Gwaro: Kudhinda sirika inzira yakajairika yekudhinda mifananidzo mukugadzira zvinhu zvekushongedza. Kuburikidza nekubatanidza inki, skrini yekudhinda skrini, uye michina yekudhinda skrini, inki inotamisirwa ku substrate kuburikidza ne mesh yechikamu chemifananidzo. Munguva yekuita, kudhinda skrini Ruvara ruchakanganiswa nezvimwe zvinhu uye shanduko. Nyaya ino yakarongwa napasuru yemuraraungu yeShanghai, uye ndichakuudzai zvinhu zvakati wandei zvinokanganisa kuchinja kweruvara rwechidzitiro chesiriki.
kudhinda sikirini
Maitiro ekudhinda skrini ndeekuti inki inopfuura nepakati pemesh yechidzitiro yobva yadonhera pasi pevhu. Chikamu chasara chechidzitiro chinovharika uye inki haigone kupinda. Pakudhinda, inki inodururwa pasi pechidzitiro. Pasina simba rekunze, inki haizodonhedzi nepamesh ichienda pasi pevhu. Kana squeegee ikakwenya inki ne pressure yakati uye tilt angle, inozopfuudzwa nepachidzitiro. Ku substrate inotevera kuti ione kopi yemufananidzo.
01 Kusanganisa ingi
Kana tichifunga kuti mavara ari muinki akagadzirwa zvakanaka, chikonzero chinowanzoita kuti ruvara ruchinje ndiyo solvent yakawedzerwa. Muworkshop inodzorwa zvakanaka, inki inofanira kupihwa kumuchina wekudhinda chero nguva mushure mekunge yagadzirwa, kureva kuti, muchina wekudhinda haufanirwe kusanganisa inki. Mumakambani mazhinji, inki haigadziriswe uye haipihwe kumuchina wekudhinda, asi inosiyirwa kumaprinta kuti agadzirise, uye vanowedzera nekusanganisa inki zvichienderana nemanzwiro avo. Nekuda kweizvozvo, chiyero chepigment muinki chinotyoka. Kune inki yakajairika inobva mumvura kana UV, mvura iri muinki inoshanda zvakafanana ne solvent iri muinki yesolvent. Kuwedzera mvura kuchatetepa firimu reinki yakaomeswa uye kukanganisa ruvara rweinki, nokudaro zvichideredza density yeruvara. . Zvikonzero zvematambudziko akadaro zvinogona kuteverwa mberi.
Mudura reinki, vashandi vanosanganisa inki havashandisi mudziyo wekuyera, uye vanongovimba nepfungwa dzavo kuti vawedzere huwandu hwakakodzera hwechinhu chinonyungudutsa, kana kusanganisa kwekutanga kusina kukodzera, kana huwandu hwekusanganisa inki hwakachinja panguva yekudhinda, kuitira kuti inki yakasanganiswa ibudiswe. Kana basa iri rikadhindwa zvakare mune ramangwana, mamiriro ezvinhu aya achatowedzera kuipa. Kunze kwekunge paine inki yakakwana yekurekodha, hazvigoneke kuburitsa ruvara zvakare.
02 Sarudzo yechidzitiro
Dhayamita yewaya yechidzitiro uye nzira yekuruka, kureva kuti, plain kana twill, zvine simba guru pakukora kwefirimu yeinki yakadhindwa. Mupi wechidzitiro achapa ruzivo rwakadzama rwehunyanzvi rwechidzitiro, huwandu hweinki yedzidziso inonyanya kukosha, iyo inomiririra huwandu hweinki inopfuura nepamachira echidzitiro pasi pemamwe mamiriro ekudhindisa, anowanzo ratidzwa mu cm3/m2. Semuenzaniso, skrini ye 150 mesh/cm ine dhayamita ye 31μm ichakwanisa kupfuura 11cm3/m2 yeinki. Mesh ine dhayamita ye 34μm uye skrini ye 150-mesh ichapfuura 6cm3 yeinki pa square meter, iyo yakaenzana ne 11 ne 6μm ukobvu yeinki yakanyorova. Zvinogona kuonekwa kubva pane izvi kuti kuratidzwa kuri nyore kwe 150 mesh kuchaita kuti uwane ukobvu hwakasiyana zvikuru hwemachira einki, uye mhedzisiro yacho ichakonzera mutsauko mukuru muruvara.
