Key tips: 1 Coating formula: (1) Formula of compound glue: ① Ch-602 glue: 35kg of ch-602 glue, 315kg of water, 350kg of glue ② Polyvinyl alcohol glue: Raw material consumption / kg polyvinyl alcohol 5 borax 4.5 water added to 170 ③ Compound glue: The amount of raw material is /kgCH-602 rubber powder glue, 350 borax modified polyvinyl alcohol glue (about 5%) 170 polyvinyl acetate emulsion (solid content 45%) 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 House News: 1 Paint formula: (1) formula of composite glue: ① ch-602 powder glue: ch-602 glue 35kg, water 315kg, can get glue 350kg (II) polyvinyl alcohol glue: raw material dosage /kg polyvinyl alcohol 5 borax 4.5 water to 170 170 compound glue: raw material dosage /kg CH-602 glue powder glue 350 borax modified polyvinyl alcohol glue (concentration 5%) 170 polyvinyl acetate emulsion (solid content more than 45%) 0.5 CH-718C thickening agent thickener 1 water to 700 (2) coating formula: raw material dosage /kg compound glue 2 Shengli powder 250 light calcium 50 talcum powder 50 ultramarine 5-7 tributyl phosphate 0.2 water is added to 1000 2 Production equipment: (1) a set of glue pot (capacity 500L), mixer power 2-3kw, rotating speed 60-80 R / min, self prepared heating equipment (2) One set of paint mixer with cylinder capacity of 1000-1500l, mixer power of 5-7.5kw and adjustable speed (3) One grinder (4) Two turnover pull cylinders (capacity 500L, 1000L) (5) other commonly used small appliances 3 Production process: (1) preparation of ch-602 rubber powder glue According to the formula, first take 315kg of water and put it into a 500L pull cylinder, start the mixer (rotating speed: 300r / min), slowly sprinkle 35kg of ch-602 rubber powder into the agitated water, mix it for more than 15min, make the rubber powder completely dissolve, and turn it into a transparent glue without dissolving rubber particles If there are still unmelted micelles, they can be left overnight, and they can be completely melted the next day (and then properly stirred) (2) Preparation of PVA glue modified by borax Dissolve the polyvinyl alcohol into a glue with a concentration of about 5% After all the polyvinyl alcohol is dissolved, when the glue is cooled to 80 ℃, keep warm At this time, dissolve 4.5kg of borax into a 10% aqueous solution with boiling water, mix the PVA glue with a mixer, and then slowly (in a fine flow way) add the borax into the polyglycol glue, and keep the temperature at 80 ℃ for 30min Polyvinyl alcohol was complexed to produce good water resistance, and the appearance concentration of glue was also improved After 30 minutes of heat preservation, the glue can be discharged when it drops to room temperature If the weight is insufficient due to water evaporation, add water to make up the weight (3) Preparation of compound glue Add 170kg of borax modified polyvinyl alcohol glue to the pull cylinder of the mixer, start the mixer and rotate it at 300r / min Add polyvinyl acetate emulsion 0.5kg, CH-602 type glue powder glue 350kg, CH-718C type thickening agent thickener colloid solution 51kg, add water 140kg, continue stirring, mix evenly, get compound glue about 700kg, reserve (4) Preparation of coating: ① According to the formula, first add 600kg of composite glue to the pull cylinder of the paint mixer, in addition, use 45kg of water in the formula to dissolve the ultramarine (5-7kg), then filter the ultramarine water into the pull cylinder of the mixer with a 100 mesh screen, start the mixer, rotate the speed of 300r / min, mix evenly, gradually add the multi-functional powder, light calcium and talcum powder (can't be added at one time), fully mix it for about 1H, so as to make it Become a uniform and soft coating ② The coating is fed into the grinder and ground to under 80 μ M ③ Add defoamer to the filtered coating, mix well, fill the barrel, and tighten the end of the barrel to prevent the crust on the surface due to the air entering 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,
