Girazi bhodhoro rekuputira, mumunda wezvizoro zvekurongedza zvinhu, ichi chakakosha chepamusoro chekurapa chinongedzo, anowedzera runako kune girazi mudziyo, mune ino chinyorwa, tinogovera chinyorwa chegirazi bhodhoro pamusoro pekupfapfaidza kurapwa & hunyanzvi hwekufananidza ruvara muShanghai rainbow package.
一,
Girazi bhodhoro pendi yekupfapfaidza unyanzvi hwekushanda kwekuvaka
1. Shandisa diluent yakachena kana mvura kugadzirisa pende kune viscosity yakakodzera yekupfapfaidza. Iyo viscosity yakakodzera inowanzo 18 kusvika 30 masekonzi sekuyerwa neTu-4 viscometer. Kana pasina viscometer kwechinguva, nzira yekuona inogona kushandiswa: fambisa pende netsvimbo (simbi kana danda rehuni) uye uisimudze kusvika pakakwirira 20 cm kuti urege kutarisa. Yakanyanya kukora; kana mutsara wakaputsika pakarepo uchibva kumucheto wepamusoro webhodhoro, yakanyanya kuonda; painomira pahupamhi hwemasendimita makumi maviri, mvura yepende ichaita mutsara wakarurama, uye kuyerera kunomira pakarepo uye kudonha. Iyi viscosity inonyanya kukodzera.
2. Mhepo yemhepo inonyanya kudzorwa pa 0.3-0.4 MPa (3-4 kgf / cm2). Kana kudzvinyirirwa kwakanyanya kuderera, mvura yependi ichave isina kusimba atomized, uye gomba richaumbwa pamusoro; kana kudzvinyirirwa kwakanyanyisa, kuchanyura nyore nyore, uye mhute yepende ichave yakakura, iyo isingazorashi zvinhu chete, asiwo inokanganisa hutano hwemuiti.
3. Nguva yepakati pakati pemuromo nechinhu chiri pamusoro pe200-300 mm. Kunyanya pedyo, zviri nyore kusagi; kure kwazvo, mhute yependi haina kuenzana uye inowanzoita gomba, uye mhute yepende inopararira munzira kubva pamuromo kure nechinhu chiri pamusoro, ichikonzera tsvina. Hukuru chaihwo hwepakati hunofanirwa kugadziridzwa zvakakodzera azvinoenderana nerudzi rwegirazi bhodhoro pendi, viscosity uye mhepo yekumanikidza. Nguva yekupfapfaidza yepende inononoka-inoomesa inogona kuva kure, kana viscosity yakaonda, inogona kuva kure; kana mhepo yemhepo yakakwira, nguva yacho inogona kuva kure, uye kudzvinyirira kunogona kuva kuduku kana kudzvinyirira kuri kuduku; Kana ikadarika chiyero ichi, zvinova zvakaoma kuwana firimu repende rakakodzera.
4. Pfuti yekupfapfaidza inogona kutamirwa kumusoro uye pasi, kuruboshwe uye kurudyi, zvichinyanya kumhanya 10-12 m / min, uye muromo unofanirwa kupfapfaidzwa pamusoro pechinhu kuti kuderedze oblique spraying. Pakupfapfaidza kumativi ose echinhu pamusoro pechinhu, ruoko runodhonza pfuti yespray inofanira kusunungurwa nokukurumidza kuderedza mhute yepende. Nekuti migumo miviri yechinhu chacho kazhinji inoda kumwaya kanopfuura kaviri, ndiyo inonyanyo konzeresa kudonha.
5. Paunenge uchipfapfaidza, chinopfuura chinotevera chinofanira kudzvanywa chinopesana ne 1/3 kana 1/4 yepasi yapfuura, kuitira kuti pasave nekudonha kwepfapfaidzo. Paunenge uchimwaya pendi inokurumidza kuomesa, pfapfaidza ichitevedzana panguva. The spray effect haina kunaka.
6. Paunenge uchipfapfaidza munzvimbo yakavhurika yekunze, teerera kune kwakanangana nemhepo (usashande kana mhepo ine simba), uye mushandisi anofanira kumira kudivi remhepo kudzivirira mhute yepende kuti isapeperedzwe nemhepo kuenda kune yakapfapfaidzwa. pendi firimu uye kukonzera inonyadzisa granular pamusoro.
