2. Characteristics of HM-2650B

HM-2650B has ultra-high molecular weight due to the latest synthesis method of our company. It performs better in water filtration and retention than the general bridging amphoteric dry strength agent. It is especially suitable for the system with high degree of closed circulation of white water and low amount of aluminum sulfate. It can improve the strength of paperboard and improve the papermaking performance and fiber retention at the same time. It is especially suitable for the production of high-grade box board paper with waste paper as raw material.

The characteristics of hm-2650b are summarized as follows:

1) High speed paper machine suitable for closed circulation of high white water;

2) This machine is suitable for producing high-grade paper with pulp with high content of fine fiber.

3) This product has the characteristics of high filtration and high retention

3. Usage and precautions of HM-2650B

1) When diluting the product, please use clean water. Do not use unclean water such as white water. The dilution ratio is generally about 15 times. The product can be added to the slurry only after it is fully and evenly dispersed by stirring.

2) The addition position shall be selected where it can be fully mixed with the slurry. Generally, it is added in the batching tank or high-level tank.

3) Please use FRP, PVC, PE and other plastics or stainless steel for the materials of product storage tank, dilution tank and piping. Iron products will corrode and increase the viscosity of the product. Do not use it.

4) Do not mix with other chemicals.

5) The storage period of the product is 6 months. For expired products, there may be quality degradation. Please pay attention.

As the product is acidic, please rinse it with tap water if it comes into contact with skin. In case of contact with eyes, rinse with tap water and ask a doctor for examination. If you drink by mistake, spit it out and send it to the hospital for examination
