- Q:What are the materials for making plastic buckets? How many are there?
- Any theory can be made of plastic barrel type container, but for performance and cost considerations, the vast majority of plastic barrels are polyethylene or polypropylene products, drinking machine bucket is the use of polycarbonate (PC). The specific use of what material, to see what you plan to install.
- Q:Is plastic bucket and plastic bottle the same raw material?
- When the number of the triangle in the bottom of the plastic bucket is 2, the main component of this kind of plastic barrel is high-density polyethylene, or HDPE. This kind of plastic barrel has a higher melting point than PET plastic barrel, but the heat resistance can not reach 100 centigrade. HDPE itself is non-toxic. But this kind of plastic barrels in the production process used in some processed or modified additives, such as fillers, stable additives or pigments, these materials contain harmful substances, so this kind of plastic barrels after use not when the containers or other articles.
- Q:Do you have plastic materials that are low in price instead of ABS?
- The PP temperature is 80-100 degrees, and H series of PP high temperature up to 140 degrees, is as the acme of perfection. At present, the only international.
- Q:What are the concepts, classifications and distinctions of modified plastics and plastic materials?
- Modified plastics should, in principle, be made from the plastic raw materials produced by petrochemical plants. By adding plastic additives, they can enhance their hardness, fire resistance, high temperature or low temperature, weather resistance and ultraviolet resistance. Therefore, modified plastics are processed from plastic raw materials, which is the relationship between source and flow.
- Q:How many types of plastics are there?
- PU Name: polyurethane (foam). Mainly used for handrail accessories.Name: POM steel is mainly used for wear parts such as mats, casters, door hinge, hinge and so on. The performance of wear resistance, pressure resistance, but poor dimensional stability.Name: PA nylon. Mainly used as foot, claw, wheel wear, the life of high demand place. Features: wear resistance, pressure resistance, high strength and long service life of indoor, individual models such as PA66 heat up to 2200, is easy to change, easy to break the drying performance, poor weather resistance in the sun.PMMA: organic glass (commonly known as acrylic). There are five kinds of transparent plastic material, and PMMA is one of the highest transparency, cutting when vinegar sour, easy deformation, can turn plastic soaked in boiling water. Disadvantages: easy to scratch the surface, low hardness, easy to crack when bending, the price is higher than ABS more than 20%.
- Q:What raw material (HDPE) made of plastic bags, high transparency, good sense of light master?
- The plastic we usually use is not a pure substance. It is made up of many materials. The polymer (or resin) is the main component of plastic, in addition, in order to improve the performance of plastics, but also add various auxiliary materials in the polymer, such as filler, plasticizer, stabilizer, lubricant, coloring agent, can become the good performance of plastic.
- Q:Plastic pipe gas temperature 150 degrees, plastic pipe surface problems?
- Plastic pipe is usually plastic resin as raw material, adding stabilizers, lubricants, etc., to "plastic" method in the pipe mill by extrusion processing. Because of its light weight, corrosion resistance, beautiful appearance, no bad smell, easy processing, convenient construction and other characteristics, it has been more and more widely used in building engineering. Mainly used for building construction of the water supply system, piping, drainage, exhaust and sewage sanitary pipe, underground drainage pipe system, storm pipe and wire installation supporting the use of threading tubes, and so on.
- Q:What do you mean by grade 1, class two or class three in plastic?
- Two material is that the raw material has been used once, but high pressure granulation except high-pressure granulation using imported large majority, if import large industrial film has not been exposed to the weather, so the quality is very good, the processed particles with good transparency, then it should be judged according to the brightness and surface whether the rough particles.
- Q:What machines and materials are needed for the manufacture of disposable plastic cups?
- The material required is PP, which is polypropylene.The machines needed are injection molding machines, shredders and dryers.PP plastic, chemical name: polypropylene, specific gravity: 0.9-0.91 g / cubic centimeter molding shrinkage: 1.0-2.5% molding temperature: 160-220 DEG C.
- Q:Main ingredients and formulations of PPR tubes
- The main ingredient of PPR tube is polypropylene. The formula is simple. It is added color masterbatch. Suggest not to add any calcium powder and so on.
