Ndeipi iyo application yehydroxyethyl cellulose (Hec) mu inki?

1. Kuongorora kwehydroxytHyl cellulose (hec)

HydroxytHyl Cellulose (Hec) is is is is is-ionic, yemvura-yakadzika-mvura polymer yakatorwa kubva ku cellulose. Izvo zvinozivikanwa nekukwira kwayo, uye kusimbisa zvivakwa, zvichiita kuti zvive zvinowedzera zvose mumaindasitiri akasiyana-siyana, kusanganisira mishonga yemishonga, cosmetics, kuvakwa, uye inki. Muindasitiri yeInk, hec inoshandira mabasa mazhinji akakosha anowedzera kuita uye kunaka kweiyo inki mafomu.

2. Basa reHec muINK kuumbwa

2.1 Rheology shanduko
Chimwe chezvinyorwa zvekutanga zvehec mune inks its se rheology modifier. Rheology ine chekuita neyekuyerera uye gadziriso maitiro e inki, izvo zvakakosha kune zvekushandisa sekudhinda, kufukidza, uye kunyora. Hec inofurira iyo visikopa uye kuyerera maitiro emenki, kupa zvinoverengeka zvakanaka:

Viscosity Control: Hec inogona kugadzirisa iyo visikopa yeiyo ink mafomu ekuzadzisa iyo inodiwa yekuenderana. Izvi zvakakosha kumhando dzakasiyana dzezvinyorwa, dzakadai sevaya vanoshandiswa kudhinda rekudhinda, FLEXOgraphy, uye kudhinda kwekunyepedzera, uko kwakanangana neVacosity profiles inodikanwa pakuita kwakakwana.
Kuyerera kwehunhu: nekugadzirisa zvivakwa zvakatsanangurwa, hec inobatsira kudzora maitiro aInk Izvi zvinonyanya kukosha mukushandisa senge inkjet kudhinda, uko iyo ink inofanirwa kuyerera nayo nguva dzose kuburikidza nemazwi akanaka asina kubhururuka.

2.2 stabilization uye kumiswa
Hec zviito sedhizimusi uye kumhanyisa mumiririri muInk mafomu. Iri basa rinotsoropodza kuchengetedza homogeneity ye inks, kudzivirira kugadzirisa, uye kuvimba nekusawirirana kuita:

Pigment kumiswa: mune yakafemerwa inks, hec inobatsira kuchengeta iyo pigments yakafukidzwa zvakazara muumbi, ichidzivirira. Izvi zvinoguma zvine ruvara runako uye kudhinda mhando.
EMULSION STability: Yenyaya inoitwa nemhungu, yakadai seiya inoshandiswa muLitegraphy, hec inowedzera kugadzikana kweiyo emulsion, kudzivirira kupatsanurwa kwepakati uye kuona yunifomu yekushandisa.

2.3 Film Formation
Hec inopa kune iyo firimu-inoumba zvivakwa zve inks. Iyo yakagadzikana uye yunifomu firimu yakakosha kuti isimbe uye kutaridzika kwezvakadhindwa:

Kubatanidza Uwandu: Kana kuiswa kune Sinterrates, hec inobatsira kuumba firimu rinowirirana iyo inoenderana zvakanaka, ichivandudza mhando yedura rakadhindwa.
Kudzivirirwa Kwemhosva: Kugona kwemufirimu-kuumba kunowedzerawo denderedzwa redare kune zvekudhinda, kuvandudza kupokana kwavo kune zvinhu zvebrasion uye zvakatipoteredza zvinhu.

2,4 Kuchengeta Kwemvura
Kugona kwaHec kuchengetedza mvura inoita basa rakakosha mukuita kwemvura-yakavakirwa mvura:

Kupukuta Control: Hec inobatsira kudzora maitiro ekuomesa emenki. Izvi zvinonyanya kubatsira pakudhinda maitiro uko kupedza zvishoma nezvishoma kunodiwa kuti udzivise nyaya dzakaita sekuvhara kana kusarongeka kudhinda mhando.
Kurova: Nekuchengetedza mvura, hec inovimbisa kuti ink inochengetedza mukana wekushanda kwenguva yakareba, izvo zvakakosha mukushandisa sekudhinda kwekudhinda uye flexography.

