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.

Everything has a life cycle; the bearing also has its own service life. To extend its service life; this requires that the repairer knows the corresponding skill requirements of SKF bearings when the bearing is worn; and the layout of SKF bearings and their parts, Process and data features; otherwise it is difficult to ensure that SKF bearing repair has the role of meeting the demand. /*250*250 was created on 2017/12/25*/ var cpro_id = 'u3171089';
First, the economic benefits of SKF bearing repair in general; SKF bearings are small; large quantities; the price of a single SKF bearing is high; or the layout of SKF bearings is simple. The scale is large; the repair cost is relatively low; the higher the economic efficiency .
Others; monitor the working condition of SKF bearings; plan to repair before SKF bearing failure; can get twice the result with half the effort; follow reasonable process; use efficient repair equipment and things; and obtain professional skf bearing factory Assistance; all contribute to the economic benefits.
Second, the advantages of cooperation with professional SKF bearing company users in the repair of SKF bearings; if you can get the cooperation of professional SKF bearing company; will be able to get the following advantages:
(1) the skill requirements of each process that can be clearly repaired; and how to ensure the overall quality of the repaired SKF bearings;
(2) Ability to use many of the specialized experiences of professional SKF bearing plants; these experiences can reach process requirements reliably, efficiently, and economically.
(3) It is able to order the molds of the professional SKF bearing company; it can be used for repairing affairs; it can be economical and saves a lot of troubles.
(4) Can order from professional SKF bearing company such as cage; rollover, rivet and other accessories; can make the repairing work simple and convenient.
