Het beste product is doorgaans het product dat dit defect verhelpt binnen het veiligste compatibiliteitsbereik.<\/p>\n<p><!-- lc-qa-end --><\/p>\n<p>1. Overzicht van nivellering<\/p>\n<p>After the construction of paint, there is a flow and drying film-forming process, and then gradually form a flat, smooth, uniform coating film. Whether the coating film can achieve the characteristics of flat and smooth is called leveling. In the actual construction process of the coating, the film defects that often appear are orange peel, fish-eye, shrinkage, pinhole, shrinkage, Benedict swirl, air sensitivity and due to poor leveling, brush marks when brushing, roller coating roller marks are known as poor leveling, the generation of these phenomena reduces the decorative and protective function of the coating. There are many factors affecting the leveling of coatings, such as solvent volatility gradient and solubility properties, surface tension of coatings, wet film thickness and surface tension gradient, rheology of coatings, construction process and environment, etc., of which the most important factors are the surface tension of coatings, surface tension gradient generated by the wet film in the film-forming process and the surface tension homogenization of the surface layer of the wet film. To improve the leveling of coatings, it is necessary to consider adjusting the formulation and adding suitable additives. In practice, <a href=\"https:\/\/longchangchemical.com\/nl\/product\/chlumile3345-silicone-leveling-agents-wetting-leveling-agents\/\">CHLUMILE 3345 Leveling Agent<\/a> en <a href=\"https:\/\/longchangchemical.com\/nl\/product\/chlumile3033-organic-silicone-leveling-agent-automotive-paint-leveling-agent\/\">CHLUMILE 3033 Leveling Agent<\/a> are often compared so that the coatings have suitable surface tension and the ability to reduce the surface tension gradient.<br \/>\n2. Rol van nivelleringsmiddel<br \/>\nNa het bevochtigen van het substraat worden de additieven die het vloeien van de coating tot de uiteindelijke nivellering regelen nivelleermiddelen genoemd, die de volgende problemen kunnen oplossen<br \/>\n3. De belangrijkste be\u00efnvloedende factoren van nivellering<br \/>\n3.1. Oppervlaktespanningsgradi\u00ebnt - grensvlak vloeistof-lucht<br \/>\nOppervlaktespanningsgradi\u00ebnten in de binnenste en buitenste lagen leiden tot Benadryl-wervelingen<br \/>\nEliminatie van de oppervlaktespanningsgradi\u00ebnt is een essentieel element in het verkrijgen van een vlak oppervlak.<br \/>\n3.2. Oppervlaktespanning -- grensvlak vloeistof\/vaste stof<br \/>\nLagere oppervlaktespanning dan het substraat, zodat de coating het substraat beter bevochtigt<br \/>\nLagere oppervlaktespanning van de coating, wat leidt tot een betere nivellering van de vloeistof over lange golven.<br \/>\n4. Be\u00efnvloedende factoren van nivelleersnelheid<br \/>\nHoe hoger de viscositeit, hoe langzamer de nivellering.<br \/>\nHoe dikker de folie, hoe sneller je egaliseert.<br \/>\nHoe hoger de oppervlaktespanning, hoe sneller de nivellering.<br \/>\n5.
