Coating process: Impermeability test

Core tip: under certain conditions, the instrument is used for testing The method is to prepare the waterproof coating according to the proportion, brush it on the glass plate several times (wax the glass plate first), the thickness is 1.5mm, put it in the oven for 7 days, then put it in the oven at 50 ℃ ± 2 ℃ for 24 hours, take it out and put it in the oven for 3 hours, and do the water impermeability test, the water impermeability is 0.3MPa It is qualified if there is no leakage within 30 minutes If the conditions are not available, visual inspection can be used to test the waterproof effect The method is to brush the waterproof coating on the non-woven fabric in 4-6 times, and after drying (about 24 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: under certain conditions, use the instrument to test The method is to mix the waterproof paint according to the proportion, brush it on the glass plate several times (wax the glass plate first), the thickness is 1.5mm, put it in the oven for 7 days, then put it in the oven at 50 ℃ ± 2 ℃ for 24 hours, take it out and put it in the oven for 3 hours to do the water-proof test, the water-proof is 0.3MPa It is qualified if there is no leakage within 30 minutes If the conditions are not met, visual inspection can be used to detect the waterproof effect The method is to paint the waterproof coating on the non-woven fabric in 4-6 times After drying out (about 24 hours), the film thickness is 1.2-1.5mm, which is made into a slow box shape and lifted empty, but there is no dead angle Then add 1% alkali water into the box, and it is qualified if there is no leakage in 24 hours 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,
