Usage
Used in the paper industry, one is to increase the retention rate of fillers and pigments. In order to reduce the loss of raw materials and pollution to the environment; the second is to increase the strength of the paper (including dry strength and wet strength). In addition, PAM can also increase the tear resistance and porosity of the paper when used, so as to improve the vision and printing performance. Used in food and tea packaging paper. It is widely used in petroleum industry, oil recovery, drilling mud, waste mud treatment, preventing water channeling, reducing friction, improving oil recovery, and tertiary oil recovery. Used as a textile sizing agent, with stable sizing performance, less sizing, low rate of fabric breakage, and smooth fabric surface. PAM is also widely used in thickening, stabilizing colloids, drag reduction, bonding, film formation, biomedical materials, etc. Used in daily chemical industry, it is often combined with laureth-7 and C13-14 isoparaffin in sleep mask to form an emulsion-like thickening, emulsifying and stabilizing agent. Other industries, food industry, used for cane juice clarification and syrup phosphorous float extraction in the production of cane sugar and beet sugar. Enzyme preparation fermentation broth flocculation and clarification industry, also used for the recovery of feed protein, stable quality, good performance, recovered protein powder has no adverse effects on the survival rate of chickens, weight gain, and egg production. Synthetic resin coatings and civil construction grouting materials are blocked. Water, building materials industry, cement quality improvement, construction industry adhesives, joint repair and water plugging agents, soil improvement, electroplating industry, printing and dyeing industry, etc.

Storage and transportation
Protect from rain and hot sun during transportation. Be careful when loading and unloading to prevent damage to the package. In case of fire, water, sand, carbon dioxide fire extinguishers can be used to fight the fire. The packaging should be intact at the time of shipment, and the loading should be secure. During transportation, ensure that the container does not leak, collapse, fall, or be damaged. It is strictly forbidden to mix and transport with combustibles, combustibles, acids, edible chemicals, etc. It is not suitable for transportation on rainy days. Store in a cool, ventilated warehouse. The storage temperature should not exceed 30℃, and the humidity in the storage should be no more than 85%. The packaging must be properly sealed to avoid moisture absorption. It should be stored separately from oxidants, acids, alkalis, flammable (flammable) materials, etc., and should not be stored together. The storage area should be equipped with appropriate information to contain the leakage. Transport vehicles should be equipped with leakage emergency treatment equipment during transportation.

Safety Precautions
Airtight operation, strengthen ventilation. Operators must undergo special training and strictly abide by the operating procedures. It is recommended that operators wear self-priming filter dust masks, chemical safety goggles, anti-poison penetration overalls, and rubber gloves. Avoid generating dust. When handling, please load and unload with care to prevent damage to packaging and containers. Equipped with leakage emergency treatment equipment. The operator wears labor protection equipment during use or transportation.
