    厂家揭示环氧地坪漆针孔与缩孔现象及原因

    2018-10-19 10:03:44 无锡盛发地坪科技有限公司 阅读

    针孔:象征及原由解析针孔是指涂膜口头被针尖刺过的小孔,一概皮革毛孔,孔径穷的也有几毫米米.鉴于清漆精制不良,含有杂质;颜料分散不均匀;涂料口头张力穷,薪度高流动性差气泡释放性差;涂料中溶剂挥发快,且用量较多;涂料永久间搅拌变为无数微细气泡;漆基互溶性差,随遭遇温度下落而局部析出或私度上去,均易产生针孔.

    Pinholes: Symbolic and origin analysis pinholes refer to the film oral needle pierced by the small pores, all leather pores, pore size is also a few millimeters poor. In view of the poor refinement of varnish, containing impurities; uneven dispersion of pigments; poor oral tension of paint, poor pay fluidity poor bubble release; paint solvent volatilization, and the amount of more; paint eternal; After a long time stirring into numerous micro-bubbles; Lacquer-based poor mutual solubility, with the encounter of temperature drops and local precipitation or upward, easy to produce pinholes.

    措施掌握施工用涂料的乳度和施工技术;斡旋涂料配方和稀释剂,涂膜喷涂不当太厚;小心施工遭遇湿度不当太穷或喷涂时不应有水分带人涂膜中.

    Measures should be taken to master the emulsiveness and construction technology of the coatings for construction, formulation and diluent of the coatings, improper and too thick film spraying, and caution should not be taken into the film when the humidity is too poor or when spraying.

    缩孔:象征及原由解析当涂料口头张力和底材口头相差穷时,易变为涂料对底材润泽性不良,交锋角变穷,使涂料有保留滴状目标而暴露出被涂面,孔径穷小平常在0.1--2mm.十分是清漆和颜料少的色漆,较简易出现这一缺少,且不简易修缮.

    Shrinkage Pore: Symbol and reason analysis When the oral tension of the coating and the substrate oral poor, easy to change into the coating on the substrate wettability, poor angle, so that the coating has retained dropwise object and exposed the surface, pore size is usually 0.1-2 mm. Very few varnishes and pigments are colored paint, relatively simple to appear this lack, and not easy to repair.

    产生如此象征有涂料自身原由,如涂料口头张力太穷,流动性差,变为润泽不良和气泡释放性差;涂料中混入油污如收缩气氛的油水混人涂料中,底层涂料含有硅油类助剂等;也有底材口头原由,如底层口头有油污或水时变为涂膜润泽不良;腻滑的旧漆膜也简易使涂膜润泽不良;基底口头张力太低出现润泽不良;此外,施工遭遇气氛污浊,湿膜被水、油和其它喷溅物所玷辱均均可变为缩孔.

    Such symbols are caused by the paint itself, such as poor oral tension, poor fluidity, poor wetting and poor bubble release; paint mixed with oil dirt such as shrinkage atmosphere of oil-water mixed coating, the underlying coating contains silicone oil additives; there are also oral reasons for the substrate, such as the underlying oral oil dirt or water when the film does not become wet. Good; greasy old paint film is also easy to make the film wet bad; the base oral tension is too low appear wet bad; in addition, the construction encountered a dirty atmosphere, wet film by water, oil and other splashes are insulted can be reduced to shrinkage.

    措施做好基层进,一步办理就业不得有污物;斡旋涂料品种和配方;小心施工外围遭遇;口头腻滑的旧漆膜赐与合适打磨除掉低极性表层.

    Measures to do a good job at the grass-roots level, further employment must not have dirt; mediate the variety and formula of paint; careful construction of the periphery encounter; oral greasy old paint film given appropriate grinding to remove the low polarity layer.
