Coating classification: ash content of coating

Core tip: Introduction: The ash content of the coating refers to the inorganic substance obtained from the calcination of the remaining residue after the sample is burned under the specified conditions, expressed in mass percentage The national standard analysis method is: GB / T 1747-79 coating ash determination method The practical analytical method in the factory is burning method After the sample is completely carbonized in the electric furnace, it is put into the high-temperature furnace for burning and converted into ash, then cooled and weighed Calculation formula: ω (ash) = (M1 / M) × 100% Medium: &om Shenyang steel structure fireproof coating construction expert punde Building Fire Engineering Co., Ltd Recommended introduction: since its establishment, Shenyang punde Construction Fire Engineering Co., Ltd has cultivated a group of professional construction teams with excellent equipment, rich experience and serious responsibility with advanced and scientific management methods and strict engineering quality assurance and after-sales service system It has undertaken a number of fire system installation projects, which has been praised by customers Every idea and special requirement of you will be fully considered by us and fully realized in the construction technology, which will become the cornerstone of our successful long-term development We are looking forward to your invitation, to provide you with quality services and high-quality technical support! All construction coatings have passed ISO9001 Introduction: the ash content of the coating refers to the inorganic substance obtained by calcining the residue after the sample is burned under the specified conditions, expressed as per the mass percentage The national standard analysis method is: GB / T 1747-79 coating ash determination method The practical analytical method in the factory is burning method After the sample is completely carbonized in the electric furnace, it is put into the high-temperature furnace for burning and converted into ash, then cooled and weighed Calculation formula: ω (ash) = (M1 / M) × 100%, where ω (ash) - mass fraction of ash in sample,%; M1 - mass of ash, G; m - mass of sample, G Take the average value of two parallel tests as the measurement result Measurement error: the difference between two parallel results shall not exceed the provisions in the table below The allowable difference of ash content is ω (ash content) /% allowable value /% 0.001 0.002 0.001-0.080 0.003 0.001-0.180 0.007 0.180 0.01 paint home is focused on coating, diatom mud, paint coating, coating technology, fire-resistant coating news information and coating, diatom mud, paint coating, coating technology, fire-resistant coating decoration knowledge and decoration effect map,
