- Q: What plastic material has great impact resistance?
- Plastic raw materials Linai the maximum impact strength is MC nylon, the impact strength was > 500 kg. L cm / cm, nylon 11 cm / cm - 380 kg. The impact strength of polycarbonate, poly (phenol oxide), F-46, poly phenol, Yaan, low pressure polyethylene, polypropylene and nylon 1010 unreinforced is continuous".
- Q: Low pressure plastic raw materials in the process of blowing the two sides of the fold, how to deal with?
- However, blow ratio can not be too large, otherwise easy to cause the bubble unstable and prone to wrinkle film. Therefore, the blow up ratio should be equal to the traction ratio. Generally speaking, the blow up ratio of low-density polyethylene (LDPE) film should be controlled at 2.5-3.0.
- Q: What are the raw materials of foam plastics and how do they come out?
- More bisphenol A epoxy resin, epoxy value of 0.51 ~ 0.22mol/100g. When the viscosity is 25 degrees centigrade, it is 20Pa / S; the viscosity is 130 s at 1Pa.
- Q: Is plastic bucket and plastic bottle the same raw material?
- When the number of the triangle in the bottom of the plastic barrel is "3", the main component of the plastic barrel is polyvinyl chloride, also called PVC. This kind of plastic barrels can heat 81 DEG C, and the production process will use a lot of plasticizer (such as plasticizer, DOP) and heavy metal containing heat stabilizer, and the synthesis process is difficult to eliminate the presence of free monomer, these are considered to be toxic. Therefore, this kind of plastic bucket can not be placed people can eat directly, but also can not be recycled. Since the PVC used in this kind of plastic barrel is a kind of plastic which is not high temperature resistant, it can not be used in places where the temperature is higher.
- Q: How many types of plastics are there?
- Name: ABS engineering plastics, can be used for connecting piece, seat back, seat board, it is able to perform plastic electroplating (water plating) the main raw material.
- Q: What can recycled plastics do?
- The source of waste plastic materials, where there was a waste plastic, easy to buy, cheap (around, so) a city daily consumption of plastic bags and other plastic products reached more than 10 tons in rural areas have a lot of plastic waste plastic particles Recyclable, don't worry about sales. Suitable for partnership enterprises, laid-off workers and individual production. Gong Zhen Xiao Mao CI is the history of Chin Shan recycled plastic base professional manufacturer and supplier. Hedong District, Shandong City, Linyi province has built the largest national renewable plastic base in china.
- Q: What are the plastic bags made of?
- Barrels are usually produced in HDPE, and as for plastic bags, these materials can be made, including polypropylene. Relatively soft is made of high pressure material, relatively hard bag is made of low pressure material, hard and quite, is PP do. Linear low density polyethylene has a strong tear resistance and is generally improved by adding a certain percentage to high pressure polyethylene. The requirements are not too high to add some recycled materials and should be appropriate to reduce the cost of filling masterbatch.
- Q: What is the plastic bag made of?
- The main raw material of plastics is oil and natural gas, that is, carbon hydrogen compounds. First, the appropriate macromolecular components in petroleum and natural gas are extracted, first split into monomers, and then polymerized into polymers to become plastic
- Q: What raw materials do plastic color printing plants use?
- PEBOPPOPS film, aluminum film and so on, the ink is usually water-based ink, polypropylene ink, etc., different films with different ink.
- Q: What are the properties of plastic material PS? What are the advantages and disadvantages?
- The parameters of PS plastic (polystyrene) English Name: Polystyrene weight: 1.05 g / cm3 molding shrinkage rate: temperature: 170-250 degrees 0.6-0.8% molding material properties of electrical insulation (especially high-frequency insulation) excellent, colorless and transparent, light transmittance after organic glass, color of water resistance, good chemical stability, strength, but brittle that is easy to produce stress cracking, no resistance to benzene. Gasoline and other organic solvents. Suitable for production of transparent insulation. Trim and chemical equipment. Optical instrument parts forming performance.
