- Q:What are the criteria for the classification of plastic materials at injection molding and extrusion?
- In comparison, the lower melt flow rate is applicable to the extrusion grade, and the higher is applicable to the injection molding grade. As to what is low and what is high, there is a difference between the different plastic varieties.
- Q:What is the difference between plastic particles and raw materials?
- Special plastics: thermosetting plastics, functional polymers, plastics, such as artificial kidney. Heart. Blood vessel。 Aerospace industry, etc.
- 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 plastic material is used for plastic hose?
- PP: good corrosion resistance, high strength, high surface hardness, good surface finish, have certain resistance to high temperature hot melt welding, flange connecting thread, sea water, oil and chemical sewage irrigation pipe, concrete floor for indoor heating system for heating pipe
- Q:What are the specific differences between plastics and plastics?
- General characteristics of plastic raw materials (LC plastic raw materials wholesale, high temperature resistant plastic materials, PPS, LCP, PET, PA, PES plastic raw material suppliers):1) the plastic material is heated and compressed, and the coefficient of linear expansion is much larger than that of metal;2) the stiffness of a general plastic material is one order lower than that of the metal;3) the mechanical properties of plastic raw materials will decrease obviously when heated for a long time;4) the general plastic material is temporarily subjected to stress at normal temperature and below its yield strength, and permanent deformation occurs;5) plastic raw materials wholesale, sensitive to notch damage;6) the mechanical properties of plastic raw materials are usually much lower than those of metals, but some composite materials have higher specific strength and specific modulus than metals. If the products are properly designed, they will be more effective;7) the mechanical properties of reinforced plastic raw materials are various;8) some plastic materials absorb moisture and cause changes in size and properties;9) some plastics are flammable.
- Q:What is the concept of plastic raw materials for turnover containers?
- Plastic turnover box, other features: 1) plastic turnover box outer dimension refers to the maximum size of the logistics box cover. 2) the plastic turnover box has no standard inner concave, and the case size is 18mm. 3) the carrying capacity of a plastic turnover box means that the load is uniformly placed within the range of the environmental temperature. 4) the effective working temperature of the plastic turnover box is -25 DEG C - 40 DEG C. 5) plastic turnover boxes can be stacked for storage, saving space.
- Q:What's the difference between recycled plastic bucket and plastic bucket made of raw material?
- The biggest difference is strength. Do good strength, good performance. Recycled materials are generally impure and contain many fillings which are brittle and easily damaged.
- Q:Plastic PPT30S add what material will increase hardness?
- Technical parameters of Qilu Petrochemical PP (T30S)Project quality index test method of isotactic index% greater than 95 GB/T 2412 powder ash%, less than 0.03 GB/T 9345 tensile yield strength greater than 28 GB/T, MPa 1040 kg/m3 0.9~0.91 density, cleanness, color particle, /kg melt flow rate of 11~20, g/10min 2~4 GB/T 3682 brand name: Qilu
- Q:What's the shell of the relay? What exactly is plastic?
- Relays, usually thermosetting plastics, refer to plastics that can be cured or otherwise insoluble in heat or other conditions, such as phenolics, epoxy plastics, etc.. Thermosetting plastics can be divided into two types: formaldehyde, cross-linking and other cross-linking. Formaldehyde crosslinked plastics include phenolic plastics and amino plastics (such as urea formaldehyde melamine formaldehyde etc.). Other crosslinked plastics include unsaturated polyester, epoxy resin, phthalic two, diallyl resin, etc..
- Q:What is the raw material for producing corn starch plastic film?
- At present, China's maize production in 1.31.5 million tons, only 1/10 of the corn crop is processed into starch, used in the textile industry, paper industry, food industry, medical industry and other fields, the total amount of nearly 10 million tons of starch (including corn starch close to 9 million tons; 420 thousand tons of cassava starch, potato starch, 240 thousand tons).
