Q:What is the material of plastic bottles? Will plasticizers be produced?
The stability of PET is determined by the degree of polymerization of the material. Generally, when the temperature is less than 120 degrees centigrade, the PET material is very safe. In addition to PET, plastics often used in daily use, such as PP and PE, do not add plasticizers. The addition of plasticizer in the making of PVC, PVC as the raw material for the production of some film, plastic film, children's toys, disposable gloves and other products, plastic additives products should be more strict selection of production enterprises, shall comply with the provisions of the relevant EU and national products of environmentally friendly plastics.
Q:How to classify waste plastics? Identification methods?
The rapid development of the plastics industry also brings a series of social problems caused by waste plastics, waste plastics and waste plastics which people are unwilling to see. Plastic products have been applied to every corner of society. From industrial production to basic necessities of life, plastic products are everywhere. People began to find that the plastic garbage has quietly come to us, seriously affect our health and living environment, such as agricultural land due to the impact of waste plastic and waste plastic production began, triggered by the "white pollution" to make people headache, not decay decomposition boxes can not be effectively recovered, with plastic life the garbage can not start treatment...... The sharp increase in plastic waste and the social and environmental problems caused by it are placed in front of people and placed in the place where people live and live all over the world.
Q:Waste plastics recycling plant how to solve environmental problems
Sources of waste plastics:Where there are people, there will be plastic waste. All kinds of plastic packaging, plastic film, shopping bags, woven bags, beverage bottles, plastic pots, plastic pots, plastic barrels, plastic toys, plastic stationery, plastic shoes, vehicle bumper, shells of home appliances, computer casings, waste PVC pipe, industrial waste plastic products, plastic doors and windows, polyester products (polyester film, mineral bottle of coke bottle) and plastic molding processing of waste and so on, can be seen everywhere, inexhaustible life and growth in nature!
Q:Is chlorine dioxide corrosive to plastic products?
NoThe chemical properties of plastic products are very stable. If they are corrosive, are we still worried about white waste? So chlorine dioxide is not corrosive to plastic products
Q:How do I see if the plastic cup is qualified?
As a result, the identification of plastic varieties has become simple and easy, and the cost of recycling has been substantially reduced. Today, many countries in the world have adopted the SPI logo scheme. China enacted almost identical labeling standards in 1996.
Q:Why can't we discard plastic products at will?
PVC (polyvinyl chloride), is rarely used for food packaging. It is best not to buy the use of this material: high temperature to produce harmful substances, even in the process of manufacturing it will release toxic substances enter the body with food, may cause breast cancer, congenital defects and other diseases. At present, this kind of material has few containers for packing food. Never use it if it is in use. "
Q:What are the common plastics??
Low density polyethylene (PE-LD or LDPE): common in cling film, plastic film. Low density polyethylene heat resistance is not strong, do not pack in the food surface into the microwave oven, usually in the temperature of more than 110 degrees when there will be hot melt phenomenon, will leave some of the body can not be broken down the plastic preparations.
Q:How can plastic paint be used to prevent paint falling off?
Spraying: plastic coating thickness of 15~20 m, usually painted 2~3 road to complete. Spray 15min dry and then spray second times. Bright surfaces must be painted with transparent paint. The painted parts have little influence on the flame retardance.
Q:Plastic products after melting, dip in the pot bottom, how to remove?
It melted with fire. I suggest you use bamboo brush later. I don't think the plastic is good
Q:What's the difference between cans and plastic bottles?
The glass bottle can be used repeatedly and is inconvenient to carry, but there are phenomena of cleaning up, cross contamination and fraud, and people can not be relieved.Plastic bottle, glass with respect to that of oxygen and carbon monoxide permeability coefficient is large, it will lead to a chemical reaction between packing objects and packaging, packaging is also due to the oxidation of the flavor deterioration occurred, and the aging of plastic products also affect the appearance quality, beautiful appearance and practicability, and environmental pollution.
