The difference between genuine and imitation BBS blocking compound of "Three-proof" BBS
Imitations and "three-proof" BBS blocking group material authentic comparison, the appearance of the gap is huge, the internal performance is a world of difference, after experimental analysis of technical personnel, imitations in the density, bubble holes, substrates, etc. can not reach the standard of anti-condensation governance, and one of the most fatal hazards is the production of coking layer.
Imitations and "three defences"BBS blockingComparison of the group material genuine, the appearance of the gap is huge, the internal performance is a world of difference, after the technicians experimental analysis, imitations in the density, bubble holes, substrates, etc. can not reach the standard of anti-condensation governance, and one of the most fatal hazards is the production of coking layer.
"Three defences"BBS blockingThe self-levelling expansion blocking technology used in the group material has very high requirements for research and development, production and other aspects. The core technology of some imitations and cottage products on the market is not up to standard, and they are unable to control the speed of temperature climb during chemical reaction, and the reaction is incomplete to produce a coking layer.
Coking layer formation process generates a temperature of 150 ℃ ~ 200 ℃, far more than the bottom line of the safe operation of the cable, resulting in high-temperature erosion of the cable, cable sheath aging cracking, loss of the design of the insulating properties of the cable, easy to cause the cable ground breakdown, at the same time, coking layer of material is hard and brittle, very difficult to remove the integrity of the need to use a violent tool such as an electric hammer, often accompanied by the removal of the coking layer, the outer wall of the electrical box, cable often accompanied by the removal of the coking layer, the outer wall of the electrical box, the cable jacket, the outer skin of the cable will also be completely destroyed, resulting in irreparable damage.
The use of imitation base plate blocking lost effective airtight, so that condensation can take advantage of, and the cable is damaged by high temperature. These are like time bombs, always threatening the smooth use of electricity in the region, safe use of electricity.
The country is increasingly strengthened in the fight against counterfeiting efforts to prevent counterfeiting and counterfeiting is equally important, the user needs to protect their rights and interests, strengthen the investigation. Imitations of the airtight sealing performance and the "three defence" blocking group material compared to the huge difference between the procurement and the use of special attention, so as to avoid unnecessary trouble caused by the later re-blocking.
