How to make good pulp for egg trays
The production of pulp for egg trays mainly involves converting waste paper or cardboard into pulp suitable for making egg trays. Here are some basic steps that can help you make high-quality egg tray pulp:
stores reserve
Waste paper or cardboard: old newspapers, cardboard boxes, cardboard, etc. can be used.
Water: Used for soaking and mixing paper.
Adhesive (optional): such as wood glue or starch, used to enhance the adhesion and strength of pulp.
step
Tear up paper:
Tear waste paper or cardboard into small pieces for easy soaking and mixing in the future. The smaller the shredded paper, the easier it is to make a uniform mixture of pulp.
Soak paper:
Put the shredded paper into a large container, add enough water, and soak for several hours until the paper is completely soaked. Wet paper is more easily mixed into pulp.
Mixing into pulp:
Use a blender (such as a blender, food processor, or specialized pulp mixer) to mix wet paper into a uniform pulp. The stirring time and speed will affect the fineness of the pulp, usually stirring for 5-10 minutes is sufficient.
Adjust pulp concentration:
Adjust the pulp concentration as needed. If the pulp is too thick, you can add some water; If it is too thin, more shredded paper can be added.
Add adhesive (optional):
If it is necessary to enhance the strength of pulp, a small amount of adhesive such as wood glue or starch can be added. Generally speaking, the proportion of adhesive is 2-5% of pulp. Stir thoroughly and mix evenly.
Screening and Drainage:
Pour the pulp into the sieve and gently press to remove excess moisture. The sieve can be a specialized sieve for pulp or a regular fine mesh sieve can be used.
forming:
Pour the drained pulp into the egg tray mold and compact it to ensure that the pulp evenly fills every corner of the mold. Special molds or self-made molds can be used.
dry:
Place the mold in a well ventilated area and wait for the pulp to dry. The drying time varies depending on environmental conditions and usually takes 24 hours or more.
Demoulding and trimming:
After the pulp is completely dry, remove the egg tray from the mold. If necessary, the edges can be trimmed or surface treated.
Tips
Using environmentally friendly materials: Choosing recycled paper and eco-friendly adhesives can help reduce the impact on the environment.
Control moisture: Maintaining appropriate pulp moisture can prevent the egg tray from being too fragile or too heavy.
Mold cleaning: Before and after using the mold, keep it clean to avoid affecting the quality of the egg tray.
Through the above steps, you can produce high-quality egg tray pulp and adjust and improve it according to actual needs.
