Pearlescent poda coating, Mazano asati avakwa

Mazano asati avakwa pearlescent powder coating

Iyo pearlescent pigment ine isina ruvara yakajeka, yakakwirira refractive index, yakananga foil layer chimiro, muchiedza chemwenje, mushure mekudzokororwa kudzokororwa, kuratidza uye kuratidza kupenya. pera luster pigment. Kwete chero mvumo yepigment maplatelet inogona kuburitsa kristaro inopenya mhedzisiro, kuitira kuti igadzire parera uye. ruvara, chinodiwa ndiyo mamiriro e lamellae pearlescent pigments ari parallel kune mumwe nemumwe uye yakarongedzwa mumitsara pamwe nepamusoro peiyo jasi.
Kuvakwa kwevarnish uye pendi, pearlescent pigments inoteedzera mitemo yefizikisi, iyo platelet pigment mukuyerera kwemvura ichaenderana negwara rekuyerera kwemitsara yavo.
Kupfapfaidza pendi kana madonhwe ependi achidhumhana nekuyerera kwechiito chepamusoro kuti avharwe uye awedzererwe mukati menguva shoma, kazhinji akakwanisa kusangana nelamellar pigment-akaraira kuyerera zvinodiwa. Dzimwe nzira dzekuvaka dzekubhurasha, kuyerera kwekuvhara kana dip coating, inogona zvakare kuve nechikamu chekuyerera inogona kugutsa basa rekurongeka remaplatelet.
Mushure mokunge viscosity inowedzera nekuda kwekuoma, thixotropic kana makemikari maitiro uye kuumbwa kwehurumende yepigments inorongwa mumitsara inogadziriswa. Iyo pendi pendi yakakora yakanyorova, yakaderera evaporation mwero weiyo solvent, isina kufanira iyo thixotropic kana base yekuvaka tembiricha viscosity kuwedzera inononoka kana kunonoka, iyo pigment lamellae inokwanisa kudzoka kune chero yakarongeka. Izvi zvakonzera kurasikirwa kwekupenya. Kusiyana neizvi, kuvhuvhuta kweiyo solvent kuitira kupfupisa nguva yekuomeswa kwejasi kuti ibatsire. Kana kunyorova coating inosvika imwe ukobvu, uye akaronga mumitsara pigment maplatelet zvakaoma.
Kubwinya kwepearlescent pigment padanho rekutsamira kweimwe maonero, inogona kushandiswa kugadzira akawanda easina kujairika chimiro chekushongedza maitiro, eg iyo inofa mhedzisiro kana yekushongedza huni ine chimiro chepamusoro chemavara ane shading. Pearlescent mota machira akanakisa ekuvaka nzira imhando yekupfapfaidza nzira, yakanakisa pearl mhedzisiro mushure mekuvakwa kwayo.

Kuvaka kunofanirwa kutarisa kune dambudziko:

1. Pre-kuvaka, iyo pendi inofanira Kukurudzira;
2. Yakakura-yakakura inoenderera mberi kushanda kwekumira-kupfekedza kudiwa kweanopesana nekugadzirisa matanho;
3. Kupfapfaidza kunofanirwa kutarisisa kureba kwepfuti, yunifomu yekufamba kumhanya pfuti, kamwe kuvaka hakufanirwe kunge kwakakora