Nekuvandudzwa kwetekinoroji yekuruka waya, zvakakosha kuwana huwandu hwakati hwe twill wire mesh panzvimbo pe plain wire mesh. Kunyangwe izvi dzimwe nguva zvichikwanisika, mukana wacho mudiki kwazvo. Dzimwe nguva vatengesi vema screen vanochengeta mamwe ma twill screen ekare. Kazhinji, huwandu hwe inki yedzidziso yema screen aya hunosiyana ne10%. Kana ukashandisa twill weave screen kudhinda mifananidzo yakacheneruka, chiitiko chekutyoka kwemutsara mudiki chinopfuura che plain weave screen.
03Kushushikana kwechidzitiro
Kudzika kwesimba rechidzitiro kuchaita kuti chidzitiro chiparadzane zvishoma nezvishoma nepamusoro pechinyorwa, izvo zvinokanganisa inki inogara pachidzitiro uye zvinokonzera migumisiro yakadai sekusiyana kwemavara. Nenzira iyi, ruvara runoita serwakachinja. Kuti dambudziko iri rigadziriswe, kureba kwechidzitiro kunofanirwa kuwedzerwa, kureva kuti, kureba kuri pakati peplate yechidzitiro yakaiswa yakatwasuka nezvinhu zvekudhinda kunofanirwa kuwedzerwa. Kuwedzera kureba kwechidzitiro zvinoreva kuwedzera kumanikidzwa kwechinhu chinotsvedza, izvo zvinokanganisa huwandu hweinki inopfuura nepachidzitiro uye zvichikonzera shanduko huru muruvara.
04Kugadzika kwe squeegee
Kana squeegee yashandiswa yakapfava, inki yakawanda ichapfuura nepachidzitiro. Kana kumanikidzwa kwacho kuchinyanya kushanda pasqueegee, mupendero weblade wesqueegee unokurumidza kupera panguva yekudhinda. Izvi zvinochinja nzvimbo yekubatana pakati pesqueegee nechinhu chakadhindwa, izvo zvinochinjawo huwandu hweinki inopfuura nepachidzitiro, uye nokudaro Zvinokonzera shanduko dzeruvara. Kuchinja kona yesqueegee kuchakanganisawo huwandu hweinki inonamira. Kana squeegee ikamhanya zvakanyanya, izvi zvinoderedza ukobvu hweinki yakabatana.
05Kugadzika banga rekudzorera inki
Basa rebanga rinodzosa inki nderekuzadza maburi echidzitiro neinki yakagadzikana. Kugadzirisa kumanikidzwa, kona uye kupinza kwebanga rinodzosa inki kuchaita kuti mesh izadzwe zvakanyanya kana kuti isazadzwe zvakakwana. Kumanikidzwa kwakanyanya kwebanga rinodzosa inki kuchaita kuti inki ipfuure nepamesh, zvichikonzera kunamira kwakanyanya kweinki. Kusamanikidzwa kwakakwana kwebanga rinodzosa inki kuchaita kuti chikamu chemesh chizadzwe neinki, zvichikonzera kunamira kwakakwana kweinki. Kumhanya kwebanga rinodzosa inki kwakakoshawo zvikuru. Kana ikamhanya zvishoma nezvishoma, inki inozadza; kana ikamhanya nekukurumidza, inokonzera kushomeka kukuru kweinki, izvo zvakafanana nekuchinja kumhanya kwemuchina unosvetukira.
