- Q: What is the hardness of PAEK+30%GF plastic material?
- Mohs hardness is mainly used in mineral classification. The Mohs scale from I to 10. the scratch resistance increasing (such as talc Mohs hardness is I, the diamond is 10), namely each scale corresponding to the Mohs material can be scraped traces in the previous stage of material. According to the Mohs hardness can determine the scratch resistance between contact with objects in the use of Engineering plastics.Engineering plastics Mohs hardness is between 2 and 3.
- Q: Plastic raw materials, why LDPE and LLDPE?
- LDPE is low density polyethylene, that is, high pressure material; LLDPE is linear material.
- Q: What are the raw materials for plastic products? Resin or oil?
- There is no definite classification of plastics at present. The general classification is as follows: 1.. According to the physical and chemical properties of plastics, thermoplastics can be repeatedly heated, softened and cooled to harden in a certain temperature range. Such as polyethylene plastic, PVC plastic.Thermosetting plastics: Plastics cured by heat or other conditions without melting into insoluble material. Such as phenolic plastics, epoxy plastics and so on
- Q: Plastic raw materials packaging is generally divided into several categories?
- A variety of kraft paper, polyethylene thick film, fiber bags, aluminum foil bags
- Q: What machines and materials are needed for the manufacture of disposable plastic cups?
- PP is crystalline polymer. PP is the most common plastic, and the density is only 0.91g/cm3 (smaller than water). In general plastics, PP has the best heat resistance, and its thermal deformation temperature is 80-100 DEG C and can be boiled in boiling water. PP has good stress cracking resistance and has a high bending fatigue life, commonly known as "fold gum"". PP products are light, tough and chemical resistant.Injection molding machine, also known as injection molding machine or injection machine. It is a thermoplastic or thermosetting plastic plastic molding mold made of plastic products of all shapes of the main molding equipment. The injection molding machine heats the plastic, applying high pressure to the molten plastic to make it crack and fill the mold cavity.
- Q: What kinds of plastic properties can be divided into thermal properties?
- A. thermoplastic(a) polyvinyl chloride (PVC)Is the most widely used plastic varieties. Polyvinyl chloride resin is made from poly (vinyl chloride) monomer. According to the amount of plasticizer, it is divided into hard PVC and soft PVC. The former adds 30~70 phr of plasticizer <5 in 100 heavy resins, and the latter adds plasticizers.Physical properties: the relative density of hard PVC is 1.35 to 1.60, which is 1 / 5 of carbon steel; the relative density of soft PVC is 1.2 ~ 1.4.The water absorption rate of hard PVC is very low. The water absorption rate in long-term immersion in water is <0.5%; the soaking water is 24h, and the water absorption is 0.05%. The permeability of PVC is very low.The glass state temperature of PVC is 80~85 DEG C, the viscosity is 180 DEG C, the decomposition temperature is 240~260 DEG C (including stabilizer), and the brittleness temperature is -50 ~ -60 DEG C.The recommended temperature range of hard PVC is, in principle, maintained in terms of brittleness and glass temperature. If it is used above 50 degrees, necessary measures should be taken.The pure PVC, without stabilizers, begins to decompose at 150 C, releases hydrogen chloride, and further accelerates its decomposition. It decomposes faster than 180 DEG C. The polyvinyl chloride with the stabilizer decomposes the temperature to 240~260 degrees centigrade, but breaks down hydrogen chloride if used for 220 years. The material changes from dark grey to yellow brown, or even black. Therefore, in welding, we should try to avoid this phenomenon, the linear expansion coefficient of hard polyvinyl chloride is (5~6) X10-5 / DEG, 5-6 times larger than carbon steel. Therefore, when installing polyvinyl chloride pipes, expansion joints or bracing shall be installed to prevent deformation. When polyvinyl chloride is used as lining or bonding with other materials, the peeling phenomenon may be considered when heated.
- Q: Plastic raw materials are granular, why not powder?
- Who says plastic raw materials are granular?.
- Q: Characteristics and uses of CA plastics
- Because of its characteristics and quality of different varieties are different, generally use as general plastics, in addition to avoid the use of related in food packaging, medical devices and health fields, the other is used. For example, car interior and exterior shell, household appliances and other daily necessities, mainly low price.
- Q: Does anyone know what kind of plastic material PP-M40 is?
- High gloss PP has high gloss, high fluidity, heat resistance, medium impact toughness and fine processability. The utility model is suitable for making household appliances (rice cookers, vacuum cleaners, electric irons, etc.), office equipment, instruments and meters, beauty equipment, etc..
- Q: What are the criteria for the classification of plastic materials at injection molding and extrusion?
- Plastic material is injection molding or extrusion grade, there is no standard, but there is an applicable reference value, that is, the material "melt flow rate" value.
