Q:How about making a bottle of yogurt with plastic bottles?
The best selection of high temperature resistant plastic bottles or containers, because in the production of yogurt is fermented, fermentation temperature is about 40 degrees, if the plastic containers used under high temperature will release harmful substances, which is harmful to health, high temperature resistant plastic products will not have this phenomenon, for example plastic products, microwave oven suitable, or other ceramic products or glass containers.
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 are the grades of plastics from 1 to 7?
In order to facilitate the regeneration of various post consumer plastic products will need to use different kinds of plastic sorting, because the plastic consumption channels and more complex, some post consumer plastic and it is difficult to simply be distinguished by the appearance, therefore, the best in the plastic products marked material varieties.
Q:What does "stress hardening" of plastic molding mean?
Plastic stress hardening phenomenon, refers to the plastic molding process, with the orientation of the increase of intermolecular forces increased, causing the polymer viscosity, the polymer showed "hardening" tendency, the deformation tends to be stable and no development. This phenomenon of orientation process becomes "stress hardening"".
Q:Has the plastic bottle been poisoned for a long time?
01 stands for PET (polyethylene terephthalate), most commonly used in the manufacture of mineral water, carbonated drinks and other bottled beverages. As we all know, the beverage bottles made of this material can not be hot water, only suitable for warm drinks or frozen drinks, high temperature liquid or heating, it is easy to deformation, the dissolution of harmful substances. Scientists also found that the use of the plastic could release carcinogens after more than 10 months. Therefore, it is recommended that the beverage bottle be discarded and no longer used as a water container or a storage container.
Q:What happens when plastic gets wet and sticky?
The plastic is made of monomers as raw materials, polymer by polyaddition or polycondensation polymerization, can freely change the composition and form style, composed of synthetic resin and filler, plasticizer, stabilizer, lubricant, pigment and other additives.
Q:What are the parts of plastics and what are their characteristics?
The main component of plastics is resin. The term was first resin secrete by animal and plant lipid and its name, such as rosin, shellac, resin is not mixed with various additives and polymer compounds. Resin accounts for about 40% to 100% of the total weight of plastics. The basic properties of plastics depend mainly on the nature of the resin, but additives also play an important role. Some plastics are made up of synthetic resins, with or without additives such as plexiglass and polystyrene
Q:What does the plastics factory mainly produce?
Polyethylene is an organic plastic raw material ethylene by polyaddition reaction process, non-toxic, tasteless, light quality and good characteristics, is currently recognized by the world food and pharmaceutical packaging materials for plastic bags. The plastic packaging bags made of polyethylene mainly include ordinary polyethylene plastic bags, polyethylene high / low pressure plastic bags, polyethylene vacuum bags, etc. it is one of the most plastic packaging products in the world. Most of polyethylene plastic bags plastic products factory production for food and pharmaceutical industries, especially polyethylene production process using vacuum bag, vacuum principle that does not contain the composition of air bag, restricting the microbial environment, is the ideal material for food packaging.
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 harm does it take to eat hot food with plastic?
If a plastic bag containing more than 50~60 degrees of food is used, the lead in the bag will dissolve into the food, and the plastic bag will release poisonous gas and invade into the food. Long term intake of the human body can seriously impair health and cause disease. Especially hot food, high temperature will make the poisonous substances in plastic absorbed by food, once entered the body will cause accumulation of towel poison, so when the hot food, must not mess with plastic bags.
