polyvinyl alcohol glue defoaming agent is a specially developed for the foam problem of polyvinyl alcohol glue defoaming agent. Due to uneven glue mixing, mechanical equipment, operation and other reasons easy to lead to a large number of foam. This has a great impact on the firmness of the glue, the quality and the production process. At this time will use the polyvinyl alcohol glue defoaming agent
Polyvinyl alcohol glue defoaming agent is a specially developed for the foam problem of polyvinyl alcohol glue defoaming agent. Due to uneven glue mixing, mechanical equipment, operation and other reasons easy to lead to a large number of foam. This has a great impact on the firmness of the glue, the quality and the production process. At this time will use the polyvinyl alcohol glue defoaming agent.
What is polyvinyl alcohol glue:
Namely white jiao, a kind of chemical synthetic adhesive, is an important adhesive type of the current stamp gum. It is a binder made of polyethylene and aldehydes. Its breaking quality is shallow and thin, with strong adhesion and tide resistance, which was widely adopted by many countries.
Causes of blistering:
1 The air humidity and temperature in the operating environment do not meet the requirements for glue production
Air is brought into the glue mixing or filling process, resulting in bubbling
3 the stirring operation is not standard, resulting in bubbling
Harm of foam:
1 there are bubbles, which will affect the degree of harmony of the product
Too much foam will affect the bonding strength when using adhesive at the end
3 affect the appearance, reduce the customer's trust
4. Slow down the production process and affect the production efficiency
Characteristics of polyvinyl alcohol glue defoaming agent:
1. Strong anti-foaming and anti-foaming power, less dosage, does not affect the basic properties of foaming system
2 good dispersibility, solubility is strong, can dissolve well with the original liquid
3 will not lose the original performance, will not change the original color of the product
4. Strong defoaming ability, fast bubble breaking speed, long bubble suppression without rebound
