    It is suggested that the paper coating is a mixed system composed of a variety of inorganic substances and polymers with different structures, and its performance is an important factor to determine the final product quality and coating process of coated paper

    In the research and evaluation of paper coating performance, the rheological property of coating is considered to be the most important parameter in coating operation

    The coating must have a proper low shear viscosity, which is too small, which may lead to difficulty in feeding and missed coating; the viscosity is too large, which increases energy consumption, and is not conducive to gravity filtration and dehydration of the coating

    In the coating process, the paper coating generally presents "shear thinning & rdqu Which is the price of Dajin diatom mud Recommended brief introduction: which is the price of Dajin diatom mud? How to buy genuine diatom mud? Guangdong diatom mud agent suggests placing a basin of cold water in the air conditioning room, so that the diatom mud wall can breathe effectively

    The feature of the breathing wall is obvious

    When the indoor air is dry, the diatom mud wall will release the absorbed water quickly Put it out to help regulate the indoor dry humidity

    It is suggested to place a basin of cold water in the air conditioning room, so that the wall of diatom mud can breathe effectively

    The feature of the wall that can breathe is obvious

    When the indoor air is relatively dry, the wall of diatom mud will absorb the water Coating House News: paper coating is a mixed system composed of a variety of inorganic substances and polymers with different structures

    Its performance is an important factor that determines the final product quality and coating process of coated paper

    In the research and evaluation of paper coating performance, the rheological property of coating is considered to be the most important parameter in coating operation

    The coating must have a proper low shear viscosity, which is too small, which may lead to difficulty in feeding and missed coating; the viscosity is too large, which increases energy consumption, and is not conducive to gravity filtration and dehydration of the coating

    In the coating process, the paper coating generally presents the property of "shear thinning"

    It seems that once shear expansion occurs, the practical solid content of the coating mixture and the practical speed of the coater have reached the upper limit

    The rheological properties of paper coatings can not only be used to evaluate the advantages and disadvantages of different formulations, but also provide the direction of research and development, which is conducive to improving the technical content and level of coatings

    Paper coating is active in all fields of life

    First, the traditional waterproof paper coating paper box is coated with wax

    The paper board after being coated with wax will certainly affect the color of paper

    The gray style is not so colorful, which will affect the final packaging style

    In addition, wax spraying must increase the weight of cartons and affect the recovery

    The use of water-based coating, not only coating less, and basic does not affect the ability to reprint cartons and cohesiveness, so that our cartons beautiful and strong

    Some of the waterproof coating paper can be made into water tanks, which can keep goldfish for 7 days

    The cartons are still solid and water tight

    2、 Corrugated reinforced coating is a new application field of waterborne paper coating

    In foreign countries, most of the corrugated boxes are single Leng, but at present in China, most of them use multi Leng cardboard to improve the strength of the box

    With the corrugated reinforced coating, we can not only use low gram weight paper, but also reduce the number of cardboard

    The strengthening degree of corrugated reinforced coating is related to the type of paper and fiber properties
