Q:Scope and characteristics of plastics No. 7
Plastic No. 7 represents polycarbonate (PC), other plastic products. PC is a widely used material, especially for bottles and space cups, which is controversial because it contains bisphenol A. Experts point out that, in theory, as long as the process of making PC, bisphenol A percent into plastic structure, it means that the product is not bisphenol A, let alone release. However, if a small amount of bisphenol A is not converted into a plastic structure of PC, it may be released into the food or drink.
Q:Can I marinate salted eggs with a plastic bucket?
In addition, PVC plastic products at higher temperatures, such as 50 degrees or so, will slowly decompose hydrogen chloride gas, this gas harmful to humans, so PVC products should not be used as food packaging. Bakelite (bakelite) containing phenol and formaldehyde, have certain toxicity to the human body, is not suitable for the storage of food and food packaging. Electric jade (urine aldehyde plastic) although odorless, but at 100 degrees of boiling water or vinegar for containing food, there will be precipitation of free formaldehyde, harmful to the human body, so it is not suitable for food or food packaging. Waste plastics (some may add a little new material) update, because of its complex composition, it is difficult to guarantee that no toxicity, it is generally not used as food containers and packaging.
Q:What's the difference between memory plastic and sheet metal?
Plates, glasses frames, Han Gaa In glassesMaterial: made of high-tech plastic memory plate.
Q:How do you repair the plastic surface that scratches?

Q:Plastic products 2 can hold hot thing?
The dangers of indiscriminate use of plastic products to hold food seem to have aroused the attention of people and society.

Q:Is ABS plastic poisonous?
Of course, due to the application of different plastics will add different additives, but the difference is very big. Different plastic plastic additives are generally inorganic filler, glass fiber, pigment, antioxidant, anti UV agent, plasticizer and inorganic filler and glass fiber. The body is stable and has no toxicity to the mineral glass. The human body. The antioxidant and anti UV agent general dosage is small, but 1-2% of the components, of course the nature itself is non-toxic or low toxic to the human body. The most likely risk of plastic is PVC, the plastic additive content could even reach 60-70%, it is difficult to ensure there is no harm to human body.

Q:Plastic parts are easy to crack under what conditions
Mold aspects:(1) the top should be balanced, such as the number of the top and the section area to be enough, the mold slope should be enough, the cavity surface should be smooth enough, so as to prevent the external force caused by the residual stress concentration and cracking.(2) the structure of the parts can not be too thin, and the transition part should use the arc transition as far as possible to avoid the stress concentration caused by sharp corners and chamfering.(3) as far as possible less metal inserts, in order to prevent the inlay and parts shrinkage rate, resulting in increased internal stress.(4) deep parts shall be provided with proper release air inlet holes to prevent vacuum negative pressure.(5) the main runner is enough to release the sprue when the sprue is not ready to be cured so that it can be easily removed.(6) the main runner shall be joined with the nozzle to prevent the delay of the chill material and cause the parts to adhere to the fixed die.
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.
