    Core tip: mainly through the surface absorption of water to complete dry consolidation or bonding The raw solid starch in the adhesive is gelatinized on the paste line to absorb water The bonding time is a few seconds to a minute Water is gradually absorbed by the surrounding air and paper fibers This traditional adhesive is generally used in the corrugated board production line, which can immediately produce a strong bonding effect In order to achieve satisfactory bonding effect, a slightly viscous suspension emulsion, containing pre gelatinized starch, must be added to the starch and water emulsion This suspension emulsion can make raw starch suspended in water and prevent it from settling; increasing the concentration is easy to be carried on the cots and form the appropriate thickness on the roller Paint knowledge | precautions for wall paint color selection Recommended introduction: when painting the wall, the owner sometimes has difficulty in choosing what color of the wall paint to paint In fact, there is no ugly color in the wall paint, only the disharmonious color matching The use of wall color contains the knowledge of health Too strong color will stimulate people's perception, make people have a sense of fidgety, affect people's mental health Grasp the basic principles of wall color and paint a colorful space 1、 Wall paint color selection notice 1 Light color is generally used for the top surface Light colors make people feel light, dark colors make people feel heavy Usually, the treatment of rooms is from top to bottom, from shallow to deep For example, the ceiling and walls of rooms are white and Paint Home News: mainly through the surface absorption of water to complete dry consolidation or bonding The raw solid starch in the adhesive is gelatinized on the paste line to absorb water The bonding time is a few seconds to a minute Water is gradually absorbed by the surrounding air and paper fibers This traditional adhesive is generally used in the corrugated board production line, which can immediately produce a strong bonding effect In order to achieve satisfactory bonding effect, a slightly viscous suspension emulsion, containing pre gelatinized starch, must be added to the starch and water emulsion This suspension emulsion can make raw starch suspended in water and prevent its precipitation; increasing concentration is easy to be carried on the cots and form paste film on the roller with proper thickness; adjust viscosity so as to make paper fiber suitable wetting initial adhesion; ensure that there is a lot of water around the raw starch molecules, so that starch can expand to the maximum extent and gelatinization when heated Caustic soda must be added to adjust and control the gelatinization temperature of starch to a minimum In order to achieve a satisfactory bonding effect, borax must be added to make raw starch absorb all water available for absorption when heated; to make starch produce proper viscosity and toughness when gelatinized; to play the role of buffer to prevent caustic soda from swelling part of raw starch under the lowest gelatinization temperature 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,
