1. Observe changes in water and water. In the evening patrol, when the odor of the fish pond smelled or the handle was immersed in the pool water, the hands were stained with a layer of mud. The above two conditions occurred, indicating that the water quality had deteriorated. Lime was used to disinfect and purify the water immediately. . The specific method is: 30 kg of lime per acre is applied to a pond with a depth of 4 meters, and 15 kg of lime is applied to a pond with a depth of about 2 meters. At the time of application, the lime was added to the water and the pond was split into two halves. After half of the splash, the water quality became clear and the other half poured.
2. Pay attention to sudden rainfall weather. During the hot season, there is a sudden rainfall of water. The upper and lower levels of water exchange will inevitably occur on that night, which may lead to dead fish due to lack of oxygen. Therefore, feeding must be stopped in the afternoon and the oxygen must be turned on in the early morning.
â… Product Composition: polydadmac
â…¡ Product Properties
The appearance of this product is colorless to pale yellow viscous liquid. It is soluble in water. It has goodhydrolyticstability and high adaptability to PH value changes. It`s safe and non-toxic. Its freezing point is about -2.8℃, specific gravity is about 1.04/cm3 and decomposition temperature is 280-300℃. It`s polymeride AKD maturing agent of high charge density. Emulsion provides strong cationic component promotive and protective agent and promotes curing effect. This product is added directly into the synthesis process of intermediates or added a certain ratio in emulsion. This product can be added more in the papermaking system with heavier anionic trash, as the pulp potential equilibrium to play a dual role of sizing enhancement and forcing ripening.
III. Quality indicators;
Appearance: colorless to faint yellow thick liquid Solid content: 40±1%
PH value: 4.0~7.0 viscosity (mpa.s, 25℃): 7000-12000
IV. Application:
This product is applied in alkaline sizing system of AKD (Alkyl Ketene Dimer) to restrict largely the hydrolysis and migration aptitude of AKD. [The third generation" AKD is mainly used for the making of multipurpose duplicating paper filled by precipitated calcium carbonate. 60% cationic polymer can adhere to the fiber after the paper containing cationic polymer being reused, by which enhance hydrophobicity of the paper. Added to waste paper deinking agent, its cationic hydrophilic group adheres to ink particles easily, especially for hydrophobic aniline ink. After flotation, the whiteness of pulp increased. This product is also applied as cationic surfactant in pitch control agent for pulping.
