Ukusetyenziswa kweHydroxypropyl Methyl CellulosekuShicilelo lwe-Ink
I-inki yenziwe ngee-pigments, izibophelelo kunye nee-agent ezincedisayo (i-hydroxypropyl methylcellulose), ezixutywe kwaye ziqengqeleke.
Ulungele uku-inki. Umbala, umzimba (ngokuqhelekileyo iimpawu rheological inki ezifana ukungaguquguquki obhityileyo kunye fluidity kuthiwa umzimba inki) kunye nokumisa ukusebenza zezona mpawu zintathu zibalulekileyo inki.
Instant hydroxypropyl methylcellulose yoshicilelo lwe-inki ngumgubo ongenavumba, ongenancasa, ongenatyhefu.
Iyadumba ibe yicolloidal ecacileyo okanye enamafu kancinane kumanzi abandayo. Ineempawu zokuqina, ukudibanisa, ukusabalalisa, i-emulsification, ifilimu-ifom, ukumiswa, i-adsorption, i-gelation, umsebenzi we-surface, ukugcinwa kwamanzi kunye ne-colloid yokukhusela. idlala indima ebalulekileyo kwi.

I-Hydroxypropyl methylcellulose ine-viscosities ezintathu ze-100,000, i-150,000, kunye ne-200,000. I-viscosity luphawu lokuhamba kolwelo lwe-inki.
Isalathisi sobungakanani bokuchasana (okanye ukungqubuzana kwangaphakathi) ukunyakaza. Kwinkqubo yoshicilelo lwe-offset, i-viscosity ethile iyimfuneko ukugcina ukuhanjiswa kwe-inki ngokuqhelekileyo.
Yimeko ephambili yokuhanjiswa kunye nokudluliselwa, kwaye kuyimeko ebalulekileyo yokumisela ukukhawuleza, ukucaca kunye ne-gloss of imprinting. I-viscosity ye-inki
Ukuba kukhulu kakhulu, kuya kuba nzima ukudlulisa kunye nokudlulisa, ukwenzela ukuba inani le-inki kwi-layout liya kuba linganele, okubangelwa ubuze bemizobo kunye nokubhaliweyo ukwenza ipateni. Ngokufanayo, i-viscosity
Ukuba likhulu kakhulu, kulula kwakhona ukubangela ukuba iphepha lihlanjululwe kwaye libe ngumgubo, okanye kubangele ukukhutshwa kwephepha eliprintiweyo. Kodwa ukuba i-viscosity incinci kakhulu, kulula ukuyivelisa
Ukudada kunye nokungcola, kuya kubangela i-inki emulsification kwiimeko ezinzima, ukuba ayikwazi ukugcina ukuhanjiswa okuqhelekileyo kunye nokudluliselwa, kwaye ngokuthe ngcembe kwi-inki.
Iinqununu ze-pigment ziqokelela kwii-roller, iiplate zokuprinta kunye neengubo, kwaye xa ukuqokelela kufikelela kwinqanaba elithile, kuya kubangela ukuhlambalaza.

I-Hydroxypropyl methyl celluloseinonamathela kakuhle, ukuphepha ukuncamathela kweinki ngexesha lenkqubo yoshicilelo
Ayihambelani nokusebenza kunye neemeko zoshicilelo lwe-substrate, okukhokelela kumgubo wephepha, i-lint, i-inki embi kakhulu, ukuprinta.
Ukungaphumeleli kokushicilela okufana neepleyiti ezingcolileyo.

I-Hydroxypropyl methylcellulose ine-thixotropy elungileyo, ithintela i-thixotropy ye-inki ngexesha lenkqubo yokushicilela.
Ukungaphumeleli kokushicilela okufana "nokuhamba kakubi kwe-inki", ukuhanjiswa kwe-inki engalinganiyo, kunye nokwandiswa okunzulu kwamachaphaza okubangelwa yimbi.

IHydroxypropyl methylcellulose inoncamathelo ephezulu kakhulu, kwinkqubo yoshicilelo lwe-offset, amandla e-inki e-inki awathanga ngqo kuphela.
Inxulumene nesiphumo soshicilelo kunye nomgangatho wemveliso eprintiweyo, kwaye inxulumene kakhulu nesixa se-inki kwindawo nganye. Ukuba ukhetha
Ukusebenzisa i-inki ezomeleleyo zokuthamba kuya kusebenzisa i-inki encinci kune-inki enamandla abuthathaka, kwaye kunokufumaneka iziphumo ezilungileyo zokuprinta.

IHydroxypropyl methylcelluloseinobumanzi obugqwesileyo, i-inki eyi-fluidity efanelekileyo, kunye nomgangatho kumthombo we-inki
Inobuchule bokuyinki obulungileyo kunye nobuchule obufanelekileyo bokuyinki; ukudluliselwa kunye nokudluliselwa phakathi kweerola ze-inki okanye phakathi kwepleyiti yokushicilela kunye nengubo nayo ilungile;
Umaleko we-inki ufana; ifilim ye-inki eshicilelweyo ithe tyaba kwaye igudileyo. Ukuba i-fluidity incinci kakhulu, kulula ukubangela ukukhutshwa kwe-inki embi; ukusabalalisa okungafaniyo koluhlu lwe-inki, njl.
isenzeko, umphezulu wefilimu ye-inki eprintiweyo nawo uya kuvela amaza. Xa i-fluidity inkulu kakhulu, umaleko we-inki obhityileyo kulula ukubangela ukwanda kwamachaphaza, ukuprinta
Umbala awunamandla. Indlela yemitha yokuhamba isetyenziswa ngokuqhelekileyo.
