Kudhinda pamafirimu-based self-adhesive materials kunogona kupa matambudziko, uye kubuda ropa kweinki idambudziko rinowanzosangana nevagadziri vanodhinda. Kudonha kweinki kunoreva kusasimba kwakashata kweakadhindwa inki layer pamusoro pechinhu nekuda kwezvinhu zvakaita sekuderera kwepasi tension., kusakwana UV kurapa, uye yakawandisa inki additives. Yakanyanya kudhinda ingi kurasikirwa hakungokanganisa chigadzirwa kunaka, asi zvinototungamira mukuraswa kwezvikwata zvezvigadzirwa. Muchinyorwa chino, tichaongorora zvikonzero zvitatu zvepamusoro zvekubuda ropa kweingi pane yakadhindwa firimu inonamira zvinhu uye nekupa mhinduro dzinoshanda dzekukunda dambudziko iri..
1. Kuderera kwepamusoro-soro kwezvinhu zvemufirimu
Chimwe chezvikonzero chikuru zvemadonhwe einki pane zvakadhindwa firimu-based self-adhesive zvinhu ndeye kuderera kwepasi tension yefirimu.. Kazhinji kutaura, iyo yakakwirira kushushikana kwepamusoro, zviri nani ingi fastness pashure kudhinda. Iko hakuna dambudziko nekukakavadzana kwepamusoro pezvizhinji zvemapepa-senge zvinhu, asi kudzvinyirirwa kwepamusoro kwezvinhu zvakaita semufirimu kazhinji hakuna kuenzana. Izvi zvakaderera pamusoro tension zvinogona kutungamirira kuurombo inki adhesion, izvo zvinogona kutungamira kudonhedza inki kudonhedza uye kudhinda mhando. Kana pane inki kurasikirwa panguva yokudhinda, iwe unogona kushandisa dyne peni kuti uedze kukosha kwekumanikidza kweiyo zvinhu. Kazhinji kutaura, zvinhu zvine tension yepasi yakaderera pane 38 datones anowanzoita kurasikirwa neingi. Kugadzirisa nyaya iyi, funga zvinotevera zvinogadzirisa:
A. Kurapa kwepamusoro: shandisa maitiro ekurapa kwepamusoro kuti uwedzere kushushikana kwepamusoro pezvinhu zvemufirimu. Izvi zvinogona kuwanikwa nekurapwa kwekorona, kurapwa kwemoto kana kurapwa kweplasma, iyo inogona kushandura maitiro epamusoro, kuwedzera kunyorova uye kukurudzira inki kunamatira.
B. Primer jasi: Isa rakakodzera primer jasi kune firimu zvinhu usati wadhinda. Primers anobatsira kugadzira chisungo pakati peinki uye pamusoro pezvinhu, kuvandudza inki adhesion uye kuderedza mukana inki kudonha. Bvunza mutengesi wako wekupotera kuti asarudze primer yakakodzera inoenderana nefirimu zvinhu uye inki kugadzirwa.. Mamwe makambani ekudhinda ehunyanzvi anodhinda anozoshandisawo zvakananga PET inozvinamira zvinhu zvekudhinda. Iyo yekupfekedza inoshandura iyo yekunyorova kwepamusoro maitiro ePET anozvinamira zvinhu, uye kuita kwakagadzikana, uye kusimba kweinki layer inogona kuvandudzwa zvinobudirira.
2. Kusakwana UV kurapa
Kusakwana UV kurapwa kunotungamira kune ingi madonhwe kana uchidhinda firimu-mhando yekuzvinamira zvinhu. Kusakwana kupora kunozokonzera inki layer isingawane kuoma kwakanyanya uye kunamatira, zvichiita kuti zvizora zvisina kunaka uye kukurumidza. Kuporeswa kusina kukwana kunoreva kuti mupendero wepamusoro weingi yekudhinda wakaomeswa uye waporeswa, asi mukati hamuna kupora zvachose. Iko kurasikirwa kwengi kunokonzerwa nemhando iyi yemamiriro ezvinhu kunowanzoitika mukudhindwa kwemaitiro makuru emunharaunda. Izvi zvinodaro nekuti mapatani enzvimbo hombe anoshandisa huwandu hwakawanda hweinki, uye mukati meiyo inki layer haisi nyore kurapa zvachose. Kugadzirisa nyaya iyi, unogona kutarisa kune zvinotevera mhinduro:
A. UV Kusimba uye Dose: Ita shuwa kuti UV yekurapa sisitimu yakarimwa zvakaringana uye inopa yakakwana UV kusimba uye dosage.. Tarisa uye gadzirisa UV kusimba mazinga kuti uwane yakakwana kurapwa kune chaiyo inki uye firimu zvinhu zviri kushandiswa.. Semuyenzaniso, mapatani akasviba anotora mwenje wakawanda weUV uye kazhinji anoda simba rakawanda kuti uome zvachose. Bvunza inki uye vagadziri vemidziyo inokurudzirwa UV yekurapa paramita.
