Modified plant fiber material type glass moldproof parting powder

Abstract

The invention discloses a modified plant fiber material type glass moldproof parting powder which is prepared by carrying out surface modification on plant fiber pulverized substances. The preparation method comprises the following steps: screening plant fiber pulverized substances, mixing with a modifier solution, standing, treating under the absolute pressure of 100-500kPa at the temperature of 0-300 DEG C for 0.1-48 hours, and finally, directly drying to obtain the modified plant fiber material type glass moldproof parting powder. The modifier is selected from one or mixture of organic acids, inorganic acids or acid salts. The moldproof parting powder has the advantages of favorable flowability, adsorptivity and natural degradability, can postpone the glass from becoming moldy, basically does not generate flying ash, and is clean and convenient. The glass using the product can be easily cleaned after long-term storage, and can not influence the subsequent processing and use of the glass.

Description

technical field [0001] The invention belongs to the field of fine chemicals, and in particular relates to an anti-mildew isolation powder sprayed on the surface of glass and a preparation method thereof. Background technique [0002] In the glass manufacturing industry, in order to avoid the huge losses suffered by the erosion and bonding of the glass surface, the most popular method in the world is to spray glass anti-mildew isolation powder on the glass surface. [0003] In the past, anti-mildew and isolation powders were simply mixed with solid acidic anti-mildew materials and polymers. Due to the differences in the density and surface physical properties of the acid materials and polymers, the mixing uniformity of the anti-mildew and isolation powder products was poor, and each Components are prone to separation during subsequent packaging, transportation, use, etc., resulting in local functional imbalance. Due to this imbalance, it is difficult for this type of anti-mo...

Problems solved by technology

However, the current use of coconut shell powder is limited to isolation and does not have anti-mildew ability. It needs to be supplemented with anti-mildew liquid, anti-mildew powder and other anti-mildew measures, which cannot be used alone

In addition, the current crushed plant fibers such as coconut shell powder have poor adsorption capacity on the glass surface, low use efficiency, serious waste, and are not suitable for vertical stacking packaging.

Due to the biological characteristics of plant fibers, under water absorption or humid conditions, biological mildew will occur, resulting in glass contamination
