Coating knowledge: identify the quality of ripe tung oil

Core tip: as for the problem of whether there are impurities, let us know a way: first find a clean white paper, the thinner the better, so the effect is more obvious Dip a little cooked tung oil with your fingers, apply it to the white paper, spread it evenly, let the paper eat the tung oil, and spread it on both sides of the white paper, with the area as wide as possible Place in the shade and air dry naturally When it is completely dry, the white paper without impurities is applied, which has a soft hand feel and strong toughness; on the contrary, it is brittle and easy to crack The white paper can also be ignited After burning, if there is only tung oil flavor, there will be no impurities; if there is other pungent taste, ha ha ~ ~ ~ please Application scope and advantages of roller ceramic coating Recommended introduction: the surface of ceramic rubber plate used for roller ceramic coating is cast into durable rubber plate by hundreds of independent small ceramic pieces Each ceramic piece has raised characteristics Under general conveyor belt pressure, thousands of unique cast bumps can produce positive traction, prevent slipping and extend the service life of conveyor belt roller At the same time, the bottom layer adopts high-quality rubber, which has strong elasticity and can play a good impact resistance role The scope of application of roller ceramic coating is one three six 83857180 (the same as V) 1 Roller coating in extremely harsh working environment 2 The belt joint is not suitable for fixing with iron buckle; 3 It is suitable for leather Paint Home News: as for the problem of whether there are any impurities, let us know a way: first find a clean white paper, the thinner the better, so the effect is more obvious Dip a little cooked tung oil with your fingers, apply it to the white paper, spread it evenly, let the paper eat the tung oil, and spread it on both sides of the white paper, with the area as wide as possible Place in the shade and air dry naturally When it is completely dry, the white paper without impurities is applied, which has a soft hand feel and strong toughness; on the contrary, it is brittle and easy to crack The white paper can also be ignited After burning, if there is only tung oil flavor, there will be no impurities; if there is other pungent taste, ha ha ~ ~ ~ please use it carefully!! specifically, the color has no fundamental change (including wood products), but after using tung oil, it will appear oil immersed color (take a piece of dry wood and soak it in water) Add one more point: before the tung oil is wiped, the wood that needs to be wiped must be dried After every wipe, wait for the tung oil to be completely dried, and then wipe the second time After each use of cotton cloth, soak it in tung oil for the next use If it is exposed to the air, it will soon dry out It's very hard There's no way to use it next time It's wasted The smell of tung oil is not harmful to human body The key is to see if you can adapt to the smell If you don't like it, you can wear a mask and operate it Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
