    1. Dry powder add, dosage is 1% of gypsum (Weigh separately, then mix with gypsum powder)
    2. Wet add, dosage is 0.5%--0.8% of gypsum (mix with water, then add into gypsum)

    Besides, dosage has indirect or direct relationship with air permeability, degree of sizing and water absorption of protective paper, specification and varities of gypsum, air humidity, gypsum board molding and drying method, and thickness of board, etc.. It should be mastered flexibly in the production process, and stable and accurate addition quantity should be found through practice.

    Functions and advantages

    1. The gelatinization temperature of acid modified starch is low, which can be adequately gelatinized in the drying process of gypsum board
    2. The formed paste has stable viscosity, good adhesion, stable performance, and ehances interlayer adhesion and breaking strength
    3. Good water resistance, easy to form a transparent film, effectively prevent the gypsum board’s collapse caused by dampness
    4. Our company’s acidized starch is produced with wet production method, which makes it has high purity and stability, and also help save the dosage


    1. Acidized starch is widely used in producing plasterboard without mortar for wall construction, various gypsum board with papersurface
