Q:What are the plastic bags made of?
General civilian products, mostly polyethylene (PE) to do, PE is divided into low pressure high-density HDPE, low pressure high-density LDPE and linear low-density LLDPE
Q:What's the shell of the relay? What exactly is plastic?
It is by virtue of this characteristic of molding, the use of the first heating of the plastic flow, under pressure filled cavity, and then solidified into a shape and size of the product. Thermosetting resins are linear or branched before curing, forming a chemical bond between the molecular chains after curing, becoming a network of three degrees, not only without melting, but also insoluble in solvents. Bakelite, formaldehyde, melamine, formaldehyde, epoxy, unsaturated polyester and silicone plastics are all thermosetting plastics. Mainly used for heat insulation, abrasion resistance, insulation, high voltage resistance in the harsh environment of the use of plastic, mostly thermosetting plastic, most commonly used should be wok, pot handle and high and low voltage appliances.. Commonly used thermosetting plastics are phenolic resin, urea formaldehyde resin, melamine resin, unsaturated polyester resin, epoxy resin, silicone resin, polyurethane and so on
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.
Q:What can recycled plastics do?
The source of waste plastic materials, where there was a waste plastic, easy to buy, cheap (around, so) a city daily consumption of plastic bags and other plastic products reached more than 10 tons in rural areas have a lot of plastic waste plastic particles Recyclable, don't worry about sales. Suitable for partnership enterprises, laid-off workers and individual production. Gong Zhen Xiao Mao CI is the history of Chin Shan recycled plastic base professional manufacturer and supplier. Hedong District, Shandong City, Linyi province has built the largest national renewable plastic base in china.
Q:What is the difference between PA66 and PA6 plastic raw materials? Differences in price, color, performance, etc
PA66 (polyamide 66 or nylon 66) is more widely used in the automotive industry, instrument shells, and other products that require impact resistance and high strength than PA6, PA66.
Q:What is the difference between ABS plastic raw materials and recycled materials? Or how to distinguish between raw materials and recycled materials?
1. recycled material is not natural (ABS is yellow).2. non black pellets with black spots are recycled.3. the impurity in the aggregate is the recycled material.4. of the voids in the pellets are recycled.5. do MFI test, the result is more than 10% of indicators are recycled material.6., feed heating, smell, smoke, melting temperature is low, fast flow is recycled material.
Q:What does MFI mean in PC material?
The measurement of MI is usually based on the standard method of ASTM D1238. It is the principle of the plastic or resin into the metal sleeve of a fixed inner diameter, and heating the plastic or resin after melting, and then give some load on the piston, the piston on the weight of the molten plastic has been squeezed out from a small hole in the charge, and calculate the weight and squeezed out of plastic. This measuring method, because of the same material, the sleeve barrel inner diameter, load, and temperature are fixed, so in addition to test MI, can also be used for the determination of density, viscosity, and melt shear rate, shear stress... etc.
Q:Raw materials for making plastic bags
For the identification of PVC plastic bags and polyethylene plastic bags, the following simple methods are used for identification. Polyethylene film (non-toxic) film is milky white, translucent (a few stacked observation especially), feels like a lubricant is coated on the surface of a layer of wax, shaking, crisp sound, fire flammable, flame yellow, burning mucus dripping, and the candle burning smell.
Q:How about the price of plastic raw materials now?
Businesses still adhere to prudent operation, mainly with quotations in the market, and more wait-and-see mentality.
Q:What raw material (HDPE) made of plastic bags, high transparency, good sense of light master?
Fillers, also called fillers, can improve the strength and heat resistance of plastics and reduce costs. For example, adding wood powder to phenolic resin can greatly reduce the cost, and make phenolic plastic one of the cheapest plastics, and can also significantly improve the mechanical strength. Packing can be divided into two kinds of organic fillers and inorganic filler, the former such as wood powder, rags, paper and all kinds of fabric, the latter such as glass fiber, diatomite, asbestos, carbon black.
