IPearlescent powder yokwambathisa, Iingcebiso ngaphambi kokwakhiwa

Iingcebiso ngaphambi kokwakhiwa kwepearlescent yengubo

Ipearlescent pigment enesalathiso esingenambala esingacacanga, esinereferensi ephezulu, isakhelo sefoyile eyalathisekileyo, kwimitha yokukhanya, emva kokuphinda-phinda ukuphinda-phinda, ukubonakalisa kunye nokubonisa ukukhazimla. iparele umbala oqaqambileyo. Akukho nakuphi na ukuvunyelwa kweeplatelet ze-pigment kunokuvelisa i-crystal sparkle effect, ukuze yenze iperile kwaye umbala, imfuneko yimeko ye-lamellae pearlescent pigments are parallel omnye komnye kwaye icwangciswe ngokwemiqolo ecaleni komphezulu wengubo.
Ukwakhiwa kweevanishi kunye neepeyinti, iipearlescent pigments zilandela imithetho yefiziksi, oko kukuthi iplatelet pigment ekuhambeni kolwelo luya kuhambelana nolwalathiso lokuhamba kwemiqolo yabo.
Ukutshiza iipeyinti xa amathontsi epeyinti engqubuzana nentshukumo yokuhamba komphezulu ukuba igqunywe kwaye yandiswe ngaphakathi kwexesha eliqingqiweyo, ngokuqhelekileyo ikwazi ukuhlangabezana neemfuno zokuqukuqela kwe-lamellar pigment. Ezinye iindlela zokwakha zokuxubha, ukugubungela ukuhamba okanye ukudibanisa idiphu, nayo ingaba necandelo lokuhamba linokwanelisa indima yokulungelelanisa iiplatelet.
Emva kokunyuka kwe-viscosity ngenxa yokomisa, i-thixotropic okanye i-chemical reactions kunye nokubunjwa kobume be-pigments ihlelwe kwimiqolo ehleliweyo. Umaleko wepeyinti yombala oshinyeneyo umanzi, izinga lokunyuka komphunga eliphantsi le-solvent, engafanelekanga i-thixotropic okanye isiseko sokwakhiwa kweqondo lobushushu bokwanda kwe-viscosity iyacotha okanye kade kakhulu, i-pigment lamellae iyakwazi ukubuyela kuyo nayiphi na indlela. Oku kubangele ilahleko yeglosi. Ngokuchasene noko, ukuguquguquka kwe-solvent ukwenzela ukunciphisa ixesha lokumisa i-coating ibe luncedo. Ukuba i-coating emanzi ifikelela kubukhulu obuthile, kwaye ihlelwe kwimiqolo ye-pigment platelets nzima ngakumbi.
Iglosi yepearlescent pigment ekuxhomekeke kwicala lomnye umbono, ingasetyenziselwa ukwenza uninzi lwemilo engaqhelekanga isiphumo sokuhombisa, umz. isiphumo sokufa okanye umthi wokuhombisa onemilo engaphezulu yemibala enemibala. I-Pearlescent i-automotive coatings eyona ndlela yokwakhiwa kweyona ndlela yindlela yokutshiza, eyona mpembelelo intle yeperile emva kokwakhiwa kwayo.

Ulwakhiwo kufuneka luthathele ingqalelo ingxaki:

1. Ngaphambi kokwakhiwa, ipeyinti kufuneka iGxume;
2. Umsebenzi omkhulu oqhubekayo wokumisa i-stand-coating imfuneko yamanyathelo okulwa nokuhlaliswa;
3. Ukutshiza kufuneka kuthathelwe ingqalelo umgama wompu, umpu wesantya sokuhamba okufanayo, kanye ukwakhiwa akufuneki kutyebe kakhulu
