Aluminum Hydroxide is a white powder which can be used as flame retardant and filler.
While it is used for resin Solid Surface,It has characteristic of white crystalline powder, non-toxic, tasteless, good mobility, low oil absorption, low iron content, particle morphology, particle size distribution, low impurity content, good stability, high whiteness, uniform particle size and good dispersibility.
While it is used for composite materials,it has characteristic of micro powder,high white powder without secondary pollution,smoke elimination, filling, antistatic.The initial decomposition temperature of aluminum hydroxide is about 205 �ºC. Aluminum hydroxide flame retardant can release a large amount of water vapor when heated. A large amount of water vapor can store heat and dilute the concentration of polymer combustible gas. It can also form a non combustible barrier between the combustion source and the matrix material to achieve the purpose of flame retardant. At the same time, it is also a smoke suppressant, because the gas it releases is water vapor, which has no corrosion to metals.

Sodium lignosulfonate is used as a defoamer in papermaking in the food industry and as an adhesive in articles that come in contact with food. It has antiseptic properties and is used as an ingredient in animal feed. It is also used in construction, ceramics, mineral powder, chemical industry, textile industry, metallurgical industry, petroleum industry, flame retardant materials, rubber vulcanization, organic polymerization. It is a pepsin inhibitor.
sodium lignosulfonate uses in construction
The applications of lignin and its modified products are mainly in the following aspects:
(1) Cement and concrete water reducer: Lignosulfonate is currently the most widely used water reducer. In 1935, successfully developed a water-reducing agent with lignosulfonate as the main component. Since then, mankind has begun the research on lignosulfonate water-reducing agent. The use of lignosulfonate as a water reducing agent for cement and concrete can not only greatly improve its fluidity and plasticity, but also greatly reduce harmful pores and significantly enhance compressive strength.
(2) Dispersant, flocculant and corrosion and scale inhibitor: Lignosulfonate is an anionic surfactant with excellent performance, which can be used as dispersant, flocculant, etc.
(3) Oilfield chemicals: Lignosulfonates have a special molecular structure and are widely used in oilfield chemicals. They are often used as tertiary oil recovery surfactants, drilling fluid treatment agents, and water shutoff agents.
(4) Synthetic resin: Since the 1990s, lignin has often been used as a basic renewable material for synthetic polymer materials, resins and adhesives.
(5) Polymer materials: Lignin and its derivatives can be blended with polyvinyl chloride (PVC), polyethylene (PE), polyvinyl alcohol (PVA) and other olefin polymer materials to improve the stability, strength and Anti-photolysis and other properties. Liu Chunfang and others added lignosulfonate to rubber as a rubber reinforcing agent, which can improve the mechanical properties of rubber. Li Haijiang and others compounded hydrolyzed lignin with natural rubber to form an interpenetrating network structure, and then prepared a lignin-natural rubber compound by co-precipitation.
(6) Agricultural additives: Sodium lignosulfonate can be used not only as a pesticide dispersant, but also as a wetting agent, complexing agent and fertilizer enhancer, and is widely used in all aspects of agriculture.
