Processing control when ABS contains other materials
ABS contains PC, PBT, PMMA, as, etc., which is relatively easy. It can be used as PC / ABS alloy, ABS modification, etc. it should be noted that PVC / ABS alloy cannot be used;
ABS contains hips, which is also a headache for making secondary materials. The main reason is that the material is relatively brittle, so it can be considered to select a suitable compatibilizer to make PC alloy;
ABS contains pet or PCTA, which is also a headache when making secondary materials. The main reason is that the material is relatively brittle and the effect of adding toughening agent is not obvious; Therefore, it is not recommended to purchase this material for the modification plant.
Selection and control of additives in the modification of regenerated ABS
For the PVC / ABS alloy which is widely used now, it is recommended to use relatively pure ABS, and adjust the corresponding additives according to the toughness and related properties;
For re granulation of fire-resistant ABS recycled material, it is necessary to consider whether to add toughening agent and fire retardant according to the performance and fire resistance requirements of the material. At the same time, the processing temperature is appropriately reduced;
For high gloss ABS, not only PMMA composite, but also PC, as, PBT and other composite can be considered, and relevant additives can be selected to produce materials that meet the requirements;
For the production of ABS fiber added materials, it is better not to simply pass through the machine for some ABS recycled fiber added materials, so that the physical properties will be greatly reduced. It is better to add some materials, glass fibers and related additives.
ABS / PC alloy, for this kind of material, it is mainly to select the appropriate PC viscosity, the appropriate compatibilizer and toughening agent and the reasonable combination.
What is the difference between ABS materials and ASA materials? Can it be mixed?
The full name of ASA material is acrylonitrile styrene acrylate terpolymer, which is different from ABS in that the rubber component is acrylate rubber instead of butadiene rubber. ASA material has better thermal stability and light stability than ABS material, so it replaces ABS in many occasions with high aging requirements. The two materials are compatible to a certain extent and can be directly mixed into particles.
Why is one side yellow and the other side white when ABS material is broken?
This is mainly caused by ABS products being exposed to sunlight for a long time. Because the butadiene rubber (b) in ABS material will be gradually destroyed and discolored under long-term sunlight and thermal oxidation, the color of the material turns yellow and dark on the whole.
How to deal with the problem that the ABS recycled material is always dry and splashed in the injection process?
The main reason for the water spray in ABS injection molding is that the water in ABS material is not fully dried. The exhaust gas in the granulation process is the main reason why the material does not dry. ABS material itself has certain water absorption, but these moisture can be removed by hot air drying. If the regenerated particles are not well vented during granulation, it is likely that the moisture remaining in the particles will remain.
It takes a long time to dry the moisture. If ordinary drying procedures are adopted, the drying materials will not dry naturally. To solve this problem, it is still necessary to start with melt extrusion granulation, improve the exhaust conditions in the process of melt extrusion and avoid residual water in the particles.
Foaming often occurs in light color flame retardant ABS granulation. How to deal with the color gray?
This often occurs when the temperature control of the melt extrusion equipment is poor. Common flame retardant ABS has poor heat resistance of flame retardant components. During the secondary recovery, if the temperature is not properly controlled, it is easy to decompose and cause foaming and discoloration. This situation is generally solved by adding a certain heat stabilizer. Common additives are stearate and hydrotalcite.
Is the alloy you often hear about PC / ABS alloy?
Alloy material refers to a mixture formed by mixing two different polymers. In addition to the unique properties of the two materials, this mixture also has some new characteristics that the two materials do not have.
Because of this advantage, polymer alloys are a large group of materials in the plastic industry. PC / ABS alloy is only a specific material in this group. However, because PC / ABS alloy is widely used in the electrical industry, it is customary to use alloy to refer to PC / ABS alloy. Strictly speaking, PC / ABS alloy is an alloy, but the alloy is not only PC / ABS alloy.
What is high gloss abs? What should be paid attention to when recycling?
The high gloss ABS is essentially a component of MMA (methacrylate) introduced into the ABS resin. Because the gloss of MMA is much better than that of ABS, and its surface hardness is also higher than that of ABS. It is especially suitable for thin-wall large products such as flat panel TV panel, HD TV panel and base. At present, the quality levels of high gloss ABS in China are different. Attention should be paid to the toughness, gloss and surface hardness of the materials when recycling. Generally speaking, materials with high fluidity, good toughness and high surface hardness have higher recovery value.
Some people in the market are selling ABS / PET materials. Can these two materials be mixed with each other? How to sort?
The basic principle of ABS / Pet sold on the market is to add a certain proportion of pet into ABS material and adjust the affinity of both by adding compatibilizer. This is a kind of material that modification enterprises intend to develop in order to obtain materials with new physical and chemical properties.
This kind of work is not suitable for ABS recovery. Moreover, the common equipment in the recovery process is a single screw extruder, and the mixing capacity of the equipment is far lower than that of the twin screw extruder used in the modification industry. In the ABS recycling process, it is better to separate the pet material from the ABS material.