B. Kurapa nguva uye tembiricha: gadzirisa nguva yekurapa uye tembiricha marongero kuti uve nechokwadi chekuratidzwa kwakakwana uye kuve nechokwadi chekuti inki layer yapora zvizere. Bvunza nhungamiro yemugadziri weinki yezvinokurudzirwa kurapa paramita uye gadzirisa zvinoenderana nemamiriro ekudhinda uye michina inoshandiswa..
C. Upenyu hwebasa remarambi eUV: Parizvino, hupenyu hwesevhisi hwemarambi eUV pane toppan kudhinda michina iri pakati 800 uye 1000 maawa. Kana marambi asina kuchinjwa kana hupenyu hwakatarwa hwapfuura, zviri nyore kuita kuti inki iome. Naizvozvo, pakutsiva UV rambi chubhu, zvakakosha kuita zvinyorwa zvakadzama, uye kana UV rambi chubhu yasvika kuhupenyu hwesevhisi, inofanira kutsiviwa nenguva.
3. Yakawandisa inki additives
Kuvepo kweakawandisa inki additives kunokonzeresa kudonha kweinki kana uchidhinda firimu-mhando yekuzvinamira zvinhu.. Mukudhinda, iyo inki yekudhinda inowanzosangana nematambudziko ekukora, high viscosity uye murombo inking. Naizvozvo, vazhinji vanoshanda vachasarudza kuwedzera varnish kuti vavandudze fluidity yekudhinda inki. Zvisinei, kana huwandu hwevarnish hunoshandiswa zvisina kunaka, zviri nyore kwazvo kukanganisa inki viscosity, pamusoro tension uye adhesion kuita, zvichiita kuti inki idonhe. Ndapota funga mazano anotevera kugadzirisa nyaya iyi:
A. Ink Formulations: Ongorora uye gadzirisa maumbirwo einki nechinangwa chekudzikisa kuwedzera kwekuwedzera. Sezvo zvisiri zvinhu zvese zvinogona kunyatsoenderana neingi, kuwana ingi chaiyo kunowanikwa zvakanyanya nekushanda pamwe chete nemutengesi weinki kugadzira tsika yeinki yekugadzira inoenzanisa zvimiro zveinki uye inoderedza njodzi yekudonha kweinki..
B. Kuenderana kuyedzwa: Tumira izvo kune mutengesi weinki kuti uedzwe kuti uone kuti iyo inki yekuwedzera inoshandiswa inoenderana neyakagadzirwa firimu uye kudhinda maitiro.. Kuenderana kuyedzwa kunoitwa pakati peinki uye firimu zvinhu kuona chero kudyidzana kana kusapindirana kunogona kukonzera kudonha kweinki.. Edza maumbirwo einki akasiyana uye gadzirisa mazinga ekuwedzera kuti uwane iyo yakanakisa musanganiswa inopa yakanaka kunamatira uku uchideredza kudonha kweinki..
Mhedziso
Kukunda matambudziko ekudhinda inki droplet mune firimu-based self-adhesive zvinhu zvinoda maitiro akawanda.. Nekugadzirisa zvikonzero zvekuderera kwepasi tension, kusakwana UV kurapa uye yakawandisa inki additives, maprinta anogona kuvandudza zvakanyanya inki adhesion uye kuwana zvirinani kudhinda mhando. Gadzirisa kurapwa kwepamusoro kana majasi ekutanga kuti uwedzere kushushikana kwepamusoro, shongedza UV kurapa paramita kuti uwane yakazara inki kurapwa, uye kunyatso-tune inki magadzirirwo kuderedza kushandiswa kwekuwedzera kwekuwedzera. Nekutora mhinduro idzi, vagadziri vanogona kukunda matambudziko ekudonhedza inki uye kugadzira maprinta emhando yepamusoro pafirimu-based self-adhesive materials.
