influence of plastic processing aid materials

Although the material is very common plastics processing generally, but supplies are essential in our lives. The growth rate of
China's plastics processing industry is extremely fast, especially closer to modernization today. Plastics processing industry in a
very rapid rapid development. Now a lot of WSD plastic additive  material wood and metal has its drawbacks and limitations, they produce slow, costly,
and now a lot of weight disadvantages such as wood and iron products and parts have been replaced by plastic products, such as we
often see articles toothbrushes, nozzles, cups, sandals, etc. are made of plastic. It can be said almost unlimited capacity to
replace plastic.
As you know, a lot of things have plastic processing aid expansion and contraction characteristics, when something temperature
increases his larger expansion of the molecular structure, its outward expansion of larger organizations, we will let him certain
items heating swelling larger and be recorded, and then cooled to let him reduce some objects and records can be larger expansion
gap between the two objects in and out of the objects referred to as shrinkage. Plastic is so objects. According to the water-
absorbent plastics material is divided into two types of processing is divided into two types: the first one is the comparative
water-absorbing plastic, the second is  WSD plastic processing aid non-absorbent plastics. Plastic is easy to absorb water must be pre-processed was dry,
plastic processing aid for wastewater treatment, if the problem does not occur in the processing of the processing, the processing
time since the evaporation of water causes foaming of plastic, the payment of the low viscosity, resulting in forming Poor quality
of plastic products, so that the plastic has a significant influence on the drainage of molded plastic. If done in a plastic air
drying time is too long, it may absorb water again, be the result of water discharge through the plastic work. So those plastic
drainage has been done drying process must protect their drying plastics processing in accordance with WSD Titanium dioxide rutile  the chemical composition of
the material can be divided into: thermoplastics and thermosetting plastics. In order to distinguish the specific purpose, there
are many branches of two plastic names they use are different performance, thermoplastic polyvinyl chloride plastic, polycarbonate
cool, two questions need to plastic molding is not completely the same, in front of a species of mold is to first heat, followed by
cooling the mold you need. So be sure to have on the performance of plastic-depth understanding.
