Plastic brightener is a new functional additives often appear in the plastic market in recent years; now on the market called plastic brightener products can be divided into four categories.
The following are the characteristics of these four categories and play 1, polyethylene wax Characteristics: low molecular wax and ethylene polymer, melting point 101 degrees. Play: used as a lubricant, can enhance the fluidity of the melt, but too much will be chromatized, so that the product is not qualified, especially the wire.
2, high melting point wax Characteristics: low molecular preparation of wax, melting point of about 110 degrees; Play: used as an external lubricant. 3, polymer substances and wax grafting **** polymer Characteristics: relatively high molecular weight, melting point can be more than 210 degrees.
To: is a film on the surface of plastic products to enhance the brightness and smoothness of the surface of plastic products. 4, imported plastic brightener (currently the real imported, only granular) Characteristics: high molecular weight (about 17,000 or so), melting point of an average of 160 degrees.
Play: in the plastic products surface film, to enhance the plastic products surface brightness and smoothness.
2. What are the characteristics of plastic spraying
Advantages of plastic spraying: 1. Annealed plastic molding is easy to form internal stress, easy to crack after painting stress concentration. 2.
Annealing treatment or surface treatment can be used to eliminate stress. Annealing treatment is the ABS plastic molding parts heated to below the heat distortion temperature, that is, 60 ℃, insulation 2h.
As a result of the use of such a process requires a large investment in equipment, therefore, can be used for the whole surface treatment technology, that is, configure to eliminate the internal stresses of the plastic parts of the solution at room temperature on the surface of the plastic parts can be 15 ~ 20min of treatment. 2. Degreasing the surface of the plastic parts are often stained with grease, Hand sweat and mold agent, it will make the coating adhesion deterioration, coating cracking, blistering and peeling.
Degreasing should be done before coating. Plastic parts are usually cleaned with gasoline or alcohol, and then chemical degreasing should be thoroughly cleaned after the residual lye on the surface of the workpiece, and finally cleaned with pure water, air dry or drying.
3. Plastic spraying some of the advantages
Here is a brief introduction to the advantages of my company in the plastic shell spraying embodiment: 1, plastic parts silkscreen (curved or flat), laser engraving, hot stamping business has been the company's important business, to meet the needs of special customers.
2, plastic parts spraying test, our company has a variety of coating testing equipment more than one, can be detected at the same time adhesion, impact resistance, corrosion resistance, weather resistance, abrasion resistance, to protect the product for a long time to store the use. 3, plastic parts spray processing can be used in oil spraying, PU spraying, environmentally friendly UV paint, water-based paint, but also the use of varnish spraying, can provide customers with a variety of colors of single-color or color spraying business, and is not subject to the limitations of the size of the object, there is a great deal of flexibility.
Plastic plastic parts spraying process: on the piece → dust → spray primer → drying → medium coating → drying → top coat → drying → UV paint → leveling → UV light curing → cooling → the next piece. Spraying process is customized according to the product coating requirements, different factories process is different.
4. What are the advantages of plastic spraying
What are the advantages of plastic spraying?1. Diversity of methods: up to 10 kinds of methods, thus providing a variety of means for the preparation of coatings.
2. Wide range of coating materials: a wide range of spray materials. A wide range of types. Thus, various types of coatings can be produced, in addition to metal. Alloys, and most of the compounds and their mixtures, at the same time, if covered with a coating of dissimilar materials, but also to obtain a protective layer with special properties.3. The structure and performance of the spray layer can be designed according to the requirements of a variety of specific conditions, as a way to repair the excessive cutting part and the wear and tear part of the need to increase the size of the part more, can form a few millimeters of the surface layer, wear-resistant life is longer.
4. Process simplicity: with the general spraying method of preparing coatings, less process procedures. Easy to operate, and plastic spraying equipment structure is simple. Easy to move, in favor of field operations. The above is the introduction of several advantages of plastic spraying, we now have a deeper understanding of the material spraying which.
