Q:When was plastic invented?
Advantage1., most of the plastic corrosion resistance, and not with acid, alkali reaction.2. plastic manufacturing costs low.3. durable, waterproof, light quality.4. easy to Suzhi into different shapes.5. are good insulators.6., plastics can be used in the preparation of fuel oil and fuel gas, which can reduce oil consumption.shortcoming1., the recycling of waste plastics, classification is very difficult, but also uneconomical.2.. Plastics burn easily and produce poisonous gases when they burn. For example, toluene combustion produces a small amount of polystyrene, this substance can cause blindness, vomiting and other symptoms of inhalation, PVC combustion will produce toxic gases, hydrogen chloride in combustion, is a high temperature environment, will lead to plastic decomposition of toxic components, such as benzene etc..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.6. because of the inability of plastics to degrade naturally, it has become the number one enemy of mankind and has led to the tragedy of many animal deaths.
Q:How can lenses be made out of plastic or resin?
Of course, the resin can be divided into many types, you can do is not transparent lenses, transparency, refractive index and wear resistance have higher requirements, like ordinary glass can do glasses, optical glass must be dedicated to. Although glasses are profiteering products, but the quality of high-grade lenses will be much cheaper than the quality
Q:What plastics are environmental protection materials now?
Water degradation plastic: adding water absorbent material in plastic, when used up, it can be dissolved in water. It is mainly used in medical and sanitary equipment (such as medical gloves), so it is easy to destroy and disinfect.
Q:What are the main defects of common plastic products?
Warpage, deformation: due to forming residual stress, shear stress, cooling stress force and uneven shrinkage caused by insufficient cooling, demoulding; bad, plastic products, insufficient strength, mold deformation and other reasons, the plastic products shape distortion and warpage from Kong Pian, such as the phenomenon of uneven wall thickness.Crack: due to plastic stress is too large, poor cooling, demoulding unevenness, poor performance of plastic or plastic products of poor design and other ills (such as deformation) and other reasons, make plastic products surface and feeding additional fine cracks, or cracking or in the load and the effect of solvent cracking phenomenon.Black spot, a plastic material or due to decomposition of combustible volatiles and air combustion decomposition under high temperature and high pressure combustion with the melt into the cavity, showing black spots, black stripes on the surface of plastic products, plastic products, or along the surface is like carbon burn phenomenon.
Q:Do all plastics have plasticizers?
Plasticizer is divided into toxic and non-toxic, relieved, and now the plastic basically useless toxic plasticizers, and generally do not contain phthalate two formic acid
Q:How do you glue a broken plastic basin?
Find you a soft plastic, burn it, drop the drop of plastic in the dew place!!
Q:Plastic shoes taste great, is it harmful?
But if the smell of plastic shoes is too strong and smells long, there will be smoke and dizziness, which is likely to contain substances harmful to human body.
Q:Do plastic products contain toxic substances?
Plastic products for daily use are not toxic, and paper, paper no poison, but the papermaking process will produce pollution, and the use of some toxic substances. Toxic part of manufacturing plastic raw materials, plastic products but is a polymer material, not toxic, but does not rule out some unscrupulous businessmen in the plastic material or add some excess recovery assistant.
Q:What if the plastic is broken?
The ultrasonic melt method is effective for thermoplastic resin products, and can be processed at high speed, and the shape can be arbitrary.
Q:How to remedy plastic deformation?
This is a bar of iron, but iron bar has also been beating can recover the original straight, but shaped object is more difficult. Speak understand the truth, more trouble, but we can understand in this way, objects when temperature changes, the distance between the molecules is changed, then the temperature recovery after the distance between the molecules can also restore the original value, but the spatial arrangement of molecules is different,
