Q:What additives are used in plastics?
Plastic additives according to their specific functions can be divided into seven categories: the additive to improve the processing performance, such as heat stabilizer and lubricant additives. The improved mechanical properties, such as plasticizer, toughening agent. The additives to improve the surface properties, such as antistatic agent, coupling agent and other additives to improve the optical performance., such as coloring. The Additives Improving the aging properties, such as antioxidant and light stabilizer. The lower the cost of plastic additives, such as extenders and filler. The effect of additives with other specific, such as foaming agent, flame retardant, preservatives and so on.
Q:How to make plastic products soft?
Heating, hot water, hot air can be generally around seventy degrees began to soft
Q:How many kinds 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.PP: the name for polypropylene, five-star pin, handrails, floor mats and high strength is not necessary connections. Disadvantages: poor wear resistance and low surface hardness.PVC Name: PVC, mainly used for sealing, inserted conditions. It is adapted to extrusion molding, and PVC material is the material does not burn plastic parts, processing temperature stability, especially the stability of the color is not good.
Q:Made of plastic masterbatch high temperature fade, stick to the other items, how this color
This is a common problem of low price is like this to the best way to improve this phenomenon is the use of some of the high price of Masterbatch
Q:How do you understand the level of engineering plastics?
Representative PS (polystyrene): This is used to make bowls, instant noodles boxes, foam snack box material, heat resistant, cold resistant, but can not be put into the microwave oven. Can not be used to hold strong acids (such as Liu Chengzhi), strong alkaline substances.
Q:How can plastics be produced, In several ways?
Extrusion, also known as extrusion molding, is the use of extruders (extruders) to heat the resin continuously through the mold extrusion of the desired shape of the product. Extrusion is sometimes also used in the forming of thermosetting plastics and can be used in the moulding of foamed plastics. The advantage of extrusion is that it can extrude various shapes of products. The production efficiency is high, it can be automated and continuous production. The disadvantage is that thermosetting plastics can not be widely used in this process, and the size of products is prone to deviation.
Q:What is the difference between plastic PP1, PP2, PP3 and PP4?
PP1 plastic centrifuge tube is made of PP material, without toxicity and chemical tolerance. PP2 heat resistant aging. PP3- use overview: endoscope casing, left and right toolbox, door handle remarks: weathering, heat aging.
Q:What are the benefits of plastic bags? What's the disadvantage?
Disadvantages: plastic bags will not only affect the development of agriculture, but also great harm to the land, so that the land to change its pH, affecting crops to absorb nutrients and moisture. There are plastic bags are thrown into some of the wasteland, if these plastic bags recycling, processing, and then new use, then magazines and additives more, the people's physical harm will be greater.
Q:How many grades are there in the plastic block? How to divide?
Flame retardant grade bottom HB:UL94 CSA and C22.2 No 0.17 standard, requirements for 3 to 13 mm thick sample, the burning rate is less than 40 mm per minute; less than 3 mm thick sample, the burning rate is less than 70 mm per minute; or extinguished in 100 mm signs before.V-2: the flame was extinguished in 60 seconds after the two and 10 second combustion test of the sample. A fire can fall off.V-1: the flame was extinguished in 60 seconds after the two and 10 second combustion test of the sample. No fire can fall.V-0: the flame was extinguished in 30 seconds after the two and 10 second combustion test of the sample. No fire can fall.
Q:What type of plastics do you have?
Plastic refers to the organic synthetic resin as the main ingredient, added or not with other materials (additive) and artificial material. It is usually in the heat and pressure under the condition of plastic devices made with a certain shape. Plastic is a synthetic high molecular organic compounds with plasticity.
