High quality Butyl road tyre inner tubes available in a choice of valve lengths for use with different rim depths without resorting to leaky extensions. The most important constituent of the inner tubes is butyl, a synthetic rubber with a very low gas permeability. This means that the inner tube retains its required pressure longer. Vredestein inner tubes are autoclave. Butyl rubber gloves Butyl rubber has excellent impermeability, and the long polyisobutylene segments of its polymer chains give it good flex properties.

Two imported crystal lamps are light and heavy, and workmanship is uneven. In June this year, Ms. Wang purchased two crystal chandeliers at the Avon Kaidi Lighting Fair in Gudun Road. The same model and different colors, each unit price is more than two thousand yuan. According to the business introduction, the two lamps are all imported from Egypt.
After the lamps were delivered to the home in August, Ms. Wang found that the external texture of the two crystal lamps was somewhat different. The light weight of the two lamps is different. On the workmanship, one lamp is rougher than the other. She suspected that the crystal of one of the lamps was not imported from Egypt, but when negotiating with the merchants, the other party insisted that the two lamps were imported from Egypt.
The explanation of the merchant does not convince Ms. Wang that she hopes to find an authority to identify the crystal and determine whether it is domestic or imported. I have learned that the crystal lamps sold on the market are basically not natural crystals, but crystals, but even if they are the same, the quality is very different. High-quality Egyptian imported crystals and ordinary domestic crystals, the content of lead in the inside are different, it will affect the quality.
Ms. Wang said that if it was identified that the crystal on the luminaire was not imported from Egypt, she asked the merchant to give a reasonable refund.
Appraisal agency: Crystal can not check whether the weight of the two crystal lamps proposed by Ms. Wang and the difference in workmanship are made. The explanation of the Aiwenkaidi lighting decoration of Gudun Road is that the lamps have electroplating links during the manufacturing process, and the lamps have Different degrees of wear and tear, the weight of the two crystal lamps are not completely consistent; and the difference in work color is due to the difference in the color of the two lamps themselves, the white ones are naturally brighter, and the colored ones are naturally dull.
Subsequently, the reporter asked the Zhejiang Fangyuan Testing Group's Gold Jewelry Inspection Department and Zhejiang Jewelry Jade Jewelry Appraisal Center, all of which were told that they could only identify whether the crystal was natural crystal or synthetic crystal. It was impossible to check whether the crystal was made in China or imported. As for the detection of the internal composition of crystal (or crystal), or the comparison of the quality of two crystals (or crystal), it is not within the scope of business of these two institutions.
Can the merchant prove that the two crystal lamps sold by him are imported from Egypt? The staff of Ai Wenkaidi Lighting Fair said that they can produce inspection sheets of Egyptian imported crystals from the manufacturer (the inspection list is located at the headquarters of Hangzhou Avon Kaidi in Shennan Road, not in Gudun Road). The inspection form is provided by the manufacturer and is not from a third party inspection agency.
If Ms. Wang is dissatisfied with the colored crystal lamp, we can change her to white, or she can look at other styles, we can also change her. The staff said. In this regard, Ms. Wang said that after seeing the business checklist, they will negotiate again. The newspaper will continue to pay attention to this matter.
