What is a Kraft Paper

 

 

Like all paper, Kraft Paper is made from wood which is a renewable natural resource. The paper is made using the Kraft Process which involves converting wood into wood pulp. Lignin and cellulose are the two structural components in wood but due to the fact lignin doesn't make good paper it must be separated from the cellulose using a cooking process. This leaves the wood pulp which is screened to remove large pieces and can then be formed into various paper products.The kraft process if different from standard wood pulping processes because of the way it strips away more lignin, leaving more cellulose which is stronger than lignin and results in stronger paper.

 

Advantages of Kraft Paper for Cooling Pads

Highly absorbent
Wet curtain paper can quickly absorb and retain a large amount of water, providing the basis for evaporation and cooling.

 

High evaporation cooling efficiency
water forms a water film on the surface of the cooling pad, and when the air passes through, the water in the water film absorbs the heat in the air and evaporates, thus significantly reducing the air temperature. The cooling efficiency of this process can reach more than 80%.

Strong durability

Paper cooling pad with high water resistance, mildew resistance and other characteristics, long service life.

Environmental protection and energy saving

The cooling pad cooling system uses water as the refrigerant, which is pollution-free to the environment and more energy saving than the traditional air conditioning system.

Easy installation and maintenance

The wet curtain paper system is relatively simple and easy to install and maintain.

Applications for Kraft Paper of cooling pads
 

Poultry and animal husbandry

Such as chicken farms, pig farms, cattle farms, etc., used to regulate the temperature and humidity of the breeding environment.

Greenhouse and horticulture

Such as vegetable storage, seed houses, flower planting, grass mushroom planting, etc., to help control the temperature and humidity in the greenhouse.

Industrial cooling

Suitable for factory cooling and ventilation, industrial humidification, entertainment venues, precoolers, air handling units and other scenes.

Commercial and retail Spaces

Commercial and retail Spaces such as malls, shopping centers, large retail stores, etc. can be used to reduce indoor temperatures and improve customer comfort.

Public facilities and activity venues

Such as stadiums, exhibition centers, theaters, etc., can be used as a cost-effective way to cool down during large-scale events in the summer.

Educational institutions

Schools, universities and other educational institutions can use cooling pad systems to reduce the temperature of classrooms and libraries in the summer.

 

How to Properly Store and Maintain Kraft paper to Ensure Its Long-term Performance
 

Selection and preparation of storage environment
As a high-quality paper, Kraft paper has relatively high requirements on the storage environment. First, a dry, well-ventilated, and dust-free indoor space should be selected as a storage location. Excessive humidity can cause the paper to absorb moisture, deform, or even become moldy; while poor ventilation can easily cause the paper to become damp or dusty, affecting its quality. Therefore, ensuring that the humidity of the storage environment is controlled at around 50% and regularly opening windows for ventilation is the basis for maintaining the excellent performance of Kraft paper.

 

Stacking and placement of paper
The stacking and placement of paper is an important part of ensuring that it maintains excellent performance for a long time. For Kraft paper, the way it is stacked and placed should follow some basic principles to maximize the quality and integrity of the paper. The stacking of paper should follow the principle of "handle it with care and be neat and orderly". During transportation, violent vibrations and collisions should be avoided to prevent damage to the paper. When stacking, paper should be stacked vertically and avoid stacking horizontally to reduce friction and wear between papers. At the same time, the stacking height should be moderate and should not be too high to avoid excessive pressure on the paper at the bottom. When placing paper, pay attention to the flatness and smoothness of the paper. Papers should be sorted into categories of the same size and type to make them easier to manage and find. For Kraft paper, due to its generally large size and weight, special care should be taken when placing it to avoid bending, wrinkles, or damage to the paper. In order to prevent the paper from getting damp and moldy, the floor where the paper is stacked should be kept dry and clean. Pallets or racks can be used to isolate the paper from the floor to ensure some air circulation between the paper and the floor. At the same time, when stacking papers, enough space should be left for ventilation and inspection. To prevent paper from fading or aging due to exposure to direct sunlight, the paper should be stacked in a location that avoids direct sunlight. You can use shades or curtains to keep the paper in a cool environment. For long-term storage of Kraft paper, it should also be turned and inspected regularly. Turning the paper can reduce the adhesion and indentation between the papers and keep the paper flat and smooth. At the same time, check whether the paper is deformed, moldy or damaged, and deal with it in time if found.

 

Measures to prevent pests and rats
To ensure the safety of Kraft paper, insect and rodent prevention should be done. Install rat-proof nets, insect repellents and other measures in storage areas, and conduct regular inspections and maintenance. At the same time, keep the storage area clean and hygienic to avoid food residues and other attracting pests.

 

Fire safety measures
Kraft paper is flammable, so fire safety measures are crucial. Fire extinguishers and other fire-fighting equipment should be equipped in storage areas and their effectiveness should be checked regularly. At the same time, we strengthen fire safety awareness training for employees to ensure that they can respond quickly and effectively in emergencies.

 

Regular inspection and turnover
To maintain the excellent performance of Kraft paper, stored paper should be checked and turned regularly. Check whether the paper is deformed, moldy, damaged, etc. If found, deal with it in time. At the same time, turning the paper regularly can reduce the adhesion and indentation between the papers and maintain the flatness and smoothness of the paper.

 

Reasonable control of inventory
Reasonable control of Kraft paper inventory is also an important measure to ensure its long-term excellent performance. Excessive inventory will lead to a long backlog of paper, increasing risks such as moisture and deformation; while too little inventory may affect production progress and cost control. Therefore, a reasonable inventory plan should be developed based on actual demand and market demand to ensure a balance between paper supply and demand.

 

Precautions during transportation and use
When handling and using Kraft paper, you should also pay attention to some details. During transportation, violent vibrations and collisions should be avoided to avoid damaging the paper; during use, friction and scratches on the paper should be avoided to keep its surface flat and smooth.

Kraft paper Pulping: Sustainable & Efficient Paper Production
 

 

Fibers
Softwood and hardwood can be used for making kraft paper. Kraft paper can also use non-wood agri-residues and waste paper in the manufacturing process.

 

Chemicals
Pulp cooking chemicals are also called “white liquor.” This mixture has active ingredients, like NaOH and Na2S, that are used for cooking the wood chips in the digester for pulp production. While there isn't a hard and fast rule on the ratio of chemicals, in general, 25 to 35% sulfidity is maintained. Any lower, especially below 15%, affects the reaction rate and pulp quality of the resulting products.

 

Kraft Pulping Process
The kraft process, sometimes called “Kraft Pulping” or the “Sulfate Process,” is the process by which wood is turned into wood pulp, the main component of the paper. Wood chips are treated with a hot mixture of water, sodium hydroxide (NaOH), and sodium sulfide (Na2S) in large pressure vessels called digesters. These large devices can hold 10-20 tons of pulp and come in two processing types: batch and continuous. This chemical mixture breaks down the bonds that link lignin, hemicellulose, and cellulose. One of the major benefits of kraft pulping is that roughly 90% of the pulping chemicals can be recovered and reused in an economical manner. This makes the process more sustainable and affordable at the same time.