06Kugadzika kwemuchina
Kudzora maitiro nekungwarira ndicho chinhu chikuru chakakosha. Kugadziriswa kwakasimba uye kwakasimba kwemuchina kunoreva kuti ruvara rwacho rwakasimba uye rwakafanana. Kana kugadziriswa kwemuchina kuchichinja, ipapo ruvara rucharasikirwa nekudzora. Dambudziko iri rinowanzoitika kana vashandi vekudhinda vachichinja mashift, kana vashandi vekudhinda gare gare vachichinja marongero emuchina wekudhinda pavanoda kuitira kuti vagadzirire maitiro avo, izvo zvinozokonzera shanduko dzemavara. Muchina wekudhinda wemazuva ano une mavara akawanda unoshandisa computer automatic control kubvisa mukana uyu. Ita kuti marongero aya akasimba uye anowirirana emuchina wekudhinda uye chengetedza marongero aya asina kuchinja panguva yese yekudhinda.
07Zvinhu zvekudhinda
Muindasitiri yekudhinda masikirini, chinhu chinowanzo furatirwa kuenderana kwe substrate inofanira kudhindwa. Mapepa, kadhibhodhi nepurasitiki zvinoshandiswa pakudhinda zvinowanzogadzirwa muzvikamu. Mutengesi wemhando yepamusoro anogona kuvimbisa kuti zvinhu zvose zvaanopa zvine kutsetseka kwakanaka pamusoro, asi zvinhu hazvisi nguva dzose. Munguva yekugadzirisa zvinhu izvi, chero shanduko diki mukuita kwayo ichachinja ruvara neruvara rwezvinhu. Kupera kwepamusoro. Kana izvi zvaitika, ruvara rwakadhindwa runoita seruchichinja, kunyangwe pasina chakachinja panguva yekudhinda chaiko.
Patinoda kudhinda patani imwechete pazvinhu zvakasiyana-siyana, kubva pabhodhi repurasitiki rakarukwa kusvika pakadhibhodhi remifananidzo yakanaka, sekushambadzira kwekushambadzira, vadhindi vachasangana nematambudziko aya anoshanda. Rimwe dambudziko ratinowanzo sangana naro nderekuti kudhinda kwedu pachidzitiro kunofanira kusvika pamufananidzo we offset. Kana tikasateerera kudzora maitiro, hatina mukana. Kudzora maitiro nekungwarira kunosanganisira kuyera mavara nemazvo, kushandisa spectrophotometer kuona ruvara rwemutsetse, uye densitometer kuona mavara matatu makuru, kuitira kuti tigone kudhinda mifananidzo yakagadzikana uye yakafanana pazvinhu zvakasiyana-siyana.
08chiedza chinobva
Pasi pechiedza chakasiyana, mavara anotaridzika zvakasiyana, uye maziso evanhu anonyatsonzwa shanduko idzi. Izvi zvinogona kuderedzwa nekuona kuti mavara epigments anoshandiswa mukudhinda kwese akarurama uye akafanana. Kana ukachinja vatengesi, izvi zvinogona kuva njodzi. Kuyerwa kwemavara uye kuona zvinhu kwakaoma zvikuru. Kuti uwane kutonga kwakanakisa, panofanira kuva nedenderedzwa rakavharwa rinoumbwa nevagadziri veinki, kusanganisa inki, kuongorora uye kuyera kwakarurama mukudhinda.
09 yakaoma
Dzimwe nguva ruvara runochinja nekuda kwekusagadziriswa zvakanaka kwemuchina wekuomesa. Pakudhinda bepa kana kadhibhodhi, kana tembiricha yekuomesa ikagadziriswa zvakanyanya, mamiriro ezvinhu akajairika ndeekuti ruvara ruchena runoshanduka kuita yero. Maindasitiri egirazi neceramic anonyanya kunetseka nekuchinja kwemavara panguva yekuomesa kana kubheka. Pigment inoshandiswa pano inofanira kuchinjwa zvachose kubva paruvara rwakadhindwa kuenda kune ruvara rwakatsveyamiswa. Aya mavara akatsveyamiswa haangokanganisi chete netembiricha yekubikira, asiwo neoxidation kana kudzikira kwehunhu hwemhepo munzvimbo yekubikira.
