the form of additives is the shape of the said additive particles. Additives of different forms, with varying degrees of modification effect. Additive form mainly includes ball, granular, cube, block, and hollow microspheres, and so on. Packing size larger influence on mechanical properties. The general rule is, the smaller the particle size of materials tensile strength, impact strength and elongation at break and hardness has a positive impact. Especially for superfine packing and nanoscale low particle packing such as packing, its positive effect is more obvious. But the positive effect of low particle size fillers on filling systems is not small, namely under the adding amount of low there is a limit. In front of the limit value, the modification with the increase of adding amount performance; And after the limit value, with the increase of adding amount, modified performance declines. Different amount of limit value corresponding to add packing, packing size is smaller, its limit amount is larger.
in the same add system, may at the same time there are several kinds of similar or different additives. The modification effects of the interaction between these additives is different, very different. Synergy refers to two or over two kinds of additives in plastic formula to join together the effect of higher than average for its joining singly. The reasons of the synergy between different additives mainly produced physical or chemical effect between them.
protection against refers to two or more than two kinds of additives in plastic formula to join together as less effective than its individual to join effect of the average. Produce the principle of protection against like synergy, is also the result of physical or chemical effect between different additives. The difference is that the result of the action did not promote their role play, but weakened its due effect.
home and function refers to the plastic formula of two or more than the effect of different additive join equal to its average individual to join effect, this effect is also called the superimposition and match. Home and is the most common action, plasticizer, stabilizer, lubricant, antioxidants, light stabilizer, flame retardant and antistatic agent. Different types and anti aging agent, can provide different types of protection. Lubricants are also used in lubricant and lubricant with outside, so as to play to the internal and surface double lubrication effect. In flame retardant formula, the gas phase type flame retardant and solid type flame retardant with, flame retardants and smoke elimination agent and etc. In addition, different types of plasticizer, antioxidants, light stabilizer, antistatic agent and used are added and role.
the relationship between additives and resin additive in the heat of decomposition. Resin during processing into concrete products, passes through a high temperature melting process, and the general processing temperature as high as 150 - 400° In between. This requires additives in this temperature range doesn't break down and lose its original performance.
the influence of additives on resin processability. Organic additive to add system processing fluidity impact or could improve workability of the resin. And inorganic additives have negative effects on processability of adding system mostly, even if the processing fluidity with varying degrees of decline. Only a handful of several kinds of inorganic additives can improve workability of the add system different level.
