Bhodhoro regirazicoating chinhu chakakosha chepamusoro kurapwa chinongedzo mumunda wecosmetic packaging. Inowedzera jasi rakanaka kumudziyo wegirazi. Muchinyorwa chino, tinogovera chinyorwa nezve girazi bhodhoro pamusoro pekupfapfaidza kurapwa & hunyanzvi hwekufananidza ruvara.
Ⅰ、Girazi bhodhoro pendi yekupfapfaidza hunyanzvi hwekushanda kwekuvaka
1. Shandisa diluent yakachena kana mvura kugadzirisa pende kune viscosity yakakodzera yekupfapfaidza. Mushure mekuyera neTu-4 viscometer, iyo yakakodzera viscosity inowanzoita masekonzi gumi nemasere kusvika makumi matatu. Kana pasina viscometer panguva ino, unogona kushandisa nzira yekuona: fambisa pende netsvimbo (simbi kana danda rehuni) uye wozoisimudza kusvika pakakwirira 20 cm uye mira kuti uone. Kana iyo pende isingaputsi munguva pfupi (masekonzi mashoma), yakanyanya kukora; kana ikatsemuka ichingobva pamucheto wepamusoro webhakiti, yanyanya kuonda; painomira pahupamhi hwemasendimita makumi maviri, pende iri mumutsara wakarurama uye inomira kuyerera uye inodonha pasi pakarepo. Iyi viscosity inonyanya kukodzera.
2. Mhepo yemhepo inofanira kudzorwa pa 0.3-0.4 MPa (3-4 kgf / cm2). Kana kumanikidzwa kwakanyanyisa, mvura yependi haizove yakasvibiswa zvakanaka uye gomba richaumbwa pamusoro; kana kudzvinyirirwa kwakanyanyisa, kunopera nyore nyore uye mhute yepende ichave yakakura, iyo inoparadza zvinhu uye inokanganisa hutano hwemushandisi.
3. Chinhambwe chiri pakati pemhuno nechepamusoro chinowanzoita 200-300 mm. Kana iri padyo zvakanyanya, inodonha nyore; kana iri kure, mhute yepende ichave isina kuenzana uye gomba richaonekwa nyore, uye kana muromo uri kure nepamusoro, mhute yepende inobhururuka ichienda munzira, ichikonzera tsvina. Iyo chaiyo saizi yepakati inofanirwa kugadziridzwa zvinoenderana nerudzi, viscosity uye mhepo yekumanikidza yegirazi bhodhoro pendi. Nguva yekupfapfaidza pendi inononoka-inononoka inogona kuva kure, uye inogona kuva kure kana viscosity yakatetepa; kana mhepo yemhepo yakakwira, nguva yacho inogona kuva kure, uye inogona kuva pedyo kana kudzvinyirira kuri kuduku; iyo inonzi iri pedyo uye kure inoreva chiyero chekugadzirisa pakati pe10 mm ne50 mm. Kana ichipfuura chiyero ichi, zvakaoma kuwana firimu repende rakakodzera.
4. Pfuti yekupfapfaidza inogona kutamirwa kumusoro uye pasi, kuruboshwe uye kurudyi, zvichida pane imwe yunifomu ye 10-12 m / min. Iyo muromo inofanira kupfapfaidzwa yakatsetseka pamusoro pechinhu, uye oblique spraying inofanira kuderedzwa. Pakupfapfaidza kumativi ese epasi, ruoko rwakabata pfuti yekupuruzira runofanira kukurumidza kuburitswa kuderedza mhute yependi, nekuti migumo miviri yechiso chechinhu kazhinji inogashira maspray anopfuura maviri, uye ndidzo nzvimbo dzinodonha. zvingangoitika.
5. Paunenge uchipfapfaidza, iyo inotevera dhizaini inofanira kudzvanya 1/3 kana 1/4 yeiyo yapfuura layer, kuitira kuti pasave nekudonha. Paunenge uchipfapfaidza pendi inokurumidza kuomesa, zvinodikanwa kuipfapfaidza iyo yakarongeka panguva imwe chete. Mhedzisiro yekumwaya zvakare haina kunaka.
6. Paunenge uchipfapfaidza panzvimbo yakashama kunze, teerera kune kwainoenda mhepo (hazvina kufanira kushanda nemhepo ine simba), uye mushandisi anofanira kumira akananga kumhepo kudzivirira mhute yependi kuti isaputirwe pane yakapfapfaidzwa. pendi firimu uye kukonzera kunyadzisa granular pamusoro.
7. Kurongeka kwekupfapfaidza ndeku: kuoma kutanga, nyore gare gare, mukati mekutanga, kunze gare gare. High first, low later, small area first, big area gare gare. Nenzira iyi, mhute yependi yakapfapfaidzwa gare gare haizopfachukira pafirimu repende yakapfapfaidzwa uye kukuvadza firimu rependi rakapfapfaidzwa.
