Q:Why should I granulate before injection? What's the advantage of granulation?
Direct crushing material can also be used, but the direct crushing of the material due to uneven particle size, resulting in uneven storage process, the process becomes more unstable. And granulation, the particles are generally more homogeneous, and later injection molding process is relatively stable! As for the difference between granulation and injection: This is the two process, granulation is a number of waste plastics through melting, extrusion, in the cutting machine to cut into granular. During the granulation process, some additives can be added to improve the performance of waste plastics. Something like a toughening agent. Plastic injection is the formation of plastic products by melting the plastic material and then by pressing it into the mold. Popular to say is: injection molding is the raw material into plastic products, and granulation is to make plastic products again "raw material""!
Q:Does high strength polyurethane belong to plastics?
Rubber and plastic are juxtaposed terms, no one belongs to anyone.
Q:What is the most effective way to reduce the environmental pollution caused by plastic bags?
First, strengthen management.Two, prohibit the use of disposable biodegradable plastic packaging.Three, forced recycling.
Q:Is the plastic box good or the glass good?
Glass preservation boxIt has toughened glass preservation box and heat-resistant glass fresh-keeping boxAdvantages: material safety, high transparency, heat-resistant glass can withstand high temperature.Disadvantages: high temperature tempered glass will crack, heavy fragile products, should not carry, tightness is not good.
Q:What are the raw materials used in the production of plastic products?
Common mineral water bottles and carbonated beverage bottles are made of this kind of material which can not be recycled or hot water. Its heat-resistant temperature is only 70 degrees, only suitable for warm drinks or cold drinks, high temperature liquid or heating, easy to deformation, will dissolve the harmful substances. The scientists also found that the plastic could release carcinogens in 10 months. Therefore, when the beverage bottle is used up, it should be thrown away. It should not be used as a drinking cup or used as a storage container to hold other foods, so as not to cause health problems.
Q:The plastic basin is broken. How do you fix it?
Tonic! It's like a candle stick. Take it on the fire and place it in a plastic pot. Just press it for a while
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:How can you increase the hardness of PE plastics?
Use of polyethylene plastic stiffening agent. The chemistry and physics of the special effect, in the use of a small amount of conditions, can effectively increase the PE plastic, including LDPE, HDPE, PE flame retardant PE, mineral filler and reclaimed PE plastic hardness, flexural modulus and mechanical properties, suitable for various molding process and plastic products such as pipe, sheet, injection molding products, the use of convenience, safety and environmental protection, by Ma'anshan Keli chemical technology development and production company. In addition, there are ABS plastic reinforced agent and PP plastic reinforced rigid agent and so on. They have the same function.
Q:What are the benefits of plastic bags? What's the disadvantage?
Plastic bags not only bring harm to human beings, but also pose a threat to the survival of animals. The sheep love parade residue to eat in a plastic bag wrapped folder, but often even plastic bags together to eat it, because the plastic long time eat stranded in the stomach to digest, the stomach was filled with sheep, can not eat, can only be finally starved to death.
Q:White plastic products used for a long time and yellow, how do?
Generally white white plastic in the injection molding to add whitening powder material, so that after the injection molding products will be white jade. After a period of time, the whitening powder will lose whitening effect under the action of sunlight, so it will make the product yellow.
