April 28 world work safety and health day, originated from workers memorial day, was first initiated by workers in the United States and Canada in 1989, aiming to improve the work safety and physical health of front-line production employees.
- high filling polymer processing difficult -
In modern architectural structure, aluminum-plastic plate has become an important component of facade design. In order to ensure that the fire safety performance of aluminum-plastic plate is not affected, flame-retardant fillers such as aluminum hydroxide and magnesium hydroxide are usually added. However, polymer modified materials such as polyethylene and aluminum hydroxide mixture will cause the increase of equipment pressure in the process of polymer mixing.
This will not only lead to the rapid increase of the power consumption of the extruder, the significant increase of the thermal stress of the modified material, but also lead to the mouth die salivation of the extruder - the continuous deposition of the material on the edge of the die, resulting in the process disorder and even product scrap. It not only reduces production efficiency, but also is not conducive to workers' health.
- introduction of new additives
It is a very complex process to develop new special plastics. People are more inclined to improve the existing materials, such as adding fillers and additives to polyethylene and polypropylene to meet the application requirements. As a result, Wacker genioplast? Pellet s organic silicon plastic additive came into being.
It is a kind of granular organosilicon polymer with organosilicon content up to 70%, which can be effectively added to a variety of polymers. The carrier used is fumed silica, which can not only enhance the flame-retardant effect of some flame-retardant fillers in polyolefins, but also effectively improve the extrusion molding effect of products. When the product is used, the additive only needs to be added into the twin-screw extruder or co kneader to mix with the polymer masterbatch. Fumed silica can effectively improve the compatibility of additives with thermoplastic and thermoplastic elastomers.
The product performance can be improved with the improvement of processing technology, so can the production efficiency and production safety.
- efficiency, safety, one stone, two birds -
The addition of genioplast? Pellet s can be described as two birds with one stone in terms of efficiency and safety. It can not only improve the processing performance of polymer, but also improve the production efficiency. It can also effectively solve the problem of die deposition - workers do not need to waste extra time and energy to deal with the deposition of die edge materials, so they can work in a more efficient, friendly and safe environment.
In addition, when genioplast? Pellet s is used in polyolefin compounds with flame retardant fillers, it can ensure that only a small amount of heat will be released in case of fire, and less harmful smoke will be formed, creating an escape opportunity for more people in the fire.
"
The combustion residue (ash) of the modified material containing genioplast? Pellet s will hinder oxygen transport and heat transfer. Both of these effects contribute to the suppression of the rapid spread of the fire.
