Q:What is cleaner for plastic bathtub?
Expired milk can not drink, can be placed inside a rag soaked, used to wipe, can quickly remove dirt.
Q:What are the distinguishing features of plastics? What is their chemical name?
PE) and linear low density polyethylene (LLDPE). Among the three, HDPE has better thermal, electrical and mechanical properties, while LDPE and LLDPE have better flexibility, impact and film forming properties. LDPE and LLDPE are mainly used for packaging film, agricultural film, plastic modification, etc., and HDPE is widely used in many fields, such as film, pipe, injection, daily necessities and so on.
Q:What are the raw materials used in the production of plastic products?
The poisonous and harmful substances produced by plastics of this kind of material come from 2 aspects. One is the single molecule vinyl chloride which is not completely polymerized in the process of production, and the other is the harmful substance in the plasticizer (two). These 2 substances in the high temperature and fat when easy to precipitate, toxic substances enter the human body with food, easy to cause cancer. At present, the containers for this material are less used for packaged food. If the family has this kind of material, don't let it heat.
Q:What plastics are environmental protection materials now?
Biodegradable plastics and water degradable plastics are environmental friendly materials.
Q:Types and uses of agricultural plastic products?
Since the production of agricultural plastic film, China has made two first in the world, that is, production first and covering area first. It is roughly 1.6 times as much as other countries in the world. According to incomplete statistics, at present the whole industry with the production of plastic sheeting 1000 enterprises, production capacity of 2 million tons, one million tons of annual production capacity of about 60 enterprises, large-scale backbone enterprises around 30, its production capacity and annual output accounted for 60% of the total. Film in consumption has reached 700 thousand tons, covering an area of 50 million acres; film annual sales of about 450 thousand tons, covering an area of 220 million acres or more; the actual consumption of agricultural film has more than 1 million 200 thousand tons.
Q:What are the parts of plastics and what are their characteristics?
The so-called plastic, in fact, it is a kind of synthetic resin, the shape of the natural resin with pine resin similar to, through chemical means of artificial synthesis, and is called plastic.
Q:What are the main features of plastics?
Plastic is a kind of synthetic polymer with plasticity. With synthetic rubber and synthetic fiber, it has become the three most important synthetic materials in daily life.
Q:Plastic products in the injection process should pay attention to what?
When the material is formed, the molten material contacts the cavity surface and the outer layer is cooled immediately to form a low density solid shell. Because of the poor thermal conductivity of plastic, the inner part of the plastic part is cooled slowly to form a large solid layer with high density. Therefore, the wall thickness, cooling slow, high-density layer thickness is large contraction. In addition, the layout and number of inserts have direct influence on the direction of material flow, the density distribution and the shrinkage resistance. Therefore, the characteristics of plastic parts have great influence on the shrinkage size and direction.
Q:Electric kettle is plastic, okay?
In addition, plastic electric kettle, only the outer shell is made of plastic, the liner is used in stainless steel, but the electric kettle in the heating process, the stainless steel liner temperature will become very high, the external plastic shell may appear a little taste in the heat, but this kind of the taste is very slight, generally do not produce what harm to the human body.
Q:White plastic products used for a long time and yellow, how do?
Yellowing time is not long plastic, you can use detergent powder scrub. It would be better to remove the yellowing layer on the surface. If all has been yellowed, yellowing of the product is generally unable to reply to the original white.
