In the process of beating, several kinds of raw materials can be quantitatively added into the slurry tank according to the designed slurry ratio, and the slurry can be sized and a small amount of functional additives can be added. If a sizing agent is added to increase the liquid penetration resistance of the paper molded product, the sizing agent used is generally rosin, paraffin wax latex or rosin paraffin wax glue. It is worth mentioning that the product cannot be called environmentally friendly paper support after adding this additive. For non-bonding waste paper product pulp, add rosin glue equivalent to 3% of the absolute dry fiber mass of the pulp; for bonded waste paper products For pulp, 1.5%-2% rosin glue should be added. Talcum powder can also be added to the pulp as a filler to achieve a higher retention rate of the slurry. An aqueous suspension containing 20%-30% of the talc filler can be treated in a mixer at high speed for 6 minutes, and then diluted with water and added with chemical aids. It is treated for another 5 minutes to make a filler suspension, which is then added to the slurry. Some manufacturers also added a small amount of oil repellent, water repellent, wet strength agent and retention aid to the slurry. Plant fiber cushioning packaging uses crushed crop straws and new knots as raw materials, and is processed through processes such as mixing, reaction, foaming, squeezing, baking and shaping, and natural drying. In the pulping process, an appropriate amount of white water or clean water should be added to adjust the pulp loading concentration to 1%-2% for the production of molded products.
Conditions that need to be paid attention to in the manufacture of pulp molding
What conditions need to be paid attention to in the manufacture of pulp molding? For the current pulp molding, it is more straightforward to consider a very large consideration based on the overall manufacturing requirements of the entire diameter molding.
In terms of the overall production form of such pulp molding, the basic data lies in the size and specifications of the entire pulp molding, which is considered as the main analytical value of the overall construction of such pulp molding.
So for the pulp molding in the entire market now, it is more important to analyze the production and sales situation in the market. From the perspective of the production and construction needs of such pulp molding, from the production of equipment to the entire pulp From the perspective of the overall construction value of molding, this is a very promising overall requirement.
From the perspective of the main analysis of the overall construction of the entire diameter molding, it is important to consider the overall value of the construction to analyze the specific value of the construction. In the production requirements for such diameter molding, it can be seen that different models There are certain requirements for the different specifications that need to be paid attention to in pulp molding.
Do paper products have the function of waterproof and heat insulation?
Paper itself is not waterproof, but environmentally friendly paper plastics are different. Environmentally friendly paper plastics are processed from virgin pulp into paper plastics. Waterproofing agents are added to the pulp (such chemicals are non-toxic and pollution-free. Time is increased or decreased according to the waterproof performance requirements and effects of the product) and constantly stirred, after it is fully melted, so that the waterproof effect can be achieved.
Environmentally friendly paper-plastic thermal insulation can start from enhancing the hardness and thickness of the paper-plastic product itself. The thermal insulation performance of the thickness of a computer will naturally be better. In the pulping process, adjust the pulp concentration appropriately to enhance the bonding strength between the fibers, and avoid cutting the fibers as much as possible to maintain its toughness.
