Q:What additives are used in plastics?
The main requirements for plastic additives are: high efficiency: can effectively play its functions in the plastics processing and application. The comprehensive performance requirements should be based on the selection of additives mixing. The compatibility with synthetic resin better compatibility. The persistence: volatile in plastics processing and application process no exudation, does not migrate, dissolution. The chemical stability: no decomposition in plastics processing and application process, and the synthetic resin and other components of chemical reaction. The non-toxic, without any toxic effects on the human body. The price is low.
Q:How can a plastic foam be used?
The use of foamed plastics to life, plastic products have a very wide range of applications, especially in packaging and new materials, it has a very good use. The utility model can recycle and save energy, and can not cause white pollution to the environment. Can make all kinds of new materials: plastic foam box, gasket sheet, insulation insulation material, plastic foam board, etc., with surface buffering, heat preservation, rust prevention, moisture-proof, waterproof, breathable and so on.
Q:What is the pungent smell of plastic products?
Most plastics are made of PP or PE, which are non-toxic and harmless and have no pungent tasteSome plastics, such as PVC, have chlorine in the molecular structure and produce a small amount of HCl during the process, so they have a sour flavorThere may also be stains or impurities in defective plastics. If sulfur is present, the possibility of producing sulfides is not ruled out
Q:New plastic products have a strong taste, how to remove?
Adsorption method: let the plastic contact soak in the right amount of milk, vinegar, baking soda, salt water, waste tea, rice or rice water, grapefruit peel and pineapple block (good quality), liquor, dilute sulfuric acid (quality of time) and other cleaning agents, after a certain time can remove part of taste.Now the supermarket also has a lot of activated carbon air purification package sold, put plastic in it can also remove the flavor, the smaller the activated carbon particles, the better the adsorption effect. But note that carbon packs need to be removed from the sun for a period of time in order to expel toxic substances.
Q:How to make plastic products soft?
This is actually very simple, you can put him in the heating on a small would like or use hot water but this is useful if you want to be a short time long time it is very difficult because the weather is cold now, so it is hard to soft the other day will be better if you don't is not how love feeling if I still advise you to buy a good very soft
Q:What is the role of calcium carbonate in plastics?
Improve the processability of plasticsThe addition of calcium carbonate can change the rheological properties of plastics. Calcium carbonate powder, in addition to the amount of often larger, which will help it and other components of mixing, but also help plastic processing forming.
Q:White plastic products used for a long time will be yellow, how to do?
Plastic products aging, color will increase, yellowing of plastic products can no longer be white.
Q:Can I marinate salted eggs with a plastic bucket?
Lead salt antioxidant of polyvinyl chloride (PVC) products and ethanol, ether and other solvent exposure will lead precipitation. Lead salt of PVC as a food packaging and Deep-Fried Dough Sticks, fried cake, fried fish, cooked meat products, cake snacks foods to meet, will lead to molecular diffusion into the grease, so can not use PVC plastic bags containing food, especially food containing oil.
Q:Do plastic products contain toxic substances?
Can not say both, more in favor of ystm's statement.Some plastic products are non-toxic, such as water cups, etc., but some plastic products are poisonous, for example, plastic bags will not be solved.Still have specific plastic concrete analysis, is.I work in Tai'an modern plastics Co., Ltd., mainly providing plastic geogrid and other materials
Q:What are the advantages and disadvantages of plastics?
The density of plastic is between 0.8-2.2g/cm3, generally only steel 1/3-1/4, aluminum 1/2, concrete 1/3, similar to wood. It can reduce the construction intensity and reduce the weight of the building.
