Kushandiswa kweHydroxypropyl Methyl CelluloseKudhinda neInk
Inki iyi inoumbwa ne pigments, binders uye assistant agents (hydroxypropyl methylcellulose), izvo zvinosanganiswa uye zvinokungurutswa.
Inki yakagadzirira kushandiswa. Ruvara, muviri (kazhinji hunhu hwe rheological hweinki hwakadai sekusimba kwakatetepa uye kuyerera kwemvura zvinonzi muviri weinki) uye mashandiro ekuomesa ndiwo hunhu hutatu hwakakosha hweinki.
Instant hydroxypropyl methylcellulose yekudhinda inki ipfu chena isina hwema, isina kuravira, isina chepfu.
Inokura kuita colloidal solution yakajeka kana ine makore mashoma mumvura inotonhora. Ine hunhu hwekukora, kubatana, kupararira, emulsification, kugadzira firimu, kumisa, kunyungudutsa, gelation, kushanda pamusoro, kuchengetedza mvura uye colloidal inodzivirira. Inoita basa rakakosha mu.

Hydroxypropyl methylcellulose ine viscosities nhatu dze100,000, 150,000, uye 200,000. Viscosity ndiyo hunhu hwekuyerera kwemvura yeinki.
Chiratidzo chehuwandu hwekusagona kufamba (kana kukweshana kwemukati) kwechinhu. Mukudhinda kwe offset, kupenya kwakati kwakakosha kuti inki irambe yakajairwa.
Ndiyo chinhu chikuru chinodiwa pakutumira nekutumira, uye chinhu chakakoshawo pakuona kuti inki iri kupenya, kujeka uye kupenya kwekudhinda.
Kana yakakura zvakanyanya, zvichave zvakaoma kutamisa nekutamisa, zvekuti huwandu hweinki pahurongwa hahuzokwani, zvichikonzera kusaonekwa kwemifananidzo nemagwaro kuti zvigadzire patani. Saizvozvowo, viscosity
Kana yakakura zvakanyanya, zviri nyorewo kuti bepa riite fluffy uye upfu, kana kuti riite kuti bepa rakadhindwa ribve. Asi kana viscosity iri diki, zviri nyore kugadzira.
Inenge yakasviba uye ichiyangarara, inokonzera kusanganiswa kweinki muzviitiko zvakakomba, kana ikasakwanisa kuchengetedza kutumirwa kwakajairika uye kutamiswa, uye zvishoma nezvishoma muinki.
Zvidimbu zveruvara rweganda zvinoungana pamaroller, maplate ekudhinda nemagumbeze, uye kana kuungana kwacho kwasvika padanho rakati, zvinokonzeresa kusviba.

Hydroxypropyl methyl celluloseine kunamira kwakanaka, ichidzivirira kunamira kweinki panguva yekudhinda
Hazvienderane nekushanda uye mamiriro ekudhindwa kwesubstrate, zvichikonzera upfu hwepepa, lint, inki isina kunaka yekudhinda, uye kudhinda
Kukundikana kwekudhinda kwakadai semaplate akasviba.
3
Hydroxypropyl methylcellulose ine thixotropy yakanaka, ichidzivirira thixotropy yeinki panguva yekudhinda.
Kukundikana kudhindwa kwakadai se "kushaikwa kweinki kwakashata", kutamiswa kweinki kusina kuenzana, uye kukura kwakanyanya kwemadotsi kunokonzerwa nekushaikwa kwayo.

Hydroxypropyl methylcellulose ine kunamatira kwakanyanya, panguva yekudhinda kwe offset, simba rekupenda kweinki harisi chete rakananga.
Zvine chekuita nemhedzisiro yekudhinda uye mhando yechigadzirwa chakadhindwa, uye zvine chekuitawo nehuwandu hweinki pachikamu chimwe nechimwe. Kana ukasarudza
Kushandisa inki dzine simba guru rekudhirowa kuchadya inki shoma pane inki dzine simba shoma rekudhirowa, uye mhedzisiro yakanaka yekudhirowa inogona kuwanikwa.

Hydroxypropyl methylcelluloseine inki inoyerera zvakanaka, inki inoyerera zvakanaka, uye inoyera muchitubu cheinki
Ine kugona kwakanaka kwekuisa inki uye kugona kwakanaka kwekuisa inki; kutamisa nekufambisa pakati pemaroller einki kana pakati peplate yekudhinda negumbeze zvakanakawo;
Rutivi rweinki rwakafanana; firimu reinki rakadhindwa rakati sandara uye rakatsetseka. Kana kuyerera kwaro kuri kudiki, zviri nyore kukonzera kuburitsa kweinki kusina kunaka; kupararira kusina kuenzana kwerutivi rweinki, nezvimwewo.
Chiitiko ichi, pamusoro pefirimu reinki rakadhindwa pachaonekwawo mafungu. Kana kuyerera kwacho kwakanyanya, jira reinki rakatetepa riri nyore kukonzera kuwedzera kwedotsi, richidhindwa.
Ruvara haruna kusimba. Nzira yekuyera kuyerera kwemvura ndiyo inonyanya kushandiswa.
