe kwi-HEC kushicilelo lwegravure zibonisa iipropathi ezihamba phambili ezihamba kakuhle kunye nokuncamathela, okukhokelela kushicilelo olukumgangatho ophezulu kwiisubstrates ezahlukeneyo ezifana nephepha, iplastiki kunye nentsimbi.
I-Hydroxyethyl cellulose (HEC) idlala indima ebaluleke kakhulu ekuqulunqweni kwe-inki kuzo zonke iintlobo zezicelo zoshicilelo, ibonelela ngebhalansi yolawulo lwe-viscosity, uzinzo, kunye nokuncamathela.Ukuguquguquka kwayo, kunye nokusebenzelana kwendalo, kuyenza ibe lukhetho olukhethwayo kubavelisi be-inki abafuna ukunyusa umgangatho woshicilelo kunye nokusebenza ngelixa bebambelela kwiinkqubo ezizinzileyo.Ngokuqonda iindlela kunye neenzuzo ze-HEC kuqulunqo lwe-inki, abashicileli banokusebenzisa amandla abo ukuphumeza iziphumo eziphezulu kwiinzame zabo zokushicilela.
