Corrugated carton starch adhesive preparation and selection of two

â– Diversification of additives

According to the above different conditions to choose different characteristics of bridging agents, accelerators, stabilizers and other additives, must be very professional manufacturers can make suitable for different characteristics of carton manufacturers used additives.

Formulation Formula Design to formulate the most suitable glue for the customer according to the different key points above.

â–  The formula can be tested in a day or two, or it can be six months before you can see the average annual efficiency and waste rate.

Market analysis of starch paste (binder) bridging agent

There are many suppliers of bridging agents for starch paste on the market, but most of the products sold are not very effective. Varieties can be roughly divided into two categories: chemical starch (modified starch), also known as amylopectin; petrochemical products, that is, after the use of petrochemical cracked products processed products.

The names sold on the market include bridging agents, additives, stabilizers, water repellents, reinforcing agents, modifiers, cross-linking agents, modifiers, etc. The main functions are to increase the strength of bonding and improve the bonding speed. , improve the cardboard strength and waterproof (the so-called waterproof is actually water resistance).

How to choose the supplier correctly

The correct selection of suppliers must pay attention to the following points:

â–  Strong professionalism, have a certain reputation in the market

â– Technical team with strong corrugated cardboard production

â–  Choose the team that can help you solve the problem

The quality of the adhesive is actually determined by the material of the cardboard produced and the adhesive formulation used, together with the professional production technology and other factors in order to truly play a role. Since the main components of the binder are starch and water, some manufacturers claim that the addition of additives can save the amount of starch. The author holds a different opinion on this point of view. The use of adhesives for the bonding of the paperboard must have sufficient starch and appropriate water. After adding the additives, the cost will not be reduced. Because only one or two kinds of materials are added to the original formula, it is impossible to reduce the cost. The so-called cost reduction must be achieved under certain conditions. Such as reducing the amount of glue, increasing the speed, reducing the loss and the cooperation of the operators, etc., only to meet these requirements in order to effectively achieve the purpose of reducing costs in general.

The quality of adhesive additives is not depending on the surface, such as the viscosity of the liquid, or whether the concentration is suitable or not, but it must first be considered whether it is completely soluble in water. If there are particles or strings, then these products The quality is certainly a problem, because in the most important hydrophilic agent does not dissolve in water, how can it strengthen the adhesion? Therefore, the prerequisite for selecting good additives is to be completely soluble in water. Nowadays, there are many kinds of additives in the market, and the general manufacturers cannot directly detect the quality of the mouthpieces, and they are not able to understand them. Therefore, it is only necessary to detect whether they are completely soluble in water, and whether there are sediments after standing for several hours, such as Without sediment, the quality of this product should be good.
