Classification of foshan jigsaw puzzle of raw material is how

Foshan jigsaw raw material classification: polymer is made up of many small and simple structure small molecules ( 单体) By covalent bonds to combine. There are many types of polymers, generally if the change of heat to classification, it can be divided into two major categories of jigsaw puzzle raw materials: a, thermosetting plastic ( 热固性塑料) : refers to the heated, can make the molecular structure combined with reticulate type, but a combination of reticulate polymer, even heating won't soften again, show the so-called [ The reversible change] Change, is the molecular structure ( A chemical change) Caused by. Second, the thermoplastic ( 热塑料) After: refers to the heat can melt, can flow to the mould cooling after forming, again after heating and melting plastic, can use of heating and cooling, make its produce [ The reversible change] ( Please liquid - solid) , is the so-called physical change. Jigsaw puzzle according to the main application range points are general plastics such as PE/PP/PVC/PS, engineering plastics such as ABS/POM/PC/PA several. There are some special plastic, such as resistance to high temperature and high humidity and corrosion resistance and other modification of plastics for special use. Material used and color processing 1 puzzle toys. Foshan puzzle toys most of the raw materials can be recycled, but due to the double plastic ( Material floolwing) More brittle than general materials, so can only be mixed new material ( The raw material) Used together, the largest percentage is over 25% is more appropriate, at the request of customer standards for the principle. Various types of plastic material for the melting point is different, injection pressure of different, must not be confused in production. 2. Because jigsaw puzzle to cooperate with color, plastic raw materials can be divided into: pumping aggregates, pigments, color material, and recently appeared to add liquid coloring in the plastic raw materials. Take grain of raw material is mixed pigment into the raw material, every grain of the plastic material have been shaded, so to form stable product color evenly. Color toner and kind of material is mix color or toner raw material use, low cost, and don't need to store large amounts of non-ferrous materials. But color is not stable, more difficult to control in the production of unity.
