Q:What are the main raw materials used in plastic products?
PS plastic (polystyrene) English Name: PolystyreneSpecific gravity: 1.05 g / cubic centimeter molding shrinkage: 0.6-0.8% molding temperature: 170-250 DEG C drying conditions: ---The 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 and strength. In general, but the crisp, easy to produce stress cracking, no resistance to benzene. Gasoline and other organic solvents. Suitable for making insulating transparent ornament and. Chemical equipment. Optical instruments and other parts.Molding performance 1. amorphous material, moisture absorption is small, not to be fully dry, not easy to break down, but the coefficient of thermal expansion is large, easy to produce internal stress. Better liquidity, can be used screw or plunger injection molding machine2., should use high material temperature, high mold temperature, low injection pressure, extended injection time, is conducive to reducing internal stress, prevent shrinkage, deformation3., can be used in various forms of gate, gate and plastic parts arc connection, so as not to go to the gate when damaged plastic parts. Stripping large slope, top out even. Plastic parts wall thickness uniform, preferably without insert, if inserts should be preheated
Q:Waste plastics recycling plant how to solve environmental problems
Waste plastics recycling plant; environmental protection:1, the environmental impact assessment must be carried out in accordance with the environmental laws and regulations of the state. Then get approval from the local environmental protection department.2, the construction of sewage treatment facilities to meet production requirements.
Q:What are the benefits of plastic bags? What's the disadvantage?
Advantages of plastic bags: the invention of plastic bags brings convenience and sanitary life for human beings. The emergence of plastic bags will also reduce food waste, the nature of the fungusproof mold also protected the health of human beings, plastic bags are used instead of other packaging materials such as paper, glass, cans, etc., to reduce energy loss;
Q:Plastic molding is what to do, how the process?
The choice of plastic molding is mainly determined by the type of plastic (thermoplastic or thermosetting), the starting form, and the shape and size of the product. The commonly used methods for processing thermoplastics are extrusion, injection molding, calendering, blow molding and thermoforming. Thermosetting plastics are generally molded, delivered and molded by injection molding. The plastic molding is various forms (such as powder, granules, solution and dispersion) of plastic products or parts required for the shape of. As many as 30 kinds of molding method. Lamination, molding and thermoforming are the processes of forming plastics on a flat surface. The plastic processing method can be used for rubber processing. In addition, there are liquid monomers or polymers as raw materials such as casting. In these methods, extrusion and injection molding are the most widely used and the most basic molding methods.
Q:Standard for classification of fire protection in plastic products
2, V-2: the sample was subjected to two 10 second combustion tests, and the flame died within 60 seconds. A fire can fall off. 3, V-1: the sample was subjected to two 10 second combustion tests, and the flame died within 60 seconds. No fire can fall. 4, V-0: the sample was subjected to two 10 second combustion tests, and the flame died within 30 seconds. No fire can fall.
Q:How to mend cracks in a plastic bucket?
Bad mouth at the pelvic floor or waist, it is best to change the new. Because the adhesive parts are not resistant to water pressure, and where there is adhesive, there is a crumb of rubber, etc. things will stick on it.
Q:Why don't you put the plastic bags in the fridge?
Don't put the plastic bags in the refrigerator, or the consequences will be serious.
Q:New plastic products have a strong taste, how to remove?
Method: the use of ventilation air flow away dilution plastic taste, can also use the electric fan to blow, or outdoor fresh air to the mountains "bubble". Need to remind is, some people use negative oxygen ion generator to control low concentration air pollution, but governance effect is not satisfactory, negative oxygen ion is easy to change into ozone, cause two pollution.
Q:What are the advantages and disadvantages of plastic packaging materials?
Secondly, the plastic material has a very suitable barrier and permeability, you know, in plastic packaging, there is gas barrier packaging. Moisture proof packaging, waterproof packaging, and all kinds of fresh fruit packaging. These are plastic packaging to meet the respiratory effects of fresh ingredients. Again, the optical properties of plastic packaging is very good, because the plastic packaging materials can be made transparent, so when it is made of packaging containers, for which we see the contents of the indirect effect of crystal clear, very good promotion way.
Q:What are the characteristics of plastic products?
Three indispensable synthetic materials in daily life. Specifically, the plastic is made of natural or synthetic resin as the main ingredient, adding various additives, in certain conditions such as temperature and pressure can be made into a certain shape, keep shape materials at room temperature.
