Core tip: most adhesives are made of high molecular materials Some of them need to be cured by chemical reaction or physical action These will happen slowly in the storage process of adhesives Therefore, adhesives have a certain storage period, which is related to storage conditions, such as humidity, temperature, ventilation, etc In order to ensure that the performance of the adhesive is basically unchanged within the specified period, it is necessary to pay close attention to the method of keeping the adhesive For different kinds of adhesives, due to their different properties, the storage conditions are different The precautions for the storage of several commonly used adhesives are as follows: 1) epoxy resin adhesives should be ventilated, dried 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: most adhesives take polymer as soil mass, some need to add certain solvent, and rely on chemical reaction or physical action to achieve curing These will occur slowly in the storage process of adhesives Therefore, adhesives have a certain storage period, which is related to storage conditions, such as humidity, temperature, ventilation, etc In order to ensure that the performance of the adhesive is basically unchanged within the specified period, it is necessary to pay close attention to the method of keeping the adhesive For different kinds of adhesives, due to their different properties, the storage conditions are different The precautions for storage of several commonly used adhesives are as follows: 1) epoxy resin adhesives shall be stored in ventilated, dry, cool and room temperature environment for a period of six months to one year 2) The phenolic resin adhesive shall be stored in a closed container in a cool place away from the fire for a period of six months to one year 3) Polyisocyanate solution should be put into brown bottles, stored in dark and low temperature, not in metal containers, not in rubber and cork bottles And strictly prevent the water from entering, otherwise the polymerization will occur; the prepolymer polyurethane adhesive should not be stored at low temperature to prevent condensation, the storage period of component A is 2 years, and the components should be moisture-proof, and avoid contact with water or other substances containing active hydrogen, the period is half a year to one year 4) The storage temperature of urea formaldehyde resin adhesive should be as low as possible If 5% methanol is added, the storage stability will be improved 5) The container of chloroprene rubber adhesive has good sealing property It can be stored at room temperature, not too high (> 30 ℃) or too low (< 5 ℃), far away from fire source The storage period is 3-6 months 6) A-cyanoacrylate adhesive shall be stored in a sealed, low temperature, dry, dark and cool place for one year The storage period of glass bottle is longer than that of plastic bottle 7) The anaerobic adhesive shall be stored in a cool and dark place for half a year The packaging container shall be made of polyethylene Iron containers shall not be used and shall not be filled to avoid deterioration and failure of polymerization due to solid isolation of air 8) The SGA adhesive shall be stored in a sealed manner The two components shall be isolated and placed in a cool, ventilated, low temperature and dry place for a period of six months to one year 9) polyvinyl acetate emulsion (white glue) is packed in containers of glass, ceramics and plastics The storage temperature is between 5 and 30C, and the storage period is 1 years 10) The hot-melt adhesive shall be stored in the dark, heat insulation and room temperature 11) Inorganic adhesives shall be stored in a sealed manner to prevent moisture absorption from affecting their use 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,
