Aluminium oxide is a chemical compound of aluminium and oxygen with the chemical formula Al2O3. It is the most commonly occurring of several aluminium oxides, and specifically identified as aluminium(III) oxide. It is commonly called alumina, and may also be called aloxide, aloxite, or alundum depending on particular forms or applications. It occurs naturally in its crystalline polymorphic phase α-Al2O3 as the mineral corundum, varieties of which form the precious gemstones ruby and sapphire. Al2O3 is significant in its use to produce aluminium metal, as an abrasive owing to its hardness, and as a refractory material owing to its high melting point.

The effect without enhancement at room temperature is the same. When 15% silicon carbide is added to the epoxy resin, the amount of wear is reduced by 17%. In addition, it is also widely used in ceramics, environmental protection, energy and other fields. Used as a reinforcing fiber and radio wave absorbing material for composite materials such as resins, metals, and ceramics. It is also used as a material for space and space energy. Raw materials for high-density sintered body, high-temperature resistant structural materials, corrosion-resistant and wear-resistant materials. Toxicity and protection allowable concentration 10mg/m3.

Important vinyl monomer. The homopolymer produced by polymerization is insoluble in water, but has ~~"water respiration~~". The water absorption rate can reach 20-25% of the resin~"s own weight, and when the ambient humidity is lower than 60%, the moisture absorbed by the polymer is released again. The moisture acts as a plasticizer for the polymer. Using this peculiar nature, a variety of applications can be developed. (1) Resins for perm with good moisture resistance Japan uses it for resins for perm with moisture resistance. The hairstyle is kept for a long time, and it is not deformed by rain and rinse. (2) Photosensitive resin This product is used as a part of the raw material of photosensitive resin, which can have the following characteristics: fast photosensitive speed; easy removal of non-image parts after exposure can obtain clear images; can obtain good strength, solvent resistance and water resistance Layout. In addition, it can also be used as a cross-linking agent for unsaturated polyester resins, a cross-linking agent for diallyl phthalate, a curing agent for epoxy resins, such as for ~~"water breathing~~" resin (contact glasses, prevent Glass fogging, ship bottom coatings, etc.), pressure-sensitive adhesives, adhesive modifiers, non-woven fabric adhesives, water-absorbing films, leather finishes and modifiers, paper strength enhancers, antistatic polymers, inks, etc. This product can be used in the production of water treatment agents, such as scale inhibitors, flocculants; temperature and salt resistance drilling fluid loss control agents, oil well cement fluid loss control agents and temperature and salt resistance polymer oil displacement agents. It can also be used in the modification of fiber materials, daily chemicals, printing, papermaking, electronics and photography, medicine and health.

Adipic acid dihydrazide (ADH) is a chemical used for cross-linking water-based emulsions. It can also be used as a hardener for certain epoxy resins. ADH is a symmetrical molecule with a C4 backbone and the reactive group is C=ONHNH2. Dihydrazides are made by the reaction of an organic acid with hydrazine. Other dihydrazides with different backbones are also common, including isophthalic dihydrazide (IDH) and sebacic dihydrazide (SDH).
