Charge treasure, had been everybody gives an one of indispensable articles for use.
A lot of person selected charge treasure, the standard is very simple: Good-looking, cheap, allow generous!
Very few however somebody notices, oneself buy charge is treasure eligible product after all?
A few days ago, guangdong province pledges inspect bureau selectived examination of on market 80 batch charge treasure product, have 29 batch product unqualified, fraction defective is approached 4 into.
This second detect, basically center in nine respect.
The discovery in detecting, charge unqualified project basically is in treasure centrally clog concussion, flame retardant requirement two respects.
Clog concussion detects: Rejected product explodes directly
The engineer of academy of Guangdong product quality supervision and inspection expresses: According to national level GB31241-2014 portable electron product uses lithium ion batteries and demand of batteries group security, charge after the in-house batteries of treasure product is sufferring 9.1 kilograms clog to fall to bump batteries surface from 610 millimeter place, in-house batteries not on fire, do not explode, just be the product of qualification of a quality.
Below such requirement, these are unqualified charge the batteries of treasure was not passed detect.
△ is waited for detect charge treasure batteries
Sufferring a clog to pound left and right sides of the 30 seconds after detecting
Batteries produces severe reaction, then explodes.
The engineer expresses: Clog concussion detects is to charge in recent years in treasure sampling observation often unqualified project. And in this second sampling observation, the following company produces charge treasure product all did not pass clog concussion to detect.
Charge treasure clog concussion detects concern charge the use of treasure is safe, important rate is self-evident. In last few years, it is to charge all the time the key that treasure product quality selectives examination selectives examination project.
Crust is not flame retardant, support combustion instead
Charge another of treasure safety main index, it is to charge the crust anti-flammability of treasure.
Charge treasure crust besides metallic crust, what more products use is plastic outer covering.
According to national level: Charge treasure gives out heat in electric core or other part below the circumstance of out of control, crust should be prevented effectively or alleviate igneous situation spreads, avoid to cause more serious harm.
Detect in the engineer in the process, some charging treasure crust encounters fire not to burn or go out after brief combustion, but after some sample receive bright ammunition burn quickly however, last very long.
This kind of use blame is flame retardant of material charge treasure crust, charging after treasure happening on fire explodes, cannot rise effectively flame retardant the effect, can support combustion even, cause more serious combustion explosion.
And some product crust, use lighter even can light, and be lighted quickly use up.
The engineer expresses, consumer is being used charge in the process of treasure, often put in the phenomenon that charges all the time. Inferior product is in overcharge process, incidental short circuit, on fire. If do not have seasonable discovery, flame retardant unqualified product will bring the loss that estimates hard.
And in rejected product, flame retardant the product big batch with unqualified project exists.
The following company produces charge treasure product is flame retardant project all unqualified.
Two rounds in detecting, concussion of gravity of the following product detects and crust is flame retardant detect all unqualified:
Guangdong pledges Tang Sui of check courtyard assistant dean makes the same score speak bluntly: (charge treasure) state of integral product quality or question are more, still should increase the quality to this kinds of product superintend continuously.
Phenomenon of capacity theory mark is serious
Detect besides afore-mentioned safe project besides, this second selectived examination to still increase capacity of similar and effective output to wait for product function index to detect.
The engineer expresses: Charge treasure product mark has nominal capacity numerical value, convenient consumer understanding outputs power. But detect through large quantities of quantities discovery, charge rated output capacity puts treasure generally in be unworthy of the name or the title, the phenomenon of empty tender random bid.
This nominal when 30 thousand milliampere charge treasure, actual measurement has 10 thousand only when 8 1000 milliampere. Achieve only nominal 60% the left and right sides.
This product is nominal 10 when installing, but when install actual measurement has 6 only, also achieved only nominal 60% the left and right sides.
And the product with the oldest discrepancy that discovers in the product, real test value is achieved only 40% nominal.
Such product, consumer of influence of apparent meeting huge is used charge the effect of treasure. This second in detecting, there is appearance of mark of theory of capacity of presence of 49 batches product in 80 batch product!
Partial businessman is produced for drive up taste price, capacity of intended empty mark.
And another part businessman wraps what mount marks in the product is to charge the electric core capacity of treasure, and be not actual output capacity. When electric core capacity is being changed into actual output capacity, meeting somewhat loss. Because a lot of manufacturer make a standard inferior, loss of actual output capacity is very big, because this is not willing,line out outputs a capacity actually.
The position in the life is produced to accentuate gradually in ours as electronic product, charge treasure had become our indispensable thing.
So giant demand nature caused the plan of a lot of businessmen.
According to engineer introduction, charge the treasure doorsill that make is very low, all raw material can be bought easily from electronic market. This also attracted the small business of capability of technology of a lot of lack. And leaving the case that accuse without product quality, these enterprises produce charge nature of treasure product quality assures hard.
The hope can be increased about the branch to charging the quality of treasure product is superintended. Invite customer buy, use more be at ease, such charging treasure talent is real is our hand a medium " treasure " .
