A company affiliated with China Aluminum Group produces ultra-fine aluminum hydroxide (Alumina powder) by chemical synthesis. It has extremely high whiteness, low iron, low sodium, low silicon, narrow particle size distribution of the original crystal, good dispersibility, and low oil absorption.
The main production process of ultrafine aluminum hydroxide consists of decomposition, filtration, and drying. Ultrafine aluminum hydroxide is mainly used in halogen-free flame retardant products, which greatly improves the tensile strength, elongation at break, smoke suppression, and flame retardant effect of the flame retardant system. Flame retardant fillers for cables, resins, synthetic rubber, PVC, etc., electronic ceramics, the pharmaceutical industry, and ultra-fine aluminum hydroxide can improve the flame retardancy, arc resistance, trace resistance, etc. of products. Can also be used for catalysts and catalyst supports. and foam materials.
The customer has many tower press filters, Using ultra-fine aluminum hydroxide filtration, the solid is the finished product of ultra-fine aluminum hydroxide; the slurry is processed to the next process, Bolian polypropylene multifilament filter cloth is suitable for the customer's site temperature of about 60 degrees, acid and alkali resistance, the average working life is 50 days.
The filter cloth is elongated, the filter cloth has burrs, the filtrate is turbid, and it is not easy to form a filter cake. Bolian has been sending technical people to the customer side many times, doing On-site research, and communicating with workers to come up with tailor-made solutions.
