Problems solved by technology

If the starch paste is not well controlled, it will easily cause poor cardboard lamination, insufficient compression resistance, exposed pits, warping, and high scrap rate
Starch paste is a pasting method in the prior art, including one-barrel and two-barrel pasting methods. One-barrel is a one-time molding in a barrel. This molding method is difficult to form ungelatinized starch granules suspended until they are completely The effect in the gelatinized paste mother, so its sticking performance is poor, and the two-barrel paste method can form a suspension effect, but the two-barrel type of equipment is more, troublesome to operate, and not easy to control

Embodiment Construction

[0014] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0015] A paste making process is carried out in the following steps,

[0016] (1) Warm water with 455 parts by weight, starch with 50 parts by weight, caustic soda with 9 parts by weight and borax with 0.5 parts by weight are mixed, stirred and sheared for 8-10 minutes. Under the action of dissolving in water and releasing heat, the heat of the mixture quickly reaches the temperature of starch gelatinization at 60°C. Stirring for 8-10 minutes is to fully gelatinize and form a completely gelatinized paste mother. It is also beneficial to gradually reduce the temperature and carry out Lower process;

[0017] (2) Pour 630 parts by weight of water, 300 parts by weight of starch and 5 parts by weight of borax into the mixture obtained in step (1), and...

Abstract

The invention provides a paste preparation technique, relating to the technical field of starch paste. The paste preparation technique is characterized by comprising the following steps: (1) mixing, stirring and shearing 455 parts by weight of warm water, 50 parts by weight of starch, 9 parts by weight of alkali and 0.5 part by weight of borax for 8-10 minutes; (2) pouring 630 parts by weight of water, 300 parts by weight of starch and 5 parts by weight of borax into the mixture obtained in the step, and mixing and stirring for 8-12 minutes; and (3) pouring 14 parts by weight of binding agent into the mixture obtained in the step (2), and thoroughly mixing. The invention simple to operate, and has the advantages of less equipment, lower production cost, favorable paste preparation effect and sufficient paste viscosity.

Description

Technical field: [0001] The invention relates to the technical field of starch paste, in particular to a paste making process. Background technique: [0002] Starch paste is the most important auxiliary material in the production process of corrugated cardboard and carton. Almost all physical indicators of corrugated cardboard and carton are related to starch paste. The quality of starch paste directly affects the quality of production. High-quality starch paste can make the cardboard stick firmly, have good hardness, high strength, smooth cardboard, and good moisture resistance. If the starch paste is not well controlled, it is easy to cause poor lamination of cardboard, insufficient compression resistance, exposed pits, warping, and high scrap rate. Starch paste is a pasting method in the prior art, including one-barrel and two-barrel pasting methods. One-barrel is a one-time molding in a barrel. This molding method is difficult to form ungelatinized starch granules suspe...
