Date2023-08-25 14:38:30 Hits: CRM

Paper production is a complex process that requires a perfect combination of raw materials and production processes. An important part of this process is choosing the right chemicals for each type of paper to ensure the best quality. This not only affects the characteristics of the paper and enhances the efficiency of the paper machine but also contributes to environmental protection. After years of work and receiving many sharing by our customers, we -

- would like to share some effective ways for a paper manufacturing business to choose the right chemicals:


1. Understand Each Type of Paper:

Before selecting chemicals, you need to identify and understand each type of paper you will produce. There are different types of paper such as Notebook paper, Testliner paper, Medium paper, Printing paper, Packaging paper, etc… Each type of paper has different characteristics and applications. Important parameters like paper thickness, grammage, smoothness, tensile strength, water absorption, opacity, etc., need to be clearly defined.


2. Chemical Technical Standards:

Depending on the type of paper, businesses need to select chemicals with appropriate technical standards. For example, to improve water resistance in packaging paper, you need to use surface waterproofing chemicals during production. Or in the case of printing paper, you should use suitable chemicals to enhance paper smoothness to ensure the best print quality.


3. Compatibility with the Production Process:

Chemical selection must be compatible with your business's paper production process. This includes good solubility, reactivity, and compatibility with other components in the production process. Be sure to choose correctly to avoid hindrance or negative impacts on the paper machine's performance.


4. Environmental Protection Effectiveness:

Chemical choices must ensure sustainability and not harm the environment. Chemicals should be selected based on their ease of recycling and biodegradability. Environmental consideration not only helps businesses comply with environmental regulations but also provides a competitive advantage in an environmentally conscious market.


5. Testing and Evaluation:

Before applying chemicals in mass production, the testing and evaluation process is crucial. Businesses should conduct small-scale tests to ensure the effectiveness and feasibility of the chemicals. This testing helps determine whether the chemicals meet technical and quality requirements.


6. Regular Adjustments:

Paper production is a complex process that requires regular adjustments. Businesses should regularly evaluate the effectiveness of the chemicals in use and make process improvements when necessary. Collaborating with experts and chemical suppliers can help businesses maintain and improve product quality.


7. Employee Training:

Ensure that employees involved in the paper production process are trained in the use and handling of chemicals. Knowledge of how each type of chemical works and how to handle chemical-related incidents is vital for ensuring a safe and efficient production process.


Choosing the right chemicals for each type of paper in the production process is a critical factor in ensuring the best product quality and optimizing the production process. Businesses need to have a clear understanding of each type of paper, its characteristics, and its intended use in order to select the appropriate chemicals. Below are some commonly used chemicals in the paper production process:


- Dry strength agent: It helps to improve the paper dry strength, breaking length, bursting strength, RCT, peel strength and etc. It also improve the retention of fillers and paper fibers and water filtration. It is widely used in the production of package paper, cultural paper, tissues paper and etc.


- Sizing agent: Improve water resistance, brightness, and paper surface smoothness, reduce paper yellowing, and decrease paper brittleness. It can be used in the sizing process of writing paper, offset printing paper, cardboard paper, corrugated paper,  xerographic paper, copperplate base paper and etc.



- Defoaming agent: Compatible with the foam-forming environment, with rapid defoaming speed and excellent bubble elimination performance; 


- Retention aid agent:  has excellent retention of fine fibers and fillers. It can keep the wet end chemical conditions stable, improve the paper uniformity and paper physical properties.  It is used in the production process of writing and printing, newsprint, double offset paper, mechanical pulp paper and linerboard, relief paper, and corrugated paper.
