Coating process: Determination of continuous hydrophilicity of coating

Core tips: 1 Dry wet cycle (°) ① Sample preparation: White embryo is made of normal coating material and processed by normal coating technology ② The length of the coating product test piece is more than 250mm, the width is more than 150 mm, and the thickness is not less than 12mm Each test piece shall be made of at least 3 pieces ③ Take three samples and hang them on the dry and wet circulator for experimental test (soak for 2min, blow dry for 6min as a cycle) ④ Take out and dry after 300 cycles ⑤ Use the contact angle tester to measure the contact angle value of the sample plate, take three points for average 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 Paint Home News: 1 Dry and wet cycle (° 1) sample production: use normal paint product materials to make white embryo, and use normal paint process to make ② The length of the coating product test piece is more than 250mm, the width is more than 150 mm, and the thickness is not less than 12mm Each test piece shall be made of at least 3 pieces ③ Take three samples, hang them on the dry and wet circulator for experimental test (soak for 2min, blow dry for 6min as a cycle) ④ take them out for drying after 300 cycles ⑤ Measure the contact angle of the sample plate with the contact angle tester, and take three points for the average value 2 Wash with water (1) take three samples of coating products, immerse them in flowing tap water (flow rate 1-3 L / min) for 100 hours, and then take them out for drying ② measure the contact angle of the sample plate with contact angle tester, and take three points for average value 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,
