1、 Raw material production of plastic products of plastic hanger:
1. Nowadays, the common synthetic resins of general plastics are high-pressure polyethylene (PE), polypropylene (PP), polyethylene (PS), polyethylene (PVC), modified materials polyethylene (ABS) polycarbonate (PC), etc.
2. Fillers can improve the strength heat resistance of plastics reduce the cost. Commonly used are wood powder, plant fiber, glass fiber, diatomite, asbestos, carbon black, etc. Plasticizers can increase the plasticity flexibility of plastics. Phthalates are commonly used.
3. Stabilizers are often used, such as stearates epoxies, to prevent the synthetic resin being light heat decomposed destroyed.
4. Colorants give plastics a variety of colors. Organic dyes inorganic pigments are usually used.
5. The lubricant makes the plastic stick to the mold, making the plastic surface smooth beautiful. Glycerol stearate is commonly used.
2、 How to distinguish the plastic products of the plastic hanger:
1. Touch: touch the edge of the goods, there is no feeling of stabbing the hand, the edge is clean, most of the molds are better, flash repair is better; the feeling is very sharp, the edge is also very rough, mainly because the molds are poor.
2. Smell: the fragrance is indifferent, but the products with good quality light plastic taste have more smell of plastic, the products with poor quality strong plastic taste have more pungent taste.
3. Vision: transparent colorless products have good transparency, products without impurities have good quality (mostly produced by raw granular materials), such as fresh-keeping bags, cups, lunch boxes, fresh-keeping boxes other products. Products with low transparency a large amount of impurities (mainly produced by raw material powder), such as finishing boxes, basins, hangers stools. Opaque goods are mostly business
Products with poor quality (mostly produced by return materials, but return materials can be divided into many kinds, such as the return materials produced by the manufacturer's trimming; the products returned to the manufacturer by the dealer) such as garbage cans, bin liners garbage bags.
3、 How to choose the plastic products of the plastic hanger
1. Commercial plastic packaging household plastic packaging is mainly polyethylene (PE) plastic film. When purchasing, you should see the signs of "polyethylene", "PVC free", "microwave heating", use fire to disperse white smoke. This product is safe.
2. Plastic bags should be purchased in large shopping malls reputable supermarkets. There are also some simple methods to identify the plastic bag with good safety: the hand has a smooth feeling, shaking has a clear sound, it is inflammable emits white smoke in case of fire, it comes out of the water when entering the water, without smell color.
3. Another kind of fresh-keeping film is PVC plastic film, which is characterized by good transparency, easy to crack, strong adhesion, low price, obvious burnt black trace when burning. In the process of processing, a large amount of plasticizer phthalate is added to the film, which will release harmful components when exposed to heat oil, it is only suitable for the cold storage of vegetables fruits.