7. Kurongeka kwekupfapfaidza: kutanga kwakaoma uye zvakare nyore, kutanga mukati uye kunze. Kutanga kumusoro, kozoti kwakaderera, kwekutanga nzvimbo diki uyezve nzvimbo hombe. Nenzira iyi, mhute yependi yakapfapfaidzwa haizopfachukira pafirimu repende yakapfapfaidzwa uye kukuvadza firimu rependi rakapfapfaidzwa.

Girazi bhodhoro pendi ruvara rwekufananidza hunyanzvi
1. Nheyo yekutanga yekunaka
tsvuku + yero = orenji
tsvuku + bhuruu = pepuru
yero + yepepuru = girini
2. Nheyo inokosha yemavara anowirirana
Tsvuku uye girini zvinopindirana, ndiko kuti, tsvuku inogona kuderedza girini, uye girini inogona kuderedza mutsvuku;
Yero uye yepepuru zvinopindirana, ndiko kuti, yero inogona kuderedza yepepuru, uye yepepuru inogona kuderedza yero;
Bhuruu inopindirana neorenji, ndiko kuti, bhuruu inogona kuderedza orenji, uye orenji inogona kuderedza bhuruu;
3. Mavara ekutanga
Vanhuwo zvavo vanoti ruvara 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,iyo inotsanangura kudzika kweruvara.
4. Nheyo dzekutanga dzekufananidza mavara
Kazhinji usashandise anopfuura matatu marudzi epende yemavara. Akasiyana epakati mavara (kureva, mavara ane toni dzakasiyana) anogona kuwanikwa nekusanganisa tsvuku, yero, uye yebhuruu mavara mune imwe chikamu. Pahwaro hwemuvara wekutanga, uchiwedzera chena, unogona kuwana mavara ane akasiyana saturation (kureva, mavara ane akasiyana shades). Pahwaro hwemuvara wekutanga, uchiwedzera dema, unogona kuwana mavara nekureruka kwakasiyana (kureva, mavara ane kupenya kwakasiyana).
5. Hunyanzvi hwekubatanidza mavara
Kusanganiswa uye kuenderana kwemavara ependi kunotevera musimboti wekubvisa ruvara, iwo matatu ekutanga mavara akatsvuka, yero, uye bhuruu, uye iwo anopindirana mavara akasvibira, epepuru, uye orenji. Anonzi mavara anopindirana mavara maviri akasanganiswa mune imwe chikamu kuti awane chiedza cheruvara ruchena, ruvara runoenderana nerutsvuku rwakasvibira, runopindirana rweyero rwepepuru, uye runopindirana rweruvara rweblue 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. Aya anonzi mavara anowirirana mavara maviri akasanganiswa mune imwe chikamu kuti awane chiedza cheruvara ruchena, ruvara runoenderana nerutsvuku rwakasvibira, runopindirana rweyero rwepepuru, uye runopindirana rweruvara rweblue 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 kuti ruvara runofanira kusanganiswa rwuri papi pamufananidzo zvichienderana nenhamba inotevera, wobva wasarudza mavara maviri akafanana ekubatanidza mune imwe chikamu. Shandisa iyo imwechete girazi bhodhoro bhodhoro zvinhu kana workpiece kuti ipfapfairwe kuti ienderane neruvara (ukobvu hwe substrate, bhodhoro regirazi remunyu re sodium uye bhodhoro regirazi remunyu recalcium rinoratidza maitiro akasiyana). Paunenge uchisanganisa ruvara, tanga wawedzera iyo huru ruvara, wobva washandisa iyo ruvara ine yakasimba tinting simba seyebetsero, zvishoma nezvishoma uye nepakati wedzera uye ramba uchikurudzira, kuona shanduko yeruvara chero nguva, uye tora sampuli nekupukuta, kukwesha, kupfapfaidza kana kunamira pamuenzaniso wakachena. Mushure mokunge ruvara rwagadzikana, enzanisa ruvara nemuenzaniso wekutanga. Muchiitiko chese chekuenzanisa kwemavara, chirevo che "kubva pakadzika kusvika kune rima" chinofanira kubatwa.