Ⅱ、Girazi bhodhoro pendi ruvara rwekufananidza hunyanzvi
1. Nheyo inokosha yevaravara
Tsvuku + yero = orenji
Tsvuku + yebhuruu = yepepuru
Yero + yepepuru = yegirini
2. Nheyo yekutanga yemavara anopindirana
Tsvuku uye girini zvinopindirana, ndiko kuti, tsvuku inogona kuderedza girini, uye girini inogona kuderedza mutsvuku;
Yero uye yepepuru inopindirana, ndiko kuti, yero inogona kuderedza yepepuru, uye yepepuru inogona kuderedza yero;
Bhuruu neorenji zvinopindirana, ndiko kuti, bhuruu inogona kuderedza orenji, uye orenji inogona kuderedza bhuruu;
3. Ruzivo rwekutanga rwemavara
Kazhinji, ruvara runotaurwa nevanhu rwakakamurwa kuita zvinhu zvitatu: hue, kureruka uye saturation. Hue inonziwo hue, kureva tsvuku, orenji, yero, girini, cyan, bhuruu, pepuru, nezvimwewo; kupenya kunonziwo kupenya, kunotsanangura kujeka uye rima reruvara; saturation inonziwo chroma, inotsanangura kudzika kweruvara.
4. Nheyo dzekutanga dzekuenzanisa kwemavara
Kazhinji, usashandise marudzi anopfuura matatu epende yekuenzanisa mavara. Kusanganisa dzvuku, yero uye yebhuruu mune imwe chikamu kunogona kuwana akasiyana epakati mavara (kureva mavara ane akasiyana hues). Pahwaro hwemavara ekutanga, kuwedzera chena kunogona kuwana mavara ane akasiyana saturations (kureva mavara ane akasiyana mimvuri). Pahwaro hwemavara ekutanga, kuwedzera dema kunogona kuwana mavara ane kureruka kwakasiyana (kureva mavara ane kupenya kwakasiyana).
5. Basic mavara anoenderana maitiro
Iko kusanganiswa uye kuenzanisa pendi kunotevera subtractive color musimboti. Iwo matatu ekutanga mavara akatsvuka, yero uye yebhuruu, uye iwo anowirirana mavara akasvibira, epepuru uye orenji. Iwo anonzi mavara anowirirana mavara maviri echiedza akasanganiswa mune imwe chikamu kuti awane chiedza chichena. Rudzi runopindirana rweruvara rutsvuku rwakasvibira, ruvara rweyero runopindirana rwepepuru, uye runopindirana ruvara rwebhuruu orenji. Ndiko kuti, kana ruvara rwakanyanya kutsvuka, unogona kuwedzera girini; kana yakanyanyisa yero, unogona kuwedzera yepepuru; kana yakanyanyisa bhuruu, unogona kuwedzera orenji. Iwo matatu mavara ekutanga dzvuku, yero, uye bhuruu, uye iwo anowirirana mavara akasvibira, epepuru, uye orenji. Iwo anonzi mavara anowirirana mavara maviri echiedza akasanganiswa mune imwe chikamu kuti awane chiedza chichena. Rudzi runopindirana rweruvara rutsvuku rwakasvibira, ruvara rweyero runopindirana rwepepuru, uye runopindirana ruvara rwebhuruu orenji. Ndiko kuti, kana ruvara rwakanyanya kutsvuka, unogona kuwedzera girini; kana yakanyanyisa yero, unogona kuwedzera yepepuru; kana yakanyanyisa bhuruu, unogona kuwedzera orenji.
Usati wafananidzwa neruvara, tanga waona nzvimbo yeruvara runofanira kuenderana nenhamba iri pazasi, wobva wasarudza maviri akafanana kuti aenderane mune imwe chikamu. Shandisa iyo yakafanana girazi bhodhoro bhodhi zvinhu kana workpiece kuti ipfapfairwe kuti ienderane neruvara (ukobvu hweiyo substrate, sodium yemunyu bhodhoro regirazi uye calcium munyu bhodhoro regirazi rinoratidza maitiro akasiyana). Kana uchifananidza ruvara, tanga wawedzera ruvara rukuru, uye wozoshandisa ruvara rune simba rakasimba rekupenda seyechipiri ruvara, zvishoma nezvishoma uye zvishoma nezvishoma wedzera uye simbisa nguva dzose, uye cherechedza kuchinja kwemavara chero nguva, tora sampuli uye pukuta, bhurashi, pfapfaidza. kana kunyura pamuenzaniso wakachena, uye enzanisa ruvara nemuenzaniso wekutanga mushure mekunge ruvara rwagadzikana. Nheyo ye "kubva kuchiedza kusvika kune rima" inofanirwa kubatwa mune yese ruvara rwekuenzanisa maitiro.
