The activation energy of the vulcanization reaction is gradually reduced to see the particle size of the pigment carbon black.

The activation energy of the vulcanization reaction is gradually reduced to see the particle size of the pigment carbon black.

What are the effects of carbon black on the vulcanization properties of styrene butadiene rubber? Anyang Ruixu Chemical will explain you one by one.

In contrast to styrene-butadiene rubber which is not filled with carbon black, the styrene-butadiene rubber filled with carbon black gradually decreases in scorch time as the carbon black particle size decreases, and the vulcanization time is also gradually shortened.

ML (the degree of interaction between the filler and the filler) decreases with the particle size of the carbon black, and a mutation occurs at 100 nm, indicating that the carbon black has a critical particle diameter at 100 nm; with the decrease of the particle size of the carbon black, physical exchange The density of the joint gradually increases, the density of the chemical crosslink decreases first, then gradually increases, and the total crosslink density decreases first and then increases gradually, which is related to the chemical properties of the surface of the carbon black; The activation energy of the vulcanization reaction is gradually reduced, which corresponds to the tendency that the vulcanization time gradually decreases as the carbon black particle size decreases. As the sulfurization reaction progresses and the conversion rate increases, the activation energy gradually decreases.

China's carbon black export growth rate becomes the second largest carbon black supplier in the US

Notch Consulting Group of the United States recently said that the number of carbon black exported from China to the United States has soared in recent years. In 2010, it has surged from 701 tons in the previous year to 22,300 tons, an increase of more than 30 times. The market research agency said on its website that China is now the second largest supplier of carbon black in the United States, and that Canada is still the largest supplier of carbon black in the United States. The company cited data from the US International Trade Commission (ITC) that in 2011 Canada exported 10.17 million tons of carbon black to the United States, down from 11.91 million tons in 2010, a decline of about 8.9%.

In addition, data released by China Customs recently showed that China's carbon black exports reached a record high in 2011, with exports reaching 487,500 tons, an increase of 116.8% compared with 224,900 tons in 2010. Among them, the amount of carbon black exported to the United States was 26,000 tons, which was about 16.7% higher than that of 2010, and ranked sixth among export destination countries (regions).

General Safety Information:

1. Check if the plug cord was in good condition, and if there is stand before plug into the electrical outlet ; Check if the used glue gun has glue flow through back of the tunnel;

2. wait 5-10 minutes to allow glue to soften, stand up the glue gun on the table when not in use;

3. Touch nozzle to any clean, dry surface you wish to bond, to avoid any impurity stop the nozzle;

4. If the glue could not flow from the nozzle when the glue gun start to work, check if the glue gun are heating;

If glue gun can not be heated, there are following reasons:
1 Plug cord into electrical outlet not properly;
2 Glue gun has been destroyed owing to inner cord short circuit;

If glue gun can be heated, there are following reasons: Nozzle has been stopped by any impurity, ask careerman to manage it.

5. Do not use the glue gun under moist climate, humidity will affect insulation and cause electric shock;

6. Do not touch the nozzle or melted glue;

7. Do not remove out the melted glue stick from the tunnel back side, it will damaged the glue gun as well as scalding person hands.

8. Do not to disassemble or assemble any glue gun accessories freely, it will cause glue gun do not work properly;

9. Keep out of reach of children and stocked it beyond any of Children palpable side;

10. Only used for melting glue stick, no other usage;

11. When in use, there are any glue flow back from tunnel, stop using immediately, wait for careerman clean the glue;

12. Close the power if the glue gun not in use after 15 minutes;

Using methods

1. Glue gun using voltage is 110-220V AC,50/60Hz;

2. Tip gun forward on stand and place a piece of cardboard under the nozzle

3. Use 7-8mm (mini trigger glue gun), 11-12(big trigger glue gun), insert glue sticks through
tunnel at back of gun

4. After power, wait for 5-10 minutes to allow glue to soften

After glue softens, squeeze trigger to feed glue through glue barrel. Excessive force will damage glue gun. Put down nozzle after work, disconnect the power plug
