Comprehensive analysis of calcium carbide industry


Domestic calcium carbide prices fell sharply in October,2013 , average factory price of domestic enterprises in early 2916 Yuan / ton, the average factory price of domestic enterprises at the end of 2753.33 Yuan / ton, down 5.58 percent overall .
Market analysis
Product: an adequate supply of calcium carbide market in October, 2013, the market trading was light, demand is still not good, and the prices fell sharply;
Chain : Upstream Related Products coke , coke market prices relatively stable , Inner Mongolia, Ningxia, Shanxi and other places to make up policy so that the local electric companies operating rate higher calcium carbide ; downstream PVC market fell slightly, enterprises underemployment , downstream trichlorethylene prices fell slightly , the overall market demand is poor.
Market outlook forecast :BouLing Chemical Co., Limited   experts predict due to domestic calcium carbide excess capacity, and downstream PVC, trichloroethylene market downturn, calcium carbide market next week will be weaken. Experts predict
Industry Status
China calcium carbide industry as a basic industry has a long history, according to the National Bureau of Statistics data show that in 1990 Chinese production was 2.28 million tons of calcium carbide, calcium carbide production in China in 2002 reached 4.25 million tons, in 2003 jumped to 5.38 million tons. From 1990 to 2005 these 15 years, calcium carbide production in 2005 was about four times in 1990, production reached 8.95 million tons, up 34% over 2004.
2004 calcium carbide industry, huge profits, induced expansion growth industry. Then calcium carbide industry began a grim situation, caught between the survivals of hard journey. While overall investment in China's chemical industry continue to maintain high growth momentum, but the calcium carbide industry's overall competitiveness and ability to fight against risk is still low, excess capacity, low level of technology , environmental pollution , high energy consumption , and even transportation risks and so become a constraint industry development bottleneck.
From 2005 Annual calcium carbide industry statistics, domestic production was 8.95 million tons of calcium carbide totals, compared to 2004 increased by up to 34 %, while the downstream industry PVC production growth rate was 32.29%, overcapacity contradictions further exacerbated the trend. Calcium carbide industry to become a production capacity, production continued to grow, rising costs, sales and marketing industry has been repeatedly suppressed.
The market price
2004 was the heyday of China calcium carbide  industry development; the market price once reached 3400 Yuan/ton. From 2000 to 2004, China's calcium carbide industry along with the great development of domestic PVC industry appeared a golden growth stage of the calcium carbide production scale larger manufacturers jumped to more than four hundred, including production capacity in more than 50000 tons/year 40-50 or so, as for the scattered all over the country backward technology, small capacity of non-standard carbide production enterprises are difficult to count, one of the largest manufacturers, production capacity has reached 300000 tons/year, the smallest is less than 10000 tons/year. Manufacturers are mainly distributed in the power generation capacity is concentrated, lime and calcium carbide production raw material blue carbon resources is rich in the northwest, north China and other regions. Also it is because the calcium carbide prices in 2004, as a direct result of 05 production soared, expansion speed, the consequence is that the price will fall. <!--[if gte mso 9]><xml><w:worddocument><w:browserlevel>MicrosoftInternetExplorer4</w:browserlevel><w:displayhorizontaldrawinggridevery>0</w:displayhorizontaldrawinggridevery><w:displayverticaldrawinggridevery>2</w:displayverticaldrawinggridevery><w:documentkind>DocumentNotSpecified</w:documentkind><w:drawinggridverticalspacing>7.8</w:drawinggridverticalspacing><w:view>Normal</w:view><w:compatibility><w:dontgrowautofit/><w:balancesinglebytedoublebytewidth/><w:donotexpandshiftreturn/><w:usefelayout/></w:compatibility><w:zoom>0</w:zoom></w:worddocument></xml><![endif]--><!--[if gte mso 9]><xml><w:latentstyles deflockedstate="false" defunhidewhenused="true" defsemihidden="true" defqformat="false" defpriority="99" latentstylecount="260" > </w:latentstyles></xml><![endif]-->

