Aluminum alloy is the most commonly used cookware material in the world because of its light weight, fast thermal conductivity, and easy processing and shaping. Most non-stick pans of all types also use aluminum alloy as the base material. Aluminum discs are used to make kitchen utensils, and the use of new materials has become very mature. 1050, 1060, 1100, 3003 aluminum rounds, etc., have good electrical conductivity, thermal conductivity and heat resistance, and are widely used in the production of aluminum pots and pans around the world. Advantages of aluminum discs for non-stick pans: 1. Excellent elongation and tensile strength; 2. Good processing performance, high stamping and stretch forming performance; 3. Gas welding, hydrogen welding, resistance welding, and brazing; 4. High plasticity, electrical conductivity and thermal conductivity; 5. Easy to carry out various pressure processing, extension and bending processing; 6. Excellent corrosion resistance and strong anti-rust properties. The 3003 aluminum discs produced by Hongchang Aluminum are aluminum alloy materials that meet the performance requirements of non-stick pans. The 3003 aluminum discs are a typical Al-Mn alloy. This material has good formability, very good corrosion resistance and Weldability. The non-stick coating in the non-stick pan produced with it should be smooth, the color, covering power and gloss should be basically uniform, without bubbles and falling off, and the coating is completely hot-melted, without obvious defects such as dirt, cracks and explosions.
Oxidized polyethylene waxis made from polyethylene wax after special oxidation process. The molecular chain has certain functional groups, so its miscibility with polar resin has been significantly improved. Due to a certain amount of carbonyl and hydroxyl groups in the molecular chain of oxidized polyethylene wax, the compatibility with fillers, pigments and polar resins is significantly improved. The wettability and dispersibility in polar system are better than that of polyethylene wax, and it also has coupling property. Due to its high melting point and low viscosity, it promotes good resin fluidity, relatively reduces the power consumption of resin mixing, reduces the adhesion between resin and mold, is easy to remove film, plays the role of internal and external lubrication, and has good antistatic property. In the plastic processing industry, the internal and external lubrication of PVC is relatively balanced. The lubricity of oxidized polyethylene wax added to the rigid, transparent and opaque PVC formula is better than that of other lubricants. It can also be used as raw and auxiliary materials for textile softener, car wax and leather softener. It can be used as dispersant, lubricant, brightener and coupling agent of pigment or filler such as dense masterbatch, polypropylene masterbatch, additive masterbatch and filling masterbatch. Rubber and plastic processing lubricants, film removers and phase solvents. In the formulation of waterborne coatings and inks, it provides excellent wear resistance, adhesion resistance and scratch resistance At present, oxidized polyethylene wax is widely used in PVC foam board, but it is less used in other aspects due to price reasons. PVC foam board is the most difficult to produce in PVC products, which has the most problems and is the most difficult to solve. The plasticization can be significantly accelerated after adding oxidized polyethylene wax. Here we can see the uniqueness of oxidized polyethylene wax.