2.5 kuenderana nezvimwe zvinhu
Hec inoenderana neyakaenzana huwandu hweinki zvikamu, kusanganisira pigment, mabhasi, uye solims:

Kuumbika Kuchinjika: Iyo isiri-Ionic chimiro cheHEC inobvumira kuti ishandire zvakanaka neakasiyana siyana uye modifizi inoshandiswa muInk mafomu, inopa mafungire nekuchinjika kuti uwane hunhu hwekuita.
Solubility uye kugadzikana: Hec inonyudza mumvura inotonhora uye inotonhora uye inopisa, uye ichiramba yakagadzikana pamusoro penzvimbo yakafara p p

3. Chaizvoizvo zvikumbiro mumhando dzakasiyana dzeInk

3.1 Screen Kudhinda Inks
Mukudhinda screen, uko maInks anofanirwa kuve akakora anokwana kudzivirira kupararira kuburikidza nemesh, hec inoshandiswa kudzora viscosity uye kuvandudza kududzirwa kududzirwa. Iyo inovimbisa kuti iyo inki ine kodzero yekuzvishingisa yekuomerera pachiratidziro uye kuendesa chaizvo kune iyo substrate.

3.2 Flexographic uye Graver Inks
Kune flexographic uye majekiseni ekuratidzira, izvo zvinoda chaiyo viscosity profiles yekuendeswa kwakakodzera uye kuomerera, hec inobatsira mukuzadzisa maitiro ekuyerera. Iyo inovimbisa kuti iyo inks inoumba mutete, kunyange denderedzwa pamahwendefa ekudhinda uye akazotevera pane substrate.

3.3 Inkjet Inks
MuNKJET Inks, kunyanya maficha-yakavakirwa mvura, Hec AIDS mukudzora viscosity kuti ive nechokwadi chekutapira uye kudzivirira clogle clogging. Izvo zvakare zvinobatsira pakuramba kumiswa kwenguruve, kwakakosha kuti ubudise yakakwirira-mhando, inodhinda.

3.4 Kubatanidza Inks
MuCoating Inks, yakadai seiya inoshandiswa kune glossy inopedzisa kana kuchengetedza zviyero, hec inobatsira kuumbwa kweyakaomeswa, yunifomu firimu. Inobatsira kuwana iyo yaunoda esthetic uye inoshanda zvivakwa zvekuvhara, kusanganisira kusawirirana, kusimba, uye kuramba kune zvekunze zvinhu.

4. Zvakanakira kushandisa hec mune inks

Kuvandudzwa kweDhinda Mhando: Nekupa kusingaperi viscosity uye kusarudzika pigment kumiswa, hec inowedzera iyo yakadhindwa yemhando yekudhinda, inosanganisira kurongeka kwemavara uye kupinza.
Kubudirira kushanda: Kuchengetwa kwemvura uye rheology shanduko yehyopa yekubatsira kwekudhinda yekudhinda
Kuedza

5. Kukurukurirana uye nekuchengetedza kufunga

Hec inotorwa kubva ku cellulose, chishandiso chinovandudzwa, ichiita kuti isarudzo yemamiriro ekunze yakafananidzwa nemafungu echiSynthetic. Yayo biodegradability inowedzerawo kune izvo zvakanakira zvakaratidzwa. Pamusoro pezvo, hec inowanzoonekwa yakachengeteka kuti ishandiswe mune inks, inoshandisa njodzi diki kuhutano uye kuchengeteka patakagadziriswa nemazvo.

Hydroxethyl Cellulose (Hec) chikamu chakakosha muzvinhu zvemazuva ano zveIntimasi, vachipa mhando dzezvakanaka kubva kuViscosity kudzora uye kusimbisa kuumbwa kwefirimu uye kuchengetwa kwemvura. Kuwedzera kwayo uye kuwirirana neakasiyana-siyana Inki kunoita kuti ive inowedzera kuwana yekuzadzisa yakakwirira-mhando, inoenderana, uye inoshanda ink. Sezvo indasitiri yeInk ichiramba ichishanduka, basa rehekisi rinogona kuwedzera mberi, rinotungamirirwa nekushandurwa kwayo uye kushandira zvivakwa.