the problem of Surfactant should be noted

Surfactant should be noted that the problem
( 1 ) surfactants are usually different chain length homologues mixture of surfactants with various other chemical products is that there is little surfactant products pure single molecular structure , mostly prepared by a mixture of different chain lengths homologues , the main raw materials derived from petroleum surfactants or oil , the oil is a mixture of various hydrocarbons , esters of fatty acids with glycerol various oils are also formed , the surface active agent is also made ​​of a mixture of products .Such as soap is actually sodium stearate, sodium palmitate , sodium laurate , oleate mixture of various salts of fatty acids , and fatty alcohol ethoxylates not only raw material is a mixture of fatty alcohols with different carbon chain lengths , and add ethylene vinyl rot number is different , so the product is not a variety of alcohols , mixtures of different ethylene oxide adduct i representing the proportion of the various components of the mixture has a great influence on the nature of the surfactant .
( 2 ) Effect on other components in the detergent surfactant
The presence of detergent formulations of organic and inorganic salts of fatty alcohols and other polar water-soluble polymer has the nature of the surfactant will greatly influence the performance of their specific surface tension of surfactant solution , the critical micelle concentration and emulsification, solubilization, foaming foam stabilizing properties change as a result of the composition and interaction between the surfactant molecules .
General surfactant industry products almost inevitably contains a small amount is not separated by product and raw materials, but these organic impurities often greatly influence on the nature of the surfactant solution, such as anionic surfactant fatty alcohol sulfate sodium fatty alcohol reaction often contain not fully in the raw material, it has a great influence on the surface active agent of the above performance and show the longer the hydrocarbon chain the greater the influence law of fatty alcohols. And some of the material as additive added to the factory in detergent formulation such as anionic surfactant C16H330SO3Na almost insoluble in water at room temperature, but if add urea in formula and N - methyl ethyl amide (CH3CONHCH3) or dimethyl benzene sulfonic acid sodium, its solubility in water increased significantly. So in detergent to join all kinds of washing auxiliaries and additives to improve the performance of the surfactant.

The fourth generation of organic silicon products


The fourth generation of organic ](amino modified silicone oil) has become the mainstream of containing silicon softener; amino silicone oil has four important parameters: ammonia value, viscosity, reactivity and granularity. The four basic parameters reflect the quality of amino silicone oil, and will greatly affect the style of the treated fabric. Such as handle, whiteness, light, and to the difficulty of the silicone oil emulsion.
Ammonia value
Properties of the amino silicone oil to give the fabric such as softness, smooth, plump degrees are mostly from amino polymers. Amino content can be represented by ammonia value, it refers to the amino silicone oil and 1 g the number of 1 ml equivalent concentration of hydrochloric acid. Therefore, ammonia value directly and is directly proportional to the mole percentage of the content of amino silicone oil. Amino content is higher, the higher the ammonia value, finish fabric feel more soft, smooth, this is because the amino functional groups increases, the affinity of fabric has greatly increased, a more neat arrangement of molecules, so as to give the fabric feel soft and smooth.
viscosity
Viscosity is related to the polymer molecular weight and molecular weight distribution. Generally speaking, the greater the viscosity, the higher the molecular weight of the amino silicone oil, in the film on the surface of the fabric, the better, feel more soft, smooth, the better, but its permeability is poor, especially for overtwisted fabrics and fine denier fabric closely, amino silicone oil is difficult to penetrate the fibers, the influence of fabric properties, viscosity is too large will worsen or difficult to make the emulsion stability of microemulsion. Generally not only through to adjust the product viscosity, often by ammonia value and viscosity to balance the performance of the product. Ammonia value usually low, high viscosity is needed, so as to balance the fabric soft performance.
reactive
With reactive amino silicone oil, can produce when finishing the crosslinking, and the crosslinking degree rise, will increase the fabric smooth feeling, softness and fullness, especially for more flexibility. General amino silicone oil, of course, when the crosslinking agent or increase the baking conditions, can also increase the crosslinking degree, and thus can improve the springback. Hydroxyl or amino end amino silicone oil, the higher the value of ammonia, the crosslinking degree good, is also the better elasticity.

