Specifications

White carbon black
1.improve the tensile strength of rubber
2.good reinforcing performance
3.high wear resistance

1.Introduction:

White Carbon Black(Precipitated silica) with special physic-chemical properties, work as reinforcing transparent fillers highly valued in formulation of rubber-based blends. They lead to enhanced tensile strength, tear strength and abrasion resistance and increase hardness of vulcanized rubbers. On the other hand, They reduce consumption of rubbers and therefore reduce the cost.

2.Application:

It is widely used in silicon rubber, constrction sealant, coating, rubber, shoes, medicine, resin processing, printing ink and other industries.
1) Silicon Rubber: Improves silicon rubbers durability, rebound rate, and anti-distortion performance.
2) Plastics Industry: Improves plastic s tenacity, strength and prevents water absorption.
3) Coating Industry: Prevents agglomeration and drip. Thixotropic  additives. Increase denseness and smoothness of paint.
4) Medicine Industry: Increase denseness ,floating , carrying function in medicine. It also can be used as the pesticide powder and anti-agglomeration.

3.Features:

1) Good activity and the absorption rate.
2) High reinforcing effect and chemical stability.
3) Porous surface area.
4) Good dispersibility.

Q:How does active charcoal catalyze in some chemical reactions?
Activated carbon is generally in the catalytic reaction to do more carriers, has not yet seen its catalyst to report.
Q:What is a catalyst and what is it do?
A catalyst is a substance that increases the rate of a chemical reaction.
Q:what is a catalyst ?
substance accelerate a chemical reaction
Q:Will the chemical catalyst not reduce that?
Why is it done? Although the catalyst does not react chemically, the catalyst itself is deteriorated and is not always used
Q:Will the catalyst change the reaction rate in the chemical reaction?
Many of the catalysts are specific in varying degrees, and when added to the chemical reaction system that it can catalyze, it must change the rate of chemical reaction, and of course both positively and negatively catalyzed. Chemical reaction rate, it can not be called a catalyst.
Q:In the chemical calculation, the quality of the catalyst should not be counted before and after the reaction
It is not the same .. because the quality of the catalyst will not change .
Q:Write a chemical formula in a chemical laboratory without the use of a catalyst for oxygen
2Na2O2 + 2H2O = 4NaOH + O2 ↑
Q:What is the difference between a catalyst and an inducer in a chemical reaction?
The catalyst does not participate in the reaction, but only the carrier of the reaction; the inducer will participate in the reaction
Q:PT / AL_203 catalyst and the main chemical use
Yueyang Eagle Hill Petrochemical Plant
Q:What are the examples of chemical catalysts used in life?
The use of new synthetic materials makes life more comfortable. Only wood, sand and grapes are natural building materials, but they need to be combined and protected with synthetic chemicals. Cement is a chemical product, As the adhesive used in the laminate and the metal used in the nail are chemical products, the glass is made by the chemist, and the improved product, such as heat-resistant glass (trade name Pyrex glass), becomes more tough. Paint is chemist design and creation, and many modern solid materials are also the same. Plastic is synthetic, they are used in kitchen and bathroom utensils, also used in the name of the product called Formica bakelite and its related materials, beverage bottles, Cutlery and utensils. Porcelain is made by chemists and used in kitchen and bathroom sinks and other fixtures. Metal is made of chemical changes made from ores. Aluminum was once a laboratory treasure, but used An electrochemical method, which now can be easily made from alumina, at least a portion of the carpet and decorative fabric used for the use of synthetic fibers and synthetic dyes to color. Freezer and air conditioner with special chemicals as coolant ; Gas and gas stoves can be used syngas or natural gas, the combustion process is still the chemical change.Our room with gas or oil industry to produce fuel to heat, this fuel is from the natural crude oil refining and chemical We have made use of synthetic chemical products and materials made in the chemical processing industry, such as plaster or wall panels, outer panels and roof panels, as well as tiles and carpets, to heat our buildings. The stove itself and the distribution of heat The pipes are made of chemical products - metal, insulating materials and ceramics. The current enters the home through the copper wire of the outsourced insulator, both of which are products of the chemical processing industry
