Briquettes group binder precautions in custody
 Briquettes group binder polymer substance is mostly the soil, some will have to add some solvent, chemical reactions or physical effects rely on to achieve curing, these will slowly take place in the adhesive storage process, so. Adhesive has a certain shelf life, which is the storage conditions, such as humidity, temperature, ventilation and other relevant. To ensure that the adhesive properties within the prescribed period will remain basically unchanged, strict attention to the custody of the binder method it is essential. For the different types of plastic binder, by its nature different storage conditions are not the same.
Now Precautions Introduction of several commonly used as a binder custody;
1, an epoxy adhesive should be ventilated, dry, cool, room temperature storage, for a period of six months to a year.
2, phenolic resin binder should be packed in a sealed container, storage in a cool, away from fire places for a period of six months to l years.
3, polyisocyanate glue should be stored in a brown bottle, dark cold storage, can not use metal containers, can not use rubber and cork stoppers. And to prevent moisture from entering, otherwise it will polymerize deterioration; prepolymer polyurethane adhesives Avoid low temperature storage, to prevent condensation, Group A points can be stored for 2 years, had to pay attention to moisture component, and avoid moisture or other containing active hydrogen exposure to the substance for a period of six months to one year.
4, urea-formaldehyde resin binder storage temperature should be as low as possible. If adding 5% methanol uh improve the storage stability.
5. The containers neoprene adhesive seal better. Stored at room temperature, non-temperature (> 30 ℃) or too low (<5 ℃), away from the fire source. Storage period is from March to June.
6, a- cyanoacrylate adhesives should be in a sealed, cool, dry, dark, cool place to store for a period of 1 year. Glass than plastic bottles containing costumes, long storage period.
7, anaerobic adhesive should be stored in a cool, dark place, storage period of six months, the material should be polyethylene containers, avoid the use of iron containers can not be filled, so as not to cut off the air and solid polymeric deterioration failure.
8, SGA adhesive should be sealed storage, the two components to be isolated, placed in a cool, ventilated, cool, dry place for a period of six months to one year.
9, polyester vinyl acetate emulsion (milky plastic) application of glass, ceramic, plastic containers and packaging, store temperature is 5 ~ 30c, pay attention to antifreeze, storage period of 1 year.
10. The hot melt adhesive should be stored in the dark, insulation, room temperature.
11, an inorganic binder should be stored to prevent moisture absorption affect use.
