Q:What do you mean seven and five under the plastic cup?
Common use: cleaning products, bath products, white bottles, skin care products packaging.The use of plastic bags in supermarkets and shopping malls are made of such material, resistant to high temperature of 110 DEG C, indicating the food use of plastic bags can be used for holding food. Bearing cleaning supplies, plastic containers and bath products can be repeatedly used after careful cleaning, but these containers are usually not good cleaning residue, the original cleaning supplies, become a breeding ground for bacteria, cleaning is not thorough, it is best not to use circulation.
Q:What does plastic melt mean?
The melt flow rate instrument is a test facility for measuring the melt flow rate of thermoplastics under certain conditions. The melt flow rate is an index to measure the melt flow of plastics. The higher the value, the better the melt fluidity of the plastics.
Q:How do you repair the plastic surface that scratches?
Plastic scratches are repaired in the following ways:1, gently wipe with oil, scratches will not be so clear;2. Polish with car wax;3, buy plastic products special polishing agent, polishing principle is slight grinding, will make plastic thin.
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 most effective way to reduce the environmental pollution caused by plastic bags?
First, take the paper instead of plastic. At present, our country also has the practice of producing disposable tableware with cane and straw as raw materials, but it is still in the experimental stage.Two, biodegradable plastics are adopted.
Q:What are the advantages and disadvantages of plastic packaging materials?
Secondly, the plastic material has a very suitable barrier and permeability, you know, in plastic packaging, there is gas barrier packaging. Moisture proof packaging, waterproof packaging, and all kinds of fresh fruit packaging. These are plastic packaging to meet the respiratory effects of fresh ingredients. Again, the optical properties of plastic packaging is very good, because the plastic packaging materials can be made transparent, so when it is made of packaging containers, for which we see the contents of the indirect effect of crystal clear, very good promotion way.
Q:Can plastics be recycled?
Thermosetting plastics can be divided into two types: formaldehyde, cross-linking and other cross-linking. Another category is thermoplastics, which refer to plastics that have heating, softening, and cooling hardening properties. Most of the plastic used in our daily life falls into this category.
Q:What are the main defects of common plastic products?
Poor welding: due to the melting of material, the drop of the material temperature at the confluence, the failure of the resin and the inclusion compound, etc., causes the welding material to flow into the confluence and the welding is bad and produces a fine fine seam along the surface or inside of the plastic product.Because of the melt along the surface of the mold surface is not smooth flow to fill the cavity, but into a semi solidified state of fluctuation along the cavity surface of the melt flow or a stagnation phenomenon.Silver markings: as the material in water or air, and volatile matter too much, the melt shear effect is too large, the melt and mold surface sealing side, or rapid cooling or mixing of different materials or decomposition of metamorphism, and make plastic products surface appearance of silver white luster along the direction of flow of the needle like stripes or mica makeup markings (water traces).
Q:What kind of plastic can touch food?
It is better to wear plastic without color. The color is usually processed and not clean!
Q:Plastic products after melting, dip in the pot bottom, how to remove?
Because of plastic and steel products, the coefficient of thermal expansion and contraction is different. Who experts even think, but should first heat the pot, very easy to rust. Pour some hot water into the greasy pan later and heat the pan.
