[Product space] strong anti-static masterbatches Which?
What is static
I.e. stationary relative to the charge, usually negative charge due to friction between different objects generated in the surface brought.
Electrostatic discharge
Refers to objects with different electrostatic potentials between the object due to direct contact or electrostatic induction caused by the transfer of electrostatic charge usually refers to the electrostatic field after energy reaches a certain level, the breakdown during medium discharge phenomenon.
Reason static electricity
1 reason microscopic theory based on atomic physics, when the material is electrically neutral equilibrium. Since the contact of different substances to produce atomic electrons gains and losses, so that the material loses power balance, static phenomenon.
2 macro reasons: the friction between the object and heat, to stimulate electron transfer; electromagnetic induction caused by uneven distribution of surface charge; the combined effect of friction and electromagnetic induction;
Plastics Attractions
Plastics are all polymer materials, surface resistivity and the volume resistivity greater than 12 10 or more of th. Therefore, given the good insulating properties of plastic materials. And precisely because of this reason he can easily generate static electricity, because the plastic and its products in the production, handling, contacts, separation, friction, collisions, are involved in the case of electromagnetic induction and may never even be possible to avoid these situations. That brought the factors of static electricity. How effective prevention and control, which is of concern for many years and look forward to the topic.
The concept of plastic antistatic
When plastics and products surface resistance: greater than 10 th time easy to produce static electricity; between 8-10 th with certain anti-static properties; between 6-8 th have good anti-static properties; 4 having between -6 th best anti-static properties; When you reach the fourth power of the following have considerable conductivity, belonging to the conductor of the semiconductor material.
Placke Plum antistatic masterbatch
I. Features: Easy to use, excellent performance, can be widely used polyolefin antistatic plastic products, such as PP, blow molding, extrusion, injection molding and casting processing.
Second, the major technical indicators:
Appearance: particle size, color uniformity
Heat resistance: ≥200 ℃
Surface resistance: 108-1012Ω
Third, the use ratio and methods:
Can be used after the proportion of 20-30 (depending on the requirements of the product may be), this product will be mixed with the raw resin: Press 1
IV Notices
After the masterbatch use, the remaining masterbatch should be promptly sealed packaging, to prevent moisture absorption.
Changzhou Hongmei Placke Masterbatch Limited (formerly Changzhou Hongmei Plastic Masterbatch Co., Ltd.) was established in 1990, is located in Changzhou High-tech Development Zone, China's earlier in the development and manufacturing of plastic masterbatch specialized enterprises, is currently the largest in east China's polyolefin plastic masterbatch and functional master batch manufacturers.
