Q:What plastic material is used for plastic hose?
PE: the main raw material for polyethylene. The performance of light weight, good toughness, good low temperature resistance, non-toxic, low cost, high impact strength, compressive strength and tensile strength but lower thermal welding, flange connecting thread water pipe, rain water pipe, gas pipe, industrial pipe corrosion.
Q:What are the materials for making plastic basins? Are they raw materials?
PP material ah! Usually with raw materials, slightly more mouth material!
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: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:I'd like to know what PP plastic material is PP plastic raw materials cleaning can not use ultrasonic cleaning machine to wash it?
After research, "ultrasonic cleaning machine" function is that as long as the liquid can be immersed in the sound field, the product exists in the cleaning role, and the cleaning speed, high quality. Especially for PP plastic raw materials, under the action of ultrasound, it takes only 5-10 minutes to complete. The speed is several times as many as that of the traditional method, and the cleanliness is also high.
Q:What are the raw materials needed for making plastic bags?
The bags made of two materials each have their own characteristics, and are chosen according to the purpose and performance of the products. Polyethylene is petrochemical products, prices vary according to crude oil and market conditions every day, at present LDPE (high pressure polyethylene) offer at 13500 yuan. HDPE (low pressure polyethylene) at 11000 yuan up and down.
Q:I made of plastic raw materials accessories containing benzene, how to remove the teacher, please enlighten!
The use of benzene: fats, resins and iodine and other solvents. Determination of mineral refractive index. Organic synthesis. Optically pure solvent. High pressure liquid chromatography is used as solvent, synthetic dyes, pharmaceuticals, pesticides, petroleum and chemical products, photographic materials, varnishes, nitrocellulose lacquer thinners, paint remover, lubricating oil, grease, wax, Sai Luluo, resin, artificial leather and other solvents. It must be the raw material you bought that contains some other additives. Benzene is not removed
Q:Pollution in the production of plastic raw materials from petroleum production
Petroleum - intermediate - polymerization monomer - resin - plastic particles - plastic products, the process of the above, each will have pollutants!
Q:What two ingredients fit together to solidify like plastic?
What is the material of plastics? This is important because even the adhesive with high bond strength can not be well adhered to on some surfaces, such as PTFE.
Q:Chemical, plastic raw materials, plastic raw materials how sub grade?
That's because the raw material used for making plastic barrels is different. Just like the quality of the clothes, the grades of the fabrics used are different, and the products presented are definitely different.