More Use about Hydrazine Hydrate

Hydrazine Hydrate as Fuel cells
Hydrazine hydrate can be used as an alternative to hydrogen in fuel cells. The chief benefit of using hydrazine hydrate is that it can produce over 200 mW/cm2 more than a similar hydrogen cell without the need to use expensive platinum catalysts. As the fuel, it is liquid at room temperature, it can be handled and stored more easily than hydrogen. By storing the hydrazine hydrate in a tank full of a double-bonded carbon-oxygen carbonyl, the fuel reacts and forms a safe solid called hydrazone. By then flushing the tank with warm water, the liquid hydrazine hydrate is released. Hydrazine hydrate has a higher electromotive force of 1.56 V compared to 1.23 V for hydrogen. Hydrazine hydrate breaks down in the cell to form nitrogen and hydrogen which bonds with oxygen, releasing water.

Hydrazine Hydrate as Gun Propellant
A mixture of 63% Hydrazine Hydrate, 32% Hydrazine Nitrate and 5% water can be used as a standard propellant for experimental bulk-loaded liquid propellant artillery. It is notable that the propellant mixture above should for being one of the most predictable and stable, with a remarkably flat pressure profile during firing. inadequate ignition usually cause misfires. The movement of the shell after a misignition causes a large bubble with a larger ignition surface area, and the greater rate of gas production causes very high pressures, sometimes including catastrophic tube failures, that's always explosions.

what is Hydrazine Hydrate?


Hydrazine Hydrate  law has clean, atmospheric pressure, the treatment is simple , conversion rate and other characteristics, its yield and catalytic hydrogenation quite , but does not restore the cyano nitro molecules , but the amount of hydrazine hydrate is not the case reduction of azo group ; especially suitable for the multi-purpose batch reactor pressure low-volume production of fine chemical products . In recent years, as people's awareness of ecological and economic growing, hydrazine hydrate catalytic reduction of nitro compounds become a research focus, focus of the study focused on inexpensive, reusable catalyst development, the impact on the molecular structure of nitro reduction reaction and so on.
The influence of the catalyst
Hydrazine hydrate 55% reduction using the catalyst at the beginning of the study mainly for precious metals (Pt, Pd, Ru, Ni, etc.). The study found that the Raney Ni is better than Pd/C catalyst effect; And adding trace Raney Ni Pt dramatically improve catalytic effect, shorten the reduction reaction time.
Because precious metals prices high, people turned to cheap as hydrazine hydrate reduction catalyst such as iron compounds. Line at Westminster, etc to nitrotolueneas reactants, system to study the different forms of iron oxide influencing on the yield of reduction reaction, the result shows that in six kinds of iron oxides, beta iron hydroxide oxygen catalytic effect is best, in the catalyst dosage of 10 g/mol, nitro conditions, also from a rate of 93.2%; Followed by goethite, the yield of 55.2%.
The influence of the reaction system
Can be used when hydrazine hydrate reduction water medium, and organic solvent medium can be applied. But not in chloroform, acetone, ethyl acetate and other organic solvents.
Due to solvent to influence the surface state of the catalyst, which affect the activity of the catalyst, therefore solvent in hydrazine hydrate catalytic reduction reaction has a certain degree of influence.
According to market analysts hydrazine hydrate statistics, in 2013 the domestic market of hydrazine hydrate still mixed, although in the short term prices strong, but with the release of new capacity or promotion enterprise's work load, the market supply once recovery, hydrazine hydrate prices will inevitably fall into channel. So companies in price increases at the same time, should also be rational analysis of the supply and demand of the market supply of goods.

The impact of vinyl resin market
A country FPR industrial level of quality and performance, in a sense, the use of vinyl resin can be used to express the amount. In developed countries, vinyl resin wide range of applications , in addition to our domestic common outside corrosion engineering , and even onyx bathtub vinyl resins are produced , and of course travel so the field. Although in recent years the market of vinyl with extraordinary speed rapid development , however, from more than one million tons of unsaturated resin in terms of the total market volume , the total amount of vinyl resins and applications is still very, very limited, which largely restricted FPR improvement of product performance .
In China, Vinyl resin application is greatly limited, mainly in terms of the relative unsaturated polyester resin; vinyl resin’s price is too high. Due to the current large scale production on several vinyl resins, unsaturated resin ordinary gross margin is generally 300-800 Yuan, while the majority of Maori vinyl resin is basically the number of times or even more. This creates a monopoly of the market has been invisible , making the downstream market only in the non -use is not a situation of helplessness was compelled to choose vinyl resins, vinyl resins thus greatly limiting the expansion of the market .
