Q:How to mend cracks in a plastic bucket?
AB is a nickname for the two liquid mixed hardening glue, the glue is a liquid, a liquid hardener, two feed to hardening, is not required by the temperature should be hard ripening, so it is a kind of adhesive curing at room temperature, the model is sometimes used to do. Generally used in industry.
Q:How do plastics weld?
Plastic connection is the key link of its extensive application. Plastics can be connected by mechanical fastening, bonding, or welding. Fastening, fast connection, suitable for all plastics, but high cost, will produce stress concentration, can not form sealed joints or get the appropriate performance.
Q:How do you dye plastics?
This method is basically the same as the extrusion dyeing method. The difference is that the proportion of the dye in the plastic is 10 times higher than that of the usual one. It can be used more frequently when the plastic is injected
Q:Plastic shoes taste great, is it harmful?
But if the smell of plastic shoes is too strong and smells long, there will be smoke and dizziness, which is likely to contain substances harmful to human body.
Q:Advantages of plastic furniture
Various varieties and wide range of applicationsPlastic furniture is not only applicable to public places, but also to ordinary families. In public places, is a variety of chairs you see the most, and is suitable for family varieties are too many to count: dining table, dining chairs, lockers, racks, shoe racks, flower. 5, easy to clean, easy to protect, plastic furniture dirty, can be washed directly with water, simple and convenient. In addition, plastic furniture is relatively easy to protect, the indoor temperature, humidity requirements are relatively low, widely applicable to a variety of environments.
Q:What do you mean seven and five under the plastic cup?
This kind of plastic is good in plasticity and cheap in price; it can not be packaged food. The poisonous and harmful substances produced by plastics of this kind of material come from two aspects. One is the single molecule vinyl chloride which is not completely polymerized in the process of production, and the other is the harmful substance in the plasticizer (two). These two substances are easy to precipitate when they encounter high temperature and fat. Toxic substances enter the human body with food and cause cancer easily.
Q:How much is plastic PP5 resistant to cold?
Ordinary homopolymer PP has higher heat resistance, but when it reaches -20 degrees of low temperature, it will not stand, easy to brittle.
Q:What harm does plastic particles do to the body in the factory?
Factory waste affects the respiratory tract for a long time, and reduces local resistance. It can cause local invasion because of decreased immunity.
Q:What if the plastic is broken?
Hot melt bonding (plastic welding), hot melt, also known as plastic welding, is the basic method of thermoplastic connections. Plastic welding is the process of heating plastic products at the bonding place, melting them, and then connecting the two products into a whole after cooling.
Q:How can the strength and toughness of plastic products be tested simply?
According to the chemical composition of different plastics, the plastic reinforcing agent can improve the strength of the plastics by corresponding chemical action. Mainly used in a variety of modified plastics (including glass fiber reinforced, flame retardant, halogen free flame retardant, mineral filling, etc.) and common (including recycled) plastic. Different types of plastics are suitable for reinforcing agent, modified PP, PE, ABS, HIPS, PBT, PA, PC/ABS and other plastic varieties, in the use of a small amount of conditions, can significantly improve the mechanical strength and impact strength of plastics and plastic products. Suitable for all kinds of plastic molding methods and all kinds of plastic products. Ma'anshan Keli chemical technology development and production company.
