消光粉的不同处理方法表现出来的不同效果
Different effects of different treatments of matting powder
消光粉是由聚丙烯酰胺,成膜物原料制成的新型皮革补伤消光剂。用于深色、浅色表面伤残,深伤残皮革粒面修补,其遮盖力强,补伤效果好。使用时不必与其它软性皮化材料配方,可直接用于"刷涂"或"点涂"修补,简化了原有的使用方法。制造工艺简单,原料易得,易形成批量生产和推广应用,满足皮革工业的需要。可分为油性消光粉和水性消光粉。广泛应用于乳胶漆,内外墙涂料,醇酸树脂漆和聚酯漆等多种涂料体系中。应用涂料、油漆中,能均衡的控制涂膜表面光泽,增加涂膜的耐磨性和抗划痕性,去湿、除臭、净化空气,隔音、防水和隔热、通透性。
Matting powder is a new type of leather matting agent made from polyacrylamide and film forming material. It is used for repairing the grains of dark and light-colored surface disabled and deeply disabled leather. It has strong covering power and good repairing effect. It can be directly used for "brushing" or "point coating" repairing without any formula of other soft leather materials, thus simplifying the original use method. The manufacturing process is simple, the raw materials are easy to obtain, and it is easy to form batch production and popularize application to meet the needs of leather industry. It can be divided into oily matting powder and water matting powder. It is widely used in latex paints, interior and exterior wall coatings, alkyd resin paints and polyester coatings. In the application of coatings and paints, the surface gloss of the film can be controlled equally, the abrasion resistance and scratch resistance of the film can be increased, dehumidification, deodorization, air purification, sound insulation, waterproof, heat insulation and permeability can be increased.
对于常规消光粉,大家都知道消光剂的平均粒径越大,消光效率就越高。但如颗粒太大了,会导致漆膜表面太粗糙,影响手感和外观。
As for the conventional matting powder, we all know that the larger the average particle size of the matting agent, the higher the extinction efficiency. However, if the particles are too large, the surface of the paint film will be too rough, which will affect the feel and appearance.
选择孔隙率(孔容)较高的产品。孔隙率越大,单位重量粉料含量就会越高,消光性能就越好。
Choose products with higher porosity (Kong Rong). The greater the porosity, the higher the powder content per unit weight and the better the extinction performance.
消光剂的平均粒径越小,漆膜的透明性就越好,但相应消光效率也会降低,需要指出的是细粉含量太高,对透明度会产生负面影响。
The smaller the average particle size of the matting agent, the better the transparency of the film, but the corresponding matting efficiency will also be reduced. It should be pointed out that the high content of fine powder will have a negative impact on the transparency.
其实,表面处理效果也会影响消光粉的其他作用。
In fact, the effect of surface treatment will also affect other functions of matting powder.
有机处理的消光粉:防沉性能会好一些。消光剂随着涂料存放时间的延长,都会在一定程度上出现分层与沉淀但是这个只是短时间的,时间太长的话,还是会沉淀。
Organic treated matting powder: anti sinking performance will be better. With the prolongation of the coating storage time, the matting agent will be stratified and precipitated to a certain extent, but this is only a short time, if the time is too long, or will precipitate.
蜡处理的消光粉:一般利用于清漆当中,由于清漆中不方便加白炭黑,所以清漆中添加蜡处理的消光粉,防沉淀、结硬块,并能与溶剂型涂料体系很好地相容,不会产生重浮附着力问题,相反还增加漆膜抗划伤性,增强漆膜滑度,不足之处是经蜡处理的白炭黑消光剂消光性稍差,漆膜透光度略差。
Wax-treated matting powder: generally used in varnishes, because it is not convenient to add white carbon black in varnishes, so varnishes with wax-treated matting powder, anti-precipitation, agglomeration, and can be well compatible with solvent-based paint system, will not produce heavy floating adhesion problems, on the contrary, also increase the scratch resistance of paint film, enhance paint film slippery The deficiency is that the light extinction of the white carbon black matting agent is slightly worse, and the transmittance of the film is slightly worse.
不经过处理的,价格便宜,消光程度好。
Without treatment, the price is low and the extinction is good.
