Nowadays, most of the incense-making processes use polyacrylamide as a thickener and binder, and polyacrylamide for incense-making is also called special incense powder and incense-making binder.
In the process of fragrance making, most of the anionic polyacrylamide used is 12 million to 20 million molecular weight. The higher the molecular weight of anionic polyacrylamide, the greater its viscosity coefficient, the more obvious the thickening effect, and the less the dosage.
The solid polyacrylamide is dissolved in water according to the corresponding proportion, and the fragrance-making raw materials are added after complete dissolution, and the mixture can be fully mixed by stirring (the addition ratio is determined by the molecular weight of the anionic flocculant, and the molecular weight of the anionic flocculant 20 million is usually 1/1000 to 5/1000. The amount of polyacrylamide is gradually increased in sequence with low molecular weight).
The reason why it can be used as a thickener in fragrance making is mainly related to its viscosity. Because when anionic polyacrylamide dissolves, it will expand from solid particles and form micelles, which have a great viscosity. The viscosity of anionic polyacrylamide can be used to bond fragrance products tightly together, thereby improving the quality of fragrance products. At the same time, after adding thickener anionic polyacrylamide, the quality of fragrance products can be effectively improved in all aspects.
1. Polyacrylamide has a high viscosity after being dissolved in water. Adding anionic polyacrylamide during the production process of fragrance can cause the rubber powder particles near the burning point of the incense head to quickly lose water and dry to form a fine microporous structure. The micropores are filled with air to improve flammability.
2. The finished product is fragrant, the surface is smooth, the mold is not sticky, the blank body has no cracking phenomenon, and the shape of the formed product is beautiful and delicate.
3. At the same time, it significantly enhances the flexural strength of the incense. The high-viscosity anionic polyacrylamide has the stretchability to ensure that the incense will not break during transportation and is not easy to break.

5. The use of this product can greatly save the overall production cost of incense. After the polyacrylamide was put into use in the incense market, a large number of practices have confirmed that it can be used alone instead of mixed binders such as sticky wood powder, elm skin powder, root powder, and adhesive, and the amount of this incense-making binder is half that of ordinary incense-making binders. This not only saves the amount of raw materials, procurement, quality inspection and other procedures, but also reduces process links and equipment, maximizing manpower and material resources.
Fragrance products with thickener anionic polyacrylamide added have the advantages of high finish, not easy to fade, strong flexibility, not easy to fold, good flammability, non-toxic and harmless, and odorless when burned.
How to use and precautions:
1. Through a small test, determine the best model and the optimum dosage of the product.
2. The product is formulated into an aqueous solution with a concentration of 0.1% to 0.3% (referring to the solid content), preferably neutral water without salt.
3. When preparing PAM aqueous solution, it should be carried out in enamel, galvanized, aluminum or plastic drums, and should not be prepared and stored in iron containers.
4. This product is hygroscopic and should be sealed and stored in a cool and dry place at a temperature lower than 35 ° C.
5. Avoid sprinkling solid products on the ground to prevent the ground from becoming slippery after the product absorbs moisture.
6. Formulate at a suitable temperature. When dissolving, pay attention to adding the product evenly and slowly to the dissolver with stirring and heating measures (proper heating (< 60 ° C) can accelerate dissolution), and avoid solidification. And should avoid long-term excessive mechanical shearing. It is recommended that the stirrer be 60-200 rpm, otherwise it will cause polymer degradation.
7. The PAM aqueous solution should be ready-to-use. When the dissolved liquid is left for a long time, its performance will gradually decrease depending on the water quality.
