Matambudziko Akajairika eUV Ink muKudhinda

Dambudziko 1: Dots uye scraper zvinoonekwa pane anilox roller mushure mekukwesha. Kana muchina wekudhinda uchimhanya nekumhanya kwakaderera, hazvisi nyore kuitika; kana muchina wacho uchimhanya nekumhanya kwazvo, zviri nyore kwazvo kuitika, uye nekukwira kwemashini kumhanya, kunowedzera kuoneka kwazviri, uye hapana mutemo wekutevera.

Solution:

1. Wedzera chiyero chakakodzera chedoro (kwete kupfuura 5%) kune inki, iyo inovandudza kushanda kweinki.

2. Kana dambudziko racho richikonzerwa nekushandisa plastiki scraper, inogona kugadziriswa nekutsiva scraper;

3. Sefa ingi, iyo inokonzerwa netsvina yakawandisa;

Kuzununguka kwechikwesha kunoita kuti chikweshe chiome. Nekusarudza zvinhu zvakaoma uye zvimedu zvakatetepa, mavara einki anogona kudziviswa, simba rekubatana pakati pe scraper uye mesh roller rinogona kuwedzerwa, kana kuti nheyo ye scraper kana chitubu chekumanikidza chebanga rekutsvaira chinogona kuchinjwa.

Mukupedzisa, kuomesa iyo scraper uye kutsiva iyo yekumanikidza chitubu kuchavandudza simba rekuita. Kana zvinhu zviviri kana kupfuura zvabatanidzwa, zvese zviri zviviri zvinosimbisa "kuchinjika." Vanhu vanowanzo taura pamusoro pekugona kudhinda, senge ingi, mbishi, nezvimwewo, asi hukama pakati pe scraper ne mesh roller yakakoshawo.

Dambudziko rechipiri: Vhara mesh, paste ndiro; Iyo ndiro inovhara huwandu hwakakura hweinki, uye madotsi anoiswa nyore nyore mumifananidzo, inozivikanwawo sekumisikidza inki.

Solution:

1. Tsiva anilox roller;

2. Dzora viscosity yeinki;

3. Kana nhamba yemitsara padhiramu iduku zvikuru kana nhamba yemitsara yekudhinda yakanyanya kuenzana, funga kugadzirisa ndiro;

4. Dzora nzvimbo yekugadzira: Kana kutonhora kuchipfuura 50 ° C, ndiro inowedzera ne 1-3%, kuoma kunoderera, uye kuderedzwa kwedonhwe kunoderera. Nekuda kwekuwedzera kwemadotsi, zviri nyore kukonzera network blockage. Iyo yakakwirira tembiricha, zvakanyanya kuoma kudzora.

Dambudziko rechitatu: Mapini, moiré, uye kudhinda kusina kunaka.

Solution:

Mechanical pinholes, iyo inki haibatanidzi zvachose pamusoro pebepa, kana viscosity yeinki haina kukwana, iyo inki layer yanyanya kutetepa, uye kupfeka hakuna kuenzana. Ita shuwa kusangana kwakazara pakati pezviviri, zvikasadaro, kana iyo inki viscosity iri pakati nepakati, inogona kuvandudzwa.

Kemikari pinholes, iyo inki haigone kunyorova zvachose pamusoro peiyo substrate, ichiwedzera zvinowedzera kugadzirisa;

Chikonzero chekugadzira ndiro ndechokuti mushonga haugezwe asi unosiiwa pamufananidzo wendiro. Chenesa mushonga.

Zvimwe zvinokanganisa inki zvinosanganisira:

Simbi ndiro kuoma: Kuoma kwesimbi ndiro kunowanzo 60-70 madhigirii. Kana iyo yakaoma yakanyanya kuderera, haigoni kudzorera zvachose maitiro ayo epakutanga.

Kudhinda nharaunda: Ine simba guru painki. Sezvo ambient tembiricha inokwira, iyo inki inopinda denaturation uye solvent volatilization, izvo zvakaoma kudzora. Iyo tembiricha yeplate ichakwirawo, uye ndiro inozowedzera, kupfava, uye nekuremara, kunyanya panguva yekubvaruka. Zvinotonyanya kukosha, deformation yemadots yakanyanya kuoma kupfuura chero imwe graphic uye chinyorwa chikamu, haigone kudzorwa, uye yemanyepo yekudhinda mwero mushure mekudhinda zvakare inoderedzwa zvinoenderana.

Kuwedzera ingi chena kuingi kuchakanganisa kuomeswa kweinki nekuti chiedza chekufambisa chakavharwa. Panguva ino, kuwedzera kwekuwedzera hakushande, uye inki itsva inoda kuchinjwa kugadzirisa dambudziko. Nokudaro, zvinokurudzirwa kuedza kusawedzera zvakawanda zvinowedzera kune inki. Kuwedzera zvinowedzera zvinogona kugadzirisa mamwe matambudziko anowanikwa mukudhinda, asi kana zvikasadzorwa zvakanaka, mamwe matambudziko anogona kuitika. Inks-based inks inoshanduka nekukurumidza kana zvinowedzera zvinowedzera, uye kukurumidza kubvisa kunokurumidza zvakare. UV ingi dzakasiyana. Kuti uve nechokwadi chekudhinda mhando, zviri nani kuti usawedzera zvakawanda zvinowedzera.

Flexographic inki ine painogumira, uye zvakaoma kuwana mhedzisiro yakafanana nedzimwe nzira dzekudhinda maererano nemuvara, saturation, nezvimwe.

Solution:

Mechanical pinholes, iyo inki haibatanidzi zvachose pamusoro

Ramba wakatarira kuShunfeng Ink kuti uwane rumwe ruzivo nezve ingi-dzinobva mumvura, ingi dzeUV, uye mavarnish ane mvura.
