Paint knowledge | powder coating quality standard identification method

It is pointed out that powder coating is a new type of solid powder coating, which is solvent-free, pollution-free, recyclable, environmentally friendly, energy and resources saving, labor intensity reducing and mechanical strength of coating film, etc 1 Appearance recognition handle: the hand feels silky smooth, fluffy and fluffy The handle is rough, heavy and heavy Hold a handful of powder in the hand, the smoother the powder is, the better the quality is On the contrary, the rough handle of the powder is heavy and the quality is poor It is not easy to spray, and there is a lot of secondary powder falling, which is a waste Volume: the larger the volume is, the less the filler in the powder coating, the higher the cost and the better the powder quality The smaller the volume is, the higher the filler in the powder coating is Paint knowledge how about Akzo Nobel Powder Coating Recommended introduction: powder coating is a kind of coating with different form from general coating, which is in powder form It is a new type of coating, because of its own advantages and more and more known by people Let's introduce Akzo Nobel Powder coating Akzo Nobel Powder coating is a cost-effective coating solution, which can be applied to different kinds of products After the treatment of static electricity and fire baking, a tough and durable coating surface will be formed, with the least impact on the environment Since the introduction of this technology, powder coating has been able to continue to maintain the Home of coatings: powder coating is a new type of solid powder coating, which is solvent-free, pollution-free, recyclable, environmentally friendly, energy and resources saving, labor intensity reduction and mechanical strength of coating film 1 Appearance recognition handle: the hand feels silky, fluffy, rough, heavy Hold a handful of powder in hand, the smoother the powder is, the better the quality is On the contrary, the rough handle of the powder is heavy, the quality is poor It is not easy to spray, the second time powder falls, and the waste is large Volume: the larger the volume, the less the filler in the powder coating, the higher the cost The better the powder quality The smaller the volume, the higher the filler in the powder coating, the lower the cost The worse the powder quality is For the same carton, look at the large powder volume of that family, that is the good powder The small size of that family, that is the bad powder It is not easy to spray, the more the secondary powder falling, the greater the waste, the less the spraying area, and the higher the use cost Storage time: the good powder can be stored for a long time, and the powder leveling and other effects will not change The poor powder can not be stored for a long time, and the leveling and other effects will change after 3 months The shelf life of normal powder is 12 months at room temperature, and the product quality of low-end raw materials is unstable and easy to deteriorate When the poor raw materials are used to produce powder, the spraying surface will accelerate the pulverization after half a year, Aging, affect the reputation of customers In addition, the powder is not easy to store, resulting in a large waste of powder to customers and a lot of reimbursement 2 The resin content of normal powder by spray area identification method should be about 55-65%, about 20 yuan / kg for resin, and about 2 yuan for filler Some poor powder factories use the resin content below 45% to replenish the inferior powder, increase the filler to reduce the cost and spray surface area Comparison method: two same powder spray products, see which one has more powder spray products, The spraying products of that company are few, and the spraying products are few, which is poor, with high use cost For the users, the spraying area is small, and the use cost is high According to the calculation of 6 square meters per kilogram of powder spraying, one square meter per kilogram of powder spraying is less, which is equivalent to 3-6 yuan per kilogram of powder overpaid by the manufacturers It is recommended that the manufacturers use genuine powder, and carefully calculate their actual use cost 3 The powder with good working efficiency is very easy to spray Spraying 1-3 guns can cover the base material, with less secondary recovery powder and high working efficiency Spraying 3-5 guns can cover the base material, with more secondary recovery powder and low working efficiency The operating personnel can determine the powder loading rate through spraying, with less powder falling At the same time, less products can be produced and more secondary recovery powder can be recovered, Increase the burden of operators, low efficiency 4 In the baking process, the powder with good baking identification method does not produce a large amount of smoke In the baking process, the poor powder has a large amount of smoke The good powder raw material does not produce a large amount of smoke, and some manufacturers fill the raw material with good materials The amount of powder will increase, the square number of spraying will not come out, increasing the use cost, and the same amount of powder will produce fewer products 5 After baking, the powder products with good appearance and luster identification method have fine, full, transparent and strong three-dimensional sense The poor powder products have dim appearance, rigid, foggy, opaque and poor three-dimensional sense The comparison between the two boards shows that the appearance is poor, which affects the reputation of customers and the appearance of products The powder with good luster has good glossiness, It can maintain the relative luster for a long time The effect of poor powder glossiness is good when it is baked out, and it will start to shoot in a few months The powder made of the material with poor glossiness appearance detection can not maintain the long-term glossiness stability, such as shot light, pulverization, paint peeling, etc 6 The powder with good adhesion and aging identification method has strong adhesion and toughness, and can keep non pulverization and aging for several years The poor powder has poor adhesion and is very brittle It will start to age and pulverize from 3 months to half a year after spraying The adhesion and bending will be tested by comparison, and the aging, pulverization, poor adhesion and aging of the product will be observed after several months The product is easy to age, pulverize, rust and shorten the service life of the product, Impact on customer reputation 7 The high temperature identification method can adjust the temperature to 220-230 degrees and keep the temperature for 10-15 minutes The good powder has good temperature and weather resistance After baking at high temperature, the color changes little and the luster changes little Poor powder, poor temperature and weather resistance, serious discoloration and dullness after high temperature baking, this method is particularly effective for detecting outdoor light color powder 8 Environmental protection identification method good powder materials are produced by large factories, environmental protection is guaranteed Poor materials and added recycled powder, there is no way to ensure environmental protection does not exceed the standard for a long time Environmental SGS detection helps to identify the environmental protection quality of powder coating Home of coatings is
