Q:What kind of plastic material is special for microwave oven?
Use: the only plastic box that can be placed in a microwave oven. It can be reused after careful cleaning. Special attention should be paid to some microwave oven boxes. The box is made of No. 5 PP, but the box cover is made of No. 1 PE. Because the PE can not withstand high temperature, it can not be put into the microwave oven with the box. For insurance purposes, put the container in front of the microwave oven and remove the lid first.
Q:What's the difference between plastic bags 02 and 00?
Ordinary plastic bags and plastic tableware involve the problem of "white pollution", which is not decomposed at the ground floor, and is harmful to crops, water sources, livestock and human beings themselves. While biodegradable plastic products are buried in the soil, because the surrounding environment can meet the requirements of decomposition, it will be completely decomposed into carbon dioxide and water, belonging to the organic cycle, harmless to the human body and the environment.
Q:Why plastic is not environmentally friendly?
3. plastics are made from petroleum refining products, and oil resources are limited.4. plastic buried in the ground for hundreds of years, thousands of years or even tens of thousands of years will not decay.5., the heat resistance of plastic is poor, easy to aging.
Q:How long is the shelf life of plastic bottles?
EPE Quality Supervision Bureau of Shanxi Province Quality Supervision Bureau staff said, at present our country has no unified relevant standards, only industry standards. Some bottles of foreign production, although the label for a period of 10 years, but after repeated use, especially high temperature after heating, will release toxic substances bisphenol A, so as not to use heating, not straight in the sun. At present, our country adopts triangle symbol as plastic recycling mark. It can remind consumers to use it correctly from material. EPE staff said that at the bottom of the plastic bottle, there is a triangle with 1 - 7 numbers inside it. Each number represents a different material, indicating what kind of resin the product is made of. Such as for the manufacture of bottles, space cups and other ingredients containing PC plastic products, more marked as "pearl cotton 7EPE", "mineral water bottles", "carbonated drinks bottles" and more marked as "pearl cotton 1EPE".
Q:What is the role of calcium carbonate in plastics?
Improve the hardness and rigidity of plastic productsIn plastics, especially in soft PVC, the hardness increases with the amount of calcium carbonate, and the elongation decreases with the increase of hardness. Particle size, oil absorption value of calcium carbonate, hardness growth rate. Conversely, the particle crude oil absorption value of small calcium carbonate, plastic hardness growth rate is small. In soft PVC, calcium carbonate (light) is the next to the lowest hardness growth rate of heavy calcium carbonate.
Q:How can you increase the hardness of PE plastics?
Is it HDPE or LDPE? You can add some calcium carbonate to improve the hardness.
Q:What do you mean by the release angle of plastic parts?
Inclination direction. In the small end hole to prevail, meet drawing requirements size, inclination to expand direction; shape is as big as the standard, to meet the requirements of drawings, to obtain small inclination direction. Generally, the stripping slope. Without the limitation of the tolerance zone of the product, the release inclination of the high precision plastic products should be within the tolerance zone.
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:Types and uses of agricultural plastic products?
According to the division of agricultural plastic application areas are mainly agricultural covering materials; agricultural water supply pipeline and water saving equipment; plastic packaging materials and agricultural planting, breeding, storage with various materials. Agricultural film is the most important component of China's plastics industry, and it is an important means of production in the development of modern agriculture
Q:What about the outlook for plastic particles?
A medium-sized plastic woven bag factory annual consumption of more than 2000 tons of recycled polypropylene particles, even individual small factories are required minimum annual consumption of hundreds of tons; a medium-sized shoe factory in need of polyvinyl chloride (PVC) recycling 2000 tons of recycled plastics enterprise...... particles of huge demand, provide a broad market space for enterprises and individuals to establish the regeneration of the waste plastic particles factory. As a result, recycled plastic particles do not worry about sales.
