Q:How do plastics weld?
Bonding can achieve good performance and good quality joints, but it is difficult to operate. It needs careful preparation of joints and surfaces, and it is very slow and unsuitable for mass production. The welding is economical, simple, fast and reliable, and can form static strength close to the parent material. Therefore, it is suitable for mass production, and has gained more and more extensive application in the automobile industry. The level of plastic welding technology has become one of the marks to measure the level of automobile production technology and new material development.
Q:What is the best plastic welding method?
Hot plate welding mainly used similar thermoplastic plastic welding, easy to control the same plastic melting temperature, the temperature control of the heating plate of the same relatively easy, simplify the difficulty of manufacturing the heating plate; for different types of plastic welding, the influence of temperature difference between the two plastic, must increase the difficulty of manufacturing and processing the heating plate, there will be insufficient strength.
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:Can plastic bottles be recycled?
People are often used to drink bottles, mineral water, bottled water to drink. Some consumers feel strange when they drink plastic bottled drinks. Taste change is mainly because of plastic packaging for the beverage by the sun exposure after a particularly hot summer, the plastic bottle is easy to produce odor, some people think that this with a plastic bottle logo: consisting of three arrow triangle, the number 1-7 in higher numbers marked more heat resistant bottle. A triangle consisting of three arrows
Q:How do you dye plastics?
The method of extrusion is to mix the dye and the plastic by dry dyeing, then crush it into a thin strip with a special extruder and cut it into granules. The method is well blended and helps to disperse undesirable pigments
Q:Is there a difference between recycled plastics and new ones?
Polyvinyl chloride: more obvious discoloration after regeneration, once after the extrusion will have a light brown, and three times almost become opaque brown. The specific viscosity is unchanged at two times, and tends to decrease more than two times. Both hard and soft PVC shall be joined with stabilizers. In order to make the product shiny, ABS 1% - 3% can be added when recycled.
Q:What material is better for plastic cups?
5 is better than PP.The cup has high temperature resistant materials, such as PC, AS, PP.TRITAN, ECOZEN. PC is banned in bottles and some space cups in Europe and america. AS too crisp; PP cost-effective, environmental protection, transparency and feel bad. TRITAN and ECOZEN are currently in the domestic manufacturers do not have the domestic market, export orders, but also environmental protection, does not contain BPA, transparency and feel and equal to PC, the price is high, the daily use of PP can, or glass.
Q:How to make up the holes in the plastic basin, and the method is simple and durable
Another method is to press a piece of plastic on a leak. Use a hair dryer to blow the hot air between the plastic sheet and the basin. Press it gently after melting. Be careful, or you'll blow a hole in the plastic basin.
Q:What if the plastic is broken?
The screw connection is effective for thermoplastic resin products, which can be processed at high speed and can be arbitrarily shaped.
Q:The use of various plastic materials?!
GPPS modified polystyrene 204The transparency of 88-92%, refractive index 1.59-1.60, suitable for light products, dyeing is strong, non-toxic and tasteless, no fungus growth, high impact strength, resistance to acid and alkali resistant performance is good, not on the basis of solvent, excellent electrical properties, easy molding, moisture less than 0.02% can maintain the strength and size of high humidity, but the brittleness.Suitable plastic products: decorations, lighting signs, lampshades, stationery, transparent toys, daily necessities, instrument lenses, freezers and thermal insulation in the refrigerator (after foaming).
