Summary of English vocabulary and notes for common problems in coating production

1 The hair mixing clouding varnish or diluent presents cloud like opacity due to the precipitation of insoluble matter 2 The thickening phenomenon of thickening coating caused by the loss of diluent during storage 3 The phenomenon that flocculation forms agglomerates in paint or dispersion 4 The phenomenon that gelling coating changes from liquid state to unusable solid or semi-solid state 5 Skinning coating in the container, due to the oxidation polymerization, the phenomenon of forming a skin film on the liquid surface 6 The phenomenon that the solid component of settling coating sinks to the bottom of the container when it is in the container 7 Caking: the particles such as pigments and physical pigments in the paint are precipitated into dense lumps which are not easy to be redistributed by stirring 8 there are coarse particles (i.e., crusts, gelatin, agglomerates or foreign coarse grains) in coarse seedy coating during storage 9 The phenomenon that the fineness of the back to rough pig Shin color paint is poor due to the flocculation of the pigment during storage 10 Blooming: in the process of storage or drying, one or more paints with different pigment mixtures are separated or floated out, and on the surface of the paint or film, there are stripes and spots with uneven colors 11 Extreme condition of floating flowers 12 Bubbling bubbles are bubbles of air or solvent vapor or both formed in the coating process, which can disappear in the drying process of the paint film and exist permanently 13 Pinhole pin hloes is a kind of pathological condition similar to pinhole in the use of acupuncture 14 Wrinkling: how many regular wrinkles in the form of small amplitude ripples are present in the paint film, which can be as deep as part or all of the film thickness 15 Orange skin paint film has the appearance of orange skin 16 During the drying process of whitening glossy coating, the film sometimes appears milky white 17 When the sags; curtains coating is applied on the vertical surface, due to its poor resistance to sags or improper application, too thick paint film and other reasons, the right wet paint film moves downward to form an uneven coating with thick lower edge of various shapes 18 Brush mark a ridge like stripe left on the dry paint film after brushing This is due to the paint drying too fast, viscosity is too large, the paint brush is too rough and hard, the brush method is not appropriate and other reasons that the paint film can not flow flat 19 There are still some small round pits with different sizes and distributions in the film after drying 20 The thick edge fat edge coating is piled up on the edge of the painted surface and presents ridge like protrusion, which makes the edge of the dry film too thick 21 Undercut lifting when applying the same or different coating on the dry paint film, the dry film under the coating will soften, bulge or separate from the substrate during the coating application or drying period (usually appearance such as wrinkling) 22 Color bleeding refers to the diffusion of colored materials from the lower layer (substrate or paint film) into and through the upper layer of the paint film, so that the paint film presents unwanted color or color change 23 After the film is dried, there are irregular convex particles on the whole or partial surface 24 Dirt retention: the phenomenon of dust particles on the surface of dry paint film 25 Loss of gloss
