Amathiphu ngaphambi kokwakhiwa kwe-pearlescent i-powder coating

I-pigment ye-pearlescent ene-transparent engenambala, inkomba ye-refractive ephezulu, isakhiwo sesendlalelo se-foil eqondisayo, emisebe yokukhanya, ngemva kokuphindaphinda okuphindaphindiwe, ukuboniswa kanye nokubonisa ukucwazimula. iparele umbala okhanyayo. Akukhona noma yikuphi ukuvunyelwa kwe-pigment platelet okungaveza umphumela we-crystal sparkle, ukuze kwakhe iparele futhi umbala, imfuneko yisimo se-lamellae pearlescent pigments are parali-lel komunye nomunye futhi ihlelwe ngemigqa eduze kwendawo yokumboza.
Ukwakhiwa kwama-varnishes namapende, ama-pigment e-pearlescent alandela imithetho ye-physics, okungukuthi i-platelet pigment ekugelezeni kwe-liquid izoba ngokuhambisana nesiqondiso sokugeleza kwemigqa yabo.
Ukufafaza upende lapho amaconsi kapende engqubuzana nesenzo sokugeleza kwendawo ezogqitshwa futhi inwetshwe phakathi nesikhathi esilinganiselwe, ngokuvamile akwazi ukuhlangabezana nezidingo zokugeleza ezi-odwe nge-lamellar pigment. Ezinye izindlela zokwakha zokuxubha, ukugqoka okugeleza noma ukucwiliswa kwe-dip, kungase futhi kube nengxenye yokugeleza kunganelisa indima yokuqondanisa yamaplatelet.
Ngemuva kokunyuka kwe-viscosity ngenxa yokomisa, ukusabela kwe-thixotropic noma kwamakhemikhali kanye nokwakheka kwesimo sezingulube kuhlelwe emigqeni kuhleliwe. Isendlalelo sikapende wombala simanzi, izinga lokuhwamuka eliphansi le-solvent, okungafanele izinga lokushisa le-thixotropic noma isisekelo sokwakhiwa kwe-viscosity lihamba kancane kakhulu noma sekwephuze kakhulu, i-pigment lamellae iyakwazi ukubuyela kunoma iyiphi i-oda. Lokhu kubangele ukulahlekelwa okucwebezelayo. Ngokuphambene nalokho, i-volatilization ye-solvent ukuze unciphise isikhathi sokumisa se-coating ukuze kube nenzuzo. Uma enamathela ezimanzi ifinyelela ukushuba ethile, futhi wahlela emigqeni ye-pigment platelets nzima.
Ukucwebezela kwe-pigment ye-pearlescent ekuncikeni kwesiqondiso komunye umbono, kungasetshenziswa ukudala umphumela wokuhlobisa omningi ongajwayelekile, isb umphumela ofayo noma ukhuni lokuhlobisa olunomumo ongaphezulu wemibala ekhanyayo. I-Pearlescent automotive coatings indlela engcono kakhulu yokwakha iyindlela yokufafaza yakudala, umphumela omuhle weparele ngemuva kokwakhiwa kwayo.

Ukwakhiwa kufanele kunake inkinga:

1. Pre-ukwakhiwa, upende kufanele Govuze;
2. Ukusebenza okukhulu okuqhubekayo kokuma-enamathela isidingo sezinyathelo zokulwa nokuhlaliswa;
3. Ukufafaza kufanele kunake ibanga lesibhamu, isibhamu sesivinini sokuhamba okufanayo, kanye nokwakhiwa akufanele kube okukhulu kakhulu
